what is NotificationActivity ?

[Serobegi]

public class NotificationActivity extends Activity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      // If this activity is the root activity of the task, the app is not running
      if (isTaskRoot()) {
         // Start the app before finishing
         final Intent parentIntent = new Intent(this, FeaturesActivity.class);
         parentIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
         final Intent startAppIntent = new Intent(this, DfuActivity.class);
         startAppIntent.putExtras(getIntent().getExtras());
         startActivities(new Intent[] { parentIntent, startAppIntent });
      }

      // Now finish, which will drop the user in to the activity that was at the top
      //  of the task stack
      finish();
   }
}


The code above is the sample code provided by GitHub.
But I don't use what is called FeaturesActivity. So what class should I put there?
Below is my code. How would you like to modify it?

public class NotificationActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // If this activity is the root activity of the task, the app is not running
        if (isTaskRoot()) {
            // Start the app before finishing

            final Intent intent = new Intent(this, OTA.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.putExtras(getIntent().getExtras()); // copy all extras
            startActivity(intent);
        }

        // Now finish, which will drop you to the activity at which you were at the top of the task stack
        finish();
    }
}

Hello,

The code above is the sample code provided by GitHub.
But I don't use what is called FeaturesActivity. So what class should I put there?
Below is my code. How would you like to modify it?

Have you seen the notificationActivity's description in the Android DFU Library documentation?
Furthermore, could you elaborate on what you would like the application to do - why are you changing this part - what is the desired behavior from the code you have written in place of the original code?

Looking forward to resolving this issue together,

Best regards,
Karl

Thanks for the answer.

FeaturesActivity was created by referring to Toolbox github.

My goal is to simply OTA a specified file in a set directory.

The code has been modified in the last two days and is written as follows. But still, I am not sure why NotificationActivity is used. What should the class call by Intent of NotificationActivity class contain?

The program I am writing is performed by starting MainActivity -> OTA Activity is called -> Work progress -> Returning MainActivity.

My English was wrong, so I got help from a Google translator. I will wait for your answer. I want to say thank you again.

// Try to create sample files
if (FileHelper.newSamplesAvailable(this)) {
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
        Log.d("FileHelper ", "createSamples");
        FileHelper.createSamples(this);
    } else {
        ActivityCompat.requestPermissions(OTA.this, new String[]{Manifest.permission.READ_CONTACTS}, MY_PERMISSIONS_WRITE_EXTERNAL_STORAGE);
    }
}
