安卓开发中程序不能开机自启动问题

Question

1. 已经设置该程序为系统程序

2. 使用了广播方法`

   public class BootBroadcastReceiver extends BroadcastReceiver {
   static final String action_boot="android.intent.action.BOOT_COMPLETED";

   @Override
   public void onReceive(Context context, Intent intent) {
   System.out.println("TTTTTT");
   if (intent.getAction().equals(action_boot)){
   Intent ootStartIntent=new Intent(context,MainActivity.class);
   ootStartIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   context.startActivity(ootStartIntent);
   }
   }

3. 配置文件中权限和filter都已配置
   
   android:allowBackup="true"
   android:icon="@drawable/ic_launcher"
   android:label="@string/app_name"
   android:theme="@style/AppTheme" >
   android:name=".MainActivity"
   android:label="@string/app_name" >
   
   

           <category android:name="android.intent.category.LAUNCHER" />
       </intent-filter>
   </activity>
   <receiver android:name="com.example.test.BootBroadcastReceiver"> 
       <intent-filter> 
       <action android:name="android.intent.action.BOOT_COMPLETED" /> 
       <category android:name="android.intent.category.HOME" />
       </intent-filter>
   </receiver>
