Cannot resolve symbol 'Theme' in styles.xml (Android Studio) - android

Since today, Android Studio can't find the AppCompat themes in styles.xml, but for example AppCompatActivity in code does get recognized. My Android Studio version is 2.2.2, Build #AI-145.3360264
I already tried upgrading to the latest build tools, compile sdk (25) version etc. but it didn't fix the problem.
At the moment I have installed the following (from sdk manager):
android api: 19 and 23
sdk platform tools: 25.0.1
sdk tools: 25.2.3
build-tools: 23.0.2 and 25.0.1
support repository: 40
google repository: 39
and a few others, that shouldn't be necessary to list here.
build.gradle of app:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '25.0.1'
defaultConfig {
applicationId "xxx.xxxxxxxx.xxxxxxxxx" //not the real applicationId
minSdkVersion 14
targetSdkVersion 19
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile files('libs/RootTools.jar')
compile 'com.android.support:support-v4:23.+'
compile 'com.android.support:support-v13:23.+'
compile 'com.android.support:appcompat-v7:23.+'
compile 'com.android.support:design:23.+'
compile 'com.android.support:cardview-v7:23.+'
compile 'com.android.support.constraint:constraint-layout:1.0.0-beta4'
compile 'de.hdodenhof:circleimageview:2.1.0'
}

Another solution that worked for me with Android Studio 3.1.2:
delete these from build.gradle if you have them:
'com.android.support:appcompat-v7:27.1.1'
'com.android.support:design:27.1.1'
then sync,
then undo delete,
then sync again.

I encountered this after updating to Android Studio 3.1.
None of the other answers listed here worked for me, however when I switched my appcompat support lib version to the latest 28.0.0-alpha1 then back to 27.1.0 that it was on before, it worked.
Seems the new version of Android Studio lost connection to where the library was synced to and just needed to have it reset.

No need to change anything.
Just press small button on top "Sync Project with Gradle Files"

EDIT: As #Alexey noted, bug still appears in Android Studio v3.1.4
This worked for me:
Click File > Close Project
Reopen the project from Studio's dialog.

That's because of feature called "build cache" that is enabled by default in build Android Plugin since 2.3.0.
It creates files in build cache outside of project folder (in my case -- in \Users\%username%\.android\build-cache)
Theese files are intended to be common between your projects.
And then Android Studio is unable to navigate in theese files.
That's all.
If you want to disable Build Cache, add android.enableBuildCache=false to gradle.properties file. Then restart Android Studio.
more info here:
https://developer.android.com/studio/build/build-cache.html#disable_build_cache

I have had the same problem. The only solution that worked for me was to manually delete the support libraries in file system and sync the project to let Android Studio download them again.
Steps:
Go to your project folder in File system
Go to .idea\libraries
Delete all the Gradle__com_android_support_****.xml files
Open Android Studio
Select File > Sync with File System
Once that is done, Select File > Sync Project with Gradle Files
Build Project
And now your error should be gone!!!

you can hit file -> invalidate Caches / Restart ... if it doesn't fix the issue you can close the project (file-> close project) and import it (file -> new -> import project.

I switched support lib to version 27.1.1 and problem has been solved. Seems like some bug in 27.1.0

I went through the same problem when I upgraded to alpha-2.
I looked at this link: http://tools.android.com/recent, but the only thing that worked well was:
Change this:
Classpath 'com.android.tools.build:gradle:2.3.0-alpha2'
For this:
Classpath 'com.android.tools.build:gradle:2.2.3'
In your build.gradle (Project)

Only this worked for me
Close project (File> Close Project)
Import / Re-Open project again (NOT from Recent)
Error should be resolved now.
If that fails, try below-
Open build.gradle, remove appcompact-v7 dependency and sync project.
Add appcompact-v7 dependency and sync.

I encountered same problem like this.Just the difference is I was using Studio 2.2.3. This is what solved my problem:
In my project level gradle I had:
classpath 'com.android.tools.build:gradle:2.3.0-alpha2' (which was a result of updating studio)
which I replaced with:
classpath 'com.android.tools.build:gradle:2.2.3'
I think you should look for a compatible classpath for your gradle configuration.

