Ok Adding that. But at this moment it will reset only the last used component.

Probably this one should not give the error.

Unfortunately, it shows the same error message

That should have been a compilation error. Don't know why it was runtime.

Reset try no. 3

No error but no reset.

@TIMAI2 Do you think you can help in the code ?

The part that stores a String is :

lastText = textview.getText().toString();

lastText is a String, textview.getView() returns a SpannableStringBuilder, the toString() method converts it to a string.

First line of the reset function.
Here, the String is converted to a CharSequence.

text = (CharSequence)lastText;

text is a CharSequence.

Here, the object is made.

ss = new SpannableStringBuilder(text);

ss is a SpannableStringBuilder.

These are the only places where the problem can occur.

Other parts are working fine. (According to me.)

Does the toString() method somehow copy the styling too ?

38

Do you need to clear what was previously set in terms of styling ?

SHUBHAMR69 If you can design an extension to change the size of font for only the ten digits from ( 0 - 9) and the two brackets between the digits

No. I don't need to clear anything. I just set the styling, which automatically removes the previous styling.

Also, after many attempts to connect to the Companion, I got connected for almost half a minute.

I found out that we can easily reverse the text size.

For example, try setting relative size to 2 and then 0.5

[Couldn't check the reset() function. Got Disconnected.]
