Fix INSTALL_FAILED_UPDATE_INCOMPATIBLE When Installing Android APK via ADB After building your React Native Android release APK, you may encounter this error when installing it: adb: failed to install app-release.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Existing package signatures do not match newer version] This means the APK was built successfully, but Android refuses to install it because the app on your device was signed with a different certificate. Why This Happens Android requires that any update to an existing app must be signed with the same keystore as the original installation. Typically this happens when: You installed a debug build previously You switched keystores for your release build You changed your signing configuration If the signatures don’t match, Android will block the installation. How to Fix It Option 1: Uninstall the Existing App (Quick Fix) adb uninstall com.westminstershortercatechismqa adb install app-release.apk Onc...

解决 adb install 时 INSTALL_FAILED_UPDATE_INCOMPATIBLE 签名不匹配错误 在使用 React Native 构建 Android Release APK 后，通过 adb 安装时，可能会遇到如下错误： adb: failed to install app-release.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Existing package signatures do not match newer version] 这个问题并不是编译失败，而是 Android 安装机制阻止了不同签名的应用覆盖安装 。 为什么会出现这个错误？ Android 系统要求：同一个包名的 App，在更新时必须使用相同的签名证书。 如果你之前安装的是： Debug 版本（默认签名） 或者使用了不同的 Release Keystore 而现在你安装的是新的 Release APK（使用了不同签名），系统就会拒绝更新，从而出现此错误。 解决方法 方法 1：卸载旧应用（最简单） adb uninstall com.westminstershortercatechismqa adb install app-release.apk 卸载后再安装即可正常运行。 方法 2：使用统一的 Release Keystore 如果你希望以后可以直接覆盖安装（升级 App），需要保证每次构建 Release 都使用同一个 keystore。 在 android/app/build.gradle 中配置： android { signingConfigs { release { storeFile file("release.keystore") storePassword "your_password" keyAlias "your_alias" keyPassword "your_password" } } buildTypes { release { ...

React Native 使用 TypeScript + Hermes 时 Android Release 构建报错解决方案 如果你把 React Native 项目的入口文件从 index.js 改成了 index.ts ，然后在构建 Android Release 版本时失败，这篇文章可以帮你解决。 常见的报错包括： Task ':app:createBundleReleaseJsAndAssets' property 'entryFile' specifies file 'index.js' which doesn't exist. 或者： java.lang.OutOfMemoryError: Metaspace Execution failed for task ':react-native-xxx:lintVitalAnalyzeRelease' 这通常是由于入口文件未正确配置，以及 Gradle 内存不足导致的。下面是完整修复步骤。 1. 修复入口文件路径错误 React Native 默认查找 index.js ，如果你使用 TypeScript，需要告诉 Gradle 使用 index.ts 。 打开 android/app/build.gradle ，在 react {} 配置中加入： react { entryFile = file("../../index.ts") } 同时确认 package.json 中的入口文件： "main": "index.ts" 并在 metro.config.js 中支持 TypeScript： resolver: { sourceExts: ["js", "json", "ts", "tsx"] } 2. 解决 Gradle Metaspace 内存不足 Android 在 Release 构建时会运行 Lint 分析 React Native 库的 Kotlin 文件，默认内存太小会导致崩溃。 编辑 an...

Fixing React Native Android Release Build Errors with TypeScript & Hermes If your React Native Android release build fails after renaming index.js to index.ts , you're not alone. This is one of the most common issues when modernizing a React Native project with TypeScript and Hermes. Here are the two major errors you’ll likely see: Task ':app:createBundleReleaseJsAndAssets' property 'entryFile' specifies file 'index.js' which doesn't exist. And later: java.lang.OutOfMemoryError: Metaspace Execution failed for task ':react-native-xxx:lintVitalAnalyzeRelease' Let’s fix both problems step by step. 1. React Native Can’t Find Your Entry File React Native expects your app’s entry file to be index.js . When you rename it to index.ts , Gradle doesn’t know where to look. Open android/app/build.gradle and add this inside the react {} block: react { entryFile = file("../../index.ts") } Also make sure your package...
