【问题描述】：

我的 android 应用程序在颤振中没有从 release.apk 中的 api 获取数据，但在调试模式或模拟器中工作正常，我尝试了一切我还在我的 AndroidManifest.xml 代码中添加了互联网权限，但对我没有任何作用。请解决我对flutter和android开发不熟悉的问题。

【问题讨论】：

谢谢..请回答我的问题

你有没有找到解决办法。我也陷入了同样的境地？

【参考方案1】：

请先隐藏您的 api 密钥。 api不工作一定是因为api键。你需要不同的。关注这个

Android: automatically choose debug/release Maps v2 api key?

【参考方案2】：

我通过在 buildTypes 下的 android/app/build.gradle 文件中添加 shrinkResources false 和 minifyEnabled false 解决了这个问题

buildTypes 
    release 
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        shrinkResources false
        minifyEnabled false
        signingConfig signingConfigs.debug
