标签图标API 3级和大于之间的兼容性; = 5 [英] Tab icons compatibility between API level 3 and >=5

问题描述

我的应用程序使用标签和它是建立在SDK级别3（Android 1.5的）。

My application uses tabs and it is built on top of SDK Level 3 (Android 1.5).

谷歌提到，标签图标的Andr​​oid 2.0彻底改变，所以他们建议制作两套图标，一个为＆LT; 5级，另一个为> = 5级，并设置的android：targetSdkVersion 来在应用程序清单5（见的 http://developer.android.com/guide/practices/ui_guidelines/icon_design_tab.html ）。但这种属性在API级别4中引入的，所以没有办法来声明，因为我对API级别3（见的http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#target).

Google mentions that tab icons "changed drastically" in Android 2.0, so they recommend making two sets of icons, one for < level 5 and another for >= level 5, and set the android:targetSdkVersion to 5 in the application manifest (see http://developer.android.com/guide/practices/ui_guidelines/icon_design_tab.html). BUT this attribute was introduced in API Level 4, so there is no way to declare it because I'm on API Level 3 (see http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#target).

什么是处理这种情况的正确方法？

What's the proper way to handle this case?

推荐答案

开发code处第3级（保证不使用后来被引入的API）后，目标级别更改为5或更高，修补清单。 code编译近期目标将只要code只使用3级API调用上的3级设备上运行。您还可以使用-V5中的名称添加资源文件夹放平> = 5个图标。

After developing the code at level 3 (to guarantee that you aren't using APIs that were introduced later), change the target level to 5 or higher and patch up the manifest. Code compiled for more recent targets will run on level 3 devices as long as the code only uses level 3 API calls. You can also add resource folders with "-v5" in the name to put the level >= 5 icons.
