I did not checked the sample code or the java source as yet.
It crashes in this line as the event.getPackageName() and event.getClassName() are null

            ComponentName componentName = new ComponentName(event.getPackageName().toString(), event.getClassName().toString());

Unsure why this is happening to you...I have tested it on numerous devices and never seen the first crash-problem after approving the app.service, nor the error shown in your Stacktrace. Try to uninstall the app and then run it again.
Which device do you have?

Try to uninstall the app and then run it again.

That did the trick

Which device do you have?

Samsung Note 8, 'Android 8.0

I am getting the same error. I tried uninstalling and reinstalling. What happens is when you reinstall the app, our Whatsapp Accessibility service is again disabled by default. In that state if you type a message and hit the send button, it opens Whatsapp, finds the corresponding chat for the contact, types in the message but does not hit the Send button by itself as the Accessibility service is not enabled.

As soon as you enable this service, it crashes again. Tried reinstalling multiple times.

My Devices

• Samsung Galaxy S8+ (Android 8.0)
• Huawei P20 Pro (Android 8.1)

Is there any other accessibility service running on the phone?

 

[Inman]

You are right. There was an accessibility service for an app called Universal Copy that I use to copy text from apps that do not allow copying. When I disable that app's accessibility service, your example works great.

So does that mean only one accessibility service can be used at any time? Doesn't seem to affect Universal Copy as it continues to work even when the service in this example is turned on.

 

[moster67]

Not sure about that. I think I read this might be the case but the documentation is not very clear. Maybe someone could google it or ask on Stackoverflow ..

 

[moster67]

Doesn't seem to affect Universal Copy as it continues to work even when the service in this example is turned on.

Maybe a configuration issue? I will have a look in a few weeks when I get back

Thanks man. I will wait.
