    <p>I've been looking around for awhile but no one really seems to have the same problem so maybe its just a simple programming error.</p> <p>From a fresh install on my tablet the program loads, then if you go to the preference menu and select the nPref text box and enter a value the program is fine. But when you restart the program it crashes initially after a value has been entered.</p> <p>A rough outline of my program looks like this:</p> <pre><code> &lt;import statments&gt; public class Galaxy extends Activity{ public void onCreate(Bundle savedInstanceState) { requestWindowFeature(Window.FEATURE_NO_TITLE); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); //request fullscreen super.onCreate(savedInstanceState); setContentView(new Simulation(this)); //set contentview to my class } public boolean onCreateOptionsMenu(Menu menu) { //create ("inflate") the menu MenuInflater inflater = getMenuInflater(); inflater.inflate(R.layout.options_menu, menu); return true; } public boolean onOptionsItemSelected(MenuItem item) { //check if a menu item is pressed switch (item.getItemId()) { case R.id.m_SETTINGS: Toast.makeText(Galaxy_test2Activity.this, "Preference Launched!",Toast.LENGTH_SHORT); Intent i = new Intent(Galaxy_test2Activity.this, Preferences.class); startActivity(i); return true; default: return super.onOptionsItemSelected(item); } } class Simulation extends View { //I declare my program variables here public Simulation(Context context) { super(context); SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context); //get the preferences int storedPreference = preferences.getInt("nPref", 0); //attempt to get a value from the preferences Log.i(TAG, "storedPref nPref = " + storedPreference); //log it to see if it is working //rest of my program //I also have onDraw and onTouchEvent } } } </code></pre> <p>If you need anything thing else I can post it</p> <p>Thanks!</p>

    2. COThanks a bunch! It worked great, just confused why getInt or getFloat wouldn't work.

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).
