How to Get Your Eclipse-Integrated NDK On Here are the few steps

Sooner or future in your Android game development attempt you may find the need to have some code that runs faster. It turns out that Android code written in C runs 10-100 times as fast as its Java counterpart. I can verify this, as I've already moved a few major components in my newest 3D game engine into native land. That's quite a boost but let's face it - C is a pain in the ass and while Eclipse is great for Java, it's not for C, right? Wrong. 

Here's how to set up a super speedy NDK development environment.

First of all, Eclipse can do way more than just Java. Java is what it's great at and what it was designed for but the architecture makes it so that it can handle any language effectively, including C. There is a component called CDT that allows for C/C++ Development in Eclipse. I'm getting ahead of myself, though. Here's what you need:

Android NDK (Native Development Kit)

Eclipse CDT (C Development Tooling)

If you're in Windows, you'll need Cygwin with the develop packages installed (Especially GCC and Make)

Here's what you need to do:

Install all 3 of those things. I like to install my NDK to c:\Android_NDK. I'll refer to that dir for the rest of this article.

Get acquainted with the NDK. You need to configure each project as an "app" in the c:\Android_NDK\apps dir. Just take a look at the examples. They work and are thorough.

How to test your NDK:
Run cygwin
cd /cygdrive/c/Android_NDK
make APP=hello-jni

It should roll up without errors. If you are lacking GCC or Make or any other develop packages, you will want to run your Cygwin setup again and check to make sure that all of the development packages are installed. If you have strange errors, I suggest reporting them in the NDK user's group.

Once your NDK is running, you can add an app for your project and set up the basic native framework for your project. Please refer to the examples for this part. You will need a specific build file that tells the compiler what sources to compile. JNI code is usually located in your Android project's jni folder. A file called Android.mk will need to be in there which instructs the compiler on what to compile.

After you get the basic configuration done, you will want to start writing some C. NDK uses Java's standard JNI bindings to work. All of the existing documentation on JNI should apply from this point forward. What to code is beyond the scope of this article.

Now for the good part :

If you've done any NDK work, you're probably used to using a text editor or vim or some other editor to edit your C/CPP then running make APP=myapp every time to build, then clicking refresh on your project in Eclipse and then hoping that the shared object library file that gets deployed is current. What a pain in the ass! There's a much, much better way.

Now that you have CDT installed, you can edit all of your C/C++ right from Eclipse. If you right click on a C/CPP source file, just pick Open With--C/C++ Editor and it will use the CDT editor. Much nicer! It won't be able to figure out what the code is doing because it's not compiling it, but it will make editing nice and all in one spot.

Building is a snap as well. Ever used builders in Eclipse? They are configurable triggers that will execute what you configure and refresh resources for you. Make sure you know if you're on the old r3 NDK (upgrade if you are - you should be on r4) and if so, I put different instructions in this list for the different versions. Here's how I set mine up:

Right click on your project, pick properties.
Select "builders" from the left-hand list.
Click "New..." on the right side.
Select "Program" as the configuration type.
I name mine "Native Builder"
Location - c:\cygwin\bin\bash.exe
Working Directory - c:\cygwin\bin
Arguments -
(for NDK r3):
--login -c "cd /cygdrive/c/Android_NDK && make APP=myapp"
(for NDK r4):
--login -c "cd /cygdrive/c/<myapp_project_dir> && /cygdrive/c/Android_NDK/ndk-build"
Make sure you have the two hyphens before login and the quotes after the hyphen-c
Now go to the refresh tab
Check "Refresh resources upon completion"
Select "Specific resources"
Click on the "Specify resources" button and select your project's lib directory.
Check "Recursively include sub-folders"
Now go to the build options tab
Check "Allocate Console"
Check "Launch in background"
Check "Run the builder After a Clean"
Check "Run the builder During manual builds"
Check "Run the builder During auto builds"
Check "Specify working set of relevant resources"
Click on "Specify Resources"
Select your project's JNI directory and all files within.
Now click OK on the bottom.

The assumption here is that cygwin is installed to c:\cygwin, NDK is in c:\Android_NDK and your project is called "myapp". Change where appropriate.

What did you just do?! You made it so that any time you edit any files within your JNI directory and you save them, Eclipse will run the NDK Builder for you via CygwinADT to compile a new APK for you and YOU ARE GOOD TO GO!

This gravely fasted me up while working on my current project. I hope you can all benefit from it!

Simple Android Animation Application

Here is the example for simple android animation using <animation-list/> in  Drawable Folder in android.

