Debug BB10 Headless Apps is really a hard topic for developers.
Before the latest Momentics update, debug is even harder..
By Momentics 2.1.2, developers can follow this instruction to debug your headless apps.
Here I am going to share my experience for debugging headless apps.
I put the logs into notification and show them in Hub!
If you have some problems on debugging headless apps on BlackBerry 10, maybe this trick can help you and save lots of time! :)
GOGOGO, keep developing on BlackBerry 10!
How To Squash ‘Unresponsive’ or ‘Unable To Terminate’ Errors When Debugging your BB10 App on Device
THERE ARE TWO WAYS TO RESOLVE THESE ERRORS
Open Target Navigator
Window - Show View - Target Navigator
Locate Device Process
Go Under Device Ip - Select Process
Send Signal To Application
Go Under Device Ip - Select Process - Right Click - Click Deliver Signal
Terminal Process/App Manually
Select SIGTERM option - Press OK
After you send the SIGTERM (Signal Terminate) your unresponsive app will disappear from the BB10 device. Success! Now, build (CTRL+B), deploy (CTRL+11) and test again.
Developing on BlackBerry 10 is very easy in many phases.
By Native C/C++, HTML5, Adobe AIR, or Android, developers can easily bring their apps to this new platform.
I like to create "Hybrid App" on BlackBerry 10, whichcontains HTML5 and the native Cascades UI Framework.
The reason why I choose using hybrid apps are because by HTML5 I can do some drawing things, and by Cascades framework I can make my apps have uniformed UI and also the awesome native APIs!
Basically hybrid apps are using webview to load html files, but how can we debug the HTML code when them be wrapped into webview?
The answer is very easy! Use the WebInspector!
Check the QML properties of WebView component, checked the "Web Inspector Enabled".
Next, you can simply connect your devices / simulator to the computer, open the browser and type:
For USB connection: 169.254.0.1:1337
For Simulator of Wifi conection: IP + port 1337
The view of connecting to webinspector
Click into it and you can see the console!
See, is that easy?
Come and try to debug in WebInspector now :D
Just use some simple steps can let you check debug messages!
Open the main.cpp in your project. Only need to add two code snippets!
First： Insert this before int main
std::fprintf(stdout, "%s\n", msg);
Second：Inset snippet after Application app(argc, argv);
Here are the whole code snippets
Enjoy all your dubeg messages! ^^
