问题 I was testing our app using test cases from Facebook's developers site. https://developers.facebook.com/docs/facebook-login/testing-your-login-flow Our app failed two following test cases: Someone removes your app from Facebook via app settings and revisits your app. Your app should detect this and prompt the person to log back in. Go to your app and tap on the "Log in with Facebook” button Tap OK to accept the read permissions (and OK again to accept write permissions where applicable) Go to

问题 The Play Store now allows you to specify credentials for the Pre-launch Report emulator to use. In order for the emulators to know which text field to add the credentials to and which button to click to login, it asks for the text field and button's Resource Name. Do any of the Xamarin Form's properties translate into a Resource name? I tried looking in the /obj/ and /bin/ folders after building my app to see if one of the files had anything like this but I did not find anything. Possible

问题 An app I'm designing uses the VpnService, along with the VpnService.Builder, classes to generate a VPN in order to block traffic from specific apps. According to the documentation over at developer.android.com, all apps should be allowed through the VPN until Builder.AddAllowedApplication or Builder.AddDisallowedApplication is called. When my VPN service starts up, for some reason, all apps are being disallowed which is strange. As soon as I disconnect from the VPN, all apps become available

问题 So I just implemented FCM in my Xamarin.Forms Android app with this guide. Everything works pretty well, the notifications arrive, they play a sound, have an icon etc. Then I wanted to add an action to my notification, it has to open a certain page in my app. And thats were my problem comes in, Xamarin.Forms puts all Android content in a single Activity. Which means that opening a certain page causes the whole OnCreate of the MainActivity to load again (And the LoadApplication as well). My

问题 I'm working on a simple xamarin android app, that allows to display a responsive web site, and receive push notifications. Webview seems to have some limitations on Xamarin, so I used the following workaround (https://github.com/GabLeRoux/xamarin-android-webview-upload) based on the following comments (https://forums.xamarin.com/discussion/3259/cannot-override-webviewclient-class-for-file-upload-support) in order to get html upload button work as expected. Everything goes well, until I

问题 I currently have a android:TextView which is bound to a string which may or may not contain HTML. <TextView android:text="Medium Text" android:textAppearance="?android:attr/textAppearanceMedium" android:layout_width="fill_parent" android:layout_height="wrap_content" android:autoLink="all" android:padding="10dp" style="@style/ListItemText" local:MvxBind="Text Answer" /> Somehow I need to be able to display this text with the html rendered. So I thought I would switch the TextView to a WebView

问题 I watched Google IO 2011 conference, read almost every post about OutOfMemory Exception and InflateException, no luck, I cannot find any answer that solve my problem. How can I properly clear memory from a layout containing a background image? I feel like if the InflateException followed by OutOfMemory are related because that background image is not cleared properly. So I'm getting : Android.Views.InflateException: Binary XML file line #24: Error inflating class followed by : Java.Lang

问题 I am using for C# in Xamarin to create an android app. I have created an extension of the scrollview. Here is my code for that public class EndlessScroll : ScrollView { public EndlessScroll (Context context) : base (context) { } public EndlessScroll(Context context, IAttributeSet attrs) : base(context, attrs) { } public EndlessScroll(Context context, IAttributeSet attrs, int defStyle) : base(context, attrs, defStyle) { } public interface OnScrollViewListener { void onScrollChanged

问题 We are developing a cross platform app on a PCL, but for the time being we are only using android devices for testing. Our concern is that its taking about 6 to 8 seconds (depending on which device we test it) to start the app, which is very slow. After placing a few breakpoints we saw that the timing is consumed pretty evenly. We did notice this particular parts took longer: 1s before reaching onCreate() on MainActivity (there's a splash screen before which only has one image and a
