Android Build Error with Latest Release

[froggyware]

Hi,

I just downloaded the latest release from August, now I have the following build error:

[proguard] Warning: com.steema.teechart.tools.SeriesBand$1: can't find referenced class org.w3c.dom.events.Event
[proguard] Warning: com.steema.teechart.tools.SeriesBand$2: can't find referenced class org.w3c.dom.events.Event

I do not have this error with the previous release.

Building for Android 4.0.3 API

What happened? How can I resolve this.

Right now I rolled back to the previous release.

thanks,

Hi,

SeriesBand.java hasn't been changed between v3.2012.0202 and v3.2012.0808.
I've tried the code below in a simple testing project and it seems to work fine for me here. Could you please give it a try and tell us if it works fine for you?

Code: Select all

        tChart1.getAspect().setView3D(false);
        tChart1.getLegend().setVisible(false);

        FastLine fastLine1 = new FastLine(tChart1.getChart());
        fastLine1.fillSampleValues();
       
        FastLine fastLine2 = new FastLine(tChart1.getChart());
        fastLine2.fillSampleValues();
        
        SeriesBand band1 = new SeriesBand(tChart1.getChart());
        band1.setSeries(fastLine1);
        band1.setSeries2(fastLine2);

If you still have problems with it, please try to arrange a simple example project we can run as-is to reproduce the problem here.

Thanks in advance.

Hi,

I'm sorry, I don't think i was very clear. The problem comes up when making a Release Build with Proguard enabled (not while in development). The issue seems to be with ProGuard (as usual) EG::

> ant release
.....

then the build fails with the following error:


[proguard] Warning: com.steema.teechart.tools.SeriesBand$1: can't find referenced class org.w3c.dom.events.Event
[proguard] Warning: com.steema.teechart.tools.SeriesBand$2: can't find referenced class org.w3c.dom.events.Event

I am currently unable to release using this version of TeeChart and has to revert back to the older version. I am currently building against Android 4.0.3 API

Hi froggyware,

Does the version work fine without ProGuard? Does the application work fine with ProGuard in spite of the warning message? If that's the case then you may want to look at some ProGuard warning suggestions: http://proguard.sourceforge.net/manual/ ... olvedclass searching for "can't find referenced class" there or related posts at StackOverflow:

Hi froggyware,

Thanks for your feedback, I'm glad to hear that.

Hi,

After sometime I came back to this issue again.
Looking at the source code of SeriesBand. There is the following import

import org.w3c.dom.events.Event

This does not appear to be correct. Should it not be:

import com.steema.teechart.events.Event

??
thx.

Hello,

Thank you for the error report. The import line, import org.w3c.dom.events.Event; is indeed in the latest (downloadable) source. As you say, it shouldn't be there.

We're not sure where the error has slipped in from. The line can be removed completely, it is not required.

Apologies for the error and for your time it has taken. We'll correct the publicly downloadable version and replace it.
