Question

我的应用程序在没有应用pro-guard-rules的情况下工作正常但出于安全考虑，我必须在我的应用程序中应用pro-guard-rules。当我应用规则并尝试运行我的应用程序时，我收到了这些错误。

Answer 1

好像你已经使用了凌空，并且使用proguard崩溃了你的应用程序。您可以将此行写入 proGuard 。

soup.findAll('td', {'class':['cell_ab team-home', 'cell_ab team-home  bold ']})

Answer 2

在您的应用程序中设置 Proguard Enabled 后，所有 Proguard 自定义规则取决于您是在应用程序的初始阶段还是中间或后期设置了 Proguard。

初始

<块引用>

这意味着，如果您在应用中集成任何第三方库，则如果该库提供或支持 proguard，规则将自行设置。

2.中后期

<块引用>

中间如果你在你的应用中设置了proguard并且你已经集成了许多第三方库，这意味着每个库都是没有规则的集成。然后，您需要在 proguard-rules.pro 文件中设置自定义规则。

app崩溃的场景有很多，一个是你使用的pojo类或者model类被proguard混淆了，需要在proguard-rules.pro文件中设置规则喜欢：

-keep class * {
     public private *;
}

或以其他方式根据要求使用以下代码

-dontwarn com.squareup.okhttp.**
-ignorewarnings
-keep class * {
    public private *;
}

-keep class com.google.android.gms.* { *; }
-dontwarn com.google.android.gms.**

-dontwarn org.xmlpull.v1.**
-dontnote org.xmlpull.v1.**
-keep class org.xmlpull.* { *; }
