[BUG] Downloading a password protected file gives SecurityException.class

[Gaawk]

📝 Describe the Bug

When calling initWithUrl with the url of the pdf file which is password protected, app crashed for Security Exception. Do we have any way to open password protected file without crashing it?

📖 Library Version

• PDF Viewer Version: [e.g., 2.0.0]

// Open pdf with password
private void openPDFWithPassword(File file, String password) throws IOException {
fileDescriptor = ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY);
LoadParams loadParams = null;
if (android.os.ext.SdkExtensions.getExtensionVersion(android.os.Build.VERSION_CODES.S) >= 13) {
loadParams = new LoadParams.Builder()
.setPassword(password)
.build();
pdfRenderer = new PdfRendererPreV(fileDescriptor, loadParams);
}
}

This code works fine for me in android 11+ with sdk 35 (java), Can anyone please use this code and compile for kotlin for this library.

Unfortunately password protected file is not supported at the moment.
@SolomonJesurathinam LoadParams was added in API 35, it would be inconsistent behaviour for older version If I used this.

@afreakyelf I have done this for Android 11+, the PrerenderV supports from Android 11+. It works fine, I don't know about Kotlin, maybe you can check it once and incorporate it in your library.

It works well with kotlin too but API has to be 35.
