AB Measurements of CPobservables in B±→DK±and B±→Dπ±decays are presented where the Dmeson is reconstructed in the final states K±π∓, π±K∓, K+K−, π+π−, K±π∓π+π−, π±K∓π+π−and π+π−π+π−. This analysis uses a sample of charged Bmesons from ppcollisions collected by the LHCb experiment in 2011 and 2012, corresponding to an integrated luminosity of 3.0fb−1. Various CP-violating effects are reported and together these measurements provide important input for the determination of the unitarity triangle angle γ. The analysis of the four-pion Ddecay mode is the first of its kind.
