Try this.
Use this in your manifest permissions:

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

And in your activity use this:

Button new_button= (Button)findViewById(R.id.button_id);//check the button id in your layout xml 
new_button.setOnClickListener(new View.OnClickListener() {
     public void onClick(View v) {
     
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    String tel_number= "tel:"+"*123*03401234567*"+AMOUNT+"#";
    callIntent.setData(Uri.parse(tel_number));
    startActivity(callIntent);

      }
   });

Hope it helps. Please mark it correct if it is.

Thanks

Hi my name is Nick. I'm a college student for game art and design right now and I'm really getting into learning coding for both games and Android development. I really want to push myself and learn as much as I can. I've been running through codeacadamy's Java course to just start learning but would like advice on where else I should be looking for learning. I'm an artist so whole creative thinker thing, blah blah. But I'm always coming up with little tid bits of app ideas but I don't really know how to make any of them a reality. I was hoping that some of you could point me towards more resources and ways to learn AS MUCH AS POSSIBLE. I'm ambitious and am a quick learner. I want to develop a great app (who doesn't..) but I could use some direction on where to head to learn the most and how to become the best I can be. Advice on languages to learn, websites to visit to learn, places to get ideas to work off, general programming tips, ect. Whatever you can throw my way to help I'd love to hear. Feel free to overload me with info, lol I promise I won't crash Wink | ;)

I hope to gain as much info as I can and obtain it however I can. So whatever advice you can give to someone starting out I'd love to hear please. I appreciate your time to read this and hope with your help I'll eventually create a program or app that will make some sort of difference even if it's a small one. Code on!

Thanks,
Nick aka infamous X187Xx

I am really new into the whole android thing.I have always loved programming and its been a hobby. So, i started learning android couple of months back from the New Boston website. I just love the tutorials and now i have a dream to make my first app and see it in the hands of millions of people.Now, getting back to reality. I am also a fulltime college student which means balancing between my coursework and hobby. Now, i bet most of the experts may have gone through this management issues and can suggest me on my problem. My problem is that i get so carried away with developing my app that i forget to do my coursework and focus on my other programming languages(which i equally love). So, how do i actually not get carried away with my hobby and still make a fine balance between my coursework and my android app dream? Can you guys suggest some ideas which can help beginners like me to manage this sort of situation?

Self discipline! Make yourself a time-table to include both coursework and hobby - and keep to it!

Skipper: We'll fix it.
Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

The error log is telling you what the problem is, and where it occurs:

12-15 03:49:51.714: E/AndroidRuntime(1115): java.lang.NullPointerException
12-15 03:49:51.714: E/AndroidRuntime(1115): at uk.co.flumeland.reversi.RevHighScoreAdapter.getView(RevHighScoreAdapter.java:68)

Step through with your debugger and you should see what is null and why.

It is no use repeatedly posting the same data. I already explained that you need to use your debugger to trap where the error occurs and establish which variable is the null pointer, and what it is supposed to refer to.

This is your error

12-15 03:49:51.124: I/HighScores(1115): getScores() called
12-15 03:49:51.154: I/HighScores(1115): getScores() no scores found

So because is not finding any scores, it is returning a null value that is not handled

12-15 03:49:51.714: E/AndroidRuntime(1115):     at uk.co.flumeland.reversi.RevHighScoreAdapter.getView(RevHighScoreAdapter.java:68)

so just adding some error handling will fix your problem, easy

Hi and Happy New Year! Smile | :)

I'm using ksoap2 to call webservice's method and get exception when bilding envelope:

org.xmlpull.v1.XmlPullParserException: expected: START_TAG {http://schemas.xmlsoap.org/soap/envelope/}Envelope (position:START_TAG <definitions name="WebService" targetnamespace="http://93.174.51.130:7000/WebService">@10:58 in java.io.InputStreamReader@b3e83c10)

Name space in WSDL is "http://93.174.51.130:7000/WebService"

and namespace in code too, what problem, help me please!

I used search but can't find exactly answer

WSDL and code below, Thanks

I have following code for detection of attached USB.
{
UsbManager manager;
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Broadcast Receiver", Toast.LENGTH_SHORT)
.show();
onNewIntent(intent,context);
}

private void onNewIntent(Intent intent, Context context) {
String intentAction = intent.getAction();
Toast.makeText(context,"Action :" + intentAction, Toast.LENGTH_SHORT).show();
if(intentAction.equalsIgnoreCase("android.hardware.usb.action.USB_DEVICE_ATTACHED"))
{
Toast.makeText(context,"Dveice Attached", Toast.LENGTH_SHORT).show();
handleDevice(intent,context);
}
else if(intentAction.equalsIgnoreCase("android.hardware.usb.action.USB_DEVICE_ATTACHED"))
{
Toast.makeText(context,"Dveice Detached", Toast.LENGTH_SHORT).show();
}
else
{

}

}

private void handleDevice(Intent intent,Context context) {

manager = (UsbManager) context.getSystemService(UsbManager.EXTRA_DEVICE);
HashMap<string,usbdevice> list = manager.getDeviceList();
Iterator<usbdevice> it = list.values().iterator();
while(it.hasNext())
{
UsbDevice device = it.next();
openDevice(device);
}

}

private void openDevice(UsbDevice device) {
UsbDeviceConnection connection = manager.openDevice(device);
int fd = connection.getFileDescriptor();
Log.d("Fd :"+fd,"Text");
}
not firing the USB_DEVICE_ATTACHED event.
