Android :: Where Are Application Files Located?
Oct 30, 2010
I have a new Galaxy S. If I go to Market and install an application, everything is done automatically without giving me options.
So, my questions:
a. What is/are the files that are downloaded?
b. Where are files saved to?
c. What happens during installation? Is there just one binary? Or a binary with lots of other files? How can I find out the files that belong to a particular application.
If it is a paid application, how can I save it so that I can reinstall again. I am having so much trouble learning this new phone that I have to restore it to factory state already twice on the first day.

/sdcard/TWRP/ is empty except for a single .twrps file
/storage/emulated/0/ is same as /sdcard/
/storage/emulated/legacy/ is same as /sdcard/
/storage/sdcard0/ is same as /sdcard/
I know the backups exist, as when I'm in TWRP, I can hit RESTORE, and see my backups listed there, but if I goto ES File Explorer, and try to do a search for that same filename, I get no results.

I would like to use Android for Model-Driven-Software-Development.
For this, I need to locate the Android Model in the SDK. I already searched a while for it, but were not able to find it. Has anyone an idea where it could be?
Is it possible, that it is the AndroidManifest.xml-File in the folder android-sdk-platformsandroid-xandroid.jar? After unpacking this file, I am not able to open that file correctly on Windows XP, because a lot of characters have the wrong character set.
Or is it also possible, that it is only located in the source code?

What will be the best storage choice for an application with huge amount of mb in media? The application will not be in android market.
First choice was to use assets/ folder. At least, 160MB of audio is shipped with the application. When I moved all the media to the assets/ folder, I end up with:
"Conversion to Dalvik format failed: Unable to execute dex: null"
And reading: http://code.google.com/p/android/issues/detail?id=2328 suggest me that maybe it's not such a good idea to ship all the media in an .apk file. I think that the problem has nothing to do with large .java files, as it arises when I copy the bunch of audio to assets/.
I was thinking in using the sd card storage. But, I don't want the user to accidentally remove the media files. I want it to be private, not accesible to possible deletions. So, another approach is to use the private storage and download the media in the application first run, or something like that.

I've created an application which uses around 15 small audio files. Right now I'm using mp3 files and each is around 200KB. These files are stored in my res/raw directory. I'm using SoundPool class to play the files in my application. I'm hoping to put this application on the android market place. Can one of you suggest what is the best way to store so many audio files? Will my application be scalable? Is wav or ogg format better approach instead of mp3? Please let me know.

I am looking for an application that can handle large PDF files smoothly. I have tried adobe reader, pdf viewer and RepliGo. They were not very impressive, therefore I have come here for suggestions. Repligo reader I think was better out of the three but I couldn't view a PDF file that had scanned images on it. Was hoping someone could recommend an app that could handle large PDFs and PDFs that contained scanned images.

I m designing a big android application, where there are XMLs to store temporary data, images captured by camera and other details. Which is the best way to protect them from outer access from phone or from PC. XMLs can be encrypted. And images too, however there are times when they need to be accessed very often and encrypting-decrypting is very heavy operation. XML encryption is manageable but images cause memory problems. Is there any alternative way, something at folder level ?

I am trying to port a VoIP application based on SIP protocol to android.
I want to test this application first on two emulators running on two different PCs connected via LAN.
The problem is that, the communication is not happening when I run the application on two PCs. The same application works when I run it's non-android version on the same PC's.
I have identified the following problem. Let's say there are two computers C1(192.168.1.101), C2(192.168.1.102) connected in a LAN.
Emulator E1 is running on C1 Emulator E2 is running on C2
The application uses UDP protocol and the port being used is 5060 on both computers.
I have setup port forwarding on both the emulators. This is the command used for that in Android console. redir add udp:5060:5060
When we make a voip call from E1 with the URL 192.168.1.102:5060, then E2 responds to the call, but what ever E2 sends in response is not coming back to E1, and hence E1 is timing out.
When I observed the log files, actually E2 is sending the response to 10.0.2.2:5060, which is the C2's loop back address(127.0.0.1). How do we resolve this issue?
I have gone through the developer guide where they have mentioned about two emulators communicating on single PC. But looks like this concept doesn't work when we run emulators on two different computers.
I tried 'redir' command for port forwarding and added INTERNET permission, still it doesn't work.
My question is, Is it possible to implement this communication on two emulators? and if yes, How to do this?

