I have downloaded latest Android Studio 2.2.3 and I want to start with C examples for project Tango phone (Lenovo Phab 2 Pro) using C API. The phone itself says it's run Android 6.0.1, kernel 3.10.84 on device.
Google developer documentation for Tango Project suggest to install Android Studio with Android SDK 24.4.1, Platform tools 23.1 and NDK 11.0.0.
By installing latest Android Studio there is no offering to install those versions of tools. Is it possible to use whatever SDK for development (latest)?
Where do I find aforementioned versions?
What Android SDK & NDK version is required for phone which run Android 6.0.1?
I started using the Dev Kit which runs Android 4.4 KitKat and I just recently got the Phab 2 Pro this week and I didn't need to make any updates to my Android Studio SDK manager.
Since I am working only with the Tango and not with the underlying Android features, I have found no need to require 6.0 for I am not using any of the extra features.
Also go here and clone the repo and run the hello-world and see if you can get it to work on your phone, if so you are good to go!
the SDK Manager which is part of Android Studio offers you choices on levels of android builds like 4.4.2/5.1/6.0/6.1, etc. Platform tools package is a module within the SDK Manager which also has levels which are based on the android build. The NDK is a completely different package and depending on what you want to accomplish you might be able to not worry about it to start of with. install Android Studio and then setup the SDK Manager to cover what devices you want to build for. get the latest Platform tools package setup and you will be ready to code. once you start setting up your environment things will fall in place. for the most part the installer does the work. pay attention to the things needed prior to installing Android Studio. i think you need to install a jdk and set paths and variables.

I am hoping to work with Xamarin for a project, primarily to learn a little about cross-platform app development, and would prefer to stick to developing on Linux. This led me to attempt to work with the JetBrains Rider IDE, something that I believed to be fairly well documented, as per these resources:
Xamarin.Android on Linux (in coordination with its Ubuntu 19.04 update post)
Failed to load Xamarin Forms project with .NET Standard 2.0 Lib in Rider
0xFireball's Xamarin.Android on Linux guide with associated Rider/IDE setup
I've been able to install everything just fine, Android Studio and Rider were installed via JetBrains Toolbox (I also tried installing Rider manually, but it made no change), and I am able to create the project and configure the Android settings for the Xamarin project.
This is where my luck ends, since despite trying the various resources I've linked above, including reinstalling mono and dotnet-sdk multiple times, I get this error no matter what I try:
Xamarin SDK was not found: Rider was unable to find Xamarin SDK on
this machine. Xamarin-based projects will not be loaded. Please
install Xamarin SDK or change toolset.
I've tried following the instructions both on a manually installed Rider 2019.1.3 (Build #RD-191.7141.460) and Rider 2019.2 EAP (Build #RD-192.5895.291).
I'm fairly new to the world of Xamarin, so I'm not sure where to begin looking. What exactly is the Xamarin SDK (is it just Xamarin.Android?), and what should I be checking my setup for in order for Rider to detect the Xamarin SDK?
It appears that what Rider installs via its Environment page, is only the Xamarin Android package. Not the actually Android Studio SDK, which is needed to develop any android apps. You have to download that separately.
We are using Unity 2018.3.8f1.
We have added Android Build Support from Unity Hub - Add Component:
But if we go to Unity Preferences - External Tools, the Android SDK location is empty:
I have not been able to find the location of the Android SDK folder anywhere. I'm wondering if the component installed by Unity Hub is something different to Android SDK. Maybe it must be installed separately from: https://developer.android.com/studio?pkg=tools#downloads?
UPDATE
So far I have installed "Command line tools only" from the previous link. Then, I have installed OpenSDK (Vistual Studio did it for me: it asked me to update and install it as one of the things to update).
But when I opened tools/bin/sdkmanager, it said "Java is not installed". So I also installed Oracle Java SDK. Unfortunately tools/bin/sdkmanager returned errors after it. I applied a few workarounds I found by googling the errors. Still not luck.
So I have moved to the easy way: installing the full version of Android Studio. If we choose custom, we'll see that Android SDK Platform is going to be installed:
So it is working, but I still have not idea of how many things I have duplicated on my system wasting space. I have:
The Android component installed from Unity Hub
Android Studio installed, which comes with the emulator and the IDE (I don't need them)
OpenSDK (installed by Visual Studio)
An embedded version of Java in Unity
Oracle Java
Are they all actually needed? I don't think so!
It seems the only thing you are wondering is if the component installed by Unity hub is something different to Android SDK... the short answer is yes. You have to download it on the Android Developer SDK website you linked in the question. You only need the SDK under "Command line tools only" at the bottom of the page. If you do this you also need to download the jdk separatly here.
