I am getting an error while building google api client in a fragment. The error I am getting is;
java.lang.ClassCastException: net.janusjanus.we4x4_v1.upload cannot be cast to com.google.android.gms.common.api.GoogleApiClient$OnConnectionFailedListener
I have implemented GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, and LocationListener
and requesting the build as following;
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
.addConnectionCallbacks(this)
.addOnConnectionFailedListener((GoogleApiClient.OnConnectionFailedListener) getActivity())
.addApi(LocationServices.API)
.build();
first I had a problem declaring the new GoogleApiClient.Builder where I declared it as ;
mGoogleApiClient = new GoogleApiClient.Builder(this)
underlined as an error, thus I had to try several ways to declare it, with getActivity() and getContext(). but I got the same error ?
Any idea on what I am doing wrong here and the correct way ?
Well simply in my case i had to declare the GoogleApiClient.Builder as following;
mGoogleApiClient = new GoogleApiClient.Builder(UploadPictures.this.getContext())
where UploadPictures is the fragment name.
Hope this could be helpful for someone.
implement GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, and LocationListener
#Override
public void onConnectionFailed(ConnectionResult result) {
}
#Override
public void onConnected(Bundle arg0) {
}
#Override
public void onConnectionSuspended(int arg0) {
}
#Override
public void onLocationChanged(Location location) {
}
And then change code to:
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();

I have a game on LibGDX. According to this
http://www.norakomi.com/tutorial_admob_part2_banner_ads1.php
instruction I created necessery methods in AndroidLauncher.java file. And in the core file, generated by AndroidLauncher.java, I have created the controller and also interface java file
( http://www.norakomi.com/tutorial_admob_part2_banner_ads2.php ).
The problem is that my game has several classes which extend one another and the corresponding condition, which I want to use for displaying adMob, is not that one to which method "initialize" gives "this" from AndroidLauncher.java file. But to download and to give request for adMob is possible only from AndroidLauncher.java, because another classes are in its own game view.
How to solve this?
This is the basic code from AndroidLauncher.java
public class AndroidLauncher extends AndroidApplication implements AdsController {
private static final String BANNER_AD_UNIT_ID = "ca-app-pub-3940256099942544/6300978111";
private static final String INTERSTITIAL_AD_UNIT_ID = "ca-app-pub-3940256099942544/1033173712";
AdView bannerAd;
InterstitialAd interstitialAd;
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
// Create a gameView and a bannerAd AdView
View gameView = initializeForView(new Stork2016(this), config);
setupBanner();
setupInterstitial();
// Define the layout
RelativeLayout layout = new RelativeLayout(this);
layout.addView(gameView, ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
layout.addView(bannerAd, params);
setContentView(layout);
config.useCompass = false;
config.useAccelerometer = false;
public void setupBanner() {
bannerAd = new AdView(this);
//bannerAd.setVisibility(View.VISIBLE);
//bannerAd.setBackgroundColor(0xff000000); // black
bannerAd.setAdUnitId(BANNER_AD_UNIT_ID);
bannerAd.setAdSize(AdSize.SMART_BANNER);
}
public void setupInterstitial() {
interstitialAd = new InterstitialAd(this);
interstitialAd.setAdUnitId(INTERSTITIAL_AD_UNIT_ID);
AdRequest.Builder builder = new AdRequest.Builder();
AdRequest ad = builder.build();
interstitialAd.loadAd(ad);
#Override
public void showInterstitialAd(final Runnable then) {
runOnUiThread(new Runnable() {
#Override
public void run() {
if (then != null) {
interstitialAd.setAdListener(new AdListener() {
#Override
public void onAdClosed() {
Gdx.app.postRunnable(then);
AdRequest.Builder builder = new AdRequest.Builder();
AdRequest ad = builder.build();
interstitialAd.loadAd(ad);
}
});
}
interstitialAd.show();
}
});
}
#Override
public boolean isWifiConnected() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
return (ni != null && ni.isConnected());
}
#Override
public void showBannerAd() {
runOnUiThread(new Runnable() {
#Override
public void run() {
bannerAd.setVisibility(View.VISIBLE);
AdRequest.Builder builder = new AdRequest.Builder();
AdRequest ad = builder.build();
bannerAd.loadAd(ad);
}
});
}
#Override
public void hideBannerAd() {
runOnUiThread(new Runnable() {
#Override
public void run() {
bannerAd.setVisibility(View.INVISIBLE);
}
});
}
}
And then we have file Stork2016.java in which we create AdsController to be able to use methods for adds in AndroidLauncher.java.
