About Predix SDK for Hybrid
The Predix SDK for Hybrid includes Reference App Containers for various platforms, the pm command-line
tool, and several services that help you to extend the container.
A Mobile Reference App Container is a native application that includes the Predix Mobile Client Core
Services framework that enables you to load, display, and run your Predix Mobile applications.
• For Android, you build the Predix Mobile Reference App Container for Android.
• For iOS, you build the Predix Mobile Reference App Container for iOS.
• For MacOS, you build the App Container for MacOS.
The Predix Mobile (pm) command-line tool allows you to manage your Predix Mobile apps and your mobile
back-end processes. The pm CLI commands depend on the Cloud Foundry and UAAC command-line tools,
so make sure they are installed and properly configured prior to installing the pm tool. See Predix Mobile
Command-Line Interface (pm CLI) Commands on page 3.
The SDK for Hybrid provides several services as REST APIs to provide functionality to hybrid or native
Mobile applications. The Client SDK consuming application (Predix Mobile App Container) can interact
with these local services following this general URL structure: http://pmapi//.
The Predix Mobile Reference App Container interprets URL requests and delegates them to the services in
the Predix Mobile Client Core Services framework , which respond with a JSON payload describing the
result of the call. See Predix Mobile Client Core Services Framework on page 14.

Predix Mobile Command-Line Interface (pm CLI) Commands
Predix Mobile command-line interface (pm CLI) is a set of command line utility tools Use the pm CLI to
manage your Predix Mobile apps and Mobile Service processes.
The pm CLI includes a set of commands that are invoked through the pm command-line interface. The pm
CLI commands use the following syntax:
pm [options] [command]
Installing the pm Command-Line Interface
Use the pm CLI to manage Predix mobile users, roles, Predix mobile applications, and their web app
dependencies.
Before You Begin
The pm CLI depends on both the Cloud Foundry (CF) and UAAC command-line tools.
• Install Cloud Foundry's cf CLI.
See https://github.com/cloudfoundry/cli#downloads.
• Install Cloud Foundry's cf-uaac CLI.
See https://github.com/cloudfoundry/cf-uaac and Troubleshooting UAA Service on page 25.
About This Task
Install the pm CLI:
Procedure
• Download the pm .zip file from https://github.com/PredixDev/predix-mobile-cli/releases/latest.
◦ For iOS and MacOS platforms, unpack the pm-v1.x.x-Mac.zip file in your workspace.
◦ On the Windows platform, unpack the pm-v1.x.x-win.zip file in your workspace.
pm api
Use this command to display the current target, set the target, or change the target Predix Mobile Client
API Gateway service.
In a typical application-development workflow, you begin by targeting the Predix Mobile Client API
Gateway service. The Client API Gateway and the UAA Service work together to ensure that all clients
that access the Predix Mobile service possess a valid authentication token.
In this example, the command returns an empty target.
$ pm api
info: API>
© 2020 General Electric Company 3You can pass the URL of your Predix Mobile API Gateway host to the command to set or change the target.
For example:
$ pm api https://015272.grc-apps.svc.ice.ge.com
info: API> https://015272.grc-apps.svc.ice.ge.com
Run each pm command against the targeted Client API Gateway. If you do not set a target, any pm
command fails with an error.

pm publish
Use this command to upload a Predix Mobile web app to your Predix Mobile service instance.
The pm publish command takes a –webapp parameter that specifies the path to a webapp.json
file. This file defines the web application to be published. The publish command grants access
permission to the current authenticated user so you can load the app initially with the user account used
for publishing. See the pm grant command for information on granting access to additional users.
© 2020 General Electric Company 9pm revoke
Use this command to revoke access to a Predix Mobile app for a specified user account.
The pm revoke command requires a single parameter specifying a Predix Mobile app by name or a path
to an app.json file. By default it operates on the current authenticated user. However, it also takes a --
user parameter where you can specify a different user for access revocation.
pm routes
Use this command to list all defined routes that the Predix Command Router is aware of.
These routes are used to route commands to individual command processors, which are microservices
that you deploy using Cloud Foundry cf tools. Any document created from your Predix Mobile web app
with a type equal to command can be routed to a command processor and processed.
A command router is a microservice that is tasked with routing pending command documents to
configured command processors. A command document is a JSON document with a type field value as
command and a status field. The command document format is similar to an HTTP request, with a request
and response section contained in the same document.
The Command Router manages the state of a given command from the time the document arrives on the
server until the router writes the result from an invoked Command Processor to the response section of
the document. The Command Router translates a command document into an equivalent HTTP request
to a Command Processor. The HTTP response from the Command Processor is serialized and placed in the
response section of the originating command document.

