UnsupportedMethodException Android Studio 2.2

Question

I updated my android studio to 2.2.Now when I open and run previous project I got error UnsupportedMethodException.

Unsupported method: AndroidProject.getPluginGeneration().
             The version of Gradle you connect to does not support that method.
             To resolve the problem you can change/upgrade the target version of Gradle you connect to.
             Alternatively, you can ignore this exception and read other information from the model

.

Answer 1

Here are some solutions for your problem. Disabling Instant run should be enough

Gradle version:

Go to your build.gradle file and change gradle-plugin version to:

dependencies {
    classpath 'com.android.tools.build:gradle:2.2.0'
}

Instant Run

It is caused by Android Studio checking availability of the Instant Run feature.

Fix it by disabling Instant Run. Go to:

File -> Settings -> Build, Execution, Deployment -> Instant Run.

and uncheck all positions

Using android-apt plugin

This problem may be caused also by using this plugin.

I suppose for this example that you're using Butterknife library.....

NOTE: If you are using the new Jack compiler with version 2.2.0 or newer, you do not need the 'android-apt' plugin and can instead replace apt with annotationProcessor when declaring the compiler dependency.

Go to your build.gradle file and remove:

classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

Then go to your app/build.gradle file and remove:

apply plugin: 'android-apt'

Then in the same file, replace existing:

apt 'com.jakewharton:butterknife-compiler:8.4.0'

with

annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'

It should work now

Answer 2

You are trying to import a gradle project built with a version not suppoted in your ide(Android Studio), try to rebuild your project with a compatible version from the command line first:

gradle wrapper --gradle-version 3.0

(3.0 is just an example, try to find out what version needs your IDE).

After this step the import process should be ok

Answer 3

Update Gradle version to a higher version for me it starts working when I updated it to 2.10
