android - 谷歌地图 V2 错误

Question

所以我的主屏幕上有一个按钮，单击该按钮会将用户带到 map View 。但是，每次我点击它时，应用程序都会崩溃。

我在 4.1.1 上从我的 GS3 运行它

map_screen.xml:

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

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

</RelativeLayout>

MapScreenActivity.java

package com.example.poopify;
import android.app.Activity;
import android.os.Bundle;

public class MapScreenActivity extends Activity  {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_screen);
    }


}

然后是我的 manifest.xml

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

    <uses-sdk
        android:minSdkVersion="9"
        android:targetSdkVersion="14" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="com.example.poopify.permission.MAPS_RECEIVE"/>
    <uses-feature
           android:glEsVersion="0x00020000"
           android:required="true"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyBUIxDObzLKAfFrg04tPc78LBU1zkzZi6w" />
        <activity
            android:name="com.example.poopify.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>
        <activity android:name="com.example.poopify.MainScreen" >
        </activity>
        <activity
            android:name="com.example.poopify.MapScreenActivity"
            android:label="@string/title_activity_map_screen" >
        </activity>

    </application>



</manifest>

这是我的 logcat，但我不知道该怎么做:

Answer 1

它对我也有用..你所要做的就是在下面有两个元数据标签链接:

<meta-data
                android:name="com.google.android.maps.v2.API_KEY"
                android:value="yourGoogleAPIKeyHere" />
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
