使用基本教程谷歌地图API LOG CAT错误 [英] LOG CAT Error on Google Maps API using basic tutorial

问题描述

我提交了类似的问题在早期更先进的项目，所以我想我会利用谷歌提供的地图API的教程，试图复制我得到的错误简化事情，我也得到了同样的错误！好的和坏的，至少我知道这不是我的项目导致错误。

I submitted an similar question earlier on a more advanced project, so I thought I would simplify things by using the maps API tutorial provided by google to try and replicate the error I was getting, and I get the same error! Good and bad, at least I know it's not my project causing the error.

现在我只需要弄清楚为什么我收到这个错误！我是新来编程，但是我跟着这个教程这里verbatum：

Now I just need to figure out why I am getting this error! I am new to programming but I followed this tutorial here verbatum:

https://developers.google.com/maps/documentation/android/start

这是我收到的错误：

下面是我的简单MainActivity.java

Here is my simple MainActivity.java

package com.example.test;

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);
    }
}

这里是我的简单activity_main.xml中

here is my simple activity_main.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"
    class="com.google.android.gms.maps.SupportMapFragment"
    android:name="com.example.test.MainActivity"/>

下面是我的清单：

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


    <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"/>

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

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

</manifest>

我能想到的唯一的事情就是我的清单文件不正确设置。但是我遵循的指示和Eclipse没有给我就可以了错误。我起来这里武器试图弄清楚这一点。任何帮助将是AP preciated。

The only thing I can think of is that my manifest file is improperly set up. But I followed the instructions and Eclipse didn't give me an error on it. I am up in arms here trying to figure this out. Any help would be appreciated.

推荐答案

把这两样meta标签与您的API密钥....在applicationTag之间。
另外补充许可标签与您在谷歌控制台在AndroidManifest.xml中使用你的包名。

Put both meta tag with your API key....in between applicationTag. Also add permission tag with your package name which you use in Google console in your AndroidManifest.xml.

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

 <uses-permission android:name="com.xyz.permission.MAPS_RECEIVE"/>

 <application
                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="Put Your API Key here"/> 

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

下面扩展

public class MainActivity extends FragmentActivity

这insted的

Insted of this

public class MainActivity extends Activity
