我正在尝试将新的Firebase应用内消息传递功能实现到我的Android应用程序中，但是由于任何原因，当我将库添加到gradle时，该应用程序崩溃。
这是我的礼物：
implementation 'com.google.firebase:firebase-inappmessaging-display:17.0.0'
implementation 'com.squareup.picasso:picasso:2.71828'
我在这里给出了poicasso的信息，因为在崩溃日志中我收到了与毕加索有关的错误
这是日志文件：

检查与毕加索第12行有关的行。
让我知道是否需要提供任何东西。
答案 0 :(得分：11)
到目前为止，我已经找到了解决方案，很抱歉这么晚才回答。
In-AppMessaging使用Picasso 2.5.2版进行编程，因此，如果使用最新版本进行编译，它将为您提供：
java.lang.NoClassDefFoundError error.
要修复此问题，您必须降级Gradle的Picasso版本，或像我一样将其删除：
//implementation 'com.squareup.picasso:picasso:2.71828'
由于应用内消息传递库已经集成了Picasso，因此您无需在应用程序的build.gradle中注册它。
您要做的另一件事是，因为您具有新的集成：
Picasso.get()
您必须为实施以下版本2.5.2进行更改：
Picasso.with(context)
我希望这可以解决您的错误，就像我的编译中已解决的一样。
