[android] Run Button is Disabled in Android Studio

I can't click the run button. Does anyone know how to fix it?

If your IDE is in power save mode, then the run button etc. are also disabled.

You can verify this via the file -> power save mode, make sure it is disabled.

It was quite silly for me, I just opened the Run > Run Configurations window everything seemed to be fine there, I didn't change anything, when I closed the window the button was enabled.

Just click the dropdown button on left side of RUN button (in your image the dropdown which is in red box) select 'app' option from that and RUN button will be enabled.

Please refer below screenshot.

Above answer didn't work for me, just do click File -> Invalidate/cache -> Invalidate and Restart.

just to go File -> Sync Project with Gradle files then it solves problem.

When creating the Run Configuration, the dropdown for Module had only <no module> for me. Invoking menu File -> Sync Project with Gradle Files added app to the dropdown for Module. Then the Run button became enabled.

• Select the project view in the android studio.
• Remove all gradle folders.
• Restart the android studio.

This will work.

The issue is happening since the gradle was configured for an android studio in another machine and the files pushed on the git and are using in your studio.

After removing these gradle files and restarting the studio, the studio will generate gradle files for your system. This will solve the issue.

If you are trying to run the Flutter Project in Android Studio, and the run button is disabled then here is the solution

Click on add configuration

and select Flutter and then select the main class in dataentrypoint

I'm using Linux where I had a symlink in my home folder pointing to a folder containing the Android Studio projects. Loading a project using the symlink failed, loading a project from the folder where the symlink is pointing to worked!

The above answer didn't work for me, instead closing the project and restaring the AS IDE worked for me.

I opened the wrong folder.... Verify is your root folder in Android studio has the build.gradle file.

if you're importing an eclipse project to android studio, you'll also encounter the same issue as above. Double Check if grade>app has apply plugin: 'com.android.application' on the top as sometimes android studio imports it as a library.

Build->Clean Project

make the run button enable again in my case

I just clicked on the debug icon and it started working.

You have to reconfigure the FlutterSDK path in Android Studio: Go to Setting -> Language & Frameworks -> Flutter and set the path to Flutter SDK

If you have changed jdk version then go to File->Project Structure->Select SDK Location from left bar->update JDK Location in editbar in right bar.

My solution was to go to that multiselect button, then "Edit Configurations" -> Go to "+" and select the module (in this case it would be an app if you do not have a multiproject -> then apply and OK

for flutter project, if the run button is disabled then you have to

tools>> flutter>> flutter packages get >>enter your flutter sdk path >>finish

This should solve your problem...
