Hi,

I'm using TeeChart for my Android application. I have found out that my app crashes by touching the chart ( for example to scroll the chart back and forth) since I set chart.enabled(true). I know that scrolling was possible when I started working on my application a few weeks ago. When I thought about what changed since then, I noticed that I updated the tablet from Android 5 to Android 6.0.1 in the meanwhile. To make sure I created a new application with just a TeeChart in it and adding random values:

Code: Select all

 
chart1 = (TChart) findViewById(R.id.chart1);
chart1.addSeries(new Line()).fillSampleValues(40);

While touching the chart works fine on my phone with Android 4.1.2 , this leads to a crash on the tablet with Android 6.0.1 and throwing an segmentation error:

So do you have any suggestions for me how to to solve this problem?

Tanks in advance!
Kind regards

Hello,

This sounds as a problem we recently corrected so the next maintenance release should fix it.
See the following related tickets for the details:
http://bugs.teechart.net/show_bug.cgi?id=1263
http://bugs.teechart.net/show_bug.cgi?id=1107

In the meanwhile try disabling the hardware acceleration:

Code: Select all

  if (Build.VERSION.SDK_INT>10)
    tChart1.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
