iOS Tutorial Installing B4i-Bridge and debugging first app

Erel · Oct 21, 2014

B4i-Bridge is an application that you install on the device.
It has three purposes:
1. Launch the installation process when needed. This step is done with Apple Configurator 2 if using a local builder (https://www.b4x.com/android/forum/threads/installing-apps-with-apple-configurator-2.128397/).
2. Run the installed app (when installation is not needed).
3. The bridge is also the WYSIWYG visual designer.
4. Starting from iOS 16 you need to enable developer mode under: Settings - Privacy & Security -> Developer Mode

You need to install B4i-Bridge once. It is done from the device browser.

This video tutorial shows the steps required in order to install B4i-Bridge.

The important steps are:
- Set the package name based on the provision app id.
- Build B4i-Bridge: Tools -> Build Server -> Build B4i-Bridge
- Open mobile Safari and navigate to the link displayed in the compilation window.
- Install B4i-Bridge and run it.

Transcript:
1. Create a new project and save it.
2. Set the package name based on the provision app id (Project - Build Configurations).
3. Tools - Build Server - Build B4i-Bridge app.
4. The compilation dialog will show the link that you need to enter in the device browser.
5. Click on the Install button and confirm the installation.
6. Press on the Home key. B4i-Bridge app should be installed.
7. Start B4i-Bridge. A message with the ip address will be displayed.
8. Set this address in the IDE under Tools - Device IP Address.
9. Run the program. Approve the installation on the device and click on the new installed app.

Note that this is a real device. Not an emulator.

Tips:

- B4i-Bridge must be in the foreground for it to be able to start an installation or to run the application. In most cases it will be in the foreground automatically. If it is not in the foreground then you need to click on it to bring it to the foreground.

Troubleshooting:

Device errors:

1. Make sure that the mobile provisioning file includes the device UDID and that the UDID doesn't start with ffffff (this is a fake id).
2. Select 64 bit under Tools - Build Server - Server Settings.

Compilation errors:
1. First follow the steps in this tutorial: http://www.b4x.com/android/forum/threads/creating-a-certificate-and-provisioning-profile.45880/
2. Make sure that the App Id ends with a wildcard.

Thank for suggestion.
Erel, I see that App explicit Id have push flagged but App with asterisk no... Any suggestion how enable this?

Please start a new thread for this question.

Erel I have tried to do what your instructions say multiple times, and I think my old brain is missing something.

I get the following when I try to create the bridge, does any of this ring a bell? Thanks! What it boils down to is a "No identity found" error.

Was this issue resolved?

Yes, when in doubt delete everything and start over again.

Erel · Oct 24, 2014

Maybe the provisioning profile was tied to the wrong certificate.

Alberto Iglesias · Nov 7, 2014

Erel,

you can provide the BRIDGE.IPA in this forum?

So for those who have jailbroken devices make more easy!

Tks.

Alberto

Erel · Nov 7, 2014

Once B4i is released you will be able to build B4i-Bridge and download it as an ipa file.

Alberto Iglesias · Nov 7, 2014

Perfect! thanks Erel

So very excited about b4i! Been trying to make an old macbook work (replacing hard drives and such) so I could try to figure out xCode. So relieved that there is simpler way thru b4i.

EDIT: Found the original post, questions answered here :http://www.b4x.com/android/forum/threads/b4i-beta-to-be-released-next-week.45606/

Thanks Erel, for making mobile app development accessible!

Hi,

I have installed the compilling server on my mac and the various certificates. But when I go to compile/install the b4i bridge it is not compilling (following the video exactly). The last part of the output is:

/Users/sean/UploadedProjects/b4i_default/build/B4iProject.build/Release-iphoneos/B4iProject.build/Objects-normal/armv7/main.o
/Users/sean/UploadedProjects/b4i_default/B4iProject/main.m:11:9: fatal error: 'iDesigner.h' file not found
#import "iDesigner.h"
^
1 error generated.

Error: ** BUILD FAILED **

The following build commands failed:
CompileC build/B4iProject.build/Release-iphoneos/B4iProject.build/Objects-normal/armv7/main.o B4iProject/main.m normal armv7 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)

this I presume is a missing dependency at compile time. I have the latest xcode on the mac which I presume is 6, not sure if it might even be a later version.

Seems like the Libs folder is missing on your Mac computer. There should be a folder named Libs in the folder of B4iBuildServer.jar. All the libraries including iDesigner.h should be there.

Thanks Erel that was the problem. I setup a desktop link to the build server to save typing every time, which did start it ok, but it did not see the libs folder. Got around it by aliasing a script which changes into the correct folder first then runs the server. In Windows and even debian I can make a desktop shortcut and tell it the working folder, OSX has yet to learn this. Just got it all working, another brilliant effort on your part. Thanks, my first app took about 20 seconds to make.

Erel,
I installed the bridge at the device, he starts listening on his IP, I connect device IP on B4I, when I compile my project, it creates an icon on the phone, open the icon, and again starts waiting for the debugger on his IP, run again my project and it complains that Rapid Debugger failed to connect to device.

I reboot the device with no luck

Compile & Debug outputs:
Parsing code. 0.04
Compiling code. 0.41
Compiling debugger engine code. 3.70
Building Xcode project 0.05
Sending data to remote compiler. 2.97
Compilation completed successfully.
Make sure that B4i-Bridge is started (10.8.24.123).
Manually launch the app after installation.

** The bridge is OK, as I can connect with the designer to the device with no problems at all

klaus · Nov 14, 2014

As the message says.
You need to manually launch the program on your device !
Haven't you seen a message, on the device, asking to to install the program ?

fbritop · Nov 14, 2014

I have launched the program on the device, it says the IP address and Waiting for IDE. Althow the IDE IP points to the device, it keeps waiting forever.

Have restarted both, mi machine and the device with no luck

klaus · Nov 14, 2014

Have you started the PROGRAM on the device, clicked on the program icon ?

fbritop · Nov 14, 2014

As I just posted, I have launched the program, it apears a waiting icon with the device IP and a message that says, Wainting for the IDE to connect

Using iOS 7.1.2

klaus · Nov 14, 2014

Can you explain in detail what you have done.
After loading a program:
- I run in the IDE menu Tools / Build Server / Build Basic4i-Bridge App.
- Run the program
- Then you should see the message asking for installation.

fbritop · Nov 14, 2014

OK, Fresh from zero
Build B4I Bridge
Navigate to the URL that the Compile tells me (63.135.170.51:51041/xxx) on the device
Click install APP on the device.

It asks to install my program, install, click to open, the program opens and it says on the screen that is waiting for the IDE to connect, which never happens.

The IDE at the status bar says: Trying to connect to device (10.8.24.123).

The IDE never connects to the IDE for debugging
