How to call zumero_internal_auth_add_user from Android client

Question

Here's my code which handles this use case. I never got the exact error that you saw (error code 100: unknown error). My code was tested against the android-16 version of the zumero libs, running on a Nexus 10.

public class MainActivity extends Activity {

    private File tempDBFullPath;
    private String dbName;
    private String cacheDir;


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

        //Get the full path to the databases directory. 
        File databasesPath = this.getDatabasePath("blah").getParentFile();
        if (!databasesPath.isDirectory()) {
            //These lines make sure that the databases directory is created.
            databasesPath.mkdirs();
        }
        //Append the time to make sure that we create a new,empty database 
        //and a new internal auth db each time we run this Activity.
        this.dbName = "testdb" + new Date().getTime();

        this.tempDBFullPath = new File(databasesPath, dbName);
        this.cacheDir = this.getCacheDir().getAbsolutePath();



        //Can't do network on the main thread.
        AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>() {

            @Override
            protected Void doInBackground(Void... params) {
                com.zumero.sqlite.SQLiteDatabase db = com.zumero.sqlite.SQLiteDatabase.openOrCreateDatabase(MainActivity.this.tempDBFullPath, null);
                String userDB = MainActivity.this.dbName + "_users";
                boolean bExec = false;
                String serverAddress = "https://zinst12345.s.zumero.net";
                String adminPassword = "PASSWORD";

                Log.v("test", "========  creating internal auth   ==========");

                Cursor c = null;
                if (bExec) {
                    //When I run this one, I get "com.zumero.sqlite.SQLiteException: unknown error: Queries cannot be performed using execSQL(), use query() instead."
                    //That behavior matches the gingerbread android database package.
                    db.execSQL("SELECT zumero_internal_auth_create('" + serverAddress +"', '" + userDB + "', zumero_internal_auth_scheme('zumero_users_admin'), 'admin', '" + adminPassword + "', NULL,NULL,'',zumero_named_constant('acl_who_anyone'),'',zumero_named_constant('acl_who_anyone') );)");
                }
                else {
                    //This one works.
                    c = db.rawQuery("SELECT zumero_internal_auth_create(?, ?, zumero_internal_auth_scheme(?), ?, ?, NULL,NULL,'',zumero_named_constant('acl_who_anyone'),'',zumero_named_constant('acl_who_anyone') );", new String[] {serverAddress, userDB, "zumero_users_admin", "admin", adminPassword });
                    //WATCH OUT! rawQuery doesn't actually execute until the call to moveToFirst.
                    c.moveToFirst();
                }
