最近我将我的项目升级到26 Api级别。之后,报警经理不为我工作。我不知道问题是什么,但我猜警报根本不起作用,只要应用程序处于lolipop(> = M)以上的所有设备的后台。我已经解决了其他问题并且遵循了一些建议,例如'WakefulBroadcastReceiver',
以下是我的代码和相同的流程
- 每15分钟设置一次重复警报。
Intent dil = new Intent(getApplicationContext(), LocationSyncTaskReceiver.class);
PendingIntent dlpi = PendingIntent.getBroadcast(getApplicationContext(), 225566, dil, 0);
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
lFreq = 15;
if(Build.VERSION.SDK_INT>23)
am.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP,(System.currentTimeMillis()+5 * 60 * 1000L),dlpi);
else
am.setRepeating(AlarmManager.RTC_WAKEUP, 5 * 60 * 1000L, lFreq * 60 * 1000L, dlpi);
- 正在调用'WakefulBroadcastReceiver'。
public class LocationSyncTaskReceiver extends WakefulBroadcastReceiver {
private static final String TAG = LocationSyncTaskReceiver.class.getSimpleName();
@Override
public void onReceive(Context context, Intent intent) {
WakefulIntentService.acquireStaticLock(context);
Intent locationSync = new Intent(context, SyncLocationTracker.class);
startWakefulService(context,locationSync);
}
}
- 上面的代码调用'WakefulIntentService' - SyncLocationTracker
@Override
public void doWakefulWork(Intent intent) {
userService = UserServiceImpl.getInstance();
Log.d(TAG, "Data Tracker : doWakefulWork called");
if (userService.getLoggedInUser() != null) {
Log.d(TAG, "User is logged in so continuing sync ....");
WakefulIntentService.acquireStaticLock(getApplicationContext());
syncService = DataSyncServiceImpl.getInstance();
syncService.syncLocation();
} else {
Log.d(TAG, "User is not logged in so discarding sync ....");
stopSelf();
}
stopSelf();
}
- 'syncService.syncLocation();'终于做了一些计算和多个网络请求

更改您的if条件:
if(Build.VERSION.SDK_INT > 23)
为:
if(Build.VERSION.SDK_INT >= 23)

使用此库解决了它 Evernote job scheduler library
它使用JobScheduler
,GcmNetworkManager
或AlarmManager
,具体取决于您的Android操作系统版本。
Android Oreo的所有功能都向后兼容回到Ice Cream Sandwich。
JobRequest.Builder
类有许多额外选项,例如您可以指定所需的网络连接,定期作业,使用捆绑包传递一些额外内容,在重新启动后恢复作业或在准确的时间运行作业。
实施例
int jobId = new JobRequest.Builder(DemoSyncJob.TAG)
.setExecutionWindow(30_000L, 40_000L)
.setBackoffCriteria(5_000L, JobRequest.BackoffPolicy.EXPONENTIAL)
.setRequiresCharging(true)
.setRequiresDeviceIdle(false)
.setRequiredNetworkType(JobRequest.NetworkType.CONNECTED)
.setExtras(extras)
.setRequirementsEnforced(true)
.setUpdateCurrent(true)
.build()
.schedule();
