Adding android support library v4 r13 to my android project

I tried to add the following library as a dependency in my android project:
compile 'com.thehayro:infiniteviewpager:0.4'
which gives me the following gradle error when I build:
A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
> Could not find com.google.android:support-v4:r13.
Searched in the following locations:

I tried manually adding the android support library and installing it with the android sdk manager but neither of those things worked.
I also read somewhere that I could try to find a download for the library and manually add it but there must be a more elegant way then that.

Java, scala with gradle plugin in android studio

I saw the sample here to use scala with gradle plugin. I created a new android studio project. These are my gradle builds
Project build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.1'
classpath "jp.leafytree.gradle:gradle-android-scala-plugin:1.4"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Module app build.gradle
apply plugin: "com.android.application"
apply plugin: "jp.leafytree.android-scala"
android {
compileSdkVersion 24
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.example.ashwinxd.escalaandroidapp"
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-v7:24.1.1'
compile "org.scala-lang:scala-library:2.11.7"
compile "org.scala-lang:scala-library:2.11.7"
compile "com.android.support:multidex:1.0.1"
compile "org.scalaz:scalaz-core_2.11:7.1.0"
}
The project compiles fine. There is no scala src directory generated. How do I proceed with using scala alongside java files? Is it necessary to use them in a source directory called scala? If so how do I generate it?

You have to create your own src/main/scala directory. That is where the scala gradle plugin looks for the scala source files. Just like the android plugin will look at src/main/java and src/androidTest/java.
That page describes you can customize that directory location at Put scala source files.

Gradle build failed for two dependencies

I am trying to build gradle with the following dependencies. but its not compiling. I have tried a lot by changing the versions by seeing forums. I search for the dependencies in project structure dialog and found the following two.
de.hdodenhof:circleimageview:2.0.0
com.mcxiaoke.volley:library-aar:1.0.1
Actually I am using two pc. This was build in another pc with following
de.hdodenhof:circleimageview:1.2.1
com.mcxiaoke.volley:library-aar:1.0.19
Still no luck and the gradle build taking 20-25 minutes each time
Main build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
App build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.example.map"
minSdkVersion 19

}
}
}

}
dependencies {
compile('com.mapbox.mapboxsdk:mapbox-android-sdk:0.7.4#aar') {

}
compile 'de.hdodenhof:circleimageview:2.0.0'
compile 'com.mcxiaoke.volley:library:1.0.19'
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'
compile 'com.android.support:recyclerview-v7:23.0'
}

This sounds like gradle is unable to reach the remote repository. Does your firewall block it, is your internet connection working,...?

Error:(20, 0) Gradle DSL method not found: 'compile()'

I have looked at other related but none seems to Solve my Problem in Gradle.
Here is my Build Gradle (Module App )
apply plugin: 'com.android.application'

}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile files('libs/android-support-v13.jar')
compile 'com.android.support:appcompat-v7:22.0.0'
}
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {

// NOTE: Do not place your application dependencies here; they belong

}
dependencies {
compile 'com.android.support:support-v4:19.0.0'
compile fileTree(dir: 'libs', include: ['*.jar'])
} apply plugin: 'application'
allprojects {
repositories {
jcenter()
}
}
}
The are it gives me
"Error:(20, 0) Gradle DSL method not found: 'compile()'
Possible causes:The project 'Project' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file
The build file may be missing a Gradle plugin. Apply Gradle plugin"
What am I doing wrong ?

You cannot add compile dependencies to global build.gradle file. Removing the second dependencies block in your global build.gradle file would fix the error.

Error:(22,0) Gradle DSL method not found: 'compile()'

Hi guys I'm having a problem Gradle DSL method not found: 'compile()'. Most of the discussions I read suggest that I add compile 'com.android.support:support-v4:21.+' to individual's module build file and in my case the compile 'com.android.support:support-v4:21.+' is already there. If I remove the one I added on the top most level build file I get this error (Error:Artifact 'support-v4.jar (com.android.support:support-v4:21.0.3)' not found. Android studio 1.0.2).
Please help, here are my gradle files:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
dependencies {
compile 'com.android.support:support-v4:21.+'
}
Gradle file under App folder:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.example.ntokozo.myapplication"
minSdkVersion 15
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-v7:21.0.3'
compile 'com.android.support:support-v4:21.0.3'
}
Thank you.

Remove the dependencies block from the top level build.gradle file.
dependencies {
compile 'com.android.support:support-v4:21.+'
}
Also update your sdk files.
