Android :: Not Able To Write To SDcard In Live Wallpaper?
Jan 16, 2010
I currently have a live wallpaper that is animated and works. However, I am trying to update the code and add in some lines which will save a file from a webpage and then read it. After reading it, the wallpaper would change its behavior. Anyways, I am having problems just saving the actual file, I know the code works because I have used the same code in previous applications. Are you just not able to write to the SDcard in a live wallpaper?

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 have my incredible set to use the live wallpaper "water". When I turn the phone off to charge at the end of the day, upon restart it defaults to the htc colors wallpaper.Is there something I'm doing wrong, is there a setting I'missed to retain the "water" live wallpaper after restart, or is this just normal behavior?

Does using "Live Wallpaper" use battery life more than fixed wallpaper. If so is the drain anything significant?

I need to write a fairly simple .csv file to the device's sdcard (so it can then be emailed via Intent). The below code does not write the file.
CODE:...........
More code here:
I flush and close out_stream. I can even seem to be able to read from the file on the device (printing above output, using fileinputstream, to an edittext.
How can I get to this file on the sdcard?

I am using a mt6582m device with kitkat 4.4.2 with supersu. I can use root to write to system, data and cache using es file explorer, can also read and write to any sd card, but apps like titanium backup, online android backup, ram expander can't read/write to sd card.
Eg.1: ti backup read backups, can do all operation except backup and restore.
I had read a lot, changing backup path didn't worked nor any odex file is there. Using v6.1.5.6.
Eg. 2: ram expander can create swap file on sd but can read it saying 'not found'. Swap can be used with cache partition.
Eg. 3: online nandroid backup says pat not vaild.
I had tried, sd fix app, manually editing platform.xml, xposed module to 'handel external storage', change permissions using es file explorer, editing ramdisk.
There is storage/sdcard0 and 1
Also mnt/sdcard and mnt/sdcard2 (symlinked)
Also mnt/media_rw/sdcard0 and 1 (not readable even in es file explorer)

Android 2.1 has API support for creating live wallpapers. This means that we can implemente our own live wallpapers w00t!
However what i like to see is a Tutorial on creating such a live wallpaper. Is there going to be added one? What about battery live?
Or maybe a link to the sourcecode to one of the live wallpapers in Nexus One?
When i run a 2.1 emulator and choose a live wallpaper it says: "No live wallpapers"

I am wondering how to set a background in Live Wallpaper for Android. It seems the only options I have are to create it using a canvas which I don't want. I want to be able to set up a time lapse of a tree that goes through the seasons. I'm assuming I'll be able to set the coordinates for the leaves and then just have different times to fall, but is it possible to have them expand or even change colors?

Anyone know of a wallpaper changer for only Live Wallpapers? I know there are a bunch for "still wallpapers", but I plan on using only live ones. Is there a changer that can handle that? I don't seem to be able to find one in the normal places I seek out apps.

When this is installed on a 2.1 phone, that has live wallpaper, the live wallpaper is not returned by getWallpaper() , because it just returns a Drawable, and live wallpaper probably is another thing. So the question is, is it possible to show a live wallpaper on the background of a 1.6 application? How?

I have created a small sample Live Wallpaper, and I want to use it with a small test Activity I have also created. However, I cannot seem to find an example of how to do this. The examples I have seen on the Web and in the Android sources all seem to focus on creating the live wallpaper itself, not how to link it to an Activity and display it behind the activity with transparency, etc. So far, all I have is a Live Wallpaper service, with no idea how to go about using it! Does anyone know where I could find _all_ the steps to do this?
