Hi @ManuBabu,

Please notice that we do not explicitly support Android.

The information you provide is not enough to understand what is going on. How can you say that this problem is related to google-cloud-translate? Could you please share the full stack trace, and also the warnings you are getting when building the app?

Hi @mziccard ,
i am getting this error, when i add com.google.cloud:google-cloud-translate:0.5.0' in my project,
if i remove this dependency and build again it will removes the errors and warnings also.

@ManuBabu the errors you provided are not enough to understand what's going on, can you share more information?

[ManuBabu]

@mziccard Sure,

i am trying to implement language translate feature in my app, so to implement this feature i am using Gradle Dependency :"com.google.cloud:google-cloud-translate:0.5.0" after syncing the dependencies i am getting following warnings:

@ManuBabu try to include google-cloud-translate while excluding grpc-protobuf-lite, this should get rid of duplicated classes:

compile ('com.google.cloud:google-cloud-translate:0.5.0') {
    exclude group: 'io.grpc', module: 'grpc-protobuf-lite'
}

[ManuBabu]

Hey @mziccard , i tried with the solution you provided, still i'm getting same errors as mentioned in the above comment. i tried the given solution in my project as well as new project. i am getting same error. :(

[ManuBabu]

could you please create fresh sample project and check by adding dependency. so that you can understand the issue better.

[mziccard]

Here you can find a working Android application using google-cloud-translate.
Notable things in the app's build.gradle are:

• Enable multidex:

    defaultConfig {
        ...
        multiDexEnabled true
    }

• Force findbugs resolution strategy:

    configurations.all {
        resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
    }

• Exclude duplicate files:

    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/io.netty.versions.properties'
        exclude 'META-INF/INDEX.LIST'
    }

• Import google-cloud-translate avoiding duplicates:

    compile ('com.google.apis:google-api-services-translate:v2-rev47-1.22.0') {
        exclude group: 'com.google.guava'
    }
    compile ('com.google.cloud:google-cloud-translate:0.5.0') {
        exclude group: 'io.grpc', module: 'grpc-all'
        exclude group: 'com.google.protobuf', module: 'protobuf-java'
        exclude group: 'com.google.api-client', module: 'google-api-client-appengine'
    }

Hope this helps.

[mziccard]

@tiendatit92 Have a look at this example for a working Android app using google-cloud-translate 0.5.0.

[ManuBabu]

@tiendatit92 hi sorry for late reply, i just changed com.google.android.gms:play-services to 9.6.0 version. and added force to it.
