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?

View 9 Replies View RelatedJust started developing apps and am having a small problem. I can test the apps on the emulator but I cannot test them on my physical android device. When I am asked to select a running device I get a device listed as: Serial Number/name:? AVD name: N/A Target: unknown etc,
It seems that my device is being picked up but not able to be used. When I try to run the app I get an "Must set android.target.avd" error.
Is there something I am missing?
I am using netbeans 6.7.1 on Ubuntu 9.10, everything up to date. I have a G2-Touch from T-mobile, if someone tells me where to find it, I will post any other needed information.
I found out that you can use something like this to create a file:
CODE:............
When running the above code I get an IllegalArgumentException stating:
CODE:......
And Im guessing the "/" is not appreciated. I wanted the "/" since I need to write the file to the root directory of the device, as stated in the API in trying to follow:
CODE:.........
Question is: how do I place a file in the root-directory? I have been looking around for an answer, but havent found one yet.
My program contains a file with the name "size.text", which contains just a word "15". If a user choose a value from a spinner,say 17, then the chosen value should be stored in the file and replace "15". I have added the permission to the program <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission> But somehow i can not make the chosen value be written to the file. Here is my code...

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);

I have a standalone GPS enabled data recorder in my car that can function as either a USB host or device. (Its a class 0x00h USB device). I currently connect to it via a WM 6.5 app running on my Palm Treo 750. I would like to port my WM 6.5 app to an Android phone. (I don't have a specific Android phone in mind, I would like it to be as generic as possible).Replicating the GUI is not that difficult, but I am having trouble getting started on the USB communication. I'd appreciate it if someone could point me towards an example, or the appropriate tutorial.
View 1 Replies View RelatedI 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)
Anyone know if it's possible to obtain the physical height or altitude of your device, using the sensors or by any other means?
View 4 Replies View RelatedI just got 'my first app' working on Eclipse, but I can't use my physical device as a target. I have Android 2.3 Gingerbread, Samsung Galaxy Ace(aka Cooper), Win 7. Latest versions of Eclipse and ADT. On adb devices, it doesn't show up, only the emulator if that's on.
USB Debugging is turned on and I downloaded three different drivers: the one Windows automatically downloads, one using USBDriverTool and the Universal ADB Driver.
If it's relevant, I also had trouble installing the ADT plugin with Eclipse, I posted about it here in a separate thread.

View 1 Replies View RelatedI'm working on a project that includes a test system for OEM devices. The supporting infrastructure is complete, however I'm having difficulties getting ROMs to run on the emulator. Of course the AVDs generated by the SDK work fine, but my next step is to run a binary intended for an OEM device. I understand that the emulator would require different drivers than a physical device, so I can't simply drop the same binary onto it and expect it to run.
Tweaking the AVDs generated by the SDK is about the limit of my knowledge. I've looked into pulling the system.img and other partitions from the ROM with ones from the emulator, but that doesn't work since the emulated hardware doesn't match what the drivers expect. I assume some modifications to qemu and some reverse engineering of the OEM ROM might be required to obtain my goal.
Assuming I have access to the binaries (but not the source) used by an OEM to construct their ROMs, what would be involved to obtain an emulator that matches the physical device, so I can run the compiled ROM on the emulator?
I cant get this to work anymore
Here is my code...
On both the emulator and my actual phone (tattoo) I seem unable to browse the SD card - when I run ddms and use the File Explorer, I can browse /data or /system fine, but /sdcard refuses to open, and its permissions appear to be "d---------" (which of course might be the problem).
Similarly when I use ddms's "Put file on device" it fails:
29:43 E/ddms: transfer error: Permission denied Failed to push about.html on SH9CELG00306: Permission denied
The above is for my actual phone but I get a similar error on the emulator (which does have an /sdcard).
I am new to android. I need to list available files in device or SDCard in the android emulator 1.5.
View 3 Replies View RelatedIs there a way to find out what the physical file name is of an application? I would (desperately) like to delete the Amazon MP3 application from my Droid. I have an app called "Ghost Commander" and I can navigate to the directory (/system/app) on my phone that contains all the applications. And I can delete any of the files there. However, what I can't seem to do is determine which of the .apk files is the one for Amazon MP3.
Is there a way to get that information? Or does anyone know which .apk file is "Amazon MP3"?
I have a cell phone which name is Huawei Ascend P1. Now I have a problem, that is the devices can not bootup into Android's home and I can not write anything into flash, even using fastboot.
When booting, the screen stays on the welcome logo, and stay there forever, and adb could connect to linux shell on the phone. I can see all file on the phone, and I can save files after "mount -o remount / /", but after reboot, the file is gone.
If I use fastboot to flash a recovery into my phone, by follow command:
fastboot flash recovery recovery.img
The command line prompt says OK, but when it reboots, it still reboot into the previous recovery.
