java.lang.RuntimeException: 无法启动活动组件信息的活动

Question

我正在开发一个应用程序，需要创建一个农历日历。我正在创建一个自定义的农历日历。目前关于农历日历的代码非常有限，但是我还是设法创建了一个。以下是我的代码：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        webView = (WebView)this.findViewById(R.id.wv);
         webView.loadUrl(contentUri);
       // webView.loadUrl("file://D:/Andro_WS_2/LunarCalendar/assets/calendar.html");

        mGestureDetector = new GestureDetector(this);
        webView.setOnTouchListener(this);
        try {
            Thread.sleep(1500);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }                  

        webView.loadUrl("javascript:pushBtm('MU')");  
        webView.loadUrl("javascript:pushBtm('MD')"); 

        if(!ConfigCenter.getValue(this, Constant.KEY_WIDGET_ADDED, false)){ 
                Toast.makeText(MainActivity.this, "Please Wait", Toast.LENGTH_LONG).show();
        }

    }

当我运行这段代码时，它会崩溃。我的错误日志(Logcat)显示：

我的XML是：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:umadsdk="http://schemas.android.com/apk/res/com.china.calendar"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/white"
    android:orientation="vertical" >

    <WebView
        android:id="@+id/wv"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

    <net.youmi.android.AdView

        android:layout_width="fill_parent"

        android:layout_alignParentBottom="true" />

</RelativeLayout>

你是否已经将广告库添加到项目的libs文件夹中？ - GrIsHu

请发布您的清单文件代码或检查您是否在清单中添加了以下行：<activity android:name="com.google.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />。 - GrIsHu

是的Grishu，我已经添加了这个库。 - Prinkal

第44行：setContentView(R.layout.main); - Prinkal

我已经从我的XML和代码中移除了AdView，现在它正在工作。我正在从Assets中获取一个HTML文件，当我运行它时，我的AVD显示“该网页（文件地址）可能暂时下线或已永久移至新的网址。”请问有谁可以告诉我为什么会出现这个错误？ - Prinkal

我认为你应该在布局文件中更改adview类。

除了将adview定义为net.youmi.android.AdView，尝试在布局中将其定义为com.google.ads.AdView。

按照以下方式添加AdView：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" <!-- Change this line also -->
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/white"
    android:orientation="vertical" >

    <WebView
        android:id="@+id/wv"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

    <com.google.ads.AdView
        android:id="@+id/ad"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="your add id" />

</RelativeLayout>
