HTC Magic :: Memory Leak - Phone Extremely Slow
Aug 8, 2010
I don't know if it's just me, but my HTC Magic becomes very laggy after few minutes of use. Cleaning the Market and Navigator's cache and stopping all background tasks with TaskPanel Lite helps, but then after few minutes of use it becomes extremely laggy again. Don't know what to do.
Note: When I clear all the background tasks and cache, TaskPanel indicates that the phone available memory is from 20 -> 24mb (seems to be to few) but after some minutes of use it goes to 3 -> 5 mb of available memory.

Has anyone downloaded the swype and seem like your phone runs extremely slow when it is running. When i have the swype app running then my phone is very slow, meaning when i just hit the home bottom takes five seconds to get there with all icons showing. I return to using the stock keyboard and the lag is gone. Anyone else getting this?

This is my first Android phone. I actually switched from Verizon to get it (something I never thought I'd do). So far it is absolutely awesome! Something that could make it more awesome, however, is to load it up with music and also get the test videos and pics I took off the phone to view on my PC.
That's where the problem lies. When I plug the phone into my PC (Win 7x64) and put the phone in disk mode it pops up and I can see everything that's on the phone. First I tried copying some music. It started copying at an abysmal 300-600 KB/s. It was going to take two hours to complete. I canceled it which subsequently froze Windows Explorer until I unplugged the phone from the USB port.
Next, I tried to copy the 40 MB video I took earlier. As soon as I click on the video (just select it, not open it) Explorer stops responding until I unplug the phone.
This doesn't make any sense. I realize I can remove the SD card and stick it in a card reader but that is a huge inconvenience since it is under the battery. Has anyone else had trouble with this?
I have tried three different PC's and multiple USB ports on each.

There appears to be a leak when using PhoneStateListeners. The following code simply reigsters in onResume and unregisters in onPause a PhoneStateListener. Repeatedly launch then press BACK (so the app is finished & onDestory is called before the next launch) and the number of activities reported by meminfo will equal the number of launches. For instance, here is the output I get after launching (and finishing) 11 times in sequence:
dumpsys meminfo com.example.leak Currently running services: meminfo

Without the PhoneStateListener, the number of activities is always 1 no matter how many times the app is launched & finished. So, am I doing anything wrong here? Or is this a bug in the TelephonyManager?
Here's the code package com.example.leak;
import android.app.Activity; import android.content.Context; import android.os.Bundle; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.util.Log;
public class LeakExample extends Activity {
private class MyPhoneStateListener extends PhoneStateListener {
@Override public void onCallStateChanged(int state, String incomingNumber) {
if ((state == TelephonyManager.CALL_STATE_RINGING)
|| (state == TelephonyManager.CALL_STATE_OFFHOOK)) {
LeakExample.this.finish();
} } }
MyPhoneStateListener phone_listener = new MyPhoneStateListener();
TelephonyManager telMgr ;
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
telMgr = (TelephonyManager) getSystemService (Context.TELEPHONY_SERVICE);
} @Override protected void onPause() { super.onPause();
telMgr.listen(phone_listener, PhoneStateListener.LISTEN_NONE);
} @Override protected void onResume() { super.onResume();
telMgr.listen(phone_listener, PhoneStateListener.LISTEN_CALL_STATE);
} @Override protected void onDestroy() { super.onDestroy();
Log.v("LEAK EXAMPLE", "onDestory");
}

I've got the following code:
BufferedInputStream stream = new BufferedInputStream(new URL("my url that points to a binary file").openStream(), 1024 * 1024); BufferedOutputStream fos = new BufferedOutputStream(new FileOutputStream(downloadFile)); byte buf[] = new byte[1024 * 1024]; int numBytesRead; do { numBytesRead = stream.read(buf); if (numBytesRead > 0) { fos.write(buf, 0, numBytesRead); } } while (numBytesRead > 0);

Lately, my browser seems to perform very slow: it loads pages extremely slow, and it reacts real slow - sometimes i need to wait around 10 seconds for the menu to popup, after pressing the menu key. i have galaxo 1.1. i just compared my galaxo 1.1 (on II5) to a friend's samsung galaxy with his unchanged firmware and rom (dont remember which version, but older than mine 4 sure). his browser performs much better, and the way i remember mine used to perform. i cleared the cache, reset to default, nothing seems to work.
even tried dolphin, no use...

I have noticed that if I ever turn my captivate off and then reboot it; it will take anywhere from 3-5 minutes for the Captivate to fully boot and become usable. Prior to then it is unbelievably laggy and if I even try to dial out it freezes.
I moved my 4gb of music from the internal SD card to the external SD card thinking that may make a difference but that did not solve the problem.

So 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).

I updated to froyo with the manual link from android central. When ever I view flash video's the audio sounds like it's been slowed down 10x. The videos run at normal speeds but the audio speed is ridiculously slow and deep sounding.

