Image not Getting displayed on emulator as well as on device

[Rohit Gaikwad]

I am trying to make a splash screen which will be displayed for 5 sec then another activity will start. i am unable to set background and also use image view to view the image on xml file.
but when i Run the apk on emulator or Android device its not displaying the image
the HomeScreen code is

public class HomeActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_home);
		try {
			Thread.sleep(5000);
			Intent cityintent = new Intent(this,CityScreen.class);
			startActivity(cityintent);
			
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

activity_home.xml is

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.rohitrg.bluelagon.HomeActivity" > <ImageView android:id="@+id/imageView1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentLeft="true" android:src="@drawable/welcombls" /> </RelativeLayout>

AndroidManifest.xml is

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.rohitrg.bluelagon" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="14" android:targetSdkVersion="21" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.rohitrg.bluelagon.HomeActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.rohitrg.bluelagon.CityScreen" android:label="@string/app_name" > </activity> </application> </manifest>
