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

call recorder doesn't saves recording

m new to android, was just trying to record the calls. After hanging up, recording should be saved but it's not there in storage. can somebody help me with it
public void startRecording() throws IOException {
ditchRecord();
File outFile=new File(OUTPUT_FILE);
if(outFile.exists()){
outFile.delete();
}
recorder= new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(OUTPUT_FILE);
recorder.prepare();
recorder.start();
}
private void ditchRecord() {
if(recorder!=null)
recorder.release();
}
Based on the documentation,
Capturing from VOICE_CALL source requires the CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.
Hence, it looks like what you're trying to do is not possible, unless your app is installed as a system app, which will only work on rooted devices.

Autostart recording in MediaStore

I managed to record audio by sending intent with action MediaStore.Audio.Media.RECORD_SOUND_ACTION.
But is there a way to tell MediaStore application to automatically start recording without the need for user to press record button?
I don't see relevant parameters nor MediaStore.Audio.Media nor in MediaStore.
And same question for video...
You can directly use the MediaRecorder object to record. This way you can control when and how to start the voice recording.
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
