Clearing the single character before cursor position in EditText

With the below code i am replacing the all characters(if my edittext contains four a's all a's are removed here) that contains substring and the cursor position is goes to before first character in edittext field.

//getting cursor position 
int end = t1.getSelectionEnd();
//getting the selected Text
String selectedStr = t1.getText().toString().substring(end-1, end);
//replacing the selected text with empty String and setting it to EditText
t1.setText(t1.getText().toString().replace(selectedStr, ""));

How can i clear the single character before the cursor position(if my cursor is middle of the edittext) without changing the cursor position.

Perfect solution try this... Wherever you will put your cursor the value will gets remove from that position

  Editable editable = yourEditText.getText();
    int charCount = mDigits.getSelectionEnd();
    if (charCount > 0) {
    editable.delete(charCount - 1, charCount);
    }

I solved with this function:

int pos = editText.getSelectionStart();
if (pos > 0)
    String text = editText.getText().delete(pos - 1, pos).toString();

I think its late but still.

You can use SpannableStringBuilder.

//getting cursor position 
int end = t1.getSelectionEnd();
//getting the selected Text
SpannableStringBuilder selectedStr=new SpannableStringBuilder(t1.getText());
//replacing the selected text with empty String and setting it to EditText
selectedStr.replace(end-1, end, "");
edittext1.setText(selectedStr);
