Hello,
Just downloaded the above mentioned project, opened the folder and in the libs folder there is a jar : indoor-positioning-1.0.jar
I think (Didn't try yet) you can do the following :
*Also i don't even know what the library does, but judging by the source code it's simple to do in B4A
Step 1
-copy this jar file to B4A additional libraries folder
-then add the add #AdditionalJar : indoor-positioning-1.0
Step 2
-In the same downloaded Project source code folder, navigate to : "src\de\hadizadeh\positioning\example"
-You will find 3 .Java files
Here is the kinda complicated part because you would need to understand what the code does :
-In the B4A project use the inline Java code :
#If JAVA
import de.hadizadeh.positioning.controller.PositionListener;
import de.hadizadeh.positioning.controller.PositionManager;
import de.hadizadeh.positioning.controller.Technology;
import de.hadizadeh.positioning.exceptions.PositioningException;
import de.hadizadeh.positioning.exceptions.PositioningPersistenceException;
import de.hadizadeh.positioning.model.PositionInformation;
#End if
The above 6 imports should be founded in the .Jar file
*Final step :
After importing the jar and the imports in the inline java, you will have to start copying and pasting the codes in the 3 java files mentioned before
Example (WifiTechnology.java to B4A inline java) :
#If JAVA
import android.content.Context;
import android.net.wifi.ScanResult;
import android.net.wifi.WifiManager;
import de.hadizadeh.positioning.controller.Technology;
import de.hadizadeh.positioning.model.SignalInformation;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class WifiTechnology extends Technology {
private WifiManager wifiManager;
public WifiTechnology(Context context, String name, List<String> keyWhiteList) {
super(name, keyWhiteList);
wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
}
@Override
public Map<String, SignalInformation> getSignalData() {
Map<String, SignalInformation> signalData =
new HashMap<String, SignalInformation>();
wifiManager.startScan();
List<ScanResult> scanResults = wifiManager.getScanResults();
for (final ScanResult scanResult : scanResults) {
signalData.put(scanResult.BSSID, new SignalInformation(scanResult.level));
}
return signalData;
}
}
#End If
-Hit run and it should compile without any problems :
