I am trying to upload an image (captured by the camera) using the Facebook Dialog in the Facebook SDK. But it crashes after entering facebook. I can not solve the problem.
Here is my code
protected void postStatus() { byte[] data = null; try { ContentResolver cr = getContentResolver(); InputStream fis = cr.openInputStream(MyCarDealActivity.imageUri); Bitmap bi = BitmapFactory.decodeStream(fis); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bi.compress(Bitmap.CompressFormat.JPEG, 100, baos); data = baos.toByteArray(); } catch (FileNotFoundException e) { e.printStackTrace(); } Bundle parameters = new Bundle(); parameters.putString("method", "photos.upload"); parameters.putByteArray("picture", data); parameters.putString("caption", "Hello"); facebook.dialog(FacebookScreen.this, "me/photos", parameters, new DialogListener() { @Override public void onCancel() { } @Override public void onComplete(Bundle values) { Toast.makeText(FacebookScreen.this, "Published", Toast.LENGTH_LONG).show(); finish(); } @Override public void onError(DialogError e) { Toast.makeText(FacebookScreen.this, "Error :" + e.getLocalizedMessage(), Toast.LENGTH_LONG).show(); finish(); } @Override public void onFacebookError(FacebookError e) { Toast.makeText(FacebookScreen.this, "Error :" + e.getLocalizedMessage(), Toast.LENGTH_LONG).show(); finish(); } }); }
Here is the error log
