Service not registered: android.speech.tts.TextToSpeech

Question

I am testing my application for accessibility. If user switch off accessibility in mid between then application crashes with the reason Service not registered: android.speech.tts.TextToSpeech. I have called setJavaScriptEnabled(false) in onDetachedFromWindow method but there was no use. Still error is coming.

I haven't use application context in webview because webview is getting initialized using xml.

Answer 1

Finally it has solved. I have to move all webview from the xml file and have added them dynamically and passing application context.

WebView webView = new WebView(getApplicationContext());
