安裝發行版APK時出現“未安裝應用”錯誤

Question

對於密鑰庫配置，我已遵循以下步驟：

https://facebook.github.io/react-native/docs/signed-apk-android.html

當我嘗試在小米Mi5s（Android 6.0）設備中安裝APK文件時，出現“未安裝應用程序”錯誤。 在調試模式下沒有問題。

應用程序在運行時也會立即崩潰：

react-native run-android --variant=release

build.gradle文件：

apply plugin: "com.android.application"

import com.android.build.OutputFile

project.ext.react = [
    entryFile: "index.js"
]

apply from: "../../node_modules/react-native/react.gradle"

Answer 1

您需要先卸載該應用程序的所有其他版本，然后再安裝發行版APK。 請確保也未為其他用戶安裝該應用（Nexus 5也遇到了該問題）。 要為所有用戶卸載該應用程序，只需打開“應用程序設置”，然后為所有用戶選擇卸載，而不是將其向上拖動即可。

我對這個問題的解決方案是（Xiaomi Mi5s）：

• 從開發人員選項啟用的MUII優化（重新啟動）
• 從開發人員選項禁用MUII優化（重新啟動）

現在，我可以安裝APK的發行版本。
