在android eclipse中意外停止

有人可以幫我嗎？我想在我的android屏幕上顯示地圖，但是當我嘗試運行我的模擬器時，出現錯誤：「意外停止，請重試」。我使用日食。這裏是我的日誌：在android eclipse中意外停止

你能列出你在得到這個錯誤之前完成的步驟嗎？ – bfontaine 2014-10-03 12:52:55

嘗試在您的設備而不是模擬器有時它可以與設備正常工作。

像日誌說，有連接在MainActivity的錯誤，因此從那裏一些代碼可能是有用的

檢查你的日誌，它說這個，

Didn't find class "com.formation.gmaps.MainActivity" on path: /data/app/com.formation.gmaps-1.apk

So please check your package com.formation.gmaps ,does it contains this MainaActivity and check your manifests also to confirm that

非常感謝你很多爲你的答案！是的！我的包com.formation.gmaps包含此MainActivity這裏是我androidManifest：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.formation.gmaps" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="14" 
     android:targetSdkVersion="20" /> 

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 

    <application 
     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <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> 
    </application> 

</manifest>

我的MainActivity：

package com.formation.gmaps; 


import android.os.Bundle; 
import android.os.Environment; 

import java.io.File; 
import org.mapsforge.android.maps.MapActivity; 
import org.mapsforge.android.maps.MapView; 

@SuppressWarnings("unused") 
public class MainActivity extends MapActivity { 


    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     MapView mapView = new MapView(this); 
     mapView.setClickable(true); 
     mapView.setBuiltInZoomControls(true); 
     mapView.setMapFile(Environment.getExternalStorageDirectory().getAbsolutePath() 
       + "/map.map"); 
     setContentView(mapView); 
    } 
}

所以我應該得到一個新的包或？
