Sure, first bluetooth detection on Android emulator is not supported
on Wind7 so i used VirtualBox to run it on Linux2.4, so the bluetooth
features are supported by the Host OS and the emulator, but the thing
is that the app is not detecting any devices (My phone...)
This is my code:
package android.mgo.helloandroid;
import java.util.Set;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothDevice;
import android.content.Intent;
public class UIdrawingActivity extends Activity implements
OnClickListener {
/** Called when the activity is first created. */
Button startdetectingbtn;
Button clearbtn;
EditText roomnumbertext;
EditText bluetoothdetect;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
bluetoothdetect = (EditText)findViewById(R.id.detectedsignal);
clearbtn = (Button)findViewById(R.id.clearbtn);
View startdetectingbtn = findViewById(R.id.startdetectingbtn);
startdetectingbtn.setOnClickListener(this);
clearbtn.setOnClickListener(new OnClickListener() {
// clear the text boxes
@Override
public void onClick(View v) {
bluetoothdetect.setText("");
}
});}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.startdetectingbtn:
EditText bluetoothtext =
(EditText)findViewById(R.id.detectedsignal);
// Getting the Bluetooth adapter
BluetoothAdapter adapter =
BluetoothAdapter.getDefaultAdapter();
bluetoothtext.append("\nAdapter: " + adapter);
// Check for Bluetooth support in the first place
// Emulator doesn't support Bluetooth and will return null
if(adapter==null) {
bluetoothtext.append("\nBluetooth NOT supported. Aborting.");
return;
}
else{
// Starting the device discovery
bluetoothtext.append("\nStarting discovery...");
adapter.startDiscovery();
bluetoothtext.append("\nDone with discovery...");
// Listing paired devices
bluetoothtext.append("\nDevices Paired:");
Set<BluetoothDevice> devices =
adapter.getBondedDevices();
for (BluetoothDevice device : devices)
{
bluetoothtext.append("\nFound device: " +
device);
}
}
}
}
}
and the following is Manifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
package="android.mgo.helloandroid"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="3" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".UIdrawingActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission
android:name="android.permission.BLUETOOTH_ADMIN" />
</manifest>
