Hello Developers,
Week 3 openSAP course Developing Mobile Apps with SAP HANA Cloud Platform was quite a short unit. Started with
- Introduction to SAP Fiori client,
- device feature support
- How to access on-premise / cloud based Fiori apps
- Integrate on-premise / cloud mobile platform
- Create your own custom Fiori client
Latest SAP Fiori Client 1.5 supports below device OS:
Android : 4.1+
iOS: 7.0+
Windows: 8.1, 10
Benefit of running SAP Fiori apps in the SAP Fiori client are:
- Improved management of the app resources using the cache manager plugin
- Handling of authentication challenges within a web view via AuthProxy plugin
- Customize app title, screen, splash screen
- Native device functionalities
- Security enhancements
- Provisioning the user certificate through SAP Mobile Secure and SMP
My findings:
- If you want to customize SAP Fiori client, make sure to install SMP3 Mobile SDK.
- Before running node create_fiori_client.js command, make sure you have run npm install and can see node_modules folder under C:\SAP\MobileSDK3\KapselSDK\apps\fiori_client path.
Otherwise you might see error, Error: Cannot find module 'unzip' at Function.Module.resolveFilename
3. An easy way to check if an android device has been detected successfully on the PC (via USB) by typing adb devices. If not, please insall the Google USB driver.
4. Proxying HCP fiori content through HANA Cloud Platform Mobile Services (HCPms) not working at the moment.
5. As per this discussion, there seems to be an issue with the gradle-andorid-aspectj-plugin.
Error message: Could not find property 'javaCompiler' on com.android.build.gradle.interna .api.LibraryVariantImpl_Decorated@xxxxx
Workaround: In Fiori_client project, navigate to C:\SAP\MobileSDK3\KapselSDK\apps\fiori_client\myopensapfioriclient\platforms\android\CordovaLib and look for built.gradle file and change its version to 0.9.12
6. SAP has been rebranding with its product and solutions for quite a long time. If you dont find HCPms on SAP HANA Cloud Platform cockpit, dont be surprise, its now 'mobile services' 
7. Easy way to build and deploy an app to android device
cordova build android
cordova run android (on device connected via USB)
OR cordova emulate android (on android emulator)
8. If you dont have SAP Fiori URL (or work email address), you can try out SAP Fiori using sample Data (in Demo mode). e.g. My Inbox, Travel requests, order products etc.
9. If something goes wrong while accessing an application, go to SETTINGS and clear LOG, clear CACHE and clear ALL APPLICATION SETTINGS
10. Fiori URL is always mentioned in appConfig.js file (under C:\SAP\MobileSDK3\KapselSDK\apps\fiori_client\myopensapfioriclient\www)
11. An easy way to generate keystore file (default password: changeit)
12. For signing Android apk
- copy the myopensap keystore to the C:\SAP\MobileSDK3\KapselSDK\apps\fiori_client\myopensapfioriclient\platforms\android\build\outputs\apk
- open CMD command by navigating to java bin folder.
- copy paste below command
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore C:\SAP\MobileSDK3\KapselSDK\apps\fiori_client\myopensapfioriclient\platforms\android\build\outputs\apk\myopensap.keystore C:\SAP\MobileSDK3\KapselSDK\apps\fiori_client\myopensapfioriclient\platforms\android\build\outputs\apk\android-armv7-debug.apk myopensap
I got below result:
13. In case if you get an error like unable to sign jar: java.util.zip.ZipException , follow the solution mentioned here.
14. Optimize apk using zipalign tool > navigate to android sdk folder C:\Users\KansalJK\AppData\Local\Android\android-sdk\build-tools\23.0.1
run below command
C:\Users\KansalJK\AppData\Local\Android\android-sdk\build-tools\23.0.1>zipalign
-v 4 C:\SAP\MobileSDK3\KapselSDK\apps\fiori_client\myopensapfioriclient\platform
s\android\build\outputs\apk\android-armv7-debug.apk myopensapfioriclient.apk
Response: you will get myopensapfioriclient.apk generated in android path.
