body: <p>I want to make my code clean &amp; simple, so I want to create DB but I want to call it from another class through the main activity... I tried to do this but it didn't works... So, how should it works ??</p>
  
  <p>Note: I'm kind a newbie in the android development. So, sorry for this type of question...</p>
  
  <p>This is the main activity:</p>
  
  <pre><code>package com.DataStorage.Excercise;
  
  import android.app.Activity;
  import android.content.Context;
  import android.database.sqlite.SQLiteDatabase;
  import android.os.Bundle;
  
  public class DataStorageActivity extends Activity {
  
      private Context context;
      public SQLiteDatabase db_1=null;
  
      /** Called when the activity is first created. */
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
  
         AccessingDB acc= new AccessingDB(context);
         acc.onCreate(db_1);
  
  
      }
  }
  </code></pre>
  
  <p>the other class that have the DB code.. :</p>
  
  <pre><code>package com.DataStorage.Excercise;
  
  import android.content.Context;
  import android.database.sqlite.SQLiteDatabase;
  import android.database.sqlite.SQLiteDatabase.CursorFactory;
  import android.database.sqlite.SQLiteOpenHelper;
  
  public class AccessingDB extends SQLiteOpenHelper {
  
      public AccessingDB(Context context) {
          super(context, "Test_1", null, 1);
          // TODO Auto-generated constructor stub
      }
  
  
      @Override
      public void onCreate(SQLiteDatabase db) {
          // TODO Auto-generated method stub
  
          db.execSQL(CreateTable());
          db.execSQL(Insert_1());
  
      }
  
      @Override
      public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
          // TODO Auto-generated method stub
  
      }
  
      /*
      public String CreateDB_1(){
  
          String s1= "create database Test_1;";
              return s1;
      }
      */
  
      private String CreateTable(){
  
          String s2="create table Customer(id_1 INTEGER,fn TEXT,ln TEXt);";
          return s2;
      }
  
      private String Insert_1(){
  
          String s3="insert into Customer values(1,'aaa','bbb');";
          return s3;
  
      }
  
  }
  </code></pre>
