Android :: System.nanoTime - For Dual Core Processors
Nov 12, 2010
We are running the DALVIK Virtual Machine tests from 057-iteration- performance/ suite, and we don't
There is a static table in test script which defines the various test timming. This table has hard coded values for al lthe expected results. Does this table have to be changed based on the platform whether its a Dual Core or single core? It's always failing with timeout errors.
We believe these errors are to do with how the nano seconds are measured. We have been seeing some issues regarding the API System.nanoTime(); when we run on a Dual Core architecture.
Has anyone seen problems with this API on a dual core architecture?

I just want to know a couple of things (NOT that I would ever try this myself but im interested in the info).
1) Is it possible to install quad core firmware on dual core tablet?
2) Is it possible to 'spoof' the android system into thinking 2 CPUs are 4?
3)If you install dual core firmware on quad core machine will 4 cores or 2 show up?

Anyone hearing any news on upcoming dual core releases. I'm eligible for upgrade on 12-1-10 but if something new is coming out I'd wait a few months. I'm with sprint and would like to stay with them, hoping they will have one of the new dual core releases.

I have an Atrix and I'm wondering are there any apps/Widgets that will show frequency of a core (doesn't have to show both as my second core is usually offline) in real time and that wont just stop functioning after an Hour or so.

So we just got our Vibrant, and guess what, in a couple months dual core will be here, and we know how fast time flys.
Honestly, with all this GPS crap going on, I didn't even get to enjoy my soon to be outdated phone.
Samsung will release a new dual core chip, and with graphics that are 5x that of what we have in our phone.
Samsungs dual-core CPU Orion coming to Galaxy this year? Android and Me
LG will release dual core also:
LG to deliver first dual-core Android smartphones in Q4 Android and Me
I'm kinda not happy about this, septemeber will be over soon, and those new phones will be 2 months away.
This is also just my opinion, but the slow pace that samsung and T-mobile are going, I bet Android 2.2 will be the last official update T-mobile gives us for this phone.
2012 brings quad core 2.5ghz

I've bricked my Onda Vi40 while updating it to 4.1 with clockworkmod recovery. I used the files that I've found from a forum post, but after flashing a file, an error occured (I can't remember the error message) and now, my tablet is stuck in clockworkmod. Also, I can't mount external sdcard, error messages appears as follows:
error mounting /sdcard!
error mounting /sd-external!
At my computer's device manager, the device can be seen as "GT-I9100" device, seems like a Samsung Device. I've found and tried to install the device drivers, but it's unsuccessful too.
As a result, my tablet stuck at clockworkmod recovery, it can't mount any sdcard, i have no access to internal memory.

I have a Polaroid 7'' Dual Core PMID702DC tablet with Android 4.1.1 Jelly Bean and I can't turn on Wi-Fi! When I turn it on, I got to Settings > Wi-Fi and it says that it's on but the button is gray and on the right it says 'Turning on Wi-Fi' but it doesn't turn on and a few minutes later it goes back to Off! I've whacked it on the back a few times and it doesn't turn on! What do I do?

Bought the Ainol AX1 Quadcore Dual Sim from Aliexpress. Everything is fine on it except that it reboots every now and then. It usually happens after charging. The reboot that happens is shorter than the normal manual reboot. I'm thinking that an upgrade may work but I do not know where or how to upgrade this device. I have an Huawei G300 Android phone that informs me automatically if an upgrade is available. For this tablet, an upgrade can only be done by downloading an upgrade file and loading it manually?

My first computer was a hand-me-down from my father. It had a Pentium II, 200ish mhz. I think it had 64 MB ram and a 2 gig hard drive. I'm pretty sure that my Eris is faster and better than this computer in every respect except for screen size, but I wonder, how does the Eris's processor compare to other x86 processors out there? Has anybody benchmarked arm based CPUs against old pentium CPUs? Does anybody know how our phone processors stack up against computer processors?

I know this topic has been covered a lot, so apologies if this is redundant. I would like to work in the SDK and simply extend a core app that already exists, and then override some functionality. For example, I would like to extend Contacts, but then overwrite the entire ContactsListActivity class, for my own experimental MyContacts.apk.
In this youtube video: http://www.youtube.com/watch?v=3aUjukCdPyQ
Dianne talks about the ringtone picker, did she just extend the core ringtone picker and work in the SDK?
I DO have the entire platform source code, and have made some changes to core apps there, but rebuilding takes awhile (even useing mmm, and snod), so I was hoping to speed up development by working in the SDK (where building and running the emulator seems to go faster). Not sure if this is realistic or not.
This is all just for some internal experimentation, I am not looking to contribute the the core apps.
In another post, someone had referred to ".... classes available in the SDK....". How can we see what classes we have access to, in the SDK.

