cocosCreator

CocosCreator打包原生Android项目接入微信登陆

前往 微信官方文档 •开放平台 ，Android开发工具包下载，范例代码HelloWeixin下载。

一、生成安卓keystore签名

使用这个Android Studio 生成的keystore，有一个在线生成安卓证书在线制作工具

二、在所在包名下的目录新建一个文件夹wxapi

然后新建一个类 WXEntryActivity.java名字和文件名需要一样。

三、实现WXEntryActivity.java代码

<activity

    android:label="@string/app_name"
    android:theme="@android:style/Theme.Translucent.NoTitleBar"
    android:taskAffinity="com.ds.～"//这儿换成你自己的
    android:exported="true"
    android:launchMode="singleTask">
</activity>

添加位置，如图红色框的部分:

其中android:name = "com.~.wxapi.WXEntryActivity"这个就是对应这个路径目录。

添加WXAPI依赖，打开build.gradle文件,注意是proj.android-studio/～你的项目名字 目录下,在dependencies中加下面的代码 api 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+'，这儿game下的 build.gradle也要添加。

    implementation fileTree(dir: "/Applications/CocosCreator2.3.2.app/Contents/Resources/cocos2d-x/cocos/platform/android/java/libs", include: ['*.jar'])
    implementation project(':libcocos2dx')
    api 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+' 
}

AppActivity.java中的实现，wxLogin函数必须是静态的,这样才可以去外部调用。

这儿微信登陆需要真机调试，为了方便直接打包debug和release使用之前生成keystore。

上面的密码改成生成 keystore时的密码，然后再调试运行在手机上。

这儿如果有什么问题可以直接企鹅上留言: 1197696574 交流。
