I am trying to explore Xamarin, trying to create simple CURD project.
I was able to make some progress by watching youtube video's, but I am not sure what went wrong all of the sudden I am getting blank screen in my emulator when I am trying to deploy the project.
Firstly it showed me error stating
'the targetFrameWorkVersion is greater than my project version. You
need to increase the version for the project'.
I tried it, I increased my project version. This issue got resolved but gave birth new error.
Secondly
'To deploy this application, your deployment target should be running
Windows Universal Runtime version 10.0.16299.0 or higher. You
currently are running version 10.0.14393.2007. Please update your OS,
or change your deployment target to a device with the appropriate
version.'
I looked up for newer version of OS, but it seems my OS is already up to date.
I really appreciate if anyone help me out with tips or clue.
Environment is as follows
Visual Studio: 2017
Operating System: Windows 10
I am attaching ScreenShot of error
:
Try this
Set your android project as StartUp project
In your VS menu go to Build ->Configuration Manager
Uncheck the UWP project from both Build and Deploy, i hope your issue will be sorted.
first
its not your SDK, this is cause by old nugets in your project.
update all your nugets. at least xamarin.forms.dll
second
update your windows OS to latest. then
install appropriate microsft windows mobile sdk version. the link should appear when you right click your project and select install missing features

I have tried so far every solution; clean, change the namespace etc. I still cannot get this resolved.
I have created an Android project with API 19 and it creates another project alongside mine called appcompat_7. This project has quite a few erros and one of them is " article_view cannot be resolved or is not a field ".
The following files have the errors;
ArticleFragment.java
HeadlinesFragment.java
MainActivity.java
All of these files seem to have issues with R.layout.*
I am not sure what would resolve this issue at this point as this is completely new project and I have tried almost every API above 17 and each project has definitely an error that does not get resolved with clean etc. I am using Eclipse Luna and I am sure I was able to install the correct SDK.
As a note: Am I the only one who thinks this IDE for Android is somewhat messy and not friendly at all?
Thank you for any insight.
Edit:
I solved the problem by trying API 18 for both compiler and target. It did not create the appcompat_v7 project so I just fixed the dependencies and changed the namespaces. I still think Eclipse is not working well with Android plugin.
I was also stuck with the same issue few day ago,
I resolved the same issue by updating sdk to latest version 23.0.4. and extras: Android support Repository to rev. 6 Android support Library to rev. 20
first of all open up your Android sdk Manager from eclipse and download all latest sdk updates and extra downloads.
And then after downloading all updates , you have need to use a fresh Eclips editor because your existing eclipse will not let you successfully update from Android sdk tool 20 to 21.0.4 Then just use a fresh eclips editor and set up updated android sdk path in the fresh eclips (the same one you have used in your last eclipse editor , you can find it at Window>> Prefrences >> Android).
Hopefully this will solve your problem.
I recently downloaded all the latest updates for my eclipse/Android plugins (before the upgrades everything worked fine). I got everything to work except when i try to create a new project I get a message that I need Android support library revision 8. I click Install/Upgrade and It proceeds to download and install the library. When it finishes the tiny download/install window disappears but the window which informs me that i need Android support library revision 8 remains open and i cant click finish to create new project. I tried closing the window and eclipse and trying it again but it always leads me to the window which states I need the Android support library revision 8. I didnt move eclipse to any other location and I am wondering what is wrong.
I had a problem before with an ! in my eclipse path and eclipse wouldnt work because of exit error 13. I posted a question about it before. My answer explains what has happened and the easy fix.
I am wondering what is wrong now. Do i need to manually link the support library?
Im really frustrated because its taking me forever to set this up.
Update:
I tried restarting eclipse and reinstalling the library multiple times.
I upgraded the android sdk tools and sdk platform-tools before i installed the support libraries.
Like these similar issue i'd for 2 days ago. Whenever, i'm trying to create a new project its showing me like below
For, this i've downloaded that support library using Install/Upgrade and in my path E:/Android/Android-Sdk/extras/android/compaitability I've changed the name of compaitability as support and after just restarted my Eclipse. Its working fine.
Hope these helps you.
Try updating android sdk tools and sdk platform-tools and restart eclipse? ADT has dependencies on these.
I want to install support Compability Package but my SDK Manager doesn't see it. What should i fix?
Here is my screen:

But it should be like this:

