    <p>After months of developing I realize that my app (only using android 2.1) crashes when I rotate screen. I don't know how investigate about this error. What should be the cause? Thanks for advices. Can this "warning" cause error? Unexpected resume of com.example.app while already resumed in com.example.app</p> <pre><code>SharedPreferences prefs3 = PreferenceManager.getDefaultSharedPreferences(this); listener = new SharedPreferences.OnSharedPreferenceChangeListener() { public void onSharedPreferenceChanged(SharedPreferences prefs, String listpref) { preferenze();

    3. COIs com.example.app the name of your app? If so it looks like you're doing something in onSharedPreferenceChanged that's causing an infinite loop, which eventually eats up enough memory to cause a stack overflow. Maybe you've got a line inside of onSharedPreferenceChanged that causes onSharedPreferenceChanged to be called again indirectly?

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).
