Too many Out of Memory exceptions

We received too many out of memory exceptions with PDFView, so we updated our application to use the new PDFLayout class. However, we still receive such exceptions as I have copied below
Code:

Is there any way to fix this problem or this is a weakness of Radaee?

Hi,
can you please give us more details about that issue..
Can you reproduce this out of memory with all the pdfs? Can you please send us one to test it?
What version of the library are you using? Have you tried with the last beta version ?
Can you please give us your Global.java class?

it seems, u are using lots Bitmap object out of PDFView class and PDFLayout class
a bitmap same to View size is needed for 1 PDFView or PDFLayout.
mostly, costs about 1920 * 1080 * 4 bytes.

others: not invoked PDFReader.PDFClose() when close View or reopen a View,
or not invoked PDFLayoutView.PDFClose().

Actually, I can't give you a specific file which has this problem, since we use a crash report system which tells us how many crashes occur in our app and I don't know which crash has occurred with opening of which file. But an interesting point is that this kind of exception mostly occurs in Samsung devices.
I am using SDK 3.4, but I have not tested the beta version of 3.5 since that is under android studio.
I have not modified Global.java at all. That's the same file in SDK 3.4, I just call Global.init() to set my license info.
FYI, this is a second trace of exception I receive from Radaee.

it can upgrade your eclipse project in this way:
copy JNI libs from last beta version in dir "PDFSample/ViewLib/src/main/jniLibs"
copy resources folder from "PDFSample/ViewLib/src/main/res/raw" to your "res" dir, after this u shall has "res/raw"
copy java codes from "PDFSample/ViewLib/src/main/java/com/radaee/pdf"
copy java codes from "PDFSample/ViewLib/src/main/java/com/radaee/view"
copy java codes from "PDFSample/ViewLib/src/main/java/com/radaee/util"
version 3.4 not auto-relase some objects, u shall free allocated memory manually.
for example:
PDFThumbView.thumbClose();
PDFReader,PDFClose();
Document.Close();

while 3.5 beta override "finalize" method, and can auto-release memory allocated by native lib by GC.
