我在 dalvik.system.PathClassLoader.findClass 的启动器主题 java.lang.ClassNotFoundException 上不断收到此错误

Question

以下是来自开发者控制台的实际错误。 我的启动器主题有一个应用程序，因此用户可以应用主题、联系我等...

    java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{bigdx.golauncher.serenity.red/bigdx.golauncher.serenity.red}: java.lang.ClassNotFoundException: bigdx.golauncher.serenity.red in loader dalvik.system.PathClassLoader[/data/app/bigdx.golauncher.serenity.red-1.apk]

这是我的应用程序的 android 清单。第一次发的时候忘记加了

Answer 1

问题是“HelperActivity”被允许将组件设置为 0，当用户尝试从市场或应用程序抽屉打开应用程序时，它会导致应用程序出错。当“HelperActivity”活动不再可访问时，辅助活动中的 APEX 意图也将删除 Apex 兼容性。

这个话题现在已经回答了。

对于更合适的替代品，您可能希望使用未启用“KILL_APP”标志的 SET_COMPONENT_ENABLED 标志，但这是另一种情况。
