[android-beginners] Re: Directory names
Thanks Mark - I know all about the Linux file system behavior - ls vs ls -a etc. So I guess my question was answered indirectly, the emulator File Explorer does not display dotted files and it emulates an 'ls'.

[android-beginners] Re: Large jars in Android
Hey Paul, I will try increasing the -Xmx to 768 and hope it helps out. I am also looking for circular refs in the jars just in case that is the problem but I doubt I will find any. Some older postings do refer to apps that go to size up to 16MB and more so my 5MB one should not be the issue. I think the packaging of apps over 1MB gives the Android plug in a bit too much to chew ( especially if it is composed of thousands of classes) ...

[android-beginners] Re: Including libraries in project
Hi Mark, so it does seem that if the jars are not compiled under Android, the Android plug in (if the Eclipse Project Build Automatically is checked) rejects them from the apk - in other cases it does not generate the apk at all. Some of the libs I need are part of the Java's standard libs (ex. java.awt.*; does exist in Android SDK but java.awt.event.ActionEvent; does not). So I am guessing that either I should find a compatibility library written for Android for these libs or to avoid using them and use only what Android offers.

I don't doubt that it works actually and I do think it has to do with either how I configured the plug in or some other issues with Eclipse - the build path etc I know that pretty well so I don't think that's the problem. I will post a solution once I find it to help anyone else who may have the same issue. The libs dir is either in the src dir or the top level dir. The libs/ dir is supposed to be in the root of the project dir. Now, I have heard that you can have it located elsewhere when you are building with Eclipse, but I have not tried that.

And finally the .dex archive (and subsequently the .apk file) contains all the project classes but not the jars from above. So what am I missing??

And one more interesting fact - if I add the jars as External Jars using Eclipse, building the workspace takes a while, eventually it runs out of memory and it only generates the resources file (no apk and no dex).

[android-beginners] Re: Including libraries in project
Hey Mark, good points as always - There are a multitude of reasons why an existing JAR may not work on Android: -- It was compiled with Java 1.4.2 or a non-Sun/Oracle Java compiler -- It assumes certain classes exist (from, say, JavaSE) that do not ship with Android -- It uses JNI (and therefore needs to be adjusted to work with the NDK) -- It assumes certain platform binary programs exist, or exist at certain paths, which may not be the case on Android -- and so on Exactly - the jars I am importing are from Sun's famous JXTA-JXSE project that was compiled with Sun's Java 1.5+ but although it does not use JNI I have a feeling that it assumes certain classes exist ... I noticed the owners of the PeerDroid project did manage to compile the J2ME-CDC version of JXTA-JXME under the Android platform. However, what was curious there is that they also included external jars in their compilations (bcprov-1.4 etc.) that I am also try to include - I will see if I can find how they got away with that. But before I can get to the bottom of this one my first issue is what you are describing below ... Step #1: Put the JAR in libs/ I did Step #2: If using Eclipse, add it to your build path I did Step #3: Code to the JAR's API and build your APK I did Even for the case of the jars that are Android-friendly they don't get included in the apk. The libs dir is either in the src dir or the top level dir. Once I move it in the assets dir I can see it being wrapped inside the apk. So before attempt to compile the code from above I will see if I can figure this one out.

[android-beginners] I/O
Is it possible to write and read files on Android? I know it sounds a bit silly to ask this but I found out that writing a file in the same directory as where the app is executing stall my process. Where in the dir hierarch do Android apps execute and if I was to write or read a file do I need to do so in a particular directory?

I noticed that using the standard Java to create the new file stalls: File UIDfile = new File(/data/local/tmp/myUID.txt); UIDfile.createNewFile(); Is this something that should not be used in Android?

That's what I figured - thanks Mark. I think it makes more sense now.

[android-beginners] Re: I/O
Sorry for not being clear from the start Mark - my bad. When the app reaches the createNewFile() method it quits (I thought it was stalling on that method but I was wrong). I think that method is the problem in my case. I did use adb push to copy files to the emulator's filesystem so that answers that question - I could play around with that from my app and see how the file i/o works since I am new to it on the Android. How would I go about creating/finding an SD card image for the emulator?

[android-beginners] Re: I/O
Normally I don't get into this back and forth QA loop as I know very well how busy most people are and what the real purpose of the mailing lists are, so I apologize for letting it get out of hand. You are right, most likely I should be able to find a lot of these fundamental concepts either on the web site or the books and I did have good luck finding most of them. However, since I am importing a large application from an existing standard java code to Android there are cases that I am not finding whether what exists in standard java is generally accepted under Android and thus the multiple questions. I guess I am learning by brute force in this case. I do know this is a mobile platform and its capabilities and API should be honored, but I am also trying to reuse segments that can work equally well if they are imported unchanged. In any case, your point is well taken so thanks for bringing it up. To clarify my last question, by stalls or quits, I mean that I am watching the app execute in the DDMS console, and although I am catching exceptions around that particular code segment, the execution stops, no exception is thrown and nothing occurs thereafter. I am not sure if the execution of certain methods imported directly from J2SE cause the VM to have issues - I will examine it closer and see what the story is there. I will limit my questions to more substantial issues as they arise. Thanks again.

[android-beginners] Re: I/O
One last thing - extending my question from the previous email - may be this is what I should have asked to begin with and left it at that: Since I can compile my complete imported app as an Android project it makes sense that the classes and methods I used in the past (even the System.out that we already spoke off) should be operational under Android. Correct? If not, is there documentation that you may know off that rules against such methods - for example if my problem now is the File.createNewFile() and for some reason does not work well under Android, is that documented somewhere or this should not be the case and pretty much what compiles should work. I hope this makes sense. Again thanks for all the help Mark and apologies for the multiple postings.

[android-beginners] Re: I/O
I know I know - I rudely jumped into asking questions and that is a no no - you want people to help you make your context clear first and the rest will follow (to a certain reasonable extend of course ;) ) ... That's...very strange. Yes it is - but hey, I am sure what I learn from getting to the bottom of this would be something to remember for a while. I've never used createNewFile() in a decade-plus of Java development, so I can't speak specifically on it. If the method exists, there's a 99.9% chance it should work as expected. There are a few no-ops (notably in Thread for stuff that's been deprecated since the Clinton Administration), but the bigger problem tends to be things that are just flat-out missing. For those, you'll get compile errors if you're compiling from scratch, or VerifyErrors if your existing code base is in a JAR you're importing. Ha ha - yes some stuff in there are old. In any case, I appreciate the help Mark, I am finding this list and the Android platform a pleasantly refreshing environment to work in compared to the older devices I have been messing around with. I will post any good-to-know results back to the list once I have them. Demetris -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!

[android-beginners] Re: Emulator
Hi guys --- to put closure to this thread as well - I compile the changes in the Resource perspective in Eclipse, and with the emulator open I re-launch the app either in debug or standard mode and watch it in DDMS. I can see the apk file being loaded in the emulator's file system (I can see the size and it is the new one for sure), however, the changes I made do not show up in the execution panel. Are there cases when I need to shutdown the emulator and restart it? Or would the relaunching of the app ALWAYS guarantees the changes will be executed? Just making sure.
