Did you check manifest file
android:hardwareAccelerated="false"
it should be true to fix
android:hardwareAccelerated="true"
from androidpdfviewer.
Please attach output from logcat, I will be able to analyze it
from androidpdfviewer.
The pdfView become blank, the logcat is solely:
" A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 20626"
After few second the app crash.
from androidpdfviewer.
I'm getting this sort of crash (and seldom SIGBUS or just UI freeze and SIGABRT) only if I'm trying to display two PDF files simultaneously.
(Unfortunately, I've got pages in separate files and forced to create a ViewPager
populated with PDFView
s)
I've made some locks that force PDFView
s to work in series, but it works not so good.
Some fatal signals:
A/libc: Fatal signal 6 (SIGABRT) at 0x000001f6 (code=0), thread 14050 (*my package name without first letter*)
A/libc: Fatal signal 11 (SIGSEGV) at 0x00000002 (code=1), thread 14285 (*my package name without first letter*)
A/libc: Fatal signal 11 (SIGSEGV), thread 14563 (AsyncTask #1)
A/libc: Fatal signal 11 (SIGSEGV) at 0x00000002 (code=1), thread 14539 (*my package name without first letter*)
A/libc: Fatal signal 11 (SIGSEGV) at 0x00000007 (code=1), thread 25761 (*same*)
Addresses differ and may be 0xffffffff, 0x00000000, and others.

hey @Miha-x64 i am doing the same functionality as you and getting a similar issue
A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0xffffffc0 in tid 4027 (AsyncTask #2)
[ 06-24 17:37:03.683 304: 304 W/ ]
handle_request(10) debug_value = false;
[ 06-24 17:37:03.733 304: 304 W/ ]
wait_for_sigstope = 19
@barteksc any help would be very helpful
Thanks ;)

@Miha-x64 @hashtaag-vinay-sasalatti I know the reason of problem when using few PDFView
s simultaneously, but it will be hard to fix.
AndroidPdfViewer uses PdfiumAndroid library which is custom compilation of Pdfium library for Android. Android Lollipop introduced PdfRenderer
, which also uses Pdfium. If you are running AndroidPdfViewer on Lollipop and higher, its Pdfium library is replaced by built-in version of Pdfium. And there is no way to override system version of Pdfium. Probable solution is to compile Pdfium with different SONAME, but I'am not an expert in native code.
from androidpdfviewer.
@barteksc thanks for the library and the reply ,
i was just wondering and wanted to ask your input's for problem that i am facing here , please oblige ;P
i have 20 single pdfs which are download one by one from server , so i need to show these 20 files as they are downloaded one below the other , so my solution was i used JoanZapata/android-pdfview in a view pager for 20 items , so it did not have any crash but there was too much of rendering time required so i dropped the approach and tried this lib instead in view pager and its crashing so now i am in a mess ;P
just want to ask , if i can supply multiple pdfs to the pdfview so it shows them one below other , or can u help me with what view i need to use from the lib to render only one pdf in a recycler view or list view item :)
if not possible can u lead me to any approach where i can find a solution for this problem because i am unable to find help anywhere from more than a month .
any help will be appreciated @barteksc @JeanChristophePalyart @Miha-x64 @niekvse
Thanks

@barteksc, so, now we've got two problems — Segmentation Violation and SONAME that clashes with the system one?
from androidpdfviewer.
@Miha-x64 If you use Pdfium provided by PdfiumAndroid, few PDFView
s can be used without problems, so there is only issue with SONAME.

