Android :: Droid Sqllite Taking Long Time To Complete / Options For Moving To Start Of Result Set?
Nov 2, 2010
I am working on building an android app but I'm nothing that my SQL operations are taking forever to complete
I have profiled the app to narrow it down to the act of moving the Cursor to the first row of the result set for a simple select query (only returning 1 row where I'm testing it to eliminate the size of the result set as a problem.
Are there any better options for moving to the start of the result set?
edit:
some code...
this runs 3 times and i have time it to approximately 2 secs for all the rest of the code or over a minute with this in.
i have also run just the rawQuery statement with out the move to first and its takes bout 18 secs so im looking at the worst part of the code first.

My sdcard has been taking awfully long to mount to USB. It used to be almost instantaneous like your average USB thumbdrive or external hard disk. Im on a non-rooted nexus one running froyo. Any suggestions?

I recently bought a used, but in good condition Optimus V. Not a great phone, but it does what I need. However, in the past couple days I've found that when the phone does its auto-timeout, it takes up to ten seconds for it to switch back on. By that I mean that when I press the power button just to get to the passcode screen (not to turn the whole thing on), it takes much longer than it did when I first got it.
I've uninstalled recent apps, but it's done nothing. What to do?

Before I updated to android 2.2 and updated to latest Googlemaps the navigation was perfect. It calculated the route in seconds and was a joy to use. Since the updates, it is taking ages to calculate route, so long in fact that I exit the programme and start again, and then I just give up and dig out my atlas.

When you have a list activity and in onListItemClick() you need to obtain the selected item and then match it against various options, what is the efficient way to do it? switch case cannot be used since I want to match Strings. Is a very long if-else if ladder the only way to do it?
Basically the question is how to do something that normally would be done in switch statement with Strings.

I have a Service which needs to receive data from external packages. So, to locate the data providing external packages, I use activity- filter and PackageManager.queryIntentActivities function to locate the interesting packages. Now, from each such package, I need to get a ContentProvider URI. So I want to start the external Activity and the external activity will return a result to my service - something like "startActivityForResult". The problem is that there is no way to call "startActivityForResult" from a Service, only Activity can do that, and my project does not have any Activity, and probably can't show UI for the user.
The bottom line: Can anyone suggest a way to get ContentProvider URI from an external package, while my package has only a Service?

Despite similar question was asked, I have differnet situation: My app consists mostly of a background Service. I want to start external activities and get results back.I see several options:Create dummy Activity and keep reference to it for using its startActivityForResult. This consumes quite a lot of memory, as we know. Use Broadcast Intents instead of Android's results infrastructure: ask client activities to broadcast their results before closing. This kind of breaks the idea and not so performance-efficient. Use Instrumentation directly - try to copy code from startActivityForResult into my Service. Use Service interfaces - serialize and add AIDL connection to the Intent for starting an Activity. In this case Activity should call Service directly instead of providing result. The third approach feels closer to Android for me, but I'm not sure if it's possible to do - Service does not have its Instrumentation, and default implementation seems to always return null.

I have noticed this problem multiple times now with my droid. When I plug my droid in to charge at night, it appears to charge up to 100%, then stops charging and begins to lose its charge. When I wake up it is usually around 60 or 70%. I recently bought the multimedia dock to see if this would help. But with this it actually fully discharges because the clock is up on the screen.

Finally after many days of getting StackOverflowError, I've tracked down the issue and fixed it, only to find that my game's serialization takes about 5 -10 seconds on the emulator and most likely around that in the target. So far my the lifecycle of my game is as follows
onCreate - check if serialization file exists, if it does, de- serializes it. (~ 5-10 seconds) onPause - if the game is not complete, then serialize it (~ 5-10 seconds) I remember reading somewhere that another activity's onResume will NOT get called UNTIL the previous activity's onPause has ended. So I am worried that my game is delaying another activity that wants to start from doing so i.e like a phone call etc. I think speeding up the serialization is not going to be feasible, so any ideas on what I can do? Can I serialize in the onDestroy instead of the onPause? I read that the onPause is the only safest place to store the state.

Sometimes it will be 3 hours between when my email arrives in outlook on my pc and when the droid decides to pick it up (even though i press the refesh button for the email on the droid). when it does come in, it records the time the email should have come in. however, sometimes emails will come in within 1-2 minutes of when they hit my outlook box on my pc. my settings are set to recevie new email every 5 minutes.

I know a lot of people have been experiencing 4-5 hour time periods for charging the phone. If you want to cut that down to 2 hours or possibly less, just follow my fix steps!
1. Plug phone in
2. Turn Phone Off
3. Wait 5 seconds
4. Turn Phone On
Voila! But i still do the turning the phone off to get the full charge thing. Hope this helps you all!

at the moment I am thinking about a new app and need some information to decide whether to develop on Android or an alternative OS. I am particularly interested in "time to first screen", "boot-up time", "time to first Audio" and "app-start" (can be any from the android market or even one of the pre-installed ones) time? Does anyone know a source or perhaps measured those numbers?

I'm researching browsers and gathering information from the web, Google play, ac forums etc. But some "fixed" text won't come up with the option to copy when I long press. I could use some kind of web clipper, but as the research progresses I edit, put some things together to compare, edit out what isn't needed etc. Is there another way to copy?

Just got the phone and loving it so far but im having major issue's with You Tube, Most video's take about 5 mins to load in low quality and in high quality it can take upto 30 mins or more which of course by that time the phone locks and the video has to restart again.
Any suggestions as to why it takes so long? Also is there a setting for video's to automatically start in high quality? And for the phone not to lock?

I've noticed today that sending a picture messages takes a loong time on my Droid--considerably longer than on my old feature phone. Usually, it takes around 3-4 minutes. One picture took around 10 minutes to send. My apartment has bad reception, but when I sent these messages I had 3g and 3 reception bars. Is this normal?

My Droid Eris will charge from about 20% to 100% in a matter of 1-3 hours- it's always quite fast! Last night, my phone was at 20% when I went to sleep at about 12am and when I woke up at 6am it was only at 40%. The phone felt very hot. I took it off the charger and put it in another plug. It is now 4pm and the phone is only at 80% and at times feels hot. I checked out the cord and there are no lesions or breaks or any visible problems w/ the cord. I'm not sure what's going on- any thoughts? I'm going to take it to the VZW store to obtain an understanding. It's only been 3-4 months that I obtained the phone.

This has been an issue since the first day after I installed all my apps via appbrain (roughly 300). It takes ~36 seconds for it to open. I am starting to think I am the only one experiencing this. Does anyone have any ideas?
