Android 开机直接运行app并当做手机桌面的实例

`public class Receiver extends BroadcastReceiver {
 @Override
 public void onReceive(Context context, Intent intent) {

 Log.e("broadCastReceiver","onReceiver...");

 try {
  Intent mBootIntent = new Intent(context, MainActivity.class);
  // 下面这句话必须加上才能开机自动运行app的界面
  mBootIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  context.startActivity(mBootIntent);
 } catch (Exception e) {
  e.printStackTrace();
 }
 }

}`
