android : Error converting byte to dex

Question

So, I am getting the following error while running the project after upgrading build.gradle (Project) from

dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
}

to

dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
}

I just changed the gradle from 2.0.0-alpha2 to 2.0.0-alpha3 and then, trying to build the project.

Error log:

Answer 1

Thing that worked for me.

1. Go to android folder of your app.
2. Run ./gradlew clean

Answer 2

In my case, I put

apply plugin: 'com.google.gms.google-services'

at the bottom of build.gradle file and set multiDexEnabled true in defaultConfig. Then just run and it works.

Answer 3

In case it helps someone, in my case I was using a custom package in release mode instead of in debug mode.

I just changed the package from "release" to "debug" and it worked.

Answer 4

Okay. I don't know how but this worked.

First I cleaned the project and then, running the project made everything go alright.

Inshort, First Clean and then Run.

Edit First Clean and then Make Project also works.

Answer 5

This problem is mainly in gradle or in misversioned libraries, including, from libraries, when both define the same class. Expand and check, imported external libraries...

You cannot have two same classes to be exported to one place, or code, therefore, dexer does not know which one should be used...

Answer 6

I met the same problem,and i clean project ,some other problems causeed can not clean,so i manually delete dir 'build' ,so it can can clean Ok,then run it ok for me.