I was having the same issue after linking Firebase to my app. Updating the build.gradle in the app module did the trick, updated to:
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.google.firebase:firebase-database:11.8.0'

I had also the same problem when I upgraded my android studio from 2.2.2 to 2.3 Canary Version.
Although the new beta version of 2.3 is released yet it is using the gradle plugin of 2.2.3 which is of stable version.
So just change the classpath dependency in buildscript of build.gradle project level from alpha to 2.2.3 and sync it. It'll resolve the issue or change to the more appropriate version with respect to your channel version.

In newer versions of Android Studio, we are asked to use 'AppCompat'. Some users uncheck that and still use the Theme.AppCompat. That makes up this error. Same happened with me.
Solution is to add this line in your build.gradle (app).
compile 'com.android.support:appcompat-v7:26.1.0'

#Daniel Wilson made a comment in one of the answers that solved this issue for me. I wanted to add add as an answer to draw more attention to this solution.
Updating compileSdkVersion and targetSdkVersion from 26 to 27 (and then of course updating the dependencies) eliminated the errors for me.

Mine was fixed by deleting the .gradle file from the folder and re-importing the project in Android Studio

I also faced the problem with Android Studio 3.1 , syncing does not help me.
Then I switched back to
`'com.android.support:design:27.1.0'` from : `'com.android.support:design:27.1.1'`
and added android.enableBuildCache=false to gradle.properties to disable build cache

This is weird, I encounter this problem as below:
Android Studio is 3.1.2
support lib version is 27.0.0
I solve this by below:
change support lib version to 27.1.0, and "Sync Project with Gradle Files", then this error disappear
change support lib version to 27.0.0,and "Sync Project with Gradle Files", then this error not appear again

Deleted .idea and .gradle from project folder.
Then sync with gradle files, it worked.

I ran into the same problem when updating the Android Studio software.
What I did was this:
Go to the Gradle Settings as follows (this path is for Mac, but should be similar on Windows):
Android Studio -> Preferences -> Build, Execution, Deployment ->
Gradle.
Then pick "Use default gradle wrapper (recommended)".
If you already have that option chosen then your problem must lie somewhere else.

I changed my gradle version from
classpath 'com.android.tools.build:gradle:2.3.0'
to
classpath 'com.android.tools.build:gradle:2.2.3'
and it works now!

In Android Studio 3.1.3, the simple work around:
"Sync Project with Gradle Files"

If none of these methods mentioned by other contributors does not work for you..
Then please simply ignore this...
Even flutter officials also said to ignore these errors..
Caution*** Only ignore after trying all the methods.If above methods solve your errors then fine otherwise you can ignore these..
This type of errors happen after installing latest version of flutter sdk,gradle ,android studio and other plugins -packages
If you are using latest version then you have to ignore these errors.

Can't determine type for tag '<macro name="m3_comp_bottom_app_bar_container_color">?attr/colorSurface</macro>'

I'm having a problem with running my android app:
Can't determine type for tag '<macro name="m3_comp_bottom_app_bar_container_color">?attr/colorSurface</macro>'
That is caused by 1.7.0:
implementation 'com.google.android.material:material:1.7.0'
You better stick to 1.6.0 till they fix this
implementation 'com.google.android.material:material:1.6.0'
In your build.gradle file where "dependencies" section is paste this:
implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.6.0'
in this section. And remove old strings with same text and other number versions. (in my case:
implementation 'androidx.appcompat:appcompat:1.5.1'
implementation 'com.google.android.material:material:1.7.0'
). Have worked for me.

