Go back to the First/Main activity without reloading it

Question

I am developing an android app. I need to call my MainActivity without reloading it as it has huge amount of data fetch from internet.

Suppose, I am on third activity now and I want to go back to MainActivity.

If I use:

Intent i = new Intent(Third.this,Main.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);

it will load MainActivity but I don't want to reload it. like from Second Activity I call finish() and it does exactly want i need.

Answer 1

This is how to do it:

Intent i = new Intent(this, MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(i);

Answer 2

metntion it in your AndroidManifest.xml file

<activity android:name=".MyActivity"

              android:configChanges="keyboardHidden|orientation">

do nothing inside the method onResume() and onstart() when coming back to this activity

and try intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); instead of addFlags() method
