升级Cordova导致Android平台停止工作

Question

I am using 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

I then upgraded my Cordova to the latest version (from 6.4.0 to 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

As you can see, I also upgraded my Android platform from android 6.0.0 to android 6.2.3 .

Since then, I cannot get my Cordova plugins to work on Android. iOS and browser all still works fine.

If I run it on an Android device or emulator, it loads the app, but does not show the Splash Screen, or get the Geolocation, allow Firebase login, etc. It looks like all Cordova plugins for Android are not working.

When I run in Android Studio, I get the following over and over in the logs:

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

It appears as if the install of the latest Android Platform (6.2.3) has broken the app.

Any suggestions welcome.

UPDATE

Now I try uninstall the Android platform and reinstall version 6.0.0. But I get errors:

cordova platform remove android

        You may get more insight by running the Cordova command above directly.

But:

cordova platform ls

  android 6.0.0
  ios 4.3.1

then

cordova build android

I check my Android SDK in Android Studio, and I have all the latest installed (Android 6.0, 7.0 & 7.1).

So I upgrade back to the latest Android platform:

cordova platform remove android
ionic cordova platform add android@latest

Now it builds again with no errors, but I sit with the same problem of the Cordova Plugins not working, and the following in the logs:

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

Answer 1

Solved:

deleted node_modules

npm install

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

ionic cordova build android
