I called them before: page.AddAnnotMarkup(m_index1, m_index2, 0);
public void OnPDFSelectEnd()
	{
		PDFPos pos = m_view.vGetPos((int)myRects[0], (int)myRects[1]);
		PDFVPage vpage = m_view.vGetPage(pos.pageno);
		Page page = vpage.GetPage();
		if( page != null )
		{
			page.ObjsStart();
			float pt[] = new float[2];
			pt[0] = pos.x;
			pt[1] = pos.y;
			int m_index1 = page.ObjsGetCharIndex(pt);
			m_index1 = page.ObjsAlignWord(m_index1, -1);
			pt[0] = vpage.ToPDFX(myRects[2], m_view.vGetX());
			pt[1] = vpage.ToPDFY(myRects[3], m_view.vGetY());
			int m_index2 = page.ObjsGetCharIndex(pt);
			m_index2 = page.ObjsAlignWord(m_index2, 1);
			page.AddAnnotMarkup(m_index1, m_index2, 0);
			m_view.vRenderSync(vpage);
			if( m_listener != null )
				m_listener.OnPageModified(vpage.GetPageNo());
		}

//		if( m_listener != null )
//			m_listener.OnSelectEnd(m_view.vGetSel());
	}
The result:

We have just tested your code, and it's working (the difference in only in the rect variables).

Make sure that index1 is smaller than index2:
float pt[] = new float[2];
		pt[0] = x1;
		pt[1] = y1;
		m_index1 = m_page.ObjsGetCharIndex(pt);
		pt[0] = x2;
		pt[1] = y2;
		m_index2 = m_page.ObjsGetCharIndex(pt);
		if( m_index1 > m_index2 )
		{
			int tmp = m_index1;
			m_index1 = m_index2;
			m_index2 = tmp;
		}
		m_index1 = m_page.ObjsAlignWord(m_index1, -1);
		m_index2 = m_page.ObjsAlignWord(m_index2, 1);

Did you try with other documents? if this happens with only one pdf, can you send it to us please.

Dear Mrawy,

We couldn't reproduce the issue usinf your file, can you reproduce it using the demo project?
Can you tells us the steps used to reproduce it?

Hi,
Steps to reproduce this issue using the demo project:
1- Modify PDFReader.class OnPDFSelecting method to be:
public void OnPDFSelecting(Canvas canvas, int[] rect1, int[] rect2)
	{
		Paint paint = new Paint();
		paint.setARGB(0x80, 0, 0, 0x80);
		if( rect2[1] > rect1[3] )
		{
			canvas.drawCircle( rect1[0], rect1[1], 5, paint);
			canvas.drawCircle( rect2[2], rect2[3], 5, paint);
			float[] rect = new float[3];
			rect[0] = rect1[0];
			rect[1] = rect1[1];
			rect[2] = rect2[2];
			rect[3] = rect2[3];
			myRects = rect;
		}
		else
		{
			canvas.drawCircle( rect2[0], rect2[1], 5, paint);
			canvas.drawCircle( rect1[2], rect1[3], 5, paint);
			float[] rect = new float[4];
			rect[0] = rect2[0];
			rect[1] = rect2[1];
			rect[2] = rect1[2];
			rect[3] = rect1[3];
			myRects = rect;
		}
	}
2- Modify PDFReader.class OnPDFSelectEnd method to be:
public void OnPDFSelectEnd()
	{
		PDFPos pos = m_view.vGetPos((int)myRects[0], (int)myRects[1]);
		PDFVPage vpage = m_view.vGetPage(pos.pageno);
		Page page = vpage.GetPage();
		if( page != null )
		{
			page.ObjsStart();
			float pt[] = new float[2];
			pt[0] = pos.x;
			pt[1] = pos.y;
			int m_index1 = page.ObjsGetCharIndex(pt);
//			m_index1 = page.ObjsAlignWord(m_index1, -1);
			pt[0] = vpage.ToPDFX(myRects[2], m_view.vGetX());
			pt[1] = vpage.ToPDFY(myRects[3], m_view.vGetY());
			int m_index2 = page.ObjsGetCharIndex(pt);
//			m_index2 = page.ObjsAlignWord(m_index2, 1);
			page.AddAnnotMarkup(m_index1, m_index2, 0);
			m_view.vRenderSync(vpage);
			if( m_listener != null )
				m_listener.OnPageModified(vpage.GetPageNo());
		}

//		if( m_listener != null )
//			m_listener.OnSelectEnd(m_view.vGetSel());
	}
Or use attached PDFReader.class

Dear Mrawy,

Try the following implementation (passing directly the rect values to the select end listener):

Change the OnPDFSelectEnd in PDFViewListener to:
public void OnPDFSelectEnd(float x1, float y1, float x2, float y2);
In PDFView.motionSelect change the call to the listener to:
if( m_listener != null ) m_listener.OnPDFSelectEnd(m_holdx, m_holdy, m_movex, m_movey);
And finally change the implementation of the listener itself as:
public void OnPDFSelectEnd(float x1, float y1, float x2, float y2)
	{
		PDFPos pos = m_view.vGetPos((int)x1, (int)y1);
		PDFVPage vpage = m_view.vGetPage(pos.pageno);
		Page page = vpage.GetPage();
		if( page != null )
		{
			page.ObjsStart();
			float pt[] = new float[2];
			pt[0] = pos.x;
			pt[1] = pos.y;
			int m_index1 = page.ObjsGetCharIndex(pt);
			pt[0] = vpage.ToPDFX(x2, m_view.vGetX());
			pt[1] = vpage.ToPDFY(y2, m_view.vGetY());
			int m_index2 = page.ObjsGetCharIndex(pt);
			if( m_index1 > m_index2 )
			{
				int tmp = m_index1;
				m_index1 = m_index2;
				m_index2 = tmp;
			}
			m_index1 = page.ObjsAlignWord(m_index1, -1);
			m_index2 = page.ObjsAlignWord(m_index2, 1);
			page.AddAnnotMarkup(m_index1, m_index2, 0);
			m_view.vRenderSync(vpage);
			if( m_listener != null )
				m_listener.OnPageModified(vpage.GetPageNo());
		}

//		if( m_listener != null )
//			m_listener.OnSelectEnd(m_view.vGetSel());
	}
