Cordova8不兼容旧版插件解决方案——以百度地图定位Cord

    注意:

    本文档中描述的修改插件的部分(步骤8~11)并非最佳方法,请直接使用以下git库安装!!!

    cordova plugin add https://github.com/gisxiaowei/cordova-plugin-baidumaplocation --variable ANDROID_KEY="<API_KEY_ANDROID>" --variable IOS_KEY="<API_KEY_IOS>"
    # 此处的API_KEY_XX来自于第一步,直接替换<API_KEY_XX>,也可以最后跟 --save 参数,将插件信息保存到config.xml中
    # 如果只需要Android端或者IOS端,可以只填写一个相应的AK,但是都不填肯定不行
    

    描述

    Cordova目前版本已到8.0.0,但由于Cordova7之后,对目录结构做了调整,导致之前不少插件无法加载。出现的常见问题如下:
    1、配置文件找不到

    Parsing platforms\android\res\xml\config.xml failed(node:10988) UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory
    

    2、带有libs包的Java程序编译不通过

    :app:compileDebugJavaWithJavacE:\mapp\qyjg\cordova\platforms\android\app\src\main\java\com\aruistar\cordova\baidumap\BaiduMapLocation.java:8:: com.baidu.location FAILED
    import com.baidu.location.BDLocation;
                             ^
    

    本人通过不停的google、百度,经实践总结出如下方案。本文以百度地图定位Cordova插件v3.0.2为例,说明如何使其适用于Cordova8。

    环境

    node v8.11.1
    npm 5.6.0
    cordova 8.0.0
    

    插件

    百度地图定位Cordova插件cordova-plugin-baidumaplocation

    步骤

    (1)安装cordova

    安装最新版本(这里有个坑,不要用cnpm安装,因为创建项目时会报缺少package.json的错误)

    npm install -g cordova
    

    安装某一版本

    npm install -g cordova@8.0
    

    卸载

    npm uninstall -g cordova
    

    (2)创建项目

    cd /d E:\mapp\demo 
    cordova create cordova com.my.demo 示例
    

    解释一下,第1行为进入某个目录下,第2行为在该目录下创建cordova文件夹,id为com.my.demo,名称为示例

    (3)添加Android平台

    安装cordova-android@7.0.0

    cd cordova
    cordova platform add android
    

    (4)apk签名

    ① 将C:\Program Files\Java\jdk1.8.0_172\bin将入环境变量的Path中;
    ② 生成秘钥release-key.keystore

    keytool -genkey -v -keystore C:\release-key.keystore -alias demo -keyalg RSA -keysize 2048 -validity 20000
    

    秘钥库密码和秘钥密码都可以设为demo..,其他信息可选。
    ③ 在cordova文件夹根目录放置release-key.keystorebuild.json
    build.json文件内容:

    {
        "android": {
            "debug": {
                "keystore": "release-key.keystore",
                "storePassword": "demo..",
                "alias": "demo",
                "password" : "demo..",
                "keystoreType": ""
            },
            "release": {
                "keystore": "release-key.keystore",
                "storePassword": "demo..",
                "alias": "demo",
                "password" : "demo..",
                "keystoreType": ""
            }
        }
    }
    

    ④ 获取SHA1
    通过如下命令得到SHA1

    keytool -v -list -keystore c:/release-key.keystore
    

    (5)申请百度地图Android Key

    访问http://lbsyun.baidu.com/apiconsole/key,创建应用,输入如下信息。
    应用名称:测试
    应用类型:Android SDK
    发布版SHA1:apk签名中得到的SHA1;
    包名:com.my.demo
    最终得到访问应用的AK。

    (6)安装百度地图定位Cordova插件

    将申请到的AK填入<API_KEY_ANDROID>位置后执行

    cordova plugin add cordova-plugin-baidumaplocation --variable ANDROID_KEY="<API_KEY_ANDROID>" --variable IOS_KEY="<API_KEY_IOS>"
    

    (7)定位代码

    // 进行定位
    baidumap_location.getCurrentPosition(function (result) {
        alert(JSON.stringify(result, null, 4));
    }, function (error) {
    
    });
    

    (8)运行cordova,报config.xml文件找不到

    运行:

    cordova run android
    

    报config.xml文件找不到:

    Parsing platforms\android\res\xml\config.xml failed(node:10988) UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory
    

    原因分析:

    cordova\platforms\android下多了libs文件夹,导致判断为Eclipse还是AndroidStudio出错。具体代码位于cordova\platforms\android\cordova\lib\AndroidStudio.jsvar eclipseFiles = ['AndroidManifest.xml', 'libs', 'res'];

    解决方法:

