View 2 Replies View RelatedI 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.
I am trying to create a file ,if it doesnot exist and tried to write some data to it. The same program I did in java, it was running fine.But when I try to do the same thing in Android I am getting NullPointerException at the place where I am trying to write data to file. And also, I did not find any new file in the current directory .
View 2 Replies View RelatedLets say you have a normal textview, with "Stackoverflow" written in it, I would like to know if it it possible to rotate the textview about -90°, to have the S at the bottom and the W at the top of the screen?
of course, i could write my text in an image, rotate it and use it that way, but im interested in text right now.
I'm trying to create a textView in the parent activity onActivityResult but the textView does not appear. There is an ImageView that takes up the whole parent activity. I can create a textView and place it, and it should go on top of the imageView?
In the parent class:

Intent chooseClothesIntent = new Intent(this, ChooseClothesActivity.class);
chooseClothesIntent.putExtra("menuId", menuId);
startActivityForResult(chooseClothesIntent, 1);
}[/HIGH]

then in my new activity:
[HIGH]@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
try {
ClothingItem ci = mListContents.get(position);
String imagePath = ci.getImagePath();

eg. "Mountain View, CA"
What I want to achieve is to create this text to act like a Link - color,underline, focusability etc.
This link doesn't need to direct anywhere - surrounding view has attached onClick listener that fires google maps intent.

View 8 Replies View RelatedI would like to know how to write to file. I have tried using OutPutStream out = new FileOutPutStream(fileName); out.write(byte [], 0, length);This way always returns Parent directory or File is not writable.I have also used openFileOutPut(fileName, MODE_PRIVATE) method but this method works properly if it is called from the same class which has extended Activity and I am writing to the file in different class and that too in different thread.I have tried to get the Application Context through getApplciationContext and call openFileOutPut method but still theres something wrong that I am doing.So please can someone suggest me a proper way to write to a file.

How do I create a shared directory with read/write permissions to all applications installed on my phone and that is not on the sdcard?
I tried that :
File f = new File("/tmp");
f.mkdir();
but it is not working.
My app creates a lot of TextView objects and this turns out to be really slow. A look at the traceview output reveals that the bulk of the time is spent in the TextView methods that grab all the default parameters from /res and /util. The thing is, all my TextViews share 99% of these parameters. Is it possible to clone a TextView rather than create one from scratch? If not, what about if I created a pool of TextView objects and reused them?
Just to give some context, I'm generating a spreadsheet to show some data provided from an online source and the spreadsheet can be as big as 20 columns by 50 rows = 1000 cells, each with a TextView. It takes about 25 seconds just to create 1000 TextViews on my Moto Droid.
I'm trying to write a file from an Http post reply to a file on the sdcard. Everything works fine until the byte array of data is retrieved. I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest and tried many different combinations of tutorials I found on the net. How my app writes file is by using a thread. Specifically, a thread is invoked from another thread when a file has to be written, so giving an activity object didn't work even though I tried it. The app has come a long way and I cannot change how the app is currently written. CODE:..................

View 8 Replies View RelatedThis should be trivial, but for whatever reason I can't find any easy way to do this. Coming from C# where this is a 1 line call, I don't understand why Java makes this so complicated, and on top of that android leaves even that out of its libraries. Anyway all I want to do is write an
org.w3c.dom.Document
that I have populated to a xml file. It should be as easy as opening a stream and writing document.toString(). But that doesn't work. My hope is I'm just missing something.
I wrote a file to the sdcard, but it failed as follow:String sdcardFIle = "/sdcard/xxx.txt" FileOutputStream fos = openFileOutput (sdcardFile, Context. MODE_ WORLD_ WRITABLE ) ; openFileOutput failed, because fIle "/sdcard/xxx.txt" contains a path seperator. It is so strange. Is there another way to handle the situation?

View 9 Replies View RelatedToday, i tried to read and write file on the android. but it seems that file write mode is only provided for SD card? most of article is asked about SD card written. Is there no way to save data internal side?So when i install the application to real device. then its application installed in SD card or internal space? because we have make it log file from our application for everytime while application run.So, how do we write the file to SD card and specified the absolute path where we saved? to load this file.
View 3 Replies View RelatedI'm trying to create a file on the sd card.but that throws a FileNotFoundException. Isn't OutputStream supposed to create the file, if not found on disk?

View 6 Replies View RelatedMight sound crazy, but it's what I need to do. I want to take a Bitmap object and use the XMLPullParser/XmlSerializer to write this to a flat file. Obviously I will need to read the XML tag back into a Bitmap object.So somehow I have to turn my Bitmap into a String and then turn that String back into a Bitmap. I will do some searches on Base64 to see if I get any good examples.
