启用 proguard 时无法使用 Crashlytics 2.6.7 和 io.branch.sdk.android.library:2+ 构建 android gradle？答案

【问题标题】：Couldn't build android gradle with Crashlytics 2.6.7 and io.branch.sdk.android.library:2+ while proguard enable?启用 proguard 时无法使用 Crashlytics 2.6.7 和 io.branch.sdk.android.library:2+ 构建 android gradle？

【问题描述】：

我的 Gradle 设置：

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

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

使用上面的 crashlytics 和 branch.io 尝试在启用 proguard 的情况下构建 gradle。我遇到了错误。

最近几天遇到同样的错误兄弟...找不到解决方案，stackoverflow.com/questions/43094195/…
您是否尝试在 gradle 设置中排除 io.branch 'answers-shim' 模块
是的，但仍然出现错误。实际上，我也在使用 Realm；我是否也必须从其库中排除某些模块？检查我的问题，我已经分享了我的问题的链接。
尝试从 gradle 文件中的 'io.branch' 中排除 'answers-shim' 并为 dagger 和 crashlytics 添加必要的 proguard 条目。
由于这些是警告，您可以在构建 gradle 时添加以下行以忽略这些警告。 -dontwarn com.crashlytics.android.answers.shim.**

标签： android android-proguard branch.io crashlytics-android android-gradle-2.2

【解决方案1】：

由于错误消息表明某些“answers-shim”类重复，一个来自 crashlytics，另一个来自 io.branch 本身，我所做的是排除 io.branch 模块“answers-shim” ' 通过编辑下面的 gradle 文件。

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

将“answer-shim”模块排除到 io.branch.sdk.library gradle 设置中，如上所示。

在您的 proguard 文件中添加以下行以忽略警告：

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