Select your project in project tree and go to the Eclipse menu Project » Clean » Clean projects selected below » select your project and click OK.
If you create *.apk package with proguard sometimes you must back up the project, delete project, and create new project if you are unable to create *.apk file.
Check your AndroidManifest.xml if all Activity is correctly inserted. If you add a library project to Main project you have to insert Activity from library to Main project AndroidManifest.xml
Problem with the library.
I deleted library project from project tree and again put the _library project into the main project. This problem was resolved.
1.)Go to Project » Properties » Java Build Path » Libraries and remove (your projects) click OK.
2.)Go to Project » Clean » Clean projects selected below » select your project and click OK.
3.)Add again your LIBRARY project to your MAIN project Project » Properties » Java Build Path » Libraries.
See image below.

[_id] int NULL,
[word] VARCHAR(255) NULL,
[description] VARCHAR(255) NULL
.separator ";"
.import text_file.txt my_table
- Create text_file.txt and paste this text and save it as UTF-8:
1;word1;my first word
2;word2; my second word - Download sqlite3.exe and put to project folder.
- Run BAT file load.bat and read text instruction from console
- If database created you can open and edit this with sqlite database explorer
- Copy database to Asses Android project folder
- If you want using this database in Android application on device, you have to copy this database to folder on device /data/data/com.MyPackage/databases/
