I am working on an Android application named cricket-info. Used Firestore database. When I run this application on an Android emulator (virtual device) it shows this warning and my data is not updated on firebase even taking more time to authenticate the user to the app. But whenever I run this app on a physical device my data gets updated and takes very less time to authenticate user...!
Code:
final _firestore = FirebaseFirestore.instance;
Also tried reinstalling Android Studio and Flutter.

Google Maps API SDK Crash

I have an navigation app that uses offline tiles along with google maps api v2.
The first time I open the app, the api connects to google server so it can download google play certificate ( I think) and then it works with the oflline tiles that are stored in the device. After the first connection, the application can stay offline and continue to work fine.
In my last build, after 3-4 days of using the app, the offline (tiles,markers,polygons,etc) capability is lost and the api needs to connect again to the internet as to continue function.
When I go online then the application starts to work again.
What I have done until now:
Checked that the google maps api key is correct (it works fine when I connect to the internet)
Add the application SHA to the google api console
Try restricted/unrestricted of the api key
I attach three logcat when opening the app
1)Opening the app offline and the google api doesnt work:

One difference I can spot is on line #6 V/DynamiteModule: Dynamite loader version >= 2, using loadModule2NoCrashUtils when the google maps api stops to work.
Maybe its something with my dependecies?

Google Mobile Vision ocrlib.so file downloading error

This vision message is what causing the problem:
**E/Vision:Request download for engine ocr is a no-op because rate limiting**

Finally i was able to resolve this issue by factory resetting the device. I was using the knox profile so first i unassigned the existing knox profile and then factory reset the device and it was workign fine. Cheers!

Unable to decode stream: android.graphics.ImageDecoder$DecodeException: Failed to create image decoder with message 'unimplemented'

I've recently tried implementing Pusher's Chatkit into my android app along with some Kotlin plugins and am now running into this error that I cannot resolve.
E/Drawable: Unable to decode stream: android.graphics.ImageDecoder$DecodeException: Failed to create image decoder with message 'unimplemented'Input contained an error.
the error I'm getting right below it is:
E/FirebaseInstanceId: Token retrieval failed: SERVICE_NOT_AVAILABLE
Which is through throwing me for a loop because my internet is working fine although a couple lines further down, I get:
W/Firestore: (21.3.0) [OnlineStateTracker]: Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds.
This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.
Process 15216 terminated.
Note: I've started to get this error above about not having a good connection ever since I started working more at cafes instead of at home since I needed to get out. In order to work offline, firebase asked me to opt into an offline mode I've been getting this notification of not being able to connect ever since.
I am following along to the getting started page here and have completed up to the end of the "Displaying Messages" section however when I go to the activity, it just stalls and blanks out. I have been searching StackO and the rest of the web for the past 2 days to try to resolve the conflict to no avail. All of the similar posts I have looked at dont seem to resolve the issue.
similarPost#1 but I'm not trying to save to a bitmap
Here is the entire stack trace:

It seems to have fixed itself except for the unable to decode stream error however it doesn't crash, it just shows up in the log.
I checked for updates, cleaned, rebuild, invalidated caches and restarted, and shut down my emulator. I also restarted my computer completely 2x and that seems to have fixed it.

Android Google Map sometimes not working

I have two Activities both using com.google.android.gms.maps.MapView. The API key is properly set up. One Activity is working fine, the other is showing grey screen and
... W/DynamiteModule: Local module descriptor class for com.google.android.gms.googlecertificates not found.
... I/DynamiteModule: Considering local module com.google.android.gms.googlecertificates:0 and remote module com.google.android.gms.googlecertificates:3
... I/DynamiteModule: Selected remote version of com.google.android.gms.googlecertificates, version >= 3
... W/System: ClassLoader referenced unknown path: /data/user_de/0/com.google.android.gms/app_chimera/m/00000000/n/x86
Anyone knows what may be going wrong?

Found the reason. This happens if you write to fast and forget to forward life cycle events from onCreate, onResume, onPause, onLowMemory, onSaveInstanceState, onDestroy to the map.
