Environement：私が間違っているのどこで

tns --version 
3.1.3 

"tns-android": { 
     "version": "3.1.1" 
    } 

？助けてください。前もって感謝します。

Answer 1

私はActivityのInstrumentatedを渡そうとしていました。したがって、解決方法は次のとおりです。

import * as app from 'application';  
let activity = app.android.foregroundActivity; 

また、wechatアプリがデバイスにインストールされていることを確認してください。
