I am not able to receive notification on android device. I am seeing following error message on app startup.
Could not find method android.database.Cursor.getNotificationUri, referenced from method com.parse.ParseSQLiteCursor.getNotificationUri
Any pointers?
If your code was similar to old code in parse sample code like above.
// Specify an Activity to handle all pushes by default.
PushService.setDefaultPushCallback(this, SavedVideoListActivity.class);
ParseInstallation.getCurrentInstallation().saveInBackground();
Try to choose this code in new sample code. (https://parse.com/tutorials/android-push-notifications)
ParsePush.subscribeInBackground("", new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Log.d("com.parse.push", "successfully subscribed to the broadcast channel.");
} else {
Log.e("com.parse.push", "failed to subscribe for push", e);
}
}
});

I have a app in xamarin that listen a folder and do some action when a file is created.
But the thing is that I need to be able to :
bring my app in front when a file is created
push my app in rear when acyion are finished
I have a beginning of response with
Window.Current.Activate();
but that only work if my app is not minimize (app not in first view)
I've already tried this :
IList<AppDiagnosticInfo> infos = await AppDiagnosticInfo.RequestInfoForAppAsync();
IList<AppResourceGroupInfo> resourceInfos = infos[0].GetResourceGroups();
await resourceInfos[0].StartSuspendAsync();
but visual studio tell me
AppResourceGroupInfo don't have a definition for StartSuspendAsync()
but documentation mention it AppResourceGroupInfo.StartSuspendAsync Method
someone have an idea ?
UPDATE [2020-04-29 16:48] :
This is a pcl project
the intention is to use dependency service to have diferent comportement in function of platform (already implemented just need the front/rear
interface in pcl
public interface IWindowManager
{
void Minimize();
void Maximize();
}
in uwp
class WindowManager : IWindowManager
{
public async void Maximize()
{
try
{
Window.Current.Activate();
}
catch(Exception ex)
{
DependencyService.Get<IErrorLogger>().LogError(ex);
}
}
public async void Minimize()
{
IList<AppDiagnosticInfo> infos = await AppDiagnosticInfo.RequestInfoForAppAsync();
IList<AppResourceGroupInfo> resourceInfos = infos[0].GetResourceGroups();
resourceInfos[0].StartSuspendAsync();
}
}
and as I say StartSuspendAsync() encounter some problem
AppResourceGroupInfo don't have a definition for StartSuspendAsync()
Derive from official document, StartSuspendAsync() available in the Windows 10 update 1803 (build 17134). So please edit the UWP project mini version to 17134.
but that only work if my app is not minimize (app not in first view)
For making the app foreground, you could use the following code.
IEnumerable<AppListEntry> appListEntries = await Package.Current.GetAppListEntriesAsync();
await appListEntries.First().LaunchAsync();
Update
If above does not work, please try use register a protocol for UWP app and launch it with Windows.System.Launcher.LaunchUriAsync method.
public async void Maximize()
{
try
{
await Windows.System.Launcher.LaunchUriAsync(new Uri("testapp:"));
}
catch (Exception ex)
{
Debug.Write(ex);
}
}
I am using Android Studio 3
I am following this article to learn how to use Google Recaptcha in Android Studio.
Installed the package using this: implementation 'com.google.android.gms:play-services-safetynet:12.0.1'
API keys are also registered.
I saw there is onClick event handler but where is it mentioned about rendering the recaptcha?
Update 1
When I wrote the button click code as mentioned in the link...I got a complication error: inconvertible types cannot cast anonymous android.view.view.onclicklistener to java.util.concurrent.executor
Code as asked in comment
btn_Login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View view) {
SafetyNet.getClient(this).verifyWithRecaptcha("")
.addOnSuccessListener((Executor) this,
new OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse>() {
#Override
public void onSuccess(SafetyNetApi.RecaptchaTokenResponse response) {
// Indicates communication with reCAPTCHA service was
// successful.
String userResponseToken = response.getTokenResult();
if (!userResponseToken.isEmpty()) {
// Validate the user response token using the
// reCAPTCHA siteverify API.
}
}
})
.addOnFailureListener((Executor) this, new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
if (e instanceof ApiException) {
// An error occurred when communicating with the
// reCAPTCHA service. Refer to the status code to
// handle the error appropriately.
