You can use PackageManager for this purpose. I have successfully used this code in my app:

PackageInfo info = context.getPackageManager().getPackageArchiveInfo(apkPath, PackageManager.GET_META_DATA);
if(info != null) {
    ApplicationInfo appInfo = info.applicationInfo;
    if(Build.VERSION.SDK_INT >= 8) {
        appInfo.sourceDir = apkPath;
        appInfo.publicSourceDir = apkPath;
    }       
    String version = info.versionName;
    int vcode = info.versionCode;
}
