当我在android studio 3.5上启动新项目时，它会显示“我的应用程序正在同步……”

Question

My android studio (ver 3.5) doens't sync, and shows "my application syncing..." forever. ( actually i couldn't wait more than 8 hours)

I'm beginner in android studio. first i've installed 3.2 ver and i had problems with Gradle which i couldn't solve. then i tried to update the SDK, NDK, Gradle and even whole android studio to ver3.5 .

now when i open android studio and create a project , it doesn't even sync! it shows me that my application is still syncing (and never sync)(even i tried proxy and other networks) And there shows 1 error which is:

3:29 AM: Gradle sync failed: loader constraint violation: loader (instance of com/intellij/ide/plugins/cl/PluginClassLoader) previously initiated loading for a different type with name "gnu/trove/TObjectHashingStrategy (6 s 311 ms)

I even cannot change the Gradle codes or any other codes inside the android studio...

Answer 1

尝试使“文件->使缓存无效/重新启动...”上的缓存无效

Answer 2

It seems like you are iranian. if you live in Iran you must use a VPN or proxy to use Android studio because of US sanction. a better way is to change your DNS introduced in https://shecan.ir/ .
