Question

我正在使用SupportMapFragment，并且在我测试过的每台设备上都运行良好。我收到了一个java.io.FileNotFoundException的错误报告，其中包含以下内容：

这是我的主要活动xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

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

</LinearLayout>

到底能造成什么？据我所知，绝大多数用户没有遇到这种情况，我想不出任何方法可以尝试复制它。

Answer 1

我建议你这样做：

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

不是android：name。如果有效，请告诉我。

Answer 2

尝试以下方法，它对我有用：

<application>    
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="API KEY" />
    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
</application>

Answer 3

这是解决方案！ NullPointerException from Google maps 如果没有内置卡，请插入SD卡！自2013年以来，谷歌一直没有解决这个问题。

Answer 4

在您的主要活动xml上，更改android:name="com.google.android.gms.maps.SupportMapFragment"

到此：

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

为SupportMapFragment填充类片段时出错
