Android :: How's Android Directory Structure?

Jul 21, 2010

How the directories are disposed? Where do I copy my musics and pictures in my virtual device to test my apps? update: I entered the internet on the Android's virtual device, tried to save an image, and it says that "An SD card is required". I thought I've read in the android.developers.com that the device has a SD card by default. Anyway, I'll look for how to create it.

Android :: Mkdirs Returns False For Directory On Sd Card While The Parent Directory Is Writable

Oct 31, 2010

At some points while running my android application, I need to create a directory on the sd card, for a small number of users this fails and I can't figure out the reason for it... (I've found similar problems caused by the WRITE_EXTERNAL_STORAGE permission missing, it's there and it works for almost all users so I don't think this is reason) When mkdirs returns false I crash the program and log the following java.io.File properties, starting at the directory I want to create, then recursive printing properties of the parent directory and so on...

/sdcard/MyDirectory/Dir1/Dir2 (exists: false, canWrite: false, isDirectory: false, isFile: false);
/sdcard/MyDirectory/Dir1 (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard/MyDirectory (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard (exists: true, canWrite: true, isDirectory: true, isFile: false);
/ (exists: true, canWrite: false, isDirectory: true, isFile: false);

The strange thing is that the parent directory is writable (canWrite=true), I can't print the execute file permission but from what I've read, write is what you need when creating directories... What I've looked at so far is the WRITE_EXTERNAL_STORAGE permission, if the sd card is full and if the sdcard is mounted read only:...........................

Android :: Why Doesn't Droid Directory Match To Computer Directory

Dec 23, 2009

I have an app that instructed me to copy some data from my computer to the SDCard. So I plugged the Droid into the computer, mounted my Droid SDCard, looked at the directory, and copied the file. There are a bunch of files and folders listed (e.g. backups for apps, album artwork, etc.) as being on the SDCard. But when I go into Astro on the Droid and select "SDCARD" it shows "directory is empty." I don't get it. Why can't I see the folders and files on the SDCard that I can see on the computer screen?

How To Structure Android Timer App With Thread

Feb 5, 2012

I'm trying to create a simple Workout Timer for Android. The user creates a WorkoutPlan containing info such as total duration, total rest time, etc, the app will display a timer that updates every second.

Pretty simple to begin with, but I'm trying to build the app as properly as possible, i.e. separation of concern, correct techniques, responsive UI, ensure the timer will be accurate, etc.

Here's a simplification of what I have so far:

WorkoutPlan, the user can load/save different workout plans to the timer

Code:
public class WorkoutPlan {
public long duration;
}
TimerThread, this class implements `Runnable`, it takes in a `WorkoutPlan` in the constructor, start/stop, shows elapsed time.

Code:
public class TimerThread implements Runnable {
public boolean running = false;

[Code]....

TimerView, the custom view that displays the elapsed time

Code:
public class TimerView extends View {
private final Paint mBg;
private final Paint mText;
private WorkoutPlan plan;
private TimerThread timer;
private Thread thread;
private Handler handler = new TimerHandler();

[Code]...

Finally, WorkoutTimer, the activity that starts it off

Code:
public class WorkoutTimer extends Activity {
private TimerView mTimer;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {

[Code]....

A couple of questions:

Where's the best place to create the `WorkoutPlan` object? Currently it's done in `TimerView`. Should it be done in the `WorkoutTimer` activity instead? If yes, how do I pass the `WorkoutPlan` object to `TimerView`?

The app works fine the first time, but crashes when I go to the home screen then back to the app the second time. What's causing it to crash? Is it the theading?

Currently I'm using a `Handler` in a new `Thread`. Is this ok or would a `TimerTask` be better? Where's the best place to start the thread? Am I correct to put all the threading code in `TimerView`?

Am I correct to add synchronized to all the methods in `TimerThread`?

Android :: LogCat - Any Way To Change Structure Of Log Messages?

May 6, 2010

I fear the answer is no, but before I change the structure of all of my log messages: Is there any way to do this: $ adb logcat *:S com.myappname.*:V
Or in words: I want to silence every tag that goes to logcat except the ones that begin with com.myappname. Currently my classes print into the log with this.getClass().getName() as the tag - typing each tag out individually in the filter isn't an option, so is there anyway to use the wildcard? The above command doesn't work, because it just silences every class, including the ones I've explicitly told to be verbal. I've also tried:
$ adb logcat -s com.myappname.*:V $ adb logcat com.myappname.*:V *:S
to no avail. I have a feeling I might have to log in a more constant fashion. Or I might just use log4J.

