这是我的code调用mxplayer，但它没有工作，为什么？

 意图myIntent;
PackageManager经理= getPackageManager（）;
myIntent = manager.getLaunchIntentForPackage（com.mxtech.videoplayer.ad）;
startActivity（myIntent）;
 

解决方案

MX播放器的开发者记录其包装命名空间此处的 https://sites.google.com/site/mxvpen/api

所以，如果你已经安装了专业版，您需要使用另一个名字。

  [包装]
com.mxtech.videoplayer.pro  - 专业版
com.mxtech.videoplayer.ad  - 免费版。
 

此外更可以捕获该异常的情况下，将MX播放器没有安装在系统上：

 意图myIntent;
    PackageManager下午= getPackageManager（）;
    尝试 {
        myIntent = pm.getLaunchIntentForPackage（YourPackageName）;
        如果（NULL！= myIntent）
            this.startActivity（myIntent）;
    }赶上（ActivityNotFoundException E）{

    }
 

here is my code to call mxplayer but it didn't work, why ?

Intent myIntent ;
PackageManager manager = getPackageManager();
myIntent = manager.getLaunchIntentForPackage("com.mxtech.videoplayer.ad");
startActivity(myIntent);

The developer of MX Player documented its package namespaces here: https://sites.google.com/site/mxvpen/api

So if you have installed the pro version, you need to use another name.

[Package]
com.mxtech.videoplayer.pro  - Pro Edition
com.mxtech.videoplayer.ad - Free Edition.

Further more you can catch the exception for the case, that the MX Player isn't installed on the system:

Intent myIntent;
    PackageManager pm = getPackageManager();
    try {
        myIntent = pm.getLaunchIntentForPackage(YourPackageName);
        if (null != myIntent)
            this.startActivity(myIntent);
    } catch (ActivityNotFoundException e) {

    }
