看了网上的几个 例子，也做了一个系统启动后直接运行activity的小程序

代码贴在下面：

首先是从BroadcastReceiver派生出一个新类，用来监听系统启动后发出的广播消息android.intent.action.BOOT_COMPLETED。

BootReceiver.java:

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

public class BootReceiver extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {
        

         if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED"))
         {
              Log.d("BootReceiver", "system boot completed");
              Intent newIntent = new Intent(context, FirstRun.class);
         newIntent.setAction("android.intent.action.MAIN"); //MyActivity action defined in AndroidManifest.xml

         newIntent.addCategory("android.intent.category.LAUNCHER");//MyActivity category defined in AndroidManifest.xml

         newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //If activity is not launched in Activity environment, this flag is mandatory to set

         context.startActivity(newIntent);

         //if you want to start a service, follow below method:


         /*******************************************************

            Intent service = new Intent(yourService.ACTION_START);
            service.setClass(context, yourService.class);
            context.startService(service);

 

我改成：

Intent i = new Intent(AutoRun.class.getName());
           i.setClass(context, AutoRun.class);

            context.startService(i);




         ******************************************************/
         }
     }
}

接下来这个类就是监听到系统启动完毕后，我们要运行的activity.
FirstRun.java

import android.app.Activity;
import android.os.Bundle;

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

当然，我们还要改配置文件，需要注意的是,在manifest.xml中需要加上
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>

Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android=""
      package="com.service.prac"
      android:versionCode="1"
      android:versionName="1.0">
      
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <receiver android:name=".BootReceiver"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </receiver>
        <activity android:name=".FirstRun">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="3" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
</manifest>
