android onclick调试模式下的奇怪行为true false

Question

I found a weird behavior(in my opinion).

I created an activity with a simple click action onLogon(View view) . (No onclick listener!) and in my layout.xml , I just added a button and used android:onClick="onLogon"

Running this in debug mode on my android phone (kitkat) was no problem. But as soon as I deployed it without debug mode, this gave errors.

I had to change the onLogon(View view) with an onclick listener to something like this.

Button mSignInButton = (Button) findViewById(R.id.btnLogon);
        mSignInButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                attemptLogin();
            }
        });

This last way of handling click events seems to work in debug, deploy and when deploying through the play store.

I understand why the onclick handler is the prefered way. I don't understand the difference in behavior between debug and non debug.

Maybe someone can explain this??
