How does one invoke Clojure on Android?

0

TL;DR: I can't invoke Clojure methods in Android; I get an error and I'm not sure why.

I am building an Android app for a school project. I've learned Clojure, and I would like to use it for parts of my application. (I am not aiming to write the entire thing in Clojure—just a few libraries.)

I've been able to compile a Clojure program into a .jar and invoke it from Java running on my laptop, but I haven't been able to call even built-in functions in an Android app! I’m guessing I’m missing a library or something, but I’m pretty at sea here.

I made the following to test it out:

MainActivity.java:

package org.wiersdorf.ashton.clojureinterop;



import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.TextView;



import clojure.java.api.Clojure;

import clojure.lang.IFn;



public class MainActivity extends AppCompatActivity {



    private Button BoomButton;

    private TextView myText;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);



        BoomButton = (Button) findViewById(R.id.my_button);

        myText   = (TextView) findViewById(R.id.my_text);



        BoomButton.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                IFn plus = Clojure.var("clojure.core", "+");

                String foo = plus.invoke(1, 2).toString();

                myText.setText("Text: " + foo);

            }

        });



    }

}

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_height="match_parent"

    tools:context=".MainActivity">



    <TextView

        android:id="@+id/my_text"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="Hello World!"

        app:layout_constraintBottom_toBottomOf="parent"

        app:layout_constraintLeft_toLeftOf="parent"

        app:layout_constraintRight_toRightOf="parent"

        app:layout_constraintTop_toTopOf="parent" />



    <Button

        android:id="@+id/my_button"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_marginStart="8dp"

        android:layout_marginTop="8dp"

        android:layout_marginEnd="8dp"

        android:layout_marginBottom="8dp"

        android:text="Button"

        app:layout_constraintBottom_toBottomOf="parent"

        app:layout_constraintEnd_toEndOf="parent"

        app:layout_constraintStart_toStartOf="parent"

        app:layout_constraintTop_toBottomOf="@+id/my_text" />



</android.support.constraint.ConstraintLayout>

When I click the button that shows up, this is the error I get:

The method canAccess was added in Java 9 (see here).

Judging by that stacktrace, which shows a NoSuchMethodException for canAccess, you're using a Clojure jar that was compiled with Java 9 or above, and your Android system is using an earlier JRE.

If you can either upgrade your JRE on Android, or switch to a compatible version of Clojure, that should fix it.
