java.lang.ClassNotFoundException : com. game.mrnom.MrNomGame 加载器 dalvik.system.PathClassLoader [/data/app/com.game.mrnom-1.apk]

Question

在我的标题中，MrNomGame 是 com.game.mrnom 文件夹(src 文件夹)中的一个 java 文件。
当我运行我的应用程序时，Android 模拟器出现错误:应用程序意外停止。 当我查看logCat时，有很多错误。上面的错误是 logCat 的第一行之一，直接告诉我的错误。 这也是我的 list 文件:

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

    <uses-sdk android:minSdkVersion="8" />

    <application

        android:debuggable="true" 
        android:icon="@drawable/icon"
        android:label="Mr.Nom" >


        <activity
            android:label="Mr.Nom Own"
            android:name="com.game.mrnom.MrNomGame"
            android:screenOrientation="portrait"
            android:configChanges="keyboard|keyboardHidden|orientation" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>


    </application>

    <uses-permission android:name="android.permission.WAKE_LOCK"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-sdk android:targetSdkVersion="8" android:minSdkVersion="8"/>

</manifest>

我用谷歌搜索，有人说当我重构时出现 ADB 错误:重命名一个包(我有时也试过这个)。但我仍然无法修复它。

请帮我解决这个错误。

谢谢:)

这是我的错误日志:

Answer 1

你应该说 list 中的错误

<activity
            android:label="Mr.Nom Own"
            android:name=".MrNomOwn" <<<same name of your activity (case sensitive)
            android:screenOrientation="portrait"
            android:configChanges="keyboard|keyboardHidden|orientation" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

编辑: 您需要像这样将构造函数放入 MrNomOwn Activity 中:

public MrNomOwn(){

super();

}
