When I run the code bellow in the virtual android (1.5) it works well, TextSwitcher shows first 80 chars from each txt file from /sdcard/documents/ , but when I run it on my Samsung Galaxy i7500 (1.6) there are no contents in TextSwitcher, however in LogCat there are FileNames of txt files.
My Code:...................
And I am able to write contents of those files though LogCat!

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 replaced my original sdcard with a sandisk 16gb card. Everything went well until I started getting these blasted read on errors. Earlymon suggested a fix from another board but I don't have a stand alone card reader so I couldn't do it that way.
I was wondering if I just backed up all my stuff from my sdcard to my iMac and then just reformatted my sdcard via the phone, would that solve my problems?

How to remount /sdcard directory to read/write on emulator?
I read this:

But i don't know how to apply that to remount /sdcard directory in read-write mode?
"Every Android-compatible device supports a shared "external storage" that you can use to save files. This can be a removable storage media (such as an SD card) or an internal (non-removable) storage. Files saved to the external storage are world-readable and can be modified by the user when they enable USB mass storage to transfer files on a computer." PROBLEM: I cannot write to a file on the sdcard. QUESTION: Is it possible to write to a file on the sdcard?
If YES, what do I need to do to make File.canWrite = true? I am using Android 2.1 update 1, API level 7, Eclipse, and HVGA skin. I am running my app / troubleshooting on the Android SDK ADV. When the AVD is running, I check settings > sdcard total 49.21MB, available 49.07MB................

View 1 Replies View RelatedI have images uploaded on the simulated sdcard on my emulator. I downloaded them from the browser, using the long-click on each image.
When I look at the file explorer in the DDMS perspective, I see that they are in the directory sdcard/download.
Now if I want to download some audio files and use them in an app to, say list the title of all audio files, will they go in the same directory? (I am trying to push the audio files manually from my computer to the emulator).
This doesn't seem right. Shouldn't the media files of different types (pictures, audio, video) go into different directories?
Also, thinking this through a little, how is something like this related to the physical directory on the sdcard?
Uri mMedia = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
I want to show the list of media files (.mp3, .mp4...etc) available in sdcard. How can I do this?

View 4 Replies View RelatedI cannot play my mp3s without one or two songs repeating over and over, before going to a new song, then the player goes back to the same repeated ones. I noticed that extra files are being created continuously in the mp3 folder. Even if I make a play list the player still manages to go back to these invader files. Is that a micro sd card or android issue. I first notice it after I install ics on my SGS I9000. Now I am JB (I9300OXADLI8).

View 1 Replies View RelatedToday android phones are coming with an internal storage which is called the internal sdcard. Because of this the need for external sdcards is vanishing day by day. But when your phone is factory reset you lost all the data stored in it while in case of external sdcard you have an option to save your data. If you accidently lost all the data stored in your phone then don't worry I have a solution to get it back. This trick will work on phones having mass storage mode support, if you are running android 4.1 jellybean and above then root your phone to get mass storage( the tutorial is different for different phones),
If you have accidently lost all your files, photos and videos from your phone then after this do not copy new files to the phone. This also include clicking photos and capturing videos. If you copy new files to the phone then you are actually reducing your chances to get back your deleted photos and videos and other files. In short just don't download anything to your phone, do not use the internet on your phone till the time when you get back your lost files back.
This trick will only work on android phones having mass storage mode and MTP (Media Transfer Protocol) options. If your device is rooted then you can enable mass storage mode on your android phone. After enabling mass storage mode you can get back deleted photos, videos and all files from the internal storage of any android phone.
Requirements
1. Recuva for Windows 7, Windows 8
2. A USB data cable.
Now Follow The Steps Below
-Download and install recuva. While installation do not uncheck any option.
-Now connect your android phone in mass storage mode. Connect it to pc a notification will appear in the phone, tap it to enable mass storage.
-Now open My computer and you will see Removable disk.
-Open recuva and click Next, on the next step All Files will auto selected. Again click Next. Then choose In a specified location and click Browse.Choose the removable disk or MTP disk here and click Next.
-In next step put a check mark in Enable Deep Scan and click Start.
-After scan is finished you will see the list of all deleted files. Green circles is means that file can be recovered while red circle means unrecoverable file.
-Now check the box next to Filename to select all files. Click Recover on the bottom right and choose Desktop .Your deleted files will be recovered.
Currently I am having an issue with my SD card storage.
It started when iMusic told me i was out of space, on a 4gig SD card when i had mayb 5 songs on the phone!
So i went to my astro manager file manager to delete some files just to see. i keep getting "error deleting files" on anything i try to delte, ive taken the card out rebooted etc etc.
It makes me think the card may be locked? as its not even letting me save anything to it now.
Should i just root the dang thing to avoid problems like this?
I can delete files by going into the generic "music" app and long touching the song and selecting delete.
My phone is stuck in a bootloop, I tried flashing new roms, wiping everything, even doing a nand restore, still stuck. I want to wipe my sdcard too but I don't want to lose anything, is there any commands that allow me to push everything from my sdcard to my computer?

I can't seem to copy files to the sdcard inserted into the phone. When I try to do this with Windows Explorer, it just hangs there, and the sdcard area of the phone gets really hot. Once I unplug the USB cable Windows Explorer resumes, but the phone is still stuck there and unresponsive to any button/touch screen presses, and the phone remains hot. Copying from the sdcard works.
View 3 Replies View RelatedI'm on a S4 (I9505) phone and a lot of media files and also nandroid files are disappering from the sdcard (SDXC 64Gb). Yes, deleted. Most probably mounting and unmounting the sdcard, or rebooting, are removing the nandroid and media files.
I've used both TWRP and Phip recoveries. They work only if I unmount the storage card and reboot. Otherwise, in the first reboot, file are gone. Some users here in xda say we need to use short backup names. But it did not work for me.
Maybe it should be solved by the ROM side. But I'm not lucky and not finding a way to get a solution, not even using different kernel versions. Changing the WRITE_EXTERNAL_STORAGE permission suggested in many sites does not solve the issue [URL] ..... New ROMs seems to have incorporated this solution, but the problem is still there.
I also not being able to change the permissions for the mnt folder as suggested elsewhere here in xda. The operation (even my phone rooted with SuperSu) is not successful.
External SDcard is useless if we cannot trust on it.
I have an A4 document only with text. Is it possible to reduce the size of the pages e.g. with reducing the amount of words per line?
View 2 Replies View RelatedI could not read wave files emailed to me from my answering service and their technician said:
<beginning of technicain comments> Regarding the Verizon Droid user playing "wav" files. I did a little research and found this to be a problem for many, many, Droid owners. Our wav files are GSM 6.10 audio format, 13kbps bit rate, mono, 8kHz sample rate. Droid does not support the GSM 6.10 wav encoding format. Many voice mail systems, answering services, and MagicJack use this format. Neither the Droid manufacturer (Motorola) nor Google has a fix this problem yet.
I did find reference to a $3 program available for the Droid that may help our customer out though. Since we don't have a Droid to play with, I can't tell you if it will work or not. The program is called "Remote Wave". <end of technicain comments>
SO, I purchased this program at the Android market. Remote Wave from Walter Yongtao Wang and I have 24 hours to get a refund. It did not work nor could I get my money back. At this point I am hoping that remote wave will get updated and work.
