Android :: Auto Enable Wlan Only When Available Access Point In Range?
Nov 21, 2010
I have just recently moved from Nokia E75 to HTC Desire, and there are lots of stuff on the E75 that I will never miss... But, there are a couple of things I am missing very much, tho. One thing was a very clever feature that saved a lot of battery... On my HTC Desire I have to leave wlan enabled at all time for the phone to utilize wireless at all, and I can see that it's consuming approx 20% of the battery power - even if no apps or widgets are accessing internet.
But on the Nokia E75 it's very different... The wlan is switched off by default, so whenever an application on the E75 needs a data connection (internet), it will quickly enable wlan and check to see if there are any networks nearby it can access, and then disable it again if it doesn't find any. (If no wlan access point is detected, it will go online using the mobile data connection automatically instead)

I have successfully programmed insertion & deletion of an Access Point in database but I need to find out how to update an access point. I'm using db.update() but its not producing any result. I am using the following code to update an access point:
ContentValues updateFields = new ContentValues();
ContentResolver resolver = getContentResolver();
updateFields.put("name:", "AIRTEL");
updateFields.put("apn_addr", 11023);
resolver.update(TABLE_APN_URI,updateFields,"_id=?",new String[] {Long.toString(2)});
While updating I'm not getting any error as well.

I was wondering is it possible to get a notification of when a new configured network is added to the Wifi Manager in Android? I know you can get the current list of configured networks.
http://developer.android.com/intl/de/reference/android/net/wifi/WifiM...
But is it possible to get notification of when a new one is added? I don't see anything in the Wifi Manager that would be helpful. How this could be achieved?

Does Android provide a notification of being in vicinity of a new Wifi Network? Whether the device is configured to connect to that wifi network depends on whether the device has the wifi configuration set for that particular wifi network, but is it possible to get notification whenever entering any new wifi network?
I saw the WifiManager class but the states inside the class do not seem to achieve what I am trying to do. Any ideas?

How does the "Allow automatic updating" works? I notice that my apps have "A manual update is required." when I try to enable it. Is it anything I need to do in my codes to enable this to work? Or is it depending on the permissions required by the apps?

Is there a way to force all my requests to be made through my APN and not through wifi, without having to disable WiFi? I want to know if it is possible for my application to use exclusively the network access point. I'm already able to set the default network APN and to use it but for this I have to disable the Wifi first.

I am using ralink WiFi driver in android, I am able to connect to the access-point using the Wireless Settings provided in the Android, But once I connect to the network and restart the WiFi. I have to reconnect manually by providing the authentication key. WiFi Manager is not remembering the last access point used. I am using the Settings application provided by the android.

I have two WiFi access points in my house, due to thick walls. When I turn on my phone it searches and connects to the first access point it finds, which is not necessarily the one with the strongest signal. e.g. I have one access point on channel 10 (lounge) and another on channel 1 (bedroom). When I'm in the lounge it always connects to the A/P in the bedroom, unless I actively "forget" that network, even though the signal strength of the one in the bedroom is VERY weak. Is there a way to force it to pick the strongest A/P?

I have a question regarding WiFi setup on my Android. When I'm at home, I want to use manual IP settings for my WiFi (instead of relying on DHCP). However, when I'm out using other WiFi (a coffee shop, or at school) I obviously need DHCP. How do I set manual IP settings on a per-wifi-hotspot basis?

I have an application in which I need to connect to an access point with a specific name. Therefor I start a scan (WifiManager.startScan()) and listen to BroadCastEvents of type SCAN_RESULTS_AVAILABLE_ACTION and NETWORK_STATE_CHANGED_ACTION. When the scan results are available, I check if my AP is found and if so I connect to it.
When I'm connected to the AP, I receive a NETWORK_STATE_CHANGED_ACTION and there I open a SocketConnection to my serverSocket. The problem I'm having is that on the moment that I'm connected to the AP, the DHCP request is not yet finished. This causes the opening of the socketConnection to throw a "SocketException: Network unreachable". A few moments later I see in the logcat logging: WifiStateTracker - DhcpHandler: DHCP request succeeded. If I try to connect after this message, all goes fine. is there an event that I can listen to that informs me that the DHCP request is done? Now I try to create a connection and while an error occurs I retry. This is however very dangerous for hanging (if e.g the dhcp fails, the loop will never stop...)

I have a text field and when I use the IME (the default one for Nexus One) it doesn't display the auto-suggest line on top of the soft keyboard. Ironically there are posts here on how to prevent the auto-suggest, but in my case it's the revert, it doesn't show up and it's not clear why, Code...

I want to control the system settings "auto brightness", setting it ON or OFF.I'm able to control the brightness level but only if AUTO is OFF. From what I read until now there is a SCREEN_BRIGHTNESS_MODE in Settings.System but only for API level 8 or higher and also not recommended to mess wit it. But currently my phone has Android 2.1 (API 7) and there are widgets that can control this setting (enable/disable auto brightness and set the level). How is this done?

I think that's the only negative thing that's happened since updating to 2.2, the Vodafone access point (APN) has been wiped and for some reason has defaulted to an ASDA one!

I want to develop an application that disable the Background Data (new feature in Android 1.5) and Auto Sync and then enable GPRS/EDGE connection and vice versa.
I figured out how to enable/disable GPRS/EDGE by changing the APN settings. (weird solution. However; Android developers couldn't think a user may want to disable GPRS/EDGE) But, I couldn't find a way to enable/disable Auto Sync and Background data.
I investigated the Android code and as I understood, the Sync operation is an intend. So, I wanted to reach with putExtra to the intend and trigger the enabling/disabling. But; I couldn't find the correct keyword.

Does anyone knows if the wifi networks for android phones are based on Access Point Names (APN) ? I ask because in my android application I plan to overwrite some fields in all APN's to disable cellular network, but I still want to have available the wifi for the user.

I've been emailing the dev of Toggle Data Widget because I could not get it to work on my droid reading through the comments I was not the only one. He is telling me to look in my settings under wireless & networks and tell him what I have for APN's. Well the thing is I don't even have anything in there! Does some body know where to find what he's talking about? I emailed him telling him I couldn't find it anywhere and he seems baffled as well.

I know there was another thread on this topic that linked to the XDA forum but that thread is more about loading a specific kernel to enable AP Tether. I like Hydra's new kernels and you can do the same thing with them as well. I attempted to install the newest version of Wireless Tether from the market but it did not allow AP mode. So I found it's necessary, as verified elsewhere, to install the (wireless_tether_2_0_5-pre3.apk) version.
Once I did this and added the bin file, it worked great. WPA2 security is also included in this version. So to make it easy, I just created a zip that's already called Android.tether and has the required .apk and .bin already inside for AP Tether. This is not supported with the stock kernel, check to see if your kernel of choice supports it if you are in question. I can for sure verify the Hydra OCUV 1.113 ghz v0.8 kernels.

I am unable to connect to my Droid. When I start the tether, I don't receive any errors (although I haven't checked the log), but when I look for the Droids access point, it's not shown on the list. I have access control enabled and it hasn't notified me that a device is trying to connect. I followed and have only done the following to root and to install wireless tether to the phone:
