应用程序启动时出现此错误

我收到了主题中显示的许多类型的错误。这些错误似乎是偶然的，我无法重现它们。从堆栈中我可以了解到，我的不同布局资源可能会发生此类错误。XML 的行也各不相同。

谁能解释为什么会发生此错误？我能做些什么来解决这个问题？

应用程序启动时出现此错误我需要帮助

这是 XML 的结果，但是在其他 xml 中会发生此类错误

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

</application>

在 AndroidManifest.xml 的元素中

采用

import android.support.v4.app.Fragment;
YourActivity extends FragmentActivity

代替

import android.app.Fragment;
YourActivity extends Activity

并且请在您的清单文件中添加 API KEY

你应该在你的 AndroidManifest 文件中添加这个标签：

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="your APi key here" />

您的 logcat 显示您尚未API KEY在AndroidManifest文件中添加 a 。

请在您的清单文件中添加 API KEY，如下所示：

<meta-data
    android:name="com.google.android.maps.v2.API_KEY"
    android:value="your APi key here" />

如果您尝试在 Fragment 中显示地图，那么在您的布局文件中您必须编写类名，如下所示：

   <?xml version="1.0" encoding="utf-8"?>
    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:name="com.google.android.gms.maps.SupportMapFragment"/>
