I want to encrypt individual contacts stored by the Contacts application on Android based on user's preference. So, I am thinking I'll have to hook/extend the Contacts application before the it stores data into the database and decrypt it when the user wants to view it. Also, I am assuming I will have to store the key for encryption in a file.

Hi,
I'm planning to use my website to provide updates for my android application whenever the user decides to perform an update( in case there is one available) . I'm thinking to use http requests for the communication between the user and the server, so whenever there is a new update the server sents back to the user the link to download the apk of the update through the android browser. So far I think it should work !?!. But once I have the apk of the new update on the card ,and the installed old version of the application how do I actually perform the update ?

I can either create my own Dialog class (which, to me, is more clean and organized), or I can use AlertDialog.Builder (which would be done inline, and funky looking)... What are the positivies and negatives of either implementation?
View 1 Replies View Relatedi've been looking for an application for merging the SIM contacts with the GMail contacts but can't seem to find any. Does anyone know if such an application is available? The result now is that i have a huge list of contacts (GMail + SIM) with many duplicates and information spread around different entries. Remark: i'm not sure if this question belongs here, but i had to choose between the G1 T-mobile and this forum.

View 3 Replies View RelatedI would like to perform a certain operation every time a user adds a new contact in the Android Contacts application. It would include using the new contact's information.Is there an easy way to do this? Is there some event that can be listened for or do I have to extend the Contacts application itself? Or should I just think of some other approach if this is not feasible.

'Gallery Private' in the market looks like it may do this. Does anyone have experience with this app? Does it only encrypt pictures and folders?
'B-Folders+sync' looks like it only does contacts and notes. I may need a combination of them both.
Makes me sort of wish there was a BitLocker-esque app available.

View 3 Replies View RelatedI am developing an app that uploads files to an FTP server, and the app will have the ftp user name / password in the code. I'm investigating making the FTP user name and password as secure as possible (including an encrypted value for each in a strings.xml and decrypting in the app when it needs to connect to the FTP server).
My concern is this is not actually secure at all, it seems someone could unzip the .apk, decompile it, view the strings.xml and java code that decrypts it - and thereby obtain the ftp login info.
So my question is.. am I approaching this wrong way? Is there a standard method of ensuring passwords that are hard coded into an app can be secure? (note - in this case this is not a password a user of the app would enter, the FTP password is universal to all that install it so it is included in the app).

View 2 Replies View RelatedI have finally - after days and days of agony - figured out that I need two forms of encryption for my Digital Signatures Project. The first will will be symmetric (AES) and will encrypt the license data and the second will be a asymmetric (RSA) an will encrypt the symmetric key. Can someone give me pointers on the best methods to use for Android.
For the public/private keys I am using: "RSA/ECB/PKCS1Padding"(I head ECB is bad so what should I use?, what about the PKCS1Padding - shoudl I be using PKCS5Padding?)
For the symetric keys I will probably use: "AES/?/?" (What mode and padding should I use?)
The provider: "BC"
RSA Keysize: 1024 (I tried 2048 but it didn't work for some reason)
AES Keysize: ?

View 4 Replies View RelatedI'm running into difficulties overriding an ArrayAdapter to be displayed in a ListActivity. The ArrayAdapter is filled asynchronously. What I'm trying to do is add a special "sentinel" object that sits at the beginning of the list to show the progress of the computation. Ultimately this may be a progress bar, but right now I am just using a TextView as a placeholder. The problem is that the sentinel seems to get inserted multiple times into the list - not just once at the beginning. It *seems* to be appearing once per "page" of list data (so if 8 list items fit on the screen, my sentinel appears as the 1st, then 9th, then the 17th, etc..), but that interpretation may not be accurate. While maybe not how ArrayAdapters were intended to be extended, I thought something like this should work by simply overriding getView() to show my custom TextView for index.
