/**      * 判断手机是否ROOT      */      public boolean isRoot() {              boolean root = false;              try {              if ((!new File("/system/bin/su").exists())                      && (!new File("/system/xbin/su").exists())) {                  root = false;              } else {                  root = true;              }              } catch (Exception e) {          }              return root;      }

上面返回的参数就知道手机是否具有ROOT权限了。

向ROOT权限发送请求信息,以获取ROOT权限

此方法不涉及底层, 这种方式需要用户点击确认才可以获取.
