如何修复它，以便可以编译APK

编辑：在我的proguard-rules.pro中添加了很多-dontwarn选项后，我还是得到了错误，我无法解决这些警告（有一些提示，但不是针对这些警告…）：

这些都是令人讨厌的清理。更好的库现在在库包中包含了它们的设置，但更老（或更懒）的库仍然没有。以下是我遵循的过程：

在开发过程中：

每当包含一个新库时，请确保检查其文档以了解其建议的ProGuard设置。（如果您对此很认真，那么可以避免以后的大量混乱和挖掘。）
如果库作者提供了一个AAR包（例如，在gradle依赖项行的末尾添加“@AAR”以获得完整的AAR，而不是更简单的JAR），那么他们甚至可能会在其中为您包含必要的ProGuard异常，这些异常将自动获取。（但根据我的经验，大多数作者还没有迈出这一步。）
每当在需要动态内省的自定义代码中添加新的名称空间/类时，例如在使用依赖项注入容器或JSON解析器时，请确保ProGuard设置为根据它们的包名拾取它们，或者自己一次添加一个类

生成并获取错误后：

从以前缀
```
error:
```
开头的所有行开始，然后是
```
warning:
```
（
```
注意：
```
行不会停止生成）
检查每行提到的名称空间。查找关联的库（例如
```
com.newrelic.SomeClass
```
可能是用于newrelic库的）。如果您找不到它，请尝试谷歌搜索，看看名称空间是否可以帮助您跟踪github
```
自述文件
```
，或者其他可能识别名称空间包含哪个库的内容。或者，检查Android Studio>Project>Packages>Libraries列表（第一次显示需要一段时间），并在那里跟踪名称空间。希望源代码可用，并在文件头注释中包含库的详细信息
查找该库的文档。希望它提到了必要的ProGuard更改
重建

图书馆文档中所说的所有更改都已存在，但仍会收到警告：

开始添加
```
-dontwarn
```
行。例如：
```
-dontwarn com.newrelic.*
```
（不要忘记双星号，这样它会忽略该名称空间下的整个树；否则一个星号只会忽略名称空间的直接子级。）
如果您开始使用blind
```
dontwarn
```
语句，您必须测试已编译的应用程序（APK）因为它现在很可能会在您身上崩溃，即使调试（非ProGuard）版本一直运行良好。确保测试您使用的所有库，检查logcat消息，并确保使用
```
dontwarn
```
练习您盲目跳过的所有代码路径/类

去他妈的，我老板说我已经发布了这个东西：

禁用ProGuard：-(

使用Android Studio中的“项目属性”对话框，或者编辑模块

build.gradle

文件并更改

Android{buildTypes{release{minifyEnabled true}}

并将其设置为false

你不会得到ProGuard的优化，APK会更大，代码也不会变得模糊。但是如果你的老板现在需要它，而你没有时间调试，那么禁用它也不会是世界末日

虽然你真的应该使用ProGuard。也许是时候和老板谈谈，让开发人员有更多的时间做我们需要做的无聊的技术工作了。

检查你收到的每一条警告/错误消息，我在ProGuard-rules.pro中添加了很多-dontwarn选项，跟随你的链接，但即使我没有警告，我也得到了e不管怎样，我更新了问题。。。
