The easy way is to go to your WiFi Settings, and hit Menu > Advanced. It'll show up there, or you can set it to a static IP if you want. The cool way is to dial *#*#4636#*#* to open the Testing menu. Then click WiFi information, then WiFi Status.

Usually apps require internet access for ads, analytical data, or for sending bug reports/stack traces back to the developer. Other reasons might include using Google's licensing servers to validate legitimate copies of apps with Android market purchases (Google's licensing servers use the CHECK_LICENSE permission). Similarly, some developers produce their ...

Using only your Android: Kaspersky's Parental Control software does exactly as the title says. Mind you, it's still in beta, but I did install it and tried it out, and it seems to do it's job of blocking websites as well as applications. By the way, Kaspersky's not the only app out on the store that you can use, but I chose it due to its reputation. It's ...

YES. You will use it as a regular phone, but will be disconnected from the networks (Facebook, Twitter, IMs, Sync, etc) YES. You can access your calendar offline. And yes, you can sync when Wi-Fi is available. Yes, you just disable data traffic.

Android comes with ifconfig, install Terminal Emulator and type "ifconfig eth0", or use "netcfg" to list all available devices. You need root to use ifconfig though.

It is saved in /data/misc/wifi/wpa_supplicant.conf file. You can open it with any text editor. If you have Terminal Emulator you can also do this: cat /data/misc/wifi/wpa_supplicant.conf

Android has "partial" support for IPv6, which basically means there's some code for it but it doesn't really work yet. Check this Google thread for more info.

Poor connection may mean that: there is either a weak signal from your wifi partner device. there is much noise from other systems using the same frequency. Both mean that many data-packets are lost and have to be retransmitted so your overall throughput goes down. You can compare this with: somebody is speaking not loud enough many people are ...

This app makes the Android devices be able to connect to Internet directly via ...

The following works for a while, but only for the browser. When you plug in your phone via usb and choose Internet pass-through, you should get a new RNDIS device (usb0 or usb1). For ubuntu, edit /etc/network/interfaces and add the following lines: iface usb0 inet dhcp iface usb1 inet dhcp This will assign an IP automatically when the device is added. If ...

This functionality is built into android so there's no need for an external tool/application. In settings: Wireless and networks -> Mobile Networks -> Data Enabled Disable this and you're all set.

While @k3b is right in what a poor Internet connection means that's not what's causing the error message to appear. If you actually have connection issues you don't get an error message (pretty counter-intuitive) It appears that since upgrading to ics people have a problem with this. Theoretically there should be a setting to switch this off under: ...

This problem has been plaguing me ever since I upgraded my Sony Ericcson Experia Pro ("iyokan") from Cyanogenmod 7.2 (Android 2.3.7) to 9.0 (Android 4.0.3) -- until today when I did some more detailed investigation. It's pretty clearly a defect related to the DHCP client. When it manifests, the device fails to obtain an IP address from any access point, ...

Yes all this is possible but you'll have to root the tablet and whether or not that is possible will depend on the tablet. Here's the answer to each request: Yes, you have to edit the hosts file for which you'll have to root the device. Yes, any browser (I recommend Dolphin HD) will let you set the home page, so just set this to the page you want it to ...

Updating this question to say that as of Android 4.0, IPv6 is fairly well supported. There are still no visual indicators that it is running/working, but devices pick up IPv6 addresses and try to use them by default.

On a typical Linux system the cache is cleared by running /etc/init.d/nscd restart, but at least my ROM doesn't use nscd to cache DNS. You can check if yours does, but I doubt it. I've seen suggestions that clearing the brower cache would clear DNS cache too, but one sure way is to do a hard reboot (shutdown, remove battery for 30s, reattach battery and ...

Depends entirely on how many contacts you have, how often they change, how often you set it to sync, etc. Paying for data as you go is generally a bad idea with an Android phone, they use a lot. You should be able to shut off 3G though (probably dependent on the phone) and just use WiFi. Although, it might be more difficult to prevent it from using 2G ...

Seeing that you have 2.2, the easiest solution would be to go to Settings -> Wireless & networks -> Tethering & portable hotspots. There you have an option to enable usb tethering (exactly what you asked for) or, even better try out Portable Wi-fi hotspot. That way you will be able to connect to the internet without connecting the phone via usb, and ...

I think not. A least, not efficiently. If you want to do that, you need servers, big servers, so you need a big company to run thoses big servers. So I would be very surprised if that big company doesn't advertise for its product, as Opera did.

Well, if you had your 3G off, then they can't access that, I suggest if you didn't override it, use APNdroid from the market to do so and it also features a good widget. Anyways, applications can't override your WiFi settings, if it's off, then they can't turn it on, but if you left your 3G on without any overriding application, like APNdroid, then they ...

Firefox Mobile supports HTTP proxies, so whilst it's a different rendering engine you should at least be able to get a feel for how your UI performs on a small touchscreen. Here's how to get to the secret config section - http://support.mozilla.com/en-US/questions/758279 The default browser includes proxy support in Gingerbread (although that doesn't help ...

Addresses are cached for 600 seconds (10 minutes) by default. Failed lookups are cached for 10 seconds. From everything I've seen, there's nothing built in to flush the cache. This is apparently a reported bug in Android because of the way it stores DNS cache. Clearing the browser cache doesn't touch the DNS, the "hard reset" clears it because it simply ...

Apps use ad cache to show you ads when both Wi-Fi and mobile network are disabled. You can use something like DroidWall to prevent an app accessing the Internet. But this requires a rooted phone.

There is the turbo feature in Opera Mobile -- the same UI as Mini with a more normal renderer. The compression is less effective, though.

There's currently no way to set a system-wide policy for this. Some apps do support doing things on WiFi only, however. Here's some info on the apps you mentioned: You can go into the browser settings and uncheck Load Images. GMail does not load images unless you view a message and click a button to display them. I believe the Touiteur Twitter client ...

The only way to do this in Android is to do a hard reboot. The necessary command-line tools are not normally available, however in my tests a hard reboot has always done the trick for me (Galaxy Nexus, and HTC Desire, various ROMs). This is a pain, but it is quicker than the 10min cache timeout.

A made this small bash to automate all. Just plug your phone in charging mode to your computer and run this bash. #!/bin/bash /opt/android-sdk-update-manager/platform-tools/adb shell 'echo 6 > /sys/devices/platform/msm_hsusb/usb_function_switch' sleep 1 /opt/android-sdk-update-manager/platform-tools/adb shell ifconfig usb0 192.168.99.5 netmask ...

No. This completely disables all data access. Only calls/messages can be used. EDIT: You might try looking into something called JuiceDefender. The free version will disable your data access when your screen turns off. Good for both battery saving and data-usage saving!

XDA developer capslock66 has developed a reverse tethering tool which is the simplest yet (and hopefully in future too). Only requirement is a rooted phone. You can download it from here- Android reverse tethering via usb It comes as a zip file with all the adb files and dependencies. Once you open the application, it will do all the settings on your phone ...
