Android :: Accessing Java SIM Card Information
May 26, 2009
My query is regarding access to USIM card information from an android application. My requirement is to read certain pre populated parameters on the sim card at application startup. Is this use case possible? I found an api in the developer reference that interacts with the sim card, but it is limited to only sms and geolocation information.. http://developer.android.com/reference/android/telephony/gsm/package-. i wish to read the MSISDN, and a shared secret key stored on the sim.

I have a separate class that includes the database, a cursor, and all the accessor methods for database information. I import the cursor into all the classes that update or use the database. However, I get a runtime error whenever I try to start an intent that uses the database.

I want to send some information from PHP to Java. Why? Because I have a database on my server, and I get information from my database using PHP scripts.
Now I want to send that information to my client in Java. How can I do that?
I send information from Java to PHP by POST, and it works well, but I don't know how can I do the reverse.code...

I wrote an app that saves a camera picture to the SD card, then accesses the file later to display it into an ImageView. This works fine for all devices except the HTC Droid Eris (maybe the version Eris is running?):
ImageView img = (ImageView) findViewById(R.id.ImgProfile1);
BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 4; Bitmap bm = BitmapFactory.decodeFile("sdcard/" + filename, options); img.setImageBitmap(bm); Is there a different method of referring to the sdcard location on 1.5, 1.6, or the Eris itself?

I'm using Android 4.2.1 on Galaxy note 10.1. I am travelling and photographing and have 64 folders and 6gbs of pics on a 64*gb*sd card. The last two attempts to transfer images from my camera via USB have all failed with various weirdness, like seeing the pics in folder with Gallery app once, only to have the folder completely disappear on next viewing. I have lost over 800 photos like this and I can' t find anything about a folder limit in android but see lots of similar posts with sd card problems. All fine up until I hit that limit, now my whole image recording process while traveling appears to be unreliable. Is it possible the pics are there but not viewable somehow?

Now I need some information about SD card storage. I know that the API Environment.get External Storage Directory() can return SD card path. But if an Android phone have some no-removal SD card, how do I get this storage information. I think the removal able SD and no-removable should be at different path.

I'm bought my Eris a week ago and am not familiar with all of its functions. I'm trying to place my music files on the SD card. Whenever I plug it into my computer and mount it shows a USB drive under "Computer", but whenever I click it I get a popup saying that the drive can't be found. I've downloaded HTC Sync and that let me create a music file, but then I couldn't do anything with it.

Can you randomly look at your SD card from the phone? Can you put regular files(like excel files) on the SD and access them with the phone? I've tried with no success. I was able to put the file on the card but had no way to get to ou it..

I need some way to access the SD card on my SGS2 GT-9100 from certain applications in windows. E.g., when I try browsing for a destination folder in the phone through these programs, my phone is not recognized at all.
The long story:The problem I am trying to overcome is copying of images from my computer to my phone without changing the creation date (for sorting purposes). When copying from my computer to my device this attribute changes an thus all images have the same date and there is no way of making any sense of which picture was taken when.
So my plan is to get access to the images on my device, after altering there dates, and use a program which will change the creation date from the modification date (which holds the original date taken of the pictures).

Basically, I'm unable to make a briefcase folder on my phone's SD card. I can make new folders, but I don't get the range of options that you would normally get when hovering your cursor over the "New" option (when opening the "New" context menu) when accessing my SD card via a usb cable plugged into the phone; I'm actually able to get the context menu when accessing the SD card by sticking it straight into the computer, but when it remains in my phone (and the phone's hooked up to the computer), I don't get the context menu.
Here's what I want:
Obviously, I can just use the SD card by plugging it directly into the computer, but it's inconvenient to take off the case, remove the back, etc. I'd rather just plug a USB cable directly into the phone. Why is my phone preventing me from getting that context menu when doing so though?

I'm using a Gemini Devices Gem1031BK 16GB tablet running Android 4.1.1 and Nova Launcher. I have 2 main problems.
Problem 1, if I move my photos to the SD card I can no longer view them on the tablet. It is as though they no longer exist, but the tablet will run Apps stored on card.
Problem 2. I keep getting "App Not Installed" messages although the icon is still present on the desktop. This happens with various apps, Candy Crush Saga, BBC iPlayer, BBC Media Player etc. The only thing I can do then is reload the app from the Play Store.

Does anyone know if there is a app, or phone mod that allows you to access the SD Card on the phone, at the same time as it's being used as a drive.I'm getting tired of transferring things like icons, and wallpaper to my phone, then having to unmount the drive before I can use them. Especially if I'm just trying out new icons.Is it possible to have my desire set to disk drive, and access it at the same time?

I am a Mac user (photographer/ videographer). I also rely heavily on my iPod Touch when mobile (i can often find a wifi signal when i am out and about). I use iCal on the Touch and iCal on my Mac as well as the address book on both everyday and as a Mobile Me user, my two devices sync so everything is mirrored and up to date. I also HATE AT&T for their terrible signal strength and coverage and have been a loyal Verizon customer for many years and this is why I don't have an iPhone. Okay, all that being said, is there an easy way to still use everything I love and rely on with my Mac (the calender and address book, mainly) and easily sync all of my existing information and future info to an Android based device? How easy is it to use an Android device with a Mac? I don't want to have to manually re-enter my entire address book into a new device.

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!
