How to avoid black screen while invoking another activity in android?

Please check the flags you are setting in your intent.

If you have a finish(); or FLAG_ACTIVITY_CLEAR_TASK - a blank screen may show up on

 pre ICS devices as the current activity has been cleared before another activity is started.

code:

Intent intent = new Intent(getApplicationContext(), Activity.class);

intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(intent);

overridePendingTransition (0, 0);
