Camera switch bug crash - Null pointer exception showTitle

[GuillemRoca]

I've found a weird bug while switching camera.

Steps to reproduce: default camera app was open in the background 1.open the sample app with TED initialized with custom string title and choose capture camera 2.while the sample camera is open change apps for default camera 4.change back to sample camera and make the photo 5.observe

Here is the stacktrace:

@joxad same here. Did you figure it out why? or did you find any solution for it?

[ParkSangGwon]

@GuillemRoca @iammert Can you upload your sample project code? I will test and check error.

[iammert]

@ParkSangGwon It is not reproducible on my side. So I don't think sample code will help you because my app is already used by thousands of people and just %1 of users are crashing. Anyway, here is the sample code from my project.

TedBottomPicker bottomSheetDialogFragment = new TedBottomPicker.Builder(AskQuestionActivity.this)
                                .setOnImageSelectedListener(uri -> viewModel.startCropActivity(uri))
                                .setPeekHeight(getResources().getDisplayMetrics().heightPixels / 2)
                                .create();
                        bottomSheetDialogFragment.show(getSupportFragmentManager());

[xarmykwon]

저도 이거 발생하네요.

제폰 노트5는 잘되는데

갤럭시s4 5.0.1버전은

Caused by: java.lang.NullPointerException: Attempt to read from field 'boolean gun0912.tedbottompicker.TedBottomPicker$Builder.showTitle' on a null object reference

널포인트 떠버리네요

사진 직접 촬영시 발생합니다.

잡히지가 않네요 boolean값인데 . 메모리 뻑나서 초기화되었나 싶어서 라지힙 트루도 줘보고, 사진 촬영의 화질을 낮춘걸로 해도 마찬가지네용 ㅎㅎ

I found a solution related to #43 that can apply to this issue.
