Whether you want to prevent your child from accessing Facebook or are simply sick of the advertisements that litter webpages, a custom hosts file can come in handy. The easiest way to edit the hosts file on your device is to use the Android Debug Bridge, so go ahead and set it up.
Once the command prompt opens run the following command to see what devices are attached to your PC. Now comes the fun part: adding the host entries. Really, you can do anything you want for example, you can use your host file to block ads from appearing on websites instead of using an app like AdBlocker, or in our case we can just block a website like FaceBook by redirecting it to localhost — you will have to search around to get the exact domains to block.

Some apps might generate data that ultimately belongs to the user, and so, would prefer to store the data perhaps documents or media in a public place that the user can access at anytime, using other apps. Other apps might want to store data, but do not want this data to be read by other apps or even the user. You should use this to save primitive data in key-value pairs.
An app can have multiple Shared Preferences files.
Ideally, you will want to use Shared preferences to store application preferences. There are lots of situations where you might want to persist data but Shared Preferences is too limiting. You may want to persist Java objects, or images. Or your data logically needs to be persisted using the familiar filesystem hierarchy.
The Internal Storage data storage method is specifically for those situations where you need to store data to the device filesystem, but you do not want any other app even the user to read this data.
Data stored using the Internal Storage method is completely private to your application, and are deleted from the device when your app is uninstalled. Conversely, there are other instances where you might want the user to view the files and data saved by your app, if they wish. However, beginning with Android 4. Beginning with Android 7. This way, your app can, for example, request access to either the pictures directory only, or the documents directory.
This is referred to as scoped directory access. For more information about requesting scoped directory access, check out this Android developer tutorial. Finally, Android provides support for apps to use SQLite databases for data storage.

Kevin Guan Editing your hosts file the file that maps hostnames to IP addresses, for those of you who were previously unawareis useful for everything from controlling access to websites and network traffic to just mapping addresses to names. Whether you're a developer looking to make some DNS tweaks or just a concerned parent looking to block certain sites from their kids, hosts file modifications have got you covered.
You can go about this process in two ways, depending on whether or not your Android device of choosing is rooted. While the process isn't exactly rocket science on a non-rooted device either, it's definitely more straightforward on devices that have been rooted. If you don't already have ADB, you can grab it from Google's developer resource page. Connect your device to your computer via USB make sure you've already enabled USB debugging in the developer settings. Run the command adb devices to ensure your device is connected, and that ADB is reading and interacting with your device appropriately.
Now, simply navigate to the directory which you copied the hosts file to, and edit away! Remember, once you're done you need to push the file back to your device.
This method is nowhere near as lengthy and should take you less than 5 minutes, even if you're a slow tapper. Open your file manager of choice we recommend a file manager like Solid Exploreras it allows for easy adjustments and modifications to read and write permissions. Select "Group" under write permissions.
You should now have sufficient permissions to modify and overwrite the hosts file. Reboot your device and navigate to the hosts file again using your file manager. Select it, press "More" and tap the "Open" option. You will need a text editor with Superuser access, like TurboEditor. A whole host of interesting things excuse the pun. Everything from speeding up lookups for specific servers with static IPs by adding a custom host to restricting certain servers from sending info to and from your phone — hosts file modifications have it all.
How to modify the hosts file on your Android device

Ok, that's all good but what can I actually do by modifying my hosts file? Log in or Sign up.Last week, when working on the new release of the eat foody Android app, I run into a significant issue.
For some reason, my requests to our staging API were incomplete or somehow broken after updating to the newest version of our request library. After some rather clueless digging I knew I needed to run the broken requests against a debuggable server environment. This allows me to compare how the request leaves the Android app and arrives at the server.
However, this rather obvious choice does not work, since localhost is the Android emulator or the device itself. The next two sections will describe solutions for making requests to your localhost server. The bad news first: this solution only work with the emulator and not with your actual devices.
So start up your emulator since it could take a while until it is ready. Start your server at localhost and attach the debugger. Run the Android app on the emulator and cause the requests you want to debug. This should enable you to catch the incoming request on the localhost server. In my case, this quickly resolved my issue. Obviously, the use of this method is not limited to debugging.
If you are on the train and have no Internet connection, you can use this approach to develop your app anyway. A different approach is necessary when you want to avoid using the emulator. However, this solution requires you to be on the same Wi-Fi network.
Once again, all requests should go against the localhost server running on your computer.

Can someone tell me what that is? And can I have them both run off of 1 URL. Instead of having one for the emulator and actual device. You need to use the IP address of the computer, on whatever network that the computer and the device share. You cannot access localhost on one machine from another machine, by definition.
Of course, you also need to figure whatever it is that is running on that computer to listen to more than its own localhost. Is there a way I can use a single IP Instead of using Not really. Moreover, neither of the values that you are thinking of are the right ones for a release build of your app, in all likelihood. There, you will need to use the domain name or, in a pinch, IP address of some publicly-visible server that everyone's devices can reach. You have to use the ip address of your computer for a real device.
