I have android lollipop 5.1.1 on my Samsung Galaxy Note 4. I would like to have an app start with my smartphone's boot. It's a call recorder app (automatic call recorder). How can I do that? Is that possible without root?

I need to force a selected application to start up each time my Android-based device is (re)started.  Is there anything I can use (configuration setting, external application etc.) to accomplish this task? Or is this kind of behavior limited to home screen managers only?

I have made a sound based installation using OpenFrameworks and Puredata that runs on Ubuntu 12.10.  I need the installation to run continuously for days together. When the power goes off, i need the apps to start automatically on reboot.  My problem is, I have got everything installed in the root account because that is how few of them would run. So i need the system to run those programs as root without asking for a password.  Somehow it sounds very silly to me but I guess there must be a way to do this.  Any help/pointers are appreciated. Thank you

I want to find a way to restore my phone in case the process of rooting my phone or dual booting a custom rom breaks it. However, most of the ones I've looked at require the phone to be rooted before installing. I know I can create a nandroid backup through system settings, but I don't know how to recover that without rooting my device, or if there are better options. I'm not terribly concerned for any personal data on my phone (I can backup my pictures pretty easily), but I mostly just want to be able reinstall Android OS or reset to factory default in case my device breaks. Thanks! Edit: I am going to ask a new question (one different enough to justify not simply modifying this one) with the new info I learned from the possible duplicate.

I know that on a rooted phone, it's reasonably normal to create a small ext4 partition for App2SD to use, but I'm not asking about that case:  I have a non-rooted HTC Desire running Froyo, and I'd like to format the whole of my SD card as ext4 instead of FAT.  I'm aware that this will mean that Windows PCs won't be able to use the card, but all my PCs run Linux so they should be fine.  Will the phone be able to access and use the card in this case?

Is it possible to flash a smartphone like the Samsung Galaxy SIII or an LG Optimus 4X with a vanilla Android ROM like the one that has been flashed on Galaxy Nexus or Motorola phones (I think)?  I am asking because manufacturers like Samsung, LG, HTC tend to make ROMs for their smartphones and tablets with preinstalled launchers like Touchwiz or HTC Sense. They explain their decision by saying that they want to make their devices to look unique against their rival devices. The problem is that Android updates for their phones and tablets get delayed and there are incidents in which some devices - which are more than capable of running the upcoming version of Android - fall way behind or never get updated at all.   So, what I am basically asking here is if there is a way to install vanilla Android, excluding CyanogenMod or any other modified vanilla ROMs, on an Android based smartphone?

On a Samsung Galaxy S4 Google Play Edition running 4.4 and non-rooted (I'd prefer not to root a device used for professional development purposes)  Having stored some ebooks on my external SDcard, I decided that I wanted to add some audio as well (as my internal device storage is quite full.)  As far as I can tell not one app (nor adb) can perform any write operations to the external SDcard's root directory.  The one exception that I've found is that my ubuntu computer, can create and rename directories inside /storage/extSdCard/Android/data/ even though none of my apps can.  Is there a workaround for this that doesn't involve rooting the device?

I know there was a discussion previously BUT they didn't talk about security. E.g.: if I root my phone will all my apps run with root permission?  Related:

I am having some problems with my Samsung Galaxy S2 and I want to start an fschk session on the device.  So, I installed Android SDK with platform-tools. I can access to the device when it's normally rebooted but I couldn't list and connect to the device when it's in recovery mode.  How can I connect via ADB when the device is in recovery mode?

I will have a few Android phones that I will have to let go.   I would like to make a proper clean wipe of the data, without no one being able to retrieve them, and do a factory reset.  I have read about the , encrypting the device before doing a factory reset, doing both, etc.  Since I am not an Android/adb guru, I would like to know if some of you would have some idea on how to achieve this with certainty.  I know "certainty" is a big word when it comes to proper data erasure on flash memory but still.  I have found some answers here and somewhere else, saying that encrypting and doing a factory reset on your Android device is enough, but I could not find a reliable source.  Just a few information that could be useful:   I'm running Linux as my OS and, therefore, I'm not looking for a Windows-based solution My devices are non-rooted and (almost) identical (Samsung A510F + 1 A510FD)

I am able to backup my app's data from the root/data/data/you.package.name directory by just moving it to SD card manually. however, when i reverse the process,                                                                                                               AKA paste the data back to simulate a restore, the app just force closes, i have tried it with a bunch of apps and noticed the same reaction. Where am i wrong?

