Reproduce the Speed Test app crash with microG 0.2.4-108 on Android 7.1.2 and compare it with 0.2.4-107. Start with the reported ContextImpl.getSharedPreferences failure and the com.google.android.gms ads initialization frames. Done means the app no longer crashes during ad loading; no source file or test is named in the issue.
