Resume activity in Android-ThrowExceptions

Exception or error:

I have an app with 3 activities.

I have the main activity. This calls the second activity, which then calls the third activity. I want return to the main activity without entering the onCreate.

This is the code for the third activity:

startActivity(new Intent(TerceraActiviry.this, Main.class));
How to solve:

If your Activity is still running, this code will bring it to the front without entering onCreate

Intent openMainActivity = new Intent(TerceraActiviry.this, Main.class);
startActivityIfNeeded(openMainActivity, 0);


in order to get back to previous Activity you have to finish the visible one, use this:


If the activity was started for a result, you should give a result then, like this:

Intent intent = new Intent();
intent.putExtra(KEY_RESPONSE, responseData);
setResult(RESULT_OK, intent);

And you should catch the result on the caller Activity using:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

  switch (requestCode) {
    // Test for the code you have used to start the Activity

Hope it helps,


You startActivityForResult instead of startActivity.

refer the android dev for more info here.


The launch mode flag you want is clearTop. This will go back to the previous instance of the main activity and clear the second and third activity off the activity stack. For example, to do this from the code:

Intent intent = new Intent(TerceraActiviry.this, Main.class));
