Android MapBox Java SDK error when displaying map

I'm trying to use the sdk in a java android project.
I use this sdk :
implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:6.3.0'
When i launch the screen with the Mapview, i got the "getDataNetworkTypeForSubscriber" error
When searching a solution to this error multiple answer tell to import this dependency
implementation 'com.mapbox.mapboxsdk:mapbox-android-telemetry:6.3.0'
But when i launch the screen with this dependecy i got this error :
java.lang.NoClassDefFoundError: Failed resolution of: Lcom/mapbox/android/telemetry/MapEventFactory;
....
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.mapbox.android.telemetry.MapEventFactory" on path: DexPathList[[zip file "/data/app/~~rUziWglMhPfBsvW8AaITbQ==/com.trema.encheres.dev-aI_CEkUkLFmlvawtp7adLQ==/base.apk"],nativeLibraryDirectories=[/data/app/~~rUziWglMhPfBsvW8AaITbQ==/com.trema.encheres.dev-aI_CEkUkLFmlvawtp7adLQ==/lib/arm64, /data/app/~~rUziWglMhPfBsvW8AaITbQ==/com.trema.encheres.dev-aI_CEkUkLFmlvawtp7adLQ==/base.apk!/lib/arm64-v8a, /system/lib64, /system_ext/lib64]]
What am I doing wrong ? Is there something i forgot ? A dependency ?
I try to add this dependency
implementation 'com.mapbox.mapboxsdk:mapbox-sdk-core:6.3.0'
but i got the error message when building :
Could not find com.mapbox.mapboxsdk:mapbox-sdk-core:6.3.0.
Thanks

Ionic/Cordova app does not find MainActivity

My app (Ionic 5 + Cordova 9.1.0) crashes when I try to start it on an Android 11 phone. When I look into the logs with logcat I see that the main activity is not found:
10-21 16:31:29.281 5300 5300 E AndroidRuntime:
java.lang.RuntimeException: Unable to instantiate activity
ComponentInfo{de.meingolfclub.myapp/de.meingolfclub.myapp.MainActivity}:
java.lang.ClassNotFoundException: Didn't find class

/system/lib64, /system_ext/lib64]]
I googled a bit and it seems to be related to multiDex functionality of Android, but I have no idea how to fix this in an Ionic/Cordova project.
What can I do to solve this problem?

I solved it.
There was a wrong package name in MainActivity. After removing the Android platform and adding it again the package name was correct. And after a build the starts again.

Android : Branch SDK Crash Issue in production build

I am using Branch SDK in my application (latest version of Android Branch SDK (v4.3.2))
Since last update I am facing class not found issue in production release. But in development it works without any issues. Here is the crash log from firebase.
Fatal Exception: java.lang.RuntimeException
Unable to instantiate receiver io.branch.referral.InstallListener: java.lang.ClassNotFoundException: Didn't find class "io.branch.referral.InstallListener" on path: DexPathList[[zip file "/system/framework/org.apache.http.legacy.boot.jar", zip file "/data/app/gman.vedicastro-dnsDZX6uCyAilVBlCp8zjQ==/base.apk"],nativeLibraryDirectories=[/data/app/gman.vedicastro-dnsDZX6uCyAilVBlCp8zjQ==/lib/arm64, /system/lib64]]
Caused by java.lang.ClassNotFoundException

As per the document from branch, I have removed this code from Android Manifest file
<receiver android:name="io.branch.referral.InstallListener" android:exported="true">
   <intent-filter>
   <action android:name="com.android.vending.INSTALL_REFERRER" />
   </intent-filter>
</receiver>
Any idea why this issue happened?
Please help me to resolve this. Thanks.

It could be a cache issue particularly when multidex builds are involved. I did following steps and it solves the problem - 
Disabling instant run on Android Studio.
Running the following command  ./gradlew clean && ./gradlew cleanbuildcache (note syntax is slightly different on Windows).
Finally relaunch Android Studio via File -> Invalidate caches / restart ...
Also, please double check the latest Android SDK (v4.3.2) documentation and confirm that you have added all the necessary command/code in all of the files. Here's the link to the latest doc - https://docs.branch.io/apps/android/
I hope this helps to someone.
Happy Coding :)

CoreComponentFactoryDidn't find class "android.support.v4.app.CoreComponentFactory"

I got sudden crash in my google pixel 2 having android 9 version.
Is there any hint what is the reason behind that and it is not reproducible every time.
detail logs...
Didn't find class "android.support.v4.app.CoreComponentFactory" on
path: DexPathList[[zip file
"/data/app/com.google.android.deskclock-o_Iury9TRKVebStZjRrd0g==/base.apk"],nativeLibraryDirectories=[/data/app/com.google.android.deskclock-o_Iury9TRKVebStZjRrd0g==/lib/arm64,
/system/lib64]]

Just clean the build and run it will go away

android ClassNotFoundException after trying to change minimum sdk

I am really getting desperate.
I have a working app - theoretically.
Tried to change the sdk version from 8 to 13.
Now when I start the app I get a Fatal exception, or rather a ClassNotFoundException for the very first activity started:
10-15 16:56:22.370: E/AndroidRuntime(862): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.example.pris/com.example.pris.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "com.example.pris.MainActivity" on path: DexPathList[[zip file "/data/app/com.example.pris-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.example.pris-1, /system/lib]]
Apparently there seems to be some mixup with paths, but I have not the slightes idea where, or how to fix this.
Please help!
