Work has begun on the following coins:

1.  Darkcoin - X11, Dark Gravity Wave - https://darkcointalk.org/threads/android-wallet.393/
2.  Myriadcoin - 5 concurrent hashing algorithms.

These provide different challenges.

We are currently considering working on Coins that use X11 and the Dark Gravity Wave.  Someone has to write this code and it might as well be us.

As of today, we have successfully tested the X11 algorithm (in Java) and the Dark Gravity Wave (1 and 2). 

Nothing has been done on native versions of these for android, yet.

Neither is it a quick thing to fork the bitcoin wallet to another coin.  After that there is much maintenance required to keep the app functional given all the updates that coin devs push through.

At this point, prices are 3 to 4 BTC.  Howeve, that price is another way to say we are too busy to take on more projects.

Wow.. 3 to 4 BTC is not cheap!

What are the prices for getting an Android Wallet created? I know Peercoin has a $15,000 bounty or so on an Android wallet.

Thank you for the article at cryptoarticles.com.

In the month of March many other developers have launched android apps.

Many have requested wallets for new coins and others from older coins, but we do not have time to work on anymore than the five listed in the OP.  We are currently trying to finish these apps and improve them in terms of speed (especially those that use the Kimoto Gravity Well) while updating from upstream (bitcoin-wallet upgrades and bug fixes).

However, we would be willing to make an exception to that rule if a coin has some innovative feature requiring java code that may not exist and the price is right.  We will, however, continue to help other developers with questions on getting other coin apps running.  We have helped up to four other developers.  That is a good sign as there are perhaps 10 or more groups of developers out there that can do android apps, where 8 months ago there were perhaps only two.  Good luck.

We have added native processing for the KimotoGravityWell to the Franko and Megacoin Wallets.

The Kimoto Gravity Well has been optimized (from Java to a Java/C++ hybrid) and now runs up to twice as fast.

It will be released in Megacoin and Franko soon.

How difficult to add support  Scrypt-jane and Scrypt-Adaptive-Nfactor?

We don't have the answer for this right now as we haven't worked with these algorithms.  Native support will be key.  These hash functions really wear down the batteries of android devices.

How do we begin the process of having you guys make a TrollCoin Android Wallet?
Thanks!
You can post a question in our forum and hopefully a developer will take on the job.  Currently I am too busy to take on more work.

Many are asking for Android Apps for new or older coins that use the Kimoto Gravity Well.  This difficulty adjustment may work wonders for halting the strip mining of multipools, but it is not good for Android device battery long longevity or for sync speed with the blockchain.

There are three parts of the KGW code.  The first part is the rewind (retrieving the previous block header), the second is difficulty calculation math with 256 bit integers and the last is some floating point math for other calculations.  These three parts are part of a loop that repeats a certain number of times for each block.  About half of the time involved in calculating the difficulty is retrieving the previous block information.  Sometimes Megacoin needs to do this between 144 and 4000 times for each block.  About 40% of the time is doing a subtraction, a division and an addition using 256 bit integers (Java BigInteger is slow).  Lastly, the remaining 10% of the time is doing some floating point math. 

Currently, we are looking into getting the 256bit integer math handled Natively (machine code) instead of interpreted Java.  Next will the the stepping back through the block chain.

If it is possible,create please Litecoin android wallet.
Thank you.

The Litecoin Wallet already exists, based off the latest Bitcoin Wallet code:

Have you got SHA-256 android wallet.?
Because all list of your projects is SCRYPT coins.

SHA-256 coins are possible also, the only difference is one line of code.  Even scrypt coins use the double SHA-256 for the hash values of blocks, transactions and merkle-roots.

If it is possible,create please Litecoin android wallet.

Are there any other sha-256 wallets I can look at? Any alt coins have one?

No.But you can make it by changing one line in the code.I will post it later
