twystd / tweetnacl-android Goto Github PK

I have coped the code from native-lib , the TweetNacl code and the exceptions as well. The gradle syncs well. Now If I try to call the functions in another activity, I get this error

        try {
            KeyPair keyPair = TweetNaCl.cryptoBoxKeyPair();
            byte[] val =keyPair.publicKey;
            LogD(bytesToHex(val));
        } catch (KeyPairException e) {
            e.printStackTrace();
        }

First issue is that to use cryptoBoxKeyPair(), the function in the TweetNacl.java file had to be made static. Now If I run this I get an error that points to this line and throws the exception java.lang.UnsatisfiedLinkError.

    /**
     * Loads the TweetNaCl JNI library.
     * 
     */
    static {
        System.loadLibrary("tweetnacl");
    }

If I comment out this line this error comes

java.lang.UnsatisfiedLinkError: No implementation found for int com.example.varun.vesica.encryption.TweetNaCl.jniCryptoBoxKeyPair(byte[]

In Usage section of the ReadMe.md I am following this line Alternatively, copy the libs and src directories to your own project. but not able to do it.
Could someone tell me how to tackle these errors. Thanks

After importing the project into my project and adding it as a Library and getting it to build, I am now getting an UnsatisfiedLinkError: no tweetnacl in java.library.path. I think I brought the jni/ndk stuff in correctly, but for some reason the library is still not loading. Thanks

Hi,
I am using your library in a project where I need to sign stuff and verify signatures. Sometimes it works correctly, but a lot of the time the app crashes because of a heap corruption.

These are the last few messages in the console. Any idea how to solve this?
