Android App crashes after choosing image from gallery

Question

Im using the following code to let the user select an image from his gallery. But after selecting an img the app crashes.

Intent i = new Intent(
        Intent.ACTION_PICK,
        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(i, RESULT_LOAD_IMAGE);

Heres the logcat of the crash:

Heres the onActivityResult, in which the exception occurs.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
            && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);

        cursor.close();

        ImageView imageView = (ImageView) findViewById(R.id.chosenpictureview);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

        filepath = picturePath;
        thread.setPathToOurFile(picturePath);


    }

}

Also, post the pertinent portions of your `onActivityResult()` function. — David Manpearl, Mar 31 '13 at 22:54
Where do you declare `thread`? Can you post that code as well. — Tushar, Mar 31 '13 at 23:00
Oh thanks now it works. I commented that out for testing and forgot about that — user2147674, Mar 31 '13 at 23:03
query can return null on error (such as the URI not existing). My bet is it returned null. You aren't checking for that before calling moveToFirst. — Gabe Sechan, Mar 31 '13 at 23:00
OP's saying the NPE happens on `thread.setPathToOurFile(picturePath);`. — Tushar, Mar 31 '13 at 23:01

In onActivityResult() you can also open the selected image from the Uri selectedImage directly (that you got with getData()), instead of using the MediaStore query.

Camera or Gallery:

If you wish to allow the user to select from either the gallery or from the camera, make sure to view this post: Allow user to select camera or gallery for image
