Android :: Matching Prebuilt Kernel Sources
Jul 10, 2009
I have a recent "repo" copy of the platform tree and I noticed that the kernel sources included in it are incomplete. For example, the arch/arm/mach-goldfish directory is not present, but devices from this directory are present in the kernel that the emulator boots. How can I get a more complete copy of the linux kernel sources? Are there tags for lining up these sources with the prebuilt kernel that is shipped in the platform tree?

I'd like to know more about porting C applications to native ARM for use on Android devices. I can make simple programs using the prebuild toolchain which comes with the source, but how can I use this toolchain with applications which are more than one file and require configure and make? (I'm trying with Vim for starters).

i'm trying to include a maven java project into my android project. the maven project is the greader-unofficial project which allows developers access to google reader accounts, and handles all of the http transactions and URI/URL building, making grabbing feeds and items from google reader transparent to the developer. the project is available here:
the code is originally written for the standard jdk and uses classes from java.net that are not a part of the standard Android SDK. i actually tried to manually resolve all dependencies and ran into a problem when i got as far as including com.sun.syndication pieces required by the class be.lechtitseb.google.reader.api.util.AtomUtil.java... some of the classes in java.net that are in the standard jdk (i'm using 1.6) are not in the Android SDK. in addition, resolving all of these dependencies manually is just ridiculous when i'm compiling a maven project that should be pretty simple.
however, i can use maven to compile the sources with no issue. how can i include this maven project, which is dependent on the complete jdk, into my android project in such a way that it will compile so that i can access the GoogleReader class from my android project? and for the record, i don't have the expertise to rewrite this entire api to work with the standard Android SDK.

I'm trying to build CM KitKat for the Optimus S/V (unsupported by CM). The build is crashing out trying to link libwebviewchromium.so.It gives dozens and dozens of errors like this: external/chromium_org/content/browser/android/browser_media_player_manager.cc:70: error: relocation overflow in R_ARM_THM_CALL
At the end it prints this:
collect2: error: ld returned 1 exit status
make: *** [/home/dbrown/cm11/out/target/product/thunderc/obj/SHARED_LIBRARIES/libwebviewchromium_intermediates/LINKED/libwebviewchromium.so] Error 1
It may be a problem with insufficient memory on my build machine (Core 2 Duo laptop with 3 gb ram). For the time being, or in case that's not the problem I'm looking for a work-around. I looked in the Android.mk file for external/chromium_org and saw this:
# Don't include anything if the product is using a prebuilt webviewchromium.
ifneq ($(PRODUCT_PREBUILT_WEBVIEWCHROMIUM),yes)
how can I add a prebuilt webview library so I can get past this error? I just want to get something built for now so I can test it. This would be the first successful build for this device.

I have two vertical TableLayouts containing rows of TextViews separated by some graphics. Something like this:
R-L Graphics R-R R-L R-R R-L R-R R-L R-R R-L R-R
The R-R TextViews have a fixed width, which means they grow vertically when the text is longer than will fit in the width. The text is set at runtime so this height is not known in advance. I want the height of the R-L rows to exactly match the height of the R-R rows with the R-R rows being the reference source for the height. Once I do a TextView.setText and a TextView.setWidth on the R-R TextViews, the height of those TextViews should be determined. Then I can do a TextView.setMinHeight on the R-L TextViews. But I'm having trouble getting the height value from the R-R TextViews. The TextView.getHeight method returns zero.

I'm trying to install a prebuilt binary in a custom Android image. For that I have copied it to a new directory in prebuilt/android-arm/ with an Android.mk file similar to this one:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := binary_name
LOCAL_MODULE := binary_name
LOCAL_MODULE_CLASS := EXECUTABLES
include $(BUILD_PREBUILT)
So if I run make system_image binary_name, the binary file is copied to /bin/ in system image. And if I run the emulator I can see the binary file in /system/bin. The permissions are the same as the other executables (-rwxr-xr-x) and, according to file, this is an ARM binary (ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), stripped).But when I run it on the emulator, it says:
# binary_name binary_name: not found have straced it and this is what I can see: # strace binary_name execve("/system/bin/binary_name", ["binary_name"], [/* 9 vars */]) = -1 ENOENT (No such file or directory)But the file is there, and strace is able to find it.Any idea of what can be happening?UPDATE: As Kristof says, this is probably a problem of dynamic linking, but I don't have ldd for Android ARM.

