ADT更新后出现NoClassDefFound错误

Question

我最近将ADT从22更新到了23.0版。现在，我的项目在更新之前可以正常运行，但出现以下错误：

  01-01 10:19:27.016: E/AndroidRuntime(2405): java.lang.NoClassDefFoundError: com.mapps.dailystatusupdater.StatusUpdate
01-01 10:19:27.016: E/AndroidRuntime(2405):     at com.mapps.dailystatusupdater.SplashScreen$RefreshTokenTask.onPostExecute(SplashScreen.java:253)

SplashScreen.java

private class RefreshTokenTask extends AsyncTask<Void, Void, Void>
    {

        @Override
        protected Void doInBackground(Void... params) 
        {
            // TODO Auto-generated method stub
            /**
             * Check if access token is expired
             * Request new  access token  by passing refresh token 
             */
            // DoInBackground code
        }

        @Override
        protected void onPostExecute(Void result) 
        {
            // TODO Auto-generated method stub
            super.onPostExecute(result);
            Intent i = new Intent(SplashScreen.this, StatusUpdate.class);
            startActivity(i);
            finish();

        }

        @Override
        protected void onPreExecute() {
            // TODO Auto-generated method stub
            super.onPreExecute();
        }

AndroidManifest.java

<activity
            android:name="com.mapps.dailystatusupdater.StatusUpdate"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

我还检查了我的Android库以从导入/导出设置中导出。 我该如何解决？ 谢谢

Answer 1

尝试这样：

Project -> Libs -> Right click on Jar file -> Build Path -> Add to Build Path

和

Project -> Right Click -> Properties -> Java Build Path -> Order and Export -> and Check that library -> OK  -> Clean the Project.

Answer 2

转到Project-> Properties-> Java Build Path-> Order＆Export，并确保为您的项目选中了Android Private Libraries。 清理所有项目

还有一件事-goto android sdk manager确保您已安装android build工具。
