我在AUDIO_RECORD权限上遇到了问题

简而言之：-AUDIO_RECORD权限始终返回false。

当用户启动应用程序（第一时间）时，它会显示许可请求消息对话框如果用户接受，则否认一切正常。下次用户打开应用程序时，我检查是否授予了权限，它返回了拒绝的权限，然后我再次请求权限。并在每次启动麦克风时进行录音。它返回被拒绝的权限，我必须再次请求权限。因此，每次我启动麦克风时，它都会返回拒绝权限。我的问题是该应用程序应在后台运行并从一个小部件开始记录，例如，但是启动权限请求后，该活动将放在最前面。

int permissionResult = PermissionChecker.checkSelfPermission(getApplicationContext(), Manifest.permission.RECORD_AUDIO);
    // Start listening to voices
    if (permissionResult == PermissionChecker.PERMISSION_DENIED || permissionResult == PermissionChecker.PERMISSION_DENIED_APP_OP) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions( new String[]{Manifest.permission.RECORD_AUDIO}, REQUEST_RECORD_AUDIO_PERMISSION);
        }
    } else if (ActivityCompat.shouldShowRequestPermissionRationale(this,
            Manifest.permission.RECORD_AUDIO)) {
        showPermissionMessageDialog();
    } else if (permissionResult == PermissionChecker.PERMISSION_GRANTED) {
     //granted.
    }


 private void showPermissionMessageDialog() {
    MessageDialogFragment
            .newInstance(getString(R.string.permission_message))
            .show(getSupportFragmentManager(), FRAGMENT_MESSAGE_DIALOG);
}

MessageDialogFragment

/**
 * A simple dialog with a message.
 *
 *  <p>The calling {@link android.app.Activity} needs to implement {@link
 * MessageDialogFragment.Listener}.</p>
 */
   public class MessageDialogFragment extends AppCompatDialogFragment {

public interface Listener {
    /**
     * Called when the dialog is dismissed.
     */
    void onMessageDialogDismissed();
}

private static final String ARG_MESSAGE = "message";

/**
 * Creates a new instance of {@link MessageDialogFragment}.
 *
 * @param message The message to be shown on the dialog.
 * @return A newly created dialog fragment.
 */
public static MessageDialogFragment newInstance(String message) {
    final MessageDialogFragment fragment = new MessageDialogFragment();
    final Bundle args = new Bundle();
    args.putString(ARG_MESSAGE, message);
    fragment.setArguments(args);
    return fragment;
}

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new AlertDialog.Builder(getContext())
            .setMessage(getArguments().getString(ARG_MESSAGE))
            .setPositiveButton(android.R.string.ok, (dialog, which) -> ((Listener) getActivity()).onMessageDialogDismissed())
            .setOnDismissListener(dialogInterface -> ((Listener) getActivity()).onMessageDialogDismissed())
            .create();
}

}

清单

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="....">

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

每次拒绝运行时权限都会返回
