【问题描述】：

我对 android 完全陌生。我对代码的了解非常有限。当我尝试在我的 android 设备上运行该应用程序时，它会出现“不幸的是（应用程序名称）已停止”的消息，请有人告诉我如何解决这个问题

这是我的清单

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.benchaful.newboard"
  android:versionCode="1"
  android:versionName="1.0">


<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name="com.benchaful.newBoard"
              android:label="@string/app_name"
              android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
        <activity android:name="com.google.ads.AdActivity" 
          android:configChanges="keyboard|keyboardHidden|orientation" />
</application>
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

</manifest>

我的主要布局

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

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res/com.benchaful.newboard"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/scrollview1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

        <LinearLayout android:layout_width="fill_parent"
         android:id="@+id/home_layout"
         android:orientation="vertical"
         android:layout_height="wrap_content"
         android:background="#000000"
         >

这里有一些按钮

<WebView 
    android:id="@+id/accesskey"
    android:layout_width="fill_parent"
    android:layout_height="100px"
/>


    </LinearLayout>
</ScrollView>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:ads="http://schemas.android.com/apk/res/com.benchaful.newboard"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:background="#ffffff"
              android:gravity="bottom"
              android:layout_alignParentBottom="true"
              android:layout_alignBottom="@+id/home_layout"
              >

【解决方案1】：

您的活动的全名是什么？你的清单有这个：

<activity android:name="com.benchaful.newBoard" ... >

但是“com.benchaful.newBoard”是你的包名。

【解决方案2】：

在我看来，您将包和类都定义为

com.benchaful.newboard

您在该包中是否有要开始您的主要活动的课程？如果你确实有这门课，看到它也发布会很有帮助。
