Android :: Can Boot Into A Single Application On Boot

Oct 24, 2009

How easy is it to make an application that's just a wrapper around the browser? Can the Android OS boot directly into that application so that only a certain application launches after boot. I'm building a client some custom software and I'd prefer to use one of those Archos 5 MIDs than a Linux netbook.

General :: Android Boot Sequence And Backup / Access To Boot / Recovery Partitions?

Oct 4, 2012

I try to understand android boot sequence on my JB (under CM10). I found some docs and there should be specific partitions (boot, recovery, system, cache, data).

My understanding of the boot sequence is now:

A) normal boot:
1) Power ON ->
2) bootloader ->
3) boot-partition where i flashed the kernel aka boot.img ->
4a) system-partition with the OS (libs, UI, etc) where i unpacked over CWM my customROM.zip ->
4b) data-partition, where i unpacked google-apps.zip and installed all the apps ->
4c) cache-partition with user data

B) recovery boot (adb reboot recovery):
1) Power ON ->
2) bootloader ->
3) recovery-partition with CWM where i may unpack all the .zip stuff to proper partitions, or restore from sdcard, etc.

Is this correct? I wonder, because i didn't installed CWM into recovery-partition. It cames from install of CM10 (fastboot -i 0xfce flash boot boot.img), so it must be in boot-partition and not in recovery?

So, next confusion: i looked up to /proc/mtd and i don't see neither boot nor recovery partition here:

Quote:

# cat /proc/mtd
dev: size erasesize name
mtd0: 19000000 00040000 "system"
mtd1: 00600000 00040000 "appslog"
mtd2: 06580000 00040000 "cache"
mtd3: 1a400000 00040000 "userdata"

I did a backup with CWM and loocked the data. There aren't boot, and recovery backups:

Quote:

# ls -lha /sdcard/clockworkmod/backup/2012-10-04.18.49.55/
d---rwxr-x 2 system sdcard_r 4.0K Oct 4 18:56 .
d---rwxr-x 3 system sdcard_r 4.0K Oct 4 18:49 ..
----rwxr-x 1 system sdcard_r 1.6K Oct 4 18:54 .android_secure.vfat.dup
----rwxr-x 1 system sdcard_r 54.6M Oct 4 18:55 cache.yaffs2.img
----rwxr-x 1 system sdcard_r 360.2M Oct 4 18:53 data.yaffs2.img
----rwxr-x 1 system sdcard_r 212 Oct 4 18:56 nandroid.md5
----rwxr-x 1 system sdcard_r 214.6M Oct 4 18:51 system.yaffs2.img
#

So, i think i didn't understand the boot sequence and partition schema corectly.

General :: How To Interrupt Android Boot Sequence To Force It Boot To Linux Kernel Only

Sep 12, 2013

I am trying to do some low level performance testing related to device processor cores through adb which I feel it is affected by Android background services and system stuff.

As I know that the Android boot sequence stages are as follow:

1.Execute Boot ROM code.
2.Execute the boot loader.
3.Load the Linux kernel.
4.Launch Zygote, which initializes the Dalvik VM.
5.System server which loads the Android system.

So my question is how can I interrupt this sequence to force it stop on stage 3 to load Linux kernel. This can implement my intermediary performance testings before loading again Android system.

Does Fastboot or Clockworkmod recovery can load my device to a kind of Linux kernel?

General :: Can Android Boot Logo Screen Be Configured To Show Linux Boot Logging

Jun 13, 2012

Instead of seeing the boring old Android logo or my service provider's logo, I'd love to see the standard text-based Linux boot screen that shows the status of all the hardware and configuration info as my phone boots. My current phone is an HTC EVO 3D running Cool ICS with Sense 3.6 and Revolutionary CWM.

Motorola Droid :: Won't Boot Past Cyanogen Boot Screen

Oct 30, 2010

I went to reboot my Droid because it was lagging a little and when it came back on it go stuck at the Cyanogen boot screen. I pulled the battery, put it back in and held the X to boot in recovery and my recovery won't come up either. It just skips right to the Motorola M and if it doesn't get stuck there it goes back to the Cyanogen screen.

I haven't made any changes to the phone at all so I am completely puzzled on why this is happening. I obviously can't take it back to Verizon since its rooted so if there is a way to fix this I really want to because I love my phone and my wife will kill me if it is screwed up.

Android :: Application Startup On Boot

Jun 8, 2010

Other than downloading a 3rd party application that auto-starts apps on boot, is there a way within the OS itself to autostart programs when the phone reboots? I have a few apps I use for work and would be nice if they autostarted on my Droid without having to launch each one independently.

Motorola Droid X :: Won't Boot Past Motorola Logo Nor Boot In To Recovery

Sep 16, 2010

I tried installing Tranquility and must have screwed something up because now my phone won't boot past the Motorola Logo. It's been sitting here like this for about 15min and I can't even boot into recovery by holding the power and home buttons. I don't know what else to do now. Idk if my phone is bricked but even if it is don't I need the SBF file to unbrick it and I can't find that file any where. I did a nand backup or whatever before doing any of this so hopefully that can help me. What should I do now?

Android :: Time To First Screen - Boot Up And Application Start Time?

Aug 25, 2009

at the moment I am thinking about a new app and need some information to decide whether to develop on Android or an alternative OS. I am particularly interested in "time to first screen", "boot-up time", "time to first Audio" and "app-start" (can be any from the android market or even one of the pre-installed ones) time? Does anyone know a source or perhaps measured those numbers?

Android : Multiple SingleTasks Within A Single Application

Jul 1, 2010

I have 2 activities declared as singleTask in my application. The reason for this is, with standard mode, pressing "HOME" in one activity (say A) and launching another (say B), still shows activity A.

However, a new problem arises because of this.

A -> "HOME" -> B (Result : B, Expected Result: B) -> "BACK" -> (Result:A, Expected Result: Home Screen) Any ideas why?

Android :: Files That Contain Boot.img?

Feb 8, 2010

I'm trying to guess what are the files that contain the low level code of the boot.img/recovery.img images. I tried modifying the .S files in the sub folders of "/bootable/bootloader/legacy/", but after a re-compilation the boot image are exactly the same as before my edits to the file(s) (Checked with shasum before & after the re-compilation). Also, I'm trying to avoid a "make clean", because a full compilation takes me about 3.5 hours

Android :: App To Choose What Starts Up At Boot

Aug 16, 2010

I have a number of app's that seem to start and run at random.

I still want these apps on the on phone, so don't want to uninstall, just want to be able to choose when they start up - rather than them starting at random and running in background.

Some of the app's running:

Music
Footprints
Stocks
FM Radio
Juiceplotter
Fake-call-me-Pro

Is there an APP similar to AUTORUNS (which I use on my Windows PC) that lets me choose what programs run at boot?
