Question

I’m new in android and working on an app that captures photo by camera and set it as wallpaper.Here’s the code :

public class camera extends Activity implements  View.OnClickListener  {


private ImageButton imgb;
private ImageView imgv;
private Button b;
Intent i;
static int cameraData =0;
Bitmap bmp;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.image);

    cleaning();
    InputStream is=getResources().openRawResource(R.drawable.ic_launcher);
    bmp=BitmapFactory.decodeStream(is);


}

private void cleaning() {
    imgb=(ImageButton) findViewById(R.id.imgbutt);
    imgv=(ImageView) findViewById(R.id.iv);
    b=(Button) findViewById(R.id.butt);
    imgb.setOnClickListener(this);
    b.setOnClickListener(this);


}

@Override
public void onClick(View arg0) {

    switch(arg0.getId()){
    case R.id.imgbutt:
    i=new Intent (android.provider.MediaStore.ACTION_IMAGE_CAPTURE);    
    startActivityForResult(i, cameraData);

        break;

    case R.id.butt :
        try {
            getApplicationContext().setWallpaper(bmp);
        } catch (IOException e) {
            e.printStackTrace();
        }


        break;




    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(resultCode==RESULT_OK){

    Bundle extras=data.getExtras();

    bmp=(Bitmap) extras.get("data");
    imgv.setImageBitmap(bmp);
}
}

}

The problem is every time I hit “take pic” button I get an error say:
the application has stopped unexpectedly

Some tips from when I have to troubleshoot is just simply using logcat.
