Android :: App Static Storage ?
Sep 30, 2010
I am creating an Android application which will have some embedded music inside of it ( ~ 80 MB ). I was planning on putting it in the res/raw folder.
Since android stores that all in it's internal memory, is this way too large? What are my options? I have come up with the following:
Copy resources out of internal storage and onto the SD card when application first starts. Afterwards remove from internal storage (is this possible?)
Download music from the web when the application first starts.
I would really prefer not to have to go with option 2 since I want the app to be entirely offline and the static music is not going to change (except between releases).

I am currently developing a simple info app on various uni campuses. I want the app to operate predominantly in an offline state thus I want to store all my information locally. The data within the app will not be subject to any change thus I was wondering what the best (practice) method was to store such data? Basically should I be storing the info in a SQLite db, java file or xml?

i want to display a msg to the user (msg box or Toast) when exception happend in a static SQLite Database class that i use. the problem is that i cant call a non static method in a static class , how can i handle this. this is the class
private static SQLiteDatabase getDatabase(Context aContext) {
and i want to add something like this in the class when exception happen but context generates the problem of reference to non static in static class.
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();

I'm having some issues with the old "Cannot make a static reference to a non-static method" error in my Android program. I am creating a sand falling game (similar to the Powder Game) and I created a class called Control to create a Control Bar at the bottom of the screen with a slider for brush size (that works fine) and a button to pop up a Dialog to allow users to pick the selected element. However, when I call DemoActivity.showDialog(2) from my code, it gives the static reference to non-static error (DemoActivity is the main activity of my application). I also tried changing it to just Activity.showDialog(2), but I got exactly the same error!
Here's my code:
CODE:................
I fixed it by adding the following to my Control.java code:
CODE:..........
And then calling control.setActivity(this); from my onResume section of DemoActivity.java!

I have Eclipse Juno and I'm working on an app with that.
The main activity will have a scrollable menu that takes you to all the other activities.
So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.
Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)
- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
- Item ??: Centred, bold, non selectable title (Tools)
- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.
I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.
I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.
I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C

I have been finding it convenient to extend Handler in many of my activities to handle messages specific to the activity. The handler sublass is an inner class of the activity and needs to access its state. I am wondering if there is any performance difference between making the handler subclass static and passing in the activity explicitly in its constructor or making the subclass an "instance class" and letting the vm worry about my accessing members of the containing activity.
The static approach:

I've bought this chinese clone of the SIII, it's a MT6575. It's great except for the internal storage, which supposedly is 500MB but there seems to be an invisible SD storage which is 2GB. It's really confusing... When I go to Settings -> Storage there are 3 memories: "Internal Storage" (claims to be 4GB but it's fake, it's actually 500MB), "Phone Storage" (claims to be 16.5GB but it's probably 2GB), and finally my SD, "SD Card" (32GB).
The thing is, I'm having problems downloading big apps because apps go to "Internal Storage" which is 500MB only, and which files are stored in the "Phone Storage" (maybe internal & phone are actually the same?). However when I go to Settings -> Apps, on the "Downloaded" tab, the apps are in "Internal Storage" (500MB), and on the "On SD Card" tab, it shows that apps are in "Phone Storage" (the ones I moved to SD). This means my 32GB SD isn't being used by the system when I send apps to SD probably.
Also, my 32GB SD card is found in /mnt/sdcard2, and the /mnt/sdcard... I don't know which storage is that.
So basically all this is happening because I tried to Link2SD with my 32GB SD doing all the 2 partitions stuff and so, but Link2SD never detects the "secondary SD" which is the 32GB SD, as this fake SD card, "Phone Storage", is probably what the programs thinks to be the SD card.

For some reason my Incredible won't mount both the internal phone storage and the SD card storage at the same time. What I mean is...when I plug my phone into my PC I only get a single popup asking to mount the phone's SD card storage, but not the internal phone storage.If I remove the SD card (or unmount the SD card using menus on the phone) and then toggle the connection type from Disk Drive, to Charge only, and then back to Disk Drive (to burp the connection), the internal phone storage will mount, but the SD card won't mount because it has been removed.When I connect my wife's incredible, my computer sees both the SD card storage and the internal storage (as expected) and gives me prompts for both. I took the SD card from the problematic phone and put it in the "good" phone and there are no issues at all (IE.. both the internal storage and SD storage mount). This of course means there is no issue with the SD card.

My phone keeps telling me I'm low on space, but I cleaned out my sd card and I know I haven room. Just today my phone at the top scroll bar said I was running low on space, and that my text memory was full even though I only had very few.

On my galaxy tab 2 7, with Android 4.3, I have two choices of memory storage, emulated and extSdard. Im wondering if the emulated is actually on a like Cloud system or are the files still on my tablet? Also, if emulated storage is for multiple users, does this mean another device is connected besides my tablet?

