为什么我得到无法解析符号“CONTENT_PROVIDER_AUTHORITY”？

Question

如果我在构建等级上设置了此符号，为什么会出现“无法解析符号“CONTENT_PROVIDER_AUTHORITY”：

def contentProviderAuthority = applicationId + ".provider.StickerContentProvider"
        manifestPlaceholders =
                [contentProviderAuthority: contentProviderAuthority]
        // Adds a new field for the authority to the BuildConfig class.
        buildConfigField("String", "CONTENT_PROVIDER_AUTHORITY", "\"${contentProviderAuthority}\"")

这在清单文件中：

<provider
            android:name=".provider.StickerContentProvider"
            android:authorities="${contentProviderAuthority}"
            android:enabled="true"
            android:exported="true"
            android:readPermission="com.whatsapp.sticker.READ" />

谢谢！ <3

Answer 1

进入build.gradle文件并粘贴到android中

aaptOptions {
        noCompress "webp"
    } 

然后将其粘贴到 defaultconfig 中

def contentProviderAuthority = applicationId + ".StickerContentProvider"
        // Creates a placeholder property to use in the manifest.
        manifestPlaceholders =
                [contentProviderAuthority: contentProviderAuthority]
        // Adds a new field for the authority to the BuildConfig class.
        buildConfigField("String",
                "CONTENT_PROVIDER_AUTHORITY",
                "\"${contentProviderAuthority}\"")
