Android 安卓：警报未启动服务

要求：反复启动后台服务

设计：使用

AlarmManager

我所做的：

<service
    android:name=".MyService"
    android:exported="false" >
</service>

AlarmManager alarm = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, MyService.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), SERVICE_ALARM_INTERVAL, pendingIntent);

问题：未执行

Toast

消息和

Log

打印

我做错了什么

谢谢，

试试这个

AndroidManifest.xml

<receiver android:name=".AlarmReceiver">
   <intent-filter>
        <action android:name="com.example.project.AlarmReceiver" />
   </intent-filter>
</receiver>

AlarmReceiver.java

Intent intent = new Intent(context, AlarmReceiver.class);

intent.setAction("com.example.project.AlarmReceiver");
intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);

AlarmManager alarmMgr = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);

alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), SERVICE_ALARM_INTERVAL, pendingIntent);

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Alarm received!!!!!", Toast.LENGTH_LONG).show();
    }

}

将使用如上所示的广播接收器调用AlarmManager

AndroidManifest.xml

<receiver android:name=".AlarmReceiver">
   <intent-filter>
        <action android:name="com.example.project.AlarmReceiver" />
   </intent-filter>
</receiver>

AlarmReceiver.java

Intent intent = new Intent(context, AlarmReceiver.class);

intent.setAction("com.example.project.AlarmReceiver");
intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);

AlarmManager alarmMgr = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);

alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), SERVICE_ALARM_INTERVAL, pendingIntent);

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Alarm received!!!!!", Toast.LENGTH_LONG).show();
    }

}

将使用如上所示的广播接收器调用AlarmManager，您正在使用的是

PendingEvent.getBroadcast（）

-这将触发广播。如果要触发服务，则需要使用。

您使用的是

pendingent.getBroadcast（）

-这会触发广播。如果要触发服务，您需要使用。

谢谢，实际上这是一种不同的设计，但它正在工作！谢谢，实际上这是一种不同的设计，但它的工作！
