我不知道Android开发，但如果您在使用该功能的问题，也许有卷曲在Android的类似的功能，将让你呼叫 https://graph.facebook.com/oauth/access_token？
    CLIENT_ID = APP_ID和放大器;     client_secret = APP_SECRET和放大器;     grant_type = fb_exchange_token和放大器;     fb_exchange_token = EXISTING_ACCESS_TOKEN

I don't know Android development, but if you're having issues with that function, maybe there's a similar function of CURL within Android that will allow you to call https://graph.facebook.com/oauth/access_token?
client_id=APP_ID& client_secret=APP_SECRET& grant_type=fb_exchange_token& fb_exchange_token=EXISTING_ACCESS_TOKEN
