我收到了这个错误：

使用这段代码：

class Subscribe extends AsyncTask<String, Void, Result> {

        @Override
        protected Result doInBackground(String... s) {
            // ...

            Document test = Jsoup.parse("<html></html>"); // explodes here
        }
}

这仅适用于发布模式。我正在使用Jsoup 1.7.2。怎么了？我怎么能看到错误在“...... 17以上”中崩溃，因为我猜这里的线索就在那里......

这与error using AsyncTask only when running release apk... please help :(的问题相同，但没有答案。

这个让我好痛！

Answer 1

这确实是ProGuard的一个混淆问题（如果只在发布模式中存在问题，这是合乎逻辑的），我不得不将以下内容添加到proguard文件中：

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

使用AsyncTask和Jsoup发布APK时出错
