Hi Longhai Li,

From the information you shared, looks like you have not updated the Android Support package with patch.

Use the following workaround, only if you get the error mention Question section.

To resolve the issue for R2018a,

This issue is with new NDK version. Use this work around for now to get started with Android Support Package. Attached the Androidfix_18a.zip file. It contains 5 files. In MATLAB, go to path where you have placed that unzipped folder and then open the androidfix.m file and click on Run button. Now try Hardware Setup again. If copy files, start MATLAB as administrator.

Hi Sruthi Yenugula,

Thanks for this info. I was trying also to setup for device Galaxy S5.I follow the above solution but still encountering the Test connection error. When typing in MATLAB the command:

 [s,r] = codertarget.android.internal.runAdb(sdkPath,[' shell dumpsys window | grep mCurrentFocus'])

MATLAB command window displays:

s =

255

r =

    ''grep' is not recognized as an internal or external command,
     operable program or batch file.
     '

Thanks a lot Ryan, for providing the information. Will investigate and get back.

Androidpatchfor18b_name.zip

@Ryan, @Danyang, @Longhai, @Jorge : Thanks for your patience.

This patch is only for 18b release, don't use for any other release

Use this patch if you get the following error:

Could not detect TestApp on the device screen. The screen may be locked or turned off. Ensure that your device screen is unlocked throughout the verification process.

Attached the Androidpatchfor18b_name.zip file. It contains 4 files. In MATLAB, go to path where you have placed that unzipped folder and then open the pluginfix.m file and click on Run button. Now try Hardware Setup again. If copy files, start MATLAB as administrator. Thanks for your patience. Let us know if you face any issues.

Hi Sruthi Yenugula, I had the same problem described before, in particular the error "No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android *". I've fixed it using Androidfix_18b.zip, but now I've a new issue. During hwsetup I've encountered problem with the connection test. The error is: "Could not find device configuration file created by TestApp.". How can I solve it?

Dear Sruthi Yenugula. I have R2018b version of MATLAB.

When I try to build an app on my device i get the error:

Cannot write to file androidObjectDetection\\src\\main\\res\\layout\\fragment_app.xml.

This is my situation:

ans = 
  AppBuilder with properties:

Hi Alessio Conte,

If you had installed the latest Android Support package, then no need of applying the patch.

The patch should be applied only if you get the following error during hardware setup

"No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android *"

If we didn't get that error and still applied that patch, i suggest you to uninstall and reinstall the Android Support package.

regarding the below error, looks like permission issues. Please build the models in different directory and see if you get the same issue. please let us know if you face any issues

Cannot write to file androidObjectDetection\\src\\main\\res\\layout\\fragment_app.xml.

Hi yubao cao ,

There is some issue with your MATLAB installation, please reinstall the MATLAB and also the Support Package.

Hi yubao cao ,

I have encountered the same problem as you. Have you solved this problem? How can I solve it? I have been bothered for 15 days. If there is a new solution, please tell me, thank you very much. A good man has a safe life.

Hi Sruthi Yenugula

kingly note that i run pluginfix.m file and its output is "Could not copy .p files : No matching files were found." then i tried to verify the configuration of Android Device and got the same error at the step of testing connection like before "Could not detect TestApp on the device screen. The screen may be locked or turned off. Ensure that your device screen is unlocked throughout the verification process."

Hi Sruthi

yes 'EnsembleModel.mat' was created and i have the above mentioned toolboxs but the issue is the same, meanwhile i'm trying to run slexHARAndroidExample on Simulink itself without deploying it on android device to test it and enter the readings manually but i got the below errors

Index exceeds array dimensions. Index value 0 exceeds valid range [1-2049] of array f.

Error in 'slexHARAndroidExample/extractFeatures' (line 133)

ofpk = f(olocs);

Error in 'slexHARAndroidExample/extractFeatures' (line 62)

Error in 'slexHARAndroidExample/extractFeatures' (line 16)

kindly assist

Hi Shruti,

I am getting the error of " Test connection Could not detect TestApp on the device screen. The screen may be locked or turned off. Ensure that your device screen is unlocked throughout the verification process. " I am using MATLAB 2018b. How can I sort it out?

Hi Aditya,

For hardware setup issue, if your still facing the issue then please execute the following commnads in the MATLAB command prompt when the test app is running on your device(during verify configuration step in hardware setup screens)

Replace the username with your system username while executing. First command would be the path of the Android SDK in your system, that is default location. If you had changed the location please use changed location.

sdkPath = 'C:\Users\username\AppData\Local\Android\Sdk'

[s,r] = codertarget.android.internal.runAdb(sdkPath,[' shell dumpsys window | grep mCurrentFocus'])

Provide the output of above command.

Regarding this error Caught "std::exception" Exception message is:

Bundle#74 start failed: Loading C:\Program Files\MATLAB\R2018b\bin\win64\simulink_plugins\slcg_bhm_plugin\libmwslcg_bhm_plugin.dllf

Either re install MATLAB and Simulink and try again or better contact technical support.

Note: You can run Android Simulink Model only after successful completion of hardware setup screens. But error mentioned above doesn't seem to be related to Android Support Package.

Hi Ribhu,

You can go ahead and create models with Android Support Package, you can ignore that test connection failure.

Ribhu Vajpeyi 2019-9-26

Hi Sruthi,

I tried it without the hardware setup as you suggested for couple of Apps. It's working great! Thanks a lot!
