我只不過是監聽了我的Button事件(setOnClickListener),沒有做其他任何事,真讓我搞不懂到底這IDE是發生了什麼事!!
後來查到只要在 build.gradle(Module: app)中的android{}底下的defaultConfig{}裡面加上multiDexEnabled true
就可以正確運行了

不過,這好像不是唯一個解決辦法,而且加入這行會使得每次在build的時候花費很多時間。經過爬文之後發現,原來是method只要大於65k就會有這情況發生,這些method不只是我們自己寫的method,就連你improt的也算喔~~

所以只好到build.gradle(Module: app)中的android{}底下的dependencies{}中,找出根本沒有使用到的library將它移除,這情況就可以解決了。

如果每個library都有用到,那只好整理一下你的code吧!
