How to avoid/override the password dialog presented by PDFViewCtrl for Android?

[Anderson Konzen]

Q: When trying to open a protected document using PDFViewCtrl for Android, a dialog is presented so the user can enter the password. How can I avoid this dialog and use my own custom dialog?

A: In order to check if a password dialog should be presented to the user, you can use the following code before setting the doc in PDFViewCtrl:

1. To identify if a dialog should be presented (ie, the document is protected):

PDFDoc doc = new PDFDoc(...);
boolean prompt = false;
SecurityHandler sh = doc.getSecurityHandler();
if (sh != null) {
    if (sh.getPermission(SecurityHandler.e_doc_open)) {
        PDFViewCtrl.setDoc(doc);
    } else {
        prompt = true;
    }
} else {
    prompt = !doc.initSecurityHandler();
    if (!prompt) {
        PDFViewCtrl.setDoc(doc);
    }
}
if (prompt) {
    // Show password dialog
}

2. Once you get the password from the user, you can do the following:

String password = "get_password_from_dialog";
if (doc.initStdSecurityHandler(password) ) {
    // Password correct, open document.
    PDFViewCtrl.setDoc(doc);
} else {
    // Password incorrect
}
