It has only been hidden since Android 4.2. Back in Android 2.3, you just need to go to Settings - Applications - Development.

First, you need to be aware of two facts: Android uses more than one file system (think of "multiple drives/partitions" when comparing with your computer while sharing a common base, directory structures might differ between manufacturers So as starting points, I further recommend the file-system tag-wiki and the partition tag-wiki (you might also want to ...

At the moment a large number of popular website are dropping support for all SSL/TLS versions below TLS1.2 because of the known vulnerabilities in TLS1.1/TLS1.0 and older. Your device is very very old and does not support TLS1.2 therefore you can't connect to certain sites like https://wikipedia.org which requires TLS 1.2 according to the test of SSLLabs. ...

On Android Marshmallow, you can use the hidden System UI Tuner. Open the quick-setting panel, then press and hold the Settings' cog wheel until it starts spinning. You then get an additional settings entry in System > System UI Tuner > Status bar, where you can hide the alarm.

Use an app such as "Better battery stats". This app provides detailed information about all the services running. This is way better than the stock app for diagnostics. Additionally, a lot of the core services for the system are attributed as part of the "Android OS". There is a very particular bug in Samsung Galaxy S II devices relating to the TouchWiz ...

With Tasker you are able to achieve this. The Tasks can be defined as e.g. Wifi on and there are different trigers for those Tasks. Amoung many others, time can be a trigger.

ADB commands work without root. However the /data partition is only accessible by rooted users* and while /system can be read by anyone, it's a read-only partition and root is needed to remount it as writable. *There's one exception. The/data/local folder is accessible by non-root users too. This folder is primarily used for temporary like when you install ...

As eldarerathis already pointed out in his comment on your question: If the app is already installed, and the certificate matches, you will be prompted whether you want to replace it. If the certificates differ, there's a conflict: The app cannot be updated due to the mismatch, and it cannot be installed along as the package name is already in use (apps use ...

This is the icon that symbolises that the Verizon Network Extender is in use - could it be possible that the restaurant you visit has had one installed/set up? Source

The Kindle Fire will function as it normally would, but you cannot use the Video on Demand service while you are rooted. The Amazon Appstore functions fine even if you're rooted. You can revert to the "original functionality" with the "Unroot" button provided by SuperOneClick. Nobody knows this but Amazon. Honeycomb was not open-sourced when the Fire was ...

No, you would need an application like "Where's My Droid" installed on the device and know the phone number for the device. If you sold the device, the new owner probably did a factory reset on the device so your information is no longer associated to the device. In the future, before you sell your device, you should go in and do a factory reset so you ...

As I did not find any suitable solutions I decided to write my own widget. It's available on Google Play: https://play.google.com/store/apps/details?id=eu.siebeck.sipswitch I also made the source code available: https://github.com/robert7k/sipswitch

Update to Maps 6.9.0 (released 2012-06-27) or later if you not already have done so. Google added the feature one you wanted: What's in this version: * Save maps for use offline Besides this: Cached tiles for Google Maps are saved to the SD card. To also answer your exact question (for users that cannot upgrade): Use Android's provided 'move to ...

It's to alert you that the screen's about to turn off. It's more useful when your timeout is longer than 30 seconds, certainly. I would assume you'd need a custom kernel or at least to root and edit some config files in order to prevent this, I don't believe there's anything in Settings for it.

It looks like I may have found the problem. The latest update from AT&T (4.5.141.MB860.ATT.en.US) which they pushed a few weeks ago appears to not handle a "Forever" DHCP lease properly or my router does not properly handle a DHCP lease renewal when configured for "Forever". One does have to wonder why the phone was renewing a lease which had no ...

If you're using su to get root privileges when you shell in (which you've indicated you are) then that means you're not root on the shell by default. adb pull fails with that error message because it doesn't have permission to index the directory and pull the contents. You should be able to restart adb on your device with adb root first: adb root adb pull /...

This sounds exactly like this, down to ping working but not the browser. His eventual solution is quoted below: Stupid question, but are you editing the file on the handset or just pushing the file that you posted here? The one you posted is in dos format, so it has extra linefeed characters at the end of the line that could confuse a linux system. ...

I am assuming you have had your Droid 2 for a while; and have installed a lot of applications on it. I also assume that it is out-of-warranty. Performing a factory reset will remove all your apps and data - and without apps to run, yes your system will feel faster. However, as you add more apps over time, it will slow down again. Some apps like to run in ...

In short: GPS works without an active connection, it's completely passive. GPS has however an addon feature called A-GPS (assisted GPS) which speeds up the startup (time to first fix) considerably. It basically warms up the receiver with GPS status data such as time, coarse location and most of all GPS satellite orbit location data (ephemeris data download)....

Basic Concepts You are confusing two different concepts: "GPS" and "Navigation", that are used for two distinct scenarios on your device. GPS is used to pin-point your location in the globe. Navigation is used to plan and track your movements from point A to point B. While Navigation may depend on 3G or Wi-Fi to access the internet and retrieve maps and ...

I'd recommend Llama as you've wished for a free app. Further more this is a location based profile. This can not only do what you have said but also do what you want based on your location.

There are many "*2SD" methods, and they generally involve root access. My personal favorite is Link2SD. It uses symlinks, which take up (practically) no space. The actual program, data, libraries, etc are stored on a second partition on your SD card. This comes with the downside of actually having to create two partitions on your SD card (meaning it will ...

If you can connect using adb (usb debugging), you can simply use the command "reboot". If you're rooted and have a terminal emulator installed, "su reboot" will do the same thing. The reboot command will also accept arguments of "recovery" or "bootloader", which will reboot you into the recovery or bootloader respectively.

I am an Android Application developer. I had a requirement to make phone verification. In that case we had to make a telephony call to our server. But we could't achieve that as Android system does not allow us to make a phone call without users interaction. The best we can do is populate the phone number in the default dialer app. In any case user has to ...

There are no Android versions that support the 802.11 ad-hoc mode (unfortunately). To have ad-hoc working on an Android you need to root your phone. This however does not fix the basic issue that the Android java API does not allow you to programatically control the wifi interface in ad-hoc mode - to do that you need to resort to native code which is not ...

Sounds like the contents of your SD Card have not been scanned since taking the photos. Try the SDrescan app from Market. This should help in such situations. Alternatively, you can manually un-mount the SD Card (via Menu -> Settings -> Storage -> Unmount SD Card) and re-mount it again. This should trigger the media scanner to refresh the card's ...

Sometimes the culprit is much easier to solve: If accessing secured websites (https:) via the browser fails as well, make sure your date/time settings are correct -- otherwise certificates will fail. Best explained using an example: Say, today the date is May 28th 2013 -- but your device's date/time is set to January 1st 2010. Now you visit a secure website,...
