Android开机自启动 .

1.定义一个BroadcastReceiver

public class BootReceiver extends BroadcastReceiver {
    public void onReceive(Context ctx, Intent intent) {
        Log.d("BootReceiver", "system boot completed");
        //start activity
        String action="android.intent.action.MAIN";
        String category="android.intent.category.LAUNCHER";
        Intent myi=new Intent(ctx,CustomDialog.class);
        myi.setAction(action);
        myi.addCategory(category);
        myi.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        ctx.startActivity(myi);
        //start service
        Intent s=new Intent(ctx,MyService.class);
        ctx.startService(s);
    }
}

public class BootReceiver extends BroadcastReceiver { public void onReceive(Context ctx, Intent intent) { Log.d("BootReceiver", "system boot completed"); //start activity String action="android.intent.action.MAIN"; String category="android.intent.category.LAUNCHER"; Intent myi=new Intent(ctx,CustomDialog.class); myi.setAction(action); myi.addCategory(category); myi.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); ctx.startActivity(myi); //start service Intent s=new Intent(ctx,MyService.class); ctx.startService(s); } }  

2.配置Receiver的许可,允许接收系统启动消息，在AndroidManifest.xml中：

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

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

3.配置Receiver,可以接收系统启动消息，在AndroidManifest.xml中

<receiver android:name=".app.BootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
        <category android:name="android.intent.category.HOME" />
    </intent-filter>
</receiver>

<receiver android:name=".app.BootReceiver"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED"/> <category android:name="android.intent.category.HOME" /> </intent-filter> </receiver>  

4.启动模拟器，可以看到系统启动后，弹出一个对话框。