I successfully rooted my phone with Speedrabbit 1.7 (in like 5 minutes) then I did Recovery (which took hours cause I couldn't get it to load) and now I have removed a few of the unwanted apps Sweet right? Well, not so sweet, everything is moving extremely slow and there is an even bigger lag than before! Now this was happening before I removed apps so I know I didn't mess anything up there. I thought maybe removing them would perhaps speed things up but it didn't. Am I missing something? I AM running GDE, should I delete that? Just wandering what to do next to see my Moment have that WOW factor that everyone seems to say comes with root...

I am having problem with performance of SQLite database in Android application in Samsung Galaxy GT-I9000 device. The database contains 10 tables with 3 - 8 columns each.
As soon as a database file gains about 400 KB update/instert queries need much more time to execute - 2 seconds! In comparision to other devices (HTC Magic, HTC Desire) update/insert queries take about 40 msec !
The database file is located in application data directory. Moving database file to sd card increases the speed significantly.
Periodic ANALYZE and VACUUM commands do not affect the speed. As well as PRAGMA cache_size command.
Do you have any ideas how to improve the performance? for keeping the database in sd card or splitting the database into many files containing one table each.

I am finding that file operations are extremely slow on emulator. The same operation which takes less than a few seconds in a real device, takes minutes on an emulator. I am using a ubuntu linux machine with 2.4Ghz CPU, 2 GB Ram. I would really appreciate any help in resolving this. I am totally stuck due to this.

I've been getting this error near constantly the past day whenever I hit the Home button, and when the ui is working it's extremely slow to switch between screens. I can get the error near 100% of the time by opening an applicatio, then hitting the Home button. Then HTC Sense closes, sits at "loading" for a bit, then the phone is back to normal, albeit slow, till the next time I hit Home.
I had been running a live wallpaper of the Earth rotating in the background, and notice it rotates fine for about 3 seconds, pauses, then starts again, so something is eating up the processor I'd think?
I've uninstalled all recently installed applications. Stopped the live wallpaper. Stopped Locale. Stopped background sync, then turned it back on. Installed a task killer to see if there's a common element (none). Tried leaving the battery out for a minute.

I am about to get my first Android phone. It is a Motorola Flipside (I am on a budget and I need a physical keyboard; hopefully, if you didn't hate me for posting a new thread you will not hate me for buying a Flipside). The phone comes with Eclair, but can be upgraded to Froyo. When I do this, I know that I will have less than 100MB of free space (could be as little as 60MB) on the internal hard drive, but I am not sure how much less, and I don't want to mess around with moving too much bloatware or rooting. In order to get the apps that I have preselected to all fit, I'm going to need to get them in a certain order. I should get the ones that I can move to SD first, and then get the ones that are not able to be moved.
I have heard that App 2 SD is a good program, although Froyo can probably do it on its own. Do I need App 2 SD?
I am wondering which of the following large-ish apps can be moved so that I don't need to install apps only to be forced to delete them because they cannot be moved:
1. Battleheart
2. Battleloot
3. Modern Conflict
4. Plague, Inc.

This is my first post on the androidforums. I usually just read what other people wrote, but I can't seem to find a related post for my current problem.I date someone overseas in S. Korea, and since there's no way to send text msgs in Korean from here, I talk to her using activesync with a gmail account. She can check emails on her phone from Korea, and my phone sends me notification everytime I get an email from her. Basically it's same as texting except it allows me to type in Korean and doesn't cost a dime.For the reasons mentioned above, saving battery life isn't much of an option for me. I need to have activesync or gmail push running instantly. I tried using "check email every 5 minutes", but just imagine having to stay idle for 5 minutes everytime you text with your friends.
As of today, gmail push on android seems to work with 5 - 30 minutes delay (or manual refresh). However, Exchange Activesync will not even allow me to sync gmail (Different errors every time even though I'm putting the same information; gmail address,m.google.com as server address, username & password). I thought activesync just allows me to use "gmail push" on HTC mail app, so I don't quite understand why gmail app works (despite the lag), but activesync won't even let me sync my mail. Activesync last worked on 06/17/2010.Also, gmail push works with no lag when I'm on wifi. Is this normal?I'm starting to think there's a problem with the Sprint network or my phone. Gmail push also works instantly if my 3G bar is white. If it's greyed out, no emails come until the 3G bar turns white. Now I have to turn on AIM or MSN messenger to keep the data flowing and manually keep the 3G bar white. Then gmail push comes instantly. It's pretty ridiculous because the battery then lasts about 2-4 hours.

Does anyone else have problems with the download of packages in the Android SDK? I can download the SDK with around 300 kB/sec, but downloading the packages inside the SDK reaches only around 5 kB/sec and it tells me something like "215 minutes left". I tried it a couple of times the last days but it didn't get better. From the developer site (http://developer.android.com/sdk/adding- components.html): "Adding and updating components in your Android SDK is fast and easy". Yes, it's very easy, but I liked the old all-in-one SDKs which came to me in a couple of minutes

If I create and release multiple AudioTrack objects, the GREF count continually increases which eventually causes an application crash. Even with a forced garbage collection, I end up with the same high GREF count at the end of the loop.In my application, I continuously create AudioTracks from variable lenght buffers.I guess I can try and use a fixed size pool of AudioTracks each with a buffer large enough to fit my longest sound, and try and reuse them.Is there a better/correct way to completely clear resources used by an AudioTrack?

