Emulators are not showing in Android Studio

In Android Studio the Emulators are not showing . I tried that disabling ADB Integration. but it is not working for me.
Please give me solution for this problem.

Maybe your project is not compatible (API version) with the target emulator. Check build.gradle file if the targetSDK and minimumSdk version is lower or equal to the sdk version of your Emulator.
Be sure that your compiledSdkVersion matches minSdkVersion and supported by targetSdkVersion. For example:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "24.0.0"
defaultConfig {
applicationId "zeta.sqlitetest3"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
}

Android gradle sync error-Could not create an instance of Tooling API implementation

I recently installed android studio 2.1.2 and I am getting this error:
Error:Could not create an instance of Tooling API implementation using the specified Gradle distribution 'https://services.gradle.org/distributions/gradle-2.10-all.zip'.
I used to have 1.3.1 previously but I opened it recently after a while and it was showing the same error so I decided to do a fresh installation but the error persists.
Here is what the build.gradle file looks like for the app:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "24.0.1"
defaultConfig {
applicationId "com.example.sanchitverma.myapplication"
minSdkVersion 23
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'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
}

Unable to sync gradle

I get error messages when I try to add recyclerview and cardview dependencies to my build.gradle. Here is my build.gradle:
apply plugin: 'com.android.application'
android {

buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.truewebdev.applytheme"
minSdkVersion 17
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support.recyclerview-v7:23.2.0'
compile 'com.android.support.cardview-v7:23.2.0'
}
Here are the error messages:
If I try to install repository, I get the following:
What is wrong here?

Did you download the Android Support Repository from the SDK Manager?
From android docs:
Make sure you have downloaded the Android Support Repository using the SDK Manager.

Im currently using android studio 1.5. My problem is when I try to run my google maps activity in my emulator, it kept showing the prompt "App wont run unless you update google play services". What now?

AsyncTask not available in Android Studio

I am using Android Studio 1.2. Every SDK must have AsyncTask , but my Android Studio is not able to recognize the class.Even not showing in import and autoassist.
Similarly if I write no suggestion in Autosuggest
Gradle Script:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "22.0.0"
defaultConfig {
applicationId "com.appxperts.printknot2"
minSdkVersion 11
targetSdkVersion 21
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-v7:22.1.1'
compile project(':libraries:floatingedittextlibrary')
compile files('libs/gson-2.2.4.jar')
compile 'com.larswerkman:HoloColorPicker:1.5'
compile 'com.doomonafireball.betterpickers:library:1.5.5'
compile 'com.google.android.gms:play-services:3.1.+'
}

I solved it myself.The problem was with Android Studio on Ubuntu.It is not able to automatically import AsycTask.Not even in auto-suggestions.Simply added
import android.os.AsyncTask
