I'm using Android UX SDK 4.13 with MAVIC_2_ENTERPRISE.
My goal is to access the FPV stream via the TextureView.
Im failing to find the id of the FPVwidget that is required by the following line:
TextureView videostreamPreviewTtView = (TextureView)findViewById(R.id.XXX);
In the UXSDK this is the activity layout:
<dji.ux.widget.FPVWidget
android:layout_width="match_parent" android:layout_height="match_parent"/>
I tried to add Id in the activity but the setSurfaceTextureListener did not invoked the onSurfaceTextureAvailable.
How can I get reference to the FPV widget?
I solved the problem by adding the id to the UX-SDK layout:
<dji.ux.widget.FPVWidget
android:id="#+id/FPVWidgetObj"
android:layout_width="match_parent"
android:layout_height="match_parent" />
With the new id I managed to gain access to the object:
TextureView videostreamPreviewTtView = (TextureView)findViewById(R.id.FPVWidgetObh);
The actual bitmap was retrieved with the following command:
Bitmap bitmap = videostreamPreviewTtView.getBitmap();

Hi Am working on google maps. i have added location in a fragment now am trying to add StreetViewPanoramaView to the fragment . But am getting Oops! something went wrong error message as shown in 2nd image
this is my code
maps_activity.xml
<Button
android:id="#+id/button_streetview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Open StreetView"
/>
<androidx.fragment.app.FragmentContainerView
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context=".MapsActivity" />
<com.google.android.gms.maps.StreetViewPanoramaView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/streetview"/>
This is my MapActivity.kt
button_streetview.setOnClickListener(View.OnClickListener {
var mStreetViewPanoramaView : StreetViewPanoramaView = findViewById(R.id.streetview)
mStreetViewPanoramaView.onCreate(savedInstanceState)
var streetViewPanorama: StreetViewPanoramaOptions = StreetViewPanoramaOptions()
streetViewPanorama.panningGesturesEnabled(false)
streetViewPanorama.position(address)
streetViewPanorama.userNavigationEnabled(false)
streetViewPanorama.zoomGesturesEnabled(true)
var streetViewPanoramaCamera : StreetViewPanoramaCamera = StreetViewPanoramaCamera(25F,30F,1F)
streetViewPanorama.panoramaCamera(streetViewPanoramaCamera)
mStreetViewPanoramaView = StreetViewPanoramaView(this,streetViewPanorama)
mStreetViewPanoramaView.getStreetViewPanoramaAsync(this)
})
i can successfully retrive latitude and longitude of a place by address and display it in infoWindow and add custom marker as shown in image.
But when i click openstreetview button error message is coming.
This is the StreetView
This is the logcat
As This Error message is showing Wrong API key but i have added correct Key as i can retrive and display a marker successfully. Can anyone please tell me where am doing wrong
It looks like you are getting the error described here:
If you receive an error such as Your card does not support automatic
recurring payments or General decline of the card, please select a
different form of payment.
You might encounter these errors if you are using a debit card that
requires two-factor authentication to complete an online transaction.
Two-factor authentication requires you to be in-session at the time of
the transaction. Cards that require you to be in-session are not
usable for subscriptions or similar recurring automatic transactions.
Your street view map should work without problem once you enable billing on your project. Hope this helps!
I want to show VR tour like this http://alfavr.ir/alfavr.ir/to/park.html in my Android app.
how can I do that?
I tried to display with web view because the file format is Html but did not work.
You can try with VRPanormaView which is included in the Google VR SDK. This is an example from https://developers.google.com/vr/develop/android/vrview:
<com.google.vr.sdk.widgets.pano.VrPanoramaView
android:id="#+id/pano_view"
android:layout_margin="5dip"
android:layout_width="match_parent"
android:scrollbars="#null"
android:layout_height="250dip" />
Inside the Activity, the primary method is VrPanoramaView.loadImageFromBitmap(). Call it with a standard Android Bitmap object and an optional VrPanoramaView.Options object. The latter is used to configure the format of the image. The Activity also implements a VrPanoramaEventListener which receives events when the load operation succeeds or fails.
Adding this line make It work.
webView.getSettings().setJavaScriptEnabled(true);
The app is running on Android 6 or below. But when running on Android 7 (Nougat) it throws runtime exception.
System.InvalidCastException: Unable to convert instance of type 'Android.Widget.LinearLayout' to type 'Android.Support.V7.Widget.Toolbar'.
The error is thrown in Xamarin (Visual studio 2017) at below code:
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
protected override void OnCreate(Bundle bundle)
{
ToolbarResource = Resource.Layout.toolbar;
TabLayoutResource = Resource.Layout.tabs;
base.OnCreate(bundle); //Runtime error here
.... Other code ...
}
}
I've taken latest updates for All Nuget packages but not able to identify the issue. For testing I'm using Moto G4+ (Android 7.0).
Can anybody help please?
Edit 1:
Layout of toolbar is as : (Under resources > layout > toolbar.axml). This was already there when App version with Android 6 released. But Now visited app back for Android 7 issues.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
I solved this by just cleaning the entire solution and closing the emulator. Then deploy again and it should work.
I tried Señor Hernandez's answer without much success, then realized I had accidentally deleted Resources/Resource.designer.cs from my Android project. I had meant to delete it from disk only, expecting it to get regenerated on rebuild. It did get regenerated, but that did not add it back to the project. Doing so (right-click, include in project) solved the issue on my part.
It got solved by downloading android_m2repository_r29.zip repository from https://developer.xamarin.com/guides/android/troubleshooting/resolving-library-installation-errors/ with instruction given in same.
I also tested the issue by creating a new fresh solution and got some style "Resource not found error". That was also fixed and then the original problem also got fixed.
You get this kind of error when trying to assign a control (a UI element in your xml) on a variable that is not of the same type. I get this error frequently when I make a mess and try to assign an EditText to a TextView variable or vice versa, i. e
EditText myText = FindViewById<TextView>(Resource.Id.myText);
or
TextView myText = FindViewById<EditText>(Resource.Id.myText);
I'm pretty sure that in your case you are trying to assign an Android.Widget.LinearLayout to a variable of type Android.Support.V7.Widget.Toolbar.
I think in your case one of this variables have been defined as LinearLayout in your xml:
Resource.Layout.toolbar
Resource.Layout.tabs
Meanwhile, one of this variables have beeen defined as Toolbar in your C# code, so te cast is not possible:
ToolbarResource
TabLayoutResource
If the problem persist, you can also try to check the type Android.Support.V7.Widget.Toolbar, instead it could be Android.Widget.Toolbar in your xml or code.
I have an existing Android Cordova project which uses an embedded WebView. What this means is that the Activity does not extend CordovaActivity, but instead embeds the SystemWebView and initializes within the onCreate.
The following is currently how this is being done:
Within the layout XML file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
.... other layout elements not related to Cordova....
<org.apache.cordova.engine.SystemWebView
android:id="#+id/cdvWebView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
Within the Activity's onCreate:
SystemWebView systemWebView = (SystemWebView) findViewById(R.id.cdvWebView);
CordovaWebView cdvWebView = new CordovaWebViewImpl(new SystemWebViewEngine(systemWebView));
ConfigXmlParser parser = new ConfigXmlParser();
parser.parse(this);
cdvWebView.init(this, parser.getPluginEntries(), parser.getPreferences());
Due to the bug in Lollipop versions 5.0.+ missing the "set" button, I want to implement the Crosswalk plugin into the project.
Unfortunately, all the documentation I'm finding assumes that a typical Cordova install is being used. I haven't been able to get the embedding and initialization of the XWalkWebView working correctly and keep getting a blank white screen.
Has anybody has success with a similar scenario?
I'm not sure, but this might answer your question. It seems to show implementing an XWalkWebView outside of a typical cordova project:
https://github.com/kurli/crosswalk-website/wiki/How-to-use-Crosswalk-Embedded-API-on-Android
In Android project I'm trying to add databindings using CrossLight part of MvvmCross.
Bindings to standard TextView/Buttons work great. But simplest markup with Mvx.Control:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android">
<Mvx.MvxListView />
</LinearLayout>
Gives an error
"Binary XML file line #1: Error inflating class Mvx.MvxListView"
The same thing is with Mvx.Spinner.
However, when instantiating it from code in Activity.OnCreate:
_bindingContext = new MvxAndroidBindingContext(this, new LayoutInflaterProvider(LayoutInflater), _viewModel);
var view = (LinearLayout)_bindingContext.BindingInflate(Resource.Layout.Main, null);
SetContentView(view);
var spinner = new MvxSpinner(this, null, new MvxAdapter(this, _bindingContext));
view.AddView(spinner);
Everything works great (including bindings). What am I doing wrong? Is this scenario supported in general?
Or maybe I should reference anything else except nuget MvvmCross.HotTuna.CrossCore?
P.S. Haven't found any samples with custom controls and CrossLight neither on github, nor on N+1 videos
If you want to use namespace abbreviations within your non-MvvmCross application, then you'll need to add those abbreviations. This can be done using a custom binding builder or using a 'light' setup step like:
var viewResolver = Mvx.Resolve<IMvxAxmlNameViewTypeResolver>();
viewResolver.ViewNamespaceAbbreviations["Mvx"] = "Cirrious.MvvmCross.Binding.Droid.Views";
viewResolver.ViewNamespaceAbbreviations["MyApp"] = "MyApp.Controls";
When doing this within a full MvvmCross application, then you can override the Setup property ViewNamespaceAbbreviations
protected override IDictionary<string, string> ViewNamespaceAbbreviations
{
get
{
var toReturn = base.ViewNamespaceAbbreviations;
toReturn["MyApp"] = "MyApp.UI.Droid.Controls";
return toReturn;
}
}
When markup was changed to using the full namespace and layout_width and layout_height attribute was added it started to work!
<Cirrious.MvvmCross.Binding.Droid.Views.MvxSpinner
android:id="#+id/MySpinner"
android:layout_width="fill_parent"
android:layout_height="20dp"
/>
It was found when I switched to default Android inflater and it was complaining about missing layout_width in Exceptions.
