Same issue to me, i override onCreateInputConnection() in the RichEditor, it can delete image, but some character can not input from software keyboard.

@tochange yes, I did the same and had the same issue with characters. For now I added "remove" image to each photo, so user can delete it without backspace. That's not perfect solution but at least it works.

yeah, that maybe a solution, but i saved the html content in a html file then open it with my browser, i can delete image, is that something wrong in the editor.html or css file?

The reason is in default input connection of WebView

Same issue to me,how to delete ?

有最新的解决方案了么？

Yeah, it seems like images deletion does not work on Android 4.4 :(

How to solve this problem? Any one knows?

@tochange Hi, I override onCreateInputConnection() in the RichEditor, too.And I meet the same issue, Chinese character can not be inputed, I do not know why. Have you solve this problem?

Hi, I am the maintainer of the Kolab Notes App. We are using this lib for richtest capabilities, so thank you very much for this project!

Users of our app also reported issues with the Richeditor and image deletion and text selection. It seems that this problems just occur on Cyanogenmod powered devices, as you can read in the issue comments here: konradrenner/kolabnotes-android#128

Maybe this information helps solving the issue. Keep the good work going ;-)

FYI, with the follow code,it work for me ! you can have a try ,good luck !
`@Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
CustomInputConnection connection = new CustomInputConnection(this, false);
outAttrs.inputType = InputType.TYPE_NULL;
outAttrs.imeOptions = EditorInfo.IME_ACTION_NONE;
outAttrs.initialSelStart = -1;
outAttrs.initialSelEnd = -1;

return connection;

}
public class CustomInputConnection extends BaseInputConnection {

public CustomInputConnection(View targetView, boolean fullEditor) {
    super(targetView, fullEditor);
}
@Override
public boolean deleteSurroundingText(int beforeLength, int afterLength) {
    // magic: in latest Android, deleteSurroundingText(1, 0) will be called for backspace
    if (beforeLength == 1 && afterLength == 0) {
        // backspace
        return super.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DEL))
                && super.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_DEL));
    }

    return super.deleteSurroundingText(beforeLength, afterLength);
}

}`

i solve the problem like this:
`
@OverRide
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
outAttrs.actionLabel = null;
outAttrs.inputType = InputType.TYPE_NULL;
final InputConnection con = new BaseInputConnection(this, false);
InputConnectionWrapper public_con = new InputConnectionWrapper(
super.onCreateInputConnection(outAttrs), true) {
@OverRide
public boolean deleteSurroundingText(int beforeLength, int afterLength) {
if (beforeLength == 1 && afterLength == 0) {
return this.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DEL))
&& this.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_DEL));
}
return super.deleteSurroundingText(beforeLength, afterLength);
}

        @Override
        public boolean sendKeyEvent(KeyEvent event) {
            if (event.getKeyCode() == KeyEvent.KEYCODE_DEL) {
                return con.sendKeyEvent(event);
            } else {
                return super.sendKeyEvent(event);
            }
        }
    };
    try {
        return public_con;
    } catch (Exception e) {
        return super.onCreateInputConnection(outAttrs);
    }
}

`

the answer is form stack overflow
