How to make a phone call in a Android application

By -
This may a looks like a simple task. Actually it is a simple task. You can do it using few lines of code. But there are only few places which shows how to do it. So I decided to mention it here.


public void onCallButtonClicked(View view) {
String url = "tel:" + tpNo;
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(url));
intent.setData(Uri.parse(url));
startActivity(intent);
}

It has to be noted that this parser had to be generated as a .class file and dynamically added to the classpath. So the result was to use a bytecode manupulation library. There are few bytecode manuplulation libraries available as ASM and JavaAssist . I used JavaAssist for this.

So downloading each one is a very difficult task because there are problems like versions don't match, some libraries are outdated, etc.etc. There is a easy method. After installing the plugin Netbeans will automatically add the Jasper Reports library to its library collection. But it is missing one important...
