如何授予Android Shell用户更多权限？

W/AudioRecord( 4226): AUDIO_INPUT_FLAG_FAST denied by client
W/ServiceManager(  207): Permission failure: android.permission.RECORD_AUDIO from uid=2000 pid=4226
E/        (  207): Request requires android.permission.RECORD_AUDIO
D/PowerManagerService(  964): handleSandman: canDream=false, mWakefulness=Asleep
E/AudioFlinger(  207): openRecord() permission denied: recording not allowed
E/AudioRecord( 4226): AudioFlinger could not create record track, status: -1
E/libOpenSLES( 4226): android_audioRecorder_realize(0x453430) error creating AudioRecord object
W/libOpenSLES( 4226): Leaving Object::Realize (SL_RESULT_CONTENT_UNSUPPORTED)

我也尝试用pm grant授予shell：

pm grant "com.android.shell" android.permission.RECORD_AUDIO
pm grant "com.android.shell" android.permission.RECORD_AUDIO
pm grant "com.android.shell" android.permission.RECORD_AUDIO
Operation not allowed: java.lang.SecurityException: Package com.android.shell has not requested permission android.permission.RECORD_AUDIO

更改/system/etc/permissions/platform.xml也不起作用.

我可以在Android Shell中调试OpenSLES演示吗？我如何在shell中获得更多许可.

我必须为每个实验代码片段创建一个jni和java项目,并在更改某些C接口时一起对其进行修改吗？

我可以从外壳程序的命令工具中直接访问RECORD_AUDIO,CAMERA吗？

>每当我需要RECORD_AUDIO权限时,我都会检查我是否拥有它：

private boolean hasRecordAudioPermission(){
    boolean hasPermission = (ContextCompat.checkSelfPermission(this,
        Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED);

    log("Has RECORD_AUDIO permission? " + hasPermission);
    return hasPermission;
}

>如果我没有,请提出要求

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 (ActivityCompat.shouldShowRequestPermissionRationale(this,
            requiredPermission)) {

        showToast("This app needs to record audio through the microphone....");
    }

    // request the permission.
    ActivityCompat.requestPermissions(this,
            new String[]{requiredPermission},
            PERMISSIONS_REQUEST_RECORD_AUDIO);
}

@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {

    // This method is called when the user responds to the permissions dialog
}
