Sometimes we want to add new resources in the standard Framework. What should we do?
The solution is to try it.
Through the Eclipse contact, we can think of whether it is simply to put the string in each folder of res. Let's try it out first, compile it, and the system reports an error immediately. Why?
It prompts you to use the make update-api command to update the public. xml file or call this Declaration the hide type. This is definitely not what we want.
So there are two methods:
Method 1:After adding resources, execute the make update-api function. The system updates the res/values/public. xml file.
Method 2:After adding resources, manually change the/res/values/public. xml file. Open the public. xml file. The found structure is as follows:
Copy codeThe Code is as follows: <resources>
<! -- We don't want to publish private symbols in Android. R as part of
SDK. Instead, put them here. -->
<Private-symbols package = "com. android. internal"/>
<! -- AndroidManifest. xml attributes. -->

<Public type = "attr" name = "author" id = "0x010102b4"/>
<Public type = "attr" name = "autoStart" id = "0x010102b5"/>
</Resources>
In this way, we can add them by ourselves.
Recommended method 1 is also the most standard practice. Why?
1: Avoid duplicate IDs.
2: Trouble
3: standardized practices.
