I am busy writing an app and I have noticed that it sometimes crashes, and when it does and I get back to my computer then I only have the stack trace.
Is there a way for me to take a memory dump of the app at crash time?

I've been trying to diagnose a memory leak in an Android application I'm writing. I got a heap dump loaded into Eclipse, but the results I'm seeing are very curious. There are some 20,000 instances of an exception (specifically, LDAPException from the UnboundID LDAP library) in the heap with no inbound references.
That is, they show up at the root of the dominator tree. The OQL SELECT objects e FROM com.unboundid.ldap.sdk.LDAPException e WHERE (inbounds(e).length = 0) returns over 20,000 results, totalling to nearly all of the heap. And yet, the GC runs before the heap dump and I can see that it's running in the console, repeatedly, during the execution of the leaky code. If these instances have no inbound refs, what could be keeping them alive?
I also tried doing a "shortest paths to GC" query. It shows one LDAPConnectionReader row retaining 2 instances, and ~20k LDAPException @ <addr> unknown rows with various hex addresses.
Update: I haven't had time to further diagnose this since posting it, and the bounty I posted is ending before I likely will. I'm awarding it as best I can now, lest the points go to waste. Thanks to everyone who looked into this! I will come back later and update again with the results of further diagnosis, when life is a little less hectic.
I bought iball andi 5li android smart phone a few days back. The configuration of the phone is:
512mb ram
4gb internal
1.2ghz cortex a9 processor
android 4.1.2
Although my device runs almost every app out there (including temple run, subway surfers etc.) but occasionally im facing problems.
Problem occurs after 3-4 days of restarting the phone. When i restart and check the ram usage it says 350 mb (approx) as used and 150mb(approx) as free ram every app runs smoothly but as days pass by gradually the free ram starts decreasing down to 30 mb where all the apps (games and browsers) start crashing with a low memory message. then the conditions get worse after approx 2 hrs free ram is now 0.0 bytes and even the launcher,settings etc crash with a low memory message. The only solution out is to restart the phone.
[used androids before and is quite aware of closing or killing apps but none is working]
Already Tried:
# removing apps from recent list
# stopping apps from Setting>apps>running apps & cached apps as well
# restoring to factory defaults
# used ram freeing apps (no change on ram)
I'm trying to get a heap dump from ddms in Eclipse, but it gives me the following error:
"Unable to create HPROF file for application 'space.shhh'. Check logcat for more information."
And here is the logcat output: D/ddm-heap(19153): Heap dump: file='/sdcard/com.bunnies.Shhh.hprof' E/dalvikvm(19153): hprof: can't open /sdcard/com.bunnies.Shhh.hprof- hptemp: Perm ission denied.
I've tried this on an actual device (HTC Desire w/ 2.1 Eclair) and an emulator (Donut). Both gave exactly the same result as above. Also, I do have the WRITE_EXTERNAL_STORAGE permission in the manifest.
I'm having trouble analyzing a hprof dum using the Memory Analyzer.. Anyone have any ideas? Here is the error message I get. I just used the "Dump HPROF file" button, and picked it up from the sdcard and opened it with MAT...
View 6 Replies View RelatedIn my application , i have an option to capture the hprof dump. I used
android.os.Debug.dumpHprofData (String fileName)
Initially i though the hprof data generated by the method above is for the entire device , which is not so . The hprof data generated is only for my process.
Now i am trying to generate hprof data for other process as well. I need to get the Hprof dump for all the running processes from application code.
from adb shell i tried "kill -10 <pid>" , This command will generate the hprof file for the corresponding process in the data/misc folder.
Now the problem is this command is working perfectly from the adb shell prompt , but i am not able to embed the command to mycode.
My code is like
Runtime.getRuntime().exec("chmod 777 /data/misc") Runtime.getRunTime().exec("kill -10 <pid>")
No exceptions are thrown , but somehow it is not working. The same code above is capturing Hprof dump for my process, when i give my process ID.
I tried with "android.os.Process.sendSignal (int pid, android.os.Process.SIGNAL_USR1) ;" also.Getting the same problem.It is capturing Hprof dump for my process. For other processes it is not working.
Do we need to have any special permission to kill other process from our process ? Or is it a built issue ? can you please suggest some possible way to get Hprof dump for other processes from application code?.

