General issue in Android Studio - Cannot launch AVD in emulator.

Hello,
I could not find an answer on how to preload the expected libaries so I hope anyone can help me here.
I am a complete noob In devloping with Android Studio.
I tried to write a small app and ran it with the following errors while loading th e AVD (Android 5.1 , WVGA):
Code:
Cannot launch AVD in emulator.
Output:
libGL error: unable to load driver: i915_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i915
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
X Error of failed request: GLXBadContext
Major opcode of failed request: 155 (GLX)
Minor opcode of failed request: 6 (X_GLXIsDirect)
Serial number of failed request: 49
Current serial number in output stream: 48
emulator: ERROR: virtual device name contains invalid characters
emulator: could not find virtual device named '3.2_QVGA_(ADP2)_API_22'
I think to get this solved will not be quiet diffcult for advanced users.
Thank you verry much for your help! :good:

Error:(45, 33) Gradle: error: package com.google.android.gms.ads does not exist

I am working on android studio and have installed Google Repository alongside the Play Services. I have already tried many solutions but none of them seem to work for me. I have this line in my build.gradle file under dependencies of Android:
compile "com.google.android.gms: play-services-ads:10.2.6"
I am trying to import MobileAds in my Main class:
import com.google.android.gms.ads.MobileAds;
But it gives me the error: error: package com.google.android.gms.ads does not exist. Where am I going wrong?
My build.gradle file: pastebin.com/DmnjCrwK

try using "compile 'com.google.firebase:firebase-ads:10.2.6'" in your gradle file

A problem occurred configuring project

I am trying to compile some C++ source files into a native library using Android studio, NDK and Cmake, but upon building, I get the error:
Code:
A problem occurred configuring project ':mobile'.
> C:\Users\User\Documents\B3d\mobile\.externalNativeBuild\cmake\debug\armeabi-v7a\compile_commands.json
I went to the folder mentioned in the error and 'compile_commands.json' does not exist there. What could be the problem?
After upgrading gradle plugin, I get the error:
Code:
C:\Users\User\Documents\B3d\mobile\CMakeLists.txt : C/C++ debug|armeabi-v7a : Could not get version from cmake.dir path '"C:\Android\android-sdk\cmake\3.19.0"'.
I removed the quotes from cmake.dir path in local.properties and this error was gone, next I got another error:
Code:
exception while building Json $C:\Users\User\Documents\B3d\tv\.cxx\cmake\debug\armeabi-v7a\compile_commands.json (The system cannot find the file specified)

Android Studio 4.1.1 has built- in compilation failures

I have installed the latest Android Studio onto a new machine, and have installed Flutter plugin into the new installation. I then created a Flutter project, taking all the default settings.
After creating the project, I set up an emulator and tried to compile and run the flutter app. Unfortunately I get the following error:
Code:
FAILURE: Build failed with an exception.
* Where:
Build file 'C:\Users\rbrown3\AndroidStudioProjects\flutter_app\android\build.gradle' line: 26
* What went wrong:
A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
> Failed to notify project evaluation listener.
> Uninitialized object exists on backward branch 142
Exception Details:
Location:
com/android/build/gradle/internal/pipeline/VariantInfoImpl.<init>(Lcom/android/build/gradle/internal/scope/VariantScope;)V @200: goto
Reason:
Error exists in the bytecode
Bytecode:
...bytecode listing omitted for brevity...
Note that I also took a look at the build.gradle file that contained the offending line . Line 26 just contains:
Code:
project.evaluationDependsOn(':app')
I did not edit that line at all. In fact, I did not change anything, not even in the main.dart file.
Have I found a bug in the Flutter plugin? Or is it an Android Studio bug? Why does a pristine installation of Android Studio fail to compile default code due to a flaw in a gradle build file??? More importantly, what is the flaw causig these compilation failures and how do I fix it?