I was having trouble using the Android emulator in Visual Studio Community 2017 and I decided to create a blank project to see if it will run. I get this error message when attempting to run it in the Live Xamarin Player:
Starting Android Emulator Android_Accelerated_x86_Nougat...
Failed to boot Android device emulator-5554...
Unable to deploy to Android_Accelerated_x86_Nougat, please ensure the Xamarin
Live Player app is open and the device is on the same network as Visual Studio.
Why would I have trouble running the emulator in a fresh blank project when I didn't even write a single line of code? Thanks for your help.
UPDATE: So I installed the latest Android SDK 8.0 along with they system image and tried to create a virtual device that uses it. But the Android Virtual Device Manager shows a, 'No system images installed' message when I selected the 8.0 framework. So I installed an earlier version of the SDK along with a system image (5) and was able to create a virtual device with it. So another question is why wouldn't the system images show up for the 8.0 framework?
The $(TargetFrameworkVersion) for Xamarin.Forms.Platform.Android.dll
(vv8.0) is greater than the $(TargetFrameworkVersion) for your project
(v7.1). You need to increase the $(TargetFrameworkVersion) for your
project
This means the Xamarin.Forms library is targeting Android 8.0 (API level 26) but your project is setup for Android 7.1 (API level 25). You can't change the Xamarin.Forms target version without downgrading, but you can change your project target version easily. You can learn more about these concepts from Xamarin. Be aware some of the details of that Xamarin blog post are already out of date!
There is another nice blog post from Xamarin which can walk you through the process of setting your system up for Android 8.0 API level 26. It's normally not this complicated, but Google changed their SDK tools internally between 25 and 26 in very major ways. They changed from GUI tools to command line tools.
You'll probably also want to get the (in preview) Xamarin Android Device Manager if you don't have a physical device to test with. This Xamarin Android Device Manager tool is the only way to create and configure API 26 and higher emulators without using the Google command line tools.
It seems as though Google has gotten rid of the GUI apps that manage the SDK and Virtual Devices in the latest version, so when you try to create a new virtual device with 8.0 it's not compatible with the GUI tools. Until Xamarin releases a GUI tool to replace them we can use the command-line to manage the SDK and virtual devices.

I installed nativescript from https://docs.nativescript.org/start/quick-setup page, and when I checked tns doctor I get this error:
I could search for the errors and probably learn a thing or two about the errors, but what I don't understand is why the installer itself didn't install Android SDK 22, or the other issues. I gave it full permission and it installed the sdk and other everything.
You need to android sdk 23 AND the sdk of your choice (ie 25). I would recommend using the installer instead of the cmd install line as it is a lot easier to use, which can be found here. If you use the installer, it installs the versions you need and changes the environment variables for you as well as the other parts it needs.
EDIT
Another thing to mention is that even though the installer changes the paths for you and installs the sdks, you still need to make your own emulator image. It's not hard to setup but unfortunately the nativescript installer doesnt do that for you
First up, install Android Studio
https://developer.android.com/studio
Install android API level 25 (Nougat), from the SDK Manager.
Also, setup a virtual device, if you want to run apps on emulator.
That should setup all necessary environment variables for building Android apps with nativescript.
According to the result of tns doctor, you have to install Android SDK.
You can simply install Andriod Studio. Start up Android studio, and use the built-in SDK manager to install required SDK, choose the correct version(>=23 <= 26) which was indicated in the result of tns doctor.
Alternatively, you can install Android SDK standalone, download it from Android developer site and extract files in your system, then follow the instruction of tns doctor, go to Android SDK folder, and find sdkmanager, and start up it to install required SDK with correct version.
Set ANDROID_HOME environment variable, the location points to the Android SDK folder, eg. E:\Users\hantsy\AppData\Local\Android\Sdk
Finally, try to run tns doctor again to check if all conditions are satisfied.
You can run the packaged Android app in one of the following:
Android SDK built-in simulator
A real Android mobile device
Genymotion Android simulator, more productive than SDK built-in one
Using Visual Studio 2017 and Xamarin, I installed the Xamarin Android SDK Manager to replace the default Android SDK Manager, which is now deprecated.
Then I updated JDK to the current x64 version and, using the Xamarin SDK Manager, I installed the most recent version of Android NDK.
I now want to update the locations of these SDK's in the Xamarin Android SDK Manager, Locations tab like so:
Yet, every time I restart the tool, the locations are reset. It also keeps telling me there's 2 components to install, yet when I do, it doesn't complain about any failure.
I have tried running as Admin and cannot seem to figure out what is wrong. Log files seem to be non existent. Is there anyone who has the same problem and found a solution?
This was a bug and has been fixed in 0.1.76.
