我遵循了一些教程,但发现此错误尚未解决。
这是我的代码。 2秒后每次运行,我的应用程序都意外停止(预设计时器)
错误是:应用程序Test(process com.juicy.test)已意外停止。请再试一遍。它在AVD上提示。

最佳答案
在清单文件中,您一次要启动两个活动,因此请从.MainActivity或.Tree活动。中删除此代码。
<intent-filter>
<action android:name="com.juicy.test.MAINACTIVITY" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
希望这可以帮助 ...
