android-file

I tried many ways but i can't do this . I have a *.txt file . i want share it via Bluetooth , wifi , email and ... . When i used this code i cant share the file: File file = new File(Environment.getExternalStorageDirectory(), "Email-Ghap/Emails.txt"); Intent sharingIntent = new Intent(Intent.ACTION_SEND); sharingIntent.setType("*/txt"); sharingIntent.putExtra(Intent.EXTRA_STREAM, file); startActivity(Intent.createChooser(sharingIntent, "share file with")); Totally i want this : when user clicked on share button and choose one email sender like Gmail for sharing . the file must be attached file

The question here talks about file name length limit , I'm interested in the overall permitted path length (if it matters). There's this filesystems limits table here , though I'm not sure which applies to Android of which version. I tested with 1024 characters long path and it works in every device I tested on. I didn't go further up, maybe it mess up the sd card. I think, max file name length should be less than 128 and max file path length should be less than 1024 for Android. Again these are just my assumptions, they could be wrong. So be careful. Its not defined for Android as a whole-

is there any solution how to choose the saving files location? maybe with the original file browser, to choose the destination? thank you! All you need is Android Directory Picker Maxim Better to save files with your app namespace: String extStorage = Environment.getExternalStorageState(); path = extStorage+"/Android/data/com.mydomain.myapp/"; It will be deleted when app gets uninstalled. Here is actually everything about data storing. http://developer.android.com/guide/topics/data/data-storage.html From the above link: If you're using API Level 7 or lower, use getExternalStorageDirectory() ,

I am trying to convert a file from the sdcard to Base64 but it seems the file is too big and i get an OutOfMemoryError. Here is my code : InputStream inputStream = null;//You can get an inputStream using any IO API inputStream = new FileInputStream(file.getAbsolutePath()); byte[] bytes; byte[] buffer = new byte[8192]; int bytesRead; ByteArrayOutputStream output = new ByteArrayOutputStream(); try { while ((bytesRead = inputStream.read(buffer)) != -1) { output.write(buffer, 0, bytesRead); } } catch (IOException e) { e.printStackTrace(); } bytes = output.toByteArray(); attachedFile = Base64

In my app I added the possibility to add and save pictures for everyday day, represented by a Fragment . In order to save the picture on the SD card, I currently use the function File.createTempFile : File imageFile = File.createTempFile(imageFileName, MyApplication.JPEG_FILE_SUFFIX, MyApplication.getAlbumDir()); I actually also tried with the standard way: File imageFile = new File(MyApplication.getAlbumDir(), imageFileName + MyApplication.JPEG_FILE_SUFFIX); Both are working, but in my case the first one is better than the second one because the function createTempFile adds a long random
