Android :: Create BKS Keystore File For SSL Support Of Web Server And Handshake Process

Nov 9, 2009

I'm working on a litte HTTP server application for the Android. Now I like to secure the communication by using SSL. But I got stuck by creating a suitable keystore file. Searching the archives I came to the conclusion that it will be best to use a BKS type keystore since all other keystore types (like JKS) are not supported on the android.

Unfortunately I can't figure out a way to setup the keystore file. I tried OpenSSL - wrong keystore format. I tried the keytool from JDK - right keystore format but it doesn't support BKS keystores. I tried the Keytool IUI - I could create a BKS type keystore but it alwais ends up in an InvalidKeyException "Illegal key size". No matter if I try to create a new certificate or import it from a JKS keystore. (I tried to create the RSA ver.3 certificate with a key size of 2048 and 1024 bits.) How do you create BKS keystores?

For completeness here's the code I trying to use for loading the keystore:..............................

Android :: Support Of JKS Keystore

Nov 13, 2009

I am having Java SSL based server and I want to connect android SSL supported client to it. My keystore in Java is JKS, but android says no JKS implementation found. It supports BKS. Is there any way to have JKS support for android ? If not then how can use BKS in Java. I am trying using PKCS12, but documentation says using PKCS12 for trustanchors purpose is not supported.

Android :: How To Create BKS - BouncyCastle - Format Java Keystore That Contains A Client Certificate Chain

Oct 31, 2010

I'm writing an Android app that requires SSL client authentication. I know how to create a JKS keystore for a desktop Java application, but Android only supports the BKS format. Every way I've tried to create the keystore results in the following error:
handling exception: null cert chain

So it looks like the client is never sending a proper certificate chain, probably because I'm not creating the keystore properly. I'm unable to enable SSL debugging like I can on the dekstop, so that's making this much more difficult than it should be.

For reference the following is the command that IS working to create a BKS truststore:
keytool -importcert -v -trustcacerts -file "cacert.pem" -alias ca -keystore "mySrvTruststore.bks" -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath "bcprov-jdk16-145.jar" -storetype BKS -storepass testtest

Here is the command I've tried that is NOT working to create a BKS client keystore:

General :: How To Crack Keystore File

Feb 9, 2012

I developed an Android game with a colleague and uploaded it to my Developer account. I created an update and it's ready to upload, but I realized I can't use the same package name because I don't have the password for the keystore because it was created by my colleague and he no longer works with us. The current version of the game has already gotten tens of thousands of downloads and many good reviews, so I want to be able to keep the same package name so I can upload the update as an update, instead of uploading it as a new app. Is there any way to crack the keystore file without knowing the password?

Android :: Marketplace Error - Server Could Not Process Your Apk - Try Again

Feb 16, 2010

I have an updated apk - tested successfully on various devices and simulator instances - with the following manifest:


When I post to Android Marketplace as an upgrade to my existing 1.0 app, I get the aforementioned ambiguous message: "The server could not process your apk. Try again."

I just tried to upload the same file again. Now I get a new message:

The new apk's versionCode (2) in AndroidManifest.xml must be higher than the old apk's versionCode (2). The server could not process your apk. Try again.

So Marketplace did get my upgraded apk after all? (The very first accepted apk's versionCode was 1, so this update was of course bumped to 2.) Confused ...

Bumping it up to 3 and trying again. Surprise surprise, I get the original "could not process" error all over again. Going in circles.

If I exit and re-enter the Marketplace page, now it shows that the app has been uploaded! Except there's no app icon. Curiouser and curiouser ... and this is all happening with a cache-cleared (standards-friendly) browser to boot.

Android :: Whenever Upload An App - Message - The Server Could Not Process Your Apk. Try Again.

Mar 26, 2010

Has there been an upgrade to the market that changes the minimum requirements for an app? I have taken a couple months off and now whenever I try to upload an app, I get the unhelpful message "The server could not process your apk. Try again.". This happens even when I upload the exact same apks that I have uploaded before and ones that work fine with adb push onto devices.

Android :: When Upload A New APK Version - The Server Could Not Process Your Apk Try Again

Nov 15, 2010

Since this morning, I've been getting the error in the subject when I try to upload a new APK version to my Market Developer Console. At first, I figured it was just a brief server outage, but not since it's gone on all day. I also suspect it's only affecting me, since I've seen no other mention of it on this group. Well, I'm mentioning it now.

Anyone come across this before? I've released enough APKs that I'm quite familiar with the Console; while that doesn't rule out a stupid mistake, of course, I don't think that's the case here. Obvious possibilities that I think I HAVE ruled out: I've confirmed that it's the correct package name, and that it's signed with the same key as it always has been. Beyond that, I'm not sure what to consider.

I have also contacted Market Support, with no response as yet. And I did notice that this morning was the first time the "Draft application" feature became available on my Console; not sure if that's relevant, but coincidences are suspicious.

Android :: Does The Dalvik File Format - .dx - Support More Instructions Than Java .class File

Apr 17, 2010

Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?

As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

Android :: Android Create Activity Within Process?

May 26, 2009

I'm developing a photo editor application. It will launched by android.intent.action.EDIT intent. I made two application to emit that intent. I found that two instance of my photo editor activity is created within the same process which is named as my activity. But there is a singleton class used in my photo editor activity and that two activities use the same singleton class instance which break my application logic. I wonder if there is any way to let Android create my activity within the process which the launcher activity lies in? So that the two instance of my photo editor activity can be separated into two different process. And so they can reference to different instance of.

HTC Incredible :: WAV File Player - Player Does Not Support This Type Of Audio File

Every time someone leaves me a voicemail on my home phone number, VOIP home phone voice mail box sends me the voicemail as a .wav file attachment. When I try to play this .wav file the phone refuses, saying "Sorry, the player does not support this type of audio file".

So, I take it the .wav files cannot be played on Android phones. Has anyone found a workable and simple workaround to this yet?
