Hey folks,
I plan on using the following code to write to the SD card:
try {
File root = Environment.getExternalStorageDirectory();
File outFile = new File(root, "filename.ext");
FileWriter gpxwriter = new FileWriter(gpxfile);
BufferedWriter out = new BufferedWriter(gpxwriter);
out.write("Hello world");
out.close();
} catch (IOException e) {
Log.e(TAG, "Could not write file " + e.getMessage());
}
With the plan that if an exception is triggered I will then assume
that the SD card is not available (it's missing or maybe physically
set to read only) and revert to writing to built-in memory.
Is that jumping the gun? Do I need to do anything to the SD card
before I use it in my app? Do I need to mount it or check whether
it's mounted or writable? I've been having trouble finding an answer
to this in the reference docs.
Thanks!
Rob
