flutter打包安卓apk常用配置

打包之前需要先不配置不然会报错 Execution failed for task ‘:app:mergeReleaseResources’.

APP目录下的build.gradle aaptOptions.cruncherEnabled = false aaptOptions.useNewCruncher = false

如图

配置targetSdkVersion 、minSdkVersion 在android/app/src目录下的build.gradle配置 在这两个地方配置就可以 比如安卓应用商店是安卓targetSdkVersion api 30 defaultConfig { applicationId "com.example.tianxi_user" minSdkVersion flutter.minSdkVersion //最低兼容的安卓版本，flutter中默认是16 targetSdkVersion flutter.targetSdkVersion //应用适配的安卓版本 flutter中默认是33 versionCode flutterVersionCode.toInteger() versionName flutterVersionName ndk { //设置支持的SO库架构（开发者可以根据需要，选择一个或多个平台的so） abiFilters "armeabi", "armeabi-v7a", "arm64-v8a", "x86","x86_64" // biFilters "armeabi", "armeabi-v7a", "arm64-v8a","x86","x86_64" } } 或者去flutter安装目录中去配置 一劳永逸 flutter\packages\flutter_tools\gradle flutter.gradle 修改这里的配置 class FlutterExtension { /** Sets the compileSdkVersion used by default in Flutter app projects. */ static int compileSdkVersion = 33 /** Sets the minSdkVersion used by default in Flutter app projects. */ static int minSdkVersion = 16 /** Sets the targetSdkVersion used by default in Flutter app projects. */ static int targetSdkVersion = 33 /** * Sets the ndkVersion used by default in Flutter app projects. * Chosen as default version of the AGP version below as found in * https://developer.android.com/studio/projects/install-ndk#default-ndk-per-agp */ static String ndkVersion = "23.1.7779620" /** * Specifies the relative directory to the Flutter project directory. * In an app project, this is ../.. since the app's build.gradle is under android/app. */ String source /** Allows to override the target file. Otherwise, the target is lib/main.dart. */ String target } 使用自定义证书签名打包 使用 keytool 生成签名证书,placement certificate keytool -genkey -v -keystore xxx(项目名).keystore -alias xxx(项目名) -keyalg RSA -keysize 2048 -validity 10000 -storepass （storePassword密码） -keypass （keyPassword密码） 根据提示生成证书keystore 将 text.keystore 文件放到 android/app/ 目录下。编辑 android/app/build.gradle,添加 signingConfigs: android { ... signingConfigs { release { keyAlias 'text' keyPassword '***' storeFile file('text.keystore ') storePassword '***' } } buildTypes { ... release { signingConfig signingConfigs.release } } }

填入 keystore 的密码。

最后使用 flutter build apk --release 进行签名打包。

只打包32/64

现在很多安卓应用商店只支持64位 安卓api30以上的。这里要调整下 只支持64位:flutter build apk --target-platform android-arm64

支持32位:flutter build apk --target-platform=android-arm 同时支持64位和32位:flutter build apk

报错Could not create task ':flutter_plugin_android_lifecycle:generateDebugUnitTestConfig 在Android Studio中 打开安卓目录 修改文件,把下面代码注释，在flutter中运行的时候放开 subprojects { // // 把这行注释掉，在flutter运行的时候，记得取消这行的注释 // project.buildDir = "${rootProject.buildDir}/${project.name}" }
