Need a software to copy files to multiple devices at the same time

Hello, is there a software where can I copy several files folder to a group of same android devices at the same time? or scheduled time or one after one??
Those several files are appr. 1GB so I want to transfer them to multiple devices thru a wan (intranet)..Is there any software to do this task??:D
Android version : 4.2 or 4.4

Is it better to perform the same calculation multiple times?

When optimizing onDraw of a custom view, I found alot of object allocations in the onDraw method of that library.

What I don't know is if it's more efficient to calculate the same calculation multiple times or allocate one calculation to an object an reuse that object?

I want to hear your opinion about this, since it will be allot of work to change this "property" of the code.

Thanks,

Tim

Multiple earphones

Hello, I bought z:ero digital earphones which connect with the micro-USB port to my phone. I tried to connect at the same time my conventional earphones from 3.5mm jack in order to have two sets of earphones playing music. The problem is that as soon as I connected the standard earphones the USB ones stopped playing music.
Is there any way to force both sets play music together?

[Q] SOD On Multiple Roms- Hardware Problem?

New to posting here but I have been lurking for quite some time. I'll keep it brief here.

Suddenly, since flashing a 5.1.1 ROM, my N5 has been experiencing a sleep of death issue. Namely, once the screen turns off, it does not respond to anything. Pressing the power button does not wake the phone, and neither does plugging it in. After some time (~1 minute), the phone will reboot itself.

I know that this is not an uncommon issue, but the reason I have been forced to query the forums is because I have been unable to solve it by flashing ANY other rom. I've tried 5.1.1, 5.01, 5.0, and 4.3.3. I've searched and searched these forums and others to no avail. I've done countless restores to stock firmwares and 3rd party roms alike, removed apps and added them again, but nothing has solved my issue. I'm beginning to wonder if it is a hardware problem- that would be truly tragic.

I've pulled a kmsg but cannot attach it here as I have never posted, so I pulled a line that I believe is of interest, and would really appreciate it if you guys would look over it and tell me what you think.

Thanks!

Caller report echo on multiple ROMs

I posted this in the Sprint note 3 section but realized that was silly as I have confirmed this is not a Sprint specific issue.

My callers report an echo. I sound fine to them and everything sounds fine to me; They hear their voice echoing back.

This does not happen running stock TW. either 4.4 or 5.0
However EVERY ROM I try, I get it. What gives?

ROMs tested and confirmed to echo:

(All on 5.1)
Cm 12.1
AICP
Dirty U.
Temasek

I'm UTD mainly on them all
(since mid-late July)
Doesn't matter which nightlies I try ect.

Most of the time you read about these issue they get chalked up to the phone case. This is clearly not the issue here.

I'm a newb to romming (is that verb?) Could it be by chance my gapps? As I do flash the same gapps on all...

This sucks because the stock TW (rooted ect) actually has more problems than anyone of these ROMs, but not the voice problem which is to great to bare.

On the AICP G+ group other hlte users reported it (non sprint)
Some say it comes and goes.
I don't voice much so its a little non issue for me but grand in it's effects.
FWIW This happens on landlines as well as mobile networks.
I read that this was an old CM issue fixed months ago....But I didn't flash CM12.1 until mid July nightly.

-Thanks

How to merge multiple instances of a contact within one Google account?

Problem:

When I tap on a contact (via the dialer) often times as I scroll down the same information duplicated (four birthdays in a row, for example). Here's the issue - you see multiple same birthdays.



When editing a contact in the Contacts app (I have a non-rooted Note 4 running stock Lollipop) it pulls up all instances of that contact, and often duplicate content (multiple instances of a birthday, same phone number, etc). This is the native contacts app on my phone. I don't know if this is pure Android app or a Samsung skin



I have only added my one Google account to Android (e.g. myemail at gmail dot com). But when I edit a contact I still see 3-5 "google" instances of that contact. See below. When I edit this contact, you see the numerous "google" headers - these are the different instances of the same contact.



Any idea how to merge all this so that I don't have multiple instances of the same contact and duplicate info for the same contact?

Thanks - I consider myself pretty bright, but this has perplexed me about Android for YEARS!

How to install multiple rom and multiboot them

Hi guys

All of us know most of the stock android are hell and cuatom version for that same device is as good as heven.

But a custom rom always have a risk of damaging device.

What if you could install whole custom stuff on sd card and dual boot it with original.

Yes there is an app named boot manager in the market.

Just download and install it.

Download a custom rom for yourself. Open the app. Grant it root permissions. And head on to install rom. Tick all the three boxes of whipe data.wipe catch.wipe system and all. Select your rom and wait till it boot.

YOU MUST BE SINED INNNN IN THD NEW ROM TO USE THIS APP AND GO BACK TO STOCK ONE.

The app is 3$.

On xda piracy and havking is not allowed but if you want the app contack me at my hangouts

I can do muchbfor you

Peace

Managing Multiple Devices

Hi, I'm deploying 150 Android devices as handheld scanners for my staff here, I have logged each one in under the same Google Play account, but the first devices I deployed are asking to be re-verified with Google. Is there a way to increase the number of devices allowed under a single Google account? These devices are not linked to specific users, and do not have email addresses associated to them, so I cannot use a separate google account for each. Is there an upgrade to my account that is possible? Or is there a better way?




Thanks.
