flutter 應用程序未從發行版 apk 中啟動
[英]flutter app not launching in from release apk
問題描述
flutter 應用程序在 android 調試、ios 調試和 ios 版本中運行良好但隨着 android 版本（ flutter build apk ）它只是不啟動。
我試過的：
按照此處的建議，將 gradle 版本從
4.1.3降低到3.6.2。使用
no-shrink標志運行（flutter build apk --no-shrink）。在
android/app/build.gradleshrinkResources和minifyEnabled設置為false
這是我的flutter doctor -v output：

它目前是一般的 flutter sdk 和 android 架構支持問題，等待永久修復....
但是這個abifilters解決方案為我解決了在模擬器藍色堆棧上模擬 LG 手機的問題。在項目的build.gradle android 文件中的defaultConfig標記中添加ndk 代碼
**
android {
//...
defaultConfig {
ndk {
// Filter for architectures supported by Flutter.
abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86_64'
}
}
}
**
不知道其他手機是否有缺點，但我會在我們推出時更新這個線程，看看我們的客戶再次遇到相同問題的手機正在使用它
編輯，還將以下行添加到settings.gradle的末尾：要過濾更多的文件。此代碼將在文件夾 x86_64、arm64-v8a 和 armeabi-v7a 上生成文件libflutter.so 。 對於設備 x86，然后模擬 arm 這是有問題的設備..
gradle.beforeProject({ project->
if (project.hasProperty("target-platform") &&
!project.getProperty("target-platform").split(",").contains("android-arm")) {
project.setProperty("target-platform", "android-arm,android-arm64")
}
})
