Title Body

My problem is simple to explain -- I am trying to create a AudioRecord object but it fails to initialize (ie after the constructor, getState returns 0, indicating failure). I am running this from Eclipse on a MotoDroid 1 running OS 2.2.1. My AndroidManifest.xml is, AFAIK, using the right permission, RECORD_AUDIO (I don't know how to confirm this): <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> <uses-permission android:name="android.permission.RECORD_AUDIO"/> <activity android:name=".SphinxMic" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> I do the following to create the AudioRecord: bufferSize = AudioRecord.getMinBufferSize(8000, CHANNEL_IN_MONO, ENCODING_PCM_8BIT); audioRecorder = new AudioRecord(AudioSource.MIC, 8000, CHANNEL_IN_MONO, ENCODING_PCM_8BIT, 50*bufferSize); if (audioRecorder.getState() != AudioRecord.STATE_INITIALIZED) throw new Exception("AudioRecord init failed"); audioRecorder.getState() returns 0 (ie STATE_UNINITIALIZED) I have not found any complete examples of using this API and I'm very much an Android beginner so the solution may well be something simple. What can I do to find out why it fails? A few people have asked similar questions, but they must have been having different problems than me because the fixes they approve haven't helped me. Most notably this . But the approved solution is perplexing and didn't work for me anyway. I have also tried a variety of bit rates (8000, 16000, 11025, 44100), both mono and stereo an
