I cannot find any documentation that specifies the algorithms that I can specify in getInstance for Cipher. Is there any around? Specifically, I am looking for support for the RC4 cipher.

When I try to use code similar to that in http://www.javablogging.com/dynamic-in-memory-compilation/ I find the classes will compile but get a java.lang.VerifyError on execution the class uses javax.tools.JavaCompiler and javax.tools.ToolProvider and one supporting class uses javax.tools.ForwardingJavaFileManager and java.security.SecureClassLoader.Any bright ideas - is it OK to use a class loader extending java.security.SecureClassLoader?Are these packages unavailable on the android and if so is there a list of unavailable packages

View 2 Replies View RelatedI am developing a mobile application that involves complex image processing operations. The app is designed in Java while the core image processing ops are implemented in native code, and compiled using the Android NDK.Now, I know that native code will *not* yield any significant performance improvement over Java code, and that the NDK purpose is only to support re-use of code libs (or to quickly integrate legacy code).are there any resources/tips-n-tricks/white papers/ samples on optimizing image processing algorithms for Android? To be even more specific, I am looking out for optimizing memory operations (cache misses, memory stalls, etc.). I profiled my application code and came to the conclusion that memory issues are causing the *maximum* performance penalty. (Nothing surprising over there, it is expected, but just verified with profile data as well).

View 2 Replies View RelatedIn Android, I could see 2 BitBlit functions defined in skia and libpixelflinger libraries.
1) S32A_D565_Opaque function in external/skia/src/core/ SkBlitRow_D16.cpp has one implementation
2) scanline_t32cbl6blend function in system/core/libpixelflinger/ scanline.cpp has another implementation
Both implementations look different. Please help me understand the rationale behind these algorithms and the reason for having two different implementations/algorithms.

View 2 Replies View RelatedI'm an android developer trying to use the javax.crypto package to encrypt/decrypt my SQLite database backups when I put them on the SD Card.That way, they can't be read while they're in the publicly accessible file system.I can encrypt/decrypt the file just fine, but I have no idea how to tell if the user input the right key or the wrong key. An incorrect key just returns a more jumbled file. I need a way of validating the user's password without storing it on the device (since they could be importing to another device).How can I check to see if the file has been successfully and correctly decrypted?

Just couldn't find anything regarding the purpose of android.opengl classes anywhere on the web: they seem to be copies of javax.microedition.khronos.opengles - just with static vs member methods.
So is there any special meaning in using them instead of j2me classes: are they supposed to be faster, have additional functionality, simpler to work with? I think of using them instead of passing that gl reference all the time.

I'm trying to build a app that uses the SmsMessage class but there are two versions depending on the API level of the device:
android.telephony.gsm.SmsMessage (deprecated for 1.6 and above)
android.telephony.SmsMessage (the new class for 1.6 and up)
I want to target 1.5 and yet have the newer class (android.telephony.SmsMessage) run on devices with 1.6 or higher. How do I do this?

View 2 Replies View RelatedThere is an open issue with about 100 people watching it and 80 comments on it which nobody seems to care about it is http://code.google.com/p/android/issues/detail?id=1580 and it talks about Hebrew support for android phones. The current situation is that people need to root their phones to get it which is simply a ridiculous situation. This issues has been left unattended for a very long time and all that's really needed is to replace the system fonts with fonts that support hebrew. This has been done by Samsung on the Samsung Galaxy and has been proven as working and did not change the font of the system when viewing English. My question is, why is it that Google can't take the time to integrate a change that already exists in a branch of the OS into the trunk and thereby allowing many other people to enjoy the OS? This affects not only Hebrew, but Arabic and many other languages, what's the point of an open source OS if the project progresses so slowly?
