Question

我已经解决了许多教程，做了所有事情但没有出现地图我总是最终得到地图的缩放控制视图，我认为清单存在问题

我的代码如下所示

清单：

 <application android:icon="@drawable/logo" android:label="@string/app_name" >
        <activity android:name=".Main" android:noHistory="true"
                  android:label="@string/app_name" >

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

    <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="my api key"/>

    <activity android:name="Activity2" android:label="@string/app_name" android:configChanges="keyboardHidden|orientation" />   


    </application>

    <uses-sdk android:minSdkVersion="9"   android:targetSdkVersion="10" />


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

    <uses-permission android:name="my_package_name.permission.MAPS_RECEIVE"/>
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.CLEAR_APP_USER_DATA" />
    <uses-permission android:name="android.permission.CLEAR_APP_CACHE" />
    <uses-permission android:name="android.permission.SEND_SMS" />
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <uses-permission android:name="android.permission.WRITE_SMS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.READ_LOGS" />

我的mapview.xml是

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <fragment
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:id="@+id/map"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

我的主要活动类

public class Main extends FragmentActivity  {

      private String sResponse;
      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);
        try{
        setContentView(R.layout.mapview);

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

        LatLng sydney = new LatLng(-33.867, 151.206);

        map.setMyLocationEnabled(true);
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 13));

        map.addMarker(new MarkerOptions()
                .title("Sydney")
                .snippet("The most populous city in Australia.")
                .position(sydney));
        }
        catch(Exception ex){

        }
     }

我不知道有什么问题，我还从SDK导入了支持库google-play-service_lib到项目中有谁能告诉我哪里出错了提前致谢！

修改

当我在清单

中添加此权限时

<permission
        android:name="my_package_name.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

它给了我错误

Installation error: INSTALL_PARSE_FAILED_MANIFEST_MALFORMED
Please check logcat output for more details.
Launch canceled!

任何帮助..？

Answer 1

    <meta-data android:name="com.google.android.maps.v2.API_KEY" 
android:value="my api key"/>

用这样的api键替换“my api key”

<meta-data android:name="com.google.android.maps.v2.API_KEY" 
   android:value="AIzaSyAS-3h00tgAf9nSCrwgI02DZ9zMyaIhQQY"/>

从这里获取api密钥https://code.google.com/apis/console/

Answer 2

检查您的清单，正如您提到的目标为10，增加了像这样的targetSDK版本

<uses-sdk android:minSdkVersion="8"   
 android:targetSdkVersion="17" />

使用片段未在API级别9到17中显示的地图
