mergeDebugResources-17:/values/values.xml:3874: error: style attribute 'android:attr/customOperation1' not found.
error: failed linking references.

I met above compile error while compile my demo apk when I want to use the attrs added by myself in /frameworks/base/core/res/res/values/attrs.xml and public.xml .
In framework I add atts customOperation1 and framework compile OK, and then I configured dependence of classes.jar in Android Studio gradle file . But when I uses the attrs customOperation1 in my demo apk's theme , there's above error.

Something more : I added some interfaces in framework and configured classes.jar in my demo apk project ,and it can compile well. And also no problem at runtime when I called the interfaces added in framework.

So why the added attrs can not work ? Anyone any suggestions ?

Below is the code in my demo app theme try to use added attrs:
<item name="android:customOperation1">@drawable/decor_maximize_button_light</item>

Hi @e-Mood,

Is this a question specific to the permission handler? From the information you provided it seems to me that you require help directed at Android and its build process.

No worries. You can find help at several places online. For example the Android Stack Exchange: https://android.stackexchange.com/ and StackOverflow: https://stackoverflow.com/.

Having a quick glance at your question, the problem might be coming from the way you access your custom attr. If my memory serves me well, android:attr retrieves attributes bundled with the Android SDK. To access your attr you should leave out android. Your line of code would then become attr/customOperation1. I don't think you should be editing /frameworks/base/core/res/res/values/attrs.xml as this is part of the Android SDK. Instead, create your own attrs.xml file in the values directory in your project.

@JeroenWeener Thanks for your suggestion, I'm a framework developer and want to add our custom attrs in framework ,so our APP developers can use them in their app project . Then framework can implement specific features.
