crash at android

[pyummm]

Notice APP crash at plugin at android platform (galaxy tab s2 (sm-t813) 7.0 ), note s4 n915 6.0.1 pdf has multipages, images inside, html size with base64 images 2534130b

Used interface: pdf.htmlToPDF({ data: this.htmlpdf, documentSize: "A4", landscape: "portrait", type: "base64" }, (pdf:string) => {...

Right same code successfully generate pdf with much bigger size (up to 50 images and more) at ios platform (Air 2, iphone 6)

Also notice, at android pdf generates and open with type "share"

cordova-pdf-generator 1.9.3 "PDFGenerator"

[cesarvr]

Can you try updating to the latest version 1.9.8.

Also in this example, I test printing a huge volume of 4K images against iOS and Android (>22), maybe you can see something useful there.

If still not work just post a snippet of that is crashing, Android version, Cordova Version.

[pyummm]

Hello, many thanks for responce, i installed lates plugin version (cordova-pdf-generator 2.0.0 "PDFGenerator"), android-minSdkVersion = 23, cordova android 6.4.0, device has android 7.0

And notice crashes with html size over 1.5mb inclubing base64 images inside this size. here piece of code. also below links to two html sources, which i pass to generator. One generate pdf, other bigger crashes. That are same, just 2 extra photos inside.

                        let options = {
                            documentSize: 'A4',
                            type: this.pdfType,
                            fileName: 'myFile.pdf'
                        };
                        pdf.fromData(this.htmlpdf, options)
                            .then((pdf:string)=> {

------------------updated I get pdf base64 string, write to file and store it to app container.

I am getting a crash in Android as well, printing pdf.fromData using cordova-pdf-generator 2.0.0 , cordova android 6.4.0, android 7.0. No images, just text. Works fine in iOS

Here's some debug info:

Hi @pyummm

I just added your file as a part of this example, this is just an app that I create to showcase multiple use case , if you look at the example "Load With Internal Asset" it will load your sample page crash.html.

Basically I just load the page you send as a string, then:

  var opts = {
    documentSize: "A4",
    landscape: "portrait",
    type: "share"
  }

  pdf
  .fromData(yourPageAsString, opts)
  .then(function(pdf) {
     progressHide() . }).catch(this.failure) 
  })

I got:

I tested this with API>=21

Cheers.

I thought I should post my code. Works well in iOS but crashes the Android App

@macsupport

I think the way you initialise that class is not correct, here is a guide, just follow the instruction until you get the PDF, then you can try your example there I'm sure it will work.

Cheers.

[pyummm]

I confirm, at android type "share" works, "base64" - works just at "small sizes" html IOS works with all types.

Try change at your demo, share to base64

[macsupport]

Thanks, I have read the example page a number of times but the code in the article is for pdf.fromURL and I am attempting to get a specific id within each page, not the entire page, to convert to a PDF using pdf.fromData. I did try the example initially, in multiple ways, but unfortunately, it crashed on both platforms.

[cesarvr]

@pyummm I have try the crash.html you send me, you can try here:

If still failing, please send me the html so I can debug the plugin against it. Cheers.

[cesarvr]

@macsupport can you try the version 2.0.1, I just added some validations to trigger an error in case you send a non-string, if it continue failing just post the error message you are getting if any.

Cheers.

[macsupport]

I installed 2.0.1. Here's the debug console output. The first part of the output is the data (html) from the specific page div id I am saving in the generated pdf with css included.

[pyummm]

I installed sample, and confirm, it crashes at option crash.html from assets with XHR/URL, both, and "Get BASE64".

Also i notify, at IOS, Ipad air 2 and lots other ios devices, plugin works with huge sizes of html, generate documents with about 100 pages, where probably each page include image. Report same as this one crash example, but much huge.

[pyummm]

Around java sources. I not programming java, but found problems around method: getAsBase64() here twolines where runtime error with reason="memory violation" sig=6 appear.

encodedBase64 = Base64.encodeToString( bytes, Base64.DEFAULT ); cordovaCallback.success(encodedBase64);

I play around and not found solution to return long string with callback, probably android/java will have problem with it.

Probably better to store base64 to file right at plugin.

[cesarvr]

can you please post the API level you are using, Also Cordova version? , also the crash is only happening when you try to get the PDF in base64?

[pyummm]

Yes, just base64 and at java big strings operations. cordova (Cordova CLI) : 8.0.0 Cordova Platforms : android 6.4.0

[cesarvr]

Nice, just need now the Android SDK API Level , you can see that in Android Studio , In the emulator section.

[pyummm]

installed SDK API 22->27, compiles from 23 and up, each from 23 and higher generate same bug, emulators none installed

Some additional info inn the debugger I am seeing when trying to print data (html) on Android.

Any update on this issue?

[f18nfz]

I've got the same issue when trying to use pdf.fromURL with the same error messages, did you find a resolution?
