應用程序無法啓動在Android 2.2（Froyo）

我的應用程序一直運行良好，直到最近的Froyo更新。安裝Android 2.2 SDK後，我可以編譯我的代碼而不會出現任何錯誤。然而，當我運行它，它只是強制關閉：應用程序無法啓動在Android 2.2（Froyo）

主STA rtup類是com.handyapps.easymoney.EasyMoney。我在onCreate（）方法的開始處放置了一個斷點，但是我發現它甚至沒有到達那裏。不知何故，該應用程序無法在Android 2.2中加載......但它對於以前的所有Android版本都可以很好地工作。一直試圖找到過去兩天的原因，但我完全難住！

如果您在清單文件中使用android：targetSdkVersion =「8」，它仍然會編譯沒有錯誤嗎？ – 2010-05-23 12:08:45

看到我對你的自我回答評論爲什麼它在'android：name'上失敗。 – 2010-05-28 07:03:34

-1

從ClassCastException：

當程序試圖投一個目的是一類拋出該異常與它是不兼容。

我會通過代碼並檢查我正在執行的演員。

他說它在主要活動中甚至沒有達到onCreate（），所以他應該在代碼中查找哪裏？ – HXCaine 2010-05-23 23:16:48

這實際上是問題所在 - 只是所討論的代碼是清單XML，它將內置啓動代碼設置爲嘗試將不適當的內容無效轉換爲Activity或任何類，以便它可以調用構造函數和onCreate（）方法。 – 2012-05-05 15:20:16

我找到了解決方案！只需要從manifest中的應用程序標記中刪除android:name屬性...但編譯器應該給出警告或錯誤。

大聲笑，我很驚訝它在2.2之前的工作 - 「android：name」期望一個像com.foo.BarApplication或者只是'.BarApplication'這樣的合格的類名。給它一個類似標籤的值，如@ string/app_name，肯定會失敗。 – 2010-05-28 07:02:48

即使它應該失敗，不應該有某種警告而不是某些神祕的例外嗎？爲什麼類名稱屬性在應用程序標籤中被賦予'name'屬性名稱？所以誤導 – 2010-05-29 05:51:04

我試圖找到什麼樣的麻煩將發生與我的應用程序針對Android 1.5（因爲我沒有與Android 2.2的物理設備），並安裝在Froyo設備，我也發現這個例外，IM非常驚訝，我選擇了警告忠告大聲笑，豎起大拇指！ – Jorgesys 2010-06-22 23:25:51

應用程序無法啓動在Android 2.2（Froyo）
