Please can you tell me if Sqlite database and Text file are limited in records number and/or file size when used

with the Android Emulator (AVD)?
I try to read and display the records from sqllite database and text file. It works fine on the Android Emulator when the database and the file have little records number (about 80 records). I can read and display (Toast.makeText function) the datas.
When I increase the records number (2800 records) the display does not work, nothing happen. After few times, about 2mn, the Emulator come back on the ANDROID screen.
I try another test. I try to copy the 2800 records sqlite database (bundling the database) from the assets folder to /data/data/net.learn2develop.Databases/databases/ folder. Next I try to read the database from the /data/data/net.learn2develop.Databases/databases/ folder and display each record. I check with DDMS. The database is copied. But the Toast.makeText function display nothing. Again after few times, the Emulator come back on the ANDROID screen.
Thank you for your help.
