Memory Leak - Large PDF
I am seeing a memory leak when viewing large PDF files in terms of page count. Using an Apollo 17 Flight Plan PDF memory allocation continues to grow as the user scrolls the document and GC does not clear allocations. Inspecting the hprof it appears this is occurring in native code. I inspected the caching mechanism of the library and it appears to work as intended further indicating this is related to native code holding references it shouldn't. I tested this against 2.7.0, 2.8.2, and 3.0.0-beta.4 finding the same result on each version.
Profiler visualization and hprof dump
I created a branch with the mentioned PDF replacing the sample here https://github.com/ToxicBakery/AndroidPdfViewer/tree/feature/memory-leak-large-pdf
Alternately you can get the PDF yourself from the Nasa website here https://www.hq.nasa.gov/alsj/a17/A17_FlightPlan.pdf
I just tested the flight plan, i actually scrolled through both viewers got to about 400mb of memory then removed and my memory recovered to where i started, didnt find any issues with it unless i wasnt looking hard enough..
That's the leak though right? Those images are not being held reference by the cache they are orphaned and seemingly held by the native code or am I missing something? For comparison opening the same document via drive or a web browser on the same devices does not cause 400+ MB of usage so something isn't quite right.
I'm using a lot of memory due to the smaller images as shown in the images so in effect I'm loading the document twice hence the 300mb over the norm. I haven't looked to see what memory is used on a pc as a comparison but the pdf is built from images and not text so it would be large and consume lots of memory.
I open large drawings in pdf they take a while to open but don't believe I get any memory issues but like I said I haven't looked to deep into it.
@ToxicBakery Android uses Garbage Collector, when items are removed from cache it doesn't mean that they will be removed from memory immediately
I found that if you open a large pdf file, opened pages would cost much memory.So I manage opened pages with LruCache, and call closePage() in time, it works fine. You should add closePage() for PdfiumCore by yourself.
Bit late to the party but adding onto what xybean suggested, I found that you can also use a queue system which will automatically truncate opened pages once they've reached a certain amount. This is particularly helpful on devices with low memory.
After several attempts including that of adjusting values within the Constants.java file regarding caching limits with no discernible effects, I did the following:
-
I forked PdfiumAndroid from barteksc and added the closePage() function as suggested by xybean. You can find an example on his github page.
-
From there, forked the AndroidPDFViewer project by barteksc and added a const variable MAX_PAGES to the PdfFile class. I found that 10 pages gave me acceptable results of around 178mbs at peak memory usage, never going further. My document was relatively graphic intensive being lecture slides and notes, but your mileage may vary with different PDFs. Different pages with different content will yield different memory requirements hence, you'll have to play with this.
-
Declare an integer queue: Queue<Integer> OpenedPageQueue within the PdfFile class. Within the constructor, declare the queue as a LinkedList type: this.OpenedPageQueue = new LinkedList<Integer>();
-
Finally, within the openPage() function inside the PdfFile Class, add the queue truncation logic. Mine went something like this:
public boolean openPage(int pageIndex) throws PageRenderingException {
int docPage = documentPage(pageIndex);
if (docPage < 0) {
return false;
}
synchronized (lock) {
if (openedPages.indexOfKey(docPage) < 0) {
try {
pdfiumCore.openPage(pdfDocument, docPage);
openedPages.put(docPage, true);
// Memory management
OpenedPageQueue.add(pageIndex);
if(OpenedPageQueue != null)
{
if(OpenedPageQueue.size() > MAX_PAGES)
{
int oldPage = OpenedPageQueue.poll();
pdfiumCore.closePage(this.pdfDocument, oldPage);
openedPages.delete(oldPage);
}
}
return true;
} catch (Exception e) {
openedPages.put(docPage, false);
throw new PageRenderingException(pageIndex, e);
}
}
return false;
}
}
It feels a bit hacky to me but it gets the job done nevertheless. I haven't had any issues with leaks using this and rendering seems to be okay albeit a bit slow. Hope this helps anyone who's ran into the same issue.
Edit:
Out of curiosity, I tested the Flight plan PDF and I seem to be getting a consistent 50mbs-60mbs peak despite spamming the scroll/page change functions. For anyone who's curious, the hardware I'm using is a Lenovo TBX103F with Android 6.1 and 1GB RAM.
@HaiYoAshCrow Hi, i can't find the function "closePage" on his github page.Can you tell me where? Thank you!
@yuquan23459 See: https://github.com/xybean/PdfiumAndroid/blob/master/src/main/java/com/shockwave/pdfium/PdfiumCore.java
Do a text search for closePage(PdfDocument doc, int pageIndex).
@HaiYoAshCrow Thank you first! I have forked PdfiumAndroid from xybean,but no maven.properties in project.Then AndroidStudio will report error!
@yuquan23459 It's my personal file used for maven repository, so I haven't upload it. You just need to delete the relevant code.
@yuquan23459 I used barteksc's pdfium and referenced the pdfium subproject in my own project alongside the AndroidPdfViewer as modules. I had issues with the maven plugin which was resolved by adding classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5' to the pdfium's build.gradle.
My pdfium's build gradle is as follows with modifications for :

@HaiYoAshCrow Hi，you mean you used barteksc's pdfium as module and add the closePage method in it.Not use xybean's pdfium as module？
@yuquan23459 Yeah, that's what I meant. Sorry I wasn't too clear. You'll need to reference the subproject since the main project is as a whole, the sample and the library project.
@yuquan23459 If you copy the .so file to your own project, you should copy relevant java files without changing their package name.I guess that you have changed the package name of java files.
@HaiYoAshCrow Hi,i have imported the barteksc's pdfium project as module to the AndroidPdfViewer but load failed!The log is: 03-19 10:16:03.279 6939-6939/?

@yuquan23459 Once you've included the project as a module, you'll need to run ndk-build as per instructions within pdfiumAndroid. Navigate to your {PDFIUM MODULE PATH}/src/main/jni and run ndk-build from the command line. Note that you're going to have to have NDK tools setup: https://developer.android.com/ndk/guides/index.html.
@ToxicBakery Android uses Garbage Collector, when items are removed from cache it doesn't mean that they will be removed from memory immediately
Great knowledge of android. But it crashes after few pages. Please try to found the leak into library. Or at least use LRUCache or WeakReference or something else.
@HaiYoAshCrow @xybean It's cool! My pdf is 400MB big, and when scrolling the pages, the memory rocketed up to 200MB and shut down. But after using your tips, it just goes at best up to 80MB in my Galaxy Note 4. Thank you all!
Hi @Yazon2006 @HaiYoAshCrow @xybean , I have followed the above steps.

Do you want to publish an artifact on maven?

Yeah, I guess you can just remove this plugin

Now the project gets build without any error, but PDF doesn't show up. It just shows empty fragment.
I have migrated the AndroidPDFViewer-master to Androidx. And i have removed everything from bintray.gradle in android-pdf-viewer
Thanks
@Yazon2006 , Thanks a lot. The issue is resolved. After following all the steps (including NDK building), the memory consumption has drastically reduced to 200Mb from 900Mb.
