4.assets: Package that implements getAssets() to distribute a sqlite db via assets folder and to paste it to the /data/data/YourApp/databases folder.  It takes a very short time to handle a 300kb file: about 2 seconds.  It shouldn't take too long when deployed in the Android phone, hopefully ;-)

3. Psalms13: reads from a text file and writes to sqlite db.

3.1 The text file was created with Psalms of the public domain:


A series of delimiters help the process of parsing using charAt(index) and string.substring(startindex, endindex).  In order to remove the tabs that Excel puts when saving: File Replace: tab with nothing.

The resulting file can be placed in the /data/data/package/files folder with adb push CompleteNoTab.txt /data/data/com.p13/files/CompleteNoTab.txt

The package runs for about 2min and at the end the sqlite db is populated with the 150 Psalms:

sqlitedb:   psalmsdb

Notice that the four fields are: ID, Psalm#, PsalmText, and IsTitle.

In order to push the db for distribution:

adb push psalmsdb /data/data/

2. Sample app that writes to a file in data/data/yourAppPackage/files and reads from it.  It compares the two strings and sends the result to the log (that can be invoked with adb logcat > log.txt).  The file in ../files can be read with cat samplefile.txt

Complete package:

1. Sample app that uses a table layout, linear layout and a sqlite database to store names, phones and email.
