java.lang.RuntimeException：无法启动活动ComponentInfo（程序在启动时崩溃）

Question

我知道这个问题已经被问了好几百次，感觉就像我已经经历过所有这些都没有找到答案。

我一直在回答如何添加标记到Google地图。 How to add overlay in google maps API v2 | Android |

我没有得到任何错误，但是当我运行的应用程序，我得到“程序已停止”和我的logcat得到这些错误：

这是我主要的Java：

package com.googlemaps; 

import com.google.android.gms.maps.CameraUpdateFactory; 
import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.SupportMapFragment; 
import com.google.android.gms.maps.model.BitmapDescriptorFactory; 
import com.google.android.gms.maps.model.LatLng; 
import com.google.android.gms.maps.model.MarkerOptions; 

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.view.Menu; 

public class MapActivity extends FragmentActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_main); 
    LatLng sala = new LatLng(59.918434,16.618195); 

    GoogleMap mMap; 
    mMap = ((SupportMapFragment)(getSupportFragmentManager().findFragmentById(android.R.id.content))).getMap(); 
    mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
    mMap.addMarker(new MarkerOptions() 
      .position(sala) 
      .title("Här ligger sala") 
      .snippet("Detta är sala") 
      .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))); 
    mMap.getUiSettings().setCompassEnabled(true); 
    mMap.getUiSettings().setZoomControlsEnabled(true); 
    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(sala,10)); 


} 

而且这里是我的xml：

<?xml version="1.0" encoding="utf-8"?> 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".MainActivity" > 

<fragment 
    android:id="@+id/map" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    class="com.google.android.gms.maps.supportMapFragment" 

    /> 
</RelativeLayout> 

，也是我的清单：

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

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


    <application 
     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <uses-library android:required="true" 
      android:name="com.google.android.maps" /> 
     <activity 
      android:name="com.go8oglemaps.MapActivity" 
      android:label="@string/app_name" 
      android:screenOrientation="portrait"> 

      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

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

     <!-- adds google API key to manifest --> 
     <meta-data 
      android:name="com.google.android.maps.v2.API_KEY" 
      android:value="AIzaSyDSVPzsvOratkVZoMEKa0sF_GLOtcFI7yg" 
      /> 
    </application> 

    <uses-feature 
     android:glEsVersion="0x00020000" 
     android:required="true" /> 
</manifest> 

Answer 1

您的清单更改了您的MapActivty的名称。 Theres拼写错误。

android:name="com.go8oglemaps.MapActivity" 

Answer 2

setContentView(R.layout.your_xml_file); 

添加super.onCreate（savedInstanceState）之后的上面的行;在你的onCreate（）并更新结果。
