ANDROID SQLITE check if table has data

Question

I'd like to check if my table has records. Here's what I've tried:

if( cursor != null ){
        cursor.moveToFirst();
        if (cursor.getInt(0) == 0) {
        Toast.makeText(getBaseContext(), "No records yet!", Toast.LENGTH_SHORT).show();
        }
    }

Logcat says:

  CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0

Any help is appreciated. Thanks.

Try this

cursor.getCount();

it will return if cursor retrieve data count if this give 0 then there is no data

so

if(cursor != null && cursor.getCount()>0){
   cursor.moveToFirst();
   //do your action
   //Fetch your data

}
else {
 Toast.makeText(getBaseContext(), "No records yet!", Toast.LENGTH_SHORT).show();
    return;
}  

Note : even though you check if( cursor != null ) cursor will not return null value after doing any query, so do this to check the data count in cursor after that
