ionic2 打包時報錯 file-opener2

在app自動更新過程當中，有用到ionic-native插件：cordova-plugin-file-openner2    添加插件後，打包時有錯：

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'android'.
> Could not resolve all dependencies for configuration ':_debugCompile'.
> Could not find any version that matches com.android.support:support-v4:+.
Searched in the following locations:
https://repo1.maven.org/maven2/com/android/support/support-v4/maven-metadata.xml
https://repo1.maven.org/maven2/com/android/support/support-v4/
Required by:

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

經過一番查詢，多是插件版本問題；

在這兒發現瞭解決辦法-------->

好，因而就在 config.xml中作了以下更改：

改以前：

<plugin name="cordova-plugin-file-opener2" spec="~2.0.15" />

改以後（若是沒有就添加打包的時候 項目會自動添加）：

<plugin name="cordova-plugin-file-opener2" spec="1.0.11" />

好吧----這就能夠用了 打包成功！！

 總結：本身太菜！
