ProGuard的缺少类型参数 [英] proguard Missing type parameter

问题描述

我试图混淆的Andr​​oid应用我的code与 ProGuard的。但是，这是我的应用程序后，给予例外，在运行：

i try obfuscate my code of android app with ProGuard. But after this my app give exception at running:

11-15 01:46:26.818: W/System.err(21810): java.lang.RuntimeException: Missing type parameter.
11-15 01:46:26.828: W/System.err(21810):    at da.<init>(Unknown Source)
11-15 01:46:26.828: W/System.err(21810):    at gc.<init>(Unknown Source)
11-15 01:46:26.828: W/System.err(21810):    at fx.f(Unknown Source)
11-15 01:46:26.828: W/System.err(21810):    at com.yourshows.activity.UnwatchedActivity.onResume(Unknown Source)

我查了映射文件，并发现这一点：

I checked a mapping file and found this:

com.google.gson.reflect.TypeToken -> da:

我认为这是线在我的应用程序，如：

I think it's lines in my app like:

        Type mapType = new TypeToken<Map<Integer, WatchedEpisodes>>(){}.getType(); // define generic type
        jsData = gson.fromJson(r, mapType);

我不明白什么样的结论，我应该怎么办？不要使用变量名少于三个字符或什么？

I can not understand what conclusions should I do? Do not use variable name less then three characters or what?
