Is there a good way (proper way, or effective way) to debug slow running code? I have a thread which runs multiple loops and then recurses and my code is running very slow. Is there a good way to debug different loops or sections of code to find out which is running slowest?

I've got some trouble with the media backend (mostly Stagefrightplayer) in Android, and I'd like to understand why it throws the errors it does. The errors are usually device spesific, so debugging on an emulator wouldn't be sufficient.
Example:
CODE:.................
Example 2:
CODE:.............................
I've also gotten the player to bork completely and spit out a traces.txt.
Is there a way to debug what's happening, just like I debug Java code?
I am programming Android applications, and the best way here may or may not be the same as Java in general.I simply want to be able to set a debug flag that will only execute certain portions of code when it's set to true equiv to C++ setting a preprocessor #define DEBUG and using #ifdef DEBUG.Is there an accepted or best way to accomplish this in Java?
Right now I'm just going to set a variable in my Application object, but I don't imagine this is the best way.
my android application runs in debug mode only even if i click the run button of the eclipse or run it by touching on its icon on the device. what will be reason for this?? anybody has any idea about it?

View 2 Replies View RelatedTo make development easier, I want to be able to send textual commands to my android app(especially prior to having prior the UI completely fleshed out).Presumably in the emulator, but it would be great if it also worked on a device connected via USB.Of course, I could add an editText control to my app and type the commands in there, but would prefer not have deal with debug things cluttering up the UI and all the complications of that.I also would like to be able to paste text from computer clipboard, which sorta rules out EditText controls.Is there any way to do this, say via any of the android-sdk/tools/ stuff? I would implement the command processor java class/method, but need some way to be able to actually feed it a string. I suppose I could do something that talks to the emulator via the file system or something, but would prefer not have to spend a lot of time doing this if there is something already available.
View 2 Replies View RelatedWhen I debug android app, if I work with Java, I can use Log.d("TAG", "xxxx", new Throwable()) to print backtrace of Java code. This is really handy for me to find bugs. But when I work with native library (e.g. libwebcore.so), there seems no way to print backtrace in runtime. The only way to debug native code is use gdbserver.
I have a question: Is there any way to print backtrace in C/C++?
I have a activity B that is called by activity A, I want to debug the code in B. I have set the breakpoint, however the debug control never enters B.
CODE:................
When I debug in eclipse, although the class B is called from class A, the debbugger pointer never enters the new window, where I have placed a debug point in Class B. I am not able to take the pointer control to class B and stop at a specific point, which will help me verify certain variable values.
Why should the debugger don't make breakpoints stop when running an android app on Eclipse ?

View 5 Replies View RelatedJust upgraded to 3.6 after this whole Sun/Oracle JVM fix/debacle and I notices that 3.6 EE runs super, duper slow. So slow to the point that code assist is unusable. Here are some changes I made to the config to make it operate a lot better:
eclipse.ini: replace the end with this:
-Dosgi.requiredJavaVersion=1.6
-XX:MaxPermSize=512m
-Xms128m
-Xmx1024m
And turn off JAX-WS Proposals in Content Assist Window > Preferences > Java > Editor > Content Assist > Advanced. I also disabled JPA and PDE, but you might need them depending on what you're doing.
Eclipse HELIOS (3.6) Code Assist very slow?
View 5 Replies View RelatedA while back I mentioned that running the imported p2p codebase I have on the emulator (on a fairly powerful laptop with plenty of mem and a fast processor) was pretty slow. I blamed all that on the codebase and in fact I was able to profile it and make it much lighter. Well still the overall app performance is slow --- and I am finding that most apps I run on the emulator are fairly slow. Is this a common trend? I do expect emulators, who are by no means a real device, to have such processing delays but are they in general this slow? Any metrics or any other feedback from anyone that depict the factor of slowdowns you would expect on an emulator vs the real device? I know a lot of this are machine dependent as well but consider an idle powerful machine. And regarding memory - I am loading Eclipse with close to 1G to be able to run the emulator and its basic services - is that normal?
View 3 Replies View RelatedI have an Android project that I have been working on and debugging just fine for several months, but for some reason it is now consistently hanging at the "Runnning tests..." step. I have experienced intermittent hangs from the beginning, but a simple retry and/or restart of Eclipse or the emulator usually resolves it. But now I am just dead in the water.I can run my tests fine, and I can debug my actual program, but I can't debug my tests.I have tried creating a new emulator and that doesn't fix it. I also cleared all my breakpoints and that had no effect.As far as what has changed lately, the primary thing is that I upgraded to rev 7 of the SDK tools. Also, I recently did some debugging (of the program not the tests) on an actual device (not the emulator). Can't see how that would impact it but I thought I would mention it.Actually I had to set Debuggable to "true" in the app manifest to get device debugging to work. Although I have never had that set in my test project, I set it, and that also had no effect on the issue.I'm running out of ideas, and I would greatly appreciate some pointers.

View 5 Replies View RelatedSo lately my Eris has been running extremely slow. About a week ago I got a notification for "Internal memory is getting low." So after reading through several threads of the same topic and doing all the suggested actions (delete old text messages, uninstall unnecessary apps, clearing the cache for applications) my internal phone storage now says that there is 45.61 MB free. Yet, I still have not noticed any improvement in performance.
For example, I use Handcent to text message, and lately I have been unable to open it without it force closing every time. I've tried removing it as the default and using the native SMS program, but when I go to compose a new message it won't bring in any of my contacts when I go to select one. It just stays at a loading screen and then force closes. Also, it shows the phone number of an incoming text instead of the contact name as its stored in my phone book, so I pretty much have to guess who's number it is. Any thoughts on why it would do that? The dialer is just as bad, and since I don't have any of my friend's phone numbers memorized the phone is pretty much useless now and unable to perform the most basic of functions, using it to make calls.
I'm at my wit's end pretty much, the only other thing that I can think of is performing a factory reset. Does anyone have any alternative suggestions or experience as to whether a full reset actually helps?
My phone is not rooted. I know, I know. Rooting will improve performance, but it seems like a hassle to me and I'd rather not have to deal with it (at least not yet).
Anyone else noticed slow open times and navigation lag within the app since the last few updates?
