[Q] Can an android phone run without screen? - Android Q&A, Help & Troubleshooting

Hello,
This would be my first post here ! so please bear with me
I want to know or confirm from the advance users for the following facts:
1. Can an android mobile be used even after removing the led socket from the mother board.
2. Can android mobile start directly when the power source is connected.
My project:
I want to build a GPS device from the mobile hardware . Specially the phone with AGPS support !
Can you please tell what older models are cheap and available or there hardware is available. I have made an app that runs in background on start of the mobile and sends coordinates to the server.
Hardware
- Motherboard
- Gps antenna
- SIM CARD

What hardware platform do you plan to use?
What is your end goal/intended use?
Will it interface with something else via USB or Bluetooth?

[New Project] Help needed on getting TMC running on X10 Navigation

Hi Ppl.,
I'm starting a new project with this thread.
Goal is to get TMC running within Navigation Software on X10.
As we all know from the specs and my determining over here, that there is no FM Chip assembled to the X10.
But our User drobec208 had the Idea to make use of an external bluetooth / TMC device.
The Idea is to use the "FM9BT-C", made by GNS GmbH with "usually TMCable" navigation software. (Nice side affect: FM9BT-C also brings a 5V, 1A USB Charger ).
I ordered one FM9BT-C and received it yesterday.
As I make use of Sygic mobile maps for Android, I knew from the .ini files, that TMC is just deactivated after stock installation of Sygic.
Within the folder: "\sdcard\Drive\Android\" you can find the .ini files too.
But now, I'm a little stuck.
I can't even connect FM9BT-C to X10.
Pairing works fine, but the my phone shows: "Paired but not connected".
I also can't connect both devices.
I guess, it's the same issue, like I had with my Bluetooth keyboard:
Android 1.6 is simply not capable for HID Devices.
So I guess its same with the TMC Device.
The TMC Device needs to be set up with a COM Port.
But atm I don't even get so far.
So guys, whats your advice?
Any Devs around, that can help out?
Do I have to wait for 2.1 this month?
Is Android not TMC capable at all?
Kind regards,
McK
O.k., as far as I could determine myself, a Bluetooth COM Port is needed for sure.
But how can I set it up in Android?
Is is that impossible with 1.6?
if it's connected via BT I'm affraid the problem is limited Bluetooth profiles support on 1.6. The USB on FM9BT-C is just for charging?
O.k., I feared something like that.
As the Update to 2.1 will come in a few Weeks, we will see more, after it was released.
Du you know something about the profiles in 2.1?
Japp, the USB connector is for charging only.
not much, just google I'm waiting for 2.x just because of BT profiles and my SE MBW-150 support via OpenWatch http://beta.smartmadsoft.com/
http://developer.android.com/sdk/android-2.0-highlights.html#PlatformTechnologies
http://www.google.com/support/forum...n&fid=40c6f9447eac44e600047f171034e819&hltp=2
otherwise I'm affraid we have to wait for 2.2
http://developer.android.com/sdk/android-2.2-highlights.html#PlatformTechnologies
I've also recently found this Thread in a German Forum:
http://www.android-hilfe.de/439320-post42.html
Roughly, fast and only the important thing translated: Wit Android 2.1 for X10, the Bluetooth Stack will be updated to Bluetooth V 2.1, which introduces:
- secure simple pairing
- GAP Generic Access Profile
- GOEP Generic Object Exchange Profile
- OPP Object Push Profile
- PBAP Phonebook Access Profile
- SPP Serial Port Profile
So, we have to wait a little more....
@MBW-150: OMG? S///E X10 isn't supporting a S///E Bluetooth Watch... *[email protected]///E*
Uhm, bad news.
I still get "paired but not connected".
Even after updating to 2.1.
I guess the connection has to be initiated by software (like on the bluetooth keyboards).
Does anybody know the name or so of the bluetooth com port?
I'd try to connect through Sygic Mobile Maps.
hi, I'm not glad to hear that.
what happens if you try to find TMC device from within the Sygic?
P.S: My MBW-150 finaly works with X10

Unfortunately: Nothing...
My last hope is to set the bluetooth comport manually within Sygic.
With a little chance, it will activate the connection if it knows the way...
But I don't know the port
Is there an app, to list the ports or so?
maybe http://code.google.com/p/android-serialport-api/ ?
Uhm... I have no idea how to use that App

[Q] How to setup wi-fi direct?

Hi all,
Just wondering how to setup wi-fi direct? I've gone into the menu and enabled it, hit scan, but it doesn't find either of my 2 laptops.
Do the laptops have to be wi-fi direct certified as well or is there some sort of configuration I have to do to make them available to the phone?

i wish i knew mate, i'm pestering people to find out myself. nobody seems interested. i was linked this video, but the guy is hard to understand and it doesn't work in the way he demonstrates it on my laptop. maybe his is wifi direct certified - thats not really clear ether. have a look anyway, maybe you can figure something out.

wi-wfi direkt is disabled on newer devices by samsung.......... because they have problems with licenses
I use wifi direct to send files from my phone to my friend's phone (he also has the Galaxy S II). Works perfectly and is really fast.

