android Native和 Flutter 通信

android 工程集成Flutter

集成方式主要是两种

1、 工程的方式集成

首先创建android，和flutter工程，工程路径必须在同一路径下：

1、在android 工程的settings.gradle 文件中添加：

rootProject.name = "flutterDemo"
include ':app'
// 添加如下代码
setBinding(new Binding([gradle: this]))
evaluate(new File(
  settingsDir,
  '../flutter_module/.android/include_flutter.groovy'
))

2、app的 build.gradle

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.3.1'
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.2.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.1'
    // 添加依赖
    implementation project(path: ':flutter')
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

3、 清单文件 ndroidManifest.xml 中添加
集成完，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.flutterdemo">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.FlutterDemo">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <!--    添加activity     -->
        <activity
            android:name="io.flutter.embedding.android.FlutterActivity"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:theme="@style/Theme.FlutterDemo"
            android:windowSoftInputMode="adjustResize" >
        </activity>

    </application>

</manifest>

4、 添加跳转测试：

package com.example.flutterdemo

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import io.flutter.embedding.android.FlutterActivity

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        findViewById<View>(R.id.btn).setOnClickListener {
            var intent =  FlutterActivity.createDefaultIntent(MainActivity@ this)
            startActivity(intent)
        }
    }
}

5、 集成完后效果：

2、 aar方式集成

1、使用命令build aar ： flutter build aar
