【问题描述】:

如果我在构建等级中设置了此符号,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}\"")

清单文件上有这个:

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

谢谢!

【解决方案1】:

进入build.gradle文件并粘贴到android中

aaptOptions {
        noCompress "webp"
    } 

然后将其粘贴到默认配置中

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}\"")
