How to use IntentCompat.makeRestartActivityTask()?

Question

I\'m trying to implement a button that will result in my app going back to the first activity and acting as if it was (almost) restarted all over. This code

Answer 1

This is how I'm using IntentCompat

    Intent intentToBeNewRoot = new Intent(this, MainActivity.class);
    ComponentName cn = intentToBeNewRoot.getComponent();

    Intent mainIntent = IntentCompat.makeRestartActivityTask(cn);

    startActivity(mainIntent);

This effectively replaces my no-longer-wanted task root with MainActivity. It works in Gingerbeard and ICS. I haven't seen the "is an undefined symbol" message.

Update

Google has removed the method IntentCompat.makeRestartActivityTask() in current support library versions. Instead, you can just use the plain Android API:

ComponentName cn = intent.getComponent();
Intent.makeRestartActivityTask(cn);

I hope this can save someone time searching for alternatives ;)

Answer 3

IntentCompat is deprecated which is may be deleted, but Intent class this static method

Intent mainIntent = Intent.makeRestartActivityTask(cn);

So just use the above statement.
