Unauthorized Use of "AudioRecorder" Project in Violation of Apache License 2.0

[Jesse205]

I. Overview of Violation

I have identified that 中山市驴行科技有限公司 (website: https://www.lvxingetch.com/) has developed and publicly distributed an Android application named "录音者" (package name: com.lvxingetch.lyz), which appears to be built upon your open-source project (Dimowner/AudioRecorder) without proper license compliance. The application does not attribute the original copyright notice in its interface or code, nor does it include the original project's license file, which potentially violates Section 4 of the Apache License 2.0.

Note

Portions of this report were drafted with the assistance of AI tools, but all evidence has been manually verified for accuracy.

II. Core Technical Evidence (Code-Level Comparison)

Through decompilation of the APK and analysis using Dex Editor, the following facts have been established:

• Complete package path retained: The application contains the original package name com.dimowner.audiorecorder in its entirety.
• Internal class structure fully matches: The following developer-defined classes/interfaces are clearly visible in the decompiled output. These names are not system-generic components but are unique identifiers of the original project:

Original Project Classes/Interfaces	Description
TransparentRecordingActivity	Transparent recording UI, non-generic component
AppRecorder / AppConstants	Main controller class and configuration constants
RecordDataSource / FileRepository	Data layer and repository architecture
PlaybackService / RecordingService	Background recording and playback services
AudioWaveformVisualization	Core waveform visualization class
CreateBookmarkDialog / RenameRecordDialog	Bookmark and rename feature dialogs
DaggerARApplication_ / Hilt_ prefix classes	Uses the exact same dependency injection framework and generated class naming conventions as the original project

III. License Compliance Review (Apache License 2.0)

Compliance Item	Status	Explanation
Retain original copyright notice (Copyright 2019 Dmytro Ponomarenko)	❌ NOT retained	No such notice appears in the app's "About" page or in the code
Include the original project's license copy	❌ NOT included	While the APK contains an Apache license text, it is located at /META-INF/androidx/constraintlayout/constraintlayout-core/LICENSE.txt — which is the license file for Google's constraintlayout library, not the LICENCE file from the root of your project
Disclose any modifications made	❌ NOT disclosed	No modification logs or change statements are provided
