如何向android shell用户授予android.permission.RECORD_AUDIO权限（） _permission

【如何向android shell用户授予android.permission.RECORD_AUDIO权限（）】弱龄寄事外，委怀在琴书。这篇文章主要讲述如何向android shell用户授予android.permission.RECORD_AUDIO权限？相关的知识，希望能为你提供帮助。
我用android NDK构建了一些命令行工具，并在/ data / local / tmp中执行它。现在它提示我“需要android.permission.RECORD_AUDIO”。它通常在AndroidManifest.xml中用于java应用程序，但如何将其授予android shell用户？
源代码如：

sp< AudioRecord> rec = new AudioRecord(AUDIO_SOURCE_MIC, 44100, AUDIO_FORMAT_PCM_16_BIT, AUDIO_CHANNEL_IN_MONO);

logcat的：

I/AudioFlinger( 3772): AudioFlinger's thread 0xf0e838c0 ready to run W/ServiceManager( 3772): Permission failure:android.permission.RECORD_AUDIO from uid=2000 pid=-1 E/( 3772): Request requires android.permission.RECORD_AUDIO E/AudioFlinger( 3772): openRecord() permission denied: recording not allowed E/AudioRecord(14132): AudioFlinger could not create record track, status: -1 --------- beginning of crash ...

答案在Lollipop之后，Android平台正在使用实时权限。如果您的应用在Marshmallow和版本之后运行，则应在Activity中授予您的权限。
请求权限之前：

if (Build.VERSION.SDK_INT > = Build.VERSION_CODES.M) { if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED) { // put your code for Version> =Marshmallow } else { if (shouldShowRequestPermissionRationale(Manifest.permission.RECORD_AUDIO)) { Toast.makeText(this, "App required access to audio", Toast.LENGTH_SHORT).show(); } requestPermissions(new String[]{Manifest.permission.RECORD_AUDIO }, REQUEST_CAMERA_PERMISSION_RESULT); }} else { // put your code for Version < Marshmallow }

在此之后，请覆盖此方法并输入您的代码：

@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if (requestCode == REQUEST_AUDIO_PERMISSION_RESULT) { if (grantResults[0] != PackageManager.PERMISSION_GRANTED) { Toast.makeText(getApplicationContext(), "Application will not have audio on record", Toast.LENGTH_SHORT).show(); } } }

另一答案

private void requestRecordAudioPermission() {String requiredPermission = Manifest.permission.RECORD_AUDIO; // If the user previously denied this permission then show a message explaining why // this permission is needed if (getActivity().checkCallingOrSelfPermission(requiredPermission) == PackageManager.PERMISSION_GRANTED) {} else {Toast.makeText(getActivity(), "This app needs to record audio through the microphone....", Toast.LENGTH_SHORT).show(); requestPermissions(new String[]{requiredPermission}, 101); }}@Override public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { if (requestCode == 101 & & grantResults[0] == PackageManager.PERMISSION_GRANTED) { // This method is called when thepermissions are given }}
