什麼是錯誤？ – Tushar

catlog顯示「無法啓動活動」，我正在使用實際設備。 – KaSiris

您是否將該活動置於manifest.xml文件中？ – Tushar

您需要添加：

android:name="android.app.Application"

到application標籤在AndroidManifest.xml。

這是因爲您有ClassCastException。參見：android classcastexception on activity startup

這已經存在了。 – KaSiris

我在您發佈的清單中沒有看到它。你必須把它放在應用程序標籤中，而不是活動標籤。 – Tushar

這是一個單獨的活動......寫這個清單的正確方法是什麼？ – KaSiris
