回答1:
Solved for me..on Device and Emulator.
Time,Date and Timezone should be correct if anything is wrong or even 1 min difference will give this exception.
回答2:
First Try to clear cookies before you init LinkedIn related object... Use Below Code
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.removeAllCookie();
Please update me if it works or not....
