                     at android.app.ActivityThread.deliverResults(ActivityThread.java:5000)

Here is my code:

 static final int REQUEST_TAKE_PHOTO = 1;
 private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = image.getAbsolutePath();
    return image;
}

private void dispatchTakePictureIntent() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File
        }
        // Continue only if the File was successfully created
        if (photoFile != null) {
            Uri photoURI = FileProvider.getUriForFile(this,
                    "com.example.android.fileprovider",
                    photoFile);
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
            startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
        }
    }
}

And here is my StartActivityForResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
        imgBitmap = (Bitmap) data.getExtras().get("data");
        img.setImageBitmap(imgBitmap);
        Toast.makeText(getApplicationContext(),mCurrentPhotoPath,Toast.LENGTH_SHORT);
    }
}

So this is what I did before error: 1.Opened my camera intent 2.Took the picture 3.I pressed OK and i got that the data from result is empty error

I followed this documentation from google: https://developer.android.com/training/camera/photobasics.html#TaskGallery So can you guys tell me what i did wrong? Thanks in advance

Please stop deleting questions. We covered your problem already, in a question that you have since deleted. There is no `"data"` extra when you use `EXTRA_OUTPUT`. Instead, the photo will be written to the location that you specified in `EXTRA_OUTPUT`. Go look for that file. — CommonsWare, Jan 20 '18 at 15:52

If you pass the extra parameter MediaStore.EXTRA_OUTPUT with the camera intent then camera activity will write the captured image to that path and it will not return the bitmap in the onActivityResult method.

If you will check the path which you are passing then you will know that actual camera had written the captured file in that path.

So you need some changes in your code

To start the camera activity use

Intent cameraIntent=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
startActivityForResult(cameraIntent, CAMERA_REQUEST);

After capturing the image you will get captured image in the bitmap format in onActivityResult method. Now when you get the bitmap use it as you want to.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
   if (requestCode == 1) {  
        Bitmap bmp = intent.getExtras().get("data");
        //Use the bitmap as you want to
   }  
}

Note: Here bitmap object consists of thumb image, it will not have a full resolution image
