Android Back Button to specific activity

When I click the back button Android goes to the previous activity. Is it possible to set for every activity a custom (back) activity or to set the back button to the home menue of the app?

Help or hints would be great :)

How do I go back to previous activity on android?

Android activities are stored in the activity stack. Going back to a previous activity could mean two things. You opened the new activity from another activity with startActivityForResult. In that case you can just call the finishActivity() function from your code and it'll take you back to the previous activity.

You will have to override onBackPressed() from your activity:

@Override
public void onBackPressed()
{
    super.onBackPressed(); 
    startActivity(new Intent(ThisActivity.this, NextActivity.class));
    finish();

}
