Creating android app Database with big amount of data

Question

The database of my application need to be filled with a lot of data, so during onCreate(), it\'s not only some create table sql instructions, there is a lot of

It looks like you are passing all your sql statements in one string. That's a problem because execSQL expects "a single statement that is not a query" (see documentation [here][1]). Following is a somewhat-ugly-but-working solution.

I have all my sql statements in a file like this:

INSERT INTO table1 VALUES (1, 2, 3);

INSERT INTO table1 VALUES (4, 5, 6);

INSERT INTO table1 VALUES (7, 8, 9);

Notice the new lines in between text(semicolon followed by 2 new lines) Then, I do this:

String text = new String(buffer, "UTF-8");
for (String command : text.split(";\n\n")) { 
   try { command = command.trim(); 
   //Log.d(TAG, "command: " + command); 
   if (command.length() > 0) 
      db.execSQL(command.trim()); 
}
catch(Exception e) {do whatever you need here}

My data columns contain blobs of text with new lines AND semicolons, so I had to find a different command-separator. Just be sure to get creative with the split str: use something you know doesn't exist in your data.
