项目需要android开机自动启动一个app的界面,网上找了些资料,证实可用:

首先是在你要启动的app的AndroidManifest.xml文件里面加下面一段代码(注意是加在application标签内):

<receiver android:enabled="true" android:name=".BootUpReceiver"    

        android:permission="android.permission.RECEIVE_BOOT_COMPLETED">    

        <intent-filter>    

                <action android:name="android.intent.action.BOOT_COMPLETED" />    

                <category android:name="android.intent.category.DEFAULT" />    

        </intent-filter>    

</receiver>    

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

之后在项目里面创建一个BootUpReceiver的类(MyActivity是你自己的app的main activity):
public class BootUpReceiver extends BroadcastReceiver{    
        public void onReceive(Context context, Intent intent) {    
                Intent i = new Intent(context, MyActivity.class);        
                i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);    
                context.startActivity(i);        
        }    
}

之后编译运行,再启动系统的时候,app就可以在系统启动完成之后自动运行啦
