In my title, MrNomGame is a java file in com.game.mrnom folder (of src folder).
When I run my app, Android Emulator error: The application has stopped unexpectedly.
When I view logCat, there are many errors. and above error is one of the first lines of logCat and directly tell about my error.
Here is also my manifest file:

<?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>

I google and someone say that ADB bug when I refactor:rename a package (and I have tried this sometimes). but I still cannot fix it.

Help me about this error,please.

thanks 🙂

    Your error in manifest you should say 

    <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>

    edit :
    you need to put constructor in your MrNomOwn activity as this :

    public MrNomOwn(){

super();

}