Upgraded android gradle plugin to 7.2.2 and the problem is solved. Try updating Android Studio too
Rationale
To expand on the existing answers, the release notes for Material Components for Android 1.7.0 mentions that they have updated the minimum requirements for your project (emphasis mine):
New minimum requirements for your app's project:
Update to Android Gradle Plugin (AGP) version 7.2.0
Update to Gradle version 7.3.3
Update to Java 8 (version 1.8)
Update to Android Studio Chipmunk, version 2021.2.1
This is also mentioned in their (updated) Getting Started guide (again, emphasis mine):
5. Gradle, AGP, and Android Studio
When using MDC-Android version 1.7.0-alpha02 and above, you will need to make sure your project is built with the following minimum requirements, in order to support the latest build features such as XML macro:
Gradle version 7.3.3
Android Gradle Plugin (AGP) version 7.2.0
Android Studio Chipmunk, version 2021.2.1
Updating the Android Gradle Plugin
You can update the Android Gradle plugin as follows:
Gradle plugins DSL
The plugin declaration can be found in the top-level build.gradle/build.gradle.kts file:
plugins {
// Or "com.android.library"
id("com.android.application") version "7.2.2" apply false
}
Buildscript classpath
Update the AGP classpath dependency (usually in the top-level build.gradle/build.gradle.kts file):
classpath("com.android.tools.build:gradle:7.2.2")
update your build.gradle file as below:
classpath 'com.android.tools.build:gradle:7.2.1'
It will fix the issues, remember v7.3.x wont fix the issue, so stick to 7.2.1 as of now.
For Flutter User with this issue this is how you solve it::
Goto : build.gradle
change "classpath 'com.andriod.tools.build:gradle:5.6.0'"
to
"classpath 'com.andriod.tools.build:gradle:<latest version>'"
in my case :: classpath 'com.android.tools.build:gradle:7.2.1'
then goto :: android/gradle/wrapper/gradle-wrapper.properties
then change
distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.3-all.zip
to
distributionUrl=https\://services.gradle.org/distributions/gradle-<latest>-all.zip
in my case distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-all.zip
In build.gradle(:app),
Updating, compileSdk and targetSdk to 33 helped me(from 32).
In order to get over with this. Upgrade to the latest gradle version as well as latest Android Studio.
I was also facing this issue and I followed these steps :
Upgraded Android Studio to Android Studio Dolphin | 2021.3.1 Patch 1
gradle version to 7.3.1 in project build.gradle
kotlin version to 1.7.20 in project build.gradle
targetSdkVersion and compileSdkVersion to 33
latest version of dependencies in app's build.gradle
And the project is perfectly working fine now.
I resolved it by replacing implementation 'androidx.recyclerview:recyclerview:1.2.1' instead of implementation 'com.google.android.material:material:1.7.0' in build.gradle(:app)
Upgraded android gradle plugin >= 7.1.0 and the problem is solved.
classpath "com.android.tools.build:gradle:7.1.0"
After wasting 2 hours and ruining my mood solution was simply upgrading your android studio version, most probably you are using an older version like Arctic fox or something like that, upgrade to dolphin or something higher. Hope it help, and yes in dolphin version it will give error of 30.0.3 but don't worry it gives you an attached link to install 30.0.0 SDK in console itself, so chill and keep developing.
first, in the gradle build file, change the implementation from 1.7.0 to 1.6.0
Next, open the colors file and change the color of the tag (#) which has 7 digits to a 6 digit tag. Because usually the default color of tags on Android Studio is sometimes 7 digits or 6 digits
I solved this by :
Adding in build.gradle:
implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.5.0'
adding android:exported="true" in Manifest

Gradle build error of app after Android Studio 4.1 update

I have updated from Android Studio 4.0 to 4.1. After the update I cannot build my application anymore which worked fine before the update.
When I build the project I am getting the following exception:

