[Galaxy S II Q&A, Help & Troubleshooting] DJViking:
I'm new to Android and have a few question that didn't get answered by Google it. I have bought my first Android phone (SGS2 of course, after years of being a Symbian fanboy), but have not received it yet.

1. Does everything run on top of Dalvik JVM? At the bottom is the Linux kernel. Then there is a Linux process which runs Dalvik VM. Could for instance Sun's JVM run on a Linux process of its own or another Linux application?

2. Can C/C++ Linux program run on Android? Though compiled for ARM. Android has NDK (Native Development Kit) which allows it to run C/C++ applications inside Android applications, but I'm wondering about running C/C++ applications directly on Android. BusyBox is coded in C, but runs on Android. Is it running directly on the kernel's linux process or within an Android application on Dalvik?

3. The latter(Q2) would indicate that not everything run on top of Dalvik. Otherwise C/C++ programs would not run.

4. Android uses ADB (Android Debug Bridge) for its CLI magic. BusyBox uses Ash. Can one install bash as the default shell, with full GNU Core Utilities commands? Some forum posts indicate that it is possible to install an ARM re-compiled bash version.

5. Android can be rooted by installing applications like Super User or BusyBox that would let the user execute applications as root. That would indicate that there exist a root user, in addition to the actual user. Is this similar to how it is on Linux? Can I define a password for the root user so that no applications can run root directly?

6. Are all user data stored in the database SQLite? User data is accessible through different applications, but how does Android determine access rights to it?

7. I have read that Android applications run on their own Linux process and are assigned a unique user ID. Does this mean that we can run ps to see all running processes or does it act like the Sun JVM just showing each VM process? However looks like different applications can run in the same process. Can these be distinguished or do we just the the once process.

8, Is the camera application (that some have made modifications of) a Google app or Samsung app? Just wondering since the former would allow such modified versions to run on other than Samsung phones, but given that different phones have different camera specs I don't see how this could go well.

9. Can the codes typed in the dialer be executed through a shell instead (adb)?
[Galaxy S II Q&A, Help & Troubleshooting] RogerPodacter:
There are some apps that run direct c++ code. The stock gallery app for example is written in c++. So not everything uses that dalvik virtual machine. I don't know enough to answer all your questions though.
[Galaxy S II Q&A, Help & Troubleshooting] DJViking:
Not many replies. That is disappointing.

Perhaps I could move this thread to another forum here on XDA? Or perhaps another forum.

In the meantime I'll try some more Google search on the subjects...

[Verizon Droid Incredible 2] rm2011:
I have had just about every Android phone Verizon offers. And obviously, my latest is the inc2 which I love BTW. But I have noticed something- the amount of activity and or support for this device amazes me. Is it JUST because we don't have perm root yet? It seems like even peoples basic questions go unanswered because not enough people are around.

In no way am I trying to point any fingers or rush the amazing devs. I am just curious as to why there seems to be very little activity here. Could it be that people are already happy with their inc2 the way they are, so there isn't much rush to change it? I don't think so.. theres always bigger and better things to try and look forward to.

I came from a fascinate previous to this phone and had more problems with it than I could even begin to list. But the dev support was there. Hopefully its just the root factor causing the lack of support.. or maybe I am missing something. Please try to refrain from the flaming.
[Verizon Droid Incredible 2] xgunther:
Yes. Pair that with the fact that this isn't the most attractive "cutting-edge" device.
[Verizon Droid Incredible 2] SoCalSpecialist:
Neither is the Eris or the Hero but the amount of support they recieve is astonishing!! Even still to this day the threads and contributors continue to grow at a steady pace.

