It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

楼主，项目换了个包名，然后重新打包安装的时候，会出现这个问题，怎么解决？

@enjoy-life-5 项目换了包名名要把applicationId 也一起换了（或者你卸载老包也可以老）；一台手机的两个App 不可以有个相同的fileprovider存在

    <provider

        android:exported="false"
