The problem occurs with all projects (i.e. the new ones and the downloaded samples). This started happening only since last two days. Probably, after I updated the fuse tools to the latest version. Also, I applied the latest patch for android studio 2.1.\*(just fyi, in case it matters). Current fuse version on my machine: **Fuse version 0.12.4 (build 6406)** On running with **fuse build --target=Android --run -v** , here’s the output: ```auto Uno 0.27.19 (build 2575) Windows 10 x86 125974c Configuring Project file: fp1.unoproj Search paths: C:\Program Files (x86)\Fuse\Packages, C:\ProgramData\Uno\Packages Packages: UnoCore (0.27.22), Uno.Collections (0.27.3), ObjC (0.27.2), Experimental.iOS (0.27.2), Uno.Geometry (0.27.3), Uno.Threading (0.27.22), Uno.Net.Sockets (0.27.3), Fuse.Designer (0.27.16), FuseCore (0.27.16), Experimental.Physics (0.27.16), Fuse.Animations (0.27.16), Fuse.Drawing (0.27.16), Fuse.Drawing.Batching (0.27.16), Fuse.Drawing.Meshes (0.27.16), Fuse.Drawing.Planar (0.27.16), Android (0.27.4), Experimental.TextureLoader (0.27.3), Uno.Net.Http (0.27.22), Experimental.Http (0.27.16), Fuse.Scripting (0.27.16), Fuse.Triggers (0.27.16), Fuse.Elements (0.27.16), Fuse.Drawing.Primitives (0.27.16), Fuse.Drawing.Polygons (0.27.16), Fuse.Drawing.Paths (0.27.16), Fuse.Entities (0.27.16), Fuse.Gestures (0.27.16), Fuse.Navigation (0.27.16), Uno.Data.Json (0.27.3), Uno.Testing (0.27.22), Fuse.Camera (0.27.16), Fuse.GeoLocation (0.27.16), Fuse.Launcher (0.27.16), Fuse.Scripting.Duktape (0.27.16), Fuse.Scripting.JavaScriptCore (0.27.16), Fuse.Scripting.Jurassic (0.27.16), Fuse.Scripting.V8 (0.27.16), Fuse.Storage (0.27.16), Fuse.UserEvents (0.27.16), Fuse.Vibration (0.27.16), Fuse.Reactive (0.27.16), Fuse.Shapes (0.27.16), Fuse.Controls (0.27.16), Fuse.Effects (0.27.16), Fuse.Physics (0.27.16), Fuse.BasicTheme (0.27.16), Fuse.Video (0.27.16), Fuse.Themes (0.27.16), Fuse.Android (0.27.16), Fuse.Desktop (0.27.16), Fuse.iOS (0.27.16), fp1 (0.0.0) Output dir: build\Android\Debug (13,506.84 ms) Compiling syntax tree (29,461.71 ms) Generating code and data 309 namespaces stripped. 5082 types stripped. 47323 fields stripped. 102102 functions stripped. 582 classes sealed. 1104 functions sealed. * 195 functions stripped from vtable.

Same here, Most of the projects seems not working in Android. They should also focus on Android platform like in iPhone. ---

Hey folks, sorry that you’ve been hit by this, it is rather odd as it looks like the support lib is being copied to the build folder. You can check this by looking in `/app/src/main/libs` and seeing if you have the `android-support-v4.jar` there. We have seen issues with the support library before though, which is odd as our scripts just call the default tools to download these. If any of you could try the following and report back here whether it fixed the issue we would be super grateful. - Open the terminal/command-line - run `uno android sdk`. This should open the android SDK Manager that Fuse is using - Click the `Deselect All` link at the bottom of the SDK Manager. - Click the `Updates` link just above the `Deselect All` link - Check to see if the `Android Support Library` is marked for update. If it hasn’t been install please let us know and check the tick-box next to `Android Support Library` - Click the `Install _ packages` button. - Once the install is complete run a `clean` and then `build` your project Fuse project again. Once again sorry this is happening, up until now we have seen this in very rare circumstances so any data you folks can provide will be immensely useful ---

Uninstalling the support library, and then re-installing it using the fuse SDK manager ( **_uno android sdk_** ) did the trick for me. The build now succeeds. ---

Thanks so much for following up on this. Glad to hear it is working. @Anyone-Else-With-This-Issue: Please post a “Me too” comment below. It will really help us get a feel for who is getting hit by this. It is really unsatisfying to us that we can’t roll out a real fix to all of you, we are holding out that somehow there is something we can do to mitigate this. Feel free to throw ideas at us! ---

Library updated through “uno android sdk” and working like a charm!
