Android phone in Windev Mobile 15.

[ Link removed - see below]

Hope this helps

YouTube says it's too long and was removed.

Re: How to access Android SDK (Contacts List example) - WM15

Hi All,

Sorry, the original post on youtube was removed because the video was about
a minute too long. Here's the edited version.

This is another example on how to access the contact list from an Android phone
in Windev Mobile 15

The new link is:


Hope this helps

Hi All,

Just in case you watch the video before it finishes processing (as youtube video quality usually improves once processing is complete), I've posted the java code below:

(Of course, I explain what all this code means in the video)

Create a global procedure and click the WL to convert the code to a Java method:

import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.content.ContentResolver;
import android.database.Cursor;
import android.provider.ContactsContract;

public static String chkContacts()

String contactId = null;
String phoneNo = null;
String contactName = null;
String hasPhone = null;

ArrayList myArr = new ArrayList();

Context context = getApplicationContext();
Cursor cursor = context.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

while (cursor.moveToNext()) {
contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

if (Integer.parseInt(hasPhone)==1) {
Cursor phone = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);

while (phone.moveToNext()){
phoneNo = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

myArr.add(contactName + ":" + phoneNo);

return myArr.toString();

And here's the code for the Button:

sContactList is string = chkContacts()

IF sContactList "" THEN
srecord is string = ExtractString(sContactList,firstRank,",")
WHILE srecord EOT
srecord = ExtractString(sContactList,nextRank,",")

Any questions, please let me know.

Re: How to Connect to a Bluetooth device Android SDK - WM15

Hello Georgio,
I wondered if you had examples of connecting to a specific Bluetooth device and
sending output. We are trying to connect to a bluetooth printer and send text.
We are able to detect bluetooth devices (with your help in the youtube video). We
are also able to find out the paired device name and mac address.
I would appreciate any help using the Windev Mobile 15 and Javacode.

Thank you.
Henry B.

I tried your code and get this error

Error returned:
Note: src\nl\ariezona\km_box\wdgen\GWDCPSET_GlobalProcedures.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Can you tell me how to fix things like this?
(I'm definitely not a java guy....)

Re: SOLVED How to access Android SDK (Contacts List example) - WM15 - New Video Link

Found it already:

ArrayList myArr = new ArrayList();
must be
ArrayList myArr = new ArrayList();

This comes up in Java 5 and later if you're using collections without type specifiers

Hi Arie,

The error "Recompile with -Xlint:unchecked for details." is a compiler command
passed by windev. This works on older versions of java but has since been

I usually run compilation without the flags.
