Question

我正在尝试运行Firebase聊天消息示例应用，但是由于基础lib而导致错误。

我在我的申请和推荐链接上使用的下面的库

compile 'com.firebase:firebase-client-android:2.5.2+'

引起：java.lang.RuntimeException：找不到Android类。是你使用firebase-client-android工件？

因为这个版本发生了：

compile 'com.firebase:firebase-client-android:2.5.2+'

您可以使用以下方法之一：

compile 'com.firebase:firebase-client-android:2.4.0'
compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.firebase:firebase-client-android:2.3.0'

希望它能帮到你!!
