Не удалось построить Android-Gradle с Crashlytics 2.6.7 и io.branch.sdk.android.library:2+ при включенном proguard?

Question

Мои настройки Gradle:

compile('com.crashlytics.sdk.android:crashlytics:2.6.7@aar') {
    transitive = true;
}

compile('io.branch.sdk.android:library:2.+') {
    transitive = true;
}

с вышеупомянутым crashlytics & branch.io попробуйте собрать gradle с включенным proguard. Я получаю ниже ошибки.

Answer 1

Так как сообщение об ошибке указывает на то, что некоторые классы "answers-shim" дублируются, один из них - из crashlytics, а другой - из самого io.branch, то, что я сделал, исключил модуль io.branch "answers-shim" путем редактирования файл Gradle ниже.

compile('io.branch.sdk.android:library:2.+') {
    transitive = true;
    exclude module: 'answers-shim'
}

Исключите модуль answer-shim в настройках градаля io.branch.sdk.library, как показано выше.

После этого в вашем файле proguard добавьте строку ниже, чтобы игнорировать предупреждения:

-dontwarn com.crashlytics.android.answers.shim.**
