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?

My app uses location services, and has the manifest entry:
<uses-library android:name="com.google.android.maps" />
Does anyone know if these libraries are guaranteed to be included on every Android phone? If not, how would I know if they are not there?
I'm writing an android app where I need to use AES. Is it better to use the bouncy castle libraries or should I just stick with what is included in default android libraries?

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.

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'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've been attempting to use the <include> tag in some layouts and it seems that these are of limited use because of the flat namespace of the R.id.x approach.
Suppose I have a layout (attribs and xml namespace decl omitted for clarity).
CODE:.......
Now in my java code I have a conundrum. I am not able to identify each individual instance o f the children included layouts root view. In the include tags I can replace the root id with "row1" and "row2" so I can find the individual linear layouts using findViewById
eg:
CODE:.........
However, I can't easily access the two instances of the TextView which are children of row1 and row2 because all I have to play with is the single id "text"
ie:
CODE:..........
In this case, which instance (row1.text or row2.text) does this refer to, both of them, or none?
I guess I would need to use another means of accessing the children of row1 and row2.
I have in many of my screens that re mostly constructed of LinearLayouts a FrameLayout that should take up the bottom leftovers of the screen (using layout_height="0dp" layout_weight="1") inside it there's a FrameLayout with gradients background and in it's middle with some padding lies a button with some text, naturally i need the text and onClicked properties to me different from screen to screen. I considered using <include > tag for the above compound in my layouts, but as far as i can see i can't really change (at least not in xml) the button text and callback, is that really so?

I can look at the source of the other apps to see what's available, but the GMail app is closed source so I'm not able to go that route.

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)

View 3 Replies View RelatedI cannot run android junit tests for classes sitting in main android project that implement interfaces that reside in other included projects. Depending on SDK version I get different errors: from "Test run failed:" on 1.5 and 1.6 and spurious process death to a more polite "NoClassDefFoundError" on SDK 2.0. This happens only on instantiation of classes that reside in the Android project and implement interfaces residing outside that android project. There is no problem instantiating classes that do not fall into this category (i.e. android only or library only classes).
Android project by itself works fine with these classes - it is just the test set-up doesn't and project inclusion/classpath seems to be ok. Test project includes all projects that main project includes. NoClassDefFoundError makes little sense here given that the classloader can see and instantiate classes sitting right next to the ones that do not work. Did anyone else run into this or found a way to set-up android based tests in a multi-project set-up? Below is more detailed set-up and test explanation: 1) Library project: FooLib public interface IFoo { ... }

View 9 Replies View RelatedI'm building an app where I want to architect the app layer separately from the service layer (not android services). So I'll create a service interface(the apis) and then create a class(es) that implement that service interface. Inside the android application layer, I want to code to just that service interface. I think this is similar to how the google maps apis works. the api interface and stubs are in the framework, then each device actually provides the implementation. I don't need to go that far, but I am wondering how I package this up. One, where would I put these interfaces, so I can code to them in the app layer (like Activities). Second, how do I tell Android where the implementing classes are? I'm guessing this is somewhere in the manifest? For now I think I would probably just build the service implementation with the application source code, if that's easier. Eventually I'd like to break that out and drop it in as a 3rd-party jar.

I'm working on a project with a group that is using Eclipse, but I'm using Netbeans. Up until today this wasn't an issue. When updating from the repo they have added some source code as a library under a directory called /lib-src. When I try to compile the code I get an error that it can't find certain packages... these are the packages under /lib-src.
Using NetBeans I can add the library as a folder so now the references to those packages are happy. However, I'm getting this new error when compiling:
UNEXPECTED TOP-LEVEL ERROR:
CODE:.........
I can include the build-impl.xml file if you need it, but I don't think that is main issue.
