ActivityNotFoundException in generating qrcode

Question

I am trying to generate qrcode via intent, but I'm always getting ActivityNotFoundException. I have my core.jar in my lib.

Here is my code:

intent = new Intent("com.google.zxing.client.android.ENCODE");
    intent.putExtra("ENCODE_TYPE", "TEXT_TYPE");
    intent.putExtra("ENCODE_DATA", "Hello World!");
    startActivity(intent);

And here is the log:

import a zxing library project in your workspace from here.
create a new project from a library project.It will work fine.

Also you can visit this link for implementation.

This is irrelevant to integrating by Intent, and not recommended anyway. The answer is much simpler. – Sean Owen Oct 12 '12 at 07:26

This means that Barcode Scanner is not installed. You are responsible for catching ActivityNotFoundException and handling it, like prompting the user to install it.

Better still, use the android-integration code in the original zxing project. It's two classes, and it wraps up all of the details like this in a simple API. http://code.google.com/p/zxing/wiki/ScanningViaIntent

Do I need Barcode Scanner to show the QRCode? I'm sorry for my dumb questions. – Emmannuel Gozon Oct 12 '12 at 09:26
Oops! Now, I'm aware of about this `Exception` Actually, i thought its because of `.jar` file not imported properly. Thanks for your information. – Praveenkumar Oct 12 '12 at 09:42
