You will also want to move these lines </p> <pre><code>Editor edit = preferences.edit(); boolean autoclear = preferences.getBoolean(autoclearKEY, false); </code></pre> <p>into <code>onCreate()</code> after you initialize <code>preferences</code> or you will get another <code>NPE</code> since <code>preferences</code> will be <code>null</code> until you initialize it. So it should be something like</p> <pre><code>public class MainActivity extends Activity { //saved data stuff needed SharedPreferences preferences; //declare them Editor edit; //private data using saved data String autoclearKEY = "us.mattmccoy.meanfind.AUTOCLEAR"; boolean autoclear; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); SharedPreferences preferences; = this.getSharedPreferences("us.mattmccoy.meanfind", Context.MODE_PRIVATE); Editor edit = preferences.edit(); //initialize them boolean autoclear = preferences.getBoolean(autoclearKEY, false); addListenerBoxes(); if(autoclear == true){ acBox.setChecked(true); }else{ acBox.setChecked(false); } </code></pre> <p>If this doesn't solve your problem then please post full logcat</p>

    3. COYou can declare it as a member variable (before `onCreate()` `Editor edit;` But you can't initialize it until after you initialize your `preferences` in `onCreate()`

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).
