Embedded Software SKKU 14 1 Sungkyunkwan University Tizen v2.3 Application Profiling & Debugging

Embedded Software SKKU 14 2 Both native application and web application run on Tizen. There are two tools to profile and debug applications. Dynamic Analyzer –Profiling native applications Web Inspector –Profiling web applications Tizen Application Profiling

Embedded Software SKKU 14 3 A tool to profile and debug native applications Provide various templates Dynamic Analyzer

Embedded Software SKKU 14 4 Dynamic Analyzer Layout 1. Timeline chart –Shows data values over time as a chart 2. Snapshot, Call stack –Provides additional information about the data 3. Call trace –Shows the user API calls ① ② ③

Embedded Software SKKU 14 5 Shows data values over time as a chart Dynamic Analyzer: Timeline chart –CPU usage/frequency –Heap allocation Total, App allocated –Process size VSS, RSS, PSS –Memory –File read, write, open fd count –Screenshot –UI event key, touch, gesture, orientation events

Embedded Software SKKU 14 6 Shows user method call stack that occurs during an application execution All threads in the application –Call stack is provided by threads in the application Dynamic Analyzer: Call Trace Source code view –Hovering mouse cursor on the call, you can see original function code, including app and framework.

Embedded Software SKKU 14 7 Snapshot View –Shows current screen, CPU usage, process usage and available memory Dynamic Analyzer: Snapshot & Callstack Callstack View –Callstack of the selected API in call trace view ④ ① ② ③

Embedded Software SKKU 14 8 Display thread and synchronization objects in a tree format using a graph Dynamic Analyzer: Thread Analysis Chart –Yellow bar: API call –Orange area: possession of synchronization object (lock) –Violet arrow: interaction between threads –Grey area: waiting time for the acquiring that synchronization object

Embedded Software SKKU 14 9 Display UI component hierarchy and UI-related function profiling Dynamic Analyzer: UI Analysis Chart 1. Control –UI component hierarchy 2. Scene Transition –Scene transition history during app execution 3. UI Function Profiling –Profiling user-defined UI-related functions 4. Common Features –Additional information in the form of snapshot

Embedded Software SKKU Show information associated with file operations Dynamic Analyzer: File Analysis Chart –Green area: file was normally processed –Grey area: file was abnormally processed –Yellow area: file was not closed –Blue line: API has been used –Red line: API has failed –Purple area: read operation –Lime area: write operation
