Question

我在Nexus 7上安装了AOSP android-5.0.2_r1。我写了一个简单的应用来从GPS传感器检索位置数据，但是从不调用onLocationChanged方法。下面是logcat，任何人都可以发现有什么问题吗？

以下是我的应用的代码：

public class MainActivity extends Activity {

//private PbdLocationManager pbdLocManager;
//private PbdDeviceManager pbdDevManager;
private final String TAG = "PbdTest";
//private MyReceiver receiver;

private int noLocations = 2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Log.d(TAG, "into Oncreate method");


    // Testing the LocationManager functions
    LocationManager locMgr = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    final MyLocationListener listener = new MyLocationListener();

    locMgr.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3000, 0, listener);

}

private final class MyLocationListener implements LocationListener{
    @Override
    public void onLocationChanged(Location location){
        try{
            double lat = location.getLatitude();
            double lon = location.getLongitude();
            String l = "LocationManager Longitude: " + lon + " Latitude: " + lat;
            Toast.makeText(getApplicationContext(), l ,Toast.LENGTH_SHORT).show();
            Log.d(TAG, "SUCCESS to call function");

        }
        catch (Exception e){
            Log.d(TAG, "FAILED to call function");
            e.printStackTrace();
        }
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras){}
    @Override
    public void onProviderEnabled(String provider){}
    @Override 
    public void onProviderDisabled(String provider){}
}

Answer 1

从物理角度检查是否有可能有GPS信号。

无法在Android-5.0.2_r1中获取GPS位置
