can't find data on my phone

[gmcd310]

Dear Steven, thank you for your work!
I want to know where data is stored in the phone，I can't find data on my phone。

I have used an old samsung phone, so I cannot say that this is accurate for all Android smartphones. For me, I have an app called "My Files". In the app, I can view Internal storage > Android > data > com.stevenmhernandez.csilabeler.

For additional information: this is where I save CSI to the local file (https://github.com/StevenMHernandez/Android-CSI-Labelling-App/blob/master/app/src/main/java/com/stevenmhernandez/csi_labelling_app/Services/FileDataCollectorService.java#L22). There may be some updates needed for getExternalFilesDir for new smartphones, but I am unsure.

Thank you very much Mr Steven，I've found it, My mobile phone is Huawei, and my path is /myphone/Android/data/com.steven... too.

I saw in your paper that CSI amplitude can be displayed through mobile app. I want to know how you do it. I hope to get your help.

Good question. That photo shows a very early version of this project, but I personally found that visualizing the CSI amplitude was not as important as being able to annotate data live. I have added a dedicated issue (#6) for your question, however I cannot promise that I will have time to add this functionality soon.
