How we can save a large data (~ 30-50 MB) on our device?

Nice day.

Currentlry, I'm working on an application that loads several types of data (text, pdf, audio & video) with a large dispersion in size and writes it to the memory. Approaches are used for this is is a heritage of antiquity: works correctly, but maintained it's a hell. So I want to rewrite save the game and think how I can do.

We can not save 30 MB on the piece, are we not?

We can record data as thousands in the persistent store, but with objects should use ObjectGroup. Right?

And as a case, we can 'just' serialize our data in memory. But I want to avoid this approach, because it can raise a lot of problems when I try to size calculated data in memory, moved, copy, play, or compare these array of bytes.

What is the best way? Any help wiil be appreciated.

p. s.

I should kept version 4 and more.

What do you mean by internal memory?

Some phones are able to map their flash to look like an SD card.  But memory, the user has specified how much has been mapped in fact in this way.  I think that the default is a small amount.  And it has reduced the other available memory on the device.

BTW, I was wrong to say that all phones post OS 4.2 supported SD Card.  In fact, mostly done but not all.  More particularly the 8700 has no (I used to love my 8700)

In any case, here's specifications for phones that run the 4.0 OS 4.5 OS.  :

Look at the memory.  You can't wait even a Curve 8300 to deal with 50 MB stored in its flash.

Until you get to the devices OS 4.6 supported, I think not that there is enough memory on board to support your requirement in the flash store.  And of course all of these devices have slots for cards.

So I always suspect you are wasting your time trying to do.

    Hello

    Start Windows Explorer, and then see if there is a drive letter assigned for access to the
    drive. If this is not the case, check if the disc is shown in disk management.

    1. Open Computer Management by clicking on the button start , by clicking on Control Panel, system and security, clicking Administrative Tools and then double-click computer management. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    2. In the left pane, under storage, click Disk Management.

    If there has made a right click option - assign a drive letter for you can use Windows
    Explorer to copy files.

  • I want out emails in folders of ordinary files, but when I drag-and-drop, the "modification date" gets changed. How I can still see the date?

    To archive my e-mail files until I decided to switch to Thunderbird, I create regular folders in windows and drag and drop emails to outlook express in the appropriate folders. The "update" column displays the original date of the email... which is what I want to do with Thunderbird. In my view, that he treats it as a new file created today... that is not good for my archiving system of these professional work files that I need to find often in approximate date.

    I understand the forum that it is by default in Thunderbird. There is an add-on that can do what I'm doing?

    Thank you in advance,
    Netwon

    I think the reason what OE is the original date because each message is stored in a single file, while TB stores all messages in a folder in a file, an mbox file. Thus, when you save a message as a single eml file, its 'modification date' corresponds to the eml file date was written in the mbox file.

    You can find the ImportExportTools add-on useful because it allows you to add the date of the e-mail eml file name when enamel is exported ("Save selected messages" of the message right-click menu).

    You can run virtually any code AS3 on MobilDevices. In others, you can run perfectly as3Crypto library and encrypt all the data you want.

  • How can I save machine vision data calculated?

    Hello everyone,

    I developed a machine vision vbai file to detect the edge of a droplet and calculate the radius of the drop. However, I would like to save the data of droplets of RADIUS in a file so that I can follow the distributions of droplets at the time RADIUS and see it in excel for example.

    However, in the range of functions of industrial vision I see not all save data option and so I transferred the code in a labview VI hoping to get more options. When I opened this VI, I can't really find out where my calculated data are, and I can't also manage store data anyway.

    I'll post the Labview VI and VBAI files and hope someone can tell me how I can save the droplet radius size because I'm kinda a noob in programming Labview.

    You not only peut lose, you go. You can not do a upgrade of
    XP to Windows 7. Although you can use a Windows 7 upgrade copy,
    Since XP, you need to do a clean install with it.

    And how I can save it without copying the data to another location. Thank you

    Copy your data to another location - to external media.

  • How can reduce iCloud mobile data consumption?

    I'm on a cellular connection and must reduce my use of data. I turned off just hard iCloud on my Mac, but when I look at turn off data of Pixelmator, Pages, Mail, etc. I am notified that I will lose all data stored on my computer. I don't want to save the data to iCloud - I manage my backups separately using the other services and practices (local external drive, USB key, safe, dropbox, etc.).

