Description
On some devices, we get a NullPointer exception when loading the app from install.
The workaround is for the user to clear the app cache to make the app work. However, this is not possible for end-users.
Errors
java.lang.NullPointerException: Attempt to invoke interface method ‘java.lang.String android.content.SharedPreferences.getString(java.lang.String, java.lang.String)’ on a null object reference at com.zipow.videobox.util.PreferenceUtil.readStringValue(PreferenceUtil.java:5) at org.webrtc.voiceengine.VoiceEngineCompat.selectAudioDeviceAPIType(VoiceEngineCompat.java:1) at org.webrtc.voiceengine.VoiceEngineCompat.isBluetoothScoCupported(VoiceEngineCompat.java:33) at us.zoom.internal.SDKApplication.onSDKCreated(SDKApplication.java:50) at us.zoom.internal.SDKApplication.initializeForSDK(SDKApplication.java:8) at us.zoom.sdk.d.initialize(ZoomVideoSDKImpl.java:18) at com.reactnativezoom.videosdk.RNZoomVideoSdkModule$1.run(RNZoomVideoSdkModule.java:120) at android.os.Handler.handleCallback(Handler.java:914)