Going forward with what the op stated and as u gunther mentioned, its because we still dont have root. In time we will achieve root and shortly there after the threads and postings will grow as well.
[Verizon Droid Incredible 2] gigamchz:
I've herd others say this and I don't get it. It's a very high end phone! Second generation snapdragon with gpu and a front facing camera? I'de say its high end. Not a tb but not many phones have dual core or Tegra 2 yet. Plus 4g is too much. It sucks battery and its not covered enough yet. 3g is just fine for me. Its the best phone Verizon has at the moment. The battery is great, its fast, amazing build quality and the video chat is a nice plus. I call it the thunderbolt's little brother.
[Verizon Droid Incredible 2] ACD168:
Give it more than a little over a month.. this is why I keep my inc1 to play with. it'll come..
[Verizon Droid Incredible 2] thenickisme:
I believe the issue is that HTC has given us an ounce of hope by telling us that they will no longer lock their bootloaders. By doing this, most people are hesitant to try and root their phone since they know that HTC might do it for them. (Or provide an automated solution, of course.)
[Verizon Droid Incredible 2] nimdae:
Sure, it's not a tbolt. Differences:

tbolt has 4.3" screen, I2 has 4" screen

tbolt has LTE, I2 does not

tbolt has a kickstand built in, I2 does not

...

...

Do you find these differences revolutionary? Because that's pretty much the only real differences. They both have the same SOC (2nd gen snapdragon), same 768mb RAM, same cameras, etc. The core hardware is pretty much the same. Unfortunately the storage controllers are different enough to make the rooting process for the tbolt not work for the I2, but it's my understanding they are similar enough that a similar hack is being worked on.

(this isn't targeted at gigamchz, just expanding on what was said)
[Verizon Droid Incredible 2] rm2011:
I agree completely with nearly everything stated. What would you guys think about starting up an IRC room for us "non-devs" ? Ive got one setup, but if nobody is interested in making use of it, I don't see a reason to move forward with it.

I was only thing Irc because its a lot easier to get an answer to your question quickly. And also there would be a strict rule of no flaming. So hopefully people would feel more comfortable asking questions.

From the Market. Which is really strange. When I denied it, it forced closed but I was able to restart it again.
[Streak 5 Q&A, Help & Troubleshooting] hake101:
I am hoping one of you guys might have an address for Dell's customer service for the UK. My Streak has been away for over a month and it looks like UPS might have lost it but I am having no luck with the phone lines- it seems there is only one person who can chase the tracking details(!) and he is off for a week...

I have looked all over the Dell UK site and cannot find an actual email address for support only forms to submit.

Anyone have a similar story or any idea how long Dell give themselves to repair a unit - for instance if this was a PC purchased from my company we would have replaced it by now!
[Streak 5 Q&A, Help & Troubleshooting] Kumouri:
I'm not sure if they sent it to Dell (I'm pretty sure they did) but both times I sent my Streak in for repair through Best Buy it took at least a month. I think it takes Dell a long time to get the parts for repair. Not sure why, though.
[Streak 5 Q&A, Help & Troubleshooting] hake101:
Yep I don't mind if it takes a while to repair normally, what worries me in this case is they don't know where it is!
[Xperia Arc General] gourdouli:
About ten minutes ago, my phone displayed a notification that an update was ready to download. I thought this odd, because I was on a bootloader unlocked phone running .184 and rooted via gingerbreak.

It downloaded the update in about 5 minutes, then asked me to OK the installation. The phone powered down, and rebooted displaying a box with an arrow, along with four dots.

Then it stopped, and my phone is now cold. Seriously cold - no lights when charging, unable to get it to work with flashtool...

If you're running an unlocked bootloader and it asks you to update - don't, until people confirm that this was just a blip for me.

UPDATE: Holding the back (not menu) button and plugging usb cable in causes the led to light up green, but still not detected by fastboot or flashtool.

[Xperia Arc General] cherryfish:
That should be a sticky thread somewhere. oO
[Xperia Arc General] BluechipJ:
Just for clarity:

Unlocked bootloaders don't mean you won't get OTA updates. Sony has confirmed on Facebook and Twitter that as long as you're running an official Sony firmware, you'll still get updates. It's only when you're running a completely custom (e.g. Cyanogen) ROM will you have to update manually.

But back to the OP, that sucks that the update messed up the phone.

anyway to turn auto updates off? there must be a way some how? surly

I was using the rooted hk 2.3.2 firmware posted in the dev forum.

No idea about charges yet, will let you know how I get on
[Xperia Arc General] hellocng:
No problem with OTA update for me. The phone powered down and rebooted with the four dot screen and after the progress bar reached the end for the first dot, the phone turned off for a few minutes and came back on loading the second dot. There is a slight delay between each dot. The whole time USB was plugged in with USB debugging on. The fourth dot may restart the phone more than once but completed the OTA update without a problem.

