地図アプリを配置するために使用するこのコードがあります。Galaxy S2 デバイスでテストしたところ正常に動作しましたが、nexus 4 デバイスでテストしたところ、onLocationChanged
コールバックが呼び出されませんでした。私は何が間違っているのでしょうか?
これが私のアクティビティコードです:
public class BaseMapActivity extends FragmentActivity implements Injectable,
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener, LocationListener {
private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000;
private MapEntity component;
private boolean yetStarted = false;
private LocationClient mLocationClient;
private LocationRequest mLocationRequest;
private Location location;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_activity);
mLocationClient = new LocationClient(this, this, this);
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); // TODO
mLocationRequest.setInterval(5000); // TODO
mLocationRequest.setFastestInterval(5000); // TODO
replaceFragment(R.id.map_container, mapFragment);
// Agrega el fragment de extras
Fragment extrasFragment = component.getExtrasFragment();
replaceFragment(R.id.map_extras, extrasFragment);
}
@Override
protected void onStart() {
super.onStart();
mLocationClient.connect();
}
@Override
protected void onStop() {
if (mLocationClient.isConnected()) {
mLocationClient.removeLocationUpdates(this);
mLocationClient.disconnect();
}
super.onStop();
}
@Override
public void onConnected(Bundle arg0) {
mLocationClient.requestLocationUpdates(mLocationRequest, this);
location = mLocationClient.getLastLocation();
if (location == null) {
return;
}
Toast.makeText(this, "onConnected", Toast.LENGTH_SHORT).show();
}
@Override
public void onDisconnected() {
mLocationClient.removeLocationUpdates(this);
Toast.makeText(this, "onDisconnected. Please re-connect.",
Toast.LENGTH_SHORT).show();
}
@Override
public void onLocationChanged(Location location) {
component.setCenter(location);
String msg = "Updated Location: "
+ Double.toString(location.getLatitude()) + ","
+ Double.toString(location.getLongitude());
Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case CONNECTION_FAILURE_RESOLUTION_REQUEST:
switch (resultCode) {
case Activity.RESULT_OK:
break;
}
}
}
@SuppressLint("ShowToast")
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
if (connectionResult.hasResolution()) {
try {
connectionResult.startResolutionForResult(this,
CONNECTION_FAILURE_RESOLUTION_REQUEST);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
} else {
Toast.makeText(this, "An error ocurred getting current location",
Toast.LENGTH_SHORT);
}
}
}
奇妙なのは、あるデバイスでは機能するが、他のデバイスでは機能しないことです。
