使用AlarmManager搭配Receiver应该可以实现定时自动启动应用程序：

import android.app.Activity;import android.app.AlarmManager;import android.app.PendingIntent;import android.content.Context;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class StartTiming extends Activity {        public final String MYACTION = "android.intent.action.STARTMYAP";        /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                Button btn = (Button)this.findViewById(R.id.btnClose);        btn.setOnClickListener(new OnClickListener(){            @Override            public void onClick(View v) {                // TODO Auto-generated method stub                StartTiming.this.finish();            }        });        AlarmManager am = (AlarmManager)this.getSystemService(Context.ALARM_SERVICE);        Intent intent = new Intent(MYACTION);        PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent, 1);        am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+15000, pi);//15秒钟以后启动    }}   

import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log;public class AlarmReceiver extends BroadcastReceiver{    public final String MYTAG = "Ray";    @Override    public void onReceive(Context context, Intent intent) {        // TODO Auto-generated method stub        Log.v(MYTAG,"I am AlarmReceiver,I receive the message");        Intent in = new Intent();        in.setClass(context, StartTiming.class);        in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        context.startActivity(in);    }}

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"      package="com.ray.test"      android:versionCode="1"      android:versionName="1.0" android:installLocation="auto">    <application android:icon="@drawable/icon" android:label="@string/app_name">        <activity android:name=".StartTiming"                  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.STARTMYAP"/>             </intent-filter>        </receiver>    </application></manifest>
