Filename of MIC recording in progress, reported erroneously

Problem description
When a previous termux-microphone-record is active, another call to it -with a different filename argument- will overwrite the filename reported when calling termux-microphone-record -q or termux-microphone-record -i, before the initial recording ends.

Steps to reproduce

$ pwd
/storage/emulated/0/tmp


$ termux-microphone-record -l 100 -f first.mp4
Recording started: /storage/emulated/0/tmp/first.mp4 
Max Duration: 01:40

$ termux-microphone-record -f second.mp4

Recording already in progress!


$ termux-microphone-record -i
{
  "isRecording": true,
  "outputFile": "\/storage\/emulated\/0\/tmp\/second.mp4"
}

$ ls first.mp4 second.mp4
ls: cannot access 'second.mp4': No such file or directory
first.mp4


$ termux-microphone-record -q
Recording finished: /storage/emulated/0/tmp/second.mp4

$ ls first.mp4 second.mp4
ls: cannot access 'second.mp4': No such file or directory
first.mp4

Expected behavior
Should report first.mp4, as is actually written.

Suggested solution

I suggest that you use another, temporary variable in recordHandler#L239-265 to create the file and assign it to file only if you're going to use it (#L250).

Lines in the code involved
(all in /app/src/main/java/com/termux/api/MicRecorderAPI.java)

• MicRecorderService#L58

• getRecordingInfoJSONString#L168:

• recordHandler#L239-265

• quitHandler#L289

Start in app/src/main/java/com/termux/api/MicRecorderAPI.java, reading MicRecorderService, getRecordingInfoJSONString, recordHandler, and quitHandler at the referenced lines. Reproduce the two-recording command sequence, then verify that status and quit output retain the first filename while the recording is active and after it ends.
