Question

我终于完成了我的应用程序，一切正常。我回去添加admob的东西，现在它不会在模拟器中启动。它说它成功地在模拟器上安装了应用程序，但它没有启动，并且尝试手动运行时图标不可见。我认为清单是我的错误所在，但我不确定。

Answer 1

您的主要活动名称似乎不正确。 Java区分大小写，您的应用程序包名称为

package="com.androidsleepmachine.gamble"

，而您的主要活动类名称为

com.AndroidSleepMachine.gamble.HOME

抛出ClassNotFoundException，因为清单中的Activity类名称不正确，并且类加载器找不到它。

Answer 2

找不到名为：

的班级

com.AndroidSleepMachine.gamble.HOME

为什么“AndroidSleepMachine”使用大写字母？

为什么不使用：

机器人：名称= “HOME”

...如果你的班级确实叫做HOME.java？ 区分大小写可能会导致您的问题。

com.AndroidSleepMachine.gamble.HOME与com.androidsleepmachine.gamble.HOME

不同
