我正在使用onesignal进行Android通知，而someignal需要sdk v26，当我尝试编译v26.1时，会显示以下错误。
Environment第一个错误是：
Error:(140) Attribute "font" already defined with incompatible format.
Error:(128) Original attribute defined here.
Error:Execution failed for task ':app:processDebugResources'.> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'D:\android-sdk-windows\build-tools\26.0.1\aapt.exe'' finished with non-zero exit value 1
第二
<declare-styleable name="FontFamilyFont"><attr name="fontStyle"><enum name="normal" value="0"/><enum name="italic" value="1"/></attr><attr format="reference" name="font"/><attr format="integer" name="fontWeight"/></declare-styleable>
我的依赖项：
<declare-styleable name="CfViewsCustomAttributes"><attr format="integer" name="font"><enum name="normal" value="0"/></attr></declare-styleable>
