Android Studio project sync FAILED

I attempted to import a project that Udacity's android course provided, but there were some issues. In the build.grade(app module) I changed compile toimplementation and testCompile to testImplementation. The project synced successfully, but when I executed the project on the emulator it gave me the following errors.
Could not find com.android.tools.build:aapt2:3.3.1-5013011.
Searched in the following locations:

I think the required libraries needed to build cannot be found, but I don't know how to solve this. I googled the problem, but I can't find a solution.
My build.gradle file is this:

android {
compileSdkVersion 23
defaultConfig {
applicationId "com.example.android.miwok"
minSdkVersion 15
targetSdkVersion 23

build.grade(project) is:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.3.1'

}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

Beginning with Android Studio 3.2, the source for AAPT2 (Android Asset Packaging Tool 2) is Google's Maven repository.
To use AAPT2, make sure that you have a google() dependency in your build.gradle file.
allprojects {
repositories {
google()
jcenter()
}
}

Check the official documentation.
The AAPT2 (Android Asset Packaging Tool) is a build tool that Android Studio and Android Gradle Plugin.
Android Gradle Plugin 3.0.0 and higher enable AAPT2 by default.
With Android Studio 3.2 to use AAPT2, make sure that you have a google() dependency in your build.gradle:
buildscript {
repositories {
google() // here
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'
}
} allprojects {
repositories {
google() // and here
jcenter()

Gradle Project Sync Failed, Kotlin

I am using a beta Kotlin and Android-Studio channel. After update to the latest version i got some gradle sync error.

Please, anyone has an idea about this? I don't really know how can I solve this? I could not find any solutions out there.

Change your repositories in buildscript and allprojects into:
{
google()
jcenter()
mavenCentral()
maven {
url 'https://dl.bintray.com/kotlin/kotlin-dev/'
}
}
This works for me.

First, I updated Kotlin plugin thru tool, Kotlin, configure kotlin plugin update.
After, in App directory, in build.Gradle file search:
repositories {
// You need to add the following repository to download the
// new plugin.
google()
}
I add a new repository
maven { url 'C:/Program Files/Android/Android Studio/gradle/m2repository/'}
this is the path thru my local directory where the resources are. After this try again to sync

Change and try
classpath 'com.android.tools.build:gradle:3.1.0-alpha04'
to
classpath 'com.android.tools.build:gradle:3.0.0'
It may be due to the alpha release of gradle.

Use below version of kotlin in build.gradle(Project)
kotlin_version = '1.1.4-3'
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
Declare dependency of kotlin in build.gradle(Module) as below
compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"

check your Kotlin version in build.gradle.
I got the same issue when the version was 1.1.0 which was added by default.
changed to recent version 1.3.21 then it is working fine.

This solution has worked for me for React Native(0.63) after installing react-native-image-picker by Ray Eldath, from above comment
//in android.build.gradle
{
google()
jcenter()
mavenCentral()
maven {
url 'https://dl.bintray.com/kotlin/kotlin-
dev/'
}
}

First, close Android studio, delete the .gradle folder, and then open Android Studio again, probably as an administrator
This will make it sync from the start, and solve the issue.
This issue was resolved for one of my peers.

Uninstall the Kotlin plugin (Preferences > Plugins > Kotlin > Uninstall) and use the version that comes with the IDE .

android : cannot build project after upgrading Android Studio to 2.3

So, happily updated my Android Studio from stable version 2.2 to canary channel 2.3.
But, unfortunately, it has serious bug. Project is not able to build.
I tried opening my previous projects and also tried creating new sample application, I got same below error:
Gradle 'MyApplication' project refresh failed
Error:A problem occurred configuring project ':app'.
build.gradle(project):
// 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:2.3.0-alpha1'
// 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
}
build.gradle(app):
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
defaultConfig {
applicationId "com.example.chint.myapplication"
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
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-v7:25.0.0'
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'
compile 'com.android.support:design:25.0.0'
testCompile 'junit:junit:4.12'
}
Am I the only one with this issue ?

So, be careful while this dialog appears:
Choose "Remind me later" and NOT "Update"
Stay with the build version you already have.
Incase, you pressed Update, so just rollback your Android Gradle Plugin classpath in build.gradle(project) to below one:
classpath 'com.android.tools.build:gradle:2.2.2'
This worked for me.

