【中文标题】更新 Android Studio 3.5 获得 proguard 警告

【英文标题】：Update Android studio 3.5 getting proguard warnings

【发布时间】：2019-12-30 11:02:56

【问题描述】：

自从我将 android Studio 从 3.4 更新到 3.5 后，我在项目中遇到了错误。错误列表如下，似乎 proguard 文件中缺少规则。

但是一旦我提出这些规则：

-dontnote androidx.**
-dontwarn androidx.**

项目正在无限构建，不会完成。我等了 30-40 分钟，根本没有结果。 （通常项目构建时间为4-5分钟）

         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.

这些是保护规则：

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in <android sdk path>/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.

【参考方案1】：

尝试设置

android 
     compileSDKVersion 29

【讨论】：

您应该尝试解释这有什么帮助以及问题所在。

不知道为什么，但这对我有用，您能解释一下为什么 Sdk 29 有效而 28 无效吗？

之所以有效，是因为 androidx 库太新了，以至于它们引用了在级别 29 中添加的 API。当 proguard 运行时，它会抱怨对它不知道的类的引用，因为这表明你可能是产生一个糟糕的构建。当您使用 andoidx 库针对低于 29 的 API 级别编译项目时，proguard 无法找到所有引用。所以选择是帮助 proguard 用这个答案解决引用，或者告诉 proguard 用 dontwarn 答案保持安静。

@satur9nine 它解决了警告但发布了 apk 崩溃。并且崩溃日志是 android.view.InflateException: Binary XML file line #7: Binary XML file line #6: Error inflating class TextView 有什么线索吗？

@GiruBhai 建议您使用完整的堆栈跟踪提出一个新问题。仅凭那一小部分信息不足以诊断。

【参考方案2】：

就用这个吧：

-dontwarn androidx.appcompat.widget.**

别忘了删除：

-dontnote androidx.**
-dontwarn androidx.**

【参考方案3】：

更新 gradle 插件版本

buildscript 
 repositories 

    google()
    jcenter()


dependencies 
    classpath 'com.android.tools.build:gradle:3.5.3'
    classpath 'com.google.gms:google-services:4.3.3'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
