Android SMS unicode detect

Question

I would like to know how to detect what coding has been used for SENT SMS (in case I read it from "content://sms/sent"). I check all columns and I didn´t find any information about it there. Reason why I am looking for this is to know, how many messages has been sent. I believe when it is sent as: 160 GSM characters = 1 SMS ; 70 Unicode characters = 1 SMS

Columns: _id thread_id address person date date_sent protocol read status type reply_path_present subject body service_center locked error_code seen deletable hidden group_id group_type delivery_date app_id msg_id callback_number reserved pri teleservice_id link_url

Thank you for any help in advance.

I haven't tried it yet, but I assume you must check BOM marker in a text if you want to relate to its encoding. Try to read this answer: http://stackoverflow.com/questions/4520184/how-to-detect-the-character-encoding-of-a-text-file — Cob013, Jun 20 '13 at 20:18

the SmsMessage.calculateLength method does that pretty well !

read the message's body string from the sms content provider
throw that to calculateLength(body, true)
read the results :
- result[0] = 'number of SMS's required'
- result[1] = 'number of code units used'
- result[2] = 'number of code units remaining until the next message'
- result[4] = 'encoding type that should be used for the message'

Cheers !
