    <p>I am writing an app for android. I need to read a txt file and write the data in an SQLite file. I have managed to complete all the code, but the part where it should insert the value into the database is not working. I have given the code below:</p> <pre><code>try{ ContentValues values = new ContentValues(); values.put(KEY_NAME, firstNumber); // Contact Name values.put(KEY_PH_NO, strfinal); // Contact Phone // Inserting Row db.insert(TABLE_CONTACTS, null, values); } catch(Exception e) { e.printStackTrace(); } </code></pre> <p>This code is not entering the value into the database and the database remains empty after the operation is completed. What is wrong with this? Thanks. EDIT: Ok, here is the full code:</p> <pre><code>public class DatabaseHandler extends SQLiteOpenHelper { // All Static variables // Database Version private static final int DATABASE_VERSION = 1; // Database Name private static final String DATABASE_NAME = "feedsmanager.sqlite"; // Contacts table name private static final String TABLE_CONTACTS = "table_to_hold_all_values"; // Contacts Table Columns names private static final String KEY_ID = "id"; private static final String KEY_NAME = "name";//ctid private static final String KEY_PH_NO = "phone_number";//feedname,address;feedname;address etc Context ctx; public DatabaseHandler(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); ctx=context; } // Creating Tables @Override public void onCreate(SQLiteDatabase db) { //Log.d("in onCreate","twitch1"); String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_CONTACTS + "(" + KEY_ID + " INTEGER PRIMARY KEY," + KEY_NAME + " TEXT," + KEY_PH_NO + " TEXT);"; //Log.d("below createcontacts","twitch1"); try{ db.execSQL(CREATE_CONTACTS_TABLE); }catch(Exception e){Log.d("create went wrong: "+e,"twitch11");} //Log.d("below db.execsql","twitch1"); populate(db); } void populate(SQLiteDatabase dbs){ String line=""; try{ InputStream is = ctx.getAssets().open("feedtitlesandaddresses.txt"); InputStreamReader iz=new InputStreamReader(is); BufferedReader br = new BufferedReader(iz); //SQLiteDatabase dbs = this.getWritableDatabase(); while((line=br.readLine())!=null) { //Log.d("fcked here6","twitch1"); StringTokenizer stringTokenizer = new StringTokenizer(line, "&lt;"); String firstNumber=""; String strfinal=""; firstNumber = (String) stringTokenizer.nextElement(); **//Calculations to give values to firstNumber and strfinal excluded ContentValues values = new ContentValues(); values.put(KEY_NAME, firstNumber); // Contact Name values.put(KEY_PH_NO, strfinal); // Contact Phone // Inserting Row dbs.insert(TABLE_CONTACTS, null, values);} dbs.close();}catch(Exception e){Log.d("yeah error is"+e,"twitch12");} }} </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
