当 minifyEnabled 设置为 true 时，React Native Android 应用程序在发布版本中崩溃

Question

在我的应用程序级别 build.gradle 文件中，我启用了缩小功能

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

然后，当我在 Android 设备中安装 apk 时，应用程序崩溃了。

当我从 Android Studio 检查 logcat 时，出现此错误。

FATAL EXCEPTION: mqt_native_modules

正如类似问题中所建议的，我检查了 RNQBSettingsModule 的来源。

我发现的是这个

因此，我将以下代码添加到 android/app/proguard-rules.pro 文件中，以免混淆这个特定的包。

-keep class com.quickblox.reactnative.settings.** {*;}

但这并不能解决问题

Answer 1

我通过更新

android/app/proguard-rules.pro

文件修复了崩溃，如下所示。

为此，我遵循了

quickblox-android-sdk

的自述文件。

https://github.com/QuickBlox/quickblox-android-sdk/blob/master/README.md#customize-proguard-in-android-studio

上述步骤未记录在

quickblox-react-native-sdk

中。所以，我必须对比赛进行一些小改动。

# Adding minifyEnabled caused runtime crashes in the release build. To fix that I have added proguard rules relating to quickblox
