Description yeray alonso 2016-05-31 03:22:09 EDT 
The application crashes with an "A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr ..." error.

I believe this has something to do with drawing manually at the main thread, while Android has to control the drawing thread.

You can do this to create a series and the DrawLine tool:

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

    final Candle candle1 = new Candle(tChart1.getChart());
    candle1.fillSampleValues();

    DrawLine drawLine1 = new DrawLine(tChart1.getChart());

However, as soon as you touch the screen and the first line tries to be drawn, the application crashes.

The same works perfectly fine in Swing and SWT.
