body: <p>I'm trying to write something into DB using this code:(got from <a href="https://stackoverflow.com/questions/3037767/create-sqlite-database-in-android">here</a> and edited a little)</p>
  
  <pre><code> package com.example.db;
      import android.app.Activity;
      import android.database.Cursor;
      import android.database.sqlite.SQLiteDatabase;
      import android.os.Bundle;
      import android.util.Log;
      import android.view.View;
      import android.widget.EditText;
      import android.widget.TextView;
      public class MainActivity extends Activity {
       String entered;
  
       public void onClick (View v){
           EditText et = (EditText)findViewById(R.id.et);
            entered = et.getText().toString(); 
       }
       @Override
       public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       EditText et = (EditText)findViewById(R.id.et);
        entered = et.getText().toString();
        SQLiteDatabase myDB= null;
        String TableName = "myTable";
  
        String Data="";
  
  
        try {
         myDB = this.openOrCreateDatabase("DatabaseName", MODE_PRIVATE, null);
  
  
         myDB.execSQL("CREATE TABLE IF NOT EXISTS "
           + TableName
           + " (Field1 STRING, Field2 INT(3));");
  
  
         myDB.execSQL("INSERT INTO "
           + TableName
           + " (Field1, Field2)"
           + " VALUES ("+entered+", 22);");
  
  
         Cursor c = myDB.rawQuery("SELECT * FROM " + TableName , null);
  
         int Column1 = c.getColumnIndex("Field1");
         int Column2 = c.getColumnIndex("Field2");
  
  
         c.moveToFirst();
         if (c != null) {
  
          do {
           String Name = c.getString(Column1);
           int Age = c.getInt(Column2);
           Data =Data +Name+"/"+Age+"\n";
          }while(c.moveToNext());
         }
         TextView tv = (TextView)findViewById(R.id.tv);
         tv.setText(Data);
  
        }
        catch(Exception e) {
         Log.e("Error", "Error", e);
        } finally {
         if (myDB != null)
          myDB.close();
        }
       }
