Simulink android camera deploy to hardware problem (error)

Hi, please help me in this problem,

I want to use my android phone's camera as an output for my App (using App Designer MATLAB).

I found that I can use Simulink Android toolbox to realize this goal.

The problem is everytime I clicked deploy to hardware, it always shows this error

Component:Simulink | Category:Block diagram error

My block diagram is I connected Android Camera with Android Video Display as dummy trial.

I have followed all steps during the installation of the support package and installed all the latest version of Android Studio.

For your information I am using MATLAB R2019a and Simulink version 9.3

Please help, thank you !

Hi Howgen Pratama Kesuma ,

Please note, the Camera block works fine with Android SDK Build Tools 28.0.3. However, if build tool version 29.0.0-rc2 is present then the above issue comes up.

To resolve the issue, you can uninstall build tool 29.0.0-rc2 and install version 28.0.3

[Howgen Pratama Kesuma]

Hi Sruthi,

I have uninstalled the build tool 29.0.0-rc2 and installed version 28.0.3 using Android Studio.

But the error still persist, it seems that whenever I deploy to hardware, the Android Studio automatically update the SDK Build tools.

Do you have a solution for this ?

Here is the error log:

After uninstalling, please run Android Hardware setup again. Then try deploying the model

Thanks a lot Sruthi ! It solved my problem !

How prevent automatic actualization of build tool? I ran Hardware setup and at momento to build the system actualize tool versión

[Sruthi Yenugula]

Hi Carlos,

Build tools, will not be updated automatically. If you have build tools 29.0.0-rc1 or 29.0.0-rc2. Please uninstall those versions of build tools and insatll 28.0.3 . After completing the above step, run Hardware setup again. Let me know if you face any issues

[Glenn Van Steenkiste]

Hi Sruthi,

I have Matlab 2018b with Simulink 9.2 and I am facing the problem.

I have deinstalled the SDK build tool 29.0.0-rc3 and installed 28.0.3 several times, and each time I ran Hardware setup again.

But each time I let simulink compile for android it reinstalls 29.0.0-rc3. The problem also excists with every block I try in simulink, so not only the camera and screen block.

Is there any way to force simulink to compile with 28.0.3?

I have android studio 3.4.
