View 17 Replies View RelatedI was wondering what exactly SuperSU permission means. Does it means that if I grant a App SuperSU permission both at the install stage and later via the superSU rooted app, the app then have free hand to do anything on the device.I did a bit of research and ir does seem to be yhe case, wouldn't this be very dangerous to grant this permission to some less well know apps (ie not titanium backup calibre).
Although there is a separate permission for Internet access. Would an app with superSU be able to give itself stealth internet access and thus able to steal sensitive data over the net, or would I still be safe as long as the app dont ask for explicit internet permission.

View 7 Replies View RelatedIve read a few comments around different forums stating the droid x has ipddr2 running in dual channel but can't find any concrete evidence of it. Ive also read posts from people saying that the fascinate does not run in dual channel but is still ipddr2. What exactly does this mean and is there any truth to it? I was thinking if its similar to how pc memory works it could be why the x is getting higher benchmarks or is this all nonsense?
View 3 Replies View RelatedI am getting ready for a backpacking trip and taking my Droid along. As of now, I seem to be out of luck as to find a charger that will properly charge my phone when away from the normal means of charging. Has anyone used any portable batteries with their Droid? Right now, I have an APC Universal Battery 10WH and it doesn't charge my Droid at all. I am looking at the Just Mobile Gum Pro 4400mAh.
I have found that the Droids are very picky about where they get their charges from. I have a wall to usb and a car usb converter that doesn't work with mine or 3 other Moto Droids but will work with any other device that will charge via USB (iPod, GPS, other phones, etc.) Also, I have seen that the Minty Boost will charge the Droid, but their kits are backordered right now.
What does the "?" by my battery icon mean?

Sometimes when I send a message to someone I get a little envelope with a blue arrow on it. When it sends to the person, it's a green arrow, and when it doesn't send, it's a "text message not sent"
I don't think the message is received when the blue arrow appears.
I've written an application which involves a lot of simultaneous connections to different servers. I've noticed some big stability issues with this as sometimes the program crashes totally (not just ANR, but a segfault type thing). What's the recommended number of maximum simultaneous connections for speed and stability?

View 5 Replies View RelatedFor the buzzer round, I was thinking of writing 2 app for android (we have a few handsets), one for the quiz master and the other for the contestants.The contestants will be connected to the quiz master through bluetooth.After reading the question, the quiz-master clicks a button in his/her app, the button in the contestant apps will be enabled for X seconds. As soon as a contestant clicks his/her button, the quiz master's app will flash the name of that contestant.Is it even possible to have multiple connections and accept concurrent (or multiplexed) messages from them in bluetooth (something similar to select() in unix/c)?If possible, where should I look for any examples? What kind of problems will I face trying to develop this (I know reliability is an issue here) and how to avoid them?
View 2 Replies View RelatedI'm hoping someone could help me out with intermittent connections I'm getting using code with HttpsURLConnection.
The code I'm using is below:
CODE:...............
The connection works the first time everytime when I use it to pull a json file. However, when I use the connection again to send a command, it always fails the first time. It then typically works if I send the
command quickly ( within 5 seconds), but fails if I wait a while. I don't think its a SSL issue because it connects the first time correctly, but I could be wrong here. I also tried many different
variations such as adding:

However, I had no luck. Any help would be greatly appreciated.

View 1 Replies View RelatedI have some code that uses a network connection. I create a connection by calling openConnection() on a URL object. Is there any documentation that explains how this process works? Which access point is being used? When that access point becomes invalid, will it automatically switch to another accespoint? etc. I would like to use only WiFi access points and otherwise fail even tho 3G or GPRS could be available, is that possible?
View 7 Replies View RelatedI am working on developing an application that requires me to establish multiple client-server based connections. Connection can be of two types where the Android device can be a server or a client. I can have up to 6 - 8 connections. Once the connections are set-up they need to be running in the background and are not typically affected by UI actions.Since each connection can be blocking, I am wondering what is a good away to design this app. Should I have two services for handling the server and client connections? Each service could have a "connection manager" that can spawn new threads when necessary. Or does creating two services even help? I presume spawning new processed would not be good as they will be expensive. Is this correct? I would appreciate any suggestions. Also, if this use case is not typical please let me know if you need more information to make any recommendation.
View 2 Replies View Relatedmay be asking a bit much here but I have faith in the community so it's worth trying. I'm making a game and I'm trying to pick the connection type to use for communicating between a Java mobile client and a Java server backend.Socket programing in Java is easy - there's a lovely tutorial on the subject and two way communication is trivial.Trouble is that on a mobile client (Android) it's not guaranteed that the cellular network will let you make TCP connections. That makes me think using an HTTP connection is the way to go. HTTP connections are request based but I need a way to push notifications from the server to the client. It seems the solution to this problem is to use 'long polling' I have read a bit about it but have yet to see a simple example for what I'm trying to achieve.Again I might be asking a lot but this seems like a fairly common problem, is there a library or framework I can import / use to wrap a Http connection and provide a two way long standing connection (That reconnects automatically etc). I read a bit about cometD but it doesn't seem to have a Java library that I can just pick up.The communication I need is not heavy, not constant two way streams of data just occasional updates either way to keep the game going.

View 2 Replies View RelatedAre we able to establish both WiFi and 3G connections at the same time on Android 2.1? We are implementing a "make-before-break", so that WiFi can be switched to 3G before tearing the WiFi connection down. Please guide if you have come across this.

In addition, what if I walk away from home, wifi lost signal and switch to 3g? It should be safe to guess the connection is dropped. For my application, do I need to handle the reconnection or there is a auto fall back solution.
