使用messbio flutter sdk时flutter构建apk文件错误

问题描述 投票:0回答:1

我正在开发一个 Flutter 项目,该项目使用 Mesibo SDK 来实现聊天功能。当尝试构建 APK 时,我遇到以下错误:

ERROR: Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in .
ERROR: R8: Missing class android.window.BackEvent (referenced from: void io.flutter.view.FlutterView.startBackGesture(android.window.BackEvent) and 1 other context)

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':flutter_inappwebview:minifyReleaseWithR8'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.R8Task$R8Runnable
   > Compilation failed to complete

* Try:

> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

我查看了中生成的missing_rules.txt文件 缺少的类是 android.window.BackEvent。

如何解决缺少的 android.window.BackEvent 类? 我是否需要添加特定的保留规则以防止 R8 剥离必要的类? Flutter SDK、Android SDK 版本和 Mesibo SDK 之间是否存在兼容性问题需要解决?

android flutter proguard android-r8

首先,进入 Android 文件夹,然后在应用程序目录中,找到

build.gradle
文件。

android {}
块内,设置以下内容:

buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        signingConfig signingConfigs.release
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

尝试这个配置。如果不起作用,请将以下两个属性设置为 false:

minifyEnabled true
shrinkResources true
