it doesn't save any audio, I even changed to mic temporary, but still can't find nothing on my sdcard:

public class MainActivity extends AppCompatActivity {

    private CallRecord mCallRecord;

    private boolean recording;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mCallRecord = new CallRecord.Builder(this)
                .setRecordFileName("RecordFileName")
                .setRecordDirName("RecordDirName")
                .setRecordDirPath(Environment.getExternalStorageDirectory().getPath()) // optional & default value
                .setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB) // optional & default value
                .setOutputFormat(MediaRecorder.OutputFormat.AMR_NB) // optional & default value
                .setAudioSource(MediaRecorder.AudioSource.MIC) // optional & default value
                .setShowSeed(true) // optional & default value ->Ex: RecordFileName_incoming.amr || RecordFileName_outgoing.amr
                .build();


        final Button button = findViewById(R.id.start_stop);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (recording) {
                    mCallRecord.stopCallReceiver();
                    button.setText("start");
                } else {
                    mCallRecord.startCallReceiver();
                    button.setText("stop");
                }
                recording = !recording;
            }
        });
    }
}

I added all permissions:

requestPermissions(new String[]{WRITE_EXTERNAL_STORAGE, RECORD_AUDIO, PROCESS_OUTGOING_CALLS, READ_PHONE_STATE}, 21);

import static android.Manifest.permission.*;

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

and still nothing
