It’s been an eventful second quarter for Google. The company shuttered its experimental online-only Nexus One store, saw its Android operating system grow by leaps and bounds, argued with China over censorship and closed its acquisition of AdMob, to name a few.

When the company releases its second-quarter financial results later today, investors will be mainly looking at Google’s online ad sales and the success of Google’s foray into the mobile space.

The closing of the Nexus One store could cause concern among investors, as could Google’s dispute with China, which was apparently resolved when the Chinese government renewed Google’s license to operate in the country last week.

The Internet search giant is expected to bring in $6.52 per share on $4.99 billion in sales, according to analysts polled by Thomson Reuters and Yahoo! Finance. Sales are expected to be slightly down from last year, when Google posted $5.52 billion in revenue, but earnings per share will be up from $4.66 reported in 2009.

Google’s stock slipped 1.4 percent in NASDAQ trading as of 9:30 a.m. Central. The company will report its earnings at 3:30 p.m. Central time today, after the close of the stock market.
