You need to add GPS data in the file name. I get the GPS data from the DataGP class. Its content is:

public class DataGPS extends Activity { private LocationManager locationManager; @Override protected void onCreate(Bundle savedInstanceState) {// 袙 onCreate 袨袩袪袝袛袝袥携袝袦 TextView 袣袨袦袩袨袧袝袧孝蝎 袠 袩袨袥校效袗袝袦 locationManager 效袝袪袝袟 袣袨孝袨袪蝎袡 袠 袘校袛袝袦 袪袗袘袨孝袗孝鞋 super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); } protected void onResume() {// 袙 onResume 袙袝楔袗袝袦 小袥校楔袗孝袝袥携 袧袗 袩袪袨袙袗袡袛袝袪袗 小 袩袨袦袨些鞋挟 袦袝孝袨袛袗 requestLocationUpdates super.onResume(); if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission.

So add to the file name

 DataGPS dataGPS = new DataGPS(); file = new File(directory.getPath() + "/" + "photo_" + timeStamp + dataGPS + ".jpg");

There is a date in the file name, but in the place of latitude and longitude such nonsense is obtained:

 photo_094127_28062016cod.ru.centre_v00.MainActivity$DataGPS@4222a6b8.jpg

What am I doing wrong ?

    When casting an object to a String type, its toString() method is called. The standard implementation of the method looks like this.

     getClass().getName() + '@' + Integer.toHexString(hashCode())

    Those. The string representation of an object consists of its name and a hash code, as seen in your example.

    If the DataGPS class DataGPS written by you, then you can override the toString method to your liking. Or, if the source code of this class is not available to you, when generating the file name, explicitly call get methods of this class.
