Is the onClick method being called? Are there any exceptions in the logcat output?

Thanks for answer. I copy logCat and past here:

Is that all? There aren't even messages about the app being started, so it doesn't seem to be the full output. Also:

I unistalled the program on the phone and run the program again. I copy everything writes in logCat tab:

I dont know what should i know the onClick method being called or not? Please explain for me.
Thank you. Cheers.

You can put a Log.i method call into the onClick handler.

I edit the loyaltier.java class:

Do i correct write log.i("test","I AM HERE"); ? I copy logCat and paste in below:

Where is my problem? How to fix it?
Thank you. Cheers.

If that's really the entire logcat output - and it doesn't really look like it is, you should verify that writing to the log works by adding more Log.i calls to your code, e.g. at the start of the onCreate method- then it would seem that the onClick handler is not being called.

Thanks.I download my program and if you can please read my code and say to me, what is my problem? Cheers.

I'm not sure what the problem is. That's why I suggested you start debugging the issue by putting log statement all over the code, so that you can be sure about which code is executed, and which is not. So far, I'm not even convinced that logging works, though.

I couldnt see logCat of previous my program because i write other program again and add log.i() function to my code. I write the code and logCat of program. I think when button clicked, the program not load web page. Why? Please please help me.

Are you really using spaces in your android_id attributes, or is that just an artifact of copy/paste?

Edit: Scratch that; I now see that it's a browser thing.

Thanks for answer.
I also ask this question in stackoverflow site and they say to me that i forgot add internet permission to AndroidManifest.xml and i add this to androidManifest.xml, the program runs

but when i changed my code and add Go.java to my project and changed MainActivity , the program not runs again

Why? Where and what is the problem?

stackoverflow

Sorry for my questions.
Thank you.
Cheers.

You probably didn't change it everywhere it needs to be changed, like in the manifest. Are there any exceptions in the stack trace?

Thanks for help

I copy MainActivity and Go.java and strings and ... in below. Where is the problem? Do i have any problem in code? if you need any file of my program, please tell me, so i write that.

Go.java

MainActivity:

Activity_main.xml:

strings.xml:

AndroidManifest.xml:

Cheers.

Start with this:

(I didn't really mean "stack trace", I meant "logcat output", but either way, the important part is "are there any exceptions?")
