Texttospeech.setenginebypackagename() Doesn't Set Anything

Following the tip in this answer, I placed a call to setEngineByPackageName right in onActivityResult(), when requestCode == REQ_TTS_STATUS_CHECK && TextToSpeech.Engine.CHE

Solution 1:

You say that you placed the call to setEngineByPackageName in onActivityResult(). This is the wrong place to do this.

setEngineByPackageName, just like getDefaultEngine, must not be called before reaching onInit().
