首先,我正在使用Eclipse IDE。我试图建立一个应用商店。我不知道发生了什么,但是以前曾奏效,现在我在LogCat中收到此错误。

PS:我注意到我开始活动与其他人有所不同。只是为了让您知道我正在从newboston教程中学习。我希望这不是问题。如果需要,我可以发布GameName类。
编辑:已经解决了这个问题,所以不要浪费您的时间来帮助:)
最佳答案
GAMENAME的实际包是com.servetech.appstore.GAMENAME
而不是com.example.appstore.GAMENAME
。这就是Android无法找到活动的原因。
android.content.ActivityNotFound异常:找不到用于处理Intent的活动
所以
Intent myIntent = new Intent("com.example.appstore.GAMENAME");
至
Intent myIntent = new Intent("com.servetech.appstore.GAMENAME");
