I am able to bold/unbold Italic/unitalic the edittext but in one scenario when I bring my end selection pointer towards start selection pointer and then click the italic or bold button then it throws error and crash my app. I spent the whole day but couldn't figure it out the reason and solution. Please help.

my coding for italic style is the same athe s bold text

 private void boldText2()
 int typeface = Typeface.NORMAL;
 Spannable str = texto.getText();
 int selStart = texto.getSelectionStart();
 int selEnd = texto.getSelectionEnd();
 StyleSpan styleSpans = texto.getText().getSpans(selStart, selEnd, StyleSpan.class);

 for (StyleSpan styleSpan : styleSpans) 
 int oldStyle = styleSpan.getStyle();
 typeface = oldStyle;
 int spanStart = str.getSpanStart(styleSpan);
 int spanEnd = str.getSpanEnd(styleSpan);

 if (oldStyle == Typeface.BOLD_ITALIC) 
 str.setSpan(new StyleSpan(Typeface.ITALIC), spanStart, spanEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + " spanStart: " + spanStart + " spanEnd: " + spanEnd);
 
 if(oldStyle == Typeface.BOLD) 
 str.removeSpan(styleSpan);
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + " spanStart: " + spanStart + " spanEnd: " + spanEnd);
 

 if (spanStart < texto.getSelectionStart()) 
 str.setSpan(new StyleSpan(oldStyle), spanStart, selStart, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "spanStart < texto.getSelectionStart");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + " spanStart: " + spanStart + " spanEnd: " + spanEnd);
 

 if (spanEnd > texto.getSelectionEnd()) 
 str.setSpan(new StyleSpan(oldStyle), selEnd, spanEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "spanEnd > texto.getSelectionEnd()");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + " spanStart: " + spanStart + " spanEnd: " + spanEnd);
 

 

 if (typeface != Typeface.BOLD) 
Log.d("TAG", "Bolding section entered");
 if (styleSpans.length > 0) 
 int lastSpanEnd = 0;
 for (StyleSpan styleSpan : styleSpans) 
 int oldStyle = styleSpan.getStyle();
 int spanStart = str.getSpanStart(styleSpan);
 int spanEnd = str.getSpanEnd(styleSpan);

 if (spanStart > lastSpanEnd) 
 str.setSpan(new StyleSpan(Typeface.BOLD), lastSpanEnd, spanStart, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "spanStart > lastSpanEnd and is bolded 1st if condition");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + " spanStart: " + spanStart + " spanEnd: " + spanEnd);
 

 lastSpanEnd = spanEnd;
 str.removeSpan(styleSpan);


 if (spanStart < texto.getSelectionStart()) 
 str.setSpan(new StyleSpan(oldStyle), spanStart, selStart, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "spanStart < texto.getSelectionStart()");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + " spanStart: " + spanStart + " spanEnd: " + spanEnd);
 

 if (spanEnd > texto.getSelectionEnd()) 
 str.setSpan(new StyleSpan(oldStyle), selEnd, spanEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "spanEnd > texto.getSelectionEnd()");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + " spanStart: " + spanStart + " spanEnd: " + spanEnd);
 

 if (oldStyle == Typeface.ITALIC) 
 str.setSpan(new StyleSpan(Typeface.BOLD_ITALIC), spanStart, spanEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "Bold and Italic");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + "spanStart: " + spanStart + " spanEnd: " + spanEnd);
 
 

 if (selEnd != lastSpanEnd) 
 str.setSpan(new StyleSpan(Typeface.BOLD), selStart, selEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "selEnd != lastSpanEnd");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd);
 
 

 else 
 str.setSpan(new StyleSpan(Typeface.BOLD), selStart, selEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "Last else Bold");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd);
 
 

 

Gives me the following error

java.lang.IndexOutOfBoundsException: setSpan (-1 ... 0) starts before 0

for this code

 if (spanStart < texto.getSelectionStart()) 
 str.setSpan(new StyleSpan(oldStyle), spanStart, selStart, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 Log.d("TAG", "spanStart < texto.getSelectionStart()");
 Log.d("TAG", "selStart: " + selStart + " selEnd: " + selEnd + " spanStart: " + spanStart + " spanEnd: " + spanEnd);
