• How to enter safe mode on your tablet. How to enable safe mode on Android? Detailed instructions

    If you followed the previous tutorial to create a "Hello World" Android project, which included a set of source files allowing you to run the application right away.

    How you run your application depends on two things: do you have real Android device and whether you are using Eclipse. This tutorial will show you how to install and run your application on a real device and on an Android emulator, both using Eclipse or command line tools.

    Before running your application, you should be aware of several directories and files in an Android project:

    The AndroidManifest.xml manifest file describes the main characteristics of the application and defines each of its components. You will learn about the various advertisements in this file as you progress through the tutorials. One of the most important elements what your manifest should include is element. It states that your application is compatible with different versions Android, using the android:minSdkVersion and android:targetSdkVersion attributes. For your first application, it should look like this: ...

    You should always set android:targetSdkVersion as high as possible and test the application on the appropriate platform version. To receive additional information, read. src/ The directory for your application's main source files. By default, it includes an Activity class that is launched when your application is launched using the application icon. res/ Contains several subdirectories that contain . Here are just a few of them:

    Drawable-hdpi/ Directory for drawable objects (for example, raster images), which are intended for high density(hdpi) screens. Other drawable directories contain sets designed for other screen densities. layout/ Directory for files that define user interface your application. values/ A directory for various other XML files that contain a collection of resources such as strings and color definitions.

    When you build and run Android application by default, the default Activity class created starts and loads a layout file that says "Hello World". The result is nothing exciting, but it's important that you understand how to run applications before you start developing.

    Run on a real device

    If you have a real Android device, here's how you can install and run the app:

    1. Connect your smartphone to your computer using USB cable. If you are developing on Windows, you may need to install the appropriate USB driver for your device. For help installing drivers, see OEM USB Drivers.
    2. Turn on USB Debugging on your device.
      • On most devices Android control 3.2 or older, you can find the option in Settings > Applications > Development.
      • On Android 4.0 and later, this is in Settings > For Developers.

        Note: On Android 4.2 and later, For developers hidden by default. To make it available, go to Settings > About phone and press Build number seven times. Return to the previous screen to find For developers.

    Android Studio :

    Open one of your project files and click Run app on the toolbar. Or press the key combination Shift+F10.

    A window will open to select the connected real device or emulator. Android Studio installs the application on the selected device and launches it.

    To launch the application from Eclipse:

    Eclipse installs the application on the connected device and launches it.

    Or to run the application from the command line:

    1. On your device, find MyFirstActivity and open it.

    Here's how to build and run an Android application on your device! To get started with development, read.

    Run on emulator

    Are you using Android Studio, Eclipse or command line To run your application on the emulator you must first create virtual device Android (AVD from English Android virtual device). AVD is the device configuration for Android emulator, which allows you to simulate various devices.

    To create an AVD:

    To run an application from Eclipse:

    Eclipse installs the application on the AVD and runs it.

    Or run the application from the command line:

    1. Go to the root directory of your Android project and run: ant debug
    2. Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then do: adb install bin/MyFirstApp-debug.apk
    3. In the emulator, find MyFirstActivity and open it.

    Here's how to build and run an Android application on an emulator! To start developing, read the next lesson.

    Games for mobile devices are developing by leaps and bounds. Just five years ago, users had primitive projects like Candy Crush Saga, Talking Tom, and self-made quizzes. After a couple of years, games appeared with more exciting gameplay, graphics and even plot. These include:

    • Asphalt 8;
    • Dead Trigger 2;
    • Modern series.

    Even then, questions began to arise about how to run Android games on a PC. But even here, development has not stopped, and the market now offers full games like X-COM: Enemy Within and GTA San Andreas, desktop analogues MOBA– Mobile Legends or Vainglory and real ports, for example, Hearthstone: Heroes of Warcraft and others. Such abundance cannot but please active users of mobile devices, but it causes envy among many PC gamers, especially considering the fact that most games are for tablets and smartphones distributed free of charge, monetized only through in-game purchases. Therefore, solutions for playing on a computer in Android were not long in coming. They existed before, but now they are tailored for specific purposes - getting a full gaming experience from mobile games on the computer.

    Android games

    First of all, it’s worth saying that we are talking exclusively about how to run games on Android, because iOS devices They do not provide the ability to install games from external sources at all.

    Apk files which are installation packages, you can’t just run it on Windows systems. This is due to completely different libraries and frameworks used in different OSes. Therefore, the option that is used is emulators.

    The concept of an emulator

    They represent themselves virtual mobile devices , running inside your desktop system. " Computer in a computer" Of course, to launch them, and subsequently to operate the games, you will need enough advanced hardware, therefore, if you are hoping to play mobile games because of their low demands, you will have to discard this idea. Or play something really primitive that doesn’t consume a lot of computer resources.

    There are already quite a lot of paid and free emulators. They offer different capabilities and interact differently with your device in terms of performance. If your goal is just to try the game, choose something simpler and faster. If you want to play constantly, then you should aim wisely. AND don't forget about performance. To the resources consumed by the program itself, you need to add those that the game will need.

