There is this xml file under frameworks/base.
/frameworks/base/core/res/res/layout/simple_dropdown_item_2line.xml
How can I inflate that in my own android application?
Here my application "com.android.hello" calls a core library "libvt.so" through JNI call. There is a segmentation fault in "libvt.so". When executed I get the following log What I see is some Hex value followed by a library name. #00 pc afe0d24c /system/lib/libc.so
Also there is a Stack section 01-01 00:02:57.800: INFO/DEBUG(1600): stack: 01-01 00:02:57.800: INFO/DEBUG(1600):bef2e570 bef2e604 [stack] 01-01 00:02:57.810: INFO/DEBUG(1600):bef2e574 afe0a333 /system/ lib/libc.so
This too gives similar information. I am looking for little more informations rather than Hex values. Like the backtrace feature where the stack hex values is mapped to the function names and function names are visible.
Please provide information how to see the function names in stack rather than Hex values. Is ther any compiler options needs to be updated? Any makefile to be updated to enable backtrace?
I'm writing a ContentProvider that will provide content that is not stored in a file or database.I understand hat I have to overwrite openAssetFile() method.My problem is that I don't know how to create AssetFileDescriptor from data in memory (byte array or stream).Can anybody please point me to the right direction?I was digging in Android source where they use MemoryFile but I can't obtain ParcelFileDescriptor from MemoryFile.

That is MediaPlayer will use ContentResolver.openInputStream() to play it. I have read a lot of discussions about this problem but no one had a solution yet. The most recent one was in January 2010: http://groups.google.com/group/android-developers/browse_thread/threa.
View 6 Replies View RelatedIs there a way to achieve the following in Android?
1. generate a Java stack trace in Android. In J2SE, we use to use something like this - send a signal to the Java Virtual Machine; the Java Virtual Machine generates a stack trace for you; or we can also use debugging tools or Java API calls.

View 7 Replies View RelatedI 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:
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.
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?
I downloaded the Android 2.2 source code and try to build it. When I executed the make command, I got an error here like this build/core/java.mk:20: *** frameworks/ex/common: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. Then I changed the frameworks/ex/common/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7. Next place, build/core/java.mk:20: *** external/jsr305: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/jsr305/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
Last one, build/core/java.mk:20: *** external/guava: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/guava/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
By these changes the code started the compilation.
1. Why the error occured?
2. Changes which I did is correct or not?
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?

The Server then asks the getPackageManager() and gets all the installed applications. But the getPackageManager returns the nullpointerexception. The Server is written in a java environment and is started from my android application.

View 5 Replies View RelatedThis may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

I'm not seeing any issues on any emulators or devices.
I'm moving a project to the new Android Native Development Kit (i.e. JNI) and I'd like to catch SIGSEGV, should it occur (possibly also SIGILL, SIGABRT, SIGFPE) in order to present a nice crash reporting dialog, instead of (or before) what currently happens: the immediate unceremonious death of the process and possibly some attempt by the OS to restart it. (Edit: The JVM/Dalvik VM catches the signal and logs a stack trace and other useful information; I just want to offer the user the option to email that info to me really.)
The situation is: a large body of C code which I didn't write does most of the work in this application (all the game logic) and although it's well-tested on numerous other platforms, it's entirely possible that I, in my Android port, will feed it garbage and cause a crash in native code, so I want the crash dumps (both native and Java) that currently show up in the Android log (I guess it would be stderr in a non-Android situation). I'm free to modify both C and Java code arbitrarily, although the callbacks (both going in and coming out of JNI) number about 40 and obviously, bonus points for small diffs.
I've heard of the signal chaining library in J2SE, libjsig.so, and if I could safely install a signal handler like that on Android, that would solve the catching part of my question, but I see no such library for Android/Dalvik.
How to trace the Memory Leaks in Android Development? I am working on eclipse IDE to develop the application. i cant find out how to rectify the memory or window Leaks Exceptions? Any Idea.
Mainly the Window Leaked error raises the Illegal Argument Exception? how to rectify both og this.
I have heard a lot about this code base, but have seen nothing.The possabilities are amazing, why are we so limited. If the sceen is multitouch capable, why not use it? When will we see a fix for the issue with the talk button on the headset, or the ability to run apps from the sd card, or the ability to stop running apps. This android os is linux based, yet these issues are holding us back? I am invested in this platform, and I really believe this is important. I hope to see more functionality. We have a platform that can truely compete with the iphone, but we must work hard to perserve our image.
