FPS testing in android application

Question

How can an android application developer test FPS (Frames per second) for their application? I'm talking about general application, not game.

It can be on emulator or phone.

I've been looking for this but have not found a way. It would be great, if any developer can shed light on this.

As mention by Guykun and kcoppock, if you are only using the View widgets or Canvas you normally don't look for FPS to determine visual performance.

As you don't mention what you are doing other than 'not a game' you may want to review how Android does drawing.

Most of the performance issues come from doing stuff on the UI thread. Use Strict Mode for finding problems.

Also use the tools to find performance hot spots:

And if you want more details of what's going on under the hood see the Google IO session on what they did for Hardware Accelerated Rendering

Google I/O 2011: Accelerated Android Rendering

Google has done additional work on UI performance and have presented sessions at Google IO available on Youtube:

GameBench is a nice tool.

Agree @Sistr - I posted this comment a long time ago. I do make it a point to mention it now.
