前言
公司要用到百度地图sdk的专业导航，让写个flutter插件。。。。
我负责android原生导航😁
在此记录
提示：以下是本篇文章正文内容，下面案例可供参考
一、准备
官方文档
https://lbsyun.baidu.com/index.php?title=android-navsdk/guide/projectConfiguration
根据文档配置权限，配置ak
二、下载demo
点击相关下载
把下面这两个都下载下来
解压
三、配置
将上面libs的复制到下面的目录（我有x86和x86_64因为之前同事写了地图插件🐓）
导入这两个aar
导入过程
然后finish
1.配置build.gradle（两个不同的）
代码如下（示例）：
android {compileSdkVersion 29defaultConfig {minSdkVersion 16}lintOptions {disable 'InvalidPackage'}sourceSets {main {//我加入的-------jniLibs.srcDir 'libs'//------------}}
}dependencies {implementation files('libs/BaiduLBS_Android.jar')implementation files('libs/okio-1.13.0.jar')implementation files('libs/okhttp-3.8.1.jar')implementation files('libs/bos-android-sdk-1.0.3.jar')implementation files('libs/BaiduTraceSDK_v3_1_7.jar')implementation files('libs/intellij_annotations.jar')implementation files('libs/javapoet-1.9.0.jar')implementation files('libs/protobuf-java-2.3.0-micro.jar')implementation files('libs/protobuf_gens-map.jar')implementation project(':onsdk_all')//我加入的-------implementation 'com.android.support:appcompat-v7:28.0.0'implementation 'com.android.support:cardview-v7:28.0.0'implementation 'com.android.support:recyclerview-v7:28.0.0'implementation 'com.android.support.constraint:constraint-layout:1.1.3'//----------implementation project(':NaviTts')
}
android {compileSdkVersion 29lintOptions {disable 'InvalidPackage'}defaultConfig {// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).applicationId "com.dyys.baidumap.plugin.flutter_baidumap_plugin_example"minSdkVersion 18targetSdkVersion 29versionCode flutterVersionCode.toInteger()versionName flutterVersionName//我加入的----------------// 避免"64K 引用限制"multiDexEnabled true// 导航SDK内部使用了annotationProcessor，需要添加下面代码，防止编译异常javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true }}//-----------------------------}buildTypes {release {// TODO: Add your own signing config for the release build.// Signing with the debug keys for now, so `flutter run --release` works.signingConfig signingConfigs.debug}}
2.打开apk试玩
看源码找到需要的demo界面（我：专业导航）（已改好）

获取TTS服务 appid等
打开网址
https://ai.baidu.com/
进入控制台
点击语音技术
创建应用
应用名称、应用描述随便填，包名填上面gradle中的 applicationId
创建完毕后如下，复制后填入即可
效果
使用模拟机会闪退，因为没有模拟机对应的资源（我的模拟机是X86的）😭
