android - 谷歌.android.gms :play-services-oss-licenses not working after obfuscation

Question

我正在开发个人 Android 应用程序。混淆后无法启动OssLicensesMenuActivity。应用程序崩溃。它工作正常，没有混淆。

startActivity(new Intent(getContext(), com.google.android.gms.oss.licenses.OssLicensesMenuActivity.class));

这是我的发布配置:

release {
            minifyEnabled true
            debuggable true
            shrinkResources true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }

我将这一行添加到 proguard-rules.pro:

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

此外，我在官方指南中看不到 proguard 文档: https://developers.google.com/android/guides/opensource

只有我的应用程序的发布版本崩溃。以下错误来自 Logcat。

你能帮我看看为什么会出现这个错误，有什么解决办法吗？

好的，我发现了问题。我将可绘制资源保存在 res/raw/keep.xml 中。

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools"
    tools:shrinkMode="strict" 
    tools:keep="@drawable/*"/>

我删除了 tools:shrinkMode="strict" 并解决了问题。一切正常。
