BackButton not working properly

Question

i have application which starts with an animation and then we move to another(P1 )activity. But if i press back button from from p1 then i go back to the animation(LoadActivity) and if i press back button now then i should go to application manager but instead i go back to P1 activity like there is a loop from p1 to LoadActivity and from LoadActivity to P1

LoadActivity.java

public class LoadActivity extends Activity  {
boolean doubleBackToExitPressedOnce=false;
    ImageView im;
    Animation rotate;
    private Handler mHandler;
    private Runnable mRunnable;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.load);
        im = (ImageView) findViewById(R.id.load_icon);
        rotate = AnimationUtils.loadAnimation(getApplicationContext(),
                R.anim.load_page);
        rotate.setInterpolator(new LinearInterpolator());
        im.startAnimation(rotate);

    mHandler = new Handler();
    mRunnable = new Runnable() {
        @Override
        public void run() {
            Intent nextPageIntent = new Intent(getApplicationContext(),
                    P1.class);
            startActivity(nextPageIntent);

        }
    };

    mHandler.postDelayed(mRunnable, 3000);
}

    public void onBackPressed() {
         Toast.makeText(this, "Please click BACK again to exit", Toast.LENGTH_SHORT).show();
        mHandler.removeCallbacksAndMessages(mRunnable);
        android.os.Process.killProcess(android.os.Process.myPid());


        }

P1.java

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.p1);
        int currentOrientation = getResources().getConfiguration().orientation;
        if (currentOrientation == Configuration.ORIENTATION_LANDSCAPE) {

             context=this;
           LayoutInflater inflater = LayoutInflater.from(context);

            View view = inflater.inflate(R.layout.lay_inflate_land,null);
            RelativeLayout f=(RelativeLayout)findViewById(R.id.iv_p1);
            f.addView(view);
        }
        else {

             context=this;
           LayoutInflater inflater = LayoutInflater.from(context);

            View view = inflater.inflate(R.layout.lay_inflate,null);
            RelativeLayout f=(RelativeLayout)findViewById(R.id.iv_p1);
            f.addView(view);
        }



        button = (Button)findViewById(R.id.let_start_p2);



        button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent nextPageIntent = new Intent(getApplicationContext(), P2.class);
                startActivity(nextPageIntent);
            }
        });


    }
    @Override
    public void onBackPressed() {
        Intent nextPageIntent = new Intent(getApplicationContext(), LoadActivity.class);
        startActivity(nextPageIntent);
        }

try to finish your activity in onBackPressed() after call LoadActivity. — Haresh Chhelana, Aug 28 '14 at 04:46

Try to replace this code :

@Override
public void onBackPressed() {
  Intent nextPageIntent = new Intent(getApplicationContext(), LoadActivity.class);
  startActivity(nextPageIntent);
  finish();
}

try this, http://stackoverflow.com/questions/8430805/android-clicking-twice-the-back-button-to-exit-activity – SathishKumar Aug 28 '14 at 04:58
can you please let me know why again start P1 from LoadActivity in handler ? – Haresh Chhelana Aug 28 '14 at 05:00
Bcoz i have to go to P1 once the animation is finished that is user requirement – Pallavi Choudhary Aug 28 '14 at 05:13
No Sathish the problem still persist – Pallavi Choudhary Aug 28 '14 at 05:14
Okay so when your animation is over you again goto P1 and back pressed again came to LoadActivity so my question when you exit from LoadActivity ? – Haresh Chhelana Aug 28 '14 at 05:19
then according to requirement the application is be killed but according to my code it is restarting LoadActivity and then if backbutton is pressed then the application is finished so in a nutshell we need to press backbutton twice in order to exit the application when in LoadActivity – Pallavi Choudhary Aug 28 '14 at 05:28
can you please override onBackPressed() in LoadActvity and first line mHandler.removeCallbacks(mRunnable); and second line super.onBackPressed(); and let me is it working or not ? – Haresh Chhelana Aug 28 '14 at 05:32
can you please post code in you question what have you done ? – Haresh Chhelana Aug 28 '14 at 06:45
