Google Map v2 在加载时挂起并显示灰屏

Question

我正在尝试在我的模拟器上的子片段中显示 Google 地图。但问题是，当像这样加载地图时，模拟器会随​​着 toast 的持续显示而冻结：

我检查了我的清单文件，重新创建了 API 密钥和 debug.keystore。但它仍然无法正常工作。请告诉我如何解决这个问题。谢谢。

**注意：** 我正在 Genymotion 模拟器 - Galaxy S2 API 10(2.3.7) 上进行测试。 Google play 服务已安装在模拟器上。

Answer 1

如果您创建了 debug.keystore，那么您是否使用相同的密钥库路径导出您的应用程序？

我认为您不必导出您的应用程序..

Please export your app with same keystore which is created ..

我希望你解决了你的问题。

Answer 2

更改您的 map_fragment.xml

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

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >
 <FrameLayout android:id="@+id/map"
   android:layout_width="match_parent"
   android:layout_height="0dp"
   android:layout_weight="1.03"
   android:name="com.google.android.gms.maps.SupportMapFragment" />

</LinearLayout> 

到

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

    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:orientation="vertical" >

     <fragment android:id="@+id/map"
       android:layout_width="match_parent"
       android:layout_height="0dp"
       android:layout_weight="1.03"
       android:name="com.google.android.gms.maps.SupportMapFragment" />

    </LinearLayout>
