Unsatisfied Link error while using SQLCipher library

Question

I am using the SQLCipher Library for Android to Encrypt/Decrypt the DB file. I am following the exact steps that were discussed in the API to add the library.

But I am getting a Unsatisfied link error when i run the project... Here's the logcat...

Please give me any reference or hint.

Answer 1

you need to add the .so files into the libs/armaebi folder of your eclipse project and rebuild.

What about if you've done that and still get the UnsatisfiedLinkError? – Sericin

Answer 2

java.lang.UnsatisfiedLinkError happens when the SQLCipher library was not initialized before using.

To solve the problem, call SQLiteDatabase.loadLibs(this); before using.

For example:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    SQLiteDatabase.loadLibs(this);

    // Set up the window layout
    setContentView(R.layout.main);

    //instance of database adapter
    db = DBAdapter.getInstance(this);

    //load database
    db.load("password goes here");

Could you share what version of SQLCipher for Android you are using? We have recently released a new version of SQLCipher for Android with many changes. If you are not currently up to date with the latest release you can get it here.

I've experienced this exception using SQLCipher v2.0 RC4. .so files are included in project... – Gnarled

^ turns out it was yet another Eclipse bug causing this, whereby included libraries werent actually included. – Gnarled

@Gnarled After following setfault's advice, I may have run into the same issue with sqlcipher v2.1.1. It can't find "libraryName "stlport_shared" (id=830025040304)". How did you get around this? – Newsworthy

turns out the libraries have to be in folder "prj/libs" (plural) not "prj/lib"...what a horrible dependency. – Newsworthy
