I am doing some reverse engineering to get the .dll of a game.
I have tried following the instruction to decrypt the assembly-Csharp.dll using gcore but when I try to open the file and recover it on winhex it says
"9 file headers were found but 0 files were retrieved"
Is there any useful software you guys know?

I have a .mdx file that infact is a dictionary database (some android apps like bluedict can read its data).
I have used Daemon.tools but it could not open it.
I was looking for any library or sources which helps me to read MDX dictionary files in Java, I have found some resources already such as KnIfER/mdict-java but it does not work in Android Studio (it has errors on accumulation_blockId_tree.xxing(new myCpr(position,1)).getKey().value line and it is connot resolve symbol 'value'). Does any one knows a good source about these files and possible libraries which could be used for it?.
Well, actually this is my java project.
the error mentioned is just a problem of jdk version. you can add <> parentheses after myCpr and convert return of xxing to type myCpr<Integer,Integer> .
But now, I have very much reduced usage of rbtree and use more binary list searching.have a look there.
I want to build an ocr app in android.For that i am using tessaract library.I am following this turorial ocr tutoial it says follow below steps
Download the NDK & extract to C:\ drive-Done
Set NDK Path & Android SDK path to PATH variable in Enviorment Variable.-Done
Download tessaract library and extract it to C:-Done
open command line & go inside tessract folder ibn downloaded library.-
Write ndk-build-Not Done
When i write ndk-build it says the system can't find the specified path.
Please tell me how to resolve this issue.I have already spent lot of hard time on this.
Thanks in advance.
If you re-read the link you posted, you may notice this line from the author:
Attention: if you fail at any of the above steps, you are not ready for this shit yet. Better grab an introduction to android development course, read a book, then come back to this tutorial. You’ll just waste time and nerves and you’ll bitch about it in the comments that this crash, this doesn’t work. (PS. no, I will not send you the source code on your email, stop spamming k thx.)
You should seriously consider his advice - working with the Android NDK only gets more difficult from here.
You're probably getting that error message because cmd couldn't find the ndk-build program, which is located inside the root of android-ndk-r10e. Possible causes:
You made an error when editing your PATH variable - make sure each file path is separated by a semicolon and that you provided the full path to your NDK install.
Your PATH is too long - the max length is 260 characters. See this page for more info. tl;dr: prefix \?\ to your PATH to get around this length limit.
You had cmd open when you set the variables - try restarting the cmd
program or even restarting your machine.
I am in the process of migrating my scripts from python SL4A to QPython (can't get SL4A to work on android lollipop).
I can't save a file to the disk
So I am using:
with open("foo.txt" ,"a") as f:
f.write(theInfo)
And I get
IOError: [Errno 30] Read-only file system: 'foo.txt'
I know what the error means, I just don't know where to save the file...
Thanks for the help,
marbs
The error is saying that you are in a protected part of a file system.
That means you may want to save the file in an un-protected part.
So, you may want to replace the "foo.txt" part with "/mnt/sdcard/foo.txt" or "/storage/sdcard0/foo.txt" or whatever is the path of internal storage on your phone.
Do you understand what am I saying?
Qpython has disabled writing to files, my recommendation is to find a different script interpreter like the inpython app on android, or the python module in Termux and run it from there.
I have .docx file in assets folder and use this part of code to to read it
AssetManager am = context.getAssets();
InputStream is;
is = (InputStream) am.open("amaretti.docx");
XWPFDocument hdoc=new XWPFDocument(OPCPackage.open(is));
and jars for this are:
poi.jar
poi-ooxml.jar
But shows me an error:
08-27 18:16:31.660: I/dalvikvm(23221): Could not find method org.openxmlformats.schemas.wordprocessingml.x2006.main.CTDocument1$Factory.newInstance, referenced from method org.apache.poi.xwpf.usermodel.XWPFDocument.onDocumentCreate
I guess some jar or classes are missing.
Any suggestion would be useful.
Thanks in advance
You're missing some jars. In order to read Word 2007 files using POI you also need the following libraries (they're all available in the archive you download from the official Apache POI site):
poi-ooxml-schemas (the one you're getting the error about)
xmlbeans
dom4j
stax
According to the official website, dom4j and stax are no longer needed but I found I had problems when I didn't add them.
Unfortunately, you're bound to discover that adding all of these libraries will result in a Dalvik dex error (an Android classes.dex can hold up to 64k of method declarations, which you will cross). The "official" explanation for this is that POI is simply not designed for Android. Unfortunately I have not been able to find an easy, manageable solution for that problem (there have been attempts, some partially successful, of porting POI to Android, but they're too cumbersome for my taste). I solved that problem by sending the Word 2007 files to a remote server, converted them to the old format and returned to the mobile device to be opened by POI.
I am in the process of learning to create google-app-engine as well as to generate Endpoint client library(for Android) from my app-engine application.
So far I have done the following things
Step 1 : Create Endpoint API : Complete
I have followed the instructions given here(using Maven) and have successfully deployed the app-engine application
https://developers.google.com/appengine/docs/java/endpoints/getstarted/backend/
Step 2 : Generate Client Library(for Android) : Getting ERROR here
I have followed the instruction here
https://developers.google.com/appengine/docs/java/endpoints/gen_clients
I gave the following command from the root directory of my app-engine application
endpoints.sh get-client-lib Greetings
But getting the following error
Dec 16, 2013 5:47:43 PM com.google.apphosting.utils.config.AppEngineWebXmlReader readAppEngineWebXml
SEVERE: Received exception processing ./war/WEB-INF/appengine-web.xml
com.google.apphosting.utils.config.AppEngineConfigException: Could not locate /Users/raj/Documents/workspace-maven/helloendpoints/./war/WEB-INF/appengine-web.xml
Give below are my questions,
Is this command execution right?
endpoints.sh get-client-lib Greetings
In the documentation in google ; the second argument is
specified as 'get-client-lib' I have given the same name while
executing the command ; is this right?
As you can see in the error ; it describes ; file -
helloendpoints/./war/WEB-INF/appengine-web.xml could not be located.
The file is indeed available in my application, but is located in a
different directory(indeed in 3 locations) ; What should I do here?
./src/main/webapp/WEB-INF/appengine-web.xml
./target/generated-sources/appengine-endpoints/WEB-INF/appengine-web.xml
./target/helloendpoints-1.0-SNAPSHOT/WEB-INF/appengine-web.xml
The documentation suggest me to edit 'web.xml' file. But the file is
available in 3 location and am not sure which one I have to edit(I
have edited the file in 3rd location)
./src/main/webapp/WEB-INF/web.xml
./target/generated-sources/appengine-endpoints/WEB-INF/web.xml
./target/helloendpoints-1.0-SNAPSHOT/WEB-INF/web.xml
I am finding it quite difficult to resolve this issue ; as there is no other documentation (or) examples available in web other than the Google official documentation.
Would appreciate if some-one can help me to resolve this. Thank you.
you just need to make sure that, you directory exist and that you have the required files into the directories. I can also use the maven goal to make the generation, I read a complete article on the issue here. http://thenavigatorme.blogspot.com/2014/05/how-to-resolve-google-cloud-endpoints.html
Hope this helps.
