android studio 问题总结

1.Error:duplicate files during packaging of APK /Users/mingwu/Development/Android/51offer1/app/build/outputs/apk/app-debug-unaligned.apk

Path in archive: META-INF/LICENSE

Origin 1: /Users/mingwu/Development/Android/51offer1/app/libs/jackson-annotations-2.5.0.jar

Origin 2: /Users/mingwu/Development/Android/51offer1/app/libs/jackson-databind-2.5.0.jar

You can ignore those files in your build.gradle:

android {

 packagingOptions {

   exclude 'META-INF/LICENSE'

 }

}

------导入Eclipse项目出错，原因存在重复jar文件，可是没有。上面红色的文字为提示在builde.gradle中添加信息

解决：app-->buidle.gradle文件内加

android {      

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

exclude 'META-INF/LICENSE'      

}      

}      

----->解决问题。
