I'm looking to build an app that will restart my device at a specified time, then open up a couple 3rd party apps in sequence and run their feature/s.
For example: I would like to automatically restart my phone at 5am. Then have it open an antivirus app of my choice and run the scan. Then close that app and open up another app and run it's cleaner function.
I have experience coding, but I'm just starting to take a peak into android app development. So, I was wondering if this is something feasible to do.
Any advice would be appreciated!
I am not sure about the starting phone at the desired time, but I am sure you can start applications on boot using "init". Linux systems support that, and android does as well. But it completely depends on your kernel.
Read here about init.d.
Check if your phone's kernel supports init.d. Check here if your phone doesn't have init.d support.
Check Here for running a script at boot. It is quite useful for custom scripts.
Check Here for running scripts/application the application at boot
Create a script according to your needs and I think you would be able to achieve what you are looking for. <- Custom Rules
I would have commented but apparently I can not since I am new here.
I hope I was of some help. Will look into the android starting part and get back to you.
Cheers.

i want to make an application or more like a tweak for android
i want to write some code that's gonna work on an android device and will do curtain actions based on an input from a Bluetooth device
this application needs to run in the background at all times (as if it was part of the device's operation system)
and be getting input every second
i need it to be able to bring up i custom keyboard i am gonna design and to set up a courser just like in a desktop which can be controlled by the application.
i read about something called a ROM and i dont know if thats what i am looking for.
i also know that the android operation system can be modified or replaced with another operation systems like the one called cyanogen .
i am a beginner and i have got some background in java
i tried creating an android app but i dont know how to make this thing work on the OS
i need someone to give me a very detailed explanation cause i know nothing about these stuff
It sound like your trying to make an App that takes Bluetooth input...
It doesn't sound like you need to edit the OS itself...
You need to set up the Android SDK to start development...
http://developer.android.com/sdk/installing/index.html
1. Download the SDK
2. Install the Eclipse Plugin
3. Write the code, and run it on the emulator or your connected device(make sure debugging is enabled under Setting->Applications->Developer)
Here's some info on getting started w/ Bluetooth...
http://developer.android.com/guide/topics/connectivity/bluetooth.html
Since you want this to run all the time, I would look into Android Services also...
http://developer.android.com/reference/android/app/Service.html
You may want to also take a look at the Sample Projects included w/ the SDK after you download the SDK and set up your IDE and Emulator(or phone)...
http://developer.android.com/tools/samples/index.html
Hope this helps clear some stuff up...
Okay here's the deal:
I want to download the full source of the MMS/SMS application that ships with Android phones. I want to be able to modify it, and add a little custom functionality to it.
I am developing using Eclipse, and I'm on Windows 7. I have noticed that there is now a Git for Windows, but I am pretty lost in it and not sure how to integrate everything with Eclipse.
Basically, I want to just get it to the point where I have all the source code visible in Eclipse and be able to see the app run JUST like the built-in texting/MMS app that is already on my phone. Then I'll know that I can modify it and proceed.
Any ideas?
Thanks!
There's a mirror of the SMS/MMS app on GitHub here. Just import that to Eclipse and customise away.
Unless you want to customize and use it only on your own phone (without publishing), this is not a good idea. This is because it uses classes that are hidden from the sdk. By default you won't even be able to build the apk via eclipse, but there is a way. The reason why this is a bad idea is that the hidden apis are not guaranteed to remain the same through different api-levels and your app can stop working with the next android update, and might also not work on previous api-levels. In-fact your app might not even work on selected phones running the same api-level.
Hy everyone, I'm Korean and a little short on using english so please try to understand if I say things not appropriate.
So, my status is that I have odroid-s.
What I'm trying to do for like month or more is that I want to make android to HelloWorld.
What I want to say is that, on the odroid-s, bootloader part, kernel part is the same but the framework part(which will be android), I'll remove all the android part and replace it with just HelloWorld program. The purpose of this HelloWorld program is to display HelloWorld on the screen.
What I think I discovered is that, as I 'vimdiff' bootlogs between normal bootlog and the one that I removed all the system partition part (which is android system partition part) is that android kernel's init goes on and executes console(/bin/sh), netd(bin/netd), ... and it enables adb and it completes his work.
So my conclusion is, I need to use Linux kernel that is non-modified and modify it for odroid-s, and use that kernel for my HelloWorld program!
What I want to ask is.... Am I doing it right?? T_T
My goal right now is to make HelloWorld come out from this odroid-s device...
Please somebody help me. If anybody don't understand what I wrote plz tell me, I'll fix it.
Thx for reading....
The modifications to the linux kernel are likely to be irrelevant to your goals, so you might as well leave them in place for simplicity.
Your biggest challenge is going to be output - where do you want to send it? If you had one of the devices that has (or can have with the right kernel config) a debug serial port, then it would be really easy to write something triggered by the init script (or even use 'echo' in the script) which outputs your message on that port.
But chances are you want to put something on the screen. This is going to be overwhelmingly more complicated, and perhaps device dependent. The way the android runtime does this for actual apps is going to be way more involved than you probably want to get into.
A more practical approach might be to look at how the boot animation is done. For starters you could just replace it with a static image that says "hello world". Once you can do that, the next step would probably be to find some character generator code. Finally you might want to implement scrolling and other terminal-like features.
As an alternative approach, there are builds of more traditional linuxes for some android devices - debian or ubuntu for example. These may include console implementations capable of displaying on the device screen.
As another idea, if you are flexible about how much of android you would be willing to leave on the device, you could build a version of the android terminal emulator example, modified to be a home screen replacement. You might be able to remove a lot of android components (eventually including the default home screen). Or on a secured device (ie, most consumer devices that haven't been rooted) you could just do the home screen replacement while leaving the actual system unmodified. It wouldn't be secure against users wanting to run other things, but generally the user would interact only with your code.
I am performing some experiments where I want to replay a previously captured packet trace from Android. So far I have written my own application to replay the trace and get then answer back from the server. Timing accuracy is not a big problem as long as is within reasonable bounds (e.g., some milliseconds).
However, I would prefer to use a tested tool like tcpreplay. Is there any project that have ported tcpreplay to Android? Given that libpcap is available, there should be something available, but I could not find anything.
Thanks for your help
I'm the author of tcpreplay, and I can't say I'm aware of an Android port. Never owned an Android device so can't say one is coming anytime soon.
I've got it running on my tab, you need to install GNUroot and Debian no root, they are both from the same developer... After get it, open GNUroot, check emulate new root, create rootfs and run the rootfs, after this "apt-get install tcpreplay". If you want to capture use TpacketCapture in the play store, you can also get Tpacketcapture Pro to use the capture in only one app.
If you are planning to hack games don't publish it, cause this vulnerability can be easily patched...
any question email me.
Is it possible to configure the Android OS to run only a single app?
Basically what I want to do is customize an Android device so that it boots up and runs one application only, and for that application to be switched to the front of the screen automatically. Also, when it gets closed, to be started up and switched to again. Any ideas?
Thanks,
-David
One method is to get the source of Android and write your own custom ROM of Android as Octavian wrote.
Another alternative would be to write a custom home app that, well, isn't really a home app (but replaces the default home app intent). See SlideScreen as an example of a non-traditional "home" app.
Yes it is possible. You have to fetch yourself the source codes for Android and basically create a custom ROM. After applying all desired modifications you bake your ROM and install it to your device.
Pretty much all you need to know about the source and the process of compiling the sources are located at Android Sources. You can view the source codes from your browser by following this link.
Hope it helps you a bit. Good luck.
