大家好我试图通过Eclipse的Export函数打包一个用Scala编写的简单可执行Jar.

尝试从cmd执行Jar时 java -jar test2.jar

我得到以下......任何想法？谢谢.

几周之后,我看到越来越多的应用程序崩溃,但有以下异常

致命异常:java.lang.NoClassDefFoundError android.os.AsyncTask

这个代码运行了一个月没有任何问题,现在似乎在某些设备上失败(75%android 2.3.x和25%android 4.0.3)当我创建一个扩展AsyncTask的类的新实例时,它失败了.

我从UI线程创建这个类.

如何在SDK中定义该类？

添加compile 'com.android.support:support-v13:21.0.+'后build.gradle,我在构建我的应用程序时遇到了一些冲突,所以我不得不在内部添加multiDexEnabled = true.那些冲突已经消失,但是我为缺少的书法图书馆提供了另一个例外(在打开应用程序时):defaultConfigbuild.gradle

我最新的sdk构建工具版本是22.0.1.以前有人遇到过这个问题吗？

我正在尝试使用Eclipse Indigo和ADT r20使用ActionBarSherlock 4.1构建一个小型示例应用程序.

我创建了一个带有空白活动的新Android项目,将actionbarsherlock.jar复制到libs并在构建路径中引用它.

该应用程序构建成功,但在启动模拟器(使用2.2)或设备(使用4.0.4)时,它崩溃并出现错误:

java.lang.NoClassDefFoundError: com.actionbarsherlock.R$styleable
        at com.actionbarsherlock.view.MenuInflater$MenuState.readItem(MenuInflater.java:328)
        ...

我没有使用proguard.

我已经尝试清理ActionBarSherlock项目,将新jar复制到我的示例项目的libs中,然后清理我的示例项目.

我的MainActivity.java非常简单:

package com.example.lrn;

import com.actionbarsherlock.app.SherlockActivity;
import com.actionbarsherlock.view.Menu;
import android.os.Bundle;

public class MainActivity extends SherlockActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getSupportMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

菜单只有一个项目:

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_settings"
        android:title="@string/menu_settings"
        android:orderInCategory="100"
        android:showAsAction="ifRoom" />
</menu>

AndroidManifest.xml也就像Eclipse创建它一样:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.lrn"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter> …

我在eclipse中打开了运行项目.在意外重启窗口之后,现在当我打开日食时,我看到我的项目标有一个小红十字.现在,当我运行main方法时,我得到了一个java.lang.NoClassDefFoundError.

我已经尝试重启eclipse,Project - > Clean但它没有解决问题.

当我检查项目目录时,在'target'文件夹中没有编译的.class文件.我尝试构建项目,但我无法获取编译的类文件,这是错误的原因.

我该如何解决这个问题？

我正在尝试使用代码启动一个新活动:

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

当我启动此代码时,我在执行Intent构造函数时遇到以下异常.

我试图在片段上实现SwipeRefreshLayout.

我已经解决了它在Activity上实现它,但是当我在Fragment上实现它时:java.lang.NoClassDefFoundError:com ...

有没有人有想法？谢谢!

类似的帖子没有答案/解决方案:刷卡刷新布局 - 找不到类

我的代码:

public class Principal extends Fragment implements OnRefreshListener {
    SwipeRefreshLayout swipeLayout;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.principal, container, false);
