i've a problem using ParseObject.saveAllInBackground on my android app
List<ParseObject> objList = new ArrayList<ParseObject>();
for(ParseObject object : myobjectsbeendet)
{
ParseObject obj = ParseObject.createWithoutData("games", object.getObjectId());
object.put("playershow", "0");
//object.saveInBackground();
objList.add(obj);
}
progress.show();
ParseObject.saveAllInBackground(objList, new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Toast.makeText(getApplicationContext(), "saved", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), e.getMessage().toString(), Toast.LENGTH_LONG).show();
}
progress.dismiss();
}
});
i've already queried all objects and saved them to a static variable (myobjectsbeendet). now i want to change the value "playershow" to "0" --> nothing happens if i use saveAllInBackground. if i uncomment the line
//object.saveInBackground(); and save the data for each object in the for loop all works fine... not using saveAllInBackground
thanks!
I found the answer......
I was using:
object.put("playershow", "0");
instead of:
obj.put("playershow", "0");

I'm using camera2basic, when I change flash parameter on runtime it not working and load first parameter when app loading.
example : when I set auto-flash in hardcode it worked when I change it to Off in my app it not work and flash parameter is auto-flash yet.
I want to set flash parameter in application not hardcode. How can i do it?
**//Camera2BasicFragment.cs**
public void CaptureStillPicture()
{
try
{
var activity = Activity;
if (null == activity || null == mCameraDevice)
{
return;
}
// This is the CaptureRequest.Builder that we use to take a picture.
if (stillCaptureBuilder == null)
stillCaptureBuilder = mCameraDevice.CreateCaptureRequest(CameraTemplate.StillCapture);
stillCaptureBuilder.AddTarget(mImageReader.Surface);
SetFlash(stillCaptureBuilder);
// Orientation
int rotation = (int)activity.WindowManager.DefaultDisplay.Rotation;
stillCaptureBuilder.Set(CaptureRequest.JpegOrientation, GetOrientation(rotation));
mCaptureSession.StopRepeating();
mCaptureSession.Capture(stillCaptureBuilder.Build(), new CameraCaptureStillPictureSessionCallback(this), null);
}
catch (CameraAccessException e)
{
e.PrintStackTrace();
}
}
ControlAEMode AeFlashMode = ControlAEMode.Off;
public void SetFlash(CaptureRequest.Builder requestBuilder)
{
if (mFlashSupported)
{
requestBuilder.Set(CaptureRequest.ControlAeMode, (int)AeFlashMode);
}
}
-------------------------------
**//CameraCaptureSessionCallback.cs**
public override void OnConfigured(CameraCaptureSession session)
{
// The camera is already closed
if (null == owner.mCameraDevice)
{
return;
}
// When the session is ready, we start displaying the preview.
owner.mCaptureSession = session;
try
{
// Auto focus should be continuous for camera preview.
owner.SetFocus(owner.mPreviewRequestBuilder);
// Flash is automatically enabled when necessary.
owner.SetFlash(owner.mPreviewRequestBuilder);
// Finally, we start displaying the camera preview.
owner.mPreviewRequest = owner.mPreviewRequestBuilder.Build();
owner.mCaptureSession.SetRepeatingRequest(owner.mPreviewRequest,
owner.mCaptureCallback, owner.mBackgroundHandler);
}
catch (CameraAccessException e)
{
e.PrintStackTrace();
}
}
You can add following code to your CameraCaptureSessionCallback.cs
public void ISFlashOpenOrClose(bool isTorchOn)
{
owner.mCaptureSession = this.session;
if (isTorchOn)
{
owner.mPreviewRequestBuilder.Set(CaptureRequest.FlashMode, (int)ControlAEMode.On);
// owner.mPreviewRequestBuilder.Set(CaptureRequest.FlashMode, (int)FlashMode.Off);
// mPreviewSession.SetRepeatingRequest(mPreviewBuilder.build(), null, null);
owner.mPreviewRequest = owner.mPreviewRequestBuilder.Build();
owner.mCaptureSession.SetRepeatingRequest(owner.mPreviewRequest,
owner.mCaptureCallback, owner.mBackgroundHandler);
// isTorchOn = false;
}
else
{
owner.mPreviewRequestBuilder.Set(CaptureRequest.ControlAeMode, (int)ControlAEMode.Off);
owner.mPreviewRequest = owner.mPreviewRequestBuilder.Build();
owner.mCaptureSession.SetRepeatingRequest(owner.mPreviewRequest,
owner.mCaptureCallback, owner.mBackgroundHandler);
}
}
Here is all of code about CameraCaptureSessionCallback.cs
public class CameraCaptureSessionCallback : CameraCaptureSession.StateCallback
{
private readonly Camera2BasicFragment owner;
CameraCaptureSession session;
public CameraCaptureSessionCallback(Camera2BasicFragment owner)
{
if (owner == null)
throw new System.ArgumentNullException("owner");
this.owner = owner;
}
public override void OnConfigureFailed(CameraCaptureSession session)
{
owner.ShowToast("Failed");
}
private bool isTorchOn;
public override void OnConfigured(CameraCaptureSession session)
{
// The camera is already closed
if (null == owner.mCameraDevice)
{
return;
}
this.session = session;
// When the session is ready, we start displaying the preview.