ApiException apiException = (ApiException) e;
int statusCode = apiException.getStatusCode();
} else {
}
}
});
}
});
I used below code and everything is work fine now.
Make sure to implement Executor in the activity
btn_Login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View view) {
SafetyNet.getClient(Activity.this).verifyWithRecaptcha("")
.addOnSuccessListener((Activity) MyActivity.this,
new OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse>() {
#Override
public void onSuccess(SafetyNetApi.RecaptchaTokenResponse response) {
// Indicates communication with reCAPTCHA service was
// successful.
String userResponseToken = response.getTokenResult();
if (!userResponseToken.isEmpty()) {
// Validate the user response token using the
// reCAPTCHA siteverify API.
}
}
})
.addOnFailureListener((Activity) MyActivity.this, new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
if (e instanceof ApiException) {
// An error occurred when communicating with the
// reCAPTCHA service. Refer to the status code to
// handle the error appropriately.
ApiException apiException = (ApiException) e;
int statusCode = apiException.getStatusCode();
} else {
}
}
});
}
});
According to the article, in your button click handler you must call the method SafetyNet.getClient(this).verifyWithRecaptcha(...) to show reCAPTCHA and handle success or error. Passing this, you give the SDK handle to your current view which should be shown after solving reCAPTCHA. Most probably the rendering will be done by the SDK itself given that it’s a part of the OS. And most probably it will be full-screen in a separate top-level view blocking access to your app before solving the riddle.
You should try to implement it in your app as described in the article and see how it goes. Then you can ask a more specific question.
EDIT: You combined 2 techniques in your code: copy-pasting the code from Google and implementing anonymous class from it. So the problem you asked in the comment is that using (Executor) this in line 5 refers now not to your View (as it was there in the original tutorial) but to the instance of the anonymous interface implementation new View.OnClickListener() that you created. Ypu can refer to this answer to see how it can be implemented not interfering with already complex reCAPTCHA code.
I'm using Xamarin.Forms and have this method to fetch my user object
public static async Task<Object> GetCurrentUser()
{
try
{
return await BlobCache.UserAccount.GetObject<Object>("NewUser").FirstOrDefaultAsync();
}
catch (KeyNotFoundException)
{
return null;
}
}
The code works well on my iOS emulator but keeps crashing on the android with this error
System.Collections.Generic.KeyNotFoundException The given key 'NewUser'
was not present in the cache.
Please I need help
I'm writing a Chromecast receiver to play different kind of contents (including embedded flash videos). I'd like to use my own JS library to create the player canvas, not to rely on the html video element.
I'm currently blocked because I can't get a media to be loaded using a custom behaviour :
Receiver :
Nothing fancy in the HTML, I just load my library in the #mediaWrapper div. Then I create a MediaManager from it.
var node = $( "#mediaWrapper" )[0];
var phiEngine = new phi.media.Player( node );
window.mediaManager = new cast.receiver.MediaManager( phiEngine );
window.castReceiverManager = cast.receiver.CastReceiverManager.getInstance();
/* Override Load method */
window.mediaManager['origOnLoad'] = window.mediaManager.onLoad;
window.mediaManager.onLoad = function (event) {
console.log('### Application Load ', event);
/* Custom code (load lib, set metadata, create canvas ...) */
window.mediaManager.sendLoadComplete(); // Doesn't seem to do anything
// window.mediaManager['origOnLoad'](event);
// -> Fails 'Load metadata error' since url is not a video stream
// -> ex: youtube url
}
/* Will never be called */
window.mediaManager['origOnMetadataLoaded'] = window.mediaManager.onMetadataLoaded;
window.mediaManager.onMetadataLoaded = function (event) {
...
