今天当我想从我的项目中获得一个版本时,android studio显示这个错误:
android {
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
}
所以我打开lint的报告文件夹,看到这个错误:
<issue
id="ResAuto"
severity="Fatal"
message="In Gradle projects, always use `http://schemas.android.com/apk/res-auto` for custom attributes"
category="Correctness"
priority="9"
summary="Hardcoded Package in Namespace"
explanation="In Gradle projects, the actual package used in the final APK can vary; for example,you can add a `.debug` package suffix in one version and not the other. Therefore, you should **not** hardcode the application package in the resource; instead, use the special namespace `http://schemas.android.com/apk/res-auto` which will cause the tools to figure out the right namespace for the resource regardless of the actual package used during the build."
errorLine1=" xmlns:app="http://schemas.android.com/apk/res/ir.app.appname">">"
errorLine2=" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
quickfix="studio">
<location
file="C:\...\app\src\main\res\color\mybutton_backgroundcolor.xml"
line="3"
column="16"/>
</issue>
mybutton_backgroundcolor.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res/ir.app.appname">
<item android:state_enabled="true" app:state_read ="false" android:color="@color/backgrpund_button_success"/>
<item android:state_enabled="false" app:state_read ="false" android:color="@color/gray_4"/>
<item app:state_read ="true" android:color="@color/gray_4"/>
</selector>
错误在此xmlns:app =“http://schemas.android.com/apk/res/ir.app.appname”>行中。
有人可以帮我解决这个问题吗?!
更新:将com.android.support
库更新到版本28后发生此错误
app
名称空间应声明为xmlns:app="http://schemas.android.com/apk/res-auto"
:
正如Lint所说:
在Gradle项目中,最终APK中使用的实际包可能会有所不同;因为你可以在一个版本中添加一个
.debug
包后缀而不是另一个版本。因此,您不应该在资源中硬编码应用程序包;相反,使用特殊的命名空间http://schemas.android.com/apk/res-auto
,这将使工具找出资源的正确命名空间,而不管构建期间使用的实际包。
