failed to build tool version android - android-studio

Question

I tried to open an old project of mine in a freshly installed android studio (today), It gave me this error :
failed to find build tools revision 23.0.0 rc2
install build tools 23.0.0 rc2 and sync project
I looked for it in the internet and I tried to add this in the gradle file :
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"
}
And it gave me another error:
gradle DSL method not found: 'android()'
possible causes:
the project may be using a version of gradle that does not contain the method.
gradle settings.
the build file may be missing a gradle plugin.
apply gradle plugin.
this is my gradle file :
// 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:1.2.3'
}
}
allprojects {
repositories {
jcenter()
}
}
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"
}

Answer 1

Right click on your project > Open Module Settings > Properties Tab, then change :
Compile Sdk Verion to API 23: Android 6.0
Build Tools Version 23.0.0

Answer 2

I checked the build tools version installed in my Android Studio and I have Android SDK Build-Tools rc3, Not rc2.
I changed it in build.gradle (Module App) to
android {
compileSdkVersion 22
buildToolsVersion "23.0.0 rc3"}
After that it works.
Check if you have the same issue.

Answer 3

In your top level build.gradle you have to remove the android block
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"
}
Just use:
// 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:1.2.3'
}
}
allprojects {
repositories {
jcenter()
}
}
You have to use the android block, in the app/build.gradle where you should define something like:
apply plugin: 'com.android.application'
android {
compileSdkVersion XX
buildToolsVersion "XX.X.X"
defaultConfig {
minSdkVersion XX
targetSdkVersion XX
versionCode 1
versionName "1.0"
}
buildTypes {
release {
//......
}
}
}
dependencies {
//......
}

theres 2 gradle files
the one you have to modify is the one under this directory
APPLICATION NAME / APP / BUILD.GRADLE
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "PUT THE CODE YOU WANT HERE EX "23.0.0 r3""
defaultConfig {
applicationId "org.app.appname"
minSdkVersion 10
targetSdkVersion 22
versionCode 9
versionName "1.10.3"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile 'com.google.android.gms:play-services:7.5.0'
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:support-v4:22.2.1'
compile files('libs/volley.jar')
}
not the one which looks like these
// 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()
}
}

Answer 5

In my case I tried everything and finally I had to do a simple change from this
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "23.0.0 rc2"
}
to this
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "23.0.0" //DELETE rc2 AND SYNC PROJECT
}

Answer 6

It depends on which version of Android SDK Build-tools you have installed, you could check it via the SDK Manager, in my case I haven't the 23.0.0 rc2 installed but the 23.0.1, so you need to edit your app/build.gradle
for me it was then:
android {
compileSdkVersion 22
buildToolsVersion "23.0.1"
}