I want to pass the build process the --core-libary option. But in ADT I don't see such an option. So in Version 1.1 --core-library could be inserted into the build.xml and build was successfull when using ant. It looked like this:
CODE:..........
In 1.5 build.xml as well as the hole build process was heavitly altered. Now even the dx.jar is gone. The build.xml works differently, and I dont see where to put --core-library. There is also no documentation for where to put it.

I'm installing the Android SDK on a fresh installation of Fedora 14 (Linux).
I installed eclipse, and ran the tools/android sdk tool to install all the Eclipse components for the SDK.
I was able to get DDMS to install when selecting it by itself.
And for the last component - the Android developer tools, I'm getting the ugly error message pasted below.
Now I'm Stuck in Eclipse dependency hell.
I've searched through the available packages in Fedora and I can't find the one that has the files necessary to satisfy this Eclipse dependency...
Can anybody please translate what it is that Eclipse is asking for and what Fedora package it lives in?
The error:
Cannot complete the install because one or more required items could not be found.
CODE:.................

I am using Eclipge Ganymede for Android. While developing a project i clicked on FIX PROJECT option by mistake. Then the whole project started showing an error. I have been displayed the following log in the console...
trouble processing "java/math/RoundingMode.class": [2010-04-23 17:24:29 - Gorinka2] Attempt to include a core VM class in something other than a core library. It is likely that you have attempted to include the core library from a desktop virtual machine into an application, which will most assuredly not work. If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine binary, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message. If you go ahead and use "--core-library" but are in fact building an application, then please be aware that your build will still fail at some point; you will simply be denied the pleasure of reading this helpful error message.

Now i couldnt run the run. Its showing errors. So, help me out in setting my project to normal state...

We ran core tests by the command "/development/testrunner/runtest.py - v --coverage core" and got coverage report successfully. But the reports says all are 0%. We ran apidemos and got coverage report which looks good.
Below is the console output for core tests:

So I wonder why core tests's coverage report says 0% and how can I make the report make sense.

I am interested in integrating Scala (or some other non-Java JVM-language) into the android platform. I am not referring to writing an android application with Scala, that I did early early on, but actually hooking into the build process that builds the android platform source tree. I imagine this will be a matter of hooking into the makefiles and such. Does anyone have insight into this?

Can a core class such as "AbsListView" access resources, such as xml files, and .png's, in a 3rd party app installed in the normal way (at the app level)?
I realize this is a change in framework code, and that is fine for my purposes. So, for example, if I know that I am going to install an app called "MyApp", could I go into frameworks/base/core/java/android/ widget/AbsListView.java and tell it to use an xml file and .png's that live in that app? Here is the line I would want to modify: setSelector(getResources().getDrawable( com.android.internal.R.drawable.list_selector_background));

I need to build a java.beans.PropertyChangeListener which is part of JDK (rt.jar) but not part of Dalvik.
Trying to copy the sources to my Application I get this:

My solution: 1) build a core library with consisting out of java.beans.PropertyChangeListener 2) integrate that library (jar?) into my application.
My question: - how can I build a core library using eclipse?

Is there any way to access core Android functions like app switching (holding down the Home button for a few seconds), to be used in other contexts? Similar to how you can access Activities from the apps installed and use them as Shortcuts.
What I'd like to do is this:
press Home -> bring up app switching interface
long-press Home -> go to Home screen
Basically I want to reverse the two functions that short and long pressing the Home button does.
If not that, I'm also interested in being able to access the "app switching interface" via a Shortcut (like a Shortcut you place on your Home screen), or via an app.
For example, you can long-press on the Home screen and add a Shortcut (different than adding a shortcut to an App) which basically includes various context functions of some of the apps you have installed. I want to be able to do this - add a Shortcut - in which the Shortcut I add launches the "app switching interface" that you normally get by long-pressing the Home button. That way I can put that Shortcut in Wavelauncher or wherever else I want to be able to app switch without the annoyance of having to long-press something.
