android 开发More than one file was found with OS independent path 'META-INF/DEPENDENCIES'

程序在运行到手机时，提示错误：More than one file was found with OS independent path 'META-INF/DEPENDENCIES'。

解决方法：

在app的build.gradle中添加如下代码：

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
}
