We are writing sample android application that uses the ngrok-java sdk.
We wrote this build.gradle.kts:

plugins {
    alias(libs.plugins.android.application)
    alias(libs.plugins.kotlin.android)
}

android {
    namespace = "org.example.aoc"
    compileSdk = 34

    defaultConfig {
        applicationId = "org.example.aoc"
        minSdk = 24
        targetSdk = 34
        versionCode = 1
        versionName = "1.0"
    }
    packaging {
        resources {
            excludes += "/META-INF/{AL2.0,LGPL2.1}"
        }
    }
    buildTypes {
        getByName("release") {
            isMinifyEnabled = false
        }
    }
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_11
        targetCompatibility = JavaVersion.VERSION_11
    }
    buildFeatures {
        compose = true
    }
    


}
val ngrokVersion = "1.1.0"
dependencies {
        implementation("com.ngrok:ngrok-java:${ngrokVersion}")
        implementation("com.ngrok:ngrok-java-native:$ngrokVersion:linux-android-aarch_64")
}

When we run the application, it crashes with the following stacktrace:

We also tried an other workaround to load the .so binary manually by extracting it from the ngrok-java-native-1.1.0-linux-android-aarch_64.jar file and put it inside the following directory:
src/main/jniLibs/arm64-v8a
And we load the library from our code using the following code (Right before using the ngrok-java sdk methods):

System.loadLibrary("ngrok_java")

After this, when we run the application we get the following error:

java.lang.UnsatisfiedLinkError: Bad JNI version returned from JNI_OnLoad in "/data/app/~~ymvCDlJkZUFYRKr4zK8sVA==/org.example.aoc-Zw4AZ3HIsPDyBRjKbwPvFQ==/base.apk!/lib/arm64-v8a/libngrok_java.so": 65544

Would you provide a sample android application?

@nikolay-ngrok can you help here?

Nikolay's out for a bit, but I'll take a look in the meantime!

I haven't done any android development before though. Is this something that I should be able to trigger by building/running a sample project in termux, or do I need to get a more complete android development environment and sample app set up?

@jrobsonchase

Oh cool, it was actually easier than I expected to get a "Hello, Android!" project building and running, and I managed to get the same UnsatisfiedLinkError you were seeing. I'll keep digging!

@jrobsonchase

Very confused. Is the android classloader filtering things from the jar?

The attempt to load the native library fails because the call to Runtime.class.getResourceAsStream("/libngrok_java.so") returns null, even though the call to NativeSession.class.getResourceAsStream("/native.properties") is just fine.

They're both at the root of the jar:

$ jar tf Downloads/ngrok-java-native-1.1.0-linux-android-aarch_64.jar | grep -E '(native.properties|libngrok_java.so)'
native.properties
libngrok_java.so

Yet:

var r1 = NativeSession::class.java.getResource("/native.properties");
var r2 = NativeSession::class.java.getResource("/libngrok_java.so");

Finally figured out how to get the .so to actually get included in the apk and am now at that "Bad JNI version returned from JNI_OnLoad" error. I believe the problem is that we don't even define that function, which isn't usually a problem, but maybe Android is just weird?

Edit: ugh, it's from the jaffi helper library which doesn't make it configurable. Oh well, we already depend on a fork of it, so what's one more change? 🙃

Since there are two separate issues at play here, I'm turning this one into the OnLoad problem and #50 into the null getResourceAsStream problem. Pretty sure they're entirely independent of one another.

Hi @jrobsonchase

thank you for having a look at this.
I concur there are two separate issues; that's why we opened this one about the OnLoad problem.

I guess the issues stem from the fact you're using Rust for native code, hence you don't have first-class integration with the Android NDK (at least not yet).

For example, an issue that can be seen in your .so file is that it's missing the SONAME, which is required in Android binaries (https://android-developers.googleblog.com/2016/06/android-changes-for-ndk-developers.html):

$ $ANDROID_HOME/ndk/22.0.7026061/toolchains/llvm/prebuilt/linux-x86_64/aarch64-linux-android/bin/readelf --dynamic libngrok_java.so

This issue is technically fixed in main. If you grab the .so from this release and copy it to your jni libs directory, it should now load cleanly.

That's not to say that it actually works on android yet 😭 I'm going to open a top-level issue for general android support and some more focused issues as I run across them.

Thanks for your patience and the pointers!

With the new .so lib, I also get the same error java.lang.UnsatisfiedLinkError: Bad JNI version returned from JNI_OnLoad again.

If you have any example android project that is working for you, I would appreciate it if you can share it with me.
And also, in which device configuration did you test it?
