Question

我正在使用Ionic3：

global packages:

    @ionic/cli-utils : 1.3.0
    Cordova CLI      : 6.4.0 
    Ionic CLI        : 3.3.0

local packages:

    @ionic/app-scripts              : 1.3.0
    @ionic/cli-plugin-cordova       : 1.3.0
    @ionic/cli-plugin-ionic-angular : 1.3.0
    Cordova Platforms               : android 6.0.0 ios 4.3.1
    Ionic Framework                 : ionic-angular 3.2.1

System:

    Node       : v7.10.0
    OS         : macOS Sierra
    Xcode      : Xcode 8.3.2 Build version 8E2002 
    ios-deploy : not installed
    ios-sim    : not installed

然后我将Cordova升级到最新版本（从6.4.0升级到7.0.1）：

global packages:

    @ionic/cli-utils : 1.3.0
    Cordova CLI      : 7.0.1 
    Ionic CLI        : 3.3.0

local packages:

    @ionic/app-scripts              : 1.3.0
    @ionic/cli-plugin-cordova       : 1.3.0
    @ionic/cli-plugin-ionic-angular : 1.3.0
    Cordova Platforms               : android 6.2.3 ios 4.3.1
    Ionic Framework                 : ionic-angular 3.2.1

System:

    Node       : v7.10.0
    OS         : macOS Sierra
    Xcode      : Xcode 8.3.2 Build version 8E2002 
    ios-deploy : not installed
    ios-sim    : not installed

如您所见，我还将我的Android平台从android 6.0.0升级为android 6.2.3。

从那以后，我无法让我的Cordova插件在Android上运行。 iOS和浏览器一切正常。

如果我在Android设备或模拟器上运行它，它会加载应用程序，但不会显示启动画面，或者获取地理定位，允许Firebase登录等等。看起来所有适用于Android的Cordova插件都无法正常工作。

当我在Android Studio中运行时，我会在日志中反复获得以下内容：

W/art: Attempt to remove non-JNI local reference, dumping thread

似乎安装最新的Android平台（6.2.3）已经破坏了应用程序。

欢迎任何建议。

更新

现在我尝试卸载Android平台并重新安装6.0.0版。但我得到错误：

可是：

cordova platform ls
Installed platforms:
  android 6.0.0
  ios 4.3.1

然后

cordova build android
✖ Running command - failed!

[ERROR] Cordova encountered an error.
        You may get more insight by running the Cordova command above directly.

        Looked here: /Users/richardmarais/Library/Android/sdk/tools/templates/gradle/wrapper

我在Android Studio中检查了我的Android SDK，并且安装了所有最新版本（Android 6.0,7.0和7.1）。

所以我升级回最新的Android平台：

cordova platform remove android
ionic cordova platform add android@latest

现在它再次构建没有错误，但是我遇到了Cordova插件无法正常工作的问题，以及日志中的以下内容：

W/art: Attempt to remove non-JNI local reference, dumping thread

Answer 1

解决：

已删除node_modules

npm install

ionic cordova platform remove android
ionic cordova platform add android@latest

ionic cordova build android

升级Cordova导致Android平台停止工作
