Android :: How To Make Device Boot When Power Is Plugged In?
Nov 12, 2010
I need to use this for a Samsung Tablet.Usually if the device is switched-off and the USB cable is being connected the display will wake up for some seconds showing an animated battery.Instead I want to let it boot.I suspect this is close to the metal. Where do I have to make a modification?In the kernel, in the Android platform, or is this hidden in some proprietary code of the manufacturer?

.My phone isnt detected by ADB during its boot. After bootup it shows up in the list of attached devices. Im trying to port MIUI v4 to my device so I need a logcat during the boot because it just hangs at the bootanimation but ADB doesnt see my device during boot. If I force a logcat, the log is emply.
I have tried several ROMs and on both Windows and Ubuntu and still no result.

Rooted Aria/Liberty won't turn on if it's plugged in (wall charger or USB). The orange charging light is on and the screen is lit but black. The menu buttons do not turn on. I have to remove the battery after unplugging it for it to turn on.
The phone is rooted and the problem is consistent no matter what ROM I use. I believe it is a problem with the bootloader, but I'm not very advanced with these things.
I rooted the phone with Unrevoked and whenever I boot into recovery mode it says "Revolutionary CWM v4.0.1.4."I know it's minor, but it is my mother's phone and every time I'm on the phone with her she complains about it.

I'd like to keep the screen on whenever one of my Activities are running and the phone is plugged in to a power source. I know that Wakelocks are tricky, so I'm looking for an example or some documentation on how to accomplish this specific goal.

Does Android keep an internal log that is similar or identical to the log you can view with adb logcat via a Terminal window? It's difficult when my app crashes while I test it out in the field...
Any help would be great! I'm hoping Android keeps a log and there's some way I can access it. Oh, I do have root on my test device.

As per the title, I have a client who wants this done to their generic chinese/yarvik tablet. It uses the Allwinner A10 cpu afaik. Due to my very limited experience in building kernels(where I believe the "option" to enable/disable this is)/roms + the lack of sources for the tablet(just getting into fastboot took a while).

I'm thinking about an Android app (with possibly an accompanying physical device), and i'm trying to figure out whether this is something that's feasible.
1) Let's say I plug my Android to my PC. Would it be possible for an app installed on the PC to communicate with an app running in the cell phone? I just need a very simplistic data exchange, it can even be one-way (just data pushed from the cell phone to the listening app on the PC, whenever the cell phone wants, I don't need any data sent from PC to phone).
When I plug it in, the phone gives me 4 options (charge, disk drive, HTC sync, tethering), which makes me think this is not doable, but still worth the shot.
2) Would it be possible for an app on the PC to talk to an app on the phone through any other way? (Wi-fi, bluetooth, etc). I'm guessing no on wi-fi since neither party has the other's IP (and I want this to kinda just work, not having to input IPs manually all the time).
3) If I make a device that's plugged to the little USB port at the bottom of the phone (and let's say this is a magical device that can do anything, I don't quite care about those details as long as it's doable). Can I have an Android app talk to that device?
4) Any other ideas to make the phone talk to a "device" that I make, or to an app in the PC are more than welcome. Going "through the web" could be an option (although there'd have to be a central server that I own as a middle man, I believe). But i'd prefer if the communication was direct between the two devices.

My phone( HTC Explorer /Pico A310) wont completely boot unless power cable is plugged. Yesterday, my phone just restarted when I was doing nothing. Then it goes till white screen where HTC logo is displayed(before boot animation) and restarts. It goes on repeatedly.
If I remove my battery and reinsert it after some time, phone starts automatically(without pressing power button) and goes to boot loop. I can enter into HBOOT by holding volume down key but factory reset, recovery etc wont work.
When I insert my power cable, It starts as it should, everything is fine. If I remove it while phone is on, it just restarts and whole process repeats..
My phone is not rooted, its still in stock rom GB 2.3.3. Its still S-ON.
I tried factory reset by power cable plugged in, reset was successful but nothing worked.. problem still there..

