应用程序已停止!谷歌API V2 -地图

Question

我已经按照youtube上的说明创建了一个地图/位置应用程序。我的第一步只是显示地图，但我被卡住了，因为"不幸的是，MyLocApp已经停止了"。我的准则被遵守了。我做错了什么?

清单:

<manifest xmlns:android="http://schemas.android.com/apk/res/android":
        package="tri.mylocapp"
        android:versionCode="1"
        android:versionName="1.0">
    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="14" />
    <permission 
        android:name="tri.mylocapp.permission.MAPS_RECEIVE"
        android:protectionLevel="signature"
       />
    <uses-permission android:name="tri.mylocapp.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"/>
    <!-- The following two permissions are not required to use
     Google Maps Android API v2, but are recommended. -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <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="AIzaSyDZIavpm2Kcj4QXnb01qxoZqiEXTBXTABw"/>
        <activity
        android:name="tri.mylocapp.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>
    </application>
</manifest>

这是布局xml:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

这是proguard-project.txt:

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

这是MainActivity.java:

package tri.mylocapp;
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

你的日志上清楚地写着

.818: E/AndroidRuntime(639): Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 4242000 but found 0.

将Google Play服务版本添加到应用程序的清单

编辑应用程序的AndroidManifest.xml文件，并添加元素中的下列声明。的版本

应用编译时使用的Google Play服务。

您需要将<application>标签下的<meta-data>添加到AndroidManifest.xml

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

这是因为最新的google play服务需要一个版本名，这是在AndroidManifest.xml中使用<meta-data .. />来提到的

构建您的manifest.xml如下:

 ....<application>
..............
<meta-data
    android:name="com.google.android.maps.v2.API_KEY"
    android:value="AIzaSyDrcKDGxUgl0Ps4u2ptOsIUCI6ooXmZ0RU" />
 <meta-data android:name="com.google.android.gms.version"  
 android:value="@integer/google_play_services_version" />
 </application>

Answer 2

在manifest中的activity声明中将locap改为locapp
