谷歌地圖Android碎片崩潰

Question

Hye大家好，我是法國人，所以對我英語不好。 對於我的家庭作業，我必須提出一個應用程序誰顯示我的智能手機的位置在谷歌地圖，但是當我在我的connect.xml中添加片段時，應用程序崩潰：「不幸[app]已停止」

我的Google Play服務很好，！

com.google.android.gms文本：ConfigApi連接成功

我覺得我AndroidManifest也不錯

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

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

<uses-sdk 
    android:minSdkVersion="17" 
    android:targetSdkVersion="22" /> 

<application 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 
    <activity 
     android:name=".Main" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

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

    <meta-data android:name="com.google.android.gms.version" 
     android:value="@integer/google_play_services_version" /> 

    <meta-data

     android:value="AIzaSyDQDHg-zejSDW1UHhPef79kOeAlkkXWwyM" /> 
</application> 

</manifest> 

現在是我的connect.xml

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

    <LinearLayout

     <Button

     <Button

    </LinearLayout> 

    <TextView 
     android:id="@+id/txtPosition"

     android:layout_height="wrap_content" 
     android:text="Large Text"

    <fragment 
     android:id="@+id/map" 
     android:name="com.google.android.gms.maps.MapFragment" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"/> 

</LinearLayout> 

</merge> 

我的連接。 java

    txtPosition = (TextView) findViewById(R.id.txtPosition); 

    GoogleMap googleMap;

} 



@Override

    switch(v.getId()) { 
     case R.id.btnGetCar: 
      c = u.getCarPosition(username,password); 
      Log.i("latitude",""+c.getLatitude()); 
      break; 
     case R.id.btnUpdate: 

      //mettre les latitude longiture 
      if(u.updatePosition(username, password, "", "")){ 
       Log.i("updatePosition","true"); 
      } 
      break; 
    }  
} 

@Override 
protected void onDestroy() { 
    // TODO Auto-generated method stub 
    //map.removeView(this.mMapView); 
    super.onDestroy(); 
} 

}

我有一個Main.java誰做重定向Connect.java

這是我的日誌

謝謝您的幫助！ :)

Answer 1

你給錯了安卓名connect.xml：

代替：不是

GoogleMap googleMap; 
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); 

：

android:name="com.google.android.gms.maps.MapFragment" 

用途：

class="com.google.android.gms.maps.SupportMapFragment" 

在Java文件

使用：

SupportMapFragment supportMapFragment = 
     (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); 
googleMap = supportMapFragment.getMap(); 

Answer 2

擴展與FragmentActivity您的活動類似下面一行：

public class Connect extends FragmentActivity implements OnClickListener { 

Answer 3

只需添加ACESS網絡狀態允許您manifeist。

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

請按照下面的鏈接瞭解更多信息。

Answer 4

這是工作！這是因爲我忘了這個

<permission 
    android:name="com.supinfo.tesas.permission.MAPS_RECEIVE" 
    android:protectionLevel="signature" /> 
<uses-permission android:name="com.supinfo.tesas.permission.MAPS_RECEIVE" /> 

謝謝大家！
