Android: Black Screen between Activity

Question

When I go one activity to another activity , between the transaction a Black screen is come for some seconds. I properly finish the activity before calling startActv

Answer 1

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

To avoid this black screen you have to add one line in intent

overridePendingTransition (0, 0);

Example(kotlin):

val intent = Intent(applicationContext, MainActivity::class.java)
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
startActivity(intent)
overridePendingTransition (0, 0)

Example(Java):

Intent intent = new Intent(getApplicationContext(), MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
overridePendingTransition (0, 0);