    Can I transfer my data locally so it is not removed when I change this setting? Why is Mail even store anything on iCloud when it is a local client? I don't like on the removal of files on iCloud so I don't want that they are synchronized between devices. I have two iPads as well, and between all three devices, there is a lot of data back and forth without reason. I have manually sync the iPad to the computer and back it up regularly.

    iCloud seems to be the biggest offender of data.

    Grateful for any advice.

    Looks like you store documents on iCloud drive. You can save all your data files on your computer and disable iCloud drive and other features that you do not use.

    For iCloud Mail, this is an account IMAP and must be enabled in order to use your email from apple.

    Then explain exactly what data you store in iCloud? Notes, documents, etc.

  • How can I get the data view to display the same amount of time I save?

    I use the Sound and Vibration Measurement Suite.  In the data view, I display a graph of time, the power spectrum, the Color Map and the waterfall.  I am also showing strength in numbers group for several bands and doing cutting-edge research.  I record 100 ms of the transient wave.  In the data view, why the temporal plots show several seconds of data?  What determines how much time will appear in the data view?  More important, the power spectrum reflects the power for the entire of several seconds of data displayed?  Same question for power in the values of band and cutting-edge research.  I want to just this data displayed for 100 ms of the wave that I record.  So, how can I get the data displayed (waveforms) and power numbers come only 100 ms of the recorded wave?

    Finally, what is the best way to make account concisely the recorded data?  By slide numbers on the Documentation tab is not concise, because it comes with graphics, etc..  I tried save as ASCII/LVM, but I get a bunch of stuff intermiated I don't care.  Help?

    Hi TimRsandiego,

    SignalExpress is programmed to display graphs with default scales based on the type of action, it's reading. These scales and settings can be changed by right-clicking on the graph, and then select Properties.

    If you are interested to learn more about how to use SignalExpress, I would recommend checking out some demonstrations/tutorials on NI.com. You can find some of these demos at the following location:

  • How can I get the data from a range of AutoFilter in Excel?

    I have a spreadsheet with a large number of lines (5000) where I want to extract data.  I have opened the workbook successfully, configure an automatic filter and filtered the data to select the data corresponding to the criteria using the nodes property of the ActiveX Excel object and invoke.  I now have to enter the selected data in a table for later processing, and this is where I am stuck.  Help Excel online seems to suggest the creation of a Range object by using special cells with the xlCellTypeVisible type.  If I Range.Count I get the right number of cells, but Range.Value2 produces a variant which contains only the first block of data (a beach filtered automatically seems to consist of several non continuous blocks).  Anyone know how I can read the contents of the range in an array of strings?

    Thanks in advance

    Found a calling areas of property which returns a collection of the areas of each of them continues a range object.  Simply cycled through these areas using the earlier technique, build the table I want.  See below

  • How to install the large data file?

    Anyone know how I can install large binary data to BlackBerry files during the installation of an application?

    My application needs a size of 8 MB of the data file.

    I tried to add the file in my BlackBerry project in the Eclipse environment.

    But the compiler could not generate an executable file with the following message.

    «Unrecoverable internal error: java.lang.NullPointerException.» CAP run for the project xxxx»

    So, I tested with a small binary file. This time, the compiler generated a cod file. but the javaloader to load the application with this message.

    "Error: file is not a valid Java code file.

    When I tried with a small plus, we managed to load, but I failed to run the program with that.

    "Error at startup xxx: Module 'xxx' has verification error at offset 42b 5 (codfile version 78) 3135.

    Is it possible to include large binary data files in the cod file?

    And what is the best practice to deal with such a large data files?

    I hope to get a useful answer to my question.

    Thanks in advance for your answer.

    Kim.

    I finally managed to include the large data file in library projects.

    I have divided the data file in 2 separate files and then each file added to library projects.

    Each project the library has about 4 MB of the data file.

    So I have to install 3 .cod files.

    But in any case, it works fine. And I think that there will not be any problem because I use library projects only the first time.

    Peter, thank you very much for your support...