@barteksc, I'm getting
A/libc: Fatal signal 11 (SIGSEGV) at 0x00000007 (code=1), thread 16454 (*package*)
in my own SurfaceView with this dirty method:
public synchronized void fromFile(File file) {
try {
FileDescriptor fd = new FileInputStream(file).getFD();
if (!fd.valid()) {
Log.e("PdfView", "FileDescriptor is invalid.");
return;
}
PdfDocument doc = pdfiumCore.newDocument(fd);
Surface sur = getHolder().getSurface();
if (sur == null) {
Log.e("PdfView", "Surface is null");
return;
}
pdfiumCore.openPage(doc, 0);
pdfiumCore.renderPage(doc, sur, 0, 0, 0, getWidth(), getHeight()); // here
} catch (IOException e) {
throw new RuntimeException(e);
}
}
on KitKat.
On not-first app run I see
D/dalvikvm: Shared lib '/data/app-lib/*my-package*-1/libpdfium.so' already loaded in same CL 0x42009318
D/dalvikvm: Shared lib '/data/app-lib/*my-package*-1/libjniPdfium.so' already loaded in same CL 0x42009318
in logs, but on first run I don't, so your libraries are getting loaded.
from androidpdfviewer.
I have got the same crash Fatal signal 11 (SIGSEGV), code 1, fault addr 0xffffffffffffff in tid 1327 (AsyncTask #3)
and i dont know how to fix it
from androidpdfviewer.
@Miha-x64 @hashtaag-vinay-sasalatti Please check version 1.1.2, it fixes using multiple PDFView
s at the same time.
@JeanChristophePalyart @niekvse @macjay Please check version 1.1.2, it should help
from androidpdfviewer.
@barteksc Thanks for that , i will check and update you asap
Thanks ,
Vinay
from androidpdfviewer.
@barteksc I changed to version 1.1.2 and I still have problem with the this particular file. With others pdf files it ok.
(I'm testing on Elephone P60000 Pro Android 5.1, AP22)
from androidpdfviewer.
@JeanChristophePalyart Unfortunately I cannot reproduce this issue on any of my three devices (4.0.3, 4.2.1 and 5.0.1), documents opens without any problem. Could you try opening this file using built-in PdfRenderer
(https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html)? There is also simple example available https://github.com/googlesamples/android-PdfRendererBasic
from androidpdfviewer.
@barteksc Thank you .I have update to 1.1.2,there is no problem in my nexus 5,but still have the problem in 魅蓝note2
from androidpdfviewer.
@macjay So, now we have serious problem. I cannot reproduce and therefore debug this issue. Please check if my previous post (with PdfRenderer
) works for you
from androidpdfviewer.
@barteksc, thank you for your fix.
As it turns out, some sequences of PDFs work great and some are not.
They both have format version 1.6, but ones with the 'Author' field set to 'InDesign CS6 (Windows)' giving crash on Asus Nexus 5 (2012) 'grouper' (API 21). And all of them giving crash on my HTC Evo 3D 'shooteru' (API 19).
from androidpdfviewer.
@Miha-x64 Not good. It looks like pdfium itself may have some strange bugs...
from androidpdfviewer.
@hashtaag-vinay-sasalatti Yay, finally it works for someone ;)
from androidpdfviewer.
yes it worked for me and m one happy guy now , haha ;P
hey @barteksc i have observed one problem now (just want to improve) OnLoadCompleteListener is not giving me a correct callback after load complete (OR) maybe its displaying a white blank screen before the pdf is drawn , now here i need some inputs please
and one more thing is since i have 20 views in view pager and when i scroll back from 3rd to 1st position, again the pdf loads with a blink , how can i change it such that its already there ..
if any updates on my query please hit me back , but btw thats one awesome lib there .
Cheers ,
Vinay
from androidpdfviewer.
@hashtaag-vinay-sasalatti OnLoadCompleteListener is called after PDF file is loaded and ready to render on view, so you see white page for a while.
ViewPager adapter keeps 3 instances of pages - visible page, page to the left and page to the right. When you slide to next page, old left page is destroyed and new page to the right is instantiated. Keeping all 20 PDFView
s in memory would quickly throw OutOfMemoryError exception. Thanks to the adapter behavior, you only keep 3 instances and when you scroll from 3rd to 1st page PDFView
is loading and rendering document.
from androidpdfviewer.
@barteksc Ok thanks
but some times pdf won't load even after waiting for long time , this is my method below it is inside fragment item of view pager
private void showPdf(String filePath) {
File PDF = new File(filePath);
photoView.recycle();
photoView.fromFile(PDF)
.pages(0)
.defaultPage(1)
.showMinimap(false)
.swipeVertical(false)
.enableSwipe(false)
.onDraw(new OnDrawListener() {
@Override
public void onLayerDrawn(Canvas canvas, float pageWidth, float pageHeight, int displayedPage) {
}
})
.onLoad(new OnLoadCompleteListener() {
@Override
public void loadComplete(int nbPages) {
progressBar.setVisibility(View.GONE);
}
})
.onPageChange(new OnPageChangeListener() {
@Override
public void onPageChanged(int page, int pageCount) {
}
})
.load();
}
it won't load pdf sometimes , am i using it wrong ? sorry m troubling u many times :)
from androidpdfviewer.
@barteksc The document attached to my first post works with pdf Renderer. Therefor this one his limited to Lollipop.
To open "pdfSample.pdf" I'm doing
pdfView.fromFile(pdfFile)
.defaultPage(1)
.showMinimap(false)
.enableSwipe(true)
.onLoad(this)
.onPageChange(this)
.onError(new OnErrorListener() {
@Override
public void onError(Throwable t) {
t.printStackTrace();
}
})
.load();
EDIT:
It's working on Android 4.2.2, 4.4.2, 6.0.1
EDIT 2:
Tried also on another mobile with Android 5.1 (Samsumg) and works. Finally only the Elephone crash on this particular file...
from androidpdfviewer.
@barteksc, with new version of the library there is no crash anymore. Thank you! :) 👍
