以下是完整的工作示例代码

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.practice" android:versionCode="1" android:versionName="1.0">
    <uses-sdk android:minSdkVersion="4" />

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".AutoStartExampleActivity"
            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="AutoStart"></receiver>

        <receiver android:name=".AutoStart">

package com.practice;

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

public class AutoStart extends BroadcastReceiver
{

    public void onReceive(Context context, Intent intent)
    {
        System.out.println ( "Application Started" );
        // put your TimerTask calling class here

        try
        {
            Intent myIntent = new Intent ( context, AutoStartExampleActivity.class );
            myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(myIntent);
        }
        catch ( Exception e )
        {
            System.out.println ( " Error while Starting Activity " + e.toString() );
        }