owner.mCaptureSession = session;
try
{
// Auto focus should be continuous for camera preview.
owner.mPreviewRequestBuilder.Set(CaptureRequest.ControlAfMode, (int)ControlAFMode.ContinuousPicture);
// Flash is automatically enabled when necessary.
owner.SetAutoFlash(owner.mPreviewRequestBuilder);
// Flash is automatically enabled when necessary.
// owner.SetFlash(owner.mPreviewRequestBuilder);
// Finally, we start displaying the camera preview.
owner.mPreviewRequest = owner.mPreviewRequestBuilder.Build();
owner.mCaptureSession.SetRepeatingRequest(owner.mPreviewRequest,
owner.mCaptureCallback, owner.mBackgroundHandler);
}
catch (CameraAccessException e)
{
e.PrintStackTrace();
}
}
public void ISFlashOpenOrClose(bool isTorchOn)
{
owner.mCaptureSession = this.session;
if (isTorchOn)
{
owner.mPreviewRequestBuilder.Set(CaptureRequest.FlashMode, (int)ControlAEMode.On);
// owner.mPreviewRequestBuilder.Set(CaptureRequest.FlashMode, (int)FlashMode.Off);
// mPreviewSession.SetRepeatingRequest(mPreviewBuilder.build(), null, null);
owner.mPreviewRequest = owner.mPreviewRequestBuilder.Build();
owner.mCaptureSession.SetRepeatingRequest(owner.mPreviewRequest,
owner.mCaptureCallback, owner.mBackgroundHandler);
// isTorchOn = false;
}
else
{
owner.mPreviewRequestBuilder.Set(CaptureRequest.ControlAeMode, (int)ControlAEMode.Off);
owner.mPreviewRequest = owner.mPreviewRequestBuilder.Build();
owner.mCaptureSession.SetRepeatingRequest(owner.mPreviewRequest,
owner.mCaptureCallback, owner.mBackgroundHandler);
}
}
}
}
You can change it by ISFlashOpenOrClose method at runtime.
we have implement file chooser for web view. it works successfully when attachment is selected, but fails when cancelled without file specification. The file chooser just stops to react on click
any help is appreciated. Thanks
we use chrome client. it works fine if in all cases, file selection is listed. but even from the first file selection is cancelled, no longer file chooser will work. It is Xamarin.Android app based fully on webview
Our code is:
protected override void OnActivityResult(int requestCode, Result resultCode, Intent intent)
{
if (requestCode == FILECHOOSER_RESULTCODE)
{
if (null == _mUploadMessage)
return;
// Check that the response is a good one
if (resultCode == Result.Ok)
{
Android.Net.Uri[] results = null;
if (intent == null)
{
// If there is not data, then we may have taken a photo
if (mCameraPhotoPath != null)
{
results = new Android.Net.Uri[] { Android.Net.Uri.Parse(mCameraPhotoPath) };
}
}
else
{
if (intent.DataString != null)
{
results = new Android.Net.Uri[] { Android.Net.Uri.Parse(intent.DataString) };
}
}
_mUploadMessage.OnReceiveValue(results);
_mUploadMessage = null;
}
}
}
Chrome client:
var chrome = new FileChooserWebChromeClient((uploadMsg) =>
{
_mUploadMessage = uploadMsg;
mCameraPhotoPath = null;
Intent takePictureIntent = new Intent(Android.Provider.MediaStore.ActionImageCapture);
//Create the File where the photo should go
File photoFile = null;
try
{
string folder = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
photoFile = new File(folder, "image" + DateTime.Now.Millisecond + ".png");
takePictureIntent.PutExtra("PhotoPath", mCameraPhotoPath);
}
catch (IOException ex)
{
// Error occurred while creating the File
System.Console.WriteLine("" + ex.ToString());
}
// Continue only if the File was successfully created
if (photoFile != null)
{
mCameraPhotoPath = "file:" + photoFile.AbsolutePath;
takePictureIntent.PutExtra(Android.Provider.MediaStore.ExtraOutput,
Android.Net.Uri.FromFile(photoFile));
}
else
{
takePictureIntent = null;
}
Intent contentSelectionIntent = new Intent(Intent.ActionGetContent);
contentSelectionIntent.AddCategory(Intent.CategoryOpenable);
contentSelectionIntent.SetType("image/*");
Intent[] intentArray;
if (takePictureIntent != null)
{
intentArray = new Intent[] { takePictureIntent };
}
else
{
intentArray = new Intent[0];
}
Intent chooserIntent = new Intent(Intent.ActionChooser);
chooserIntent.PutExtra(Intent.ExtraIntent, contentSelectionIntent);
chooserIntent.PutExtra(Intent.ExtraTitle, this.GetStringFromResource(Resource.String.chose_photo));
