App opens and closes immediately, without crashing

Question

The app opens briefly to a white screen and closes almost immediately after. I would say the time frame is about 1-2 seconds.

I have tried uninstalling the app, clearing the cache, etc..

When debugging the app I do not see anything that stands out. Here is the stacktrace involved during app opening/closing.

I tried placing a breakpoint within the OnCreate() of MainActivity and it does not ever get hit. It almost seems as if it doesn't get to the MainActivity.

What could cause something of this nature?

UPDATE:

The app initially started with this type of behavior after I tried converting PictureEditActivity from a Fragment to an Activity. I modified code in both FeedActivity, and PictureEditActivity to keep the functionality.

Since the error I have reverted back to the previous code before the error, but the behavior still persists.

RESOLVED

After testing the app on another device it resulted in an error. I traced this error back to a line of code in another portion of my app involving ParseDB and registering multiple subclasses.

Answer 1

**final solution **

open your logcat panel for your device to see where the error comes from

for me it was MainThread. it took my day to figured out.

Answer 2

Here is the code that was causing an issue.

public class InitializeApplication extends Application {

    static final String TAG = "MyApp";

    @Override
    public void onCreate() {
        super.onCreate();

        ParseObject.registerSubclass(Receipt.class);
        ParseObject.registerSubclass(PUpload.class);  ///<<< ISSUE

        Parse.initialize(this, "XXXXXXXXXXXXXXXXXXXXXXXXXX",
                "XXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
    }
}

After commenting out that line of code there are no more errors being thrown.

FULL FIX

The error was due to an incomplete constructor within my ParseObject PUpload class. I corrected the constructor and now all is well.

Answer 3

if ((currentUser != null)) {


            showPrimaryActivity();
            finish();         //remove this
        }

Remove the finish() from your code from the onCreate(),it is making your app to close down.....

Answer 4

may be that reason change every intent have this to MainActivity.this and add finish(); to the method showPrimaryActivity() make sure finish dont close app when it just open

 private void showPrimaryActivity() {
        Intent intent = new Intent(MainActivity.this, NavigationActivity.class);
        startActivity(intent);
      finish();
         }    

    Intent intent1 = new Intent(MainActivity.this, SignUpActivity.class);
            startActivity(intent1);
