Is it possible to supply prefilled SQLite DB to my app? I want to use db as ordinary SQLite db which will have tables filled manually and I want to include it into my .apk file.
Yes, include it in your assets folder and copy it into the /databases folder when your application first launches.

try this
private void copyDataBase() throws IOException{
//Open your local db as the input stream
InputStream myInput = myContext.getAssets().open(DB_NAME);
// Path to the just created empty db
String outFileName = DB_PATH + DB_NAME;
//Open the empty db as the output stream
OutputStream myOutput = new FileOutputStream(outFileName);
//transfer bytes from the inputfile to the outputfile
byte[] buffer = new byte[1024];
int length;
while ((length = myInput.read(buffer))>0){
myOutput.write(buffer, 0, length);
}
//Close the streams
myOutput.flush();
myOutput.close();
myInput.close();
}
Including in the assets folder is one option (Apk size will be increased.)
How about storing the pre-filled db on any cloud storage service provider and downloading the file on the first run of the app?
