I am looking for someone able to develop this library:
Our need is to connect 100 BTLE tags to a single Android phone running our app.
This is out experience on this issue:
Some producers (Samsung) has written specific BTLE libraries for Android 4.2, we have never tried them.
Google, starting from 4.3, started implementing BTLE, so any previous release has been superseeded and any other producer
libraries have been abandoned.
We have tried the Samsung S3 with Android 4.3, we got a stable connection but with a 7 bonded tags limit.
On Samsung S4 with Android 4.3, the connection is not stable. Bonding would fail often and it was difficult to connect.
Unfortunately the Samsung source code is not availalbe.
We then tried Nexus 4 and Nexus 5, but on Android 4.4 the maximum bonded devices is down to 4, which is even worse.
Since the stock Android (on Nexus) do have source code available, our idea was to rewrite a simplified version of the BTLE library provided with Android (bluedroid) which fix this limit of bonded tags.
We can use any other 4 or 5 inches phone.
What we need is to be 100% sure that the person who take this project do fully understand what we require of him and is capable to complete it.

It looks like British TV network Sky is starting to catch up with the the pace of Android OS upgrades. Today it's launched a new version of its Sky Go mobile TV app, introducing support for 14 new devices along with Android versions 4.1-4.2.1 (Jelly Bean). Today's update brings Sky Go to a wider audience, after an update over the summer first opened it up to ICS phones.
From our own device history, we can confirm that Sky Go supports the Nexus 4, Nexus 7, Galaxy S3 LTE, Galaxy Note 2, Sony Xperia T, LG Optimus 4X HD and Jelly Bean'd Galaxy Nexus, amongst others. Notable exceptions include the HTC One X+ and One S, which unfortunately remain unsupported.
Other changes in the new version of Sky Go for Android include improved navigation and various other UI changes.
so the Nexus 4 and 7 get it but no nexus 10 ?
surely this is some kind of cruel wind up?
I know this is a big joke, im new to the android platform and just purchased the Nexus 10 and Sky Go is the one thing lacking from it right now. So just to add salt to the wounds they update the app but dont make it compatible with Nexus 10. My take onit is just that there lazy!!
I think the Nexus 7 is the first Android tablet supported by Skygo so that is a milestone and the Nexus 10 is sure to follow.
Has anyone tried simply installing the apk?

Yes, it looks terrible and won't let you view channels as the device isn't compatable..
As a general question on the availability and delay of Samsung upgrades; how good is Samsung in making the latest Android OS available to legacy devices? Do they support one, two or more generations? I know that there are sometime HW constraints that prevents the owner from upgrading, but suppose that the HW supports the latest OS version?
The reason for asking is that I currently have Apple and I might consider getting an S5 but at least in regards to OS upgrades, i am a little spoiled as Apple makes the latest OS available to all devices.
My last and my current smartphones were nexus devices. Since google revealed the pixel I thought about other smartphones. But I don't like update speed from non-google companies.
How difficult would it be to convert the current Stock Android (for example android 7) to the Huawei P9, OnePlus 3 or the Samsung Galaxy S7 or any other top device.
And how much time would you need to support also the curved Display from the Samsung Galaxy S7 Edge or to support the notification button from the OnePlus 3 and the fast charging.
To myself: I would say that I am quite good at Java but not in a professional way.It is just a hobby.
In general: If I buy the latest smartphone of a company like Huawei, Samsung, OnePlus or LG would it be possible to convert the current Android version to my device? How much time would I need for that if I only want the Stock Android functions and the fingerprint sensor (Cyanogen features are not needed) and how long would I need if I also want to support the device specific features like a pen or a curved display?
How dangerous would that be? Breaking my device would be pretty easy right?
If that is possible how do I convert the Stock android to my device?
Thanks a lot

short answer: very difficult. Huawei uses custom SoC from HiSilicon, and the specs for these chips is not published. similarly for Samsung devices using Exynos chips. Samsung phones running Qualcomm have a better chance.
if you want to learn to build AOSP (or something like CM), start with the AOSP documentation, then the CM wiki. Or go to the device forums here and check if someone has already started progress. for Huawei and Samsung (exynos), it's a long journey.
it goes well beyond knowing Java.
relatively speaking, modern devices are tough to permanently brick as long as you don't touch the bootloaders.
Thanks for the answer
hello iwas just wondering if ther e could be abring up ofan android 10 port for nexus 9. as hte are other port bring up for ohte older devices and tablets. Jus twondering if its possible ornot.
Vartom had commented that there are driver issues with the Nexus 9 as it is and making it work fully with Android 8.1 is difficult as it is. It's likely it would be even more difficult to get things working with later versions without Treble
It would actually be fairly easy to build a recent AOSP for N9. In particular, the master branch of AOSP has some really cool pieces in place -- recent version of mesa3d, drm_hwcomposer, gralloc_gbm.... the only parts of the N9 that likely would create trouble would be the cameras. But you can't really use the cameras on a tablet anyway because you look like a moron doing so.
Note that Treble is NOT a requirement for building AOSP for N9. Previous poster is confused because its a requirement for devices that FIRST SHIP WITH certain versions of Android, in order to qualify for inclusion of google blobs. This requirement does not apply at all to N9 for THREE reasons;
1) No need for certification because you aren't trying to sell it.
2) N9 first shipped with Android 5.
3) Nothing applies to custom firmware.
Or now Android 11 for Nexus 9 ???!!!!
Tab S6 Lite is on the list.. though haven't seen our beloved unit announced.
Anyone know anything?
Usually i am not that fussed as there is always Custom ROMs available to keep it up to date.. Though custom ROMS don't seem very common for this device!
Android Authority says yes!