Android :: Application With Multiple Views - Best Practice For Structure?

Jun 20, 2010

I am new to developing for android. I have a question regarding some best practices. My app is like a dashboard from which multiple different "sub-activities" can be started and done. I am wondering what is the best way to structure the app. One way is to have different layouts and load and unload them appropriately. The other is to start new activities using intents. At least this is what I have gathered from what I have read.

Android :: Creating Static Data Structure On Application Startup For Android

Oct 27, 2010

In my application, I am going to create a few listviews that are dependent on the listview before it. For example,Then, depending on user choice, will go next screen, let's say, it contains a submenu of each type of school,that may be different or may be the same to other states.What I want to know, is how to populate these different lists dynamically as the user goes on? I don't know what the best of doing this is, and I seem to be looking in the all the wrong places because I keep getting stuck. Once all the data is added into whatever structure is used, it will be static. I basically just need help as to how to code information into some sort of hashtable or anything of the sort that can be easily referenced, and later when the Application is updated, be able to add more schools/states/submenus etc.

Android :: How To Achieve Modularity Structure Of App Subcomponents On Android?

Feb 9, 2010

My Android main application will consist in a main program, with a few pre-installed modules.Then I want to offer different modules later, best would be as separate files. Modules like: location, weather, agenda.How would you accomplish this?I want to keep in the database the modules that are installed/present. So I must put sometimes the modules into database, maybe by detecting if there are present at launch time. The main app will work based on these modules.How can I build these modules as separate files? They won't be an entry point in my application. So they must not be an application in the navigation menu.

Android :: Data Structure Used For SMS Messages In Android

Does anybody know what data structures are used to the store messages in an SMS client app, and whether there is an existing API for this.I was perhaps looking at implementing a link list for the purpose but if the work has already been done in an API then perhaps it would be unnecessary to commit time to the task that could be spent programming other parts.

Android :: How To Structure Simple Android Apps?

Aug 31, 2010

I've run into an organizational problem with an application I am working on, on the Android platform. The application uses sensors as input and OpenGL as output.Assume very simple drawing code and somewhat complex control system code that will attempt to refresh at 60ish Hz. I am looking for performance, maintainability and easy of development implications, so any and all input is valuable. Also I am a complete novice when it comes to Android or mobile development so if you can show me the light with a third alternative that'd be great too.

Stuck In Global Structure Of Quiz App

Sep 20, 2012

I recently started programming in Android, and as a beginning project I am trying to build a logo quiz app. The idea: You see a splash screen after opening the app (play game - about). Play game takes you to a new activity called LevelSelector.java where you can choose the level you want to play. Clicking on a level takes you to another new Activity Level.java.I created a SQLite db with 20 questions in it which I install with a DBHelper.java class, every question also has a level column.

However, I get lost in my global structure. Since I work with different levels I don't want to make a new class for every level. I guess I lost the overview due to my lack of programming in android, but I figured the best way to learn it is (after I watched tutorials) to build an app myself..

Android :: Loading Google Maps Data Into Searchable Data Structure

Mar 2, 2010

For my CS bachelors I am doing a Senior project using android and google maps.My vision was to do a (relatively) simple Dijkstra shortest path using google maps road data. I was going to add elevation change along with 2D distance. I am doing well playing with maps in android but I am completely stumped trying to access google maps data in any sort of searchable form.How would I go about accessing the data for say intersections of roads (lat/long) in a particular area?There has to be a way to pull that data in some sort of tree form. It seems like it may be possible with kml?Any pointers would be awesome.I want my paths to follow roads but If i cant this is going to turn into an orienteering application fairly fast.

I have been looking at Android's javax.net.ssl package, but am still confused as to how it works with the underlying JNI glue in place.Would anyone be able to tell me how the provider is linked to the abstract classes, given that the user calls the abstract classes directly from their code. I thought that usually the user would call the subclass, but in this case it seems to be the opposite.
