我正在"getActivity().getPackageName()“上崩溃，同时启用保护程序，但在不启用的情况下工作正常

Question

我正试图在游戏商店中使用带有包名的jsoup来获取我的应用程序的版本名。在生成时，通过启用prograud生成apk。它在获取包名时引发错误。

我正在使用这段代码从play store.中检索版本名

@Override
protected String doInBackground(Void... params) {

    String newVersion = null;
    try {
        Log.e("newVersion","newVersion");

        newVersion = Jsoup.connect("https://play.google.com/store/apps/details?id=" + getActivity().getPackageName() + "&hl=it")
                .timeout(30000)
                .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")
                .referrer("http://www.google.com")
                .get()
                .select("div[itemprop=softwareVersion]")
                .first()
                .ownText();

        Log.e("Jsoup.connect","Jsoup.connect");

        return newVersion;
    } catch (Exception e) {
        return newVersion;
    }
}

和我的错误是:

有人能告诉我如何解决这个错误吗？

Answer 1

这似乎是与Jsoup相关的Proguard错误。

在您的proguard文件中，尝试添加

-keeppackagenames org.jsoup.nodes

或

-keep public class org.jsoup.** {
public *;
}

Answer 2

尝试将newVersion变量声明为空字符串。

String newVersion = "";
