Re: [andmore-dev] Jfreechart and DDMUILib

[David Carver <d_a_carver@xxxxxxxxx>]

It is one class.  I launched the DDMS last night and the chart is used to show the Graph for the Heap Usage and Memory Usage.    We could fork it and probably pretty easily replace it with BIRTs charting engine or another charting engine that could pass IP.  It is just a matter of time with everything else that needs to be done as well.

Is there any hope that the parts that created the chart can be isolated and have a compliant chart library used? i.e. Option 2? 

This may have to be "Option 3 for now, but we want to get to Option 2". Guess we could just put a big button there for now and pull the chart. I think we can get by without the chart if it's the only blocker leading up to a release date.

Well, we hit our first stumbling block.  The DDMUILib which provides the UI for the DDMS perspective within eclipse, makes uses in one class jfreechart.  Unfortunately this is LGPL, and jfreechart has been rejected for our reuse in Andmore by Eclipse Foundation.

DDMUILib doesn't seem to be maintained by google any more as I had to go back to a JB branch to find the source in the platform/sdk. So, our options are as follows:

1. Provide a way to launch the standalone DDMS app from the SDK.
2. Fork the DDMUILib and use something else other than jfreechart to provide the Event Graph within eclipse.
3. Don't distribute DDMS support.

Option 3 I don't like, option 1 is a bit more tolerable but doesn't provide a good integrated experience.

Not sure how difficult it would be do to do option 2 as I haven't looked too deeply on what it is being used for.


Here is the relevant CQ.

The class we have a problem with is DisplayGraph in the ddmuilib.