I bought my new phablet that was powered by 4.1
im shocked with how the manufacturer of my device(cherry mobile) designated their storage. the phone storage is 2gb and internal is 500 mb.
it is not a problem if i could write apps on phone storage by default but even though the 'write to phone storage' is checked, when i downloaded an app, the internal storage still losses free space.
so is it possible to extend internal storage?

I used this to check the amount of space on my A2SD partition of my SD Card. However I've noticed that as well as INTERNAL storage, there's something called SYSTEM storage. Which is considerably bigger than whats left of my internal space.Is the INTERNAL used for Multimedia files as this thread suggests?Internal Storage vs Phone Storage.If so. How come my multimedia files have ended up there, when they've always been saved to my SD card.

So if I do a Factory Reset on the phone it still has some of the old photos/videos I took, which leads me to believe it doesn't fully clear the device of everything, just the settings that I changed are returned to their factory defaults (duh!).I was curious if I do the Clear Storage option, which means turning off the device and holding one of the volume toggles while holding the power button - would that mean that the entire Android OS would be removed, or does it mean it does a format of the phones entire partition and re-installs Android (similar to a reformat/recovery partition on a computer)? In which case I would need to reactivate the phone doing the simple *228.

Sorry if this is a complete NOOB question, but what is the difference between the internal storage which is 6.6GB and the phone storage, which is about 750MB? How do I access the 6.6GM of storage? What am I missing here?

I was working on Freescale iMX31 board, I ported android and it was working fine , but when it came to integration of WiFi & Bluetooth, android forum recommended me to do static compilation for porting over android !
Can I know why some drivers have to be statically compiled before it is ported over android? It was not the case with other drivers which when integrated with android, they worked perfectly well like serial port, usb etc..

I use a single static class in my code that defines a static field which I'm reusing between Activity onStop/onStart invocations. Here's a scenario:
User clicks on "Authorize" button (static data is initialized) Activity is stopped and web browser is called
Browser executes callback and Activity is restored (static data is reused)
At least one of my users reports the failure at step 3 which I cannot reproduce but which looks like reset of static data.

As a first step toward a speech recognition project, we wrote a simple voice recording application based on the information in this thread:
http://groups.google.com/group/android-developers/browse_thread/threa...
It is working; however, the audio is extremely poor too static for our needs. As a comparison, we did a similar audio file captured with audacity on a PC and it was much better. Has anyone been able to record high quality audio with the android dev phone? According to the documentation of MediaRecorder, there is only one audio encoder "AMR (Narrowband) audio codec" and three output formats--3gpp, mpeg, and raw AMR:
http://developer.android.com/reference/android/media/MediaRecorder.html
According to wikipedia, AMR encoding is only 8hz. Is there a better option available perhaps a lower-level API compared to MediaRecorder? We are testing on Windows XP, with a Logitec USB microphone, eclipse ganymede, and we are using all the defaults for an android 1.5 app (no emulator command-line options. We defined the SD card in AVD manager).

When starting a new Activity, I want to pass a complex object and do so by using this approach:
MyActivity.COMPLEX_OBJ = myComplexObj; // which is definitely NOT NULL! Intent intent = new Intent(); intent.setClass(this, MyActivity.class); startActivity(intent);
and then in MyActivity:
@Override public void onCreate(Bundle bundle) { if (COMPLEX_OBJ == null) { // report to Flurry ... } ...
}

I have noticed in my application(s) that after a call to Activity.finish() that the static variables that I declared in my classes still hold the values that they were changed to during the activity's life cycle. Upon the re-launch of the activity, the program does not re-instantiate the variables as declared or set them to the default java behavior. Is there something that I can do to cause this to happen, other than re-setting every static variable in my application?

Why is the use of static final variables encouraged to declare constants over just final variables? The use of static sounds logical when there will be many instances of a class but is this argument correct when used for a Android activity. In fact, since the Class instance will be around even after the activity finishes and is eventually garbage collected, it seems like all these constants will still be in memory until the class loader is around. Also, does the compiler inline non-static final variables(ints and String) just like it does for static final variables?

I'm trying to handle exceptions at a global level. My understanding is that the only way to do this is with an UncaughtExceptionHandler. However, this reduces one to the primitive java file and network i/o packages. I'd like to be able to broadcast an intent or bind to a service. Is there some way to interact with the android packages to retrieve a context in a static manner? I could probably do some hack workaround with a thread local, weak-referenced context set at the time of the exception handler, but I'd rather avoid that nastiness.

I have a ListView with several columns and I need a header row at the very top that labels each of these columns that *does not* scroll with the rest of the ListView. I am using addHeaderView right now, but I've ran into 2 problems:
1) The header scrolls. I need it outside of scrolling so that it's always "floating" on top.
2) Each column in the header isn't lining up with the columns in the listview. I can make the header columns and data columns all line up perfectly if they're all in one big TableLayout, but how would I get the header to be outside of the scrollview yet also stay uniform and inline with the data columns?
