I got the following log error in my route tracking activity
06-24 18:50:24.488 7128-7759/com.noureddine_ouertani.www.wocelli50 E/DynamiteModule: Failed to load module descriptor class: Didn't find class "com.google.android.gms.dynamite.descriptors.com.google.android.gms.googlecertificates.ModuleDescriptor" on path: DexPathList[[zip file "/data/app/com.noureddine_ouertani.www.wocelli50-2/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]
After reading some posts and answers about this log error I figured out that it's a known Google Play Services version 9.0.83 issue that causes bugs in some apps that use a GoogleApiClient like mine.
However I didn't test the solution yet. I wanted to downgrade Google Play Services on my Smartphone but Uninstall Updates was greyed out (see Screenshot).
Does anyone know how to do this manually?
I installed the Android Device Manager app but found no possibility to influence the stop/uninstall updates buttons of Google Play Services. Then I tried to apply this solution but the System App Remover app got no root permission on my Smartphone.
Any hints or help?
