阅读更多关于 SpeechRecognizer causes ANR… I need help with Android speech API

问题 EDIT : I should have mentioned this already, but I\'m running this code in a service. The entire app is turned on/off by a widget button and has no activity. Update : I tried attaching the SDK sources to the project so I could get a more precise idea of where the failure was occurring, but from the looks of it, only public APIs are included, which seems to make them a lot less useful... can anyone suggest at least a debugging approach for solving this issue?
