storage

Can someone explain in detail about the various storage locations in Android, /sdcard/ (along with /root/ directory and other system-level directory) /storage/emulated/0/ /storage/emulated/legacy/ /storage/sdcard0/ Really confused with these? And are there any methods to access them programatically whenever needed? AnV I can't speak for storage paths on all phones. But I can explain you clearly with respect to my phone; Coolpad Note 3 - running on Android 5.1. Because, the storage locations or paths may vary on other mobile phones depending on your vendor/manufacturer and different versions of

I want to save locally an object which has circular references. What are my options? My first thought was using HTML5 local storage but I can't stringify this object due to the circular references. Specifically I'm trying to save the DOMSelection object of the current selection. Example: var sel = window.getSelection(); var selstring = JSON.stringify(sel); // Breaks here ... localStorage.setItem("selection",selstring); The only way I could get the stringify to work now is by ignoring certain objects like so: var selstring = JSON.stringify(sel,function(k,v){ if( k=="anchorNode" || k=="baseNode"

In my app I am using osmdroid for working with map. Map tiles are downloaded and kept in /storage/osmdroid . The application requires permissions WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE . If I deny access to storage, map is not shown. Is any way to show map without access to phone memory? https://github.com/osmdroid/osmdroid/wiki/FAQ Fresh off the wiki press. Yes you can change the location to application private storage, in which case it should work just fine. Pro tip: set these before loading any map views. OpenStreetMapTileProviderConstants.setCachePath(...)

I have been stuck on this for a while now and have looked at various tutorials for help but have not yet succeeded. I have essentially utilised the camera function in my app to take pictures and display a preview of it BUT it can't save taken picture. Here is the java code containing my attempt to get it functioning according to tutorials: public class Activity_Camera extends Activity implements View.OnClickListener { ImageButton ib; ImageView iv; Intent i; public static final int cameraData = 0; Bitmap bmp; @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R

I am trying to write a native library for my application so that i can do all file operation in the native code. I read that getExternalStorageDirectory() give the path of the external storage of directory. My question is how can i access the same without hard-coding the location to some string? Is there any function in android ndk that can give the same function as getExternalStorageDirectory() of java in C++ code? JNI is your friend, and this isn't too complicated, as getExternalStorageDirectory is a static method. This function gets the value, and changes the working directory to it, for

I am trying to create a folder in external storage and I followed a couple of other threads here. However, even though I seem to be doing what they indicate, creation fails. Here's a piece of code boolean mExternalStorageAvailable = false; boolean mExternalStorageWriteable = false; String state = Environment.getExternalStorageState(); if (Environment.MEDIA_MOUNTED.equals(state)) { mExternalStorageAvailable = true; mExternalStorageWriteable = true; } else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) { mExternalStorageAvailable = true; mExternalStorageWriteable = false; } else {

I have an Android application and I would like to read and write an ArrayList<MyClass> to the Internal Storage. The writing part works (I believe, haven't tested it yet :-) ) : ArrayList<MyClass> aList; public void saveToInternalStorage() { try { FileOutputStream fos = ctx.openFileOutput(STORAGE_FILENAME, Context.MODE_PRIVATE); fos.write(aList.toString().getBytes()); fos.close(); } catch (Exception e) { Log.e("InternalStorage", e.getMessage()); } } But what I want to do now is read the whole ArrayList from the Storage and return it as an ArrayList like so: public ArrayList<MyClass>

I'm making a content script extension for Google Chrome, it adds functionality to a website's page. I want to add a couple of options, not big deal really, I'd just need two strings (none of which are sensitive user data). From this answer , I assume I need a background page, which I'd rather not add to my extension - I don't want it to gain unnecessary weight. Do I really need a background page, or I could have an options page without it (and which storage could I use)? UPDATE As of Chrome 20 you can now use the Storage api..... http://code.google.com/chrome/extensions/storage.html Old way

I'm creating a basic 2D game (well a game engine) and I've currently been developing the file formats for my data. Of course, for this game to run, I will need cache. I find it quite unprofessional to leave all the data for the game to not be in a single file (well not necessarily, as long as the files are in a cache format of some kind). So that's why I've came here to ask. I was thinking of doing a zip file but I feel like that isn't the best way at all. I was also thinking of doing another binary writer which will have headers (type of file, "location") and an enclosing tag for each of the
