下面是完整的code：

Here is the complete code:

ArrayList<PackageInfo> res = new ArrayList<PackageInfo>();
PackageManager pm = ctx.getPackageManager();
List<PackageInfo> packs = pm.getInstalledPackages(0);

for(int i=0;i<packs.size();i++) {
    PackageInfo p = packs.get(i);
    String description = (String) p.applicationInfo.loadDescription(pm);
    String  label= p.applicationInfo.loadLabel(pm).toString();
    String packageName = p.packageName;
    String versionName = p.versionName;
    String versionCode = p.versionCode;
    String icon = p.applicationInfo.loadIcon(pm);
//Continue to extract other info about the app...
}

注意：此权限添加到清单文件：
