Until recently, the Android SDK didn't provide a suite of analysis tools that offer as many options that are as tightly integrated as Instruments for iOS. However, there is now a package that comes bundled with the SDK called Device Monitor. Device Monitor is also a standalone tool that provides a GUI for a number of Android application debugging and analysis tools. These include DDMS, Tracer for OpenGL ES, Hierarchy Viewer, Systrace, Traceview, and the Perfect Pixel Magnification Viewer tool. You can launch Device Monitor from the SDK's /tools folder using the monitor command.
Note
A detailed discussion of Device Monitor is beyond the scope of this book. For more information on the tools provided in this suite, check out the documentation on each one at http://developer.android.com/tools/help/monitor.html.
