问题描述

我做了一个非常简单的应用程序,只是显示一个谷歌地图。然而,它只是似乎显示灰色方块。

我troubleshooted都做几乎所有我可以。我5+遍检查了我的code,我比起来,甚至到其他教程。我重新做了我的API密钥3倍 - 他们没有工作

我正在使用的手机连接到无线网络。即使是仿真器将无法正常工作。我已经建立了清单中的库和权限。我想我已经做到了这一切,但它仍然无法正常工作...任何建议?

下面是我的code:

MapsActivity.java:

 包net.learn2develop.GoogleMaps;

进口com.google.android.maps.MapActivity;
进口com.google.android.maps.MapView;
进口android.os.Bundle;

公共类MapsActivity扩展MapActivity
{
    / **第一次创建活动时调用。 * /
    @覆盖
    公共无效的onCreate(包savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        的setContentView(R.layout.main);
    }

    @覆盖
    保护的布尔isRouteDisplayed(){
        返回false;
    }
}
 

main.xml中:

 < XML版本=1.0编码=UTF-8&GT?;
< RelativeLayout的的xmlns:机器人=htt​​p://schemas.android.com/apk/res/android
    机器人:layout_width =FILL_PARENT
    机器人:layout_height =FILL_PARENT>

        />

解决方案

但问题是,迈克使用与发布的密钥库,而不是调试密钥库的日食编译APK时使用生成的API密钥。

I've made a very simple app that just displays a Google map. However, it only seems to be displaying gray squares.

I've troubleshooted and have done virtually everything I could. I checked my code 5+ times over, I've compared it even to other tutorials. I've re-made my API key 3 times - none of them work.

The phone I'm using is connected to wireless. Even the emulator won't work. I have the library and permission established in the manifest. I think I've done just about everything, but it still doesn't work... any suggestions?

Here's my code:

MapsActivity.java:

package net.learn2develop.GoogleMaps;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import android.os.Bundle;

public class MapsActivity extends MapActivity 
{    
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }
}

main.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">

    <com.google.android.maps.MapView 
        android:id="@+id/mapView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:enabled="true"
        android:clickable="true"
        android:apiKey="0duU2_tgS67qkUZIpmLVIo0IDvJDh4Ew1Mzh9Pg"
        />
</RelativeLayout>

GoogleMapsManifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="net.learn2develop.GoogleMaps"
      android:versionCode="1"
      android:versionName="1.0.0">
    <uses-sdk android:minSdkVersion="7" />
    <application android:icon="@drawable/icon" android:label="@string/app_name">

    <uses-library android:name="com.google.android.maps" />  

        <activity android:name=".MapsActivity"
                  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>

    <uses-permission android:name="android.permission.INTERNET" />

</manifest>

解决方案

The problem was that Mike was using an API key generated with the release keystore instead of the debug keystore that eclipse uses when compiling the apk.