Here is the java code for Simple Animation
<!----------------------------    --------------------------------------------->

public class AnimationSimpleActivity extends Activity {
    ImageView mImageView;
    
    private AnimationDrawable introDrawable;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mImageView=(ImageView)findViewById(R.id.animation);
        mImageView.setBackgroundResource(R.drawable.myanimation);
        introDrawable=(AnimationDrawable)mImageView.getBackground();
        mImageView.post(new Animator());
    }
    private long starttime,endtime;
    private class Animator implements Runnable {

    public void run() {
starttime=System.currentTimeMillis();
introDrawable.start();
Timer mTimer=new Timer();
mTimer.schedule(new ActivityChanger(), 3000);
}
}
    
    public class ActivityChanger extends TimerTask{


@Override
public void run() {
endtime = System.currentTimeMillis();
if(endtime-starttime >=1800){
AnimationSimpleActivity.this.finish();
Intent mIntent=new Intent(AnimationSimpleActivity.this, Activity2.class);
startActivity(mIntent);
}
}
   
    }

}

Below is the xml file for animation-list res/drawable/myanimation.xml


<?xml version="1.0" encoding="utf-8"?>
<animation-list
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:oneshot="true">
 <item  android:drawable="@drawable/f1" android:duration="200"/>
 <item  android:drawable="@drawable/f2" android:duration="200"/>
 <item  android:drawable="@drawable/f3" android:duration="200"/>

 <item  android:drawable="@drawable/f8" android:duration="200"/>
 <item  android:drawable="@drawable/f9" android:duration="200"/>  
   
</animation-list>

Here is the output:

How to get Resource Name In Android By Resource Id

Here i update my Custom GridView and i also add the ItemClickListen In It,And Here you can also find the how to get Resources Name By Passing It ID in android.

For that you have to First Refer My Last Post Of Custom GridView at here http://android-vogue.blogspot.com/2011/06/custom-gridview-in-android-with.html so now let see what i update in that is here below


First add the this line in OnCreate Method

mGridViewl.setOnItemClickListener(MyClickListener);

and after that add the


private OnItemClickListener MyClickListener=new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long lg) {

myarray.add(COUNTRIES[position]);
resourcename=getResourceNameByID(R.drawable.class,mThumbIds[position]);
Toast.makeText(Gridview.this, "Image Name is "+ resourcename, 34).show();
//Toast.makeText(Gridview.this, "Mood Has been selected ", Toast.LENGTH_SHORT).show();

//Log.v("log_tag", "the string is "  +  temp);

}
};

add above function in GridView Class

Now the most Important Part For Getting Resource Name Of Image By Passing ID of that Image we add following method in GridView Class


public String getResourceNameByID(Class<?> aClass,int ResourceID) throws IllegalArgumentException{

Field[]drawableFields =aClass.getFields();
for(Field f:drawableFields){
try{
if(ResourceID==f.getInt(null)){
return f.getName();
}
}
catch(Exception e){
e.printStackTrace();
}
}


throw new IllegalArgumentException();

}

Now you are ready to get Resource Name By Id of Resource.

Custom GridView In Android With ImageView and TextView

Every one want to do some thing with android ListView and GridView and Much More.
Here is the Example of Custom GridView in Which we have used ImageView and TextView below it.
Now One more thing that is this custom gridview can also done by the using View ,But i done it as shown in my code using Class Like what you want to put in grid just put it in gridview xml file and also make class ViewHolder as done by me in this tutorials .

Here below is my class for the GridView

public class Gridview extends Activity {
    GridView mGridViewl;
    //Context mContext = Gridview.this;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mGridViewl = (GridView) findViewById(R.id.gridview);
        mGridViewl.setAdapter(new EfficientAdapter(this));

    }
   
    private static class EfficientAdapter extends BaseAdapter{
        private LayoutInflater mLayoutInflater;
        public EfficientAdapter(Context context){
            mLayoutInflater=LayoutInflater.from(context);
        }
       
        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return mThumbIds.length;
        }

        @Override
        public Object getItem(int arg0) {
            // TODO Auto-generated method stub
            return arg0;
        }

        @Override
        public long getItemId(int arg0) {
            // TODO Auto-generated method stub
            return arg0;
        }

