1、The content of the adapter has changed but ListView did not receive a notification.

Make sure the content of your adapter is not modified from a background thread, but only from the UI thread.

Make sure your adapter calls notifyDataSetChanged() when its content changes

从提示可以看出一种情况是后台线程修改了数据源另一种是内容发生变化了，但没有调用notifyDataSetChanged 我是第二种情况

2、Gson 数据解析时尽量用

VersionInfo versionInfo1 = gson.fromJson(versionInfo, new TypeToken<VersionInfo>() {}.getType());

而不是 VersionInfo versionInfo1 = gson.fromJson(versionInfo,VersionInfo.class ); 因为后者的解析格式要求更为严格某些机型会报异常
