Android Chomecast发送器应用程序:MediaRouteActionProvider [英] Android Chomecast Sender App: MediaRouteActionProvider
问题描述
我在Android上使用Chromecast发送器应用程序时遇到问题.这是我的第二个发件人应用程序，因此，总的来说，我的基础知识有所下降.
I have a problem with a Chromecast sender app for Android. This is my second sender app so, generally speaking, I have the basics down.
什么是对的
当我直接从Eclipse运行该应用程序时，它可以在我的两个测试设备上运行. 当我直接从Android Studio运行该应用程序时，它可以在我的两个测试设备上正常工作.
When I run the app directly from Eclipse, it works on both of my test devices. When I run the app directly from Android Studio, it works on both of my test devices.
问题:
当我同时通过Eclipse和Android Studio生成签名的APK时，该应用在两台设备上均达到播放活动"时便崩溃了.
When I generate a signed APK through BOTH Eclipse and Android Studio, the app crashes when it reaches the "cast activity" on both devices.
logcat错误如下:
The logcat error is as follows:

更新:看来我正在使用它.我禁用了proguard.尽管运行了它，但我仍然想知道为什么会遇到此问题.任何提示将不胜感激.谢谢.
UPDATE: It seems that I have it working. I disabled proguard. Despite having it running, I am still interested in knowing why I encountered the problem. Any tips would be appreciated. Thanks.
推荐答案
在您的proguard文件中添加3行...
add 3 lines to your proguard file ...
-keep class android.support.v13.** { *; }
-keep class android.support.v7.** { *; }
-keep class android.support.v4.** { *; }
将解决所有支持库中找不到类的问题.
will solve class not found issues in all the support libs.