So I guess both devices must be wi-fi direct certified, because my phone doesn't pickup my laptop at all (which is about 3 years old).
Intel Wifi dashboard
there is a programm called intel wifi dashboard , this program enables wifi direct on laptop and then your laptop will be discovered by GSII
WIFI direct is like a private network between your laptop and your GS2 or just 2 GS2 that enables you to transfer files up to 1 Gb in size in just 2 or 3 mins ( i tried it myself by sending a 730 mb wmv file ) without the need of setting up a wireless network
and obviously it's much more faster and effiecent than bluetooth
Has anyone managed to transfer files between Galaxy S2, Galaxy S3 and PC using Intel Dashboard?
I can get my Samsung SMART TV to detect my Android Phone

Okay, so I just rooted my phone and flashed a new ROM and it has Wifi-Direct option on it which basically, you just tick to enable and cannot configure. Since my Samsung SMART TV was wifi-Direct certified, I opened the Wifi-Direct Menu and it just detected my phone. It told me that I could either connect by pushing the Wifi-Direct Button on my Device (PBS Way) or by entering the TV-generated PIN on my Device( PIN Way). But I cannot see a "Enter the PIN" Notification pop up on my Android Device. Let me try a Third-Party App and lets see how it goes.

[Q] HELP!!! using 3g dongle with tablet to make call

Hi everyone,
I would like to know if there is an android app or any other methods or fixes or any ways to be able to make calls like a phone from a 3g unlocked dongle on a tablet pc that supports usb 3g dongles like there is software for pc's such as mobile partner? If there isnt can anyone one of you advanced android programmers create such an app or fix? The 3g dongle already supports call making and sms sending features. I have scoured the net for a solution but to no avail. I think this one is for the advanced xda developers. Thanks in advance and take good care.
Come on people!!! Somone must have an idea on this?
Bump!
Still no luck?

It has been more than two years since this post. Still no luck with such an app that allows calling through a usb dongle?
sry i know that threat is old.. but are some one know is there any way to use 3g dongle to use it to calling on my android device
lol to this day there is no software or fixes for 3g/4g dongles except ONLY ONE....... heres a thought though! there are new mobile sim calling devices being manufactured these days where you insert the mobile sim card into the device which has a telephone and a keypad and you can make calls, perhaps its because of this reason there are no softwares, SOME SORT OF BLACKLISTING. to allow sales.
the android app you need is called PPP Widget. theres an old version and a version 2 try them both.

Adding WiFi to the LG G Watch

Is there any way to equip the LG G Watch with WiFi, like the Samsung Gear Live. I have read that the G Watch lacks WiFi because it does not have a WiFi antenna. Can a WiFi antenna be added to the watch? Or, what about connecting the G Watch to a WiFi chip via Bluetooth? Would any of these work? Thanks!
i dont think so, wifi has to be built in on the rom, a simple bluetooth wifi wont work, but modifying hardware may work but its more difficult.

@Jaocagomez Thanks for your help. How would I add WiFi into the rom programmatically? Also, what would the hardware modifications be like? Also, couldn't I create an app/client that uses a WiFi chip attached by bluetooth to update notifications? Thanks!
You would need to add the drivers built specifically for the Android kernel. The ROM would need to be built with WiFi support enabled in Android (which currently I believe is impossible as you cannot procure the source code to Android Wear atm). A Bluetooth WiFi adapter would not work because Android wouldn't know how to deal with it at all, The reason that the GWR was able to enable WiFi was because support was already built into Android as it was part of their hardware base. It was simply missing the drivers for the kernel.

Also the Wear app on the phone wouldn't allow the watch to use WiFi, as the model doesn't have it as a standard.

It probably would actually, I've been given the option to use Cloud Sync my gWatch connected.

I saw it there also, but someone said it just broke the connection with the watch and required to do a Factory reset. Read it sometime last year, when WiFi for Wear rolled out.
The watch contains no WiFi radio so obviously it cannot use wifi. The only wireless technology it uses is Bluetooth 4.1 LE.

Enable Mobile Data while connected via Wifi (Xiaomi / Android Auto Wireless Problem)

Hi there,
i would like to use Android Auto Wireless which is slowely rolled out at the moment.
First only Google Pixel phones could do it, now Samsung phones are certified too.
In theory it could work with every Pie (Android 9) device.
I bought a new Kenwood Headunit for my car and it works after enabling it in the developer options - BUT - without internet connection.
The phone automatically connects to the headunit's wifi and that's it. No internet available. Of course the headunit doesn't provide internet and wifi is just used for the connection.
My phone is a Xiaomi Mi Max 3 with MIUI11 (ROOTED) and Android 9.
Google Play Services: current beta (19.4.20)
Headunit Kenwood DMX8019DAB
How can i force the phone to use mobile data when connected to the headunits wifi?
Thanks
...

Hi. I go tomorrow bought that unit. I dissapointing that android auto use usb. I have samsung S8+ + pie9

I have the same issue with my oneplus 6t when connected wirelessly to my Pioneer AVH-W4400NEX. My mobile data/LTE disconnects and wireless android auto becomes unusable. Needs help here.
I use a OP7TPro now and maybe this helps because I needed to change this setting to make it work:
Settings - WiFi - wifi settings - automatically swap to mobile data (or something like that, it's german on my phone)
I have the Android 10. Yup basically that it the solution. Go to wifi preferences and enable "auto switch to mobile data". Thanks.
Unfortunately this doesn't work on Xiaomi phones. One of the reasons I switched.
