How to update gradle in android studio?

问题

I installed Android Studio 0.1.9. Today I got and update to version 0.2 and of course I updated. After the installation I restarted Android Studio but now I get this message:

Project is using an old version of the Android Gradle plug-in. The minimum supported version is 0.5.0. Please update the version of the dependency \'com.android.tools.build:gradle\'

How do I do that? I can\'t find any update tools for the gradle plugin in android studio.

回答1:

Step 1 (Use default gradle wrapper)

File→Settings→Build, Execution, Deployment→Build Tools→Gradle→Use default Gradle wrapper (recommended)

Step 2 (Select desired gradle version)

File→Project Structure→Project

The following table shows which version of Gradle is compatible with specific version of Android plugin for Gradle:

Latest stable versions you can use with Android Studio 3.5.1 (October 2019):

Android Plugin version: 3.5.1
Gradle version: 5.4.1

This may not be the exact answer for the OP, but is the answer to the Title of the question: How to Update Gradle in Android Studio (AS):

• Get latest version supported by AS: http://www.gradle.org/downloads (Currently 1.9, 1.10 is NOT supported by AS yet)
• Install: Unzip to anywhere like near where AS is installed: C:\Users[username]\gradle-1.9\
• Open AS: File->Settings->Gradle->Service directory path: (Change to folder you set above) ->Click ok. Status on bottom should indicate it's busy & error should be fixed. Might have to restart AS

after release of android studio v 3.0(stable), It will show popup, If gradle update is available

OR

Manually, just change version of gradle in top-level(project-level) build.gradle file to latest,

   buildscript {
      ...
      dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
      }
    }

Open File > Project Structure > Project Tab

Android Studio has built in project structure menu to check and update gradle and plugin used in the current project.

Below Website gives a detailed explanation on how to update gradle and gradle plugin of Android Studio.

Update gradle plugin Android Studio

回答5:

On Mac, open terminal and run the following commands as per instructions:

$ curl -s https://get.sdkman.io | bash

then

$ sdk install gradle 3.0

Once the installation is complete, the terminal would ask whether to set it as a default version so type y and make it the default version.

Now open Android Studio -> Terminal and run the following command

Gradle --version

For those who still have this problem (to example to switch from 2.8.0 to 2.10.0), move to file gradle-wrapper.properties and set distributionUrl like way.

distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip

I changed 2.8.0 to 2.10.0 and dont forget to Sync after

回答7:

Open your root build.gradle file and change Gradle version like this

Old version:

 dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
    } 

New version:

dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }

For Gradle version compatibility see this.

回答9:

Go to File > Settings > Builds,Execution,Deployment > Build Tools > Gradle >Gradle home path

Now, set Use default gradle wrapper and edit Project\gradle\wrapper\gradle-wrapper.properties files field distributionUrl like this

distributionUrl=https://services.gradle.org/distributions/gradle-2.10-all.zip

回答10:

It works for me:

just go to '/home/your-user/.gradle/wrapper/dists/'

delete everything inside of this

It will be replaced by android studio

on terminal run: ionic emulate android

Its all...

回答11:

For me I copied my fonts folder from the assets to the res folder and caused the problem because Android Studio didn't accept capitalized names. I switched to project view mode and deleted it then added it as font resource file by right clicking res folder.

回答12:

Most of the time you can have Android Studio automatically update the Gradle plugin.

If your Gradle plugin version is behind, Instant Run will mostly likely not work. Therefore if you go to the Instant Run settings (Preferences > Build, Execution, Deployment > Instant Run), you'll see an Update project button at the top right (image below). Clicking this will update both the Gradle wrapper and build tools.

回答13:

If your run button is gray. This is how i fixed it.

Go to Run in menu, and then press this:

Then it will run your Emulator, and your run button will become green again and you can use it. That is how i fixed it.
