AsyncTask not available in Android Studio - android

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

android plugin issue, asks to update, but already updated all

I know this has been asked before as well, but I have done all I can.
I have updated all I can from SDK manager, but still I am getting this issue with my project that I just created.
There is no functionality I have given yet, but the issue says the plugin is too old, please update or change the ANDROID_DAILY_ENVIRONMENT variable.
This is my gradle file
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.example.manav.loginapp"
minSdkVersion 21
targetSdkVersion 24
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-v7:24.2.1'
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha1'

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 {
compileSdkVersion 23
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.

Why can't I import LinearLayoutManager and RecyclerView?

I can import everything else from the Android library except for those two. I'm trying to import them from android.support.v7.widget which doesn't work, but importing fragment and activity classes from android.support.v4.widget does work.
My Gradle Build looks like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.frisosapps.planner"
minSdkVersion 14
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-v7:22.2.1'
compile 'com.android.support:support-v4:22.2.1'
}
Should I add something to this or should I look for the cause elsewhere?
To use RecyclerView, use
compile 'com.android.support:recyclerview-v7:23.1.1'
you'll need to include the RecyclerView dependency as its standalone library
compile "com.android.support:recyclerview-v7:23.1.1"

Android Studio support v4

I know this question was asked several times, but none of the answers helped me so far...
All I did was generating a preferences screen with Android Studio and now it tells me that NavUtils cannot be found. Even though my build.gradle looks right (I guess):
apply plugin: 'com.android.application'
android {
compileSdkVersion 19
buildToolsVersion '20.0.0'
defaultConfig {
applicationId "com.brobox.getyourshitdone"
minSdkVersion 15
targetSdkVersion 19
versionCode 1
versionName '1.0'
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:cardview-v7:+'
compile 'com.android.support:recyclerview-v7:+'
compile 'com.android.support:palette-v7:+'
compile 'com.android.support:support-v4:20.0.+'
compile files('libs/android-support-v4.jar')
}
I hope someone can help :/
Edit:
Just created a new project on my laptop and generated the SettingsActivity again. This is my gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 19
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "com.brobox.getyourshitdone"
minSdkVersion 14
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:support-v13:20.0.0'
compile 'com.android.support:support-v4:20.0.0'
}
Still got the same error <.<
You have to remove this line implementation files('libs/android-support-v4.jar') and you have to remove this file.
The support library should only be added by gradle. And you have done that in this line implementation 'com.android.support:support-v4:20.0.+'.
YourtargetSdkVersion and your compileSdkVersion are also weird. Those values are not supported with the L developer preview.
compileSdkversionshould be 'android-L', targetSdkVersion should be 'L'.
Press this button, and clean rebuild project.
And add to dependencies :
dependencies {
compile 'com.android.support:appcompat-v7:+'
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:cardview-v7:+'
compile 'com.android.support:recyclerview-v7:+'
compile 'com.android.support:palette-v7:+'
}
Well some time passed and now it works! I don't know what solved it exactly but I did the following:
I updated to Android Studio 0.8.12 manually, because that was the only way to update it
In a new project I tried to manually add a SettingsActivity and therefore added support-v4 to my repositories
Thanks for all your help on this silly question...
