服务端 PHP后台管理

    项目需要一个头像上传的需求,unity只有调用相机接口不知道兼容性如何所以必须写系统原生比较安全,很多代码也是各种搬砖解决,只是为了记录下。

  流程

应用头像管理方案 android_第1张图片

 

Android项目

 

几个坑 下面代码已经都解决

1.miui系统 在图片裁切return-data 无法返回数据 

2.API >=24系统需要用 共享库来获取资源路径 Provider

authorities 值必须唯一 导致 同一签名文件,多包名APK 安装失败

解决办法 打包的时候动态修改这个值和包名匹配

Manifest.xml添加 文件库权限

添加Activcity

Unity调用接口启动Activity

	//Unity中会调用这个方法,用于区分打开摄像机 开始本地相册
	 public void TakePhoto(String str)
	 {
	         android.content.Intent intent = new android.content.Intent(this,WebViewActivity.class);
	         intent.putExtra("type", str);
	         this.startActivity(intent);
	 }	

下面代码是android activity 代码逻辑
