android mediaRecorder.setAudioSource失败
我有Android G1固件1.6，我试图用以下代码记录应用程序的声音。
MediaRecorder recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setOutputFile(PATH_NAME); recorder.prepare(); recorder.start();
我的manifest.xml有：
<uses-permission android:name="android.permission.RECORD_AUDIO" />
我有：
09-23 14:41:05.531: ERROR/AndroidRuntime(1718): Uncaught handler: thread main exiting due to uncaught exception 09-23 14:41:05.551: ERROR/AndroidRuntime(1718): java.lang.RuntimeException: setAudioSource failed. 09-23 14:41:05.551: ERROR/AndroidRuntime(1718): at android.media.MediaRecorder.setAudioSource(Native Method)
如何正确录制语音？
打开“ AndroidManifest.xml ” - >
加
<uses-permission android:name="android.permission.RECORD_AUDIO" />
我知道这是一个非常古老的问题，但在Android Marshmallow中，您必须继续“设置>应用程序>您的应用程序>权限”并且可以使用麦克风权限。
如果您在Android M上运行，那么您需要申请权限才能在第一次运行时录制音频。 要做到这一点，请询问用户是否可以在应用程序启动时录制音频：
private static final int MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE = 29;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (mContext.checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.RECORD_AUDIO},
MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE);
} else {
Log.d("Home", "Already granted access");
initializeView(v);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE: {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Log.d("Home", "Permission Granted");
initializeView(v);
} else {
Log.d("Home", "Permission Failed");
Toast.makeText(getActivity().getBaseContext(), "You must allow permission record audio to your mobile device.", Toast.LENGTH_SHORT).show();
getActivity().finish();
}
}
// Add additional cases for other permissions you may have asked for
}
}