You should update your Android Studio gradle manually.
1° Step:
Follow this path and get your gradle version
C:\Users\[USER_NAME]\.gradle\wrapper\dists
Here you will get "gradle-X.X" (X- is version) in my case it was "gradle-3.3-all"
2° Step:
Go to the following link :
https://services.gradle.org/distributions/
Download your respective version zip file and just past it in the last folder with long random name.
C:\Users\[USER_NAME]\.gradle\wrapper\dists\gradle-x.x\55gk2rcmfc6p2dg9u9ohc31212 HERE
Now open the Android studio, I hope this will work.

I fought a similar issue and resolved it with the addition of 2 characters...
And after updating the gradle-wrapper.properties to target 3.2.1 everything was great for me
distributionUrl=https\://services.gradle.org/distributions/gradle-3.2.1-all.zip

If you import external libraries apply changes for "allprojects"
// 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:2.3.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
mavenCentral()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

Where can I put individual dependencies in Android Studio?

I am trying to install Picasso (http://square.github.io/picasso/) for use in Android Studio. One of the steps is to add this line: compile 'com.squareup.picasso:picasso:2.5.2' in build.gradle under dependencies. However, there is a message in gradle that tells me not to insert individual dependencies in the dependencies folder. What should I do?
// 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:1.3.0'
// 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
}

You need to add it to the gradle.build file that is located in the "app" directory, not the one in your project directory. find the gradle.build file that sits within the "app" directory of your project.
Here is mine as an example:
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.your.packagename"
minSdkVersion 15
targetSdkVersion 21
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
repositories { mavenCentral() }
dependencies {
compile 'com.android.support:appcompat-v7:18.0.+'
compile 'com.facebook.android:facebook-android-sdk:4.0.0'
compile 'com.parse.bolts:bolts-android:1.+'
compile 'com.parse:parse-android:1.+'
}
And a link to some supporting documentation:
http://developer.android.com/tools/building/configuring-gradle.html

Screenshot of the build.gradle(Module:app file)
Take a look at the image.
Do you see that there are actually 2 build.gradle files?
what you need is the (Module:app) gradle build file select that and paste the link in the dependencies part in the bottom of that file just like what i have done , then Android Studio will ask you to sync the file.
Do it.
It will download the dependency from your link provided and integrate with the project
Hope this helps..

Can't import project to android studio

I'm trying to use this library
I've added
compile 'net.rdrei.android.dirchooser:library:2.0#aar'
to dependecies.
My top level build file
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.8.+'
}
}
allprojects {
repositories {
mavenCentral()
}
}
And it gives me error "failed to refresh gradle project" with reference to the project, that I'm trying to import.

This library is not on Central Maven as aar.
Check here:
http://search.maven.org/#search%7Cga%7C1%7Cnet.rdrei.android.dirchooser
it is an apklib format.
I've checked the snapshots repo, and here you can find this library.
https://oss.sonatype.org/content/repositories/snapshots/net/rdrei/android/dirchooser/library/
To use the snap repo you have to change your script:
repositories {
mavenCentral()
maven {
url "https://oss.sonatype.org/content/repositories/snapshots"
}
}
Then add you depencency, for example
compile 'net.rdrei.android.dirchooser:library:2.1-SNAPSHOT'

The answer provided by #unify #GabrieleMariotti and #AndyJoiner is correct. However it confused be since we have two gradle files - a project level gradle and a inner gradle (where you write your dependencies). The solution is to add the code suggested by #AndyJoiner inside your inner gradle.
Since I was confused as to where to add the code, which took me an hour to figure out, I don't want it to happen to others. So, I am posting my both gradle files.
Project Level Gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.0.0'
}
}
allprojects {
repositories {
jcenter()
}
}
Inner Gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.itcse.materialdesignsearchviewlikegoogleplay"
minSdkVersion 15
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
// Add the code for repositories here
repositories {
mavenCentral()
maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
maven { url 'http://guardian.github.com/maven/repo-releases' }
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
// Add the dependencies here
compile 'com.quinny898.library.persistentsearch:library:1.0.0-SNAPSHOT#aar'
}
Hope this help others in future.

This worked for me:
repositories {
maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }
You can find the repository here
https://oss.sonatype.org/#nexus-search;quick~dirchooser

After trying the answer by Gabriele and a bit more digging, this worked for me
repositories {
mavenCentral()
maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
maven { url 'http://guardian.github.com/maven/repo-releases' }
}
dependencies {
compile 'net.rdrei.android.dirchooser:library:2.2-SNAPSHOT#aar'
}
