The predicament : all CSV examples are in reference to contacts, and the file read/write posts (the ones that I need) make the assumption that I am not a beginner and most don't even post any code leaving me nothing to learn on.
The hopeful solution : a link to a solid example of simply how to write to a CSV with my own custom fields and values, and how to read a CSV and load said values.

View 4 Replies View RelatedI cannot read and write extended characters (French accented characters, for example) to a text file using the standard InputStreamReader methods shown in the Android API examples. When I read back the file using: the string read is truncated at the extended characters instead of at the end-of-line. The second half of the string then comes on the next line. I'm assuming that I need to persist my data as UTF-8 but I cannot find any examples of that, and I'm new to Java. Can anyone provide me with an example or a link to relevant documentation? Code...
View 3 Replies View RelatedI 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);

do { st = in.readLine();
mVector.add(st);

} catch (FileNotFoundException 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 want to know how to get SMS Delivery Report setting which is stored in the /data/data/com.android.mms com.android.mms_preferences.xml. I wrote a application to read it with the following code:
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); boolean requestDeliveryReport = prefs.getBoolean( "pref_key_sms_delivery_reports", true);
Seems it does not work, it always returns the default value which is "true". Does anybody know how to read/write the SMS Delivery Report setting.
I m using Android 1.5 my data directory does'nt have the read/write permissions
System.out.println("DAta can write??--->"+Environment.getDataDirectory().canWrite());
System.out.println("DAta can read??--->"+Environment.getDataDirectory().canRead());
So please suggest me how to provide permission for the data directory.
What m trying to do is to create a file and add some content to it iin the Data storage of the emulator like as below
private void writeToSDCard() {
try {
File lroot = Environment.getDataDirectory();
if (lroot.canWrite()){
File lfile = new File(lroot, "samplefile.txt");
FileWriter lfilewriter = new FileWriter(lfile);
BufferedWriter lout = new BufferedWriter(lfilewriter);
lout.write("XXXXXXXXXXXXXXXXXX");
lout.close();
}
} catch (IOException e) {
Log.e(m_cTAG, "Could not write file " + e.getMessage());
}
}
There are a lot of different classes that can be used in various ways to read/write to files in Android. For example, you can make use of java.nio.ByteBuffer, FileOutputStream and BufferedOutputStream. Are there any general guidelines for what to use to read/write quickly to the SD card? For example, BufferedOutputStream seems as if it should make things faster but I'm unsure the buffer size should be set for. Specifically, I want to read/write byte arrays that are ~1Mb in size as quickly as I can.

View 4 Replies View RelatedIs there a right associated with write/read access to the sd card that needs to be set in the manifest.xml file? I'm currently trying to write to the sd card using a standard FileOutputStream here:
FileOutputStream out = new FileOutputStream("/ sdcard/images/"+imageName);
bmp.compress(Bitmap.CompressFormat.JPEG, 90, out);
But it doesn't seem to be working. It just says the location isn't found, which can happen if there are no permissions to read/write to the location.

I did a backup using Titanium Backup and Go Backup and after wiping my Motorola Defy, tried to restore apps, contacts etc. The problems I encountered were:
1) Go Backup can't recognize backup directory on SD card for some reason.
2) Can't move apps to SD. An error occurs: "Move Application: Failed to move application. There is not enough storage left." Needless to say, I have more than enough storage.
This is was I encountered by far, although I believe these are just a small part of the symptoms for a single problem.
Maybe its because there are no permissions, or moving apps is impossible because of an existing app files on the SD card.
What is the actual cause for this? Or is there a tool to fix the permissions on the Defy?
My new HTC desire is unable to read or write to my 8GB SD card which was previously inside my HTC HD touch.
Why is this? I've swapped the SD cards around - i.e. the 4 GB SD card which it came shipped with is now inside my HTC HD touch It doesnt have a problem reading or writingto the 4 GB SD card that it came shipped with. I would prefer not to have to format the card

I have two published apps that are pretty targeted to the user collecting their personal medical data (like Blood Pressure, etc.) and then, eventually sending it somewhere, if they choose.
I decided to put Read/Write permission on my ContentProvider, so if another app comes along that wants to the access that content, the user will be warned. The permission that is required is declared in my apps.
When the user installs my apps, they are also given a warning that the app requires that permission (even though it's the one that declares it), and it shows up in the Marketplace also.
The question is: Is it possible that the permission acceptance part of installing my app could be putting customers off? I don't know what other's acceptance rate is, but mine is around 50% of customers who download it have active installs.

I have a M919V Galaxy S4 which is compatible with both the i9505 roms and M919 (TMO) roms. I was on a i9505 TW rom and I decided to download a rom from the TMO section. When moving from a i9505 rom to a M919 rom, I had to flash the recovery corresponding to the model. So I downloaded the T-Mobile version of Philz Recovery, but I got a status 7 error. Then I downloaded the md5 version and flashed it via odin 3.07. It was successful. After flashing the recovery, I flashed Beanstalk rom for the t-mobile variant. Everything went fine until I tried to make a android of my current setup for Beanstalk. I kept getting errors. When I plug my phone in (with my sd card), and try to add or delete something, it say "remove write protection and try again". So I tried connecting my sd card to my sd card adapter. When I delete files from my adapter, the error message doesn't show up. BUT... after disconnecting and reconnecting it again, the files are back where they were. I tried reformatting it but nothing happens. It seems like my sd card is only read as write protected when connected to my phone but it has no idea which state it's in when connected to the sd card adapter.
