Android :: Determine Droid Database Maximum Size And Prevent SQLiteFullException?
Sep 7, 2010
I have few queries on Android SQLiteDatabase
1.) As normally the database stored in internal memory, can we specify the path of external storage and use it in similar way ?
2.) How to determine the size of available space of database ? I used getMaximumSize() from SQLIteDatabase class but that gives me 1099511626752
Is this in bytes ? If assumed then this seems to be too large and not practical. I am using HTC G1 to test this.
3.) How can I determine the size of an entry in table ? Or do I have to pull the whole table and manually see its size. Is it same that would be in phone storage ?
4.) Can I check if any free space available before making entry in database ? I want to prevent SQLiteFullException.
I have a SQLite db that size is over 2.6 GiB. (The db contains maps.)
This db is used by RMaps app. When move the maps to some parts at maximum zoom, the app suddenly closes.
However, there is no force close message, no report button. So, I've got an idea that it is caused by reading blocks that are beyond a certain limit e.g. max(int). Since RMaps is just using simple SQL statements, I think that the problem is not in RMaps but rather in Android SQLite driver.
Is there a size limit of SQLite database on Android?
(I have Froyo on Nexus One, but I do not think that this is just a problem of Froyo.)
UPDATE: Log output:
UPDATE2: The SQLite db is stored on SD card, there is enough space.
what is the maximum size of application's database allowable in Android? In other words whats max capacity of android appl private database, as well as whats max capacity of content provider available?
What is the maximum size that android application can hold? I have one database(.sqlite extension) file with 147 mb, Is it possible to include that file in my app.?I tried to put it in my asset folder but while running it showing message like "No space left on device".
Does anyone know the aximum upload file size for Droid you tube videos on 3G? I'm going to be in an area with most likely no wifi but I'm pretty sure I should have solid EVDO and I need to upload videos, just wanted to know the maximum file size/length for youtube videos and if there's a way to bypass the limit (I really don't care if I ring up 1.5 gigs of data).
I am implementing notification handler which logs any changes in content provider and it notifies Broadcast Receiver using custom Intent on periodic basis.But problem here is from Provider to Receiver all the values passed through Bundle.
Currently I'm implementing a REST client which shall parse the XML response messages. It is intended, later, to be running on an Android device. Thus, memory and processing speed is quite an issue. However there will be only one XML response at a time so processing or holding multiple XML documents at a time is not an issue.
As fas as I understood there are three ways of parsing XML with the Android SDK:
SAX XmlPullParser DOM
Reading about these different parsing methods I got that SAX is recommended for large XML files as it won't hold the complete tree in memory like DOM.
However, I'm asking myself what is large in terms of kilobytes, megabytes, ...? Is there a practical size up to which it does not really matter whether using SAX or DOM?
I am going to install first application in my android phone, but having some doubts related to Android Memory (Maximum size of APK).
Help me know and solve the problems:
What is maximum size of the apk that can be supported by the android ? When we install any apk file in real phone, where does application installed (in SD-card or other memory) ??
I have referred this link: http://groups.google.com/group/android-developers/browse_thread/thread/7965885da4d1a03a and also searched lot.
I came Across the search on the web that many people are facing the same issue What is the maximum size of Application supported by Android. I think this question also help to the people who are connected with Android application programming and development.
This time i am having 58Mb application from that 52.5MB Images and it runs on the my HTC Hero mobile but On Emulator, it shows an error:
Failed to upload my_application.apk on device 'emulator-5554' java.io.IOException: Unable to upload file: No space left on device Launch canceled!
Way to store images inside the Drawable folder? is there any way to zip the images or such method?
I have an app which does a bunch of image manipulations, and those images are ideally full-screen sized. It works on a G1 (or HVGA emulator), but runs out of memory on a WVGA emulator instance, because full-screen images use twice as many pixels. Fine, I can work around it by manipulating smaller images, then scaling up to WVGA at the end. There's some loss of image quality, but this is unavoidable on a WVGA device with a 16MB heap limit, so I'll live with that.
When a real WVGA device hits the streets in the next couple of months, though, it's likely to have more than 16MB heap per app, for just this kind of reason. So for best image quality, I'd like my app to adapt to this situation, and use full-screen-sized images on such a device. IOW, I'd like to implement a heuristic which sets the image size based on heap size.
In order to do so, however, the app needs to know what the maximum heap size is, and I haven't yet found an SDK call which will return this information. The various Debug.get* memory calls all seem to be to do with how much heap you have *allocated*, not how much you theoretically *can* allocate. I understand that this isn't necessarily a hard number, that issues like fragmentation and GC mean that you may not actually be able to allocate every last byte, but a theoretical number would still be useful.
I have 3 video files each of 70 MB in my raw folder besides other audio files of few KBs. I am getting an installation error of insufficient space on the DROID while testing my app. I tried uninstalling apps and am now left with apps that are essential to the device.
What needs to be done to resolve this issue? I also wonder what will be the app size that i am allowed to upload to the android market?
Some of you may met the same problem, I was using BitmapFactory.decodeStream, and got this exception: Code...
I know the reason is because the BitmapFactory is trying to decode an uncompressed version of a big image(in my situation, jpg). I can use BitmapFactory.Options.inSampleSize to fix it. but my question is what's the maximum size that VM would like to allocate for loading a image with BitmapFactory? so I can do some scale before it loads.
I want to do some data processing (in a thread) right after my main Activity starts. For that data processing to be started I also need to know a visible size of my main View (which is a LinearLayout currently, but whatever).I wonder how to do that. I.e. I wonder what is the entry point (callback?) I should use to be sure that my main View has been layed out, so i can use view.getWidth/getHeight? Is creating a custom View and reimplementing it's onSizeChanged() - the only way? In this case how should I properly describe it in my xml layout file? (it will contain some child views)
How can I determine/calculate the byte size of a bitmap (after decoding with BitmapFactory)? I need to know how much memory space it occupies, because I'm doing memory caching/management in my app. (file size is not enough, since these are jpg/png files).
Yesterday morning i removed some apps from my rooted 2.1. Nothing exotic, i'm not at that level of exploration, just the common ones recommended like the stock widget & apps (all 3 instances & their .odex) and the visual voice mail. later in the evening i felt the phone wasn't performing as it should. Taking an xxl image with my fav photo app vignette cause the phone to freeze & i had to remove the battery, the same happened with meebo. how can i see an apps size from the command prompt?
I have an activity which uses android:theme="@android:style/Theme.Dialog". The activity contains an ImageView which can show images of different dimensions. The ImageView should scale the Image so that it entirely fits into the window, at least on axes fits entirely and maintains the original aspect ratio. The size of the dialog should only be as large as the ImageView (plus its border width).
I tried the following but the dialog window always uses the whole available space:
what the maximum file size is I can attach to an outgoing email using Gmail? I know Gmail allows 20 megabytes, but is there a size limit I can attach from the Hero? I have had the phone tell me a file is too big to attach, but it was well under 20 megs.
I use a sqlite database in my project. The stored data in it must not be available for the user to edit. As I've read here I saw that if you have root access you can alter sqlite database. The only solution would be to encrypt database content, but this would be time consuming for device. Any solution to prevent access to database ?
I own a Nexus 5. When I record long videos, the recording always stop at 15-16 min or around 2 GByte file size? Is there any Android OS restrictions on file size or format of the internal memory or something?
I have android application and service that runs in separate process. Application and service read and write to same database (and same table). What is the best way to work with database? How to prevent locks?
