flutter 应用程序未从发行版 apk 中启动

[英]flutter app not launching in from release apk

问题描述

flutter 应用程序在 android 调试、ios 调试和 ios 版本中运行良好但随着 android 版本（ flutter build apk ）它只是不启动。

我试过的：

  1. 按照此处的建议，将 gradle 版本从4.1.3降低到3.6.2 。

  2. 使用no-shrink标志运行（ flutter build apk --no-shrink ）。

  3. 在android/app/build.gradle shrinkResources和minifyEnabled设置为false

这是一个清楚地显示错误的视频

这是我的flutter doctor -v output：

它目前是一般的 flutter sdk 和 android 架构支持问题，等待永久修复....
但是这个abifilters解决方案为我解决了在模拟器蓝色堆栈上模拟 LG 手机的问题。在项目的build.gradle android 文件中的defaultConfig标记中添加ndk 代码

**

android {
    //...
    defaultConfig {
    ndk {
    // Filter for architectures supported by Flutter.
    abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86_64'
    }
    }
    }

**

不知道其他手机是否有缺点，但我会在我们推出时更新这个线程，看看我们的客户再次遇到相同问题的手机正在使用它

编辑，还将以下行添加到settings.gradle的末尾：要过滤更多的文件。此代码将在文件夹 x86_64、arm64-v8a 和 armeabi-v7a 上生成文件libflutter.so 。 对于设备 x86，然后模拟 arm 这是有问题的设备..

gradle.beforeProject({ project->
    if (project.hasProperty("target-platform") &&
            !project.getProperty("target-platform").split(",").contains("android-arm")) {
        project.setProperty("target-platform", "android-arm,android-arm64")
    }
})
