uses-sdk:minSdkVersion 19 不能小于库中声明的版本 21

Question

我最近将 cordova-android 升级到版本 12，我的应用程序不再构建，并且出现以下错误

uses-sdk:minSdkVersion 19 不能小于库中声明的版本 21

我知道我需要将最低版本提高到 21 或更高版本，我已在 config.xml 文件中完成此操作：-

<platform name="android">
...
<preference name="android-minSdkVersion" value="24" />
...
</platform>

我已经多次删除和添加平台，但仍然出现构建失败并出现上述错误的情况。我谷歌搜索的所有内容都以相同的答案结束（更改 config.xml 文件中的 android-minSdkVersion 版本）。

我正在拔头发，因为我确信这是我明显遗漏的东西，感谢您的帮助，如果您需要更多信息（使用的插件等，请告诉我）。

Answer 1

您可能已在 gradle 构建配置中设置了最小 sdk 版本。请参阅 https://developer.android.com/build/gradle-tips#combine-multiple-product-flavors，其中显示在 gradle 文件中使用

minSdkVersion

。

Answer 2

只需在本地升级 Flutter 即可看到魔法发生。

flutter upgrade
