I have downloaded a file from HttpConnection using the FileOutputStream in android and now its being written in phone's internal memory on path as I found it in File Explorer
/data/data/com.example.packagename/files/123.ics
Now, I want to open & read the file content from phone's internal memory to UI. I tried to do it by using the FileInputStream, I have given just filename with extension to open it but I am not sure how to mention the file path for file in internal memory, as it forces the application to close.
I have a galaxy portal 2.2. The internal memory was getting full so I installed a new 4gb sd card thinking it would give me more storage, this is ok for music photos etc. but seems apps are stored on phone memory, when I want to get new apps I have to remove some old ones , I've looked on market for an apps to keep apps on sd card, but can't find anything.

View 29 Replies View RelatedThe HTC Desire has limited memory of around 570Mb RAM and 512Mb ROM. The MicroSD card can hold up to 32Gb. So, why can't HTC allow apps be stored in MicroSD card? If HTC/Google's concerned about piracy issues, i.e. copies of apps from microSD card to another microSD card, etc. There is one way round to this problem: They could have installed some kind of unique crypto-key within the Desire's ROM, and any apps saved to the microSD card are automatically encrypted on-the-fly with this crypto-key.
When apps are accessed, it is decrypted on-the-fly, too. In other words, apps will ONLY work with THAT phone it shares the SAME crypto-key. Putting a microSD card containing apps into another Android phone will not work, thus solving the piracy issue. Therefore, a message to HTC: Please allow apps to microSD card (as much as 32Gb card) and BEAT iPhone/Nokia N900 at their game!
I installed an SD card but it appears all my pics and music are being stored on the internal memory. What do I need to do to fix this problem?

View 1 Replies View RelatedI am currently making an app which works with images. I need to implement functionality where the user picks a file stored on the SD card. Once they pick the picture (using the Android gallery), the the file-location of the image will be sent to another Activity, where other work will be done upon it. I have seen similar posts here on SD, but none to answer my question specifically. Basically this is the code I am doing when the user clicks the "Load a Picture" button:
// Create a new Intent to open the picture selector:
Intent loadPicture = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
// To start it, run the startActivityForResult() method:
startActivityForResult(loadPicture, SELECT_IMAGE);
From that code, I then have a onActivityResult() method to listen to the call-back:
// If the user tried to select an image: if(requestCode == SELECT_IMAGE) {
// Check if the user actually selected an image: if(resultCode == Activity.RESULT_OK) {
// This gets the URI of the image the user selected: Uri selectedImage = data.getData();
// Create a new Intent to send to the next Activity:
Intent i = new Intent(currentActivty.this, nextActivity.class);
// - Problem Area -
// I would like to send the filename to the Intent object, and send it over.
// However, the selectedImage.toString() method will return a
// "content://" string instead of a file location. How do I get a file
// location from that URI object? i.putExtra("PICTURE_LOCATION", selectedImage.toString());
// Start the activity outlined with the Intent above: startActivity(i);
As the code above states, the uri.toString() will return a content:// string instead of the file location of the selected picture. How do I obtain the file location?
Another possible solution is to send over the content:// string and convert that into a Bitmap (which is what happens in the next Activity). However, I don't know how to do that.
Here is what I am trying to do:
- have a database that contains a word, and the name of an image file associated with that word.
- the words from the database will be displayed in a listview
- when the word is selected, a new activity will start displaying the word and the image in an image view.
Would it be best to store the terms in an array and have the list view populate from this array and then pull from the database onitemclick? Or can the list view be populated with the terms from the database?
Will android be able to display the image if the name of the file is stored in the db?
How I copy a image to internal memory and recover after that?
View 2 Replies View RelatedWhat I'm trying to do is this: I want my application to download an image from the Internet and save it to the phone's internal memory in a location that is private to the application. If there is no image available for the list item (i.e. it can't be found on the Internet), I want a default placeholder image to display. This is the image that I have defined in my list_item_row.xml file as the default.
In my ListActivity file, I am calling an instance of a CustomCursorAdapter class I have written. It is in CustomCursorAdapter where I am iterating through all the list items and defining what content needs to be mapped to the views, including the image file by trying to read it from internal memory.
I've seen several questions on this subject, but the examples either are specific to external phone memory (e.g. SDCard), involve saving strings instead of images, or involve using Bitmap.CompressFormat to reduce the resolution of the file (which is unnecessary in my case, as these images will be small thumbnails of already-small resolution). Trying to piece together code from each example has been difficult, hence my asking about my specific example.
At the moment, I believe I've written valid code, but no image is displaying for my list items, including the default placeholder image. I don't know if the problem is being caused by invalid download/save code, or invalid read code - it doesn't help that I don't know how to check internal memory to see if the image exists.Anyways, here's my code...
Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?
Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.

View 11 Replies View RelatedI have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.

I developed a cramfs rom for the np7 after user dochoppy found root for the nextbook premium 7 tablet, but he then converted to ext3 which because its packed with features will be more popular. So I am trying to edit his ext3 rom in Ubuntu 11.10 and here is what I do:
1. Copy and paste system.img to desktop
2. Create a folder called system on desktop
3. In command prompt:
cd ~/Desktop
Sudo mount -t ext3 -o loop system.img system
(Asks for pw)
4. Doc said something about only being able to edit as root, so after some Googling I find out how to create a program that grants root.
5. (Open "run as" program) then I type "nautilus /home"
(Asks for pw)
6. Navigate to mounted system and I have read/write privileges (but only in this window)
7. View the system mount properties, and it says I have 14.2 mb free space on device
8. Delete files throughout the system folder to make room (but when I refresh properties, free space increase doesn't show)
9. Try to add my own files after deleting some others, ans rather than using the increased space, it just fills the fourteen megs before telling me "device is out of memory "
why is the system not physically making the proper system increase and decreases.
A long time ago I had edited a file that is read on boot, in that file is written which one of the two 'partition' has to be mounted as what.
Basically, my 32GB microsd is seen as the internal memory of the device (which would be 12 GB), and the other one as micro sd. The result is that most application would go to the microsd by default, using thus 32GB for apps instead of 12GB.
This is because my microsd is failing. Changed with a new one, and now it is failing again. I suppose my phone has become a 'micro sd destroyer'. Cannot do anything about it, so better to use the internal memory instead of the card for main use..... So how do I switch back to normal mounting (micro sd as micro sd and internal memory as internal memory and not switched up) ?