Guys, I am out of ideas as I am no expert when it comes to gradle. Help would be most appreciated.
I found a temporary solution in downgrading my Android Studio version to 4.0.2.
Additionally, I changed the Android gradle plugin version to 4.0.2 and the gradle version to 6.1.1 which I had installed before. You can do this under File -> Project Structure -> Project.
Now I am able to run my application again. I am aware that this is only a temporary solution but at least I can work again on my application.
I will try to install Android Studio 4.2 Canary 15 the next days and check, if this works for me. I let you know.
This is what usually works for me every time i make an update, I hope it works for you.
Sometimes gradle build fails because, downloading some dependencies required by gradle for a successful build are missing and need to be downloaded. So make sure your computer is online.
-> Click on gradle (right side of your android studio), then toggle the highlighted button in the pic below.
Make sure its not highlighted, Cause if it is highlighted that means gradle is offline (has no access to internet)
Then rebuild project to download the missing gradle dependencies.
I hope you find this useful.
this solution may help. I had problems with this error showing up and I had no idea why. As it turns out, I save my android projects to a USB stick. The USB stick is formatted using PAL. I reformatted using NTFS and the problem has gone.
I had a similar problem this morning after updating my Android studio. In my case, previous projects run well but if I create a new project and attempt to run, I will get the said error message. I changed the Android Gradle plugin version to 4.0.2 and the Gradle version to 6.1.1 from the project structure dialog and I was able to run the app successfully afterward.
I have this problem when I try to build apk with capacitor Ionic in Android Studio. My solution was:
First change the Android Gradle plugin in build.gradle to classpath 'com.android.tools.build:gradle:4.0.2' and in gradle-wrapper.properties change Gradle version to distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip and press Sync Now.
When gradle sync is finish, close Android Studio Editor and go to project folder and inside android delete .idea and .gradle folders. Next you need to open PowerSheel in this location and run the code .\gradlew clean.
Finally, you can open the project with android studio using in vs npx cap open android or as you want, wait for sync gradle and then you can build your apk.
Changing the location my projects from a FAT32 formatted drive to an NTFS drive solved the problem for me.

