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.too         


        

Answer 1

Before:

compile 'com.google.android.gms:play-services-location:10.0.1'
compile 'com.google.android.gms:play-services-auth:10.0.1'
compile 'com.google.firebase:firebase-database:10.2.0'
compile 'com.google.firebase:firebase-core:10.2.0'
compile 'com.google.firebase:firebase-messaging:10.2.0'

After:

compile 'com.google.android.gms:play-services-location:10.2.0'
compile 'com.google.android.gms:play-services-auth:10.2.0'
compile 'com.google.firebase:firebase-database:10.2.0'
compile 'com.google.firebase:firebase-core:10.2.0'
compile 'com.google.firebase:firebase-messaging:10.2.0'

Finally got resolved.

Answer 2

First, build -> clean project -> rebuild it again.

If its not working, then in your build.gradle, set the multiDexEnabled as true

eg:

defaultConfig {
    applicationId "com.example.myapplication"
    minSdkVersion 21
    targetSdkVersion 27
    multiDexEnabled true
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"
}

Answer 3

For me was very easy. Just add:

//noinspection GradleDependency,GradleCompatible implementation 'com.google.android.gms:play-services-auth:11.0.4'

... and the magic happens.

Answer 4

For some reasons, @ChintanSoni's answer didn't worked. I tried deleting the build folder manually but couldn't delete some files since they were being used by some process. Cleaning and re-building the project didn't help so I opened task manager, selected JAVA(TM) Platform SE binary and pressed on 'End task`.

Then I tried to run the project once again and it started compiling fine.

Answer 5

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 6

Please add this block inside android in build.gradle

dexOptions { preDexLibraries = false }
