My app is crashing after I implement In-App-Update from Play Store

My app is building successfully but when I open it it closes by itself...
I was able to successfully implement In-App-Review! But Update is failing and crashing my app on start.
I have an error in AppUpdateManager. I reproduced the code from scratch line by line... And the app crashed on its own, after build, when I called the App Update Manager:
private final AppUpdateManager mAppUpdateManager = AppUpdateManagerFactory.create(this);

Only Can be instancied on one time.

Can you use Flutter MethodChannel to return a native map from Java

I am attempting to to create a widget from a native view navigation map using method channels and AndroidViews but I keep running into this problem:
E/MethodChannel#flutter/platform_views( 2258): Failed to handle method call
E/MethodChannel#flutter/platform_views( 2258): java.lang.IllegalArgumentException: Cannot add a null child view to a ViewGroup.
Here is the flutter Code :
Main.dart
import 'navigation_view.dart';
import 'package:expandable_bottom_sheet/expandable_bottom_sheet.dart';
import 'package:flutter/material.dart';
import 'customButton1.dart';
import 'Constantes.dart';
void main() => runApp(MaterialApp(home: TextViewExample()));
class TextViewExample extends StatefulWidget {
#override
_TextViewExampleState createState() => _TextViewExampleState();
}
class _TextViewExampleState extends State<TextViewExample>
with SingleTickerProviderStateMixin {
#override
void initState() {
super.initState();
}
Widget build(BuildContext context) {
// var s = NavigationView(
// onNavigationViewCreated: _onNavigationViewCreated,
// );
double screenWidth, screenHeight;
Size size = MediaQuery.of(context).size;
screenHeight = size.height;
screenWidth = size.width;
print("FLUTTER INIT");
return Scaffold(
body: SafeArea(
child: Stack(children: [
Positioned(
width: screenWidth,
height: screenHeight - 220,
child: Container(
child: NavigationView(
onNavigationViewCreated: _onNavigationViewCreated,
),
),
),
Positioned(
bottom: 75,
child: Container(
height: screenHeight,
width: screenWidth,
void _onNavigationViewCreated(NavigationViewController controller) {}
}
Here is navigation_view.dart
import 'dart:async';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
typedef void NavigationViewCreatedCallback(NavigationViewController controller);
class NavigationView extends StatefulWidget {
const NavigationView({
Key key,
this.onNavigationViewCreated,
}) : super(key: key);
final NavigationViewCreatedCallback onNavigationViewCreated;
#override
State<StatefulWidget> createState() => _NavigationViewState();
}
class _NavigationViewState extends State<NavigationView> {
#override
Widget build(BuildContext context) {
if (defaultTargetPlatform == TargetPlatform.android) {
return AndroidView(
viewType: 'com.Mavic.Cabinn/navigationview',
onPlatformViewCreated: _onPlatformViewCreated,
);
}
return Text(
'$defaultTargetPlatform is not yet supported by the navigation_view plugin');
}
void _onPlatformViewCreated(int id) {
if (widget.onNavigationViewCreated == null) {
return;
}
widget.onNavigationViewCreated(new NavigationViewController._(id));
}
}
class NavigationViewController {
NavigationViewController._(int id)
: _channel = new MethodChannel(
'com.Mavic.Cabinn/navigationview$id');
final MethodChannel _channel;
// Future<void> setNavigation() async {
// try {
// Future.delayed(const Duration(seconds: 1), () async {
// await _channel.invokeMethod('EmpezarNavegacion');
//
// return;
// });
// } on PlatformException catch (e) {
// print(e);
// }
// Future<void> setNavigation() async {
// assert(AndroidView != null);
// return _channel.invokeMethod('EmpezarNavegacion');
// }
//}
Future<dynamic> setNavigation() async {
String message;
try {
final String result = await _channel.invokeMethod('EmpezarNagevacion');
message = result;
} on PlatformException catch (e) {
print(message);
}
}
}

I used this article as reference in order to attempt to replicate this but I hit many a speed bump trying to get this to work properly: https://medium.com/flutter-community/flutter-platformview-how-to-create-flutter-widgets-from-native-views-366e378115b6

Like I was saying ive been attempting to find a null value and searched high and low for questions similar to this one but Ive had no such luck as this is not something Ive seen done. I also checked if there were any plugins to create and embedded map and unfortunately there arent any at the moment.

How to show images with indirect link/URL using Glide

I am trying to download blog features images form a WordPress blog page and then load them later.
Right now, every time the user scrolls down and up the image load again and again. Any idea...plzzz..I tried many solutions, for example, this one:
Preload multiple images with Glide
But, it didn't work.
I am using implementation 'com.github.bumptech.glide:glide:3.7.0'
And this is my code:
RecyclerViewAdapter
public void getthumbnail(String imageurl, final ImageView imageView, final int position){
ServiceWrapper serviceWrapper = new ServiceWrapper(null);
Call<GetThumbnail> call = serviceWrapper.getThumbnailCall(imageurl);
call.enqueue(new Callback<GetThumbnail>() {
#Override
public void onResponse(Call<GetThumbnail> call, Response<GetThumbnail> response) {
if (response.body() != null && response.isSuccessful()) {
try {
if (response.body().getMediaDetails()!=null){
// Log.e("recycler adapter", " image is here-- " + response.body().getMediaDetails().getSizes().getThumbnail().getSourceUrl());
// Log.e("Full IMG SIZE - ", " THIS IS FULL IMAGE URL-- " + response.body().getMediaDetails().getSizes().getFull().getSourceUrl());
imagepath.add(position, response.body().getMediaDetails().getSizes().getFull().getSourceUrl());
Glide.with(mContext)
.load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.into(imageView);
}else {
}
}catch (Exception e){
// Log.e("adapter", "fail not media tag "+ e.toString());
}
}
}
#Override
public void onFailure(Call<GetThumbnail> call, Throwable t) {
// Log.e("adapter", " faile image "+t.toString());
}
});
}
UPDATE
I found this code and I put it on top of the other Glide code but it didn't work:
Glide.with(mContext)
.load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
.downloadOnly(new SimpleTarget<File>() {
#Override
public void onResourceReady(File resource, GlideAnimation<? super File> glideAnimation) {
}
});
UPDATE:
Now I used this code and it doesnt download the images faster:
Glide.with(mContext)
.load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
.downloadOnly(new SimpleTarget<File>() {
#Override
public void onResourceReady(File resource, GlideAnimation<? super File> glideAnimation) {
Glide.with(mContext)
.load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.into(imageView);
}
});