private AdsController adsController;
public Stork2016(AdsController adsController){
this.adsController = adsController;
}
#Override
public void create () {
adsController.showBannerAd();
batch = new SpriteBatch();
gsm = new GameStateManager();
music = Gdx.audio.newMusic(Gdx.files.internal("music.mp3"));
music.setLooping(true);
music.setVolume(0.5f);
music.play();
Gdx.gl.glClearColor(1, 0, 0, 1);
gsm.push(new MenuState(gsm));
}
And also we have interface java file AdsController.java
public interface AdsController {
public void showBannerAd();
public void hideBannerAd();
public void showInterstitialAd (Runnable then);
public boolean isWifiConnected();
}
So, as we can see in Stork2016 we have "gsm.push(new MenuState(gsm));" and in MenuState.java I have "gsm.set(new PlayState(gsm));". In PlayState.java there is the part of code:
#Override
public void update(float dt) {
handleInput();
updateGround();
....
if (tube.collides(bird.getBounds()))
gsm.set(new GameOver(gsm));
...
}
}
camera.update();
}
The condition "if" frome the above code I want to use to show interstitial adMob. But it is impossibe, because the contoller which takes methods from AndroidLauncher.java can be created only in Stork2016.java. And also in AndroidLauncher.java there is
View gameView = initializeForView(new Stork2016(this), config);
wich transfers "this" to Stork2016, where is the controller.
In my AndroidLauncher activity I start the game and initialize the Insterstitial ad. Then I initialize my interface which I call from inside the game, to trigger show/hide of the interstitial ad.
For example I have method showInterstitialAd() in my interface listener, then my implementation on Android would be:
#Override
public void showCoverAd() {
runOnUiThread(new Runnable() {
#Override
public void run() {
if (interstitialAd.isLoaded()) {
interstitialAd.show();
}
}
});
}
And on iOS-MOE:
#Override
public void showCoverAd() {
if (gadInterstitial.isReady()) {
gadInterstitial.presentFromRootViewController(uiViewController);
}
}
So you need the make sure that the interface listener knows about the interstitial ad, for example AndroidLauncher implements MyGameEventListener
In my case interface AdsController.java is implemented in AndroidLauncher.java:
public class AndroidLauncher extends AndroidApplication implements AdsController { ...
And then by this part of code:
View gameView = initializeForView(new Stork2016(this), config);
we send "this" to new class Strork2016.java.
And in the class Stork2016.java I create constructor:
private AdsController adsController;
public Stork2016(AdsController adsController){
this.adsController = adsController;
}
which lets us use methods from interface AdsController.java.
But only in this class Stork2016. If I want to use it in another class:
gsm.push(new MenuState(gsm));
this is impossible and this is the problem.
OK guys, I have solved the problem.
I had to create two consturctors in both classes: the main core class which is initialyzed from AndroidLauncher and in the class GameStateManager. Because the class, where I want admob intersitital to be called, is created by method gsm.push which is described in class GameStateManager. Actually, in GameStateManager there have already been constuructor, so I hade only to add necessary code to this constructor.
Here is my code. I am using scene builder. The code is not working.For first time it loads the hello1.html but in thread the hello2.html does not load.
public class TwavlController implements Initializable {
/**
* Initializes the controller class.
*/
#FXML public WebView webPane;
private Service<Void> back_thread;
private WebEngine engine;
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
engine = webPane.getEngine();
final String html_file = "hello1.html"; //HTML file to view in web view
URL urlHello = getClass().getResource(html_file);
engine.load(urlHello.toExternalForm());
run();
}
private File last_update,current;
public void run(){
back_thread = new Service<Void>() {
#Override
protected Task<Void> createTask() {
return new Task<Void>() {
#Override
protected Void call() throws Exception {
updateMessage("hello2.html");
return null;
}
};
}
};
engine.userAgentProperty().bind(back_thread.messageProperty());
back_thread.restart();
}
}
I'm not really clear what you're trying to do here, but I think maybe you are looking for
public void run(){
back_thread = new Service<Void>() {
#Override
protected Task<Void> createTask() {
return new Task<Void>() {
#Override
protected Void call() throws Exception {
Platform.runLater(() ->
engine.load(getClass().getResource("hello2.html").toExternalForm()));
return null;
}
};
}
};
back_thread.restart();
}
I am using this link https://stackoverflow.com/a/34626302/5761156 and taking reference from here https://gist.github.com/joshdholtz/4522551 but unable to understand why we need to override lifecycle methods such as on resume and on destroy . I tried not to override them and the maps then do not show? What am I doing wrong?
