I am following the installation guide but when I try to run the script onobfuscated-app.apk, I am getting the following error. 

Error: A JNI error has occurred, please check your installation and try again

Screenshot: Screenshot from 2020-02-10 13-43-55

Development Environment: java version "1.8.0_241" Gradle Version: 6.1.1

I have tested it on 3 different machines with the same dev environment. 1: Local ubuntu machine 2: Virtual Santoku machine 3: AWS Server ubuntu machine

This is my first time using simplify, kindly guide me if I am missing something. Thanks

P.S: I cloned it recursively as mentioned in build guide.

CalebFenton commented 4 years ago

It looks like the jar built in one second, which is wrong. The error is saying that some classes are missing.

Did you clone recursively? How big is the jar? Did you try clean and rebuild?

Actually it took 16 minutes to build jar on virtual machine, about 3 minutes to build jar on local/host machine and 39 seconds on AWS server. You are seeing 1 second in screenshot because I re run the command with --stacktrace flag. That's why it took just 1 second.

  1. Yes I cloned recursively.
  2. About 60K
  3. I have tried ./gradlew clean build command and this time build failed.

I am not sure why this build failed this time because I already used fresh ubuntu server on AWS. I mean nothing was installed before. It got build successfully but this time got failed.

CalebFenton commented 4 years ago

That jar is well small. Maybe I broke something. Let me look into it, see if I can reproduce.

@CalebFenton I have changed the branch to v1.2.1 and build it again and that's worked perfectly fine. So its something wrong with new code. :)

CalebFenton commented 4 years ago

Good idea.

I rewrote the all the build scripts to be gradle 6 compliant and changed some stuff for sdbg so it's quite possible it's just a 5 minute fix.

@Eightgreen Would you please send the stacktrace? Why it failed?

./gradlew fatjar --stacktrace

Should be good now. Let me know if you still have an issue.