chooserIntent.PutExtra(Intent.ExtraInitialIntents, intentArray);
base.StartActivityForResult(chooserIntent, HarmonyAndroid.AndroidMainActivity.FILECHOOSER_RESULTCODE);
});
return chrome;
Part 2
class FileChooserWebChromeClient : WebChromeClient
{
Action<IValueCallback> callback;
public FileChooserWebChromeClient(Action<IValueCallback> callback)
{
this.callback = callback;
}
public override bool OnShowFileChooser(WebView webView, IValueCallback filePathCallback, FileChooserParams fileChooserParams)
{
callback(filePathCallback);
return true;
}
public override void OnCloseWindow(WebView window)
{
base.OnCloseWindow(window);
}
}
Part 3
webView.ImprovePerformance();
webView.SetWebViewClient(new HomeWebViewClient(customWebViewClientListener, clientId));
webView.SetWebChromeClient(chrome);
webView.Settings.JavaScriptEnabled = true;
webView.Settings.DomStorageEnabled = true;
webView.SetDownloadListener(new CustomDownloadListener(activity, customDownloadListener));
webView.AddJavascriptInterface(new JavaScriptToCSharpCommunication(activity, javaScriptToCSharpCommunicationListener), Constants.JS_CSHARP_COMMUNICATOR_NAME);
Try to give a null object to the uri callback, when the resultCode is not RESULT_OK.
add in your OnActivityResult method:
if (resultCode != Result.Ok)
{
_mUploadMessage.OnReceiveValue(null);
_mUploadMessage = null;
return;
}
For retrieve location i have used GoogleAPIClient with FusedLocationProvider API.
These functions are in onCreate() method.
createLocationRequest();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
gpsChecker();
Full Code
protected void createLocationRequest() {
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(INTERVAL);
mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
public void gpsChecker() {
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true);
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
#Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can initialize location
// requests here.
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(
AddVisitActivity.this, 1000);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way to fix the
// settings so we won't show the dialog.
break;
}
}
});
}
For run time permissions i did this.
protected void startLocationUpdates() {
if (ActivityCompat.shouldShowRequestPermissionRationale
(AddVisitActivity.this, android.Manifest.permission.ACCESS_FINE_LOCATION)) {
Snackbar.make(findViewById(android.R.id.content),
"Please Grant Permissions",
Snackbar.LENGTH_INDEFINITE).setAction("ENABLE",
new View.OnClickListener() {
#Override
public void onClick(View v) {
if (ActivityCompat.checkSelfPermission(AddVisitActivity.this, android.Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(AddVisitActivity.this,
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_CODE_LOCATION);
} else {
LocationServices.FusedLocationApi.requestLocationUpdates(
mGoogleApiClient, mLocationRequest, AddVisitActivity.this);
Log.d(TAG, "Location update started ...: ");
}
}
}).show();
} else {
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_CODE_LOCATION);
} else {
LocationServices.FusedLocationApi.requestLocationUpdates(
mGoogleApiClient, mLocationRequest, this);
Log.d(TAG, "Location update started ...: ");
}
}
}
For checking if the GPS enabled or not in setting screen using gpsChecker() with request code 1000 and in onActivityResult() i have done this.
if (requestCode == 1000) {
switch (resultCode) {
case Activity.RESULT_OK:
Log.i(TAG, "User agreed to make required location settings changes.");
startLocationUpdates();
break;
case Activity.RESULT_CANCELED:
Log.i(TAG, "User chose not to make required location settings changes.");
finish();
break;
}
}
While i execute this code in some devices its working and in some device the location request automatically set to Device Only or Battery Saving though i have set mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
Note : Mi Note 4, Vivo V9 Pro, Mi Note 5 Pro and some other device getting the issue
So what should i need to change in my code so will it work proper with the High Accuracy?
