"Stopped Unexpectedly" tried 10000 times to fix
===

here is my Main java file, MainActivity.java

    package com.myprojects.schecklist;
    import android.app.ListActivity;
    import android.os.Bundle;
    import android.widget.ArrayAdapter;
    import android.widget.ListView;
    
    public class MainActivity extends ListActivity {
    
    	private ListView listView;
    	private String[] items = { "Activity1", "Activity2" };
    
    	@Override
    	public void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    
    		listView = (ListView) findViewById(R.id.mylist);
    		listView.setAdapter(new ArrayAdapter<String>(this,
    				android.R.layout.simple_list_item_1, items));
    
    	}
    }

and here it is  activity_main.xml

   

     <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >
    
        <ListView
            android:id="@+id/mylist"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    
    </LinearLayout>

AndroidManifest.xml

        <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.myprojects.schecklist"
        android:versionCode="1"
        android:versionName="1.0" >
    
       <uses-sdk
            android:minSdkVersion="10"
            android:targetSdkVersion="15" />
    
        <application
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <activity
                android:name=".MainActivity"
                android:label="@string/title_activity_main" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
    
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
    
    </manifest>

At least i tried 4-5 methods fix that problem. At last i tried **Project>Clear** and its not fixed too. 
I tried everything and at least i'm working on it about 3days. What's wrong? I'm gonna be crazy.