}
Sender :
I use my own android application to cast to the device. I can't use the Companion library because it will be a Titanium module.
private void createMediaPlayer() {
// Create a Remote Media Player
mRemoteMediaPlayer = new RemoteMediaPlayer();
mRemoteMediaPlayer.setOnStatusUpdatedListener(
new RemoteMediaPlayer.OnStatusUpdatedListener() {
#Override
public void onStatusUpdated() {
Log.e(TAG, "onStatusUpdated");
}
}
});
mRemoteMediaPlayer.setOnMetadataUpdatedListener(
new RemoteMediaPlayer.OnMetadataUpdatedListener() {
#Override
public void onMetadataUpdated() {
Log.e(TAG, "onMetadataUpdated");
}
});
try {
Cast.CastApi.setMessageReceivedCallbacks(mApiClient,
mRemoteMediaPlayer.getNamespace(), mRemoteMediaPlayer);
} catch (IOException e) {
Log.e(TAG, "Exception while creating media channel", e);
}
mRemoteMediaPlayer
.requestStatus(mApiClient)
.setResultCallback(
new ResultCallback<RemoteMediaPlayer.MediaChannelResult>() {
#Override
public void onResult(MediaChannelResult result) {
Log.e(TAG, "Request status : ", result.toString());
if (!result.getStatus().isSuccess()) {
Log.e(TAG, "Failed to request status.");
}
}
});
}
private void loadMedia( MediaInfo mediaInfo, Boolean autoplay ) {
try {
mRemoteMediaPlayer.load(mApiClient, mediaInfo, autoplay)
.setResultCallback(new ResultCallback<RemoteMediaPlayer.MediaChannelResult>() {
#Override
public void onResult(MediaChannelResult result) {
Log.e(TAG, "loadMedia ResultCallback reached");
if (result.getStatus().isSuccess()) {
Log.e(TAG, "Media loaded successfully");
} else {
Log.e(TAG, "Error loading Media : " + result.getStatus().getStatusCode() );
}
}
});
} catch (Exception e) {
Log.e(TAG, "Problem opening media during loading", e);
}
}
Expected behaviour :
I basically first call createMediaPlayer() once, then call loadMedia(...). The first call to loadMedia will show nothing in the log : nor success or fail. Next calls issue with errorCode 4.
I get the load event on the receiver side. But, back to the sender side, I can't manage to end the load phase and get a media session to be created.
I was expecting sendLoadComplete() to do so but I might be wrong. How can I have the media status to update and the loadMedia ResultCallback to be reached ?
My goal is to use RemoteMediaPlayer.play(), pause(), ... but for now I get stuck with 'No current media session' because the media isn't loaded yet.
Also, I'd really enjoy to be able to log any message the Sender receives, before being processed. Is it possible ?
Hope I did not forget any information,
Thanks for your help !
edit: I solved this by using a custom message channel since it seems that I can't use RemoteMediaPlayer the way I want to.
I believe the error code 4 you are receiving is bogus; see https://plus.google.com/u/0/+JimRenkel2014/posts/aY5RP7X3QhA . As noted there, I created a Chromecast issue for this (https://code.google.com/p/google-cast-sdk/issues/detail?id=305&thanks=305&ts=1403833532). Additional support for this issue will help it get fixed faster! :-)
.sendLoadComplete(true)
The boolean value helped me to receive the loaded event on sender. Might help you as well.
I want to close my app if network not available.
I check network in App.cs:
private void Application_Launching(object sender, LaunchingEventArgs e)
{
if (!NetworkInterface.GetIsNetworkAvailable())
{
//close my app
}
else
{
//continue to work
}
}
Is there a better way to do it?
Thanks in advance.
just add reference to Microsoft.Xna.Framework.Game i'm sure you can achieve exit with this code and it will be ok. if you wanna show message box you have to do it in main page
what i would do:
protected override void OnNavigatedTo(NavigationEventArgs e)
{
if (!NetworkInterface.GetIsNetworkAvailable())
{
MessageBoxResult m = MessageBox.Show(Sorry, no internet connection is available.do you want to exit the application , "Oops...", MessageBoxButton.OKCancel);
if (m == MessageBoxResult.OK)
{
var g = new Microsoft.Xna.Framework.Game();
g.Exit();
}
}
}
you should provide a "gentle" way for closing
5.1.2 - App closure
The app must handle exceptions raised by the any of the managed or native System API
and not close unexpectedly. During the certification process, the app is monitored
for unexpected closure. An app that closes unexpectedly fails certification. The app
must continue to run and remain responsive to user input after the exception is
handled.
