Gradle is failing on syncing my project in the new Android Studio 2.0

Question

I have just upgraded (i.e., installed a full new version) my Android Studio from 1.5 to 2.0. The upgrade seemed to go smoothly, but I am having trouble with my project when

Answer 1

Ok, I fixed my issue so I wanted to post how I did it in case somebody else runs into this situation.

I was googling around and found a statement regarding working offline with Android Studio that read:

You can, however you won't be able to use any Gradle dependency. Gradle search into the repositories for dependencies using internet, so if you're completely unable to work online. Try not to include anything in the Gradle files, if you do, you'll have to sync it and it'll fail. Bascially just don't touch Gradle files and you'll be good to go.

So, I looked at my gradle files, specifically the build.gradle for the Project (not for the Module). Once there, I noticed a line:

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

So, I replaced 1.3.0 with 2.0.0 and the project built just fine.

I hope this helps somebody else in the future. Good luck.

Answer 2

I had a similar problem. I was trying to build one of the media samples. I tried to use gradle 2.0.0 as you suggested but it didn't work. Got me on the right track though. gradle 2.1.0, along with deactivating offline mode got it to work.

I got same problem when I downloaded "BackboneExampleApp" source code from guithub Click Here For Code. I have done following process by watching settings of my old projects and found these errors. I resolved both errors, run my app and got errors to upgrade project and finally when I updated then no more problems exist. Just see pictures for help.

build.gradle (Project:BackboneExampleApp-master)-->

dependencies {
    classpath 'com.android.tools.build:gradle:2.3.1'
}

Answer 4

It seems there are multiple reasons for this issue. I fixed it by changing the "Gradle version" and "Android plugin version".

It might be helpful to someone. Go to File->Project Structure. Select Project and update your gradle and android plugin versions.

For those have issues with error message: Learn to configure HTTP settings, below is the solution that worked for me. Am using Android studio 2.3.3:

Go to http://developer.android.com/studio/intro/studio-config.html Step 1: Follow the instructions on: Set up Android studio proxy. Step 2: Follow the instructions on : Android plugin for gradle HTTP proxy setting. You will see proxy settings under : # project wide gradle settings, copy the code there and paste it into the empty space in gradle properties file which is under the build gradle in Android studio. Make sure you are connected to internet while on this process. Wait until the the error disappears.

Step 3: you may see another message pop up stating: some folders may have been missing syn now. Just click on syn now.

I hope this help, thanks all.
