Android camera capture activity returns null Uri

Question

This code worked on samsung before but now that i'm using Nexus One with Android 2.3.6, it's crashing as soon as I take a picture and click ok or choose a photo from gallery. Stacktrace shows a null pointer exception on the Uri. My code for the activating the camera is as follows: ``` public void activateCamera(View view){ Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); // start the image capture Intent startActivityForResult(i, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if ((requestCode == CHOOSE_IMAGE_ACTIVITY_REQUEST_CODE || requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) && resultCode == RESULT_OK && null != data) { selectedImage = data.getData(); String[] filePathColumn = { MediaStore.Images.Media.DATA }; Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null); cursor.moveToFirst(); int columnIndex = cu…

Accepted Answer

You have to tell the camera, where to save the picture and remeber the uri yourself:

```
private Uri mMakePhotoUri;

private File createImageFile() {
    // return a File object for your image.
}

private void makePhoto() {
    try {
        File f = createImageFile();
        Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        mMakePhotoUri = Uri.fromFile(f);
        i.putExtra(MediaStore.EXTRA_OUTPUT, mMakePhotoUri);
        startActivityForResult(i, REQUEST_MAKE_PHOTO);
    } catch (IOException e) {
        Log.e(TAG, "IO error", e);
        Toast.makeText(getActivity(), R.string.error_writing_image, Toast.LENGTH_LONG).show();
    }
}

@Override
public void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
    switch (requestCode) {
        case REQUEST_MAKE_PHOTO:
            if (resultCode == Activity.RESULT_OK) {
                // do something with mMakePhotoUri
            }
            return;
        default: // do nothing
            super.onActivityResult(requestCode, resultCode, data);
    }
}
```

You should save the value of `mMakePhotoUri` over instance states withing `onCreate()` and `onSaveInstanceState()`.
