This document provides information about Android developer tools including the emulator, dumpsys, procrank, traceview, systrace, tracer, lint, hprof, MAT, and ddmlib. It discusses capabilities of the emulator such as VM acceleration, GPU acceleration, compatibility across API levels, hardware acceleration benchmarks, scaling, and telnet interface. It also provides examples of using dumpsys, procrank, and ddmlib.
