android - 添加 oneSignal 插件 cordova - Ionic 2

Question

我很好地将 onesignal-cordova-plugin 添加到我的项目中，但是当我想要构建 (ionic cordova run android) 时，我遇到了这个错误:

Observed package id 'build-tools;26.0.0-rc1' in inconsistent location 'E:\SDK\build-tools\26.0.0-preview' (Expected 'E:\SDK\build-tools\26.0.0-rc1')
Errors during XML parse:
White spaces are required between publicId and systemId.

javax.xml.bind.UnmarshalException
 - with linked exception:
[org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 62; White spaces are required between publicId and systemId.]
Additionally, the fallback loader failed to parse the XML.

Answer 1

终于找到解决办法了!首先最好看onesignal-plugin-versions ;

据此:

2.2.0 Release :

Dropped Android 2.3 (API 9) support, minimum is now 4.0.3 (API 15).

所以我们有两个选择:

1. 增加config.xml中的minSdkVersion

2. 降低onesignal-cordova-plugin版本(ionic cordova plugin add onesignal-cordova-plugin@2.1.2)
