Serious Android Studio update issues

Question

I had been working on Android Studio version 1.1. 2-3 days before, it asked for update to 1.2. I thought it was gonna get all the better. But, now I am facing the following problems:

Warning:The project encoding (windows-1252) does not match the encoding specified in the Gradle build files (UTF-8).
This can lead to serious bugs.

and,

This version of the rendering library is more recent than your version of Android Studio. Please update Android Studio

I have tried uninstalling-reinstalling it like 7 time already but problems don't go away. I have never messed up with Android Studio settings.

Why is this happening? and What should I do to resolve it? I am just enough desperate that I was gonna Format my computer but thats a mammoth task so I am asking here.

P.S: I tried changing the encoding but nothing works. Thanks.

EDIT 1 : Following Sandspy's advice build.gradle contains the following with no support library.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.example.mankum93.geoquiz"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
}

EDIT 2: Here is the problem still persisting:

EDIT 3: After changing from MNC to Android Lollipop.

EDIT 4: I guess I am gonna download the 1.2 stable binary and not update until 1.3 stable is released. If anyone solves this problem concretely please post the solution here.

Answer 1

For any reason, Android Studio generates the projects in windows-1252 enconding, but the IDE enconding still being UTF-8. You can change it in File -> Settings -> Editor -> File encoding -> Project Encoding; like weston said in the last answer.

For reference, the same issue was answered in this sites:
