Android 应用因混淆规则而崩溃
Android app crash with proguard-rules
我的应用程序在不应用 pro-guard-rules 的情况下工作正常，但出于安全目的，我必须在我的应用程序中应用 pro-guard-rules 。
我在应用规则并尝试 运行 我的应用程序时遇到这些错误。

似乎您使用过 volley 并且使用 proguard 使您的应用程序崩溃。
您可以将此行写入您的 proGuard.
-keep class org.apache.commons.logging.**
在您的应用程序中启用 Proguard 后，所有的 Proguard 自定义规则取决于您是否在应用程序初始阶段或中期或后期启用了 Proguard。
- 初始
It Means that if you integrate any third party library in your app , the rules gets set by its own if the library provides or supports proguard.
2.Middle 及更高版本
In Middle if you set up proguard in your app and you have already integrated many third party libraries , it means that every library is integrated without rules. Then at that you need to setup custom rules in your proguard-rules.pro file.
很多应用崩溃的情况depends.one是因为你使用的Pojo类或模型类被proguard混淆了，所以你需要在proguard中设置规则-rules.pro 文件
