See ' Optimizing Your UI' to learn more about the Hierarchy Viewer tool and these panes. The Layout View pane (whose contents are not shown in Figure 2) reveals a block representation of the UI. The Tree Overview pane offers a smaller map representation of the entire Tree View pane. The Tree View pane presents a diagram of the activity's hierarchy of subclass objects. Hierarchy Viewer displays a multipane user interface. The layout hierarchy of the activity screen is shown in the Tree View pane. I highlighted the W2A activity object identified by its ca.javajeff.w2a package name, then clicked Hierarchy View to activate the Hierarchy Viewer tool. Underneath the highlighted device line is a list of currently visible subclass objects. The Devices tab shows all accessible devices, which happens to be the emulated Nexus 4 device in this example. The Devices tab appears when DDMS is selected. Figure 1 shows the resulting screen.įigure 1.

I then launched Android Device Monitor from Android Studio. You might remember from Part 1 that I used Android Studio to launch my W2A example app in the Nexus 4 emulator. If you prefer to run the tool from Android Studio, choose Tools > Android > Android Device Monitor. To launch Android Device Monitor from your command line, execute the monitor program in your Android SDK's tools directory. This tool can help you debug your application and profile its performance.

It also inspects the captured tracing information to highlight problems that it observes (from list item recycling to rendering content) and provide recommendations about how to fix them. A trace shows where time and CPU cycles are being spent, displaying what each thread and process is doing at any given time. Systrace: A tool for collecting and inspecting traces (timing information across an entire Android device).This tool can help you debug and optimize your user interface. Hierarchy Viewer: A graphical viewer for layout view hierarchies (the layout view) and for magnified inspection of the display (the pixel perfect view).It lets you capture OpenGL ES commands and frame-by-frame images to help you understand how your graphics commands are being executed. Tracer for OpenGL ES: A tool for analyzing OpenGL for embedded systems (ES) code in your Android apps.

Dalvik Debug Monitor Server (DDMS): A debugging tool that provides port-forwarding services, screen capture on the device, thread and heap information on the device, logcat, process, radio state information, incoming call and SMS spoofing, location data spoofing, and more.
