Android :: Eclipse Debug Issues While Coding Phone Applications
Sep 27, 2010
I have an application I am writing for Android that basically does a screen scrape of a large table on the web and presents it in a nicer way on the handset. Its 500k of html and takes about 20 seconds or so normally.
When I have my phone hooked up to the computer, I used to be able to just click on "Run" and my code would execute similiarly speedy, as opposed to Debug where it would take 10 minutes to complete.
Now, however, clicking "run" behaves just like debug mode.... I don't want this overhead, how do I get eclipse to stop sending my app to the debugger already? I have searched online and found a couple people with the same issue, but simply rebooting my phone doesn't fix it, and there have been no other solutions posted that I have found.
I have mostly been avoiding debugging when I can because of these two problems, so hopefully someone here has suggestions to avoid them:
1. It seems that I have to build the SDK (`make sdk`) and copy it off to a directory for Eclipse to use almost every time I want to debug. I haven't followed through the "sdk" directive, so I'm not clear on why this is necessary instead of just having Eclipse read from the source in my directory. Isn't there some way for it to do this? FYI: I have a (modified) full checkout of Donut, not just the SDK.
2. How can I debug without using Eclipse? I would really like to be able to use something like gdb/jdb.
I installed and eclipse, android sdk and tried the first "hello, android" tutorial but nothing happened on the AVD There are no compilation error, I tried to set break points in the but it does not seem like the application started running at all...
I can no longer run/debug my application in eclipse, when I attempt to I get the following error in the console:Installation error: INSTALL_PARSE_FAILED_NO_CERTIFICATES.E/PackageParser( 65): Package com.example.foo no certificates at entry assets/community_error.html; ignoring.I have not touched my android config or project configuration, and it was working fine yesterday, i'm running ubuntu/jaunty, i did a kind of security update this morning and i think it might have broken zlib or something.
I am trying to following this documentation 'http://source.android.com/using-eclipse' to debug android Launcher Activity in eclipse.
It said' You may need to open the Debug perspective (next to the "Java" perspective icon in the upper-right, click the small "Open Perspective" icon and select "Debug"). Once you do, you should see a list of threads; if you select one and break it (by clicking the "pause" icon), it should show the stack trace, source file, and line where execution is at. Breakpoints and whatnot should all work.
My question is which threads I need to select in order to debug Launcher Activity? I don't see a thread name Launcher.
I have set up a "Debug Configuration" to debug my Android project. However to get it to debug on a device (HTC Desire) I have to set the Configuration's "Target" to "Manual", there seems to be no way to set in the Debug Configuration that it should go to a selected Device.
It does work, but each debug session I have to "Manually" choose the HTC device from the dialog. Can I set it to always to go the Device?
I'm using Eclipse and have an emulator running Android 2.1 and my IntentService. I'd like to step through my onHandleIntent() overridden function. I've put in a breakpoint on the first statement of the function, which is Context context = getBaseContext();. When the intent is called the program just fails and does not go to debug view in Eclipse.
I've tried to debug the android applications on emulator and than on the device as well but all the time I get the message "Wait for debugger - waiting for the debugger to attach to the process". I really don't know how to set the environment and the application in order to run the debug.
I am using eclipse android plugins to build a project, But i am getting this error in the console window: [2010-02-03 10:31:14 - androidVNC]Error generating final archive: Debug certificate expired on 1/30/10 2:35 PM!
I uploaded my application to Market and then downloaded it to my phone. Now I'm unable to use debug keystore which is used by default by Eclipse ADT Plugin (Re-installation failed due to different application signatures) and when I'm trying to setup own keystore in Eclipse->Windows->Android->Build->CustomDebugKeystore, I'm unable to enter password or accept keystore and type password later. Is there anything I can do or only way do debug app on device is to uninstall market version and deal with default debug keystore?
This is more of an Eclipse error than an Android or Ant error. My Eclipse project won't build because when it sees the build.xml created from the Android command, it starts looking for the debug and release commands. Well, since they are dynamically generated from the <setup> task, they don't exist. So now Eclipse (Build id: 20100218-1602) locking the project from build/run based on these errors. kay.. so here is the weird part: It worked this morning. In fact it has been working for weeks with the build.xml file sitting there. All I did was edit the build.xml file in Eclipse (changed some constants). Ant thinks everything is peachy.
i install new version of eclipse and Android sdk , but when i run an android project i get this error
Could not open Selected VM debug port (8700). Make sure you do not have another instance of DDMS or of the eclipse plugin running. If it's being used by something else, choose a new port number in the preferences. ADB server didn't ACK * failed to start daemon * i try to solve the problem by following this , but i still get the same problem:
-Window -> Preferences -> Android -> DDMS -Set Base local debugger port to "8601" - Check the box that says "Use ADBHOST" and the value should be "127.0.0.1"
i am also tryng to reinstall android pluing for ecipse and even the android sdk , but i still get the same problem!
I'm currently developing a software under android and im getting quite quickly some OutOfMemoryException.... I did modified some part of my code to use more static variables instead of making new allocation with the "new" operator but is there any things else to do ? or any other tips ? Any advices would be welcome.
I wanted to check whether there is any JAVA Coding standards in Android platform for performance improvements.
For Example, like an Effective Java code in J2EE environment is to defined the number of elements in the ArrayList constructor rather leaving it blank (new ArrayList(noOfRows)) etc. I definetly suspect these performance tuning tips should be available because of the memory and resource constraints.
I have ten, possibly more, apps I'm developing that all share logic. 50-75% of the logic is the same - perfect for some time of library or code sharing. However, after reading the posts here and trying to share code in Eclipse, I'm not sure that's going to work. I tried going to project -> properties -> build path -> link source and adding the src and gen folders of the project with the shared code and then importing the classes I need. That seems to work in the IDE, but gives an error during runtime: class not found. This seems to be a common error for people attempting this.
I am slowly deciding that shared code is not the best approach in this scenario. Android doesn't seem to work well with this type of code sharing. For one thing resources are not packed in libraries, but references (R.whatever) must exist so as not to create errors. This can be designed around, but the effort and headache is probably worse than simply creating multiple copies. My experience seems typical, based on what I've read. Is it? Have you experienced success or failure with sharing code and/or custom libraries? Am I off-base in thinking that multiple code copies will be smoother sailing than fighting the shared code approach?
If I try to use my HTC Desire to test Apps I'm developing with Eclipse, then in the screen where I can choose the emulators and connected devices, it is only listed as unknown and a few question marks. I read that on Windows you need HTC Sync respectively the drivers in this program, but how can I solve this problem on Ubuntu?
I made a mistake and I still had the debug version of my app (from Eclipse) on my phone when I tried to install a signed version. The install failed, but I could no longer access the debug version in Manage Applications to un install it. I was at work and couldn't reinstall the debug version in order to uni nstall, so I did a complete factory reset of my phone (using My Backup Pro to backup stuff). Now I can install my app. However, now I notice upon reboot that my app loses all of its data from shared preferences. I'm not entirely sure that it's not a problem of mine somehow, but does anyone know why it is doing that and how I can fix it? I may have left the debug gable. true on in the version I'm trying to test. Would that cause this problem?
