Android Question Google Pre-launch Report

Paul Leischow · May 27, 2019

I have uploaded a APK created with B4A to the Google Play Console.
After a short time I receive a pre-launch report with 9 warning identified stating my app is using grey listed API's and Google can't guarantee they will work on existing devices.

As far as I can tell I am using the libraries that come with B4A...

Animation / Audio / ByteConverter / Core / Encryption / GoogleMaps / GPS / InAppBilling3 / JavaObject / JSON / OkHttpUtils2 / Phone / Phone / Reflection / RunTimePermissions / SQL / TTS

The Google warnings start like this and there are 9 in total...

StrictMode policy violation: android.os.strictmode.NonSdkApiUsedViolation: Lcom/android/org/conscrypt/OpenSSLSocketImp

StrictMode policy violation: android.os.strictmode.NonSdkApiUsedViolation: Lcom/android/org/conscrypt/OpenSSLSocketImp

StrictMode policy violation: android.os.strictmode.NonSdkApiUsedViolation: Landroid/os/Message;->flags:I

StrictMode policy violation: android.os.strictmode.NonSdkApiUsedViolation: Landroid/os/Message;->recycleUnchecked()V

etc...

Has anyone else experienced this? Should I be concerned as I do not know what these are?

Paul Leischow · May 27, 2019

After some more searching I came across someone else with report warnings and it seems to be common.

Is there a reason why Google does not like these and gives an error?
Is it a problem with the code created using B4A ?

Erel · May 28, 2019

You can ignore these two:
StrictMode policy violation: android.os.strictmode.NonSdkApiUsedViolation: Landroid/os/Message;->flags:I

StrictMode policy violation: android.os.strictmode.NonSdkApiUsedViolation: Landroid/os/Message;->recycleUnchecked()V

Don't call DoEvents or Msgbox and these flags will never be accessed.

I'm not sure where the other two come from. If there is more information post it.

Here is a couple of stack traces from one of the warnings...

They are related to reflection calls inside OkHttp (https://github.com/status-im/status-react/issues/8177). You can ignore them. OkHttp works properly on all devices.
I guess that at some point a new version of OkHttp will be released that will not include these calls.
