import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;

}
 
 
public void onActivityResult(int requestCode, int resultCode,Intent data)

private static File getOutputMediaFile(){
    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES), "CameraDemo");
 
    if (!mediaStorageDir.exists()){
        if (!mediaStorageDir.mkdirs()){
            return null;
        }
    }
 
    String timeStamp = "hhhh";
    return new File(mediaStorageDir.getPath() + File.separator +
                "IMG_"+ timeStamp + ".jpg");
}

Can you do instead:

String fn=mediaStorageDir.getPath() + File.separator + "IMG_"+ timeStamp + ".jpg";
println("Saving image at ",fn);
return new File(fn);

And verify the File field is being returned? Also, did you enable the required permission? Not sure if there is also a permission for the camera… just dbl check.

this is the print : “file:///storage/emulated/0/Pictures/CameraDemo/IMG_20180605_220725.jpg”

I found something that i should replace
file = Uri.fromFile(getOutputMediaFile());
to
Uri file= FileProvider.getUriForFile(this, “com.example.android.fileprovider”, file);

file:// is not allowed anymore … we should send the URI through content:// scheme instead which is the URI scheme for Content Provider.

I replace … and have the error : The name “FileProvider” cannot be recognized.
i add : import android.support.v4.content.FileProvider; and have error : The import android.support.v4 cannot be resolved

and what is the “com.example.android.fileprovider” ??

any idea ?

thanx

Please format your code with 3 backticks, to make it easier to read:

@adaptinnovative ===
I have written the code initially put; i have tested it again (OS6 MM), with some little modifs and it works: i can see the folder “camerademo” inside PICTURES and i can see the photo inside it. It is possible that URIfromFile does not work for OS>6 MM, yet you can try and it s esay to change this part of the code. Dont forget to ask permissions on rutime if you using a phone more than lollypop.