I use advanced task killer to keep things under control, and handcent in favor of the stock msg app. I notice that I have upwards of 80mb free memory after killing tasks after a reboot. Over the course of the day, with only my ignored apps running, that number shrinks to 48-50mb. Does that indicate a leak somewhere?

I have been banging away at this one for weeks and I feel like I have exhausted my research capabilities. I am hoping that someone will see my error in the code posted below. The code is completely functional doing everything I need, but there is a major memory leak. When I try to track memory in the DDMS, the VM Heap tells me that my object count is relatively stable and the used memory is also relatively stable (it comes back down to a similar value after each GC after panning).
When I look at the memory pie chart, the free memory loses over 1meg of capacity with each map pan (overlay reload) and the Unknown memory grows. I have not found anything with the allocation tracker. Functional Summary: I load overlays onto a map based on data I get from polling my server. When I pan the map far enough I clear the overlays and load new ones.
MapFrontEnd.java (snippets): //header info private List<Overlay> overlays;
//in onCreate overlays = mapView.getOverlays();
// here I attempt to fully clean up my old Overlays for (Overlay i : overlays) {
if (i instanceof ParcelOverlay) ((ParcelOverlay) i).cleanUp(); }

In my app, I'm fetching data via HTTP and use the response string to create an ArrayList of objects. So what I'm doing once I get the response is:
String[] fields = response.split("<field>");
and use the field[] values like this:
ArrayList<Movie> movies = new ArrayList<Movie>(); for (int row = 1; row < fields.length; row += 9) { movies.add(new Movie(fields[row], fields[row + 1], ..., fields[row + 8]);
}

I have an application that uses a Service and some list activities. When the activities are opened, I can see the heap usage increase in DDMS. When the activities are closed, the heap usage decreases slightly. The service is still running in the background at this point. If the activity is started again by re-running the application and then closed, the heap usage increases again then decreases, but never returns to the original level before the activity was first opened. If it repeatedly (10-15 times) open the activity then close the activity, the heap size (both MB and # Objects) balloons!
I'd expect ListActivity's onDestroy to take care of itself when it gets destroyed. What am I missing with this? Am I using ListActivity incorrectly?
If I examine the heap using MAT, I see 10-15 ListView objects. Unfortunately, I've not got much experience with MAT, but I think it means that the instances are still hanging around rather than being garbage collected. Can anyone explain what's going on?
A test app similar to my real code is below. Create a new android application, add this to the manifest:

When I first boot up the phone and check the memory (after shutting down all the apps I don't want running) I notice my phone has about 220-250 MB free after leaving the phone on for about 2-3 hours, with no activity on my part, that number gets smaller and smaller. I just rebooted my phone again because it was down to 125 MB free with no applications running.
Also, "Android System" is consuming 65% of my battery life. I realize that number is inaccurate after a fresh reboot so I played with the phone for a good 4 hours running apps and such, so that I could get a good test of how much the OS is eating up in comparison to other apps. 65% is a bit much no?

I am experiencing a memory / resource leak on a T-Mobile G1 device with my application. I installed the "Task Manager" application from Android market and my memory usage is not monotonically increasing. It stays relatively flat over time. Furthermore, none of the other processes are chewing up tons of memory either (really, I can get into this state with just my app running). I am not experiencing this problem on any of the other Android phones (including Eris, Hero, and Droid).
The interesting thing is that if I kill my application, the phone is *still* very slow and sluggish. The only thing that seems to be able to get me out of this situation is a battery pull. If I run my application for about 3 hours, the phone starts to become very sluggish. Even simple operations like hitting the "home" button take many seconds. I'm not sure what to do at this point and am wondering where I can go from here.

In my app activity A creates activity B, however when the back key is pressed it goes back to activity A. This is a simplified version of my application. I would expect memory to be reclaimed when going back to Activity A. Going to activity B allocates more memory. I am using dumpsys meminfo to get the allocated kbs. How can I easily tell what memory is creeping? I do not keep any references to activity B. I know about the ddms allocation tracker, but wondering if there is a more better tool to figure this out.

I'm parsing a document with large text field. In my characters section I am using StringBuilder
currentStory.append(ch, start, length);
then in my endElement i'm assigning it to the appropriate field on my object.
if (name.equals(tagDesc)) { inDesc = false;
if (currentItem != null ) { currentItem.setSummaryText(currentStory.toString());
} currentStory.setLength(0);
} setSummary is public void setSummaryText(String text) { Story = text;
}
And I am running out of memory. If I change setSummaryText to something completely weird like this:
public void setSummaryText(String text) { char[] local = text.toString(
) Story = new String(local);
}
I am fine. I just cant figure out where I am holding that reference?
Story is a member var of this object initialized with "";
Note - assigning to local String variable instead of char[] - fails as well.