        @Override
        public View getView(int position, View converView, ViewGroup parent) {
            ViewHolder mVHolder;
            if(converView == null){
                converView=mLayoutInflater.inflate(R.layout.customgrid, parent, false);
                mVHolder=new ViewHolder();
                mVHolder.mImageView=(ImageView)converView.findViewById(R.id.imgview);
                mVHolder.mTextView=(TextView)converView.findViewById(R.id.text);
                mVHolder.mImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
                mVHolder.mImageView.setPadding(8,8,8,8);
                converView.setTag(mVHolder);
            }else{
                mVHolder=(ViewHolder)converView.getTag();
            }
            mVHolder.mImageView.setImageResource(mThumbIds[position]);
            mVHolder.mTextView.setText(COUNTRIES[position]);
           
            return converView;
        }
       
    }
   
    static class ViewHolder{
        ImageView mImageView;
        TextView mTextView;
    }

    static final String[] COUNTRIES = new String[] { "Afghanistan", "Albania",
            "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla",
            "Antarctica", "Antigua and Barbuda", "Argentina" };

   

    private static  Integer[] mThumbIds = { R.drawable.android,
            R.drawable.android1, R.drawable.android2,
            R.drawable.android3, R.drawable.android4,
            R.drawable.android5, R.drawable.android6, R.drawable.android7,
            R.drawable.android8, R.drawable.android9 };
}

and here is my main.xml  file for setcontentView(); in my activity

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"

Android Button Design and selector

For first The xml file for may main layout in android activity is following

main.xml
----------------------------------------------------------------------------------

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="@string/hello" />
<LinearLayout android:orientation="horizontal"
android:layout_width="wrap_content" android:layout_height="wrap_content">
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Done" android:id="@+id/donebtn"
android:padding="5dip" android:background="@drawable/button_view" />
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="back" android:id="@+id/backbtn"
android:padding="5dip" android:background="@drawable/button_view" />
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_width="wrap_content" android:layout_height="wrap_content">
<Button android:text="button_selector" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:background="@drawable/selector" />
</LinearLayout>
</LinearLayout>

-------------------------------------------------------------------------------------------------------------

After declare main xml file we will make 

<?xml version="1.0" encoding="UTF-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle">

<solid android:color="#453657" />

<stroke android:width="1dp" android:height="1dp"  android:color="#FFD40F"  />

<corners android:bottomLeftRadius="8dip"

android:topRightRadius="8dip" android:topLeftRadius="8dip"

android:bottomRightRadius="8dip" />

</shape>

this xml file in drawable folder of your project .

<solid/> this tag is for background color of shape

<stroke/> this tag is used for boarder of shape

<corners/> this tag is used for make the corner round at given value.

and now for changing on button clicked changes we define again new xml file like this below.

Selector.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@drawable/spinner_dropdown_background_down"

android:state_pressed="true" />

 

<item android:drawable="@drawable/spinner_dropdown_background_down" 

android:state_focused="true" />

<item android:drawable="@drawable/spinner_dropdown_background_up" />

</selector>

Why to choice android not iPhone or Other Phone Here the 10 Reasons

10 Things Android Does Better Than iPhone OS

When Android first debuted on the HTC Dream (also known as the G1) back in October of 2008, it was deemed an "iPhone Killer." While it didn't quite slay Apple's handset, it was the first step in a revolution against the tyrannous iPhone. The initial Android platform bested the iPhone OS on several levels, but lacked some key functionalities that the iPhone could provide. Since then, Android has grown - not only meeting all of the functionalities of the iPhone, but besting it in nearly all aspects from an extensive list of devices to a growing Android Marketplace. Here is our list of the top 10 things Android does better than the iPhone.

1: Android can Run Multiple Apps at the Same Time

Starting with version 1.0, Android has been able to run multiple applications at the same time regardless of whether they are system apps or apps from the Android Marketplace. The current version of iPhone OS does offer limited multitasking, but only allows native applications such as Mail, iPod and Phone to run in the background. Android users benefit greatly from this discrepancy, as they can receive notifications, listen to music, or even record GPS data without keeping the application open. Apple will try to level the playing field with iPhone OS 4, granting developers access to a small and limiting list of APIs that can run certain services in the background, but it's a long way from the true multitasking that Android has.

2:  Android Keeps Information Visible on Your Home Screen

One of the key features Android has is a customizable home screen keeps active widgets right at your fingertips, always accesible and always visible - without having to launch an application first. There are widgets for just about every app in the Android Marketplace from playing music to checking the weather and keeping up to date on Facebook. Meanwhile iPhone users are force to flip through their app list to locate and launch each app. If you wanted to check the forecast, for example, you would have to find the app, launch it, and then wait for it to load. With Android, all of that information can be displayed directly on your home screen, never more than a finger swipe away.

3: Android Has a Better App Market

It's true that Apple's App Store has over 180,000 applications, while the Android Marketplace has only just broken the 50,000 mark but Android's rapid growth and adoption give it the potential to catch up to the iPhone App Store. Android also has another advantage: a completely open market. Apple receives around 10,000 app submissions per week, yet many apps are overlooked because they appear too simple or denied because a similar app already exists. The Android Marketplace is driven entirely by its consumers, so the best app is the one that succeeds - not the first one to reach the market. In addition, the Android Marketplace doesn't censor its apps, so the possibilities are truly endless.

