推薦答案
如何更新庫中的 JAR?
How do I update the JARs in libs?
我通常通過復制文件來做到這一點.您將在 $ANDROID_SDK/extras/android/support 中找到 JAR，其中 $ANDROID_SDK 是安裝 Android SDK 的位置.
I usually do it by copying the file. You will find the JARs inside $ANDROID_SDK/extras/android/support, where $ANDROID_SDK is wherever your Android SDK is installed.
如果您使用 Eclipse，如果您在文件系統(tǒng)級別復制此文件，并且 Eclipse 已打開，請按 <F5> 并在包管理器中突出顯示項目，以便 Eclipse 獲取更改.更簡單的方法是將它拖出 SDK 并將 JAR 放入 Eclipse 中的 libs/ 中，這將更新文件系統(tǒng)并讓 Eclipse 知道更改.
If you use Eclipse, if you copy this at the filesystem level, and Eclipse is open, press <F5> with the project highlighted in Package Manager so Eclipse picks up the changes. Easier is to drag it out of the SDK and drop the JAR into libs/ right in Eclipse, which will both update the filesystem and let Eclipse know about the change.
添加 JAR 的 Eclipse 選項(右鍵單擊項目，然后從上下文菜單中選擇 Android Tools > Add Support Library...)也可能會執(zhí)行此操作.由于我的開發(fā)環(huán)境的一些特殊性，這種特殊方法對我不起作用.
It's possible that the Eclipse option to add the JARs (right-click over the project, then choose Android Tools > Add Support Library... from the context menu) will also do this. That particular approach doesn't work for me due to some peculiarities with my development environment.
