Crash randomly after rendering TexView

[willemstuijt]

More or less 1 out of the 8 times I render LaTeX with TeXView my app crashes when running on a Moto One (Android). It is very random.

Sometimes I get this error, this one usually happens when I have a TeXView in one route and I push another route with a TeXView: E/AndroidRuntime(13787): FATAL EXCEPTION: main E/AndroidRuntime(13787): Process: com.app.my_app, PID: 13787 E/AndroidRuntime(13787): java.lang.NullPointerException: Attempt to read from field 'android.view.WindowManager$LayoutParams android.view.ViewRootImpl.mWindowAttributes' on a null object reference E/AndroidRuntime(13787): at android.view.inputmethod.InputMethodManager.startInputInner(InputMethodManager.java:1625) E/AndroidRuntime(13787): at android.view.inputmethod.InputMethodManager.checkFocus(InputMethodManager.java:1864) E/AndroidRuntime(13787): at android.view.inputmethod.InputMethodManager.isActive(InputMethodManager.java:1183) E/AndroidRuntime(13787): at io.flutter.plugins.d.l2$a.run(Unknown Source:42) E/AndroidRuntime(13787): at android.os.Handler.handleCallback(Handler.java:883) E/AndroidRuntime(13787): at android.os.Handler.dispatchMessage(Handler.java:100) E/AndroidRuntime(13787): at android.os.Looper.loop(Looper.java:241) E/AndroidRuntime(13787): at android.app.ActivityThread.main(ActivityThread.java:7617) E/AndroidRuntime(13787): at java.lang.reflect.Method.invoke(Native Method) E/AndroidRuntime(13787): at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:492) E/AndroidRuntime(13787): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:941)

And sometimes I get this other error: PlatformException (PlatformException(error, Permission Denial: get/set setting for user asks to run as user -2 but is calling from uid u0a279; this requires android.permission.INTERACT_ACROSS_USERS_FULL, null, java.lang.SecurityException: Permission Denial: get/set setting for user asks to run as user -2 but is calling from uid u0a279; this requires android.permission.INTERACT_ACROSS_USERS_FULL at android.os.Parcel.createException(Parcel.java:2071) at android.os.Parcel.readException(Parcel.java:2039) at android.os.Parcel.readException(Parcel.java:1987) at android.view.IWindowSession$Stub$Proxy.addToDisplay(IWindowSession.java:1242) at android.view.ViewRootImpl.setView(ViewRootImpl.java:889) at android.view.WindowManagerGlobal.addView(WindowManagerGlobal.java:387) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:95) at android.app.Dialog.show(Dialog.java:342) at android.app.Presentation.show(Presentation.java:257) at io.flutter.plugin.platform.VirtualDisplayController.(VirtualDisplayController.java:95) at io.flutter.plugin.platform.VirtualDisplayController.create(VirtualDisplayController.java:48) at io.flutter.plugin.platform.PlatformViewsController$1.createVirtualDisplayForPlatformView(PlatformViewsController.java:212) at io.flutter.embedding.engine.systemchannels.PlatformViewsChannel$1.create(PlatformViewsChannel.java:107) at io.flutter.embedding.engine.systemchannels.PlatformViewsChannel$1.onMethodCall(PlatformViewsChannel.java:59) at io.flutter.plugin.common.MethodChannel$IncomingMethodCallHandler.onMessage(MethodChannel.java:233) at io.flutter.embedding.engine.dart.DartMessenger.handleMessageFromDart(DartMessenger.java:84) at io.flutter.embedding.engine.FlutterJNI.handlePlatformMessage(FlutterJNI.java:865) at android.os.MessageQueue.nativePollOnce(Native Method) at android.os.MessageQueue.next(MessageQueue.java:343) at android.os.Looper.loop(Looper.java:188) at android.app.ActivityThread.main(ActivityThread.java:7617) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:492) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:941) Caused by: android.os.RemoteException: Remote stack trace: at com.android.server.am.UserController.handleIncomingUser(UserController.java:1660) at com.android.server.am.ActivityManagerService.handleIncomingUser(ActivityManagerService.java:14500) at android.app.ActivityManager.handleIncomingUser(ActivityManager.java:3813) at com.motorola.android.providers.settings.MotorolaSettingsProvider.resolveCallingUserIdEnforcingPermissionsLocked(MotorolaSettingsProvider.java:1154) at com.motorola.android.providers.settings.MotorolaSettingsProvider.getSecureSetting(MotorolaSettingsProvider.java:791)
