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.

@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?

Thank you, Sruthi. Probably there was some issues with my smartphone, but I fix it. I've changed device and now it works.

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.

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

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."

Index exceeds array dimensions. Index value 0 exceeds valid range [1-2049] of array f.
Error in 'slexHARAndroidExample/extractFeatures' (line 133)
ofpk = f(olocs);

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

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