我已阅读，问题出在清单中的活动，这是我的阶级和清单 类
I have read that the problem is with the activity on the manifest and here is my class and the manifest class
package com.georgepanayi.mixfmcyprus.radio;
import org.holoeverywhere.app.Activity;
import android.os.Bundle;
public class Main_Activity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mix_fm__main);
}
}
清单
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.georgepanayi.mixfmcyprus.radio"
android:versionCode="1"
android:versionName="1.0" >

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

</manifest>
另外，我使用的库，如Holoeverywhere，SherlockActionBar 4.3.1和2.4.1 ViewPagerIndicator
Also I'm using libraries like Holoeverywhere, SherlockActionBar 4.3.1 and ViewPagerIndicator 2.4.1
任何人能发现问题？
感谢您
解决方案：
这个问题是与Holoeverywhere。我已经为解决这一问题做的是去我的项目的属性 - > Java构建路径 - >订单和出口，然后选择该选项Android的私人图书馆。然后我已经添加了android：名字=org.holoeverywhere.app.Application清单中的标记中
The problem was with the Holoeverywhere. what I have done in order to solve the problem was to go to the properties of my project -> Java build path -> order and export and then select the option android private libraries. then i have added the android:name="org.holoeverywhere.app.Application" inside of the tag in the manifest.
