推荐答案

您需要确定设备上安装的Skype的正确软件包名称是什么.

You need to figure out what is the right package name of the skype installed on your device.

PackageInfo pinfo = null;
pinfo = getPackageManager().getPackageInfo("com.skype.android", 0);

//getVersionCode is Deprecated, instead use getLongVersionCode().
long verCode = pinfo.getLongVersionCode();
//getVersionName is Deprecated, instead use versionName
String verName = pinfo.versionName;

您可以通过以下方法调用获取所有软件包并找出名称:

You can get all packages and find out name with the following method call:

List<PackageInfo> packages = getPackageManager().getInstalledPackages(PackageManager.GET_META_DATA);
