Android 定时启动应用

使用AlarmManager和Receiver实现定时自动启动应用程序：

public class Main extends Activity {
        public final String MT_ACTION = "android.intent.action.START_MY_APP"; 
        Button bt;
    public void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        bt = (Button)findViewById(R.id.bt);
        bt.setOnClickListener(new View.OnClickListener() {
                        public void onClick(View v) {
                                Main.this.finish();
                        }
                });
        AlarmManager am = (AlarmManager)Main.this.getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(MT_ACTION);
        PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent, 1);
        am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+3500, pi);
    }
}

Manifext：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.vancl.startapp"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="8" />

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Main"
                  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="AlarmReceiver">  
               <intent-filter>  
                 <action android:name="android.intent.action.START_MY_APP"/>  
             </intent-filter>  
        </receiver> 
    </application>
</manifest>

Receiver：

package com.vancl.startapp;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class AlarmReceiver extends BroadcastReceiver {
        public void onReceive(Context context, Intent intent) {
                Intent it = new Intent();
                it.setClass(context, Main.class);
                it.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(it);	//接受到广播 启动应用
        }

}
