If I am going to be reading files from the SD Card, where do I put them during development? Also, when I install the app, will it include these files and put them to the SD Card?
View 1 Replies View RelatedI searched the Incredible forums and sub forums and could not find an answer to this question, though I am sure it has been asked: If I want to go from my stock 2 GB card to a new card, and I want to preserve data AND have all apps still be able to read whatever data they were reading off the card, do I just transfer the files from one card to the other? I bet the only thing I need to make sure of is that new card is formatted with the same file system as the original card, right? I know copying data from one card to the other will preserve data, but I want to make sure I have no problems with apps, either, after inserting the newer card.

Suppose I have some sample APK file named "SampApp.apk" which contains classes inside "com.android.sampApp".
Is there any tool in Android SDK which shows the package name when APK file is passed as a parameter.
As the Class files are compressed to dex file I am not able to check the actual package name.

I'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.
float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();
That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):
balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?

View 1 Replies View RelatedI want to access camera pictures and camera pictures only. I could not find a specification of how the default camera application stores pictures...
1) Is /sdcard/DCIM a standard of any kind? On the Android devices I've used, it looks like the default camera app always writes to this location. Are there devices where pictures are written to a different location? 2) Is it specified that camera JPEGs will always be accessible on the file system? (And not in some private database for example?)
I'm hoping that if the above two are true, then I can simplify my code by simply reading the jpeg's in /sdcard/dcim. Or do I have to use MediaStore.Images.Media.query() for reliable access to camera images?

How to code for reading a pdf file in android? i want to build an app like RepliGo reader. So, Please enlighten me to read pdf by using android sdk or ndk.
View 1 Replies View RelatedI have an image on a private file.
I read the file, create the drawable, and assign it to an ImageView.
The ImageView has WRAP_CONTENT so the size is automatic.
On 320x480 screens, the image looks good
But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100.
Of course it has something to do with the density but not sure how should I resolve this.
This is my code...
if I then inspect the size of the icon, android thinks the size is 100x100, when really is 150x150.
Looks like its reducing the image by the density.
Can anybody explain this and how to avoid this.

View 1 Replies View RelatedI have to create an app that draws a map reading data from a text file : for example the text file can be like
. index x y orientation
vertex 1 0 0 0
vertex 2 5 0 0.5
vertex 3 10 2 0.3
so i need to do in java something like fscanf does in c (fscanf scans the text file for known formatted data... example, in the file i written i know each line has a string float float float and i need to put them into a specific data structure that can be a list of elements "vertex"
next, when i have all the data, draw a simple image rappresenting the data..
my questions are...
there is a function like fscanf?
and then.. what's better for drawing the 2d map? i have tu use Opengl? At the end i have to draw the image pixel by pixel.. i hope there is something easier then openGL
how to apply to lag fix by partitioning my sd card. I followed the guide to the t using Paragon Hard Disk Manager. When I deleted my external SD card partition, it wouldn't let me re-partition it. Now my computer won't even recognize my phone. When I go into settings->SD card and phone storage, both the internal and external SD card show "Unavailable" under the space heading. The unmount and format options are greyed out as well. What do I need to do to get my phone back the way it was? I would just like my phone back the way it was and would like to get this lag fix working. Here are the video tutorials I followed and the original site I found.
