App Crashes (starts for a fraction of second) after installing 'react-native-tor' even if I don't import anything from it.

[cypher-nullbyte]

I installed react-native-tor and then tried to use it.

When i run, npx react-native run-android. It ran then the app crashed right after loading on adb emulator.

Then I even removed the 'react-native-tor' and it ran without any issue.
Once I installed this library again, it crahsed again ( I even didn't use this library anywhere).

I think this issue is similar : #30

May anyone look into it and figure out whats going on.

Hi there, a bit more context is needed please.
Which version or branch are you running ? And can you provide adb logcat 's output just before the crash.

At around 9:31:15 i ran npx react-native run-android. At 31:21 around it ran in android and crashed instantly.
I'll be ready to provide any info to tackle this deadlock.
I didn't even import anything from 'react-native-tor'. Please, look into it. I learned react native only after seeing this library. I'm also trying.

I tried running all options, for 5 hours. I tried for 'main', 'feat-hs', locally. Also installing using npm. I've seen the code.

1. I first tried running the example from react-native-tor-feat-hs and imported this branch locally. But it had issues with gradle version and all.
2. Then I created my own app, putting App.jsx from /example/scr. Didn't work.
3. I also tried other possiblity(ies). I just created a simple rn-app and installed 'react-native-tor' from npm. It crashed here also.
   After running npm remove react-native-tor it continued to work.

From your error log :

07-04 09:31:23.679 5103 5152 E AndroidRuntime: java.lang.UnsatisfiedLinkError: dlopen failed: library "/data/app/~~r7kRfI7f7dCPJwJdV1y2Sw==/com.shoppinglist-saGSfeES9jhZD-29uDgrGA==/lib/x86/libsifir_android.so" not found

Just to confirm ? Did you complete this step from the README

    Link libs

    Android: open android/app/build.gradle and add

    implementation files("../../node_modules/react-native-tor/android/libs/sifir_android.aar")

[cypher-nullbyte]

I tried it too, I put the above line in /android/app/build.gradle inside dependencies:{...}.
But I got this error:

Then I changed minSdk to 26.

It didn't threw error. but nothing happened.
It build successfully and smoothly. But right after launching it crashed.

I'm builing again and sending you the adb logcat 's output just before the crash in this context.
In previous adb logcat's output i didn't added this implementation file though

Notice : 07-04 18:37:53.954. Same problem :(

[cypher-nullbyte]

I think its all graddle version's wrong-doing.

I now tried one more thing, i took 'example' from 'main-branch' changed gradel version to 6.3 (the one given there was showing errors).

However, as u can see here it had issues with @babel. I'm trying within my capabilities, hope it gets fixed soon.

---

More info: I'm using JDK 14, Andoroid Studio 4.2.1

[cypher-nullbyte]

I am successfull in running the example given in your repo.
I changed the version of gradle to 6.3 in example.
I did npm install in example and root folder. There are lots of dependecy issues, we need to upgrade them (gradle version is the deal-breaker).
package [email protected] could not be installed (its showing platform specific, but it was shown optional).

However there is still no way out when it comes to comes to using it inside node_modules (by installing using npm [even locally])
I mean this fix will only work for the example inside the root project 'reactnativetor'.

[gabidi]

Yeah changing the gradle & JDK version is not the way you want to go with RN as far as I know.
I just pushed a few commits this AM to HS branch in regards to how the .so is loaded. Try pulling the latest commits from feat/hs branch. I think that should resolve your loadlib error.

[cypher-nullbyte]

@gabidi it didn't work😖. MinSdk thing is resolved now (after your push).

I am feeling, it may work if I compile everything on my own [android part].
The only thing that works for me is example wrapped inide the 'react-native-tor' (that too after upgrading gradle to 6.3 exact).

You seem to be a pro in tech, I'm just a toddler.
may you guide me through ( I want to understand everything in this project by heart.)
I'll be talking in context of android.
---In android/libs/sifir_android.aar----

• We've done c/c++ socket programming (implemented socks5 & proxy-server right ?) & got .sofile. We also have class files (of java) in the same folder.
• What is the role of these java class files, are they simply bridging the static objects (inside libsifir_android.so) and the main project, i.e. kotlin package. Do you've source code libsifir_android.so. Or, you've referenced them from somewhere. May I have it plsss.

----We've used the above package (class files). In kotlin Project. Am I aprehending Right.

Did I apprehended the architecture of project properly?

I've not installed NDK, can the problem be due to that.
Thank u in adv.

[gabidi]

The Readme answers most of the questions in regards to the stack , and yes, all parts of it are open source and links are included.
If there's something specific I can help you with do let me know :)

[Few Fixes | Windows Only issue]:

I'm using windows. There's a problem when we eject our project from expo in order to use this native-library.

If someone gets this error:

Task :unimodules-react-native-adapter:compileDebugJavaWithJavac FAILED

The Fix is:
at node_modules/@unimodules/react-native-adapter/scripts/autolinking.gradle , at line 97:

'require("expo-modules-autolinking")(process.argv.slice(1))',
switch the quotes like this:
"require('expo-modules-autolinking')(process.argv.slice(1))",

sounds dumb, but expo is working on it [as of 6-7-21].

@gabidi : I've some urgency for a week. pls keep it open.

[gabidi]

You can't use this package (or any other package that uses native code) in Expo.

[cypher-nullbyte]

Yes thats why I ejected.
Gradle versions are causing trouble.

Initially I had Jdk 14 ( gradle 6.3 works with it).
I could run the example in this repo after tweaking its version to 6.3.
(inside react-native-tor/example/android/gradle/wrapper/gradle-wrapper.properties

leaving the gradle version of main tor project to 6.1.1
(inside react-native-tor/android/gradle/wrapper/gradle-wrapper.properties)

But then I created new react-native-app {nothing with expo and all}.
I tried changing its version to 6.3 (as everything worked fine in the examle with these versions). I got this:

I also tried downloading jdk 16, but alas (we've to use gradle version-7 for that to work). It was also showing some errors while i tried using jdk 16 with gradle 7+ in your example too..

Which jdk version you used (jdk 11?). I don't know the exact cause, (graddle is just build automation thing).
