Android HelloGoogleMaps教程例外

我正在Android开发者资源页面(http://developer.android.com/resources/tutorials/views/hello-mapview.html)上使用HelloGoogleMaps教程,当我在模拟器上运行应用程序的第1部分(“创建地图活动”)时,我收到了消息“应用程序HelloGoogleMaps(进程com.example)已意外停止。请再试一次。”我很确定我正确地遵循了所有指令,但是我不确定我是否正确设置了我的模拟器环境。任何人都可以帮我弄清楚发生了什么事吗?感谢。

这是logcat的输出:

您好我不确定您是否遇到与我相同的问题,但请确保您的清单中的地图和互联网许可在活动括号内,而不是清单中,即:

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

<activity android:name=".champ" android:label="@string/app_name"

机器人:主题= “@机器人:风格/ Theme.NoTitleBar” &GT;

答案 1 :(得分:1)

以下内容有效(它显示的是地图而不仅仅是网格):

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="ru.studiomobile.example"
  android:versionCode="1"
  android:versionName="1.0">
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET" />
<application android:label="@string/app_name" android:icon="@drawable/icon">
    <activity android:name="HelloMapsActivity"
              android:label="@string/app_name"
              android:theme="@android:style/Theme.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <uses-library android:name="com.google.android.maps" />
</application>
</manifest>

重要的是 你把这些用户权限放在哪里。此外,我怀疑它在添加ACCESS_COARSE_LOCATION后开始工作。

main.xml中

<?xml version="1.0" encoding="utf-8"?>
<com.google.android.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="9AaAaaaA7AAA_9AaAAARottenAAAAkMJD8h084Q"
/>

密钥是通过以下两步程序获得的:

步骤1:

$keytool -list -alias androiddebugkey -keystore ~/.android/debug.keystore -storepass android -keypass android
androiddebugkey, May 5, 2011, PrivateKeyEntry, 
Certificate fingerprint (MD5): 99:99:99:99:99:99:99:99:99:99:99:99:99:99:99:99
第二步:那99:99 ...... 在http://code.google.com/android/maps-api-signup.html给了谷歌 并获得了关键。

如果没有此键,MapView只显示一个网格,但不起作用。

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

public class HelloMapsActivity extends MapActivity
{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);
    }

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

但是......我必须尝试使用​​释放密钥,然后再使用调试密钥再次运行。不知道我改变了什么。也许诀窍是用不同的证书安装它。

我必须添加

E/MapActivity Couldn't get connection factory client

并不意味着有错误。地图可以工作,并且仍会将其打印在日志中。

工作应用程序的日志如下所示:

I/ActivityManager(  110): Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=xx.yy.example/.HelloMapsActivity } from pid 211

答案 2 :(得分:1)

“uses-library”应该在应用程序标记内。 “uses-permission”应该在应用程序标记之外。

答案 3 :(得分:0)

您还需要设置一个使用相同Google API部署目标的新AVD

你做到了吗?
