谷歌地图只显示一个棕色的屏幕和缩放

问题描述

我想在我的Andr​​oid应用程序中显示谷歌地图应用程序：

I want to display google maps app in my android application:

我一样在Android开发者提到的步骤：

I did the steps as mentioned in android developer: https://developers.google.com/maps/documentation/android/start

然而，它在我的应用程序显示对我来说，变焦棕色屏幕（加号和减号按钮）未经地图本身（它不给我任何错误）

However it display for me in my app , a brown screen with zoom (plus and minus buttons) without the map itself (it doesnt show me any error)

我创造了这个XML文件：

I created this xml file:

<?xml version="1.0" encoding="utf-8"?>


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >



    <ImageView
        android:id="@+id/itemImage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:src="@drawable/logo" />

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="400dp"
        android:layout_marginTop="10dp"
        android:layout_weight="66496.79"
        android:orientation="horizontal" >


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


    </RelativeLayout>

</LinearLayout>

这是我的清单文件：

And this is my manifest file:

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

推荐答案

更改此：

<permission
    android:name="com.vogella.android.locationapi.maps.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

到

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

我不知道这是否会帮助，但这个布局code我用最后一个项目
（注意：不同的片段级）

I'm not sure if this will help but this is layout code I used last project(note different fragment class)

<fragment
    android:id="@+id/map_fragment"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    class="com.google.android.gms.maps.SupportMapFragment"
    map:mapType="normal"
            map:cameraTargetLat="@string/default_map_lat"
            map:cameraTargetLng="@string/default_map_lng"
            map:cameraZoom="8">
</fragment>
