Unwanted Duplicated Activity

There is a code that sends an int 'a' from the main activity to activity B. It also starts activity B with the fade animations. However, this code creates 2 of the same activity B'

Solution 1:

You are starting the second activity twice. Remove the following line from your code and move overridePendingTransition after you use the intent to start the activity:

startActivity(newIntent(MainActivity.this, Differentiate.class));

Solution 2:

Hey just remove this line from code:

startActivity(newIntent(MainActivity.this, Differentiate.class)); 

Rest is fine in your code.

Solution 3:

That's because you are starting Activity B twice!

you should remove this part of your code:

startActivity(newIntent(MainActivity.this, Differentiate.class));
