Capture vom Kamera funktioniert nicht mehr on Android 7.0

  • Hallo, bitteum eine Hilfe !


    mein code funktioniert unter android 4 bis 6
    Nachdem ich my galaxy s6 auf Android 7.0 aktualisiert have, funktioniert my code nicht mehr



    private void Capture_Cam() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, 113);


    }
    - - -


    } else if (requestCode == 113) {
    if (resultCode == RESULT_OK) { // from camera
    picUri = data.getData();
    try {
    bitmap2 = MediaStore.Images.Media.getBitmap(this.getContentResolver(), picUri); // Error hier bei dieser Linie
    bitmap_width_org = bitmap2.getWidth();
    bitmap_height_org = bitmap2.getHeight();
    } catch (IOException e) {
    e.printStackTrace();
    }
    performCrop();
    }
    } else if (requestCode == PIC_CROP) {
    - - -



    Fehler lautet :
    java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=113, result=-1, data=Intent { act=inline-data flg=0x1 launchParam=MultiScreenLaunchParams { mDisplayId=0 mFlags=0 } (has extras) }} to activity {---.Activity2}: java.lang.NullPointerException: uri

    Ohne Login leider keine Infos.
    Könntest du die Lösung rüber kopieren?
    Würde das auch gerne lesen, mir aber keinen neuen Account machen.

    Kann Spuren von persönlicher Meinung, Sarkasmus und Lakritz enthalten. Einzelne Wörter nicht für den Verzehr geeignet. Ungelesen mindestens haltbar bis: suche bei Google

  • Sicher das bei "picUri = data.getData()" die picUri nicht null ist? Am besten mal im Debugger prüfen. Poste doch mal den Code wo du die URI an den Intent übergibst.


    Normalerweise gibt "picUri = data.getData()" ein Thumbnail zurück wie du in der Android Doku nachlesen kannst

    Code
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            Bundle extras = data.getExtras();
            Bitmap imageBitmap = (Bitmap) extras.get("data");
            mImageView.setImageBitmap(imageBitmap);
        }
    }



    Hier wird eine URI an den Intent übergeben

    Code
    Uri photoURI = FileProvider.getUriForFile(this, com.example.android.fileprovider", photoFile);
    
    
    takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
    startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
  • ie Kamera startet
    Bild wird aufgenommen
    aber wenn ich klicke wieder auf OK um das Bid zu schneiden, dann bekomme ich schwarzen Bildschirm
    also d.h. OnResult liefert kein korekte uri für schneide-Funktion, denke ich oder ?

  • Ich habe den code getestet, es funktioniert aber ich möchte das Bild schneiden
    hier ist der code complet von dem Beispiel dort
    kann jemand die Crop funktion drin einbauen ?
