Android :: Save Variable And ArrayList Of Object

Dec 1, 2009

I created an application with loging and an arraylist to fill a ListView.

If i am calling or i need to check my mail, sometimes i lost the context of my application (variables and the listview !)

It is a little complex to save arraylist in SharedPreferences and i am not an expert in SQLite.

Do you know a solution to keep persistent my data (variables and the arraylist) during the use of my application?

Android : Takes Drawable Object - Scale Image - Save Memory?

Aug 23, 2010

I need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...

I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?

Android :: How To Convert A URI To File Object?

Feb 28, 2010

I want to convert this into a File object, and only a File object - I need to pass it to another constructor that requires a File. How can I convert a URI like this to a File object? If I try File newFile = new File(myURI);I get an error in Eclipse suggesting that I should convert the URI to a String. Supplying URI.getPath() in the constructor doesn't help either.

This relates to the 'How can I convert android.net.uri object to java.net.uri object?' question, which unfortunately seems to have no good answer, but I want a File object out, not a java uri. I don't mind if I have to write it to a bytestream and back again - whatever is the best way.Apologies if I'm cross-posting my own question, but I thought I might need to make things a bit clearer.

Android :: Save File To Sd Card?

Apr 22, 2010

I am trying to find the best way to save files to the phone. Basically I have an XML file on a web server that I would like to be able to save on the phone. Should I create a specific folder in my project to save to and if so how do I save the file. Or should I make it to where when you click the Save button it checks for an SD card and if there is and SD card create a folder (if one isn't already there) and save the file in the new folder or save it to the phone? If someone could explain the most efficient way of saving files for my app and how to save the file from the web server I would greatly appreciate the insight. Any tutorial links would be awesome.

Android :: Cannot Save Picture / File Not Get Written

Apr 23, 2010

I am still not able to save a picture when I send an intent asking for a photo to be taken. Here's what I am doing:
Make a URI representing the pathname
android.content.Context c = getApplicationContext();
String fname = c.getFilesDir().getAbsolutePath()+"/parked.jpg";
java.io.File file = new java.io.File( fname );
Uri fileUri = Uri.fromFile(file);
Create the Intent (don't forget the pkg name!) and start the activity

private static int TAKE_PICTURE = 22;
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
intent.putExtra("com.droidstogo.boom1." + MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult( intent, TAKE_PICTURE );
The camera activity starts, and I can take a picture, and approve it.
My onActivityResult() then gets called. But my file doesn't get written.
The URI is: file:///data/data/com.droidstogo.boom1/files/parked.jpg
I can create thumbnail OK (by not putting the extra into the Intent), and can write that file OK, and later read it back).
