ImageView not retaining Image when android device restart

I have images selected from the gallery displayed in ImageView, But not retaining or saved Image when the android device restart I need to re-pick an image again. My plan is for the image to still stay on the image view even the device is rebooted , or do I need to create some data to save the image and display to ImageView

public class FirstFragment extends Fragment implements View.OnClickListener{
ImageView imageButton1;
private Uri mImageUri;
@Override
public void onResume() {
super.onResume();
}
private File mSnapFile;
private static final String ARG_URI_IMAGE_1 = "image1Uri";
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v= inflater.inflate(R.layout.fragment_first, container, false);
imageButton1 = (ImageView) v.findViewById(R.id.firstimagebtn);
imageButton1.setOnClickListener(this::onClick);
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
String mImageUri = preferences.getString("image", null);
if (mImageUri != null) {
imageButton1.setImageURI(Uri.parse(mImageUri));
} 
return v;
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.firstimagebtn:
Intent intent;
if (Build.VERSION.SDK_INT < 19) {
intent = new Intent(Intent.ACTION_GET_CONTENT);
} else {
intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
}
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), 0);
break;
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode) {
case 0:
if(resultCode == Activity.RESULT_OK){
if (data != null) {
// This is the key line item, URI specifies the name of the data
mImageUri = data.getData();
// Saves image URI as string to Default Shared Preferences
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
SharedPreferences.Editor editor = preferences.edit();
editor.putString("image", String.valueOf(mImageUri));
editor.commit();
// Sets the ImageView with the Image URI
imageButton1.setImageURI(mImageUri);
imageButton1.invalidate();
}
}
break;
case 1:
if(resultCode == Activity.RESULT_OK){
// This is the key line item, URI specifies the name of the data
mImageUri2 = data.getData();
// Saves image URI as string to Default Shared Preferences
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
SharedPreferences.Editor editor = preferences.edit();
editor.putString("image2", String.valueOf(mImageUri2));
editor.commit();
// Sets the ImageView with the Image URI
imageButton2.setImageURI(mImageUri2);
imageButton2.invalidate();
}
break;
}
}

You can use image loading libraries like Glide or Picasso. They provide data caching and your image will be persisted.

See docs

By default, Glide checks multiple layers of caches before starting a new request for an image:

1.Active resources - Is this image displayed in another View right now?

2.Memory cache - Was this image recently loaded and still in memory?

3.Resource - Has this image been decoded, transformed, and written to the disk cache before?

4.Data - Was the data this image was obtained from written to the disk cache before?

The first two steps check to see if the resource is in memory and if so, return the image immediately. The second two steps check to see if the image is on disk and return quickly, but asynchronously.

If all four steps fail to find the image, then Glide will go back to the original source to retrieve the data (the original File, Uri, Url etc).

Hope this helps. Let me know if you face an issue with this but I think the docs are pretty much self explanatory.
