The 30-year-old, who has notched just four goals in 22 league games this season, scored the last of his five international goals in September 2011 against Poland.
The Brazil-born forward was widely expected to lose his spot to Borussia Monchengladbach's Mike Hanke as Germany prepare their bid to end a 16-year title drought with victory at June's Euro 2012 tournament in Poland and Ukraine.
"It is the year of our big chance," coach Joachim Low told reporters. "The chance of achieving quite a bit in the tournament."
Germany will face France in Bremen next Wednesday without the injured Bastian Schweinsteiger, Mario Goetze, Lukas Podolski and Per Mertesacker.
The three-time European champions will also play friendlies with Switzerland on May 26 and Israel on June 1 before the start of the tournament.