    在根目录下的config.xml文件中<platform name="android">标签后添加hook

    <platform name="android">
        <hook src="scripts/patch-android-studio-check.js" type="before_plugin_add" />
        <hook src="scripts/patch-android-studio-check.js" type="before_plugin_install" />
        <hook src="scripts/patch-android-studio-check.js" type="before_plugin_rm" />
        <hook src="scripts/patch-android-studio-check.js" type="before_plugin_uninstall" />
        <hook src="scripts/patch-android-studio-check.js" type="before_prepare" />
    </platform>
    

    scripts/patch-android-studio-check.js内容如下:

    /**
     * This hook overrides a function check at runtime. Currently, cordova-android 7+ incorrectly detects that we are using
     * an eclipse style project. This causes a lot of plugins to fail at install time due to paths actually being setup
     * for an Android Studio project. Some plugins choose to install things into 'platforms/android/libs' which makes
     * this original function assume it is an ecplise project.
     */
    module.exports = function(context) {
      if (context.opts.cordova.platforms.indexOf('android') < 0) {
        return;
      }
    
      const path = context.requireCordovaModule('path');
      const androidStudioPath = path.join(context.opts.projectRoot, 'platforms/android/cordova/lib/AndroidStudio');
      const androidStudio = context.requireCordovaModule(androidStudioPath);
      androidStudio.isAndroidStudioProject = function() {  return true; };
    };
    

    (9)再次运行cordova,Java代码编译出错

    出错信息:

    :app:compileDebugJavaWithJavacE:\mapp\qyjg\cordova\platforms\android\app\src\main\java\com\aruistar\cordova\baidumap\BaiduMapLocation.java:8:: com.baidu.location FAILED
    import com.baidu.location.BDLocation;
                             ^
    E:\mapp\qyjg\cordova\platforms\android\app\src\main\java\com\aruistar\cordova\baidumap\BaiduMapLocation.java:9:: com.baidu.location
    import com.baidu.location.BDLocationListener;
    

    原因分析:

    libs路径不正确

    解决方法:

    修改plugins\cordova-plugin-baidumaplocation\plugin.xml
    修改前

        <platform name="android">
            <source-file src="src/android/BaiduMapLocation.java" target-dir="src/com/aruistar/cordova/baidumap"/>
            <source-file src="libs/android/armeabi/liblocSDK7a.so" target-dir="libs/armeabi"/>
            <source-file src="libs/android/armeabi-v7a/liblocSDK7a.so" target-dir="libs/armeabi-v7a"/>
            <source-file src="libs/android/arm64-v8a/liblocSDK7a.so" target-dir="libs/arm64-v8a"/>
            <source-file src="libs/android/x86/liblocSDK7a.so" target-dir="libs/x86"/>
            <source-file src="libs/android/x86_64/liblocSDK7a.so" target-dir="libs/x86_64"/>
            <source-file src="libs/android/BaiduLBS_Android.jar" target-dir="libs"/>
        </platform>
    

    修改后

        <platform name="android">
            <source-file src="src/android/BaiduMapLocation.java" target-dir="src/com/aruistar/cordova/baidumap"/>
            <lib-file src="libs/android/armeabi" arch="device"/>
            <lib-file src="libs/android/armeabi-v7a" arch="device"/>
            <lib-file src="libs/android/arm64-v8a" arch="device"/>
            <lib-file src="libs/android/x86" arch="device"/>
            <lib-file src="libs/android/x86_64" arch="device"/>
            <lib-file src="libs/android/BaiduLBS_Android.jar" arch="device"/>
        </platform>
    

    (10)再次运行cordova,Java代码编译仍然出错

    原因分析:

    添加插件时,已生成相关代码,见platforms\android\app\src\main\java\com\aruistar\cordova\baidumap\BaiduMapLocation.java路径

    解决方法:

    移除Android,再添加

    cordova platform remove android
    cordova platform add android
    

    再次运行

    再次运行,成功执行。

    (11)执行定位代码时,定位出错

    输出IocType162IocTypeDescriptionNetWork location failed because baidu location service can not decrypt the request query, please check the so file!

    原因分析:

    查找百度地图相关开发文档,发现platforms\android\app\build.gradle文件中缺少sourceSets的配置,位于dependencies之上

        sourceSets{
            main {
                jniLibs.srcDir 'libs'
                jni.srcDirs = [] //disable automatic ndk-build
            }
        }
    }
    
    /*
     * WARNING: Cordova Lib and platform scripts do management inside of this code here,
     * if you are adding the dependencies manually, do so outside the comments, otherwise
     * the Cordova tools will overwrite them
     */
    
    
    
    dependencies {
    

    结语

    再次运行,成功输出当前地理位置信息,至此,终于完成Cordova8兼容旧版百度地图定位Cordova插件的功能。
