onActivityResult RESULT_CODE always 0 (cancel)

Question

Another weird question. Always getting RESULT_CANCELLED (that's a problem) while working with camera via intent. More relevant context:

I assign setOnClickListener to ImageView in activities' onCreate:

this.imSnapshot.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, getImageUri());
        startActivityForResult(cameraIntent, CAMERA_REQUEST);
    }
});

Code of getImageUri method:

private Uri getImageUri() {
    ContextWrapper cw = new ContextWrapper(this);
    File dir = cw.getDir("dcim", Context.MODE_PRIVATE);
    File file = new File(dir, UUID.randomUUID().toString()+".png");
    Uri imgUri = Uri.fromFile(file);
    Log.d("DetailsModify.getImageUri", imgUri.toString());
    return imgUri;
}

Here is onActivityResult (log line always return 0):

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_REQUEST) {
        Log.d("DetailsModify", "onActivityResult code " + resultCode);
        if (resultCode == RESULT_OK) {

UPDATE: the error was filtered by IDE so I did not notice it originally:

Answer 1

As I have not received any better solution to my question, sharing what I got on my own. I made my problem solved by adding dir.setWritable(true, false) to method below, tested on API10:

private Uri getImageUri() {
    ContextWrapper cw = new ContextWrapper(this);
    File dir = cw.getDir("dcim", Context.MODE_PRIVATE);
    dir.setWritable(true, false);
    File file = new File(dir, UUID.randomUUID().toString()+".png");
    Uri imgUri = Uri.fromFile(file);
    Log.d("DetailsModify.getImageUri", imgUri.toString());
    return imgUri;
}

What it does is it sets permissions allowing Camera to write to application's private location (more info at http://developer.android.com/reference/java/io/File.html#setWritable%28boolean,%20boolean%29). I hope that helps someone.