Specifically I am adding the gist lines which I find confusing
#Override
public void onResume() {
mapView.onResume();
super.onResume();
}
#Override
public void onDestroy() {
super.onDestroy();
mapView.onDestroy();
}
#Override
public void onLowMemory() {
super.onLowMemory();
mapView.onLowMemory();
}
I have a javafx design in the file javafx.fxml where the root element has the following attribute
fx:controller="de.roth.jsona.javafx.ViewManagerFX"
This controller class has a singleton machanism and is binded with some ui-elements.
public class ViewManagerFX {
private static ViewManagerFX instance = new ViewManagerFX();
#FXML
private Slider volumeSlider;
#FXML
private Label volumeLabel;
public IntegerProperty volumeValue = new SimpleIntegerProperty();
#FXML
private TabPane musicTabs;
public List<StringProperty> tabNames = new ArrayList<StringProperty>();
public static ViewManagerFX getInstance() {
return (instance);
}
public void initialize() {
// Volume
volumeSlider.valueProperty().bindBidirectional(volumeValue);
volumeLabel.textProperty().bindBidirectional(volumeValue, new Format() {
#Override
public StringBuffer format(Object obj, StringBuffer toAppendTo,
FieldPosition pos) {
toAppendTo.append(obj);
toAppendTo.append("%");
return toAppendTo;
}
#Override
public Object parseObject(String source, ParsePosition pos) {
return null; // no need to be implemented
}
});
volumeValue.set(Config.getInstance().VOLUME);
}
public void addMusicFolderTab(final String t, final ArrayList<MusicListItem> items) {
Platform.runLater(new Runnable() {
#Override
public void run() {
Tab m = new Tab("Test Tab");
musicTabs.getTabs().add(0, m);
}
});
}
}
The method addMusicFolderTab is called from a thread that is used to scan files and directories.
In the initialize method I can access the ui-elements but in the method addMusicFolderTab, that is called from the filescanner-thread, the variable musicTabs is null. Here is the exception:
java.lang.NullPointerException
at de.roth.jsona.javafx.ViewManagerFX$3.run(ViewManagerFX.java:110)
I have no clue, why I can't access the TabPane from outside the initialize method.
Aside from the many questionable patterns used here, the problem is that your ViewManagerFX singleton (besides not being a singleton) never has its instance set.
When using FXML, the Controller is created and loaded dynamically by Reflection from the FXMLoader.
What happens is that by calling ViewManagerFX.getInstance(), you access the a different controller than the one created by the FXMLoader. The instance you access is the one created here:
private static ViewManagerFX instance = new ViewManagerFX();
The quickest way to solve the issue is to set the instance in the initialize() since it's called by the FXMLoader on the instance created by the FXMLoader.
public void initialize() {
instance = this;
// Volume
...
}
I have tryed to build a Java Class in JSf witch adds a view with a Pager to an XPage
Im Using a UiDataview in this simple example but my problem is that the Pager witch is added to the result is never displayed in my Xpage. anyone an idea what i have to do?
public class MainLibcontrol extends UIComponentBase implements FacesComponent {
private static final String RENDERER_TYPE = "de.my.MainLibcontrol";
private static final String COMPONENT_FAMILY = "de.my";
public MainLibcontrol() {
setRendererType(RENDERER_TYPE);
}
#Override
public String getFamily() {
return COMPONENT_FAMILY;
}
#SuppressWarnings("unchecked")
public void initBeforeContents(FacesContext arg0) throws FacesException {
try {
UIDataView viewtable = new UIDataView();
viewtable.setColumnTitles(true);
CategoryColumn categoryColumn = new CategoryColumn();
categoryColumn.setComponent(viewtable);
categoryColumn.setColumnName("form");
categoryColumn.setColumnTitle("form");
categoryColumn.setContentType("text");
viewtable.addCategoryColumn(categoryColumn);
DominoViewData data = new DominoViewData();
data.setComponent(viewtable);
data.setViewName("142342");
data.setVar("view2");
viewtable.setData(data);
viewtable.setId("dataView1");
viewtable.setRows(3);
SummaryColumn summaryColumn = new SummaryColumn();
summaryColumn.setComponent(viewtable);
summaryColumn.setColumnName("5");
summaryColumn.setColumnTitle("5");
viewtable.setSummaryColumn(summaryColumn);
XspPager pager = new XspPager();
pager.setPartialRefresh(true);
pager.setLayout("Previous Group Next");
pager.setId("pager1");
viewtable.getChildren().add(pager);
this.getChildren().add(viewtable);
} catch (Exception e) {
e.printStackTrace();
}
}
public void buildContents(FacesContext arg0, FacesComponentBuilder arg1) throws FacesException {
.....
}
public void initAfterContents(FacesContext arg0) throws FacesException {
....
}
}
I haven't tried this out, but I would imagine you want to add it as a facet of the viewTable not as a child.
so your line should be
viewtable.getFacets().put("headerPager", pager);
