android adb 获取所有app 的uid

系统刚启动的时候，会对每个app分配一个uid，

最简单的获取方式就是通过adb ，不过限于eng或userdebug版

adb pull data/system/packages.list d:\

当然最合理的方式是通过PackageManager

public List getUids() {
       List uidList = new ArrayList();
       pm = getPackageManager();
       List packinfos = pm
               .getInstalledPackages(PackageManager.GET_UNINSTALLED_PACKAGES
                       | PackageManager.GET_PERMISSIONS);
       for (PackageInfo info : packinfos) {
           String[] premissions = info.requestedPermissions;
           if (premissions != null && premissions.length > 0) {
               for (String premission : premissions) {
                   if ("android.permission.INTERNET".equals(premission)) {
                       // System.out.println(info.packageName+"访问网络");
                       int uid = info.applicationInfo.uid;
                       Log.i("test", "uid = " + uid);
                       // String name = pm.getNameForUid(uid);
                       // // textName.setText(name);
                       // Log.i("test", "name = "+name);
                       uidList.add(uid);
                   }
               }
           }
       }
       return uidList;
   }
