Can not create AVD in Lollipop android-5 - android

I have installed Android API version 21 (lollipop), since i have been trying to set up an AVD . There is no "new" button,instead there is a "Create" option . then no matter what configuration i set , AVD manager fails to create the emulator.I have checked for updates.No issue with OK button . I tried a lot of things ... Any clue ??

Android 5.0 Lollipop has not been released by far. But it will be at 12th Nov at America time zone. So, the IDE downloaded from Android Developer site is the preview version. And, I tried it as you, but, I realized it was incomplete. And some features were unavailable. So, I have been waiting for the release version, Android 5.0 Lollipop and its IDE bundled with ADT and Eclipse. Hopefully, this will help.

Android 12 - Emulator (Xamarin.Android )

I have been trying to find some reliable solution to this but I couldn't. I have added Android 11 - S which is an Android 12 Beta image in Android SDKs as shown in the following screenshot
But when I go and try to create the Emulator device in Device Manager I don't see this API in the list
What Am I doing wrong here?
Final release planned for early 2022.
In Visual Studio you can find Android 12 here:
From document Android 12 Preview, we find that :
The Android 12 Preview program runs from February 2021 until the final
public release to AOSP and OEMs, planned for later in the year. At key
development milestones, we'll deliver updates for your development and
testing environments. Each includes SDK tools, system images,
emulators, API reference, and API diffs.
Since it's still in beta, there's definitely some instability, so for that reason, it's still not released. We need to wait patiently for the final release.
In VS2022 17.0.5, Android 12 is available as a choice in the emulators list. However, be warned. Debugging/deploying android Xamarin in VS 2022 as of this version is sloowwwwww. Anyone with any leads on that, please hit me up!

Visual Studio 2015 Unsupported Devices

I have a new set up visual studio 2015 (updated) in a new laptop and I am having a problem with my project from an old laptop. I don't know why my device and 2 emulators are listed on Unsupported Devices in this new set up visual studio.
Minimum Android version is set to android 4.1 jelly bean
target is set to compile using SDK version
Compile using nougat 7.0/also tried to marshmallow 6.0
I have my phone nougat 7.0 and 2 emulators 6.0 but I don't know why from my copied project from old laptop says API Level is less than the minimum Android version defined in the manifest file
Already tried to delete bin and obj folders. Tried to set min, target and compile with other combinations but no luck to solve this issue.
What can I do with this old project in my new VS 2015 set up? My new projects don't have a problem at all.
I ran into the same problem, there's a "minimun android version" dropdown under the Android Manifest tab in the project settings. Changing it there made my emulator pop up again. Got the idea by reading this: https://developer.xamarin.com/guides/android/application_fundamentals/understanding_android_api_levels/
Edit: I'm using Visual Studio 2017 Community
I found the answer for this. I have found out that it is because of API 24 and up from my SDK manager. I deleted those API and voila ! Unsupported devices are gone and back to normal . I don't know if it is because of the project built from another laptop only having API 23 below and when I transferred it to a my laptop with Nougat and Oreo API, unsupported devices happened. Hope it give helps to other coders.

In eclipse I a getting the API level 20 .I want ot use lower versions of API

How to change API level. when selecting this API level it shows no CPU/ABi available and also I am not able to add text fields it throws an exception.
Image 1Image 2
In Eclipse go to manifest.xml
<uses-sdk android:minSdkVersion="int" />
In android studio: go to your app Gradle there you can find the minSdkVersion. Lower it to the version you needed.
android {
....
defaultConfig {
....
minSdkVersion 17
....
}
}
Quick Fix: Uncheck installed checkbox to see other downloads and try to refresh android sdk manager, restart it or restart the computer. API 19 worked fine for me before I moved to android studio.
I'm not sure if API 20 is supported in eclipse, I recommend Android Studio for android development. Anyway, if you have an old PC that does not meet android studio minimum requirement, download IntelliJ IDEA https://www.jetbrains.com/idea/, it's a bit lighter and free and require 1 GB of RAM (But 1 GB is very bad, you need at least 2 GB without running android emulator). However, if you still want to work with eclipse I think you need API 19 you have to download it manually from the web and move it to android SDK location. Or you can install android studio to download SDK without using it.
Newer APIs are way better, they have more libraries that supports both old and new android versions. It's really worth upgrading to Android Studio.
For the CPU/ABi error check this post Android 4.3 Virtual Device CPU/ABI - No system images installed (eclipse)

Android Studio SDK is not compatible with Windows

I've installed Android Studio in Windows 10. When I open Android SDK Manager and try to install 2.2 SDK platform I have the problem. It's not compatible with Windows and I can't install it. I've attached a screen shot of the problem. I can't install any version below 4.0 (API 14).
Allright I had the same problem but managed to fix it (I believe)
Found a website that has standalone downloads for each version
If you download them and place them into the android-sdk/platforms folder named as "android-APINUMBER" for example version 2.1 would be "android-7" then you reload the manager and they will show as installed, hope that helps and also I hope they make them downloadable again.
The api level 8 is very old and according to the api distribution the distribution of api level 8 is 0.1%. Most of the libraries and apps comes today on play store will be targeting newer devices so there is no meaning of supporting devices with api level 8. So it is advisable to target newer devices and newer apis which have more features.
It's not just 2.2 flagged as not compatible with Windows.
I had same problem. To solve it I clicked on Packages at top and clicked Show Obsolete Packages which then enables you to download/install the package
The fix is to run SDK Manager.exe in Administrator mode. You need to run it manually from the android\sdk directory. This clears the issue.
I had the same issue, but I have resolved it the next:
1) Install jdk1.8...
2) In AndroidStudio File->Project Structure->SDK Location, select your directory where the JKD is located, by default Studio uses embedded JDK but for some reason it produces error=216.
3) Click Ok.
Today, I encountered the same problem.
Later, I found that a security software takes up virtualization.
My solution is to turn off the use of security software for virtualization.
Turn off!

Android Studio Robotium Recorder Plugin Compatibility issue

I have Android API Levels 15,19,20,21 and Android Studio 1.0.1.
Robotium Recorder needs API 15 or higher version. Information about Robotium API support
I follow that guide from Robotium's page
and also I tried many things like those (all following steps were tested separately from each other);
I created emulators that's API level 15 and 19, Than I tried to start Robotium,It did not work.
I connected my Android phone which is API level 19,that did not work again.
I started Android Studio with administrator permission everytime.
I downloaded robotium.jar here It did not work.
I tried every method in my mind.
My minimum sdk version and target sdk version is also 19.
But when I clicked "New Robotium Test" button, immediately appears warning text that is "Please install a compatible Android API level (15 or higher)"
There is a screenshot about problem. Any advice?
You probably have two Android SDK:s installed in your computer. If you go to settings (on the left side of "New Robotium Test") you can change the SDK to be used by Robotium Recorder.
