未按規定開展活動，由於ClassNotFoundException的

我想使用的代碼，推出新的活動：未按規定開展活動，由於ClassNotFoundException的

Intent i = new Intent(this, TempLobbyActivity.class); 
startActivity(i); 
finish();

當我啓動這個代碼執行的意圖構造時，我得到以下例外。

我已經確定類TempLobbyActivity確實存在並且是一個適當的活動。我沒有得到其他錯誤。

這裏是TempLobbyActivity的開頭：

package com.edr.iveflownthat; 

import android.app.Activity; 
import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentActivity;

import android.support.v7.app.ActionBarDrawerToggle;

public class TempLobbyActivity extends FragmentActivity {

你的'TempLobbyActivity'在哪裏？把你的清單文件。 – Rustam 2014-11-02 17:30:14

運行項目 - >清潔，看看這是否能解決問題。或者重新啓動eclipse。 – Jickson 2014-11-02 17:37:37

在你的問題中包含TempLobbyActivity的開始 - 特別是包聲明和類聲明，顯示你擴展和實現的內容。同時在觀看logcat時卸載並重新安裝與缺失依賴關係有關的消息。 – 2014-11-02 19:10:11

即使在AndroidManifest.xml中定義了類，我也遇到了同樣的錯誤。

原因：有時會發生這種情況，因爲您添加了多個版本的appcompat庫。

解決方案：刪除以前版本的appcompat lib並將appcompat_v7.jar添加到您的/ lib文件夾。

清理您的項目並重新構建。你可能不會再犯錯。

在AndroidManifest.xml中註冊TempLobbyActivity

<activity android:name="TempLobbyActivity"></activity>

所以您的清單文件應該是這樣的

<activity android:name=".MainActivity" 
       android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN"/> 
      <category android:name="android.intent.category.LAUNCHER"/>   
     </intent-filter> 
    </activity> 
<activity android:name="TempLobbyActivity"></activity>

我懷疑這不是問題。但是你發佈的內容不會很有用 - 你必須指定包名或帶「。」。至於MainActivity。 – 2014-11-02 19:08:27

@Reinaldo - 編輯你的答案每克里斯·斯特拉頓的建議，我會upvote你的答案:) – 2014-11-02 19:28:17

對於誰可能仍然面臨這個問題的：

添加適當的依賴關係，你的build.gradle，當依賴性沒有正確添加和gradle這個不能編譯庫添加到項目中發生這樣的錯誤，所以，您不會在運行時訪問這些庫類。

我發現我不得不在控制檯中的錯誤，我忽略了：

[ExoPlayerLib]找不到ExoPlayerLib.apk。

解決這與SO answer，NoClassDefFoundError的次要錯誤也解決了。

看起來，任何與構建和包括項目庫中的問題都可能導致此問題。