Predix Mobile Data Access Services
The Predix Mobile Core Services Framework includes a high-level data access service and a low-level data
access service.
Use the high-level data access service (DB) to start replication, query the status of replication, add and
retrieve attachments from storage, and to close the database. It also supports basic document retrieval
and query by type. The low-level data acess service (CDB) provides the ability to read and write
documents and is directly connected to the actual storage engine. Typically, you use the high-level service
for overall storage engine operations and you use the low-level service for direct CRUD operations to the
storage service.
© 2020 General Electric Company 15DB (Data Access High-level) Service
The DB Data Access high-level service provides local database management services. In addition, it
provides an abstraction layer to simplify data-access interactions such as saving and retrieving
documents.

Predix Mobile Notify Service
Use the Notify service to relay event notifications from the client device to the web app, or to alert the
user at a specific time if the container app is not running.
For example, this service can run a JavaScript function in the current web app when the following
conditions are met:
• A specific database document changes.
• The application is about to go into the background.
© 2020 General Electric Company 17• The device's connectivity state has changed.
• The device is currently replicating data with the server.
• A specific time has been reached.
The Mobile Send Command web app example shows how to send a POST request to the Notify service for
a specific event, DocumentChangedNotification, with a document ID. This event is triggered when
a specific document in the data store changes. In the example, the id of the source document is included
in the URL. In this example, gotChanges defines a JavaScript function that is invoked when the
notification occurs. This function is passed as the POST body.

22 © 2020 General Electric CompanyConfiguration Preferences and Properties
Configuration Preferences and Properties
The Predix Mobile SDK has two types of on-device configuration storage: Preferences and Properties.
Application users can change Preferences on a device, whereas a developer sets Properties at compile-
time.
Preferences
Preferences consist of developer-set defaults, user-changeable current values, and a user interface to
change those values.
For iOS, the Preferences defaults are stored in the Mobile applications root.plist file in Xcode. The
Preferences defaults are used to populate the iOS and the macOS’s standard UserDefaults object. In
iOS, the user can manipulate those values using the standard iOS Settings app.
For macOS, since there is no standard Settings app, the reference app container includes a Preferences
user interface that you can mimic to construct your own UI for these values, and then that UI can update
those values in the UserDefaults object.
For Android, the default values are stored in assets/preference_defaults.properties file in
the application's Android Studio project, and the storage implementation uses the Android
SharedPreferences object, along with a sample UI provided in the reference app container.
By default, the server endpoint and default logging level is stored in Preferences, however again, this can
be changed using the PredixMobileConfiguration class. The defaults are shown in the table
below.
Properties
Because properties are set by the developer at compile-time, they are read-only configuration elements
for users, and are not expected to change.
In the iOS and macOS implementations of the Predix Mobile SDK, Properties are stored in the application
project’s info.plist file.
For Android, properties are expected to be in the resources/config.properties file; although this
filename can be changed by updating the configurationPropertiesFilename property of the
PredixMobileConfiguration class.
By default the pm-app name and version configuration is stored in Properties on the iOS, macOS,
and the Android implementations of the Predix Mobile SDK. However, this can be changed by updating the
appropriate properties in the PredixMobileConfiguration object. The defaults are shown in the
table below.
© 2020 General Electric Company 23Configuration Defaults
This table identifies the default key name properties and location properties in the configuration control
class.
Configuration element Key Name Property Location Property
Predix Mobile app name pmappDocumentNameKey pmappDocumentNameConfig
Location
Predix Mobile app version pmappDocumentVersionKey pmappDocumentVersionCon
figLocation
Server endpoint serverEndpointConfigKey ServerEndpointConfigLoc
ation
Logging level loggingLevelConfigKey loggingLevelConfigLocat
ion
Other values may be stored in Preferences and Properties as needed, depending on the platform
implementation. Refer to the exposed properties of the platform’s configuration control class.
Example Configuration Changes
Change App Document Name Key
To change the key used to extract the Predix Mobile app name from configuration from the default
pmapp_name toPredixMobileAppName:
iOS/MacOS
PredixMobilityConfiguration.pmappDocumentNameKey =
"PredixMobileAppName"
Android/Java
PredixMobileConfiguration.pmappDocumentNameKey =
"PredixMobileAppName";
Change App Name Configuration Location
To change the location used to retrieve the Predix Mobile app name from the default Properties
configuration to the Preferences configuration:
iOS/MacOS
PredixMobilityConfiguration.pmappDocumentNameConfigLocation =
ConfigurationLocation.settings
Android/Java
PredixMobileConfiguration.pmappDocumentNameConfigLocation =
PredixMobileConfiguration.ConfigurationLocation.PREFERENCES;

