Question

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);

Answer 1

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) {

    }
