Goal: Android App to show/sort/find csv database content in a table view.

Why does every release has differnt Android APKs (called "flavors"): minSdkXX

• minSdk29 is optimized for Android-10 ("Q") and later: it does not run on Android-9 and earlier.
• minSdk24 is optimized for Android-7 ("Nougat") and later: it does not run on Android-6 and earlier.
• minSdk23 is optimized for Android-6 ("Marshmallow") and later: it does not run on Android-5 and earlier.
• minSdk21 is optimized for Android-5 ("Lollipop") and later; Contains a known vulnerability : it does not run on Android-4.4 and earlier.

How to use CsvViewer?

• Inside a filemanager, click on a file that ends with ".csv".
  • In the "Open with" popup select "CsvViewer".
• If CsvViewer is startet without a ".csv" file it shows some demo data.
• Click a header to sort the table. (^ means sort from small to big; v sort from big to small)
• Long click into table cell will open a context menu to filter the table by column.
• Clicking on the search button "🔍" activates the "row contains search"
  • Example "🔍 2001 SuSI" will show all rows that contain (case insentive) in any column "2001" and "susi".

Features

• Automatic csv format detection,
  • Supported delimiters: ;,:| or
  • Supported optional Quoting: "'
  • First csv row is used as header
• automatic column type detection.
  • Date/Time if format is "yyyy-MM-dd HH:mm:ss" (Example "2026-12-24 17:59:55")
  • Yes/No (aka Boolean) if there are only 2 different values.
  • Numbers (Integer/Long)
  • (not implemented yet): Decimal number (Double)
  • String if no other type is detected.

Requirements

• MinSdk=21=LOLLIPOP (or later)
• enough memory to keep the complete csv file in memory
