    Read the Clipboard, check against the input and the time the input is "typed". If the Clipboard has the same text and it is too fast, delete the pasted input.

    If you are using API level 11 or above then you can stop copy,paste,cut and custom context menus from appearing by.

    edittext.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
    
                public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
                    return false;
                }
    
                public void onDestroyActionMode(ActionMode mode) {                  
                }
    
                public boolean onCreateActionMode(ActionMode mode, Menu menu) {
                    return false;
                }
    
                public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
                    return false;
                }
            });
    

    Returning false from onCreateActionMode(ActionMode, Menu) will prevent the action mode from being started(Select All, Cut, Copy and Paste actions).

    For smartphone with clipboard, is possible prevent like this.

    editText.setFilters(new InputFilter[]{new InputFilter() {
            @Override
            public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
                if (source.length() > 1) {
                    return "";
                }  return null;
            }
        }});

    Try to use.

    myEditext.setCursorVisible(false);
    
           myEditext.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
    
            public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
                // TODO Auto-generated method stub
                return false;
            }
    
            public void onDestroyActionMode(ActionMode mode) {
                // TODO Auto-generated method stub
    
            }
    
            public boolean onCreateActionMode(ActionMode mode, Menu menu) {
                // TODO Auto-generated method stub
                return false;
            }
    
            public boolean onActionItemClicked(ActionMode mode,
                    MenuItem item) {
                // TODO Auto-generated method stub
                return false;
            }
        });

    Similar to GnrlKnowledge, you can clear the Clipboard

    http://developer.android.com/reference/android/text/ClipboardManager.html

    If you want, preserve the text in the Clipboard, and on onDestroy, you can set it again.

    I've tested this solution and this works

        mSubdomainEditText.setLongClickable(false);
        mSubdomainEditText.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
    
          public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            return false;
          }
    
          public void onDestroyActionMode(ActionMode mode) {
          }
    
          public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            return false;
          }
    
          public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            return false;
          }
        });
