I'm new in the Xamarin Development world so I installed Visual Studio 2017 with all the needed cross compiler features.
After downloading and updating the SDKs for Android API 23, 24, 25 and 26 and some corresponding emulator images I got the emulators starting up.
I created a base Xamarin Android App within VS, compiled and deployed it to the simulator.
By deploying/installing the generated APK to the simulator I get the following error:
Failure [INSTALL_FAILED_INVALID_APK: Package couldn't be installed in /data/app/BlankAndroid.BlankAndroid-1: Package /data/app/BlankAndroid.BlankAndroid-1/base.apk code is missing]
It doesn't matter which SDK I choose as “Target Framework” or which Simulator I choose (Android 6, Android 7 or 7.1). The result is the same: The apk is not installed, but the “Mono Shared Runtime” are present and will be updated.
I figured out that the created apk file does not contain a file “classes.dex” or any oder dex files just some ressources. A file “classes.zip” in the directory “obj\Debug\android\bin\classes” with the generated java classes out of my C# is present. These files should be compiled with the DEX-Compiler to the classes.dex file, when I understood correctly.
Even other sample projects from the Internet have exactly the same result.
What do I do wrong?
The problem got solved by fresh installing the Android SDK and all related components. It seemed to have a SDK missmatch between an old Google Android SDK and the new installed Xamarin Android SDK.
I faced the same problem and tried many solutions from the search in web but this one to an extent solved that deploy failure issue.
In the emulator, open settings -> Apps -> Uninstall your app if it is listed
Deploy the app from visual studio again.
This solved the problem that said base.apk is missing.
Try setting your project back to the current recommended defaults. Remove all of the following properties from the .csproj file:
AndroidEnableMultiDex
AndroidDexGenerator
AndroidLinkTool
AndroidDexTool
This will let Xamarin.Android pick the current latest default values, this apply for Visual Studio for Mac and VS 2017-2019

I am trying to install an old Xcode project built-in Xcode 8.8.2. But unfortunately, whenever I am trying to install project it's showing some errors.
So, the project is an old Origami studio (built by Facebook). Currently, we are trying to install into an old macOS El Capitan, under Xcode 8.8.2.
Also, I am new to Xcode development. So, I may need step by step assistance to resolve the issue.
Thanks
Origami Studio projects can only be opened through Origami Studio. Origami Studio doesn't export code that can be used in native build processes and the files cannot be opened properly in a code editor.
I just installed Android Studios and trying to build my first app. When I press play on the emulator the message "unable to locate adb" pop-up. How to solve this problem?
I had this problem when updating to Android Studio 4.0.
I even tried uninstalling (and doing a full cleanup) Android Studio and installing again. The problem persisted.
The problem was that when importing my old project, the new Android Studio couldn't find the SDK and my project had no SDK (even though it could build, go figure).
So check File -> Project Structure -> Project. In my case there was a big red NO SDK set there. Once I set the SDK to the one installed, problem was solved.
I guess you didn't set the system and user environment path in your windows.
Goto properties of This PC > Advanced System Settings > Environment Variables > Path > then put the path file location.

I am aiming to deploy a mobile application to the iOS platform using codes developed in Visual Studio for an Android phone. I am unable to open the Visual Studio file on my Macbook (macOS High Sierra ver.10.13.6) as Visual Studio here does not seem to support .jsproj files. As such, I have attempted following the instructions in the link below to run a remotebuild on my mac while debugging codes and seeing an iOS simulator on my Windows computer.
https://learn.microsoft.com/en-us/visualstudio/cross-platform/tools-for-cordova/first-steps/ios-guide?view=toolsforcordova-2017#run-on-simulator
I was able to get the remotebuild running, however, I came across the error where it required my projects to use cordova-ios 4.3.0 or greater with Xcode 8.3. As my windows computer does not have Xcode, I turned to my macbook and tried updating and adding the Cordova iOS platform through the terminal, where it said "Current working directory is not a Cordova-based project." I have searched the error up and it said that it required my Visual Studio project to be open, which I am unable to do so as my file is not supported in the Mac version of Visual Studio.
The iOS version in my Windows Visual Studio is currently 4.2.0 and I am unsure how to get about updating it. I have seen the link below but in only applies to Macbook, where I cannot open the Visual Studio project file.
Install specific version of Cordova CLI in Visual Studio 2017
I have installed node.js as well as Git, also attempting to include/update the Cordova iOS platform through the command prompt (Once again unsure if that was the method, but I tried), however, the command prompt did not recognise the update to cordova. Under the toolset in Visual Studio, I have tried ticking on the checkbox under Cordova platforms to take the latest patch, where ~4.2.0 appears, but still does not update.
I am still new to coding and things seem very foreign to me, if I have missed out anything vital or am doing something fatally wrong, please do enlighten me.
I'm trying to build a blank cordova application into my iPad Air 2 with Visual Studio 2015 Enterprise edition as i've already done it with success with the release candidate version.
I've got node.js v 4.2.2 on both machines since version 5.2.0 was hanging the build indefinitely, i've also got latest version of iTunes (12.3.1) as well as iOS 9.2 on the mobile device.
I've got the remote MAC set up and everything works fine for the building part, infact i've checked and the .ipa file is there at the end of the build into the folder ...\Documents\Visual Studio 2015\Projects\BlankCordovaApp1\BlankCordovaApp1\bin\iOS\Debug and if i launch that it will correctly install into iTunes and the iPad itself.
The problem is that the build action with Configuration "iOS" and "Local Device" with the iPad connected to the windows 7 PC will hang indefinitely after copying back said .ipa file after writing this line into the Build Output:
2>------ Deploy started: Project: BlankCordovaApp1, Configuration: Debug iOS ------
No matter how much time i wait it wont start the debug session even if i authorized the pc onto the iPad and have my web Inspector turned on onto the safari options. At this point i have to interrupt the build to be able to work again.
What really gets me is that if i connect the iPad to the MAC machine and build with "Remote Device" option the build works fine and i can debug remotely from my windows pc, unfortunately working like that isn't an option since the Apple machine isn't in the same room of my developing machine.
Any insight about this issue would be really appreciate, thanks in advance.
You are using a recent version of node and thus will also need to use a recent version of Cordova.
Specifically, you need to use Cordova 5.3.3 to be able to use Node.js 4.x.x+. The hang you are experiencing is exactly why. It's an incompatibility with a down stream node module and Node 4.x.x. You can downgrade to Node 0.12.x or upgrade your Cordova project to 5.3.3.
http://cordova.apache.org/news/2015/09/22/tools-release.html
Note that Node 5.x.x is only supported in Cordova 5.4.1.
This should be addressed in the latest VS Tools for Cordova Update 6. Deploying to local device is now available.
Take a look at http://microsoft.github.io/vstacoblog/2016/02/04/announcing-update-6.html.
After I upgraded Titanium Studio to 3.2, whenever I build a project with SDK v. 3.2.0.GA the underlying XCode project is built from the start. This is a real pain as I have added external libraries on the XCode project and they get lost each time.
On previous versions, Studio was not doing a full rebuild so it was not even necessary to compile the project.All that was needed was to do changes, go to the emulator close the app and then reopen it.
Trying to install a pre-3.2 sdk version causes the following error Titanium SDK 3.2 [ERROR] : Invalid "--ios-version" value "7.0" 7.0.3
Could it be a flag or something else on the Studio preferences that I am missing?
Try to clean the project first (or just remove the "build" folder) and have the latest titanium cli (npm install -g titanium).
In case you have a custom Info.plist in your project try to build the proyect without it. If it works, then is something with it.
