我在dalvik.system.PathClassLoader.findClass中的Launcher主題java.lang.ClassNotFoundException上不斷出現此錯誤

Question

以下是開發者控制台的實際錯誤。 我的啟動器主題有一個應用程序，所以用戶可以應用主題，聯系我等...

    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]

這是我的應用程序的Android清單。 我第一次發布時忘記添加它

問題是允許“HelperActivity”將Component設置為0，當用戶嘗試從市場或app抽屜打開應用程序時，它會導致應用程序出錯。 在幫助程序活動中，具有APEX意圖的是，當“HelperActivity”活動不再可訪問時，刪除了Apex兼容性。

這個帖子現在已經回答了。

對於更合適的替代，您可能希望使用SET_COMPONENT_ENABLED標志，但未啟用“KILL_APP”標志，但這是另一種情況。
