x/mobile: Java to Go bindings crashes with java.lang.UnsatisfiedLinkError

[sureshg]

I have a sample Android app with Java to Go bindings, built using gomobile bind command. When i try to run this code on Nexus 5 (Android 6) it's always crashing with java.lang.UnsatisfiedLinkError.../libgojni.so: has text relocations. I am not sure whether this is the right repo to report x/mobile issues. Reporting it here because i didn't find any option in golang/mobile

SDK Version

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }

Go bind gradle plugin

go version go1.5.1 darwin/amd64

plugins {
    id "org.golang.mobile.bind" version "0.2.2"
}

This is the same as #12890.

I believe you can build with targetSdkVersion=22, but this may have been fixed by 82d11f. Could you try syncing to the latest gomobile and running init and bind again?

[crawshaw]

@sureshg please reopen this issue if this is not fixed by the latest version of gomobile.

[sureshg]

@crawshaw yeah cleaned up the existing gomobile (if that matters) and ran the following commands with new gradle plugin ("org.golang.mobile.bind" version "0.2.3") . Still having the same issue. Did i miss anything?

  $  go get -u golang.org/x/mobile/cmd/gomobile && gomobile init
  $ ./gradlew -b gobuild/build.gradle gobind

@sureshg, update just gomobile is not enough, see #12890 last messages.
