4. Pilih gambar dan masukan pada folder xxhdpi.
   
5. Isikan coding berikut pada Activity Main pada src.
   

package com.example.canvas2;


import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.view.Menu;
import android.view.View;


public class MainActivity extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

}

static public class canvas7 extends View{
Bitmap gambarkudangambarmu;

public canvas7(Context context){
super(context);
gambarkudangambarmu = BitmapFactory.decodeResource(context.getResources(),R.drawable.aaa);
}
@SuppressLint("DrawAllocation")
protected void onDraw(Canvas canvas){
Paint paint=new Paint();
canvas.drawBitmap(gambarkudangambarmu, 100, 200,paint);
}
}




@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

}

6. Pada coding R.drawable.aaa,”aaa” diganti dengan nama gambar yang anda masukan tadi pada folder xx-hdpi.

16. Ubah AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="in.wptrafficanalyzer.navigationtabdemo"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="15" />

    <application

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@android:style/Theme.Black" >

        <activity

            android:name=".MainActivity"

            android:label="@string/title_activity_main" >

            <intent-filter>
