Question

Unable to extract text from image after capturing the image through camera.In logcat i'm getting some exceptions (from CropImage.activity(data.getData())).Below is the logcat with some exceptions and java code.

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.net.Uri android.content.Intent.getData()' on a null object reference
        at com.example.nabil.textocr.MainActivity.onActivityResult(MainActivity.java:172)

Java code for the camera

dialog.setItems(items, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                if (which==0){
                   if (!checkCameraPermission()){
                       requestCameraPermission();
                   }else {
                       pickCamera();
                   }
                }

 private void pickCamera() {
        ContentValues values=new ContentValues();
        values.put(MediaStore.Images.Media.TITLE,"NewPic");
        values.put(MediaStore.Images.Media.DESCRIPTION,"Image to text");
        image_uri=getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,values);
        Intent cameraintent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        cameraintent.putExtra(MediaStore.EXTRA_OUTPUT,image_uri);
        startActivityForResult(cameraintent,IMAGE_PICK_GALLERY_CODE);
    }

 @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        if (resultCode==RESULT_OK){
            if (requestCode==IMAGE_PICK_GALLERY_CODE){
                CropImage.activity(data.getData())
                        .setGuidelines(CropImageView.Guidelines.ON)
                        .start(this);

            }

`onActivityResult()` could be called as a result of some other `startActivityForResult()` call. The `requestCode` can help you ensure your call to `data.getData()` only happens when `startActivityForResult()` is called from `pickCamera()`. To see how, check out https://stackoverflow.com/a/14148838/2848676. If some other intent is causing `onActivityResult()` to be called, a `null` value of `data` could valid in that case. So you want to filter it out using `requestCode`. I'm not sure that will solve your problem, but it could at least rule out one possible cause. — Michael Osofsky, Jan 10 '19 at 19:29

The default Android camera application returns a non-null intent only when passing back a thumbnail in the returned Intent. If you pass EXTRA_OUTPUT with a URI to write to, it will return a null intent and the picture is in the URI that you passed in