Gradle Sync failed could not find constraint-layout:1.0.0-alpha2

Problem :
Error:Could not find com.android.support.constraint:constraint-layout:1.0.0-alpha2.
Required by:
myapp:app:unspecified
Background :
Android Studio 2.2 P 1
Support libraries for ConstraintLayout could not be installed/updated.
Just open Preferences > Appearance & Behavior > System Settings > Android and move to SDK Tools tab. Check the following fields and install.
In my case, that support libraries for ConstraintLayout were installed, but I was adding the incorrect version of ConstraintLayout Library in my build.gradle file. In order to see what version have you installed, go to Preferences > Appearance & Behavior > System Settings > Android SDK. Now, click on SDK Tools tab in right pane. Check Show Package Details and take note of the version.
Finally you can add the correct version in the build.gradle file
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha9'
testCompile 'junit:junit:4.12'
}
The fix is to update the android gradle plugin in your build.gradle.
This should work:
classpath 'com.android.tools.build:gradle:2.2.0-alpha2'
Or you can use the latest:
classpath 'com.android.tools.build:gradle:2.2.0-alpha3'
My problem was, that the SDK Tools updated it to the latest version, in my case it was 1.0.0-alpha9, but in my gradle dependency was set to
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha8'
So, you can change your gradle build file to
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha9'
Or you check "Show package details" in the SDK Tools Editor and install your needed version. See screenshow below. Image of SDK Tools
Ensure you have the maven.google.com repository declared in your module-level build.gradle file
repositories {
maven {
url 'https://maven.google.com'
}
}
2.Add the library as a dependency in the same build.gradle file:
dependencies {
compile 'com.android.support.constraint:constraint-layout:1.0.2'
}
I updated my android gradle plugin to 2.2.0-alpha4 and constraint layout dependency to 1.0.0-alpha3 and it seems to be working now
First I tried everything that I have read on stackoverflow...from updating gradle to XY version, to updating ConstraintLayout to XY version...I even update my SDK tools and Android Studio to the latest version...but nothing was working.
The only solution that worked for me was that I delete ConstraintLayout library from gradle and SDK, then I opened random xml layout and in Design view under Palette section search for ConstraintLayout. If you have successfully deleted library from your project then you will be able to install the library from there if you double clicked on ConstraintLayout element.
That has create next line in my app build.gradle:
'com.android.support.constraint:constraint-layout:1.0.0-beta1'
In my project build.gradle I have this:
classpath 'com.android.tools.build:gradle:2.2.2'
Android studio version 2.2.2
Alpha version is no longer available !
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
Just to make sure that in studio version 2.3 you won't see a dropdown near constraint-layout in sdk tools, it will by default install the latest version
To get the desired version check the box saying show package details and boom you can now choose the desired version you want to install
gradle com.android.tools.build:gradle:2.2.0-alpha6
constraint layout dependency com.android.support.constraint:constraint-layout:1.0.0-alpha4
works for me
For me it was a completely different issue. When I installed constraint dependancy in SDK tools, the tools somehow wrote them into the wrong directory. That is
/home/${USER}/Android/Sdk/extras/+m2repository+/com/.../constraint
instead of
/home/${USER}/Android/Sdk/extras/+android+/+m2repository+/com/.../constraint
Remedy:
Just copy the 1.0.0-alpha* directories into the latter path
While updating SDK tools, a dilog box presented with Constraint layout version that is going to get installed. Note that and update your dependency based on that. In my case it was installing beta3.
I changed my dependency like below. After that it worked.
compile 'com.android.support.constraint:constraint-layout:1.0.0-beta3'
In my case, I had to remove the previous versions first and download the latest one instead. v1.0 stable was released on Feb 23rd.
In my case, I had a multi-module project called "app" and "sdk". The "sdk" module is the one where I had added the constraint layout library. I got the error when I tried to incorporate "sdk" into a new multi-module project called "app2". The solution was to ensure I had added the Google Maven Repository to the project-level build.gradle file for "app2". The Google Maven Repository can be added by putting "google()" under allprojects.repositories in the project-level build.gradle file:
allprojects {
repositories {
jcenter()
google()
}
}
In my case, I was using AS 2.3 and I wanted to use the currently latest ConstraintLayout 1.1.3, but the latest version in my Preferences > Appearance & Behavior > System Settings > Android was 1.0.2.
To use ConstraintLayout 1.1.3, I updated my AS from 2.3 to currently latest 3.2.1, com.android.tools.build:gradle from 2.2.2 to 3.2.1, gradle from 3.3 to 4.6 and buildToolsVersion from 25.0.0 to 28.0.3.
I also added maven { url 'https://maven.google.com' } to the Maven repositories in the project-level build.gradle file and that solved my problem.
Just as a heads up to those still searching for this.
ConstraintLayout 1.0.1 and lower have been deprecated by maven.
For a list of available constraint layouts that can be downloaded, see below:
https://maven.google.com/web/index.html?q=Constrain#com.android.support.constraint:constraint-layout
The easiest solution at the moment, is to change
implementation 'com.android.support.constraint:constraint-layout:1.0.0-beta1'
to
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
I used com.android.support.constraint:constraint-layout:1.0.0-alpha2 with classpath 'com.android.tools.build:gradle:2.1.0', it worked like charm.
Not sure if I'm too late, but in case someone has still the error after an update of ConstraintLayout and Solver over the SDK Tools, maybe this solution could help: Error:(30, 13) Failed to resolve: com.android.support.constraint:constraint-layout:1.0.0-alpha4
Its available in androidx as following package
implementation "androidx.constraintlayout:constraintlayout:2.0.0-alpha1"
Update your constraint layout dependency to the relevant version from '1.0.0-alpha2'. In my case, I changed to the following.
compile 'com.android.support.constraint:constraint-layout:2.0.0-alpha5'
I added the following script in build.gradle(app) under android & I was able to compile.
compileOptions {
sourceCompatibility 1.8
targetCompatibility 1.8
}
Similar issue solved by Reinstalling Android Studio.
i'm try constraint layout dependency update available 1,and plugin gradle alpha-6,it worked

