Question

我已经按照youtube上的说明创建了地图/位置应用程序。我的第一步只是显示地图，但由于“不幸的是，MyLocApp已经停止”，我陷入困境。我的代码被遵循。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);
    }
}

Answer 1

你的logcat清楚地说了

.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服务版本添加到您应用的广告

编辑应用程序的AndroidManifest.xml文件，然后添加在元素中声明如下。这嵌入了版本使用该应用编译的Google Play服务。

您需要将<meta-data>标记下的<application>添加到AndroidManifest.xml

中

....<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称，使用<meta-data .. />内的AndroidManifest.xml来提及

构建您的 manifest.xml ，例如：

 ....<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>
