Question

我试图让我的应用程序在指定的时间运行，但我无法让它运行。我可以在运行adb shell dumpsys alarm时看到待处理的警报，并且每次运行AlarmActivity时警报都会增加。

我添加了adb shell dumpsys alarm输出，我们可以看到警报。我看不出有什么问题谢谢你的帮助

这里有我的AlarmActivity代码：

package net.dradge.alarm;

import java.text.DateFormat;
import java.util.Calendar;
import java.util.Date;
import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class AlarmActivity extends Activity{
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.main);
    }

    protected void onResume(){
        super.onResume();
        this.setAlarm();
    }

    public class AlarmReceiver extends BroadcastReceiver{
        public void onReceive(Context context, Intent intent){
            Log.w("net.dradge.alarm", "Alarm received");
            AlarmActivity.this.setAlarm();
        }
    }

    private synchronized void setAlarm(){
        Calendar date = Calendar.getInstance();

        AlarmManager manager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
        Intent alarmIntent = new Intent(this, AlarmReceiver.class);
        PendingIntent operation = PendingIntent.getBroadcast(AlarmActivity.this, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        manager.set(AlarmManager.RTC_WAKEUP, date.getTimeInMillis() + 30 * 1000, operation);

        DateFormat df = DateFormat.getDateTimeInstance();
        Log.w("net.dradge.alarm", "Alarm set to " + df.format(new Date(date.getTimeInMillis() + 30 * 1000)));
    }
}

这里有Manifest代码：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="net.dradge.alarm"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".AlarmActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver android:name=".AlarmActivity.AlarmReceiver"></receiver>
    </application>

</manifest>

adb shell dumpsys警报当前的警报管理器状态：

Answer 1

我认为您的接收器应该声明为

<receiver android:name=".AlarmActivity$AlarmReceiver"></receiver>

因为它是一个内部阶级。

Android Alarm从未收到过