Is there any documentation describing the various sections of "dump device state" output from DDMS?
View 3 Replies View RelatedHere,http://android.git.kernel.org/?p=platform/ dalvik.git;a=blob_plain;f=docs/heap-profiling.html;hb=HEAD is a description about Dalvik Heap Profiling.
In "Android 1.6 ("Donut")" section, it says "Select your application and click the "dump HPROF file" button. ". I can find that button in DDMS.
I found there were three items in Device menu: 1.dump device state 2.dump app state(always disabed) 3.dump radio state
Is "dump app state" button the "dump HPROF file" button?
We have a service that seem to get deadlocked very occasionally in the field. It's not possible to hook up to a debugger. We can detect the deadlock situation programmatically. Is it possible to do this from within Java code?
if (ohIamDeadlocked()) { Thread.something.dumpStacksOfAllThreads(); }
If this is not possible, is there an adb command that could do it? I tried "adb dumpsys" but it doesn't print any stack information.
Is there way to dump the current screen to a bitmap in Android?
And what about dump screen of other applications? For example, running a service background, the foreground app could send an intent to start the service, and capture the current screen and save as a bitmap.
I am preparing a new update of my application, in this version I need to insert lot of new rows (200) in my db.
Because I don't want to programatically add 200 insert code line for each row, I would like to know what is the best method to accomplish it just with a call to the file and dumping it into my db.
I need a library in java that can take HTML content and generate text in the same format that is generated by the Linux lynx program.
That's it. Reasons below if you care.
I need to expose data provided by 3rd party servers to end users on Android. Data format is ancient, in badly formatted HTML, so much that I've tried reading it using java and it fails occasionally (unacceptable). It is also growing every month (preinstall ruled out) and I can't convince them to change to "modern" stuff (life would be great in XML etc.).
Shortest route: I wrote a class to use the W3 html2txt service online (google search it). It worked fine on the app until I got complains and noticed that the W3 service fails occasionally. It's not that big of a deal, but the black box logic expects the output to be in this "lynx like" text format.
So I would like a library to do the conversion (HTML->TXT) in "lynx style" inside the app and avoid the outages in the W3 service. And besides, the lynx output the probably the best I've seen, the most organized and neat.

Seems that what I am about to describe has plagued Droid Incredible users (post from another Android forum). Hoping someone using an Evo on Sprint can share some insight and/or solutions to the issue.
At least twice in the past couple months, all of my text messages (several thousand within dozens of conversation threads) have suddenly disappeared without warning. It basically happens like this: I check or send some texts, check something else on my phone like my email or calender or other routine function, then go back within moments to check or send another text and just like that, my entire text message history is EMPTY. Talk about frustrating!
I have doubled checked my settings and have nothing set that would cause older messages to be purged. Anyone know what may cause this and how to prevent it from happening again? BTW, I also had all my favs as identified in my favs widget totally disappear once (had to re-select each one again). Not sure if this is related, but I thought I mention it.
I downloaded GT Racing Motor Academy and want to download it, but face the problem of not having enough space. I have a 32gb external SD card and moved the app itself to the SD card but want all the 650mb of game data to download to it.

Since I'm still waiting on the Update myself, I've had a brief chat with my Source at Samsung & he confirmed there isn't nothing life chaning in the kernel regarding problems. All fixes was addressed mainly to the OS it's self.

View 2 Replies View RelatedMy application is designed to support both portrait and landscape orientations. Using my HTC IO device, it survives 12 orientation changes before throwing an out of memory exception while inflating my activity.When I follow the recommended procedure of using DDMS to first force a GC and then write a heap dump, and then load it into the Eclipse Memory Analyzer, there is only one retained instance of my application, as there should be. None of the other retained objects are obvious offenders. Just for yuks, I reran the test, and did everything the same way except I didn't force a GC. In this case I see 13 instances of my application, which is more consistent with throwing an OOM exception. Is this telling me something useful? If forcing a GC with DDMS reclaims the memory used by now-defunct instances of my activity, I would have thought the VM would have garbage collected some, if not all of these defunct activities automatically. Do I need to request GC at the very beginning of my activity lifecycle to make sure?
