This document discusses various developer tools available for Android emulators and devices, including: 1) Emulator acceleration features like VM acceleration for x86 systems and GPU acceleration for graphics-intensive apps. 2) Emulator debugging tools like the telnet interface, hierarchy viewer, and dumpsys for checking app memory usage and device states. 3) Systrace for profiling app and system performance across CPU, memory, and disk I/O. 4) Lint for catching bugs and optimizing app quality, and MAT and hprof for memory analysis. 5) DDMS and tracer for remote device control and method tracing via ADB.
