Below is my code from the main activity and my android manifest:</p> <pre><code>package android.Database; import android.app.Activity; import android.content.Intent; import android.database.sqlite.SQLiteDatabase; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; public class projectsDatabase extends Activity { /** Called when the activity is first created. */ SQLiteDatabase myDB = null; final static String MY_DB_NAME ="projectsDatabase"; final static String MY_DB_TABLE = "projects"; static final int MENU_PROJECTS = 1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); onCreateDBAndDBTabled(); setContentView(R.layout.main); } private void onCreateDBAndDBTabled(){ myDB = this.openOrCreateDatabase(MY_DB_NAME, MODE_PRIVATE, null); myDB.execSQL("CREATE TABLE IF NOT EXISTS " + MY_DB_TABLE + " ( _id integer primary key_autoincrement,"+ "Name varchar(100),"+ "Comment varchar(128),"+ "BookingDetails varchar(255),"+ "Project-Kind integer(3))" +""); } public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); menu.add(0, MENU_PROJECTS, 0, R.string.menuProjects) .setShortcut('1', 'f') .setIcon(R.drawable.icon); return true; } public boolean onOptionsItemSelected(MenuItem item){ switch (item.getItemId()) { case MENU_PROJECTS: Intent iProjects= new Intent(this, projects.class); startActivity(iProjects); return true; } return false; } } </code></pre> <p> </p> <pre><code> &lt;application android:icon="@drawable/icon" android:label="@string/app_name"&gt; &lt;activity android:name=".projectsDatabase" android:label="@string/app_name"&gt;

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.

SQuiL has stopped working due to an internal error.

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