A couple years ago, it was easy to root any device: Install KingRoot, KingoRoot, or a similar app, hit the large ROOT button, and let it do the rest. After 5 minutes or so, a green "Root Succeeded!" prompt will pop up, and we can choose to keep the root app, or uninstall it and install a clean root manager app like SuperSU/Superuser.  How do they work? Why aren't they working anymore? And if they work, should I use them or not?

From the user's perspective when switching on the phone, I see two boot animations in my  running CM10. The first animation is from LG and the second animation is from CM10. Then it settles in with a locked screen ready for my input. What happens behind the scene (screen) during a boot process when an Android device is switched on? It will be helpful if the answers can help a non geek to understand various process and jargon (like, fastboot, bootloader, recovery, if applicable, etc.) regarding boot sequence.

As I understand it, Android Lollipop (5.0) is now generally available over-the-air. My Nexus 4 briefly offered for an hour or two to install it. I said yes, and watched it start to download. When I next went to unlock my phone, it obviously wasn't installed. Now, when I go into the Settings app, and manually check for updates, it says my phone is up-to-date. It's still on Android 4.4.4.  I don't particularly want to install the developer image, as that'll wipe all the data from my phone. Is there any way I can encourage it to update?  I'm in the UK, if it's relevant.

So, yesterday my phone took a serious tumble.  It is now essentially useless, as the screen either fails to turn on, or when it does, there is nothing useful to see (just lines of primary colors, mostly).  I believe (from the fact that it still chirps at me when emails come in, etc), that the phone is still functional, otherwise.  I would like to perform a full system dump, so that I can get off any files from the phone (a TMobile SGS2 (hercules) running slimrom 4.3 build 1).  The sdcard probably isn't important, as I can just pull it, but the phone's own internal storage I should like to get a copy of.  When I plug the phone into a usb port, it 'mounts' the usb via MTP, and I can see all the files.  Unfortunately, when I do a select all | copy | paste operation, the paste op dies before transferring all files.  I've tried a couple other ADB shell operations, in hope of flipping regular USB mounting on, but nothing has worked.  Any ideas how I can get a full dump of my poor phone's contents?  Edit  Currently running a adb pull /sdcard/ ... Its copying files presently, but its too early to tell if its going to get evertying I'm expecting.  Edit #2  looks like its going to work...its taking a rather long time, but it appears to be grabbing everything I was expecting it to.

I was going to install an app to my device from Google Play on my desktop, when I noticed a "No carrier Samsung GT-N7000" in my device list:    (the Nexus 7 is mine)  Apparently this device is the original Galaxy Note. I've never even seen one of these devices, and there shouldn't be one registered on my account. It doesn't show on Android Device Manager.  Is someone else on my Play Store account, downloading apps/media on my credit card? I use 2FA, so I'm worried about how that could have happened. Is there anything I can do to find out more about this device?

I tried to install Android's ROM and got ERROR 7, then I wiped out cache, data, internal storage, where was twrp.apk installed. After that I cant get into boot menu (with Install, Wipe... buttons). Then I copied twrp to the phone: sudo fastboot flash recovery &lt;twrp.img&gt; Tried versions 3.2.1-0 and 3.4.0-0, because I heard for certain phone (I have Xiaomi Mi4) it's necessary to use proper version, though I don't know which. What's going on now: I can successfully can get to the nice splash screen using Volume Down + Power, then on my PC I give sudo fastboot reboot command and press Volume Up + Power and here is the problem: It has no effect, it just keeps rebooting (I see only Xiaomi's logo).