Troubleshooting UAA Service
The following are general troubleshooting tips and issues you may experience when using Security
services.
• Troubleshooting UAA Command Line Interface (UAAC) Installation Issues
• Troubleshooting Oauth2 Issues
Troubleshooting UAA Command Line Interface (UAAC) Installation Issues
There are a number of ways you can install UAAC. The procedure lists recommended installation steps for
Windows and Linux users.
Windows
1. Install Ruby from http://rubyinstaller.org/downloads.
Use the stable version of Ruby (version 2.1.x).
Note: The 64-bit versions of Ruby are relatively new and not all the packages have been updated to be
compatible with it. To use the 64-bit version you will require compiler knowledge, and you will need to
be prepared to solve dependency issues.
2. Install the Ruby development kit.
Follow the installation steps at https://github.com/oneclick/rubyinstaller/wiki/Development-Kit.
3. Download Gem for UAAC, cf-uaac*.gem, from https://rubygems.org/gems/cf-uaac.
4. Install the cf-uaac*.gem gem.
gem install cf-uaac*.gem
5. Test if the installation was successful.
uaac help
Linux
Installation of UAAC on Linux or Mac is easier if you use the bundler gem to install all the required
dependencies for cf-uaac gem install.
1. Verify that the Ruby version of Ruby is a stable version (version 2.1.x).
ruby --version
2. Download Gem for Bundler, bundler.gem, from https://rubygems.org/gems/bundler.
3. Install the bundler gem.
gem install bundler
4. Generate a Gemfile with the default rubygems.org source.
bundle init
The Gemfile is created in the same location as the bundler gem.
© 2020 General Electric Company 255. Edit the new Gemfile to include the gems you want to include in the bundle.
# A sample Gemfile
source "https://rubygems.org"
# gem "rails"
gem 'nokogiri'
gem 'rack', '~>1.1'
gem 'rspec', :require => 'spec'
gem 'cf-uaac'
6. Install all of the required gems from your specified sources.
bundle install
7. Install the cf-uaac gem.
gem install cf-uaac
8. Test to see if the installation was successful.
uaac help
Troubleshooting Oauth2 Issues
Predix platform services use OAuth2 for authentication. Errors related to OAuth2 include the HTTP 401
Authorization error. To troubleshoot an OAuth2 issue, check the claims in a user or application token.
For example, if you receive an HTTP 401 authorization error, you need to make sure that the token was
issued from the correct UAA (iss claim) with the required scopes (scope).
Caution:
Using online tools to decode tokens comes with several risks. If a token is stolen, it can be used by
anyone to access protected resources without any other credentials. Even after a token expires,
its claims information exposes internal details about Predix applications and systems, which can
be used to help in other attacks.
Use the following tools to decode tokens on your local machine:
• UAAC
Use the following command to decode a token:
uaac token decode
Example:
uaac token decode
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJodHRwczovLzEyMzQxMzQz

Note: no key given to validate token signature
iss: https://1234134312413.my-domain.com/oauth/token
scope: test
sub: joe@example.com
26 © 2020 General Electric CompanyNote:
As indicated in the UAAC output message, you can provide a public key to validate the issuer of the
token.
• Base64
The JWT claims are Base64-encoded JSON. If you do not need to validate the JWT issuer, use a tool
that can decode the token claims section.
A JWT token uses the following format:
base64encoded_header.base64encoded_claims.signature
Use the following command to list the claims:
echo | cut -f 2 -d . | base64 --decode
Example:
~/dev$
echo
'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJodHRwczovLzEyMzQxM

