Hi,

C++ developer using vscode here. I am starting learning java and find it is inconvenient to stick with vscode compared with Intellij for java(Or maybe I didn't use vscode for java in a right way).

Are there any recommendation for quickly pick up Intellij tricks? I have already imported vscode shortcuts to Intellij but still having tough time to get used with the different UI settings... Is there any useful plugins or other stuff that I need to know at the same time?

Thank you in advance!

Hi everyone,

I am interested in ART fuzzing. I noticed google has already had DexFuzz there with on-device(emulator) and host option. My question is:

1. Are there two options exactly same? Or on-device will cover more components?

2. If there is difference, what are they? like coverage, performance?

From my perspective, host fuzzing is much faster. If on-device and host has the same coverage, then maybe we should abandon on-device option?

Also, is there any way to add instrumentation for ART so I can check the coverage for each iteration of fuzzing?

Thank you!

Hi,

Struggling with finding how ART(android runtime) execute the dex file in details. Like how do I know dex file fails at what phases since I am considering doing some differential testing on ART.

Thanks!

When I use vscode opening AOSP(Android Open Source Project), it crashed with exit code 132. Here is the log I get:

It used to work well before. Is it because the AOSP project is too big(A repo consists hundreds of git repos)

vscode version: 1.130.0 Host system: Ubuntu 24.04.1 LTS (using remote server since the project is on another server)

Hi,

Is it possible to debug ART locally with DEX file and native code without start emulator?

Right now I set up an emulator and use gdb remote to connect which is inconvenient. :(

Thank you!

Hi,

I am using gdb to debug my dex file with some native code. However, when I was trying to check some variables, most of them are optimized out and many c++ code are inline functions.

Is there any way to make the code debug friendly and easier to inspect? Shall I rebuild AOSP with some flags like CFLAGS += -fkeep-inline-functions?

Thank you!

Hi,

I am currently investigating JVM/ART with JNI vulnerability and feel bit lost. (newbie in this area...

If I create a code which cause JVM/ART throws exception, how can I debug so I can know which line of code inside JVM/ART catch this error/illegal code?

And for Android Runtime, how do I do that?

I tried to build custom version of JVM and ART to get the details but it is bit time consuming since each modification needs a rebuild. Also tried gdb and lldb but feeling like it is not an efficient way either (sth like gdb --args java -cp . Main and set breakpoint...)

Thank you in advance!

Hi,

C/C++ developer here. My next project will be a large-scale Java project. In my previous C++ project (~400 developers), we relied heavily on automated static and dynamic analysis pipelines.

What are the industry-standard tools frequently used for:
Static Analysis / Linting (for c++, it's Clang-Tidy or Cppcheck)
Dynamic Analysis / Profiling (for c++, it's Valgrind or Sanitizers)

Thanks in advance!
