Error while dexing in android version 2.0.11.0

[alekw]

Hello,
I was trying to embedd some torrent client with in android java app.
I am rather C# dev, so sorry if that is obvious mistake or too little details
I failed with libtorrent4j, so I moved here. With stable version as in frostwire for android, app builds ok.
When build with latest beta version 2.0.11.0, I am getting:

`

Task :app:desugarDebugFileDependencies FAILED
Execution failed for task ':app:desugarDebugFileDependencies'.
A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
Error while dexing.
`

I am using (min/compile/target) sdkversion 28, but with different versions I did not see any changes.

Just reporting the bug, I can stay on stable version for my work.

BTW what is the difference between libtorrent4j and jlibtorrent nowadays? Which one should I use for new development?

Best regards

hmm, that's a really vague error, please try sharing more of the output

[gubatron]

are you including all of the .jar files?

you want to include the jar with just the classes, along with the other jars that have the binaries, do not extract them, perhaps you added the .so files straight up?

Hi, thanks for swift reply. Yes, I include total 5 files, exactly like here: https://github.com/frostwire/frostwire/tree/master/android/libs
If I include 1.2.19.0, it is compiling.
If I replace them with 2.0.11.0 and change this line in build.gradle:
def jlibtorrent_version = '1.2.19.0' I got this error.

I dont have my work laptop with me, but this is very easy to reproduce:

• create new project in android studio, I used Basic Activity, but it does not matter
• add 5 jars to libs folder
• add 5 jars to build.gradle as here: https://github.com/frostwire/frostwire/blob/36db686f929089bf185625a357347dfe3ac5dce6/android/build.gradle#L251
• add proguard rule as here: https://github.com/frostwire/frostwire/blob/36db686f929089bf185625a357347dfe3ac5dce6/android/proguard-rules.pro#L78
• Make project.

hmm, wonder if we didn't update the version number somewhere for 2.0.11.0

Are you including the jars here?
https://github.com/frostwire/frostwire-jlibtorrent/releases/tag/release%2F2.0.11.0

[gubatron]

Also, please don't loook at FrostWire's source code right now, FrostWire is still on jlibtorrent 1.2x, we'll be releasing a 2.0 based version in 2025.

[alekw]

Yes, I am including jars from the link you posted.
I believe you will face that issue if you bump version in Frost bite android client, maybe tomorrow I will prepare example.
Problem is in jlibtorrent-2.0.11.0.jar file, when I remove it project builds, but most likely will not work :)

[gubatron]

it's going to be a lot more than changing the jars :)

otherwise we would've released already.

There's a TON of API breaking changes from 1.2.x to 2.0.x

[gubatron]

busy now trying to get android to work with SDK 34+

I'm hoping to merge this today (Android 34+ compatibility)
frostwire/frostwire@master...upgrade-target-sdk-version-34

Once we got that merged and out we'll start the Jlibtorrent 2.0 migration for android and desktop.

Right, but I was just starting development of POC. I had no code yet and could not compile, and it makes sense for me to start with 2.x version to avoid breaking changes. But anyway I just need to download torrent with HTTPS url seed and seed it for few minutes after, so there wont be a lot of work to update it next year to 2.x.

give me a week and ill be testing the api on android

update: done with the android sdk 34+ update, I can now start a new branch to start integrating jlibtorrent 2.0, I'll keep you posted if I come across this DEXING issue and how I solve it. I'll also let you know if I don't have any issues, in which case I'll tell you to look at our Android project files, for now I leave you these to compare against yours:

gradle.properties

# Project-wide Gradle settings.

# IDE (e.g. Android Studio) users:
# Settings specified in this file will override any Gradle settings
# configured through the IDE.

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx10248m
org.gradle.jvmargs=-Xmx2560m -XX:+UseParallelGC

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit

# Nov 23, 2021

DEXing issues are often also caused by proguard-rules.pro

I think we'll also be doing this, if we have issues
