Working with an emulator or device's file system
DDMS provides a File Explorer tab that allows you to view, copy, and delete files on the
device. This feature is useful in examining files that are created by your application or if
you want to transfer files to and from the device.
To work with an emulator or device's file system:
In the Devices tab, select the emulator that you want to view the file system for.
To copy a file from the device, locate the file in the File Explorer and click the Pull file
button.
To copy a file to the device, click the Push file button on the File Explorer tab.
Examining thread information
The Threads tab in DDMS shows you the currently running threads for a selected process.
In the Devices tab, select the process that you want to examine the threads for.
Click the Update Threads button.
In the Threads tab, you can view the thread information for the selected process.
Starting method profiling
Method profiling is a means to track certain metrics about a method, such as number
of calls, execution time, and time spent executing the method. If you want more
granular control over where profiling data is collected, use the startMethodTracing() and
stopMethodTracing() methods. For more information about generating trace logs, see
Profiling and Debugging UIs.
Before you start method profiling in DDMS, be aware of the following restrictions:
Android 2.1 and earlier devices must have an SD card present and your application must
have permission to write to the SD card.
Android 2.2 and later devices do not need an SD card. The trace log files are streamed
directly to your development machine.
To start method profiling:
On the Devices tab, select the process that you want to enable method profiling for.
Click the Start Method Profiling button.
Interact with your application to start the methods that you want to profile.
Click the Stop Method Profiling button. DDMS stops profiling your application and opens
Traceview with the method profiling information that was collected between the time you
clicked on Start Method Profiling and Stop Method Profiling.
