Android InstantApp:前台服务 [英] Android InstantApp: Foreground service

问题描述

无法在 InstantApp 功能模块中使用前台服务.低于运行时安全异常.

Unable to use foreground service inside InstantApp feature module. Getting below runtime security exception.

java.lang.RuntimeException:无法启动活动ComponentInfo{..XYZActivity}:java.lang.SecurityException:方法类 android.app.ActivityManagerProxy.getServices 不可用于免安装应用

java.lang.RuntimeException: Unable to start activity ComponentInfo{..XYZActivity}: java.lang.SecurityException: Method class android.app.ActivityManagerProxy.getServices not available to instant apps

Android 文档说，

Android document says,

受限功能:在用户不知情的情况下在设备上运行.前台服务可用.免安装应用只能通过支持应用链接的活动启动，因此服务、内容提供商或广播接收器将无法启动您的应用.

Restricted features: Run on the device without users being aware. Foreground services are available. Instant apps can only be started through activities that support App Links, so services, content providers or broadcast receivers won't be able to start your app.

代码:

// Starting service
getAppContext().startService(new Intent(getAppContext(), FirebaseAuthService.class));


// Foreground service class
public class FirebaseAuthService extends Service {

    private static final String TAG = "FirebaseAuthService";
    private boolean isRunning = false;

    private String mUserId;
    private FirebaseAuth mAuth;

    @Override
    public void onCreate() {
        Log.d(TAG, "Service onCreate");

        startForeground();
        isRunning = true;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.i(TAG, "Service onStartCommand");

        new Thread(new Runnable() {
            @Override
            public void run() {
                myTask();
            }
        }).start();

        return Service.START_STICKY;
    }


    @Override
    public IBinder onBind(Intent arg0) {
        Log.i(TAG, "Service onBind");
        return null;
    }

    @Override
    public void onDestroy() {
        isRunning = false;
        Log.i(TAG, "Service onDestroy");
    }

    private void startForeground() {
        Intent notificationIntent = new Intent(this, HomeActivity.class);

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

        Notification notification = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.noti_logo)
                .setContentTitle("Title")
                .setContentText("Preparing...")
                .setContentIntent(pendingIntent).build();

        startForeground(1337, notification);
    }

    private void myTask() {
         // At end
        // Stop service once it finishes its task
        stopSelf();
    }
}

推荐答案

您的代码是正确的，但由于 Instant Apps 主管中的一个已知问题，前台服务目前无法运行.

Your code is correct but Foreground services are not working at the moment due to a known issue in Instant Apps supervisor.
