Android 地图应用程序无法正常工作

Question

我正在制作一个简单的地图应用程序并使用 google map api v2....

最小 sdk 是：android 2.2 froyo api 8 目标sdk是：android 4.4 kitkat api 19 编译平台：android 4.4 kitkat api 19

我按照 youtube 教程完成了所有工作，但仍在执行应用程序时收到一条消息“抱歉，您的应用程序 com.example.margallahillhikedroid 已意外停止”

以下是我的清单文件代码：

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

<application

    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="my api key" />

    <activity
        android:name="com.example.margallahillhikedroid.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>

以下是xml的文件代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

<fragment
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</RelativeLayout>

下面是java文件的代码；

package com.example.margallahillhikedroid;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

以下是LOG cat中的错误：

Answer 1

在SupportMapFragment的xml中你应该写：

class="com.google.android.gms.maps.SupportMapFragment"

代替：

android:name="com.google.android.gms.maps.SupportMapFragment"

另请参阅上面链接文档中发布的示例。你也应该使用 FragmentActivity 而不是 Activity..

Answer 2

我不确定它是否仍未解决，但您应该更新设备上的 Google Play 服务。
