我正在尝试运行 Google Play 游戏服务示例,但这样做时遇到了很多麻烦。
最初,尝试通过 Eclipse 中的“将现有代码导入工作区”打开现有代码项目会导致各种我无法弄清楚的错误。即 R.java 没有构建。我可以通过创建一个空白项目并复制粘贴所有代码和资源文件来解决这个问题。
所以我已经设置了项目,并且我已经引用了google-play-services_lib
and BaseGameUtils
,所以在 MainActivity.java 中没有出现错误,并且它都可以编译和构建,但是布局编辑器不断吐出com.google.android.gms.common.SignInButton
无法实例化。
我从下面的错误中粘贴了完整的堆栈跟踪。我想不出我遗漏的任何东西,Eclipse 中“问题”窗口中唯一的内容是清单的“应明确将 android:allowBackup 设置为 true 或 false”。
