[Q] Setting up a test environment

Can anyone advise this rookie user how to set up a test environment to use with an Android Studio project?
I recently installed Android Studio on my Windows 7 laptop and put together my first simple app. When I tried to debug it, I was offered two pre-configured test environments. The first was "Nexus 5 API 21x86" but when I tried to use that one it told me I needed HAXM. After much research I worked out what I needed to do to install HAXM but the installation file gave me the following error message:
VT_Not_Support = This computer does not support Intel Virtualization Technology (VT-x). HAXM cannot be installed."
I therefore turned my attention to the second option "TestDevice". When I tried to run that, Android Studio reported:
emulator: ERROR: This AVD's configuration is missing a kernel file!!
emulator: ERROR: ANDROID_SDK_ROOT is undefined
I Googled the error and found the advice that I needed to install "ARM EABI v7a System Image" but when I ran the SDK manager it told me that this component was already installed.
Can anyone please tell me either how to overcome the ANDROID_SDK_ROOT undefined problem or advise how otherwise to set up an emulated test environment that works on my computer.
I am an experienced programmer but a complete novice when it comes to Android Studio, all the associated applications and Android devices in general.
Many thanks in advance for your patience.

Keith, have you tried enabling VT-x in your BIOS settings?

Thanks for the suggestion. I wasn't aware of this BIOS setting. I will give it a try but may not have a chance to try it out until the weekend

This should do the trick if you have compatible CPU.

Gradle Sync Error

Hello, I am trying to get android studio working on my debian computer but when I installed it every time I either try to open an existing project or start a new one I get the error "gradle sync failed: process 'command '/usr/android-studio/jro/bin/java' ' finished with non-zero exit value 2. I tried downloading the latest gradle and re-downloading android studio and neither have worked.

Hi Zachdog,
Have you found a solution yet?
I have the exact same problem, been working on it for days now.
I tried:
* for more then a few hours to find a solution online (mainly stackoverflow)
* change a AS compiler setting (heap size) as follows: Configure > Settings > Build, Execution, Deployment > Compiler> Change Build process heap size (Mbytes) to 1024 and Additional build process to VM Options to -Xmx512m
* deleted the MyFirstApp project and started over again
* read the AS idea.log
* searched more on the internet
* 'run' the app, which resulted in: "Error running build: Module 'MyFirstApp' is not backed by gradle"
* restart AS and PC
* in Project Setting > Gradle i have "use defeault Gradle wrapper (recommended)"
* in Project Structure > JDK Location i have "Use embedded JDK (recommended)"
* Re-installed android studio.

Android Studio 3.1.3: Error message 'Cannot find symbol: View'

I'm new to Android development and I just started playing with Android Studio 3.1.3. I'm following a tutorial from android.developer.com and I'm on the part: Start Another Activity - Respond to the Send button. Thing is, when I add the sendMessage() method stub, I get an error message saying the symbol View cannot be found. I tried the following steps to resolve the issue but I'm not successful:
- Place the cursor on View then click ALT-ENTER but the menu Import class doesn't appear.
- I clicked File - Invalidate Caches/Restart
Any useful assistance is welcome.

Android Studio ERROR: Unsupported method:

So Im creating my first ever app and I cant code so I used buildbox. Im trying to make my game into an apk but when i put it into Android Studio it says:
ERROR: Unsupported method: AndroidProject.getVariantNames().
The version of Gradle you connect to does not support that method.
To resolve the problem you can change/upgrade the target version of Gradle you connect to.
Alternatively, you can ignore this exception and read other information from the model.
Any help would be greatly appreciated!