(Old 'channel' links no longer work. Links in this answer have been updated to the new formats, make sure to change your bookmarks if you were using them)
You need to update the version of the gradle tools you are building with. This can be found inside the dependencies section of your build.gradle. You have 3 options you can update to:
The latest stable version referenced in the release channel as of 2nd March, 2017 is
classpath 'com.android.tools.build:gradle:2.3.0'
Or the latest beta version via preview channel as of 15th February, 2017 is
classpath 'com.android.tools.build:gradle:2.3.0-beta4'
And the latest alpha version also from the preview channel as of 21st March, 2017 gives you the option to use
classpath 'com.android.tools.build:gradle:2.4.0-alpha3'
Updating requires you to also upgrade the gradle wrapper. As of 20th February '17, the newest is:
distributionUrl=https\://services.gradle.org/distributions/gradle-3.4-all.zip
On android studio you can find your wrapper by changing to the project view and looking in gradle/wrapper/gradle-wrapper.properties
Sometimes after changing wrapper the project will fail to compile with an error like “Minimum supported Gradle version is 2.14.1. Current version is 2.10. Try changing Gradle distribution version to...” despite already having the correct version in gradle-wrapper.properties. If that happens try the following:
Go to Settings > Build, Execution, Deployment > Gradle
Under Project-level settings ensure that Use default gradle wrapper (recommended) is the selected option, then re-build your project.
(Additional Note: With regards to the alpha and beta versions - there is not always a newer build than the stable version when I check, in those cases I've just given values for the previous version. This allows you to roll back to that version if you experience issues with the released version)
In new project change this part:
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
with
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'.
If you're not experienced user, please stick with Android Studio's Updates Stable Channel. I suppose you got Android Studio from Canary Channel.
Note that:
The Canary Channel for Android Studio delivers the bleeding edge updates on a roughly weekly basis. While these builds do get tested,
they are still subject to bugs, as we want people to see what's new as
soon as possible.
From: http://tools.android.com/download/studio/canary
You don't need to change dependencies of your older projects. They should run normally on the latest version.
Same problem on update.
this Fixed it for me:[build.gradle]
classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
or
classpath 'com.android.tools.build:gradle:2.0.0-beta2'
Just in Advanced System Settings in Windows Properties, add a new environment variable with the name ANDROID_DAILY_OVERRIDE and the given value in error message. Restart android studio and you will be ready to go
As of April 5, 2016 this worked for me:
classpath 'com.android.tools.build:gradle:2.0.0-rc3'
gradle version you need became
classpath 'com.android.tools.build:gradle:2.0.0-beta7'
Which requires you to use the gradle wrapper for 2.10 if you were still using previous version
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
On android studio you can find your wrapper by changing to the project view and looking in gradle/wrapper/gradle-wrapper.properties
classpath: com.android.tools.build:gradle:+
This will solve the problem by updating gradle to latest one.
However it is dangerous(will code in alpha stage) & will also give warnings.
If you are using Android Studio 2.0 Preview I can suggest using 'beta' updates channel instead of 'stable'. It will allow you to receive latest gradle configuration changes. You can change updates channel in Settings - Appearance & Behavior - System Settings - Updates. Select Automatically check updates for [Beta Channel]
In order to know actual version of gradle classpath and distributionUrl (check Nick Caroso's answer) you can create new empty project and see these values there.
You need to change your gradle-wrapper.properties file in gradle/wrapper folder of your app, change your distributionUrl as this:
distributionUrl=http\://services.gradle.org/distributions/gradle-2.8-all.zip
Use http: or https:\ as per your requirement.
Then just clean your project and you are done!!!
Side Note :
classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
is available now, if you want to use latest version.
Also you can take advantage of instant run feature of android studio using this, which is not available in gradle version below 2.0.0
Android Studio 2.0 has an update project to use instant-run. For those like me with little brains:
http://tools.android.com/tech-docs/instant-run
The current version of Android Studio 2.0 is Beta 6.
try update gradle to 2.10
for mac, tha path is Android Studio > Preferences > Builds,Execution,Deployment > Build Tools > Gradle
of course you must download gradle 2.10 before
I got the same error on 04/07/2016 with
'com.android.tools.build:gradle:2.2.0-alpha2' and gradle wrapper 2.10
then, I just changed to
'com.android.tools.build:gradle:2.2.0-alpha3'
now I have no problems.
Hope this help peple.
I have resolved this way.
Steps:
Open gradle-wrapper.properties file and change distributionUrl to https\://services.gradle.org/distributions/gradle-2.14.1-all.zip.
Open root level build.gradle and change classpath to com.android.tools.build:gradle:2.2.2.
Sync your Android studio project.
Reference screen shot:
Done.
just change
classpath 'com.android.tools.build:gradle:2.0.0-alpha '
or
classpath 'com.android.tools.build:gradle:2.1.0'
I change my classpath from 'com.android.tools.build:gradle:2.2.0-alpha4'
to classpath 'com.android.tools.build:gradle:2.2.0-alpha5'
and clicked "try_again" when the warning appears "unable to find cached classpath" you just click "sync", this worked like a breeze.
This problem occures generally when the IDE(android studio) in which project is build and the project are not in compatible gradle plug in. Please check the link below
http://tools.android.com/tech-docs/new-build-system/version-compatibility
In my case i had created a project using AS 1.0/2.0 version, and later imported in studio version new it gave me error then I opened project in older version of AS it worked.

