从flutter v1.17版本开始flutter module仅支持AndroidX的应用在release模式下flutter仅支持一下架构x84_64、armeabi-v7a、arm6f4-v8a,不支持mips和x86;所以引入flutter前需要在app/build.gradle下配置flutter支持的架构
android {defaultConfig {ndk {// armeabi已经淘汰0%// armeabi-v7a曾经主流的架构平台20%// arm64-v8a目前主流架构平台80%abiFilters armeabi-v7a, arm64-v8a}}
}
1、源代码集成
将flutter集成到现有的Android应用中主要步骤如下
创建flutter module为已存在的Android应用添加flutter module依赖(setting.gradle中加入代码)在需要的module引入添加Java 8编译选项在kotlin中调用flutter module编写dart代码
创建flutter module //--org后面为域名 flutter_module为module名称 flutter create -t module --org com.example.module flutter_module 生成module的目录结构 为已存在的Android应用添加flutter module依赖
打开Android项目的setting.gradle添加如下代码
setBinding(new Binding([gradle: this]))
evaluate(new File(settingsDir.parentFile,flutter_module/.android/include_flutter.groovy
))//可选作用可以在当前AS的project下显示flutter_module以方便查看和编写Dart代码
include :flutter_module
project(:flutter_module).projectDir new File(../flutter_module)
在需要的module引入 //asproj/app/build.gradle
implementation project(:flutter) 添加Java 8编译选项 因为flutter的Android engine是用来Java8的特性所以在引入flutter时需要配置你的项目都Java8编译选项app/build.gradle android {compileOptions {sourceCompatibility 1.8targetCompatibility 1.8}
} 在kotlin中调用flutter module抽取一个基类HiFlutterFragment如下代码 package org.devio.as.proj.common.flutterimport android.content.Context
import android.os.Bundle
import android.view.View
import android.view.ViewGroup
import io.flutter.embedding.android.FlutterTextureView
import io.flutter.embedding.android.FlutterView
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.embedding.engine.dart.DartExecutor
import kotlinx.android.synthetic.main.fragment_flutter.title
import org.devio.as.proj.common.R
import org.devio.as.proj.common.ui.component.HiBaseFragmentabstract class HiFlutterFragment : HiBaseFragment() {private lateinit var flutterEngine: FlutterEngineprotected var flutterView: FlutterView? nulloverride fun onAttach(context: Context) {super.onAttach(context)flutterEngine FlutterEngine(context)flutterEngine.dartExecutor.executeDartEntrypoint(DartExecutor.DartEntrypoint.createDefault())}override fun getLayoutId(): Int {return R.layout.fragment_flutter}fun setTitle(titleStr: String) {title.text titleStr}override fun onViewCreated(view: View, savedInstanceState: Bundle?) {super.onViewCreated(view, savedInstanceState)(layoutView as ViewGroup).addView(createFlutterView(activity!!))}override fun onStart() {flutterView!!.attachToFlutterEngine(flutterEngine!!)super.onStart()}override fun onResume() {super.onResume()//for flutter v1.17flutterEngine.lifecycleChannel.appIsResumed()}override fun onPause() {super.onPause()flutterEngine.lifecycleChannel.appIsInactive()}override fun onStop() {super.onStop()flutterEngine.lifecycleChannel.appIsPaused()}override fun onDetach() {super.onDetach()flutterEngine.lifecycleChannel.appIsDetached()}private fun createFlutterView(context: Context): FlutterView {//使用FlutterTextureView来进行渲染以规避fluttersurfaceview压后台回来后界面被复用的问题val flutterTextureView FlutterTextureView(activity!!)flutterView FlutterView(context, flutterTextureView)return flutterView!!}} 调试dart代码 1.关闭app(这一步很关键) 2.attach到Android项目中 使用命令行然后切换到flutter_module目录下运行flutter attach当有多个设备时用如flutter attach -d emulator-5554不使用命令行 3.启动app 2、maven仓库集成方式详细步骤耐心等待 这种集成方式不需要所有团队成员都安装flutter 环境。只需要 flutter 开发者在开发完功能模块。通知 Native 开发着更新一下依赖。就可以完成功能的更新。这样的话Native 开发者并不会有 flutter 的代码并不知道具体实现方式。 将flutter集成到现有的Android应用中主要步骤如下 创建flutter module执行 flutter build aar 参考官方文档 https://flutter.dev/docs/development/add-to-app
