打包apk文件时，资源文件冲突。

解决H1

MavenH2

bash
<plugin>
    <groupId>com.jayway.maven.plugins.android.generation2</groupId>
    <artifactId>android-maven-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
        <extractDuplicates>true</extractDuplicates>
    </configuration>
</plugin>

GradleH2

bash
packagingOptions {
    exclude 'META-INF/notice.txt'
}

总结H1

Android官方文档对构建过程中打包apk的描述

All non-compiled resources (such as images), compiled resources, and the .dex files are sent to the apkbuilder tool to be packaged into an .apk file.

打包apk的过程中构建工具会把所有资源文件拷贝到apk文件中，文件冲突即会报错
