I’ve built a single ContentProvider as a frontend for my 3 table sqlitedb. It’s my first ContentProvider and i can’t find a good tutorial on how to built it.
The schema is actually very simple.
CONTROLS: _id, title, text, last(time)used, phoneNumber
EVENTS: _id, text, phoneNumber, date, type
NUMBERS: _id, title, phoneNumber
There are several kind of errors, as of now my biggest concern are:
1) I have two tabs with listFragments, tab1 loads CONTROLS, tab2 loads EVENTS. Tab1 will load forever (using the LOADER to make it an asynctask), Tab2 will display the empty message in 1 second (work as intended).
2) When i try to insert something in NUMBERS table i get the below logcat (HAD TO EDIT DUE TO CHAR LIMIT) that tells me the columns don’t exist. (I have tested inserting in other tables, but i think the result is the same) The ContentResolver.insert method will give -1 as a result.
3) when i built a query I usually use:
String selection = MyContentProvider.Data.C_ID + "=";
String[] args = {+ String.valueOf(id)};
as the selection and selectionArgs for the query. With this ContentProvider i have to use:
String selection = MyContentProvider.Data.C_ID + "='" + String.valueOf(id) + "'";
as the selection and null as selectionArgs or i get a syntax error.
This comes up when i invoke this method:
public void save(){
name= etContactName.getText().toString();
number= etPhoneNumber.getText().toString();
String empty="";
if(name.equals(null) || number.equals(null) || name.equals(empty) || number.equals(empty)){
Toast.makeText(this, "Enter both name and number", Toast.LENGTH_SHORT).show();
}else{
ContentResolver cr= this.getContentResolver();
ContentValues values= new ContentValues();
values.put(MyContentProvider.Data.N_TITLE, name);
values.put(MyContentProvider.Data.N_NUMBER, number);
cr.insert(MyContentProvider.Data.CONTENT_URI_NUMBERS, values);
NavUtils.navigateUpFromSameTask(this);
}
}
Last but not least, my entire MyContentProvider class, where, i think, lays the error:

Sidenote:
Those 2 frag won’t add menuitem, i think it’s a ActionBarSherlock fault, but if i extend SherlokListFragment i get an error because the onOptionsItemSelected() is final and i cannot override it.
1 You may want to explain better what is the problem, I didn’t understand.
2 I think that instead of:
you want this:
3 Try to uninstall the app then reinstall it and run it again. Also for the
NUMBERStable you have this line in theContentProvider‘s insert method:Are you sure it isn’t:
?
