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.gradleaaptOptions.cruncherEnabled = falseaaptOptions.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 30defaultConfig {applicationId "com.example.tianxi_user"minSdkVersion flutter.minSdkVersion //最低兼容的安卓版本，flutter中默认是16targetSdkVersion flutter.targetSdkVersion //应用适配的安卓版本 flutter中默认是33versionCode flutterVersionCode.toInteger()versionName flutterVersionNamendk {//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}"
}
