Android :: 2.2 - Portable Hot Spot - WifiManager Class

Nov 9, 2010

I'm looking at how Android supports wifi portable hot spot functionality with a view to writing simple home screen widget that allows people to turn the phone's wifi hotspot on and off without digging into the device settings.

There was nothing obvious at developer.android.com so I dug through my copy of the Android source code and found that the WifiManager class (android.net.wifi.WifiManager) provides the basics to allow the state to be queried. So as well as 'getWifiState()' there is 'getWifiApState()' and a matching set of state constants.

However, in my bang-up-to-date Eclipse IDE, this class has none of the Ap methods or constants. Can anyone shed any light on this?

Samsung EPIC 4G :: Press Hot Spot App Without Hot Spot Add On To Your Plan?

Sep 27, 2010

I see a Sprint Hotspot app on the Epic. What happens if you press it? Does it auto-activate the hotspot, or does it check to see if you have the add-on plan before it can be used?

Android :: WifiManager.calculateSignalLevel - RSSI 5

May 20, 2010

I am trying to use the Wifimanager to calculate the Signal Level of the access points found during a scan.

I am using the following method:

WifiManager.calculateSignalLevel(int, int)

But it appears to always return the same int no matter what the RSSI level is.

Here is my code:.............

The logging outputs 1 for all the test cases for calculateQoS(int).

Am I missing something simple here? Why is the SignalLevel always 1?

Android :: Using On PND - Portable Navigation Device

Apr 21, 2010

I'm looking for a PND on which i can install android.

For example: http://www.medion.com/de/electronics/prod/MEDION%C2%AE+GoPal%C2%AE+P4440+EU/30010109A1?category=navigation_28&recId=&wt_mc=de.intern.m-shop.pro-pla.on-ma&wt_cc1=m-shop_topseller_navigation-2-links&wt_cc2=30010109A1&wt_cw=30.2.8&utm_source=Internetseite-intern&utm_medium=Kachel&utm_content=navigation_2-links&utm_campaign=Kategoriekachel-Hotspots&utm_term=30010109A1

I would like to install Android - not on a mobile phone, like it's commonly down - but on a navigation device. In doing so I want to completely remove the old operating system and replace it with Android. Is this even possible, provided the hardware matches Android's requirements, or are there other criteria to be aware of ?

Android :: Portable JDBC Vs SQLite

Aug 11, 2010

I am using SQLite in a project used by an android application. Currently I am using the SQLite implementation provided in android.database.sqlite.

I want to make a desktop application which uses the same codebase. So I need to separate all the shared behaviour into a separate portable project/jar.

My problem is I'm currently making heavy use of android.database.sqlite. If possible I do not want to re-write every database access call to be compatible with JDBC or whatever I will have to use without using the android provided SQLite.

To solve this problem with minimal impact on the existing code. I intent to write a SQLite interface (compatible with android.database.sqlite) which the shared code will use... on android it will be implemented trivially by android.database.sqlite, and on the desktop it will be implemented by somehow mutilating SQLite through JDBC to match android.database.sqlite.

This is proving difficult as I often supply Object[] arrays to be bound to prepared statements which JDBC requires strict typing, and I am not familiar with JDBC at all.

Is there any other way to use SQLite in Java which is similar to android.database.sqlite, or any other approaches which may save me the effort (and inevitable debugging) associated with re-writing many database access points?

Disclamer: I have never until now tried using JDBC.

Simplified question: What is the best way to use SQLite in java? JDBC, other?

Android :: Communicating Between Receiver Class And An Activity Class

Jul 14, 2010

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

str = s;

Android :: Running Mapreduce On Portable Devices

I have heard of people who have successfully run mapreduce on a google nexus one. There is no more info on the performance of running a full clustered mapreduce on android.

I would really like to run mapreduce on my phone on a relatively small amount of data non clustered mode, is it really worth it to use the hadoop completely ? is there a stripped version available anywhere? any alternatives?

Android :: In Java, What Does A Reference To Class.class Do?

Jul 20, 2010

I'm building a small Android application, but this is more of a Java question than an android question. Looking through the tutorials there are lines that look like: startService(new Intent(this, MyService.class));

What exactly does the "MyService.class" field represent? Is that just a reference to the class for a template?

Android :: Lanyard Loops - Important To Portable Gadgets

Jan 20, 2010

It bugs me that some phones are omitting the lanyard loops. Look at the Nexus One that doesn't have it: http://gizmodo.com/5451349/look-at-this-broken-nexus-one

iPhone didn't have it.

Pretty lame that some phones now are designed without this feature.

General :: Turn Old Android Phone Into Portable Gaming Device?

Dec 18, 2011

So I upgraded from my Droid X to an Galaxy Nexus. I have a perfectly good - freshly sbf'd Droid X that none of my family wants or needs so I'm thinking it could be a decent portable gaming device for my boys when we travel. Just toss it in the Otterbox and let em have at it.

I always see the iPhone folks talk about giving their kids their old iPhones to use as an iTouch and I'm thinking I'd like to do that with my DX if it's feasible.

I'm just not sure it would work as well. Can I simply create a new gmail acct to register it at when going thru the setup we we can download some free games from the Market? What about the phone activation process - can I just skip that?

Android :: Wi-Fi Hot Spot

Jul 8, 2010

I've been trying to read up on the Droid X's Wifi Hot Spot, but I can't find much about it other than little bits and pieces.From what it sounds like is that the Droid X will act as a wireless router for up to 5 devices. So I can fire it up, and my laptop can connect to it to get internet access on my laptop.I've read that up to 2GB/mo data will cost around $20/month through Verizon. Is this on top of the monthly data plan that I already pay for?I've also read that there are some phones you can root and once rooted, you can get unlimited wifi hot spot.I'm sure it will be awhile before the Droid X gets rooted, but until that happens, I'd like to know what my options are.

Android :: WiFi Hot Spot On 2.2?

Aug 31, 2010

if I read this correctly, with 2.2 Android OS we have capability to turn our phones into WiFi hotspot, but it come at cost from Verizon. I already pay $45 for corporate unlimited data usage, paying anything extra on top of that for the times when I use my phone as hot spot just seems ridicules.
Isn't there any apps or ways to avoid the extra gridy charge from Verizon for the WiFi hotspot usage?