4: Android Gives You Better Notifications 

The iPhone has some trouble with notifications. Because it's restricted to pop-up notifications, it can only handle one at a time and because it lacks multitasking, applications must be open in order for them to make notifications. Android, on the other hand, has a convenient notification bar which displays an icon for every notification you have waiting. The notification bar can also be pulled downward to reveal more detail about each notification. Android also allows app developers to make notification details viewable from the lock screen, something the iPhone can only do with native applications.

5: Android Lets You Choose Your Hardware 

Apple users are encouraged to "Think Different" but when it comes to the actual hardware, they don't get much choice. You can pick the color, either black or white, and you get to choose between the 16GB or the pricier 32GB version. Other than that, you're stuck with the 3.5-inch, 320x480 pixel display, 256MB of RAM, and 600MHz processor. Because Android is an open platform, manufacturers have the freedom to pair it with any hardware they want, like the Nexus One (with 3.7-inch, 480x800 pixel display, 512MB of RAM, and 1GHz Snapdragon processor) or the Motorola Droid which has a physical keypad. Obviously, available selections will vary by carrier - speaking of which....

6: Android Lets You Choose Your Carrier

AT&T truly is the iPhone's weakest link. The iPhone's success turned the country's fastest 3G network into a staggering mess of dropped calls and dodgy data connections. If you lust after an iPhone and live in an area with poor AT&T coverage, you're stuck struggling with low signal quality, slow data speeds, and missed calls. Android devices are available on every major cellular carrier (although AT&T only offers a single, somewhat underpowered, Android phone). Verizon has the Motorola Droid, Droid Eris, and Droid Incredible to start. T-Mobile has the Nexus One, MyTouch 3G, Behold II, and will soon carry the MyTouch Slide. And Sprint has the Hero, Moment, and plans for the very promising Evo 4G. No matter where you live, Android lets you pick the carrier that's best for you.

7: Android Lets You Install Custom ROMs

The iPhone can be Jailbroken for some additional functionality, like installing apps that aren't available in the App Store, but the overall experience is the same. You're still stuck with the same exact interface. Similar to the Jailbreaking movement, Android has a small community dedicated to building custom ROMs for Android devices. Not only do Custom ROMs bring the same functionality Jailbreaking does, but they also bring an additional level of customization to your phone. There are ROMs that port custom UIs from one device to another. Other ROMs strip down bulky features and optimize for speed. With Android, nothing is out of reach.

8: Android Lets You Change Your Settings Faster

Smartphones have been gaining more and more functionality over the past few years: Wi-Fi, GPS, 4G, Bluetooth, etc. While these are all great and necessary additions, they have very adverse affects on battery life. In attempts to counter poor battery life, users have taken to toggling system settings like turning on Wi-Fi or 3G on only when they are needed. iPhone users are stuck digging around in the system settings every time they want to use the internet or a Bluetooth device. Android lets you use widgets to manage your settings directly from your home screen - and for those lesser-used settings that might not have dedicated widgets, you can also create shortcuts on your home screen to take you directly to the setting you want to change.

9: Android Does Google and Social Integration

With Smartphones giving us constant connectivity, it's not surprising that the majority of our computerized lives are moving online. We have email for our messages, Flickr for our photos, Google Docs for our documents, and Facebook and Twitter for our social lives. Android offers the ability to integrate all of this natively. Your Gmail account can be automatically synchronized with your phone. Photos taken with your phone can be automatically uploaded to Flickr. Your phone can even be linked to your Facebook account and can sync your phone contacts with your Facebook friends - complete with profile images, email addresses, and phone numbers. The iPhone can do this only through use of third party apps, and is nowhere near as seamless to use as the Android alternative.

10: Android Gives You More Options to Fit Your Budget 

If you've ever thought about buying an iPhone, you have probably noticed the price tag. The older iPhone 3G costs $99 with a two-year commitment and performs sluggishly with the latest OS updates when compared to the 3GS (which will run you a whopping $199 with two-year agreement). Because Android is an open source platform, it is very cost effective to implement which means savings for the end user. Every major cellular carrier (except for AT&T) has at least one Android phone available free with two-year agreement. Of course these are lower end Android devices, but they are still comparable in performance to the iPhone 3GS. The most expensive Android phones (which significantly outperform the iPhone 3GS) are  $199 with two-year contract.
