Found Fatal Exception Crashes from Testing #635

Open Mai-hh opened 4 months ago

Mai-hh commented 4 months ago

Hi! I'm a student researcher currently working on a project in the area of Android app analysis. As a part of the work centered around Intents, I found a bug that resulted in crashes after analyzing logs/execution traces. Below are the relevant activities, traces, and adb commands that triggered the crashes.

These bugs may be hidden in unexposed Receiver, but they are worth investigating into to prevent potential issues down the line and addressing to improve the overall robustness and quality. If anyone can be confirm these to be valid bugs first, I would appreciate it, and I can help provide more information as needed.

com.simplemobiletools.musicplayer.helpers.MyWidgetProvider