For the bricked devices, have you tried pulling the battery out for a few minutes and turning on the device again?
[Xperia Arc General] muguet001:
I was grieved to hear that

In china many people use OTA update 2.3.3, then ARC dead,both locked and unlocked.
[Xperia Arc General] zenkinz:
The thing about ota update is there's no much of visual progress esply during initialization during and after an update. The blank screen can be as long as 30sec.
[Nexus S Q&A, Help & Troubleshooting] hal752:
Hi all,

I have just purchased a Nexus S and I'm really looking forward to it.

In the past I have had a Xperia x10, Dell streak and a Acer A500. So I think I can safety say I know what I'm doing :-).

As you can see I have never had a devphone and I was wondering is there anything I need to know?

I also had the choice off a Nexus one. Did I make the right choice? (Kinda silly asking in a nexus s forum but I would like people to be honist)

Thank you
[Nexus S Q&A, Help & Troubleshooting] zephiK:
Right choice of what? A dev phone is just like any other phone except there are two special things about it:

- Updates come directly from Google (unless you root / custom ROM but there'll be a deoxed version of the stock ROM shortly so it doesnt matter)

- Unlocked bootloader (fastboot oem unlock)

NS vs. N1.. they are two different phones from two different generations.

The Hummingbird CPU > N1 CPU (Snapdragon) due to its graphics power.

But if you were looking at specs, you'd be looking at dual-core phones.
[Nexus S Q&A, Help & Troubleshooting] hal752:
Right choice between the Nexus one and Nexus S. I love the idea off the support behind both off them. The dell streak had DjSteve. And the x10 had a few more but nothing like the nexus devs.

I was looking for updates which is why I went with a nexus. I have my tablet for its dual core.

[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
Is it actually a charge or is it "pending"? Pending charges will be removed. It is Google's way of making sure your credit card is good.
[Epic 4G Q&A, Help & Troubleshooting] Nabisco_12:
idk it just says google 4 1 dollar 2 times...
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
My credit card shows pending charges that don't always become actual charges. Like Redbox, if I use a free rental code. It shows $1 pending for Redbox but after a few days it just falls off. Didn't know if your card did that or not. Contact your credit card company if you think they are unauthorized charges.

Search around, I had the same issue as you but I needed to have the SBF file in the root "C:\" directory. I think RSDLite has some directory dependency where it expects the path to the file to be something specific. Good luck!

[myTouch 3G, Magic General] legolittlebrick:
I had the same problem some days ago and i tried almost everything i found on the web, but nothing worked.

At least i solved the problem replacing the market app (vendor.apk) with a most recent one.

To do this you need a working vendor.apk (i grabbed from a most recent rom) and a file explorer who can use root to copy file in /system/app (like ES File Explorer or Root Explorer).

Now simply replace vendor.apk.

This worked for me
[myTouch 3G, Magic General] mumilover:
Or you could just re-install it.

Use my APK installer tool and check the "re-install" box.

This will overwrite the apk file but not mess with the configuration...

Just like what you suggested :0)

Thanks for all the help! I did what you suggested and tried to replace the android market with a newer version. I couldn't do a direct install with a new APK, someone said you have to uninstall the old APK. I decided to try just flashing a new gapps; I got the files from this thread http://xdaforums.com/showthread.php?t=909067

[G2 and Desire Z Q&A, Help & Troubleshooting] waydownsouth:
Depending on their design, some switched-mode power supplies will emit a faint "eeeeeeeeeeeee", it's usually nothing to worry about as it's just the internal circuit doing its thing.

However, if it starts getting louder then it could be a sign of capacitors failing.

Best practice is to leave it switched off when you're not charging your phone...

Hello,

I would need to decompile the apk with the wallpapers, but when I create the new apk with Eclipse and then I load it in the mobile phone... 1- It does not install, or 2- The application crashes.

I have used programmes such as autoAPKtool, apkmanager, autoDeoTool and with all of them I get the same result.

My aim is to translate it into several languages and something else if it comes to my mind. This could be done by adding a values-en folder (english, for example) + strings.xml (this one with its language), but it keeps on crashing.

I hope you can help me, I would like to work with Eclipse.

To sum up, I am looking for the source to work with it.

PS: crash = screen turns black.
