由于某些原因,这对xml是不可见的,并且应用程序崩溃了。 我该怎么做才能解决它?
的manifest.xml
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map_holder"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.google.android.maps.MapView -----> do not recognize this
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:apiKey="my_key"
/>
</LinearLayout>
这是我得到的例外!
致命的例外:主要

我该如何解决?
答案 0 :(得分:0)
正确使用的课程是:
com.google.android.maps.MapView
答案 1 :(得分:0)
您是否在<uses-library android:name="com.google.android.maps"/>
文件中添加了AndroidManifest
,并使用 Google API Android SDK 来构建项目,并在AndroidManifest中添加<uses-permission android:name="android.permission.INTERNET"/>
以获取互联网权限
