Question

我想使用android marshmallow录制通话，因为我使用了以下代码

 myAudioRecorder = new MediaRecorder();
                //myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
                myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
                myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
                myAudioRecorder.setOutputFile(outputFile);
                myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);

但是我的logcat

了

    Request requires android.permission.CAPTURE_AUDIO_OUTPUT
 E/AudioPolicyIntefaceImpl: getInputForAttr() permission denied: capture not allowed

Answer 1

第三方应用不允许此权限。检查此链接。 https://developer.android.com/reference/android/Manifest.permission.html#CAPTURE_AUDIO_OUTPUT

Answer 2

您需要在运行时请求权限

 ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.CAPTURE_AUDIO_OUTPUT},
                    1);

稍后在

进行处理

@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
 switch (requestCode) {
    case 1: {
     for(int i:grantResults){
       if(i == PackageManager.PERMISSION_GRANTED){
         // do your stuff here.
        }
     }
 }
}
