Multiple Dex Files Define Lcom/google/android/gms/internal/zzbqy;

Error:Error converting bytecode to dex: Cause: com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzbqy; this error came in my android chat ap

Solution 1:

Enable Multidex in your app and increase heap size.

e.g build.gradle

android {

compileSdkVersion 23
buildToolsVersion "24.0.2"
defaultConfig {

    minSdkVersion 16
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"

    multiDexEnabled true
}

dexOptions {
    javaMaxHeapSize "4g"
}

dependencies {

compile'com.android.support:multidex:1.0.1'

}

Write below code inside Application tag in your Manifest

android:name="android.support.multidex.MultiDexApplication"

Solution 2:

Make sure that you list your firebase dependencies first as such:

app/build.gradle

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'compile'com.google.firebase:firebase-database:11.0.1'compile'com.android.support:appcompat-v7:26.0.0+'compile'com.android.support:design:26.0.0+'

    // Displaying images
    compile'com.github.bumptech.glide:glide:3.7.0'
}
apply plugin: 'com.google.gms.google-services'
