If this thread was constructed using a separate Runnable run object, then that Runnable object's run method is called; otherwise, this method does nothing and returns.

Usage

From source file:co.edu.uniajc.vtf.ar.ARViewActivity.java

public void callARView() {
    ExtendedApplicationContext loContext = (ExtendedApplicationContext) this.getApplication();
    ArrayList<PointOfInterestEntity> loPoints = loContext.getBufferPoints();
    if (loPoints != null) {
        this.coPois = this.createJsonArray(loPoints).toString();
        //here we create a thread to call the AR View
        final Thread loThread = new Thread(this.coLoadData);
        loThread.run();
    }// ww  w.ja  v a 2 s . com
