##需求背景： 要对apk进行管理，但是在不安装的情况下，我们需要拿到这个apk应用的名称，也就是安装好后，现实在Launcher里的名称。

##怎么获取未安装应apk的名字呢（label） 主要的代码如下：

    //Here is the main code

    //First we should get the dir of the apk.
    //By the way,please remember to add the uses-permission READ_EXTERNAL_STORAGE into the manifests file.
    String apkPath = "/storage/sdcard0/Download/test.apk";//Just an example,please replace it as yours.

    //We can get the label name by the path,but we need to get the packageManager first;
    PackageManager  pm = this.getPackageManager();

    //Get the packageInfo
    PackageInfo pi = pm.getPackageArchiveInfo(apkPath, PackageManager.GET_ACTIVITIES);

    //Set the source and public source dir.
    pi.applicationInfo.sourceDir = apkPath;
    pi.applicationInfo.publicSourceDir = apkPath;

    //Now,we get the app name but we haven't install.
    String appName = (String) pi.applicationInfo.loadLabel(pm);

    //Out put the name
    System.out.println("appName ==== " + appName);

手机上的apk路径是演示的路径，那么我们把程序跑起来以后呢，就可以看得到这样的结果啦：

    I/System.out: appName ==== 滴答表盘

然而我并没有安装这个apk，但是小手一抖，还是拿到了，对吧！ 你也试试吧，你一定可以的！
