How to set MediaRecorder setOutputFile to null?

I am trying to create an audio recorder app that records audio and should save audio only when users click on the save button. But the problem I am facing is that as soon as recording stops it saves automatically. And if I try to set setOutputFile to null then the app crashes.
Code
mediaRecorder = new MediaRecorder();
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mediaRecorder.setOutputFile(AudioSavePathInDevice);
Does Anybody know how to save that audio recording manually?

Call recording issue in Android

I want to implement call recording in my one app, So I have used below questions for reference:
Android Recording Incoming and Outgoing Calls
How To Record Incoming Call in android programmatically?
I am using below code to record a call
recorder.reset();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
But I have also try to use different audio source and output format but it's not recording properly
its recording one-sided call sometimes, and when changing to voice_call and voice_communication its not recording calls at all
In some thread, I found that in some devices it's not working properly but I found some apps in play store which works quite good

Service to detect when MediaRecorder is called by any application

I have an AudioRecorder app that runs in a service smoothly, but when I try to use any Recorder app (Video/Voice Recorder), it gives the following error
Voice: Unable to start a new recording. Other applications are already recording
Video: Recording failed
a similar issue was raised here
I want to know if there is any possible way to set a service to listen to when a MediaRecorder.start() is being called by ANY app or even when the object is created.
Thanks.

Getting onActivityResult in Audio Intent

I need to record an audio using inbuilt audio recorder in android and upload that file to server. i recorded an audio using audio recorder intent but i could not able to get the onActivity Result. can anyone help me please? I am using Samsung Galaxy S.

When I preform an activity as you have stated, I always do the higher of the two then the latter, if both return successful then I integrate the two into 1 Activity. Attempt this test:
1: Record and save Audio to SD (to ensure that your recording is present) then
2: (Using a second Activity) Attempt to upload that File to your server.
If the test is successful, integrate the 2 activities. I hope this helps as you have not provided any code to be reviewed.
