AlarmManager不会触发待处理的意图

本文介绍了AlarmManager不会触发待处理的意图的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我尝试将AlarmManager与BroadcastReceiver一起使用. 我的问题是我没有从AlarmManager收到意图火. 我没有接到Log.i("test", "test")

I try to use AlarmManager with BroadcastReceiver. My problem is that I dont get the intent fire from the AlarmManager. Im not getting any call from Log.i("test", "test")

这是我的代码:

public void activityCheck() { Intent intent = new Intent(this.getApplicationContext(), com.example.workoutlog.UsageCheckService.class); intent.putExtra("nofitication", "nofitication"); PendingIntent service = PendingIntent.getService(this, 0, intent, 0); AlarmManager m = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE); Calendar time = Calendar.getInstance(); time.setTimeInMillis(System.currentTimeMillis()); Log.i("Yo", "Yo"); m.setRepeating(AlarmManager.RTC, time.getTimeInMillis(), 1000*60, service); }

我的BroadcastReceiver类

My BroadcastReceiver class

public class UsageCheckService extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub Log.i("test", "test"); } }

在我的清单上

<receiver android:name="com.example.workoutlog.UsageCheckService" > </receiver>

推荐答案

如果手机处于睡眠状态，则必须将其唤醒.

If the phone is in sleep state, you will have to wake it up.

尝试一下:

这是工作代码.它每10分钟唤醒一次CPU，直到手机关闭.

添加到Manifest.xml:

Add to Manifest.xml:

... <uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission> ... <receiver android:process=":remote" android:name="Alarm"></receiver> ...

代码:

package YourPackage; import android.app.AlarmManager; import android.app.PendingIntent; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.PowerManager; import android.widget.Toast; public class Alarm extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, ""); wl.acquire(); // Put here YOUR code. Toast.makeText(context, "Alarm !!!!!!!!!!", Toast.LENGTH_LONG).show(); // For example wl.release(); } public void SetAlarm(Context context) { AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent i = new Intent(context, Alarm.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 60 * 10, pi); // Millisec * Second * Minute } public void CancelAlarm(Context context) { Intent intent = new Intent(context, Alarm.class); PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0); AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); alarmManager.cancel(sender); } }

通过服务设置警报:

package YourPackage; import android.app.Service; import android.content.Context; import android.content.Intent; import android.os.IBinder; public class YourService extends Service { Alarm alarm = new Alarm(); public void onCreate() { super.onCreate(); } public void onStart(Context context,Intent intent, int startId) { alarm.SetAlarm(context); } @Override public IBinder onBind(Intent intent) { return null; } }

如果要设置在电话启动时重复发出警报:

向Manifest.xml添加权限:

Add permission to Manifest.xml:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission> ... <receiver android:name=".AutoStart"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED"></action> </intent-filter> </receiver> ...

并创建新类:

package YourPackage; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class AutoStart extends BroadcastReceiver { Alarm alarm = new Alarm(); @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) { alarm.SetAlarm(context); } } }
