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?

  • Then I tried to apply this solution but the System App Remover app got no root permission on my Smartphone, like i said in my answer at that chatroom, Did you check if your device is root or not? with an app such as; play.google.com/store/apps/details?id=com.joeykrim.rootcheck ? – ʍѳђઽ૯ท Jun 25 '16 at 10:34

    Apart from that: "this issue", "this solution" – references are a good thing. But don't expect people following a couple of links to understand your problem (most won't), better include the essentials so readers have a chance to get an idea without having to follow the link (but can do so for additional details). – Izzy Jun 25 '16 at 11:27
  • +1 for the Izzy comment. I did not track the links to understand your problem or incorporate what you believed was a remediation of it. Please edit all information into your posting. – wbogacz Jun 25 '16 at 11:40
  • Post edited. thanks for your comments. PS: I''m rooting my device right now and will post here whether I solved the problem. – Noureddine Ouertani Jun 25 '16 at 11:46

I solved the problem for my Huawei P8 Lite Android phone like this:

  1. I unlocked my bootloader
  2. I rooted my phone
  3. I succesfully checked with Root Checker Basic that my phone is rooted
  4. I downloaded and installed System App Remover from the Google Play Store.
  5. I put my device in Airplane Mode in order to prevent auto upgrade of GPS.
  6. I opened System App Remover and select "System App" from the menu.
  7. After I found Google Play Services in the list which was marked as "Should keep" I selected it and pressed "Uninstall". I ignored the next warning.
  8. Using Settings/Apps, I saw that Google Play Services "Uninstall Updates", and "Disable" Buttons were no longer be grayed out.
  9. I pressed "Uninstall Updates"

Here is the result: Downgrade of Google Play Services to 8.1.18

    This reprieve may be temporary. I don't believe you can prevent the automatic upgrade, either intentionally or as its byproduct of other Google app(s) updates. You'll probably encounter this again, unless it is/was isolated to the specific version you had encountered the problem. With luck later versions will eradicate the bug, and the problems it caused. – wbogacz Jun 28 '16 at 1:41
