Facebook Login Button crashing app without error message

Answer 09/07/2018 Developer FAQ 1

This issue suddenly popped up this morning after working great for weeks.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_login);

    callbackManager = CallbackManager.Factory.create();
    LoginButton loginButton = (LoginButton) findViewById(R.id.authButton);
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            Log.d("Facebook Login Status", "success!");
        }

        @Override
        public void onCancel() {
            Log.d("Facebook Login Status", "Canceled!");
        }

        @Override
        public void onError(FacebookException exception) {
            Log.d("Facebook Login Status", "Failed!");
        }


    });

}

Somewhere in there, the app crashes. None of the callback methods are run, and nothing is printed to logcat. I just see a loading spinner for a split second and then the app force closes with no message.

Edit:

I did find this log actually, but I don't know what it means.

Answer1:

The same was happening to me, so I started from scratch with another Activity and slowly duplicated the new activity till it matched the one that was breaking. In short, it was nothing to do with the Activity but the Android Manifest.

In my Android Manifest, I had android:noHistory="true" on my LoginActivity which was crashing my app. Once I removed it then it worked again.
