duplicate files copied in apk

既然是apk包内文件重复问题，首先查引入的包有没有重复，如果没有找到重复的地方，就用下面的方法进行规避。
exclude用于排除，pickFirst只用第一次出现的，忽略后面出现的。

android {packagingOptions {        exclude 'META-INF/DEPENDENCIES.txt'        exclude 'META-INF/LICENSE.txt'        exclude 'META-INF/NOTICE.txt'        exclude 'META-INF/NOTICE'        exclude 'META-INF/LICENSE'        exclude 'META-INF/DEPENDENCIES'        exclude 'META-INF/notice.txt'        exclude 'META-INF/license.txt'        exclude 'META-INF/dependencies.txt'        exclude 'META-INF/LGPL2.1'        pickFirst 'lib/x86/libRoadLineRebuildAPI.so'        pickFirst 'lib/armeabi/libRoadLineRebuildAPI.so'   }}