I have an application that can read and write txt files to the phones sdcard. By using this code for reading files:
@Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); mFileNameOpen = files.get(position);
String st = null; mVector.clear();
notepad.mNewEmpty = false; try { File f = new File(Environment.getExternalStorageDirectory()+"/ notepad/"+mFileNameOpen); FileInputStream fileIS = new FileInputStream(f);
BufferedReader in = new BufferedReader(new InputStreamReader(fileIS));
do { st = in.readLine();
mVector.add(st);
}while(st!=null); in.close(); ...
} catch (FileNotFoundException e) { e.printStackTrace();
} catch (IOException e) e.printStackTrace();
and this to write them:
try { File root = Environment.getExternalStorageDirectory();
File fileCheck = new File(root, "/notepad/" + fileNameSave + saveExtension);
boolean exists = fileCheck.exists();
if (!exists) { if (root.canWrite()) { File textFile = new File(root, "/notepad/" + fileNameSave + saveExtension);
FileWriter textWriter = new FileWriter(textFile);
BufferedWriter out = new BufferedWriter(textWriter);
out.write(SAVEAS); out.close(); written = true;
} else { written = false; else { written = true; showMaybe = 1; showDialog(DIALOG_SAVE_EXISTS);
catch (IOException e) {Log.v(getString(R.string.app_name), e.getMessage());
This has been working fine on my Tattoo and all the emulators I've tried this on. But it does not seem to be working on moto droid. Is there something different to consider with moto droid? Or have I missed something in the manifest maybe?

I am building an app on android and running into an error and while searching on net, came across your posting on this and changed the eclipse.ini to increase Xms and Xmx params but still this error does not go away. I am using Eclipse IDE for Java with Andrioid SDK 2.1 on Mac OS. Please help or please point me to someone who might know. Btw, this error only happens when i add external jar files (which i need for my project). here are the list of external jar files that i have in my classpath.)
// httpclient-4.0.1.jar from apache
// httpcore -4.0.1.jarfrom apache
// commons-codec-1.3.jar from apache
//commons-logging-1.1.1.jar from apache
// json_simple-1.1.jar from google ........

I am working on an android app that needs to act on a few data files totaling around 30MB. I put together a test and the emulator failed with OutOfDiskSpace. Debugging on a device failed with even a smaller data size. After reading through the google groups, it appears that the application size limit isn't stated anywhere and nobody from google has been forthcoming with specifics about this. Given that there are iPhone apps that are over 100MB in size, putting such a small limit on Android apps seems weird, except just for the fact that you have a relatively small amount of total available app storage space (< 100MB).What techniques do you use to deal with this limit? If you have an app that needs more than 10MB, do you put it on a web server and deal with downloading it the first time? If so, how do you handle access control so that only your app can get the data?

It would be useful for me to have an application to exchange files between my Tattoo and a PC through WiFi.
I was thinking about something standard, like FTP or Windows file sharing.
Do you know if an app like this is existing ?

I know it is possible to use TelephonyManager to get information like: service state, device ID, Sim Operator, etc...
Is it possible to edit some of this information?
Couldn't find .set() functions on Android.com documentation but I've found the GSMPhone.java source code which includes functions like .setNumber1Number() (used to set/edit the number?).
I basically want to know if it's possible to edit the phone number located on Sim card (Settings->About->Status->My Phone Number).
Appreciate any answer, even a simple "NO", if it's indeed impossible.
