Installation failed with message INSTALL_FAILED_CONFLICTING_PROVIDER.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?

原因：含有同名的provide,我发现在清单文件中有个我自己集成的百度更新的sdk的provide中的authorities参数 ,在两个项目中我直接拷贝过来的，导致没改名字。每个项目中的provide里面的authorities需要保证不同名称，改下重新编译可。authorities=”com.iflytek.enterprise.fileprovider”