ADT version - 19. OS - Windows. I think that no problem with eclipse, because when i start SDK Manager without eclipse, thru Program Files I have the same situation.
You need to provide way way way way more information than that... what OS are you working with, what version of eclipse, which ADT revision, etc.
Honestly, I would just try a fresh install... trying to fix eclipse is a waste of time (in my experience at least). In your case, it seems like you are better off just starting from scratch.
I resolve problem by updating to the ADT version 20 . And Android Platform tools version 14.
I'm developing for Android with Eclipse, and all was working well until yesterday. I used Ninite to update all my stuff, including JREs and everything (pro tip: do not do that), and it restarted my computer without asking in the middle of editing my workspace.
This caused all kinds of filthy problems, but now it all works, except for Android. I've updated Android SDK and the eclipse ADT, then when I try to tell Eclipse the SDK location, it gives this error:
This Android SDK requires Android Developer Toolkit version 14.0.0 or
above. Current version is 12.0.0.v201106281929-138431. Please update
ADT to the latest version.
Now, this is an outright lie. My ADT is version 14.0.something. I've tried Help>Check for updates, it says there are no updates. I've tried Help>Install new software...>Available Software Sites and removing the ADT repo, then reinstalling ADT, and it says it failed because I already have version 14.0.whatever.
How do I convince eclipse that my ADT is up to date??
I found the answer to the problem. (I'm using Helios, but it should work anyway)
Goto folder /Program Files(x86)/Eclipse/Plugins/ and make sure previous older versions of com.android.ide.eclipse.adt.package_##... are deleted (sometimes update fails to delete because of UAC). Keep the current desired version and complete the following.
Run Eclipse as administrator or disable UAC temporarily. (windows 7)
Go to Help → Install New Software.
On Work with: type https://dl-ssl.google.com/android/eclipse/ and press ENTER.
Wait for Eclipse to fetch the repository. An item named Developer tools will appear in the list.
Mark it for install, press Next and follow the steps to install the ADT tools.
When finished, it will ask to restart Eclipse. Make sure you do this.
When Eclipse restarts, all your Android SDK packages should show up again.
Dont forget to resume UAC if you need it.
An option is to manually download the ADT plugin (ADT archive) required. The page is, http://developer.android.com/sdk/eclipse-adt.html. The page reveals ADT 18 is available at http://dl.google.com/android/ADT-18.0.0.zip. The link is closer to the bottom page. I needed 17 although 18 was the latest, so I modified the download URL, changing 18 to 17.
Select Help → Install New Software → Add → Choose Archive and select the location of the downloaded ADT archieve file, Choose OK.
Select the components required and proceed as required. You may get a message that the software is already installed, proceed with the installation.
Hope this helps.
I had the same problem. My ADT in the eclipse was 8.x version. But my app required version 12 or more. So, I decided to upgrade both the Android SDK and ADT to the latest (at this time latest ADT is 17). I was able to upgrade the SDK but not the ADT. It always complained I got the versions already but I only had 8.x. The new SDK that I just upgraded would function only with ADT 14 and above. So, I had successfully broken my android development!!
The reason why I wasn't able to upgrade my ADT to the latest was because I was using Eclipse 3.5. The newer ADT versions require 3.6 or above. This small but key bit of information was really at the bottom of the error generated by Eclipse which required scrolling down (since only the top few lines of error were displayed). You typically wouldn't scroll down since these top few lines were followed by whitespace lines :). I did not scroll and I guess I wasted about a day trying to rectify this problem. But eventually I saw those 2 up/down arrows at the right of the dialog box and I scrolled down. There it clearly mentioned ADT 17 requires Eclipse runtime 3.6 and over.
So my solution was to find a suitable ADT that would work with Eclipse 3.5. Yes, tomorrow when I am in the mood, I shall upgrade to Eclipse 3.6 or 3.7 and the boat load of plugins I have :)
I've just upgraded my Android SDK version, and had exactly the same issue.
The 'Check For updates' Eclipse command failed because, for some reasons, Android Traceview failed to update.
My solution was to :
* Open Eclipse → Help → About Eclipse .
* Click Installation Details.
* Here select all the android related lines, and update them one by one, restarting eclipse each time.
And finally it worked ( even with Helios ) !
Best option is go to open eclipse ID
Then go to Help → About Eclipse >>
u will find the Installation Details button click on that
And now u can see the all anriod extension installed.
Select all or select one by one and just click the update button.
you will get the latest version from the net.
Hope these will help you all.
In Eclipse:
Help → Check for Updates.
Your ADT and SDK is not up-to-date yet and Eclipse is complaining about the right stuff...
Open Android SDK Manager from toolbar and update your SDK from there. It doesn't help if you are checking Eclipse updates. Because through Eclipse you cannot check SDK updates for Android.
Button looks like this :
I'm hearing a common issue is that newer Android ADK versions require newer eclipse versions. Colleagues who hit this say they installed Indigo in place of older Helios versions and were able to resolve the issue this way. I have not yet done the same myself.
To anyone else with this problem, my solution was just to delete the Eclipse folder, and download a new copy from scratch. I had to then re-download all plugins including adt, which worked this time round.
