Android Camera : data intent returns null

Question

I have an android application which contains multiple activities.

In one of them I\'m using a button which will call the device camera :

public void         


        

Answer 1

I´ve had experienced this problem, the intent is not null but the information sent via this intent is not received in onActionActivit()

This is a better solution using getContentResolver() :

    private Uri imageUri;
    private ImageView myImageView;
    private Bitmap thumbnail;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

      ...
      ...    
      ...
      myImageview = (ImageView) findViewById(R.id.pic); 

      values = new ContentValues();
      values.put(MediaStore.Images.Media.TITLE, "MyPicture");
      values.put(MediaStore.Images.Media.DESCRIPTION, "Photo taken on " + System.currentTimeMillis());
      imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
      Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
      intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
      startActivityForResult(intent, PICTURE_RESULT);

  }

the onActivityResult() get a bitmap stored by getContentResolver() :

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == REQUEST_CODE_TAKE_PHOTO && resultCode == RESULT_OK) {

            Bitmap bitmap;
            try {
                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri);
                myImageView.setImageBitmap(bitmap);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }

        }
    }
