Android 前台服务没有';不要在奥利奥跑步
我有一个前台服务可以在我的手机(Android 7.0)上运行,但它不能在朋友的手机(Android 8.0)上运行。我也在Android studio模拟器上测试它,在8.0版上也有同样的问题。我已经实现了if-else检查,看看它是否是Android 8.0,这样我就可以调用startForegroundService()还是什么都没有 我这样称呼它:Android 前台服务没有';不要在奥利奥跑步,android,android-8.0-oreo,foreground-service,Android,Android 8.0 Oreo,Foreground Service,我有一个前台服务可以在我的手机(Android 7.0)上运行,但它不能在朋友的手机(Android 8.0)上运行。我也在Android studio模拟器上测试它,在8.0版上也有同样的问题。我已经实现了if-else检查,看看它是否是Android 8.0,这样我就可以调用startForegroundService()还是什么都没有 我这样称呼它: //Start foreground service Intent intent = new Intent(this, MyFor
//Start foreground service
Intent intent = new Intent(this, MyForeGroundService.class);
intent.setAction(MyForeGroundService.ACTION_START_FOREGROUND_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
startForegroundService(intent);
}else{
startService(intent);
}
这是我的前台服务:
public class MyForeGroundService extends Service implements LocationListener {
public MyForeGroundService() {
}
@Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
@Override
public void onCreate() {
super.onCreate();
wakeLock();
}
@SuppressLint("InvalidWakeLockTag")
public void wakeLock() {
pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
assert pm != null;
wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "partialwl");
wl.acquire();
}
public void stopWakeLock() {
wl.release();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent != null) {
String action = intent.getAction();
switch (action) {
case ACTION_START_FOREGROUND_SERVICE:
wakeLock();
startForegroundService();
break;
case ACTION_STOP_FOREGROUND_SERVICE:
stopWakeLock();
stopForegroundService();
break;
case ACTION_PLAY:
Intent openMap= new Intent(this,Map.class);
startActivity(openMap);
break;
case ACTION_PAUSE:
break;
}
}
return START_STICKY;
}
/* Used to build and start foreground service. */
private void startForegroundService() {
Log.d(TAG_FOREGROUND_SERVICE, "Start foreground service.");
// Create notification default intent.
Intent intent = new Intent(this,Map.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
// Create notification builder.
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
//Go back to Map activity if user press at the notification
builder.setContentIntent(pendingIntent)
.setContentTitle("gEKOning...")
.setContentText("Tap to open gEKOn app");
builder.setWhen(System.currentTimeMillis());
builder.setSmallIcon(R.mipmap.ic_launcher);
Bitmap largeIconBitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
builder.setLargeIcon(largeIconBitmap);
// Make the notification max priority.
builder.setPriority(Notification.PRIORITY_MAX);
// Make head-up notification.
builder.setFullScreenIntent(pendingIntent, true);
// Build the notification.
Notification notification = builder.build();
// Start foreground service.
startForeground(1, notification);
}
private void stopForegroundService() {
Log.d(TAG_FOREGROUND_SERVICE, "Stop foreground service.");
// Stop foreground service and remove the notification.

}
您需要定义一个通知通道。这样就行了
private void createNotificationChannel() {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = getString(R.string.channel_name);
String description = getString(R.string.channel_description);
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);
channel.setDescription(description);
// Register the channel with the system; you can't change the importance
// or other notification behaviors after this
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}}
这个答案应该对你有帮助:@HedeH这个频道名是什么?我从哪里知道这个频道名是什么?没关系,只是安卓可以管理通知。如果您想了解更多,可以阅读有关通知渠道的内容:@HedeH非常感谢!很好!还有一个问题。我想实现我自己的标题、文本和图像,我还想在用户按下通知打开应用程序时实现。现在,如果用户按下应用程序,它会打开设置。有什么想法吗?它会打开设置,因为您没有指定
挂起内容
,标题
等。。因此,系统正在为您创建通知。您需要将内容添加到通知.Builder
。看看这里:包括我在内的一些人感到困惑,当他们在模拟器中测试通知时,FCM不工作。我在Nexus5虚拟设备上测试。我没有意识到它是在安卓O上运行的。很好
