Share file uri from ACTION_PICK

Question

im trying to make an app that will ask the user to pick a image file and then send it via intent to another app (Whatsapp in this case but this should work with other apps)

Im doing this to request the file:

 Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    intent.addCategory(Intent.CATEGORY_OPENABLE);

    try {
        startActivityForResult(
                Intent.createChooser(intent, "Select a File to Upload"),
                FILE_SELECT_CODE);
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(this, "Please install a File Manager.", Toast.LENGTH_SHORT).show();
    }

This returns a "content://" URI, but when sending it via intent:

 if (isPackageExisted(whatsAppPackage)) {
        Intent sendIntent = new Intent();
        sendIntent.setAction(Intent.ACTION_SEND);
        sendIntent.putExtra(Intent.EXTRA_TEXT, "Some text");
        sendIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
        sendIntent.setType("image/*");
        sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        sendIntent.setPackage(whatsAppPackage);
        startActivity(sendIntent);
    }else{
        goToGooglePlay(whatsAppPackage);
    }

Whatsapp shows a toast saying the file format its not supported and i can see a stacktrace on the logcat

...

Im not sure if i can share the "picker app" uri with another app, something to do with permissions?

What would be the correct way of doing this? do i need to make a copy of the file so my app would be able to share it?

EDIT:

This is working with other apps like Gmail, but not in whatsapp so is possible to have a solution that works with all or most apps? i dont care if i have to make separate methods for sharing but whatsapp is a must.

The code is working fine on a real device, it's on the android simulator where it doesn't work.

I wasn't expecting it, i had tried in the phone just in case.
