AndroidStudio导入support-v13

事情是这样的，学艺不精，导致 用上了AS，连什么是library dependency，module dependency 还有那个file dependency

-----------------------------------正文割-----------------------------------------------

想要导入v13包。这种和普通的什么chat那种不一样，不是add as library

而是 file--> project structure -> 选择左侧边栏的module下的APP --> 选择右上方dependencies模块 --> 点击右上角的小+  -->  选择 library dependenciy

下面出来一堆选项，选择即可

---------------下面是错误方法！！--------------------

如果！是add as library这样的！

运行起来就会爆出如下错误

Error:Error converting bytecode to dex:
Cause: com.android.dex.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

:app:transformClassesWithDexForDebug FAILED

多亏了学长，还有自己虽然大三仍然能舔着个大脸去问。。
