Answer 1

我不得不做以上两个答案的内容:

在platforms/android/phonegap-plugin-barcodescanner中:

搜索compile 'com.android.support:support-v4:+并替换compile 'com.android.support:support-v4:27+'.

在平台/ android:

搜索cordova.system.library.2=com.android.support:support-v4:+并替换cordova.system.library.2=com.android.support:support-v4:27.1.0.

希望能帮助到你.
