如何保持android手机的CPU始终处于唤醒状态？
我已经坚持了好几天了。我需要每分钟执行一个函数。此功能从应用程序向服务器进行POST呼叫，并每分钟传输用户的位置。位置坐标传输几个小时，但是，几个小时后，位置坐标传输到服务器会自行停止。我正在使用WakefulBroadcastReceiver和IntentService来确保CPU保持清醒。我还利用Alarm来确保每分钟都执行该功能 这就是我的WakefulBroadcastReceiver的外观：如何保持android手机的CPU始终处于唤醒状态？,android,android-intent,broadcastreceiver,alarmmanager,intentservice,Android,Android Intent,Broadcastreceiver,Alarmmanager,Intentservice,我已经坚持了好几天了。我需要每分钟执行一个函数。此功能从应用程序向服务器进行POST呼叫，并每分钟传输用户的位置。位置坐标传输几个小时，但是，几个小时后，位置坐标传输到服务器会自行停止。我正在使用WakefulBroadcastReceiver和IntentService来确保CPU保持清醒。我还利用Alarm来确保每分钟都执行该功能 这就是我的WakefulBroadcastReceiver的外观： public class SimpleWakefulReceiver extends Wake

对于（int i=0；i首先，您的SimpleWakefulService看起来不是很wakefull，它应该是WakeLock，但它不是。例如，此类服务的示例如下所示：
下一件事是更新函数。它是在获取部分唤醒锁的上下文中调用的，但其中的线程是异步执行的，这意味着也是在释放唤醒锁之后。这就是导致问题的原因
解决方案是从更新函数中移动线程代码（不需要线程）要唤醒上述链接中的WikefulIntentService。我确信我会尽快卸载此类应用程序，因为它会很快吸干我的电池。我还能做些什么来每分钟获取用户的位置？非常感谢您的回复marcinj。我将实施它。如果您能查看编辑，我将非常感谢您（在问题的底部）和进一步的指导。@User11012 android可能会终止您的服务，您的实现非常占用资源-您一直保持wakelock，一旦不再需要，您应该立即释放wakelock。这就是为什么您应该遵循指南，这意味着使用AlarmManager每隔几分钟发布一次广播，然后从此广播调用WakefulIntentService。我应该做哪些更改，以便每1分钟发布一次广播（后调用）。此外，我是否只需要使用AlarmReceiver.java和WakefulIntentService.java，或者我还需要包括您在“demo”文件夹中编写的三个类。此外，需要每分钟执行的代码，我应该在何处添加这些代码。最重要的是，请原谅我提出的这些基本问题，我是一名新手开发人员，请尝试向像您这样的伟大人物学习开发。@User11012抱歉，我不太明白-您应该按照演示中的代码进行操作，即，时间间隔在AppListener.java中设置。
