不幸的是，應用程序已停止？

我已經通過了很多例子，但仍然找不到解決方案。即時通訊新的android開發，所以即時通訊在線基本教程。我也跟着谷歌地圖V2的Android教程不幸的是，應用程序已停止？

mainActivity.java

package com.example.midlandtest; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.Menu; 
import com.google.android.gms.maps.CameraUpdateFactory;

import com.google.android.gms.maps.model.BitmapDescriptorFactory; 
import com.google.android.gms.maps.model.LatLng; 
import com.google.android.gms.maps.model.Marker; 
import com.google.android.gms.maps.model.MarkerOptions; 

public class MainActivity extends Activity { 
static final LatLng HAMBURG = new LatLng(53.558, 9.927); 
static final LatLng KIEL = new LatLng(53.551, 9.993); 
private GoogleMap map; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.main); 
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)) 
    .getMap(); 
Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG) 
    .title("Hamburg")); 
Marker kiel = map.addMarker(new MarkerOptions() 
    .position(KIEL) 
    .title("kiel") 
    .snippet("Kiel is cool") 
    .icon(BitmapDescriptorFactory 
     .fromResource(R.drawable.ic_launcher))); 

    // Move the camera instantly to hamburg with a zoom of 15. 
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15)); 

    // Zoom in, animating the camera. 
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null); 
} 

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

}

main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent" 
android:layout_height="match_parent"

</RelativeLayout>

這是我的logcat日誌。請幫助。

我使用運行4.0.4的Android平板電腦來測試應用程序。我將app目標設置爲google api 4.0.3，因爲我被告知要在不同的教程中使用它。請幫助球員，這是讓我瘋狂的

變化：

<activity 
    android:name="midlandtest.MainActivity" 
    android:label="@string/app_name" >

要

<activity 
    android:name="com.example.midlandtest.MainActivity" 
    android:label="@string/app_name" >

您當前的代碼告訴Android的尋找MainActivity在一個名爲midlandtest包。但是，您的軟件包被稱爲com.example.midlandtest。這會導致您遇到的ClassNotFoundException異常。

仍然不會在平板電腦上加載？得到相同的信息。 – PropK 2013-02-27 20:21:11

@JosephKenny嘗試'項目 - >清潔'，然後卸載並重新安裝應用程序。 – 2013-02-27 20:22:10

你可以發佈新的logcat轉儲嗎？ – 2013-02-27 20:24:28

不幸的是，應用程序已停止？
