media player (and text to speech) output to phone ear speaker instead of loudspeaker

[pierpa]

hello,

i need to improve my program, a sort of to-do-list

since now, my prog does this: plays ringtone to the loudspeaker through media player and the fake green and red buttons are used to redirect the user to other app pages. the user must read.

now, i want the user to answer the fake call, listening at the internal ear speaker from the tts and then he can read/tap the infos

please, help me to instruct the media player to play to the ear speaker.

regards

Here:

Sub Process_Globals
   Dim mp As MediaPlayer
End Sub

Sub Globals

End Sub
Sub Activity_Create(FirstTime As Boolean)
   mp.Initialize
   mp.Load(File.DirAssets, "break.mp3")
End Sub

Sub SetEarPhone(Value As Boolean)
   Dim r As Reflector
   r.Target = r.GetContext
   r.Target = r.RunMethod2("getSystemService", "audio", "java.lang.String")
   Dim mode As Int
   If Value Then mode = 2 Else mode = 0
   r.RunMethod2("setMode", mode, "java.lang.int")
End Sub

Sub Activity_Click
   mp.Play
End Sub

Sub Activity_Resume
   SetEarPhone(True)
End Sub

Sub Activity_Pause(UserClosed As Boolean)
   SetEarPhone(False)
   mp.Pause
End Sub

You should add this line to the manifest editor:

AddPermission(android.permission.MODIFY_AUDIO_SETTINGS)

It is important to return to the normal state when your app quits (as done in the example code).

Cool. I'm assuming there are other modes too? I had some code I found in my little repository here from another thread, but I believe someone had commented it didn't work. If it doesn't work, are their similar modes for this method?

Dim rf As Reflector
rf.Target = mp
rf.Target = rf.GetField("mp")
rf.RunMethod2("setAudioStreamType","4","java.lang.int")

STREAM_VOICE_CALL = 0
STREAM_SYSTEM = 1
STREAM_RING = 2
STREAM_MUSIC = 3
STREAM_ALARM = 4
STREAM_NOTIFICATION = 5
STREAM_DTMF = 8

This mode actually comes from a different class. It is a mode in AudioManager (in call audio mode):
AudioManager | Android Developers

I haven't played with it a lot so I don't know whether there are other "interesting" modes.

problem with samsung s3

hello

the code works perfectly with sony xperia

with samsung s3, a subsequent phone call has messed audio.

i add a test project.

the test app, on xperia works as intended, while on samsung s3 the phone called audio is covered with terrible noise.

i want that the second button feature would work

warning: on samsung s3 the second button test can damage your ear!

please, help

p.s. the attached project hasn't apk inside of it for uploading problems.
the apk is attached apart

p.s. the "187" number used for testing is the free number in italy for operator problems

Note that you should use File - Export as zip when uploading projects.

This discussion might help: android - AudioManager MODE_IN_CALL interferences - Stack Overflow

hello erel.

you are my god.

i will use that silly 5 seconds trick. damn samsung!

i will just check if the p.Model() is i9300/i9305 and will do that only for sgs3.

for anyone else, i post the code that now works, with the 5 seconds delay

next time i will use the export feature

thanks a lot again

my best regards
