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

In my case the problem was because of capital letters in some packages.

Answer 2

Check you build.gradle (Module: your app).

All com.google.android.gms libraries must use the exact same version specification (mixing versions can lead to runtime crashes).

For example: If you have com.google.firebase:firebase-ads:9.6.1 and com.google.android.gms:play-services-basement:10.0.1

You have to change the firebase version to: 10.0.1

Answer 3

My project used an external library with heterogeneous Java compatibility versions in my build.gradle files (1.7 and 1.8). I fixed it by using the same version for the lib and for the app project. In my case for both :

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
    }

Answer 4

If you are applying any plugins. Then, in your module Gradle file (usually the app/build.gradle),make sure you add the apply plugin line at the bottom of the file to enable the Gradle plugin.

e.g.

Answer 5

Just restart your AS, then Rebuild your app!

Answer 6

Please add this block inside android in build.gradle

dexOptions { preDexLibraries = false }
