Question

I try to use the NETWORK_PROVIDER to locate myself. When I run my application (on the emulator with eclipse and with my phone), I always detect the provider as disabled.

public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    // refresh button
    this.b1 = (Button)findViewById(R.id.b1);
    this.b1.setOnClickListener(this);

    this.lm = (LocationManager)getSystemService(LOCATION_SERVICE);
    String provider = LocationManager.NETWORK_PROVIDER;
    Location location = this.lm.getLastKnownLocation(provider);

    this.t1 = (TextView)findViewById(R.id.t1);
    if (location != null)
        this.t1.setText(location.toString());
    else
        if (lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER)==false)
            this.t1.setText("Provider disabled");
        else
            this.t1.setText("No location, please wait");

    int t = 5000;
    int distance = 5;
    lm.requestLocationUpdates(provider, t, distance, myLocationListener);
}

public void onClick(View view){
    Location location = this.lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
    if (location != null)
        this.t1.setText(location.toString());
    else
        this.t1.setText("Refreshed but no location");

}

I checked, the option in Settings > Location > Use wireless networks is enabled.

edit: code corrected as mentioned by NickT but still receive no location when pushing the button

I think you meant to write

if (!lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
   this.t1.setText("Provider disabled"); // always get this

didn’t you?

As it stands you display ‘disabled’ when it’s enabled.
