Question

我已经构建了一个名为EverestNewsApp的与RSS Feed相关的Android应用程序，以便显示当前新闻和头条新闻，但毕竟我收到了错误，但应用程序很遗憾地停止了。你能不能看看下面的日志cat错误，并告诉我我犯了什么错误...提前感谢

Answer 1

java.lang.ClassNotFoundException：com.wfwf.everestnewsapp.SplashActivity：这个错误基本上都显示了编译器无法实例化您的SplashActivity.java

确保您已在AndroidManifest.xml中定义了SplashActivity类

Answer 2

您的Android清单需要看起来像这样

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">
    ....

    ....
    <activity
            android:name="com.wfwf.everestnewsapp.SplashActivity"
            android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
</application>

确保条目在您的清单中，否则您将获得classnotfound异常

不幸的是，Android应用停止了工作
