Android project there is no output dir after gradle build success?

I am learning Gradle for Android recently. For learning impressively, i create all android application files manually.
my project dirs as below
package name : com.wonbin.gradledemo
project build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
}
}
allprojects {
repositories {
jcenter()
}
}
app module build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "com.wonbin.gradledemo"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "adroid.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
debug {
}
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
}
}
lintOptions {
htmlReport true
htmlOutput file("lint-results.html")
}
}
dependencies {
compile fileTree(dir:'libs',include:['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',{
exclude group: 'com.android.support',module: 'support-annotations'})
compile 'com.android.support:appcompat-v7:23.4.0'
testCompile 'junit:junit:4.12'
}
./gradlew build is successful and there are 'intermediates' and 'generated'
dirs , but no outputs dir, i don't know what to do!
Thanks a lot!

You need not only to build, but to assemble it as well.
To do this you can run a gradle task
assembleDebug
Or use Build -> Build APK main menu item

android- Gradle: An issue occurred configuring root project android studio

I migrated from eclipse to android studio. I've create a new project and I want to run it on genymotion. When I press run icon, it begins to compile and give me this error :
Error:Gradle: A problem occurred configuring root project 'Khabar'.
> Could not resolve all dependencies for configuration ':classpath'.
> Could not resolve com.android.tools.build:gradle:1.1.0.

This is some parts of my build.gradle :
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "example.ir.khabar"
minSdkVersion 8
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
build.gradle in root :
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "example.ir.khabar"
minSdkVersion 8
targetSdkVersion 20
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-v7:20.0.0'
compile files('libs/universal-image-loader-1.8.4-with-sources.jar')
}
Could you help me? my gradle version is gradle-2.2.1-all

For me, the solution was to add the http url for jcenter, instead of https:
buildscript {
repositories {
jcenter {
url "http://jcenter.bintray.com/"
}
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

In addition to Al's answer, I also had to put the url inside allprojects:
allprojects {
repositories {
jcenter {
url "http://jcenter.bintray.com/"
}
}
}

I was having the same issue on Ubuntu Mate 18.04. I was able to fix it by replacing ibm-java80-jdk & ibm-java80-jre with openjdk. Also, I did update my DNS to cloudflare DNS. But I don't think it had anything to do with the fix.

add google() in your gradle inside the repositories section will solve your problem..
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
}
}
allprojects {
repositories {
jcenter()
}
}

Android Studio gradle sync failed to find library

So I'm working on project in AndroidStudio 0.8.1 beta and I want to make use of a library I found on github (https://github.com/derekbrameyer/android-betterpickers). I add the dependency like it says inside the README.md but when I try to sync the project with the gradle files it says:
Failed to find: com.doomonafireball.betterpickers:library:1.5.2
Here is my build.gradle file:
apply plugin: 'com.android.application'
buildscript {
repositories {
maven { url 'http://repo1.maven.org/maven2' }
}
}
repositories {
mavenCentral()
}
android {
compileSdkVersion 19
buildToolsVersion '19.1.0'
defaultConfig {
applicationId 'gtsarandum.syncc'
minSdkVersion 14
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:support-v4:19.+'
compile project(':extendedCalendarView')
compile project(':src')
compile 'com.github.gabrielemariotti.cards:library:1.7.3'
compile 'com.github.gabrielemariotti.cards:library-extra:1.7.3'
compile 'com.doomonafireball.betterpickers:library:1.5.2'
}
Last time I had this problem with gabriellemariotti.cards:libraryd:1.7.3 I added maven { url 'http://repo1.maven.org/maven2' } inside the buildscript as you can see above.
Is there something else I have to add? If not, how do I solve this problem?
Many thanks in advance!

My fix was to add:
allprojects {
repositories {
mavenCentral()
}
}
to the build.gradle file

Try alter 'gradle.settings' with an include statement for the path/lib not being found.

Don't use HTTP Proxy. Android Studio -> File -> Settings-> HTTP Proxy -> No proxy

Can't integrate AdMob in my app (Android Studio)

I need to implement AdMob in my project, so first I wanted to set up Google Play Services
Did everything as on official site:
-Download latest (4.4.52) Google Play Services in SDK manager
-In build.gradle in dependencies added
compile 'com.google.android.gms:play-services:4.4.52'
Got this error when sync project:
Error:A problem occurred configuring project ':app'.
Could not resolve all dependencies for configuration ':app:_debugCompile'.
Could not find com.google.android.gms:play-services:4.4.52.

Please, help

Please check your build.gradle and make sure that the mavenCentral reposority is included. Your file should look something like this:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.9.+'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
android {
compileSdkVersion 19
buildToolsVersion "19.1"
defaultConfig {
minSdkVersion 15
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:19.1.+'
compile 'com.google.android.gms:play-services:4.4.52'
}

setup actionbar sherlock in android studio 0.4.2

I am developing an android project by using actionbrsherlock library. after adding the actionbarsherlock library in android studio , my directory structure is
MYAPPLICATION
- app
- gradle
- libraries
- actionbarsherlock (library project)
build.gradle
setting.gradle
build.gradle
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.7.+'
compile project(":libraries:actionbarsherlock")
}
}
allprojects {
repositories {
mavenCentral()
}
}
setting.build
include ':app'
include ':libraries:actionbarsherlock'
after running following error occured,
A problem occurred evaluating root project 'MyApplication'. > No
signature of method:
org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.compile()
is applicable for argument types:
(org.gradle.api.internal.project.DefaultProject_Decorated) values:
[project ':libraries:actionbarsherlock'] Possible solutions:
module(java.lang.Object)
UPDATE:
I upgraded my android studio to 0.4.4. and change the build.gradle file. one can find the whole setup on github https://github.com/manishpathak99/AndroidStudio.

First I will strongly recommend you to upgrade your studio to version 0.4.3 because there were some dependencies related issues in 0.4.2 release .
Answer :
You are adding module dependencies at wrong place in build.gradle file . Your module's build.gradle file should look like this :
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.7.+'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
android {
compileSdkVersion 19
buildToolsVersion "19.0.0"
defaultConfig {
minSdkVersion 10
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
debug {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
// Your all module dependencies should be defined here
compile project(":libraries:actionbarsherlock")
}
Recommended Solution :
ActionbarSherlock library has its maven dependency, In such cases no need to download the whole library and add it as as module in your project, instead add the maven gradle dependency in your module's build.gradle file like
dependencies {
compile 'com.actionbarsherlock:actionbarsherlock-i18n:4.4.0#aar'
}
That's it.