SSLException while targeting a UAA instance using UAAC
When targeting multiple UAA instances using UAAC, the client is able to authenticate some UAA
instances successfully, but for others it generates an SSLException.
Cause
One probable cause of this issue is your proxy settings. Additionally the versions of UAAC, Ruby, and
OpenSSL that you are using do not support a new GE certificate and you need to be able to accept TLS1.2
connections.
Solution
As a workaround, you can use the --skip-ssl-validation flag.
Use the following command to check the SSL certificate:
openssl ciphers -v | awk '{print $2}' | sort | uniq
Use the latest versions of UAAC, Ruby and OpenSSL.
© 2020 General Electric Company 27UAA User Account not Found
System cannot find account while setting up user access to your app.
Condition
When adding a user to authenticate as part of granting rights to use your app using the pm grant
command, you receive a message that user account is not found.
Cause
The username is not valid.
Solution
When you grant access using the pm grant command, the user name entered must match the user
account set up in a corresponding UAA instance.
For more information on creating a user in UAA, see Creating Users in a UAA Instance.
User Token Invalid - Expired
When adding a user to use a Predix Mobile app, you receive a message that the user token has expired.
Condition
When adding a user to authenticate as part of granting rights to use your app, you receive a message that
the user token is expired:
{
"error": "invalid_token",
"error_description": "Invalid access token (expired): ... expired at
Sat Nov 14 15:51:53 UTC 2015"
}
Cause
The user has been added, but the token ID (id.url) for the user has expired.
Solution
Use the following pm-cli command to fetch the correct token for the user (where "admin" is the
example user you are trying to add):
uaac token client get admin -s PredixMobile
The command returns the target and context for the user. The following sample shows a successful
response:
Successfully fetched token via client credentials grant.
Target: https://894c559b-430a-4d10-83e8-b6ded9e46ced.here> .com
Context: admin, from client admin
Authentication Not Valid when Creating User
Condition
When you run the pm-add-developer script to create a developer user on the UAA server and grants
them access to the pm.admin group, you get an authentication error.
Cause
The user has been added, but the token ID (id.url) for the user has expired.
Solution
Try re-logging into the UAA server, using the standard uaac commands, and then execute the user
creation operation again:
$> uaac target --skip-ssl-validation
$> uaac token client get
(enter UAA admin password when prompted)
Running pm CLI in Debug Mode
Use debug mode to troubleshoot pm CLI commands that produce error messages.
Condition
When running a pm command, you receive an error message.
Solution
Run the command in debug mode.
The following example shows the syntax for running the pm auth command in debug mode:
pm auth --debug user password
You should see output similar to the following:
HTTP-Util:
GetResource: request options: {
"method": "GET",
"url": "617421.grc-apps.svc.ice.ge.com/login",
"headers": {
"User-Agent": "pm-cli 1.0",
"Accept": "application/json",
"Content-Type": "application/json"
},
"json": true}
© 2020 General Electric Company 29In the example above, if you were certain that your credentials were OK, you would check to make sure
the URL matches the URL bound to your pm-service.

Developing Apps for Apple Devices
Build an App with Native iOS Components
Use this sample code as a model for creating a native iOS app.
This example shows how to create a native iOS app that is similar to the hybrid issues-tracking Sample
app. It uses a native UI instead of a hybrid one. Native apps can be used to create entire iOS apps, or
components of larger native or hybrid apps that require a particular native look and feed, or for
performance reasons, and so on. This example demonstrates a number of techniques, including creating
database views, calling services from native Swift code, and using properties from the web app document
to determine what native components to load.

PredixDev/MobileExample-iOS-NativeIssuesListApp.
Submitting a Predix Mobile Container to the Apple App Store
Use the Apple Enterprise license program to publish apps for general consumption.
About This Task
Many companies that develop mobile software use internal IT groups and procedures to publish apps in
the Apple App Store.
If your app’s audience is exclusively composed of company employees, your company may qualify for the
Apple Enterprise license program. This program allows you to internally publish apps without going
through the App Store and making your app available to the general public. Because an app distributed
through the Enterprise license program does not get published to the App Store, the app is not subject to
the strict review requirements that public App Store apps must pass. See the Apple developer site for
more details: https://developer.apple.com/programs/enterprise/.
If your app is intended for a larger audience than company employees, then it must be published in the
App Store for distribution.
Software development for devices must meet specific Apple iOS requirements. The App Store Distribution
Tutorial is a key starting point in the Apple content repository.
Follow these general steps to register your app in the App Store:
Procedure
1. Register as an Apple Developer: https://developer.apple.com/programs/.
2. Create your app’s bundle ID, App Store distribution certificate, and provisioning profile on the Apple
Developer site.
3. Build and sign your app in XCode.
4. Create the app entry in iTunesConnect, including your screenshots, description, keywords, support
URL, and any other required information.
5. Upload your app binary files to iTunesConnect.
© 2020 General Electric Company 31Apple reviews your app, generally within two weeks. New apps are automatically published after
approval.
If Apple rejects your app, the rejection email includes details. You can then address the problem and
resubmit.
