1.安装时提示“应用组件的命名与已安装应用有冲突”
出现这个问题是用于同一套代码打了两个applicationId的包，而手机上已经安装了其中一个，安装另外一个时就会报错。其原因是Manifast中配置的ContentProvider中的authorities没有更改，致使两个不同applicationId的authorities相同
2.Error while generating the main dex list
打包时报了这个错，详细报错情况如下：
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:transformClassesWithMultidexlistForRelease'.
> com.android.build.api.transform.TransformException: Error while generating the main dex list.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Get more help at https://help.gradle.org
具体是哪个包冲突了可以再RunTask中找到
3.More than one file was found with OS independent path
在出错的Model的gradle的android节点下添加
packagingOptions {
pickFirst 'META-INF/*'
}
