App to retrieve cell number and then call web service on a remote server

straygrey — Wed, 22 May 2013 12:06:36 GMT

I need to write an app that is able to retrieve the users phone number from the users SIM card and then call a web service on a remote site where further processing takes place.
From what I have googled so far there is a possibility of getting the cell number via

Code:

private String getMyPhoneNumber(){

    TelephonyManager mTelephonyMgr;

    mTelephonyMgr = (TelephonyManager)

        getSystemService(Context.TELEPHONY_SERVICE); 

    return mTelephonyMgr.getLine1Number();

}



private String getMy10DigitPhoneNumber(){

    String s = getMyPhoneNumber();

    return s.substring(2);

}

Code:

TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

// get IMEI

String imei = tm.getDeviceId();

String phone = tm.getLine1Number();

but now how do I make a call to a remote web service passing this cell number?

CyanogenMod 10.1 - Afrikaans

isimobile — Tue, 14 May 2013 17:39:55 GMT

Hi Guys,

I have been contributing to the cm 10.1 project by adding the missing Afrikaans translations into Android so if you use cm 10.1 custom ROM, the RC's are out and it should be available under language options. I hope you find it useful or not. :-)

smart phones development

straygrey — Mon, 13 May 2013 12:16:10 GMT

I have heard a rumour that it is possible to create apps for smart phones using only HTML5, CSS3 & JavaScript.
Up till now I have used PhoneGap to make my programs cross platform compatible, but I have been given to understand that with only HTML5, CSS3 and Javascript one can create crossplatform applications(Cross platform = Android, IOS and Blackberry).
Can someone please point me in the correct direction?

{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

tabHost.setup();

TabSpec spec1=tabHost.newTabSpec("TAB 1");
spec1.setContent(R.id.tab1);
spec1.setIndicator("Playlist");

spec2.setIndicator("Artist");
spec2.setContent(R.id.tab2);

TabSpec spec3=tabHost.newTabSpec("TAB 3");