I wrote an app that, among other things, renders feed articles using WebView. Now I get error reports that seem to originate in WebView:
-- NewsRob Version: 1.7.0/170 -- Android Version: sdk=2, release=1.1, inc=128600 -- Thread State: RUNNABLE -- Stacktrace: java.lang.NullPointerException at android.webkit.CacheManager$1.run(CacheManager.java:391) at java.lang.Thread.run(Thread.java:935)
I've got another report with the same content, but a different incremental version of the sdk (126986). Probably one from the US and one from the UK. So now I would love to know why the code blows up and if there is anything I can do about it. And with the source files and line numbers I felt in good shape to so. If only I could match them to the public code repositories ;-(............................

I've been trying to organize the phone numbers in my address book so that:The phone calls I receive show the contact name (and not only the number).
The SMS messages I receive show the contact name (and not only the number).Android is able to join the WhatsApp contact with the main contact based on the phone number.
I live in Brazil and the phone numbers have a few particularities: you can include the country code or not (55), you can include the city code or not (which is usually prepended with a 0), you can include the phone carrier code or not, etc. So matching those numbers is not a trivial problem.
I have the impression that Android has an internal logic for dealing with this issue. But it's not working particularly well for me. If this logic is configurable?The issues I'm having right now are:The numbers shown in the SMS messages don't have a consistent pattern:

I have a TEXT column and I want to match all rows where the value has a certain prefix. For example, WHERE mycol LIKE 'myprefix%' However, I noticed in some optimization guidelines that this will not use the index and instead you should do this:WHERE mycol >= 'myprefix' AND mycol < 'myprefiy'Instead of simple A-Z chars, I have a whole variety of UTF-8 chars (think chinese characters).My question is, how to work out the next char in UTF-8? Is it enough to add one to the codepoint,

We have ported android to our hardware. I am facing some issues related to sdcard. Here is the test scenario and issues:
First issue :
1. On hardware, insert the card and copy a file to sdcard using dd command.
2. Remove the card from hardware.
3. Do ls /sdcard. It shows the file present in sdcard. It seems unmount of sdcard device is not happening.
Second issue:
1. Copy a file to sdcard using dd command.
2. Remove the sdcard and check the content of the sdcard from PC. File is not visible.
3. Copy file to sdcard again and then check the content of sdcard from PC. File size is zero bytes.
4. Restart the hardware and copy the file again. File is visible when checked from PC.
Third issue:
1. The content of copied file are not matching with the original source file.

I have the sample code packages for eclipse installed. On the webpage about Searchable Dictionary v2 http://developer.android.com/resources/samples/SearchableDictionary/i... it is noted that the project source code is contained in the SDK. But the SDK only contains V1 without database usage. Can the souces be downloaded somewhere else?

Kept log in on Change() method, observed that it is not getting called, any clue that where it might went wrong.

I have a number of different calendars on Google calendars all with different colours. I have recently started a job that uses Google Calendars too and so have imported these into my account. However, when I sync them, the colours of each calendar do not match the colours on Google Calendars online. My original 3 calendars colours are all correct, but the recent ones I have added all appear red on the Desire's stock calendar app instead of the colours I have assigned.

Is there anyway to bypass 'Unknown sources' setting without having the application actually downloadable in the market? Signing up for the market is fine but I do not want the application actually available via the market due to partner restrictions. However, installation should be smooth without requiring the user to allow installation of application from non-market applications.

I would really appreciate if someone could point me to a list of devices/carriers where install from unknown sources is not allowed.
For e.g. I can confirm that HTC Aria (offered by AT&T) does not allow install from sources other than market.

Has anyone got a good source for icons that can be used in an application?
I'm thinking of things like pushpins, scope sights, house, car, shop, and other small graphics you might overlay on a map or picture.
Most people just rip them off from the web, but I'm looking for an honest source.
A while ago, I found a website marketplace where you could commission stuff from graphic artists. Does anyone have any links for these? The sort of thing I mean is like this: http://www.graphicster.com/Default.aspx (But those guys haven't got critical mass yet). Or these guys http://www.crowdspring.com/how-it-works/ (but they seem a bit high end).
