问题 Our company is developing Android app in Xamarin.Forms (3.5.0) framework. Since now all users were able to update application from Google Play store without problems. After new update some of them got Google Play error "Can't install app". Like this one https://i.ytimg.com/vi/XOAgJz2vQu4/hqdefault.jpg but without error code. This problem occurs only for some users (about 80% users already updated to newest version). They already tried deleting Google Play cache and other solutions to this

问题 I need the Java class's name in the Constructor for Android.Content.ComponentName as Xamarin doesn't have an overloaded constructor that takes typeof(ClrType) like it does for some other things. 回答1: I was able to solve it by doing this: Java.Lang.Class.FromType(typeof(MyClass)).Name 来源： https://stackoverflow.com/questions/37413519/xamarin-android-how-to-get-java-class-name-for-passing-into-componentname

问题 What's the proper way to translate raw touch points to screen coordinates in MonoTouch or MonoDroid? My code works well on the emulator but the points are inaccurate on a device. Here's what I have so far: private void Initialize() { this.Touch += TouchView_Touch; } void TouchView_Touch(object sender, View.TouchEventArgs e) { e.ReturnValue = true; touchPoints.Add(e.Event.RawX); touchPoints.Add(e.Event.RawY); this.Invalidate(); } protected override void OnDraw(Android.Graphics.Canvas canvas) {