UPDATE
So, now that I tried to update glide 3 to 4.x I am getting the following in error in build.gradle.
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 27.1.1, 27.1.0, 26.1.0. Examples include com.android.support:support-compat:27.1.1 and com.android.support:animated-vector-drawable:27.1.0 less... (⌘F1)
There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion).

The loading delay problem and image item disposition comes from onBindViewHolder method where you call a webservice in it. Everytime a list item is appeared in scrolling, onBindViewHolder is called to initialize the view with correct values. So you should not call a webservice here at all (but in the code it is called everytime). As Glide creates a queue of requests, it guarantees that the image would be downloaded only one time because it caches them. Also it guarantees that the image would be loaded if the ImageView is in visible area of the RecyclerView in scrolling process.
On the other hand, reaching the image url in your case needs two level of webservice api-s. So we should combine Glide procedure and retrieving the image url procedure to reach the best performance. Using Glide-OkHttp3-Integration library, I have developed this two level of asynchronous calls which makes the Glide aware of your data flow.
• Note that you should clean and rebuild your project to create GlideApp class in compile time.

• First of all, I strongly recommend you to use Glide v4.
The loading delay problem and image item disposition comes from onBindViewHolder method where you call a webservice in it. Everytime a list item is appeared in scrolling, onBindViewHolder is called to initialize the view with correct values. So you should not call a webservice here at all (but in the code it is called everytime). As Glide creates a queue of requests, it guarantees that the image would be downloaded only one time because it caches them. Also it guarantees that the image would be loaded if the ImageView is in visible area of the RecyclerView in scrolling process. In addition, by setting diskCacheStrategy to DiskCacheStrategy.ALL, Glide shows an image which is resized according to the ImageView size.
#Override
public void onBindViewHolder(final RecyclerView.ViewHolder holder, final int position) {
final Model object = dataset.get(position);
if (Build.VERSION.SDK_INT >= 24) {
// ( (ImageTypeViewHolder) holder).subtitle.setText(Html.fromHtml(object.subtitle , Html.FROM_HTML_MODE_LEGACY));
((ImageTypeViewHolder) holder).title.setText(Html.fromHtml(object.title , Html.FROM_HTML_MODE_LEGACY));
((ImageTypeViewHolder) holder).date.setText(Html.fromHtml(object.date , Html.FROM_HTML_MODE_LEGACY));
} else {
// ((ImageTypeViewHolder) holder).subtitle.setText(Html.fromHtml(object.subtitle));
((ImageTypeViewHolder) holder).title.setText( Html.fromHtml(object.title));
((ImageTypeViewHolder) holder).date.setText( Html.fromHtml(object.date));
}
((ImageTypeViewHolder) holder).imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(mContext, WPPostDetails.class);
intent.putExtra("itemPosition", position);
mContext.startActivity(intent);
}
});
Glide.with(imageView.getContext())
.load(object.Image)
.apply(RequestOptions.diskCacheStrategyOf(DiskCacheStrategy.ALL))
.into(imageView);
}
By the above changes, your RecyclerView should work smoothly as well as fast. If you want to make Glide more integrated with RecyclerView, you can follow this. But I think this is not necessary and the previous level is enough.

The current version for Glide is '4.8.0'. Any reason you don't want to work with that version? https://github.com/bumptech/glide
https://github.com/bumptech/glide/blob/master/samples/flickr/src/main/java/com/bumptech/glide/samples/flickr/FlickrPhotoGrid.java
You need to use a RecyclerView. Here is an example:
grid.addItemDecoration(new RecyclerView.ItemDecoration() {
#Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent,
RecyclerView.State state) {
outRect.set(gridMargin, gridMargin, gridMargin, gridMargin);
}
});
grid.setRecyclerListener(new RecyclerView.RecyclerListener() {
#Override
public void onViewRecycled(RecyclerView.ViewHolder holder) {
PhotoViewHolder photoViewHolder = (PhotoViewHolder) holder;
GlideApp.with(FlickrPhotoGrid.this).clear(photoViewHolder.imageView);
}
});

I did not solve this problem in 3 days. I really need help

OK: "setFactory2()" is NOT static; it should be a member of an LayoutInflator class instance. For example:
https://www.programcreek.com/java-api-examples/?class=android.view.LayoutInflater&method=setFactory2
static void setFactory(LayoutInflater inflater, LayoutInflaterFactory factory) {
Factory2 factory2 = factory != null ? new FactoryWrapperHC(factory) : null;
inflater.setFactory2(factory2);
Factory f = inflater.getFactory();
if (f instanceof Factory2) {
forceSetFactory2(inflater, (Factory2) f);
} else {
forceSetFactory2(inflater, factory2);
}
}
SUGGESTIONS:
Q: Do you have (an XML) layout? Is it (are they) configured correctly?
Q: Does your Android app work standalone (independent of espresso)?