File -> Project Structure -> Project -> Android Plugin version = 2.2.3
Working fine of Android Studio 2.2.3

Execution failed for task ':app:compileDebugAidl': aidl is missing

I installed Android Studio on my computer. I created a new project but that got me the error below. What can I do?
Error:Execution failed for task ':app:compileDebugAidl'.
> aidl is missing
My Android Studio version is 1.1.0.
This is my build.gradle file:
buildscript {
repositories {
jcenter()
}
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
}
}
allprojects {
repositories {
jcenter()
}
}
And :
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "24.1.2"
defaultConfig {
applicationId "com.example.jo.cloning_a_login_screen"
minSdkVersion 13
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-v7:22.0.0'
}
In my case I downloaded version 22 of Android M and Android 5.1.1 using Android Studio 1.2.1.1 but when I try to do a Hello World this same error showed me
So the solution for me was doing right click in app like the image below and choose "Open Module Settings"
then there you have 2 options. I've changed both with the last version I had.
Compile SDK version to API 21 Lollipop
and Build Tools Version to 21.1.2
Finally clean the project and Build
UPDATED
TO Get Android Studio 1.3 follow these steps
Open the Settings window by choosing File > Settings.
Choose the Appearance & Behavior > System Settings > Updates panel.
On the Updates panel, choose the option Automatically check updates for: Canary Chanel.
On the Updates panel, select Check Now to check for the latest canary build. Download and install the build when you are prompted.
Then you'll have something like this to update your Androud Studio to 1.3 and with this you can test Android M
Update: Real Cause
This bug happens when the versions of SDK, Build Tools and Gradle Plugins doesn't match (in terms of compatibility). The solution is to verify whether you are using the latest version of them or not. The gradle plugins are placed in the build.gradle of the project, and the other versions are on the build.gradle of the module. For example, for SDK 23, you must use the Build Tools 23.0.1 and gradle plugins version 1.3.1.
It has been fixed two days ago, so you can use:
buildToolsVersion '23.0.0 rc2'
with the newest android gradle plugin:
classpath 'com.android.tools.build:gradle:1.3.0-beta2'
Note:
I had some weird problems with gradle 2.4 distribution, but trying to build the project again has fixed that for me.
EDIT
There is a newer version of build-tools 23, so you should probably use:
buildToolsVersion '23.0.0 rc3'
EDIT 2
And yet again, there are newer version of both gradle plugin and build-tools, so you can switch to using:
classpath 'com.android.tools.build:gradle:1.3.0'
and
buildToolsVersion '23.0.0'
I had a similar error with a fresh install of Android Studio 1.2.1.1 attempting to build a new blank app for API 22: Android 5.1 (Lollipop).
I fixed it by simply changing the Build Tools Version from "23.0.0 rc1" to "22.0.1" and then rebuilding.
On Windows, F4 opens the Project Structure and the Build Tools Version can be set in the Modules > app section:
I think all this does is change the setting in the build.gradle file in the app but I didn't want to change that manually just in case it does something more.
I tried to uninstall/install and it did not work. I am running OSX 10.10.3 with Android Studio 1.2.1.1 on JDK 1.8.0_45-b14 and the solution I found to work is similar to Jorge Casariego's recommendation. Basically, out of the box you get a build error for a missing 'aidl' module so simply changing the Build Tools Version to not be version 23.0.0 rc1 will solve your problem. It appears to have a bug.
UPDATE
