Activity Will Get Get Destroyed and Turn Back To Main Activity Error: E/AndroidRuntime: FATAL EXCEPTION: main

So I've been looking around stackoverflow + reddit + docs and still no solution about this, I've tried so many catch blocks but no clue I tried with bytearray but still the same problem. this was the error:

            catch (Exception e) {

            }        ''''code** '''

UPDATE::::: While Testing the encoding part was fine , but sometimes the decoding would completely get out the class/activity and would get to the main and show me the error above the code:::: UPDATE

If you have any solution or inteffered with this problem before please lmk. Thanks in Advance

The problem is in the structure of your try/catch block. You have something that is shaped like this:

try {
    encode.setOnClickListener(...);
    decode.setOnClickListener(...);
} catch (Exception e) {
    // ...
}

This will only catch exceptions thrown while setting the listeners. It will not have any effect on exceptions thrown from inside the listeners.

Try this instead:

decode.setOnClickListener(
    @Override
    public void onClick(View v) {
        try {
            decode.setText(...);
        } catch (Exception e) {
            // show toast message here
        }
    }
);
