[FIXED] Pressing Back button to finish a series of Activities

Issue

Suppose there is a button on the homepage of my Activity.

When I press this button, it goes to Activity A

in Activity A , it automatically goes to Activity B using Intents and startActivityForResult();

in Activity B , it automatically goes to Activity C using Intents and startActivityForResul();

in Activity B, it automatically starts the intent to go BarCode scanner activity and get results.

My problem is when I press a button to return to my home page, it requires pressing 4 times go back to my homepage

If I want to press back to my homepage at one time, how to finish such series of activities?

Solution

Don't Use/override onBackPressed() anywhere in your program

just add the following method in the parent activity such as Activity A and B

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

Start Activity on your onClick method using

    startActivityForResult(intentName, 0);

In Child Activity you use/override onStop() method

    @Override
protected void onStop()
{
    super.onStop();

}
