Android7.0自动更新适配包解析异常

2023-09-11 15:06:05 203

在Android7.0的手机上，自动更新的时候出现包解析异常，在其他的手机上没有这个问题。

原因：

Android7.0引入私有目录被限制访问和StrictModeAPI。私有目录被限制访问是指在Android7.0中为了提高应用的安全性，在7.0上应用私有目录将被限制访问。StrictModeAPI是指禁止向你的应用外公开file://URI。如果一项包含文件file://URI类型的Intent离开你的应用，则会报出异常。

解决办法：

第一步：在AndroidManifest.xml中注册provider，provider可以向应用外提供数据。


//在第二步的时候会有介绍

第二步：在res/xml中创建file_paths.xml文件。

第三步：贴出我的自动更新下载的代码