    The last caveat is that many emulators are launched using virtualization technologies, which differs depending on the manufacturer of your PC chip. To enable it or make sure that it is active, you need to go to BIOS.

    Perhaps, the most popular solution running mobile games on Windows is . This is not full emulator and it is designed specifically for games. It is written entirely in Russian and has a very nice interface. This is not virtual smartphone on your screen, but a full-fledged PC program that skillfully hides its roots. And the process of working with it is ideally designed specifically for players.

    To use BlueStacks, download the program installation file and run it. After installation, open the application and you will see the start window. Here, in the process, personal recommendations will be formed and everything will be located installed games, but now you should use the search. Download the game you want from Google Play and run it. It will open in a new tab, allowing you to quickly and easily navigate throughout the program and switch between games. Of course, you can always launch the desired apk if it is not in the store. On the left side there is an extremely convenient toolbar for taking screenshots, changing orientation, and so on.

    From additional featuresstreaming of a running game process directly to Twitch and syncs with your Android device.

    The next one, this time a full-fledged one, not just a game option - . This is already a real emulator, but it looks just as high quality and is extremely pleasant to use. Plus, it is also as close as possible to the experience from regular smartphone or tablet. IN in this case is an add-on for Android called CyanogenMod and the Nova Launcher.

    To the user in full access settings for the emulator itself are provided, where you can specify the desired resolution, performance level and other details; and device settings for choosing a language, etc.

    Of course, here, in addition to the standard Google Play, you can use apk to install applications, take screenshots and run several programs at the same time.

    – also a real emulator, but it comes even closer to the standard form Android interface, however, only version 4.0. All the same features of other programs mentioned before are relevant for this solution. Google Play, apk, screenshots and full support hardware component of your PC.

    Finally, it wouldn’t hurt to consider an option that would be suitable not only for gaming, but also, for example, for development. Genymotion is an emulator that interacts with integrated development environments on Windows and thus allows you to test software or games in almost real conditions. You can choose it if, in addition to games, you are a developer of your own projects.

    Additionally worth noting is Leapdroid. This is a solution, the quality and performance of which was noted by many real users on the network, but having appeared recently, it just as suddenly ceased to be supported by developers. Of course, it won't be difficult to find working distributions, but be extremely careful with malicious files.

    There are also from Chinese developers, but the official website of the program is on at the moment does not work, so the program cannot be fully recommended. However, it gives excellent performance, and full power uses your PC. Theoretically, any, even the most challenging games will start up and work 100%. Mistakes are possible, but this is a fair price.

    Also considered a quick and convenient solution for Android launcher programs, but it looks quite sparse and offers a minimum of functions, so it is mentioned only for information.

    Conclusion

    Running mobile applications on a PC is now really in demand, given the quality of their execution. The only thing you need to remember is to compare the power of your device with the requirements of the emulator and the program being launched. If your needs are minimal, choose a program with the simplest requirements and start playing. Each of the solutions mentioned in the review is worthy of becoming your desktop solution. It is worth highlighting only Genymotion, which has a wider range of capabilities. And once again remind you about the possibility of infecting your device when downloading installation files not from the official developer sites.

    Our article is dedicated to brief overview two emulators of Android applications for PC. You will learn how to install and run mobile programs on PC, as well as how to set up controls for Android games on the keyboard.

    Many users go beyond the Android OS and want to install mobile applications and games on your computer. In this case, emulators come to their aid.

    Android application emulators- This special utilities, which replicate the interface of an Android device and allow you to run mobile programs or games on a computer (Windows, MacOS).

    I use two emulators on my computer - and Droid4x. I use exactly two, since not all applications run successfully on one, but run without problems on the other. We can say that they insure each other.

    Bluestacks 2- most popular Android emulator in the world that runs the lion's share of programs from Play Market, and also has own base adapted games and applications.

    The developers are constantly working to improve it, and in the new part they added a direct stream to Twitch through the function BlueStacks TV.

    How to install BlueStacks 2 on PC:

    1. Download the utility from the official resource -. I give a link directly to the Russian version.
    2. The installation is largely automatic. You simply start the download, confirm your selection and click next.
    3. After installation, you need to go through a little setup - by authorizing your account information from Google Play Market. This is required for direct download from the store.
    4. Next, enter the main Menu. On the left you will see a search icon - click on it and search for the game you need directly from the Play Market.
    5. All further downloading and installation repeat similar steps on the Android device.

    Attention! Some nuances:

    • as you will use free version- you will sometimes be offered advertising installations, you should follow them;
    • The system requirements are not small, and you need to allocate up to 10 GB of hard drive space.

    Droid4x- it's relatively young, but promising project, which is made at a decent level and runs most Android games.

    There are no particular difficulties in installation and configuration:

    1. Download the program installation from the official source - droid4x.com.
    2. The installation wizard will do everything for you, you just need to confirm your choice.
    3. We also enter our data in the connected Play Market for direct download.
    4. After launching, in the main menu, click on the Play Market icon, search for and download the application we need.

