View 7 RepliesI 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'm attempting to port a normal Java program over to Android, however I am having a problem with a huge number of missing Java packages (e.g., Android Java does not have java.lang.management). Is there a way for me to work around this, such as by adding the Java modules that I need?
View 2 Replies View RelatedI currently have an application using the libraries swing, swing.table, and awt on a java applet that I have running. I want to know what are the steps to get the application running as a native android app. I heard that I could use programs like Phonegap to just release a web based app for multiple platforms, but I am new to Android Programming (so far I just made a Hello Android app). I searched swing and awt, but I could not find any useful info.

I am working on a on-screen keyboard for Android, and I need to recognize starting points, turning points and end points of lines drawn by the user on the keyboard. A simple straightening function would be nice, as it is difficult to draw a perfectly straight line even with a stylus, not to mention finger-only touchscreens today.What I am trying to write is something like Swype. Any good libraries that I can use or make reference to?
View 1 Replies View RelatedAs I am very pissed off of using the emulator to develop any Java class, I thought of setting up a project in Eclipse and instead of the usual JRE I linked to the Android.jar (version 2.1) that usually the Android projects link to. I don't mean to use this to develop Layouts or other specific platform things, I was just trying to create a class that uses HttpClient.
It miserably crashes like this.
CODE:.............
I mean I'd like to develop libraries (and test them) so that when I go to the emulator I don't have to deal with them. Is there a good way to do this? This seems not to work for some reason.
Does anyone know of any video encoding/decoding libraries written entirely in java? Bonus points if it works on Android. I'm trying to write a video decoding application for android, where I have access to the frame level decoding functions (which is absent in the android API MediaPlayer class)

i know that in spring there are validators for various different types such as checking if a value is a int, if a value is a valid email, etc etc.
Anything similar in core Java or even android?
cheers in advance. i don't want to re-invent the wheel if its already been implemented. i could always sue Java reg expressions to construct my own ones but was wondering if their was one done specifically for email formats.
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?
Hi Android Developers, "Android includes a set of libraries which provide MOST of the functionality of the Java libraries". Does anyone know what is ment by MOST and which libraries are NOT supported compare the the JVM?
View 3 Replies View RelatedI've been contemplating (re)building an app on iPad for some time, where I would use objective-C and DSMI to send MIDI signals to a host computer. This is not bad (I mean, except for actually writing the app).Now I'm contemplating perhaps developing the app for Android tablets (TBA).In Java, what options are available for MIDI message communication? I'm quite familiar with javax.sound.midi, but then I would need a virtual MIDI port to send messages to the host.On the other hand, if the app were done in Adobe AIR, what options would I have available for communicating with MIDI?Obviously another option is to send/receive messages over a TCP/IP socket to a Java host, and talk that way, but it sounds a tad cumbersome... or perhaps not? DSMI does use a host program, after all.
View 1 Replies View RelatedI 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?
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.

I was really excited today when I saw the Tools r7 and ADT 0.9.8 were available and the latter had this note;
Fixes problems with handling of library project names that contain characters that are incompatible with the Eclipse path variable. Now properly sets up the link between the main project and the library project.
I create the library (foolib - no spaces, no caps, no punctuation). So far so good. I go to the main project, go to preferences --> Android. In the library box I add the new library. It appears. I press Apply. I press OK.
Nothing happens.
I return to the preferences, the library is no longer there JUST LIKE BEFORE.
I looked around for info on this in the group but couldn't find any... so far in my OpenGL programming I've just done everything directly, but I was curious if anyone had written any "wrapper" libraries for it besides min3d. Min3d is great (or is getting there) but it's GPL'd, making it unsuitable for a commercial product (if my understanding of the license is correct).
View 5 Replies View RelatedWe have been using gdbserver to debug our JNI code as follows. We have been less than successful -- breakpoints do not always get activated, sometimes we get SIGILL, and we seldom ever get a useful stack when the debugging stops on SIGSEGV, sometimes the program dies with SIGTRAP!!!
We have occasionally been able to have debug sessions with s/n, but since pretty much every SEGV has resulted in either a damaged stack, or at least, gdbserver can not find the stack, it's a pain.
Is there something we are missing? Is there some reason to use the 4.2.1 vs 4.3.1 toolchain? (Why are there two toolchains? I assume because of bugs in each that are fixed in the other... which bugs?)
We guessed that the "dalvik" process that we wanted to debug was app_process --- we found this out by looking at /proc/XXX/cmdline on our running activity.
This is what we do typically do(repo sync directory is in /build/m1 for me)
invoke:/build/m1/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi- gdb
(some of us use -tui, some of us run it under Xemacs, etc.)
We then do:
CODE:..........
We then start our activity, adb shell, discover the PID of the activity, discover the IP of the phone with "netcfg", and:

This is with a physical device. With an emulator, one has to, of course, run the adb forward stuff. (Too bad that doesn't work with a real device too, as then I would not need to run gdb over the wireless)
