Java – audiorecord object is not initialized in the project
•
Java
When I try to record audio with my nexus 5 using the following code
record = new AudioRecord(MediaRecorder.AudioSource.MIC,sampleRate,AudioFormat.CHANNEL_IN_MONO,AudioFormat.ENCODING_PCM_8BIT,BYTE_OF_SAMPLE * bufferSampleSize); record.startRecording();
Then I get the following exception in logcat:
E/AudioRecord: AudioFlinger Could not create record track,status: -1 E/AudioRecord-JNI: Error creating AudioRecord instance: initialization check Failed with status -1. E/android.media.AudioRecord: Error code -20 when initializing native AudioRecord object. E/AndroidRuntime: FATAL EXCEPTION: Thread-855 E/AndroidRuntime: Process: com.*.*,PID: 14206 E/AndroidRuntime: java.lang.IllegalStateException: startRecording() called on an uninitialized AudioRecord. E/AndroidRuntime: at android.media.AudioRecord.startRecording(AudioRecord.java:885) E/AndroidRuntime: at com.*.*.MainActivity$Looper.run(MainActivity.java:265) E/Surface: getSlotFromBufferLocked: unkNown buffer: 0x9e476d00
I added the following line to the manifest file
<uses-permission android:name="android.permission.RECORD_AUdio" />
I have tested audiorecord object not initializing None of these solutions exist
But it works on another project What's missing?
