I have this requirement which i need to boot phone only with my android app, full screen. No OS GUI or navigation bar or anything.(Sorry if i'm using wrong terminologies here). I don't need others to be accessible to anything in OS or environment but the app. Is there any way to achieve this.
Note: I'm using android 4.2

Hello everyone,
Can anybody explain how dual boot works.
Whether android is booted on top of windows mobile as some upper layer or does it rely on hardware as it is native OS installed. Is there any difference between native android phone and android booted from windows mobile, except missing some functionality?
Thanks
Cheers!
when you use heret to boot android winmo is shut down, then android runs as the native os, this is nessesary as without android being flashed to the devices rom there would be no way to boot it obviously. in theory if android is made stable enough on a device it would be possible to make an android rom for that device
To add some additional information:
You are probably talking about the Gen Y dual boot software.
Gen Y dualboot is nothing more than an application that runs immediately after Windows is booted. So before you get to the dualboot, Windows is actually already booted.
Then, after pressing Android, Windows Mobile launches the Haret, by which Windows Mobile shuts down and the Android Kernel loads up.
So to have it in a schematic view:
-----------------------------------------------------Stay in Windows Mobile
Kernel WM --> WM booted --> DualBoot <
-----------------------------------------------------Launch Android Kernel --> Android booted

I don't take any credit I Googled everything. I do take credit of modifying some stuff in word. The idea came from here. I may have took some of his work. SO credit him and Pirateghost for the information about Android.
ADB → Android Debug Bridge (adb) is a versatile command line tool that lets you communicate with an emulator instance or connected Android-powered device..
Android →Unveiled on 5 November 2007, Android is a mobile operating system running on the Linux kernel developed by Google.
ASOP → Android Open Source Project
Apps2SD → Move applications from the internal NAND memory on the device to a removable SD Card.
Bloatware → Software bloat is a process whereby successive versions of apps include an increasing proportion of unnecessary features that are not used by end users, or generally use more system resources than necessary, while offering little or no benefit to its users. Like all the crap that comes from At&t
Brick → When used in reference to consumer electronics, "brick" describes a device that cannot function in any capacity (such as a device with damaged firmware). This usage derives from the fact that some electronic devices (and their detachable power supplies) are vaguely brick-shaped, and so those which do not function are useful only as actual bricks. The term can also be used as a verb. For example, "I bricked my phone when I tried to modify its firmware."[
Hard Brick → When your phone does not turn on at all. When you can’t get in to CWR/CWM Or Stock recovery. You are basically screwed.
Soft Brick → When your phone bootloops. When you can get into CWR/CWM. When You can use jigtag to get into download mode.
Busybox → BusyBox provides several stripped-down Unix tools in a single executable. It runs in a variety of POSIX environments such as Linux, Android, FreeBSD and others, such as proprietary kernels, although many of the tools it provides are designed to work with interfaces provided by the Linux kernel. It was specifically created for embedded operating systems with very limited resources. Platforms counterparts, but they are pretty close and useful nonetheless.
CWR OR CWM ClockworkMod Recovery →A custom recovery for Android phones and tablets that allows you to perform several advanced recovery, restoration, installation and maintenance operations on your Android device that aren’t possible with the stock recovery.
DEODEX → Apk files have respective odexes that devs use to supposedly save space. Deodexing means you convert it back to a .dex file and put it back inside the apk. This allows you to easily replace file (not having to worry about odexes), but the main point was to deodex services.jar so that you can change all text to different colors (such as the clock color to white) and to deodex services.jar, you need to deodex everything.
Flashing → The process of applying a firmware image (or ROM) to a device. It generally entails a very specific order of steps. Failing to complete any one of these steps properly may result in bricking the device.
Firmware → is a term often used to denote the fixed, usually rather small, programs and/or data structures that internally control various electronic devices. Programs stored in the ROM, EPROM, or flash memory that usually control various internal electronic devices (Hard Drives, Keyboards, Displays, etc). Firmware is typically 'fixed' software that is not updated in consumer devices, however it is often updated (or 'flashed') by advanced users to fix bugs or add features to the device. Flashing firmware designed for one device onto a different device, or not following a specific procedure while flashing will often render the device unusable.
Kernel → is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components
Radio → The cellular radio on the device which needs control software called firmware to control it.
ROM → Read Only Memory. In the context of an Android device, ROM is the internal flash memory where the core operating system resides. It can also refer to a specific version firmware that can be applied to a device through a process usually referred to as flashing. An improperly flashed ROM can often brick the device, rendering it unusable.
Superuser→ A program, which gives unlimited access privileges to perform any or all operations on the operating system.
ODIN → Odin is the Samsung software used to update Samsung phones. It does not work with any other devices other than official Samsung phones.
OTA or FOTA → (F)OTA stands for (Firmware) Over The Air and is the process by which required updates and enhancements to your phone's basic operating system can be sent to you through the cellular network. The Galaxy S II software update will be sent via FOTA and is available through Samsung Kies mini.0
ODEX → In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.
SDK → Software Development Kit.
Logcat → A debugging tool built into Android devices that displays system logs as they occur. See Logcat.
NANDroid → A set of tools that will enable anyone who has root on their Android device to make FULL system backups, in case something goes wrong or you want to try out that new experimental ROM/theme. NANDroid will backup (and restore) /system, /data, /cache, and /boot partitions.
Recovery Mode → A special environment that you can boot into for troubleshooting and upgrading purposes.
Kang → The process of creating a code based of someone else's code or reapplying code that someone else created into your own code (e.g. git cherry-pick)
Rooting → is a process that allows users of mobile phones and other devices running the Android operating system to attain privileged control (known as "root access") within Android's Linux subsystem with the goal of overcoming limitations that carriers and manufacturers put on some devices.
Hey , Guys this Thread Is Specially Made for Noobs. With All Info For Android.
So , Let's Directly go to Topic
Firstly What Is Android?

