Android fill PDF form

Question

I have .pdf file and multiple forms are there. I want to open my .pdf file, fill the forms and save it from Android development.

Is there any API for A

Answer 1

The native PDF support on current Android platforms (including Android P) doesn't expose any controls for filling forms. 3rd-party PDF SDKs such as PSPDFKit fill this gap and allow programmatic PDF form filling:

List formFields = document.getFormProvider().getFormFields();
for (FormField formField : formFields) {
    if (formField.getType() == FormType.TEXT) {
        TextFormElement textFormElement = (TextFormElement) formField.getFormElement();
        textFormElement.setText("Test " + textFormElement.getName());
    } else if (formField.getType() == FormType.CHECKBOX) {
        CheckBoxFormElement checkBoxFormElement = (CheckBoxFormElement)formField.getFormElement();
        checkBoxFormElement.toggleSelection();
    }
}

(If you click on above link there's also a Kotlin PDF form filling example.)

Note that most SDKs on the market focus on PDF AcroForms, and not the XFA specification, which has been deprecated in the PDF 2.0 spec.
