Preservation of different names

[jeanid]

How do we keep the photos from the camera? /DCIM/Camera/ under names received as image_iwhere i - these are consistent natural numbers (image_1, image_2, image_3 etc.).

Here's my code:

int n = 0;
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
final Button buttonCheck = (Button)findViewById(R.id.mainButton);
buttonCheck.setOnClickListener(new View.OnClickListener(){
    public void onClick(View v){
        File imagesFolder = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM + "/Camera/");
        File image = new File(imagesFolder, "image_" + n +".jpg");
        Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        Uri uriSavedImage = Uri.fromFile(image);
        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
        startActivityForResult(cameraIntent, 1112);
        if(image.exists()){
        n++;
        image = new File(imagesFolder, "image_" + n + ".jpg");
        cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        uriSavedImage = Uri.fromFile(image);
        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
        startActivityForResult(cameraIntent, 1112);
      }
    }
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data){
    super.onActivityResult(requestCode, resultCode, data);
    Intent intent = new Intent(MainActivity.this, Result.class);
    startActivity(intent);
    }

Code variable n - counter. The problem is, when the camera moves back to the main, the counter drops and the new image file replaces the old one.

Usually time is used to keep the photo in the name. In fact, it's always unique.

String currentTime = new SimpleDateFormat("yyyy-MM-dd_HHmmss").format(new Date());
 File image = new File(imagesFolder, "image_" + currentTime +".jpg");
