NullPointerException when invoke AppInstallHelper.InstallationHelper.InstallApp

[UlyssesWu]

I have tried on different devices, and they all throw this:

Java.Lang.NullPointerException: 'Attempt to invoke virtual method 'boolean android.content.Intent.migrateExtraStreamToClipData(android.content.Context)' on a null object reference'

when invoke this line:

await Plugin.XF.AppInstallHelper.InstallationHelper.InstallApp(apkPath, Plugin.XF.AppInstallHelper.InstallMode.OutOfAppStore);

any ideas?
