Fixing A Run Time Error for An Android Program

when I was trying to run a simple program , I got an error related to Gradle :
Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration':app:_debugUnitTestCompile'.
> Could not resolve junit:junit:4.12.
Required by:
MyApplication:app:unspecified
> Could not resolve junit:junit:4.12.
> Could not get resource 'https://jcenter.bintray.com/junit/junit/4.12/junit-4.12.pom'.
> Could not GET 'htps://jcenter.bintray.com/junit/junit/4.12/junit-4.12.pom'.
> Connection to htps://jcenter.bintray.com refused .
I don't know how can I fix it , please help .( I am currently using the android studio version 2.1.2 )
my module build-gradle includes these codes:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.example.n5110.myapplication"
minSdkVersion 15
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-v7:23.3.0'
compile 'com.android.support:design:23.3.0'
}

The problematic part with your gralde.build is this line:
testCompile 'junit:junit:4.12'
This is a unit testing library. If you are just starting and are probably not gonna write testcases for your project then, you can resolve the issue by simply deleting the line. If however you essentially need that library then refer here.

Add Maven Repositories it should work, its described at https://github.com/loopj/android-async-http in gradle section
this is example of my gradle :
apply plugin: 'com.android.application'
repositories {
maven {
url 'https://repo1.maven.org/maven2/'
}
}
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.mine.android"
minSdkVersion 10
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'])
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.loopj.android:android-async-http:1.4.9'
}
}

Just add below code in build.gradle
repositories {mavenCentral()maven {url"https://oss.onatype.org/content/repositories/snapshots/" } }

Android Gradle build - dependencies Error

I use:
android studio 1.5.1
java version "1.7.0_80"
I want to create a new android project as
Min Api-version = 15
But android studio cannot create new application , a dialog is opened with this title :
"Building 'MyApplication' Gradle project info"
and its content is :
a text: "Gradle: Resolve dependencies ':app:_debugCompile'"
and a progressBar;
unfortunately this dialog is opened for long time,just now ...
I had some projects , but when I want to build gradle for them below error is shown to me :
Error:(3, 0) Gradle DSL method not found: 'android()'
Possible causes:The project 'e-project' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
Fix plugin version and sync project
The project 'e-project' may be using a version of Gradle that does not contain the method.
openGradleSettings Gradle settings The build file may be missing a Gradle plugin.
"apply.gradle.plugin Apply Gradle plugin
Edit 1: I added build.gradle
apply plugin: 'application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {

Unable to add Minim-Android library in Android Studio with jitpack

I am trying to add to my build.gradle file in Android Studio the following dependency:
https://android-arsenal.com/details/1/1883
I followed the intstructions found in package tab of this page, but when I tried to build the project I got the following message:
Error:(32, 13) Failed to resolve:
com.github.DASAR:Minim-Android:a73b596916
Anyone can help me?
I also tried to download the project code and import it in Android Studio as a module, but it wasn't recognized as a library from the wizard.
Thank you all in advance.

You can download relative API in your AS SDK Manager, then add it in build.gradle. After that, check out the compileSdkVersion, targetSdkVersion are same with appcompat. My build.gradle is:
apply plugin: 'com.android.application'
android {
compileSdkVersion 19
buildToolsVersion "21.0.1"
defaultConfig {
applicationId "com.example.android"
minSdkVersion 9
targetSdkVersion 19
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-v7:19.0.0'
}
my sdk is 19

Best option is to fork the project and add a Gradle build file. Then use JitPack to build the fork.
Note that the project has dependencies in a libs/ folder so these would need to be converted to dependencies in Gradle.

error: cannot find symbol class Android Studio

This error hapens after update mac osx or system (I don't know).
It was after I open project that I closed one weak ago.
My settings.gradles is:
include ':app' , ':api', ':daogenerator'
project(':mobilneapi').projectDir = new File("/Users/AndroidstudioProjects/Modules/api")
project(':daogenerator').projectDir = new File("/Users/AndroidstudioProjects/Modules/daogenerator")
And my app gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "pl.wm.myapplication"
minSdkVersion 15
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'])
compile project(':api')
compile project(':daogenerator')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.0.1'
}
When I add import into MainActivity in Main Project.
I have got error after compile:
Error:(6, 24) error: cannot find symbol class Cache
What was wrong?
The same error on gradle build tools 1.3.0 and 1.2.4

try the usual stuff:
rebuild/clean project.
sync project with gradle files.
force close studio64.exe and restart it
restart the computer!
I hate these kind of errors, when nothing works, I usually end up creating a new project and start copying everything to it.
