Syncing Android Studio project with Gradle files

Question

I was working on a project, and then I got a prompt to update Android Studio. After I did that, I started getting this error when trying to run my app Error

It says

The project may need to be synced with Gradle files

How do I solve this?

EDIT

Starting with Android Studio 3.1, you should go to:

File -> Sync Project with Gradle Files

OLD

Clicking the button 'Sync Project With Gradle Files' should do the trick:

Tools -> Android -> Sync Project with Gradle Files

If that fails, try running 'Rebuild project':

Build -> Rebuild Project

Try running './gradlew clean packageDebug' from the project root. – Jonathon Fry Nov 12 '13 at 15:29

Unfortunately this option does not exist in Android Studio 2.2. – IgorGanapolsky Jun 14 '16 at 21:08
@IgorGanapolsky it still exists for me, i'm running 2.2 preview 3. – Jonathon Fry Jun 15 '16 at 08:42

Works for me too. Android 2.3. Anyone knows what causes this error? I spent at least 1 hour finding out what's wrong with this. – codemax Mar 30 '17 at 14:14
Didn't work for me. Had to move all the necessary files into a new project. I'm using Android Studio 3.0 – CLOUGH Nov 24 '17 at 17:18

Starting with Android Studio 3.1, the menu path is `File -> Sync Project with Gradle Files` – Mateus Gondim Apr 06 '18 at 17:20

File -> Sync Project with Gradle Files DOES NOT EXIST – Pete Alvin Oct 27 '19 at 19:22
For those only using `gradlew` via command line tools run `./gradlew build` – johnborges Aug 25 '21 at 01:06

Old Answer

When trying to run the application, instead of selecting the directory highlighted here in blue enter image description here

I selected the subdirectory instead

enter image description here

and clicked "run".All the issues with Gradle are automatically resolved and the missing apk directory is automatically created.

New Solution

The Sync project with gradle files button disappeared from Android Studio for a while.Its back and you can find it here:

hit the button and wait for the task to complete

I've had this problem after installing the genymotion (another android amulator) plugin. A closer inspection reveled that gradle needs SDK tools version 19.1.0 in order to run (I had 19.0.3 previously).

To fix it, I had to edit build.gradle and under android I changed to: buildToolsVersion 19.1.0

Then I had to rebuild again, and the error was gone.

The gradle versions in android studio and your code is not the same. This is why even after you update the gradle version on android studio, the error still persist.

So, edit the Gradle distribution reference in the gradle/wrapper/gradle-wrapper.properties file:

distributionUrl = https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

I am using Android Studio 4 developing a Fluter/Dart application. There does not seem to be a Sync project with gradle button or file menu item, there is no clean or rebuild either.

I fixed the problem by removing the .idea folder. The suggestion included removing .gradle as well, but it did not exist.

For Flutter, you need to open the Android application in your flutter app in a different Android Studio Window to be able to do anything with gradle. – Ojonugwa Jude Ochalifu Sep 23 '20 at 19:43

I just created the 'apk' directory in my build directory.It doesn't work.What else did you do after creating this directory? – Ojonugwa Jude Ochalifu Nov 12 '13 at 15:23
the second thing i did was searching for the SharedPreferences-debug-unaligned.apk and placing it manualy in the apk folder using windows search in startmenu. – patrick Nov 13 '13 at 07:41
