Java how to disable coming back to activity android studio

To disable the ability to return to an activity in Android, you can set the android:noHistory attribute to true in the activity's AndroidManifest.xml file. This attribute specifies that the activity should not be kept in the activity stack and should be finished when the user navigates away from it.

Here's an example of how to set the android:noHistory attribute in the AndroidManifest.xml file:

<activity
  android:name=".MainActivity"
  android:noHistory="true"
  android:label="@string/app_name">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

Alternatively, you can use the finish() method to finish the activity when the user navigates away from it. This method removes the activity from the activity stack and destroys it.

Here's an example of how to use the finish() method to disable the ability to return to an activity:

@Override
protected void onCreate(Bundle savedInstanceState) {
  // ...
}

@Override
public void onBackPressed() {
  // Disable the ability to return to the activity
  finish();
}

Note that setting the android:noHistory attribute or calling the finish() method does not completely destroy the activity. It only marks the activity as finished and removes it from the activity stack. The system may still keep the activity in memory if it is part of a back stack of fragments. To completely destroy an activity and release all its resources, you can use the onDestroy() method, which is called when the activity is being destroyed.