As I was nervously trying to install a custom rom, i wipe everything off my device ( HTC Desire X ds ), as per required by the instruction. But before in could install the rom, the device shut itself off. Now I can't even start it on bootloader, it just simply display a black blank after a short htc logo appears. Then after a while it vibrate 7 times in a row.

Has anyone else noticed that the Desire seems to power off VERY VERY slowly, or is it just me? Literally, and with no exaggeration, I hit the power button on the phone to power it down at 10:38am, and as of 10:56am the thing is STILL trying to power off.
I don't turn the phone off very often, but every now and then it's worth it, but it's taking far too long and I keep having to pull the battery. Anyone got any thoughts?
I'm assuming theres an app that is causing all the bother, but I can't think what. Anyone know of any apps that have this sort of problem? If noone knows, I'm going to have to factory-reset the phone, and I really don't want to have to set it all up again.

I want to develop a peripheral device to connect to an android phone via USB OTG. The OTG specs [1] says: "A Targeted Host shall provide sufficient power to each peripheral on its TPL in at least one supported configuration".
Where do I find those TPL ("Targeted Peripheral List") lists? I searched at Sony Ericsson (because I have a Xperia Mini) and Samsung (as a different manufacturer) but with no luck. Is this an android related list?
On github I found a code fragement [2] from DooMLoRD. It mentions a OTG whitelist. But it seems to be something like a skeleton.
I do this research because I want to use the peripheral device in high power mode with about 300 mA. I thought I could compare the TPL with devices that also need 300 mA.

Using Android, is it possible to automatically make your phone initiate a screen gesture (like a swipe across the screen) whenever you hit the power button, then proceed to turn off the phone? I know it's a very weird question, but I have my reasons.
I imagine it's possible with some type of app like Tasker, but I don't know if Tasker can initiate screen movements that imitate a finger moving across the screen in a point and direction of your choice.

I have a rooted Nexus s on 4.1.2
I am wondering if there is an app that can power off my device when battery drops to a certain level. Tasker's shutdown task not seems working for me.

I have written a class which extends the Service class of android and would like to launch the service during device boot-up. From the service I would like to receive the intents such as boot completed and screen off and on. Currently I am using a BroadcastReceiver to get the boot completed intent and then on starting a service to receive screen on and off intents. But I would like to remove either the broadcast receiver or the service. Any inputs.

I have registered a Receiver component for ON_BOOT_COMPLETED broadcast, in my application. The receiver does just prints a line in its onReceive() callback. However, when I boot the emulator(by executing Run as->Android application command from Eclipse) and unlock the screen on start up, I get an ANR dialog displayed in my Application. Following are the exceptions logged:

If I take the SIM out, the device will boot and give me access to contents, (obviously, phone is off).BUT if SIM is in, I cannot get past the pin input screen, and this is exactly what I want to do.
I want to be able to give the device to my son to i.e. read a pdf, but I do not want him to be making / answering calls on my SIM.
Sure, I can take it out, but do not want to if I do not have to. (I might lose it too!)
In other words, if no pin is entered, one must be able to use all but the phone on the device.
After all, the lock is for the SIM, not the device!

Very often I find myself needing to reset or get around someone's Windows Password, the easiest way of course is with one of many available linux boot cd's that'll edit the windows system hive. However most of the time I'm not carrying this around, I have a USB stick that can be used but I noticed earlier that while my Nexus One was plugged into the USB port on boot it is detected by my bios.
So the question is - Can the android USB interface act as a boot device? If so I assume it'd need a different partition since it's already got an OS?
(Also while I have your attention: 1) Did they ever fix the +1 area code problems with contacts?, 2) Why don't half my contacts show up in Send MMS dialogue (and others)?, 3) How do I tell if I have an SLCD or AMOLED screen cos sometimes the screen looks really crappy (dithering or off colour banding) AND FINALLY 4) can you set notification sounds differently depending on time of day (ie; I don't want a new gmail alert to wake me up at 2am.

So last night I decided to try and change my boot animation but when I restart my phone I still have the stock verizon one. I have received the 2.2 update and not sure if that matters. And I was wondering what are the requirement to make a boot animation. I'm a huge UFC fan and would love to have a .gift of a fight or something.