    Probably the only negative- lack of Russian language, but this will not complicate experienced users at all.

    Setting up controls on BlueStacks 2 and Droid4x

    Many people face the problem of setting up controls in emulators, because many games use multi-touch, which makes mouse control inconvenient. In this case, everything is very simple and the settings for Bluestacks and Droid4x are similar.

    Surely everything experienced users Those working on the Windows operating system know that a safe operating mode for the OS is provided to troubleshoot and solve any problems. But not everyone is aware that mobile gadgets can also be loaded in a similar design shell.

    Let's try to figure out how to turn on the phone in safe mode (Android), and what steps need to be taken to do this. We will consider ordinary devices - tablets and smartphones running on official (stock) firmware. If you upgraded your gadget with amateur (custom) firmware, then the steps described below may not respond correctly or may not work at all.

    Why is this mode needed?

    Before enabling safe mode on Android, let’s decide why it might be needed on this platform at all. As you know, the Android operating system is distinguished by its, so to speak, democracy, while other shells try to protect their “inner world” as much as possible from possible errors novice operator. That is, the user has access to almost all software corners of the gadget. By using third party software you can easily change not only appearance operating system, but also her behavior, and beyond recognition. And as often happens, you have to pay for such beauty.

    If, after all your interventions, the platform began to slow down, freeze, and generally stopped functioning normally, then you begin to ask the question: “How to enable safe mode on Android to eliminate these lags?”

    The fact is that this mode can be called “clean”, that is, when it starts, only the main system services are connected, where you can trace the history installed applications and make some adjustments, and then reboot to normal operating state.

    So, how to enable safe mode on Android? In total, there are two main ways that will allow you to enter a “clean” system.

    First way

    You need to press and hold the gadget's power button until the reboot pop-up menu appears. Then you need to press and hold your finger on the “Disable device” item. After 5-10 seconds, a dialog box should appear that will warn you about entering the safe operating mode after clicking on the “OK” button. Some versions of Android (usually on tablets and phablets) can immediately reboot without any additional windows. Keep this in mind before you enable safe mode on your Android tablet.

    After clicking on the “OK” button, your gadget should reboot and start only on basic system services. Moreover, the process may take some time, a little longer than during a normal download.

    Second way

    Turn off your mobile gadget, as you usually do. Wait a few seconds and then press and hold the power button. After your phone brand or brand appears on the screen, hold the volume rocker in the “+” (increase) position.

    After this, the icon “ Safe Mode» ( Safe Mode), and the device will begin loading the platform on the main system files. In some versions of the OS, it is not necessary to hold the power button, just wait for the logo to appear on the screen and hold the volume rocker. Also keep this point in mind before turning on safe mode on Android.

    How to disable Safe mode?

    As a rule, this mode is disabled after the gadget is rebooted, and there is no need to perform any additional steps. If the phone continues to start in safe mode, it means the platform does not want to work correctly with installed third-party applications or the system is completely damaged.

    The only way out in this case is to reset all settings to factory settings (“Settings” -> “System reset”). Separately, it is worth noting that all information will be deleted, so worry about the transfer in advance phone book and other important data.

    Not everyone knows that, like in Windows OS, there is a safe mode on Android devices. What is it and why is it needed, we will now figure it out.

    Safe mode on Android is a mode that, when launched, only system systems work. pre-installed applications. Anything you downloaded and installed yourself will not function in this mode.

    What is Safe Mode for?

    For example, we installed a bunch of third party applications and one fine day, the smartphone or tablet began to glitch, freeze, slow down and produce various errors. We start the smartphone in safe mode and remove all the “garbage” that could cause unstable work devices. If this does not help, then we can make a diagnosis: a malfunction in the Android OS itself.

    That is, safe mode is an excellent tool for diagnosing your device. Also, thanks to it, you can find out how much faster and better a “naked” Android works, not cluttered with various widgets, applications and other software products.

    All manipulations will be performed with a device running Android OS 5.0.2

    Click on it and confirm the reboot by clicking “ok”.


    Another window will appear in which the program will ask for root rights. Click "allow".

    The device will reboot and turn on in safe mode.

    Method three

    Another similar application is simply called "Reboot". It is similar in functionality to the previous version. You can download it

    Instructions:
    1. Download, install and launch the application.

    2. After launch, immediately grant the program root rights by clicking the “allow” button.


    3. In the main menu, select the “Safe Mode” item and click on it.


    4. Confirm the reboot by clicking “Yes, reboot now.”


    5. After rebooting we will enter safe mode.

    Method four

    This time we will use a program called Easy Reboot, which you can download
    Turning off Safe Mode

    To exit Safe Mode, simply reboot your device. After switching on, it should work in standard mode. If any problems arise and after rebooting the smartphone is still working in safe mode, remove the battery, wait a minute and insert it back. This helps in almost 100% of cases.

    If this does not help, then try rebooting your smartphone using a combination of the power button and volume + or volume -.

    Conclusion

    So we figured out what Safe Mode is and what it is intended for. Now, if your device is unstable, you will know how to diagnose the system yourself.
