java android serialization jackson bson
My goal is to deserialise a BSON array of documents on Android. When the outer array is anonymous the deserialisation fails (trying to deserialise to CustomObject[].class). When the array is wrapped in an object with a key containing the array it works (deserialising to WrapperObject.class).In JSON the object would look like this:[{“id”:….},{“id”:….},{“id”:….}….]According to the BSON Specification the BSON array is a regular BSON document with integer values for keys. In other words the

I have a project that uses two independent Android libraries. Each of them contains Android support package, so that ant build fails on ‘dex’ step:[dx] UNEXPECTED TOP-LEVEL EXCEPTION:[dx] java.lang.IllegalArgumentException: already added: Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat;[dx] at com.android.dx.dex.file.ClassDefsSection.add(ClassDefsSection.java:123)[dx] at com.android.dx.dex.file.DexFile.add(DexFile.java:163)[dx] at com.android.dx.command.dexer.

android webview scrolling android-4.4
I am seeing some unexpected behavior when using a WebView in Android 4.4 (build target 18). One one page in particular we have some edit text fields, and to get the soft keyboard to pop up appropriately, we had to use a code snippet similar to the ones described here: https://code.google.com/p/android/issues/detail?id=7189webview.setOnTouchListener(new View.OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {switch (event.getAction()) {case MotionEvent.ACTION_DOWN:cas

android webview
I’m developing an Android application that uses a WebView to display the login page for Facebook. The page loads beautifully, and I’m able to select the username/password textboxes, but typing in them will not work. That is, they definitely have input focus (they have the orange focus highlight box and a flashing cursor), but typing in them does absolutely nothing. I’m not certain, but I think maybe the form buttons are also playing up – they appear to be simply refreshing the page, rather than

I want to add a subview in the top of my view, I have to recalculate the origin y value for all of other views and re-position them to leave space for the new added view.It is very boring, as I know android have relativelayout or linearlayout can help automatically do that.How to solve this problem easily in ios development?

android sed edify
When you alter any Android system files (apps, libs, conf, recovery etc..) any Over-the-Air (OTA) update will fail, because the updater script checks sha1 hashes and the installer aborts if there’re any mismatches.Specifically it looks somewhat like:ui_print(“Verifying current system…”); apply_patch_check(“/system/app/BasicDreams.apk”, “3cd7485ba69bc6fb6a5bcb78ed2a331c68ffe3eb”, “9c43bf95b1eaed097ad74b15b2ba232d69992175”) || abort(“\”/system/app/BasicDreams.apk\” has unexpected contents.”); ap

c++ visual-c++ gcc static-libraries
I’m compiling a static library that contains mainly templated classes. When this is compiled using gcc, the resulting .a file is around about the 40Mb mark. This is pretty big, but not entirely unexpected due to the amount of templating going on. However, when I compile the same code using VS2005, the resulting .lib file is coming in at (wait for it!) 575Mb..Now, before I get burned, I have seen: How can I get my very large program to link? and this is useful for understanding that templates are

I’m trying to automate the process of accessing libraries in the framework I use (CodeIgniter) but am running in to some issues.Codeigniter currently loads libraries like this:$this->CI->load->library(‘name’); $this->CI->name->method();Needless to say that this is a whole bunch of code for something that could be achieved with far less.I would like to access my lib like this:_Lib::name->method();The _Lib class will then take care of loading the right lib (or directing the lo

I have a class that wraps a file handle:class FileHandle {HANDLE hFile;TCHAR name[256]; public:LPCTSTR getName() const { /*(query system for name)*/ return this->name; } };I have come up with a design choice: Since I will be querying the file name often, in order to minimize heap allocations which would happen if I returned std::wstring (I have repeatedly seen that this is a bottleneck in my programs), I have instead decided to keep a name field inside the object itself, and just return a po

I am trying to make a static binary on Subsurface on MacOSX, so that we can provide a simple binary download. I’m clueless as to solve the problems I get, but that might just be because I suck at C.Here’s what I do.

dll static-libraries
I know very little about DLL’s and LIB’s other than that they contain vital code required for a program to run properly – libraries. But why do compilers generate them at all? Wouldn’t it be easier to just include all the code in a single executable? And what’s the difference between DLL’s and LIB’s?

c++ mingw visual-c++ compatibility static-libraries
I have compiled several libraries with MingW/MSYS… the generated static libraries are always .a files. When I try to link the library with a MSVC project, Visual Studio throws ‘unresolved external symbols’ … It means that the .a static library is incompatible with MS C++ Linker. I presume it has to be converted to a MSVC compatible .lib file.Either .a and .lib are just AR archives of .o or .obj files, so is there any way how to use MingW compiled libs in a MSVC project? Or do I have to compi

c++ c windows dll static-libraries
We have an application written in C/C++ which is broken into a single EXE and multiple DLLs. Each of these DLLs makes use of the same static library (utilities.lib).Any global variable in the utility static library will actually have multiple instances at runtime within the application. There will be one copy of the global variable per module (ie DLL or EXE) that utilities.lib has been linked into.(This is all known and good, but it’s worth going over some background on how static libraries be

iphone objective-c static-libraries categories
Can you guide me how to properly link static library to iphone project. I use staic library project added to app project as direct dependency (target -> general -> direct dependecies) and all works OK, but categories. A category defined in static library is not working in app. So my question is how to add static library with some categories into other project? And in general, what is best practice to use in app project code from other projects?

I have this app (Only one activity) that use some android UI and some native C++ lib to do OpenGl drawing and calculation.It seems like the activity creates some “binder thread” on it’s own, and I’m pretty sure it causes some corruption amongs my native calls.What are the binder threads ? Can they be removed or merge into one ?