After commenting on an Android issue on their tracker (https://code.google.com/p/android/issues/detail?id=175080) a project member from the Android Tools group commented that to use the Build Tools Version 23.0.0 rc1 you need to be using Android Gradle Plugin 1.3.0-beta1 (Android Studio comes configured with 1.2.3). He also noted (read the issue comments) that the IDE should have given an notification that you need to do this to make it work. For me I have not seen a notification and I've requested clarification from that project member. Nonetheless his guidance solved the issue perfectly so read on.
Solution: Open your build.gradle for your Project (not Module). Find the line classpath com.android.tools.build:gradle:xxx under dependencies where xxx is the Gradle Plugin version and make the update. Save and Rebuild your project. Here is the Android Gradle docs for managing your Gradle versions: https://developer.android.com/tools/revisions/gradle-plugin.html
I was able to get build to work with Build Tools 23.0.0 rc1 if I also opened the project level build.gradle file and set the version of the android build plugin to 1.3.0-beta1. Also, I'm tracking the canary and preview builds and just updated a few seconds before, so perhaps that helped.
// 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-beta1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
Quick fix that worked for me:
Right click on project->"Open Module Settings"->Build Tools Version change to: 22.0.1
To build your application without aidl is missing error with compileSdkVersion 23 and buildToolsVersion "23.0.1" you should specify latest versions for Android Gradle plugin (and Google Play Services Gradle plugin if you are using it) in main build.gradle file:
buildscript {
repositories {
...
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.1'
classpath 'com.google.gms:google-services:1.3.1'
}
}
I had the same error i fixed it by going to the build.gradle (Module: app) and changed this line from :
buildToolsVersion "23.0.0 rc1"
to :
buildToolsVersion "22.0.1"
You will need to go the SDK Manager and check if you have the 22.0.1 build tools. If not, you can use the right build tools but avoid the 23.0.0 rc1.
Essentially Matt Daley/Johnny Mohseni's solution worked for me.
I faced exactly the same problem on a fresh Android Studio V 1.2.1.1 installation. I created a new project (blank activity) and straightaway god this build error.
Error:Execution failed for task ':app:compileDebugAidl'.
> aidl is missing
As suggested, changing the gradle dependency from 1.2.3 to 1.3.0-beta1 fixed it.
classpath 'com.android.tools.build:gradle:1.3.0-beta1' // <--- WORKS!
//classpath 'com.android.tools.build:gradle:1.2.3' // <--- default - failed
Once 1.3.0-beta1 change was saved, I got a prompt to upgrade dependencies. Upon accepting the request to upgrade, the gradle build status bar at the bottom tracked the packages being synced. When that completed, the build was automatically triggered and completed successfully.
Use your file browser and copy-paste the IInAppBillingService.aidl into /app/src/main/aidl/com/android/vending/billing/
The problem was actually in the version Android Studio 1.3 updated from the canary channel. I updated my studio to 1.3 and got the same error but reverting back to studio 1.2.1 made my project run fine.
buildtools layout in 23.0.0.rc2 was reverted
so to be able to use it, you need to upgrade the plugin to 1.3.0-beta2 or higher as i show below:
I am working with sdk 23.1.0 and gradle 1.3.1. I created a new project edited nothing and got the aidl error. I went into my project gradle file and changed tool to 22.0.1 instead of 23.1.0 and it worked:
compileSdkVersion 23
buildToolsVersion "22.0.1" //"23.1.0"
Check if you actually have installed the buildVersionTools you are using. In my case I tried 25.0.1 whilst I only had 25.0.2.
To check it go to the SDK Manager, clicking the icon:
Then click Launch Standalone SDK Manager at the bottom:
Now check whatever you need and install packages.
Hope it helps!