What is Root?
★In Simple Word Rooting Means gives Read-Write[RW] permission on System Dictionary.★
Rooting*is the Android*equivalent of jailbreaking, a means of unlocking the operating system so you can install unapproved (by Google) apps, update the OS, replace the firmware, overclock (or underclock) the processor, customize just about anything, and so on.

______________________________
What is Recovery?
A combination of key presses (or instructions from a*command line) will boot your phone to recovery, where you can find tools to help repair (recover) your installation as well as install*official OS updates.

What is Bootloader?
•Every Android phone has a bootloader that instructs the operating system kernel to boot normally. But you need to understand one thing here that as Android OS is an open source OS and is available on a variety of different hardware, every manufacturer has their own version of bootloader specific for the hardware present in it’s environment.

1. Bootloop - Bootloop means your phone doesn't but up right, it's just starting and starting and nothing happens, or it's starting and shutting down and starting again. It just means your phone makes a loop while booting.
2. Brick - Brick means your phone can't boot up and you can only recover it with for example flash the stock rom. But there are different bricks for example soft bricks (for example bootloops) and hard bricks (for example doing and over the air=ota update when bootloader is unlocked). There are some other bricks and examples as well.
There Are Two Types of Bricks
1.Soft Brick - you can still turn your phone on but it doesnt really start (bootloop i think is a kind of soft brick. )
this kind of brick can be fixed through softwares like flashtool.
2. Hard Brick - you can't turn your phone on and it doesnt really start, you don't get any response from it.

What is Custom Rom?
A*custom ROM replaces your device's Android operating system — normally stored in read-only memory — with a new version of the Android operating system.
Some Famous Custom Roms Are

Hello Everyone
So I was wondering (I've searched the site,with no luck finding what I need)
I would like to customize and build the Android OS for my mobile phone.
My Physical Test Device Info:
- Samsung Galaxy J1 Ace, SM-J111F
- Running Android 5.1.1 (I've upgrade the rom from 4.x.x to 5.1.1)
Customizations would include:
- Password Protect The Recovery Menu (Like BitLocker's Password Prompt)
- Password Protect The OTA (Over The Air) Download Menu (Like BitLocker's Password Prompt)
- Password Protect The ABD Flashing (Enter Password Through The ABD Command Prompt, Before A User Could do any updates or data uploads/download to the Device)
Please could you let me know what files might need changing also any info relating to any tutorial which I can follow.
Kinda Starting from scratch (I have no android OS development experience, except for a few apk apps from Unity3D)
I'm a software engineer, I've worked with Embedded Systems Running C and C++. a few webs apps and some backend C# systems.
Thank you so much for the help and support in Advance!
Good day gentlemen, am wondering if I could use risky apps (might contain viruses) with DSU? In other word just like a Virtual Machine?
Thanks
you can use android emulator on android