Finally solved by changing
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
to
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
and change
private static final long INTERVAL = 1000 * 60 * 60;
private static final long FASTEST_INTERVAL = 1000 * 5;
interval time to 30 minutes and fastest interval to 5 seconds means once get location in 5 seconds after then new location will be get in 30 minutes.
Try this solutin with GPS Provider and make sure that your GPS service is ON.
static final int LOCATION_INTERVAL = 1000;
static final float LOCATION_DISTANCE = 10f;
//put this in onCreate();
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

return;
}
Location location = locationManager.getLastKnownLocation(mprovider);
locationManager.requestLocationUpdates(mprovider, LOCATION_INTERVAL, LOCATION_DISTANCE, this);
if (location != null)
onLocationChanged(location);
else
Toast.makeText(getBaseContext(), "No Location Provider Found Check Your Code", Toast.LENGTH_SHORT).show();
}
//put this LocationListener after onCreate();
public LocationListener mLocationListener = new LocationListener() {
#Override

if (location != null) {
Log.e(String.format("%f, %f", location.getLatitude(), location.getLongitude()), "");

How to retain the saved isolatedstoragesettings while at application launch
I used exception for termination on backevents :
protected void _BackKeyPress(object sender, CancelEventArgs e)
{
if (MessageBox.Show("Do you want to close the application?", "Q", MessageBoxButton.OKCancel) != MessageBoxResult.OK)
{
e.Cancel = true;
System.IO.IsolatedStorage.IsolatedStorageSettings.ApplicationSettings.Add("key2", "33r4 ");
}
else
{
if (IsolatedStorageSettings.ApplicationSettings.Contains("Key"))
{
IsolatedStorageSettings.ApplicationSettings["Key"] = App.Current.ViewModel;
}
else
{
IsolatedStorageSettings.ApplicationSettings.Add("Key", App.Current.ViewModel);
}
throw new Exception("ExitApplication");
}
}
I try to save the viewmodel which declares in app.xaml.cs, but cant able to get the isolatedstorage settings value in it, at launch. But It compiles and run successfully.
You need to call the IsolatedStorageSettings.Save method:
protected void _BackKeyPress(object sender, CancelEventArgs e)
{
if (MessageBox.Show("Do you want to close the application?", "Q", MessageBoxButton.OKCancel) != MessageBoxResult.OK)
{
e.Cancel = true;
System.IO.IsolatedStorage.IsolatedStorageSettings.ApplicationSettings.Add("key2", "33r4 ");
IsolatedStorageSettings.Save();
}
else
{
if (IsolatedStorageSettings.ApplicationSettings.Contains("Key"))
{
IsolatedStorageSettings.ApplicationSettings["Key"] = App.Current.ViewModel;
}
else
{
IsolatedStorageSettings.ApplicationSettings.Add("Key", App.Current.ViewModel);
}
IsolatedStorageSettings.Save();
throw new Exception("ExitApplication");
}
}
Hello I have no idea where I should start looking. I add few prop (before that my code run fine), then I get
System.Diagnostics.Debugger.Break();
so then I comment that changes, but that didn't help.
Could you suggest me where I should start looking for solution?

Running stop at that line.
// Code to execute if a navigation fails
private void RootFrame_NavigationFailed(object sender, NavigationFailedEventArgs e)
{
if (System.Diagnostics.Debugger.IsAttached)
{
// A navigation has failed; break into the debugger
System.Diagnostics.Debugger.Break();
}
}
You should check all of the URLs you have both in the XAML and code. When you get to the NavigationFailed function, it means that the phone tried to navigate to some page that did not existed. We would be able to help more if you could tell what were you doing when the app threw the exception.
System.Diagnostics.Debugger.Break();
usually happens because of an Uncaught Exception.
Either post the code which started giving problems, or the stack trace when you encounter this problem.
No one can tell anything without actually seeing what you are doing.
