android集成咸鱼的FlutterBoost

早就看到咸鱼发布的flutterboost的文章,能够在连续的flutter页面公用一个引擎达到节省内存和统一管理路由这些有点.但一直没有时间去试用它,趁着这两天app发版做了一下尝试.在接入过程中折腾了小半天,理解后觉得并没有想象中的那么复杂,所以写下来给后来者,节省不必要的时间.
下面开始说说的接入之旅
1.在原有项目执行flutter命令新建一个modue

flutter create -t module test_flutter

此时会生成一个flutter module

2.在app项目的根目录下的setting.gradle中加入以下代码

setBinding(new Binding([gradle: this]))
evaluate(new File(
  settingsDir.parentFile,
  '你的工程目录/test_flutter/.android/include_flutter.groovy'   // 比如我的原有工程明叫MixFlutterTest 刚才创建的flutter module叫test_flutter 那么这个地方应该是MixFlutterTest/test_flutter/.android/include_flutter.groovy
)) 

3.在原有项目的app目录下的build.gradle中增加对flutter的依赖 'app/build.gradle'

dependencies {
  implementation project(':flutter')
}

4.在第一步中新增的flutter module下的pubspec.yaml中新增对咸鱼flutter插件的依赖 'test_flutter/pubspec.yaml'

name: test_boost
description: A new flutter module project.
version: 1.0.0+1

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  xservice_kit: ^0.0.18
  flutter:
    sdk: flutter
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_boost:
    path: ../../../flutter_boost-master

flutter:
  uses-material-design: true
  module:
    androidPackage: com.example.test_boost
    iosBundleIdentifier: com.example.testBoost

注意

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_boost:
    path: ../../../flutter_boost-master // 这个地方是从github下载下来的本地flutter_boost的项目地址 并且从此flutter module目录开始去找flutter_boost-master的地址 ..是上一层目录 你需要根据你的flutter_boost-master地址来定义这个路径

test_flutter/pubspec.yaml中新增了两个地方

dependencies:
  xservice_kit: ^0.0.18

flutter_boost:
    path: ../../../flutter_boost-master

注意看上面的pubspec.yaml文件配置

5.在app工程中引入flutter_boost依赖代码 在第三部的地方 'app/build.gradle'

dependencies {
  implementation project(':flutter')
  implementation project(':flutter_boost')  // 新增
}

在build工程时会报错,需要在工程中加入

android {
    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }
}

完整的build文件 app/build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "cn.mf.mixfluttertest"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation project(':flutter')
    implementation project(':flutter_boost')
}

接入完成后 build后工程目录是这样

注意标注 1 和 2的地方
build工程时可能还会报错你需要修改下1和2的build.gradle配置 改成和你相对应的build版本,里面的配置项尽可能的和app/build.gradle里的编译选项保持一致

标注1的地方

group 'com.taobao.idlefish.flutterboost'
version '1.0-SNAPSHOT'

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2' // 注意
    }
}

rootProject.allprojects {
    repositories {
        google()
        jcenter()
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 27 // 注意
    buildToolsVersion "27.0.3" // 注意 编译版本
    defaultConfig {
        minSdkVersion 16 // 注意 最小sdk版本
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    lintOptions {
        disable 'InvalidPackage'
    }
}

dependencies {
    implementation 'com.alibaba:fastjson:1.2.41' // 注意
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.android.support:appcompat-v7:27.1.1'
    compileOnly rootProject.findProject(":xservice_kit") // 注意可能提示换成compileOnly 按照提示换成compileOnly就行
}

ext {
    groupId = 'com.taobao.fleamarket'
    artifactId = "FlutterBoost"
}

标注2的地方

group 'com.taobao.idlefish.xservice_kit'

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

rootProject.allprojects {
    repositories {
        google()
        jcenter()
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 27 // 注意
    buildToolsVersion "27.0.3" // 注意
    defaultConfig {
        minSdkVersion 16 // 注意
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    lintOptions {
        disable 'InvalidPackage'
    }
}

6.最后可能还会提示app里的 android:allowBackup="true" 不允许
找到标注1中 src/main/java/AndroidManifest.xml 把android:allowBackup="true"改为android:allowBackup="false"
编译时可能还会提示BoostFlutterNativeView中36有错误

com/taobao/idlefish/flutterboost/BoostFlutterNativeView.java:36: 错误: 方法不会覆盖或实现超类型的方法
@override

找到这个文件 删除调这个方法就行 变成这样

import android.content.Context;

import io.flutter.view.FlutterNativeView;

public class BoostFlutterNativeView extends FlutterNativeView {

    public BoostFlutterNativeView(Context context) {
        super(context);
    }

    @Override
    public void destroy() {
        //do nothing...
    }

    public void boostDestroy() {
        super.destroy();
    }
}

ok所有步骤都完成了 祝你好运
