Camera null pointer in android fragment?

Question

There's lots of questions on the same topic, however none of them provided me an answer that I needed. I've tried a lot of solutions,and none of them is working for me so far. I stuck while trying to take picture in my fragment using Android's Camera and take picture from gallery, it because I always get NullPointerException. this is my code while user click button for capture or taking picture from galery:

capture_dp.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                intent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION, ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, setImageUri());
                startActivityForResult(intent, TAKE_PHOTO_CODE);
                }
        });
add_galery_dp[counter2].setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                   Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                   startActivityForResult(i,
                            PICK_FROM_GALLERY);
                    }
        });

this my method :

 @Override
     public void onActivityResult(int requestCode, int resultCode, Intent data) {

         super.onActivityResult(requestCode, resultCode, data);
                    if (requestCode == TAKE_PHOTO_CODE && data != null) {
                            selectedImagePath = getImagePath();
                            nama_foto[counter]=new File(path1,"foto"+GetTime.getCurrentDate("yyyyMMddhhmmss")+".jpg");
                            FileOutputStream fos = null;
                            if(! nama_foto[counter].exists())   
                            {
                                try {
                                    Bitmap bitmap= rotateBitmap(selectedImagePath);
        //                           nama_foto[counter].createNewFile();
        //                          copyFile(new File(selectedImagePath),  nama_foto[counter]); //untuk copy file dari selected image path ke nama_foto
                                    fos = new FileOutputStream( nama_foto[counter]);
                                    bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos);
                                    fos.flush();
                                    fos.close();
        //                            MediaStore.Images.Media.insertImage(getActivity().getContentResolver(), bitmap, "Screen", "screen");

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 actually camera had write the captured file in that path.

For further information you can follow this, this and this

I have try your answer, but intent data still null T.T – Menma Nov 05 '15 at 09:46
there's no force close but the capture's image still not show in ImageView, when I debug it, intent data still nul T.T – Menma Nov 05 '15 at 10:02
You have provided the image path right when the intent starts check were there is an image when capture photo. – Anoop M Maddasseri Nov 05 '15 at 10:04
how to check if there is an image when capture photo? – Menma Nov 05 '15 at 10:13
How setImageUri() returning the path..there you have to check. – Anoop M Maddasseri Nov 05 '15 at 10:18
`setImageUri()` returning the true path.. now I confure why my Intent Data still null – Menma Nov 05 '15 at 10:27
I mean go to the path in device..check image is saving there after capturing. – Anoop M Maddasseri Nov 05 '15 at 10:29
Image is saving after capturing, but intent always null... I have no Idea why this is happen to my application – Menma Nov 06 '15 at 04:15
