I want to use DTLS (on OpenSSL) using JNI on Android 2.1/2.2. Can someone help me get started (tutorials, howto, pointers etc) with building OpenSSL for Android (2.1/2.2) using the Android NDK?

I've got a problem with my application when I make a number of requests using the HttpsUrlConnection class.
My program makes the first request using the HttpsUrlConnection class to retrieve a file. It then makes a second request to the same server to retrieve a different file. What happens however is that periodically I'm getting a -1 HTTP response code on the connection.
When the failure occurs between the two requests I see the following line of trace in logcat:
D/OpenSSLSessionImpl( 699): Freeing OpenSSL session
This seems to happen fairly consistently. If I retry the second request after it has failed it generally works and I get the requested file from the server.
Note that if I don't see the OpenSSL session being freed the second request works fine the first time.
Some other information:
1) I'm not calling disconnect on the connection
2) I'm don't always read the entire file from the server after the first request
3) I always close the InputStream in the event that I get an InputStream on the first connection
How to prevent the OpenSSL session from being freed.
i need my app to support 1.5 and above. i noticed that if I create my build.xml file using --
c: oolsandroid2.0r3 oolsandroid update project --name MyProject -- path C:MyProject --target 2
it complains about my resource directory names "res/drawable-hdpi, res/ drawable-ldpi, etc... res/layout-large, etc..." saying "invalid resource directory name".
If I use 1.6r1 tool set c: oolsandroid1.6r1 oolsandroid update project --name MyProject -- path C:MyProject --target 2
Everything works fine.
If I use target 3 (1.6 and above) c: oolsandroid2.0r3 oolsandroid update project --name MyProject -- path C:MyProject --target 3
Everything works fine. So, do I basically *have* to use 1.6r1 to build for 1.5? And does that mean that those special directory names will only work on 1.6 and above?
I've G1 dev phone. Earlier I upgraded it to 1.5 using HTC website. Now I want to customize (make some changes to ) source code and keep the changes running on G1 phone.

I would like to create a library and include it in an application by specifying something like <uses- library android:name="com.foo.bar" /> in the manifest (just like maps) and have an Activity that can be inherited from like the MapActivity. How can one create and build a library like this?

I even changed ant to ant.bat at one place, android to android.bat at two places in ruby script. I also set target_id = 1 which is for 1.5 sdk.
When using an Android-generated ant build file, the file references your SDK installation via an sdk.dir property inside the local.properties files which is generated by "android update project -p .".
The comments in build.xml suggest that local.properties should NOT be checked into version control.
BUT, when you run your build from Hudson, it does a fresh checkout of your code from version control, hence local.properties does not exist and subsequently the build fails without sdk.dir being set. So its kind of chicken and egg problem. As a workaround I have checked local.properties into version control for now (nobody else will use it) but I was curious as to how other developers had tackled this problem ?
Solved this by following the instructions at http://www.mail-archive.com/android-porting@googlegroups.com/msg01340... Also realised - that looks like a more appropriate mailinglist too :)
View 2 Replies View RelatedI'm tinkering around with trying to build a speedometer using only the accelerometer for use when I go snowboarding. I can read values from the accelerometer but I'm not sure how I would derive the velocity. I was thinking of taking the square root of (X^2 + Y^2 + Z^2) where X, Y, and Z are the values reported by the accelerometer in each axis but that only would only give me the amplitude of acceleration at any given instant. I could multiple that by the sampling frequency to get my instantaneous velocity but this approach fails when I'm moving at a constant speed.

I have no idea about Ant and its functioning so it would very appreciable if minute details are also provided.

View 9 Replies View RelatedI am doing a project where we have to use the Android Terminal Emulator. I downloaded the the Jackpal Android Terminal Emulator from github and using the instructions in the document to build the terminal emulator.

I am having trouble installing the package in the first step itself, i.e. building the ndk shared libraries.
According to the instructions provided:
Build the shared library:
cd <the-android-terminal-emulator-directory>
<path-to-the-android-ndk>/ndk-build
Accordingly, I typed the following in my cmd
C:>cd androidterm

I got the following error message:
'android-ndk-r6b' is not recognized as an internal or external command, operable program or batch file.
I am still learning Android and have never worked with the command line before. Is it a problem with the way I have typed the command?

We're thinking about building light and paid versions of our app for the Market. But I am not clear what we need to do, or how to do it. (1) Do we definitely need the two versions to have different package names for the two builds ?It seems logical to do it that way, but I have not found a clear answer from Google to that question. Though I have found several people asking the same question. 2) Is there any support in Eclipse for building two similar apps with different package names from the same java and xml files ?In most of the IDEs I've used, it is a doddle to define multiple build targets for one project, but none of those mechanisms seem to be present here. And, the package name is embedded in every java file, as well as in many places in the manifest, leaving me without a tidy way to build to alternate package names.Is there a tidy way to build multiple version ? Or are we really going to end up copying the whole codebase and search-and-replacing the package name.
