在库清单中使用$ {applicationId}

Question

我正在开发一个使用内部ContentProvider的SDK,我想在一些项目中使用这个SDK,并在库清单中声明它,所以我试过这个:

    <provider
        android:name=".core.MyContentProvider"
        android:authorities="${applicationId}"
        android:exported="false"/>

会发生什么是$ {applicationId}被库的packageName替换而不是顶部的apk相关的applicationId ...

有没有办法确保启动 applicationId将被放置在android:authority值？

遇到了几个不同变体和唯一ID的相同问题,最后在Gradle构建应用程序时替换占位符键,有点像这样:

Gradle 3+

android.applicationVariants.all { variant ->
    variant.outputs.each { output ->
        output.processManifest.doLast {
            File manifestFile = file("$manifestOutputDirectory/AndroidManifest.xml")

            replaceInFile(manifestFile, 'P_AUTHORITY', variant.applicationId)
        }
    }
}

def replaceInFile(file, fromString, toString) {
    def updatedContent = file.getText('UTF-8')
            .replaceAll(fromString, toString)

    file.write(updatedContent, 'UTF-8')
}

Gradle <3

android.applicationVariants.all { variant ->
    variant.outputs.each { output ->
        output.processManifest.doLast{
            replaceInManifest(output, 'P_AUTHORITY', variant.applicationId)
        }
    }   
}

def replaceInManifest(output, fromString, toString) {
    def manifestOutFile = output.processManifest.manifestOutputFile
    def updatedContent = manifestOutFile.getText('UTF-8').replaceAll(fromString, toString)
    manifestOutFile.write(updatedContent, 'UTF-8')
}

然后在清单中:

<provider
    android:name=".core.MyContentProvider"
    android:authorities="P_AUTHORITY"
    android:exported="false"/>

这很方便了

您可以在清单文件下使用 ${applicationId}。只需确保在该库的 gradle 文件中没有“ applicationId ”。如果您在“ defaultConfig ”下的gradle文件中声明了它，请将其删除。

//So your gradle file of library(SDK) module looks like..

defaultConfig {
minSdkVersion Version.minSdk
targetSdkVersion Version.targetSdk
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
} 


//And your application gradle file looks like..

defaultConfig {
    applicationId "com.example.android"
    minSdkVersion Version.minSdk
    targetSdkVersion Version.targetSdk
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
 }
