        File photo = new File(Environment.getExternalStorageDirectory(), "picture.jpg");
        imageUri = FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID + ".provider", photo);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
        startActivityForResult(intent, PHOTO_REQUEST);
}

if (Build.VERSION.SDK_INT > 24){
    imageUri = FileProvider.getUriForFile(BA.applicationContext, BA.applicationContext.getPackageName() + ".provider", photo);
}
else{
    imageUri = Uri.fromFile(photo);
}

AddApplicationText(<provider
   android:name="android.support.v4.content.FileProvider"
   android:authorities="$PACKAGE$.provider"
   android:exported="false"
   android:grantUriPermissions="true">
   <meta-data
      android:name="android.support.FILE_PROVIDER_PATHS"
      android:resource="@xml/provider_paths"/>
  </provider>
)
CreateResource(xml, provider_paths.xml,
   <external-path name="external_files" path="." />
)

This is a wrap for this github project.

It is basically the same as the one posted by @Johan Schoeman plus facerecognition and Barcodescanner (as of now it is configigured to scan all know formats.)

You need to use FileProvider. file-Uris are not allowed anymore.

Please create a new thread in the questionsforum.

Posting to existing threads is a mistake.
