Question

3月，我可以使用命令ionic cordova build android将我的项目很好地构建为apk文件，但是大约4个月无所事事之后，它现在变得无法构建。

我已经研究并跟踪了一些内容，但没有任何效果，包括： Running "cordova build android" - unable to find attribute android:fontVariationSettings and android:ttcIndex

$ ionic -v 5.0.3

$ cordova -v 9.0.0（cordova-lib@9.0.1）

使用依赖项和插件： “ @ ionic-native / brightness”：“ ^ 4.15.0”， “ @ ionic-native / core”：“ ^ 4.12.2”， “ @ ionic-native / firebase”：“ ^ 4.12.0”， “ @ ionic-native / google-maps”：“ ^ 4.12.0”， “ @ ionic-native / in-app-browser”：“ ^ 4.12.0”， “ @ ionic-native / splash-screen”：“〜4.11.0”， “ @ ionic-native / status-bar”：“〜4.11.0”， “ @ ionic / storage”：“ 2.1.3”，

"cordova-android": "7.0.0",
"cordova-plugin-brightness": "^0.2.0",
"cordova-plugin-device": "^2.0.2",
"cordova-plugin-firebase": "^1.1.4",
"cordova-plugin-googlemaps": "^2.4.6",

Answer 1

尝试转到 platform / android 文件夹并编辑 project.properties 文件，并替换 com.android.support:support-v4：+ < / strong>和 com.android.support:support-v4:27.1.0 。

这只是解决该问题的一种快速方法，您必须查找使用哪个库引发此错误。

Answer 2

将compileSdkVersion更改为：

compileSdkVersion 28

fontVariationSettings和ttcIndex已在api 28级中添加。
