Is it possible to copy a folder present in sdcard to another folder present the same sdcard programmatically ??
If so, how to do that?
An improved version of that example:
// If targetLocation does not exist, it will be created.
public void copyDirectory(File sourceLocation , File targetLocation)
throws IOException {
if (sourceLocation.isDirectory()) {
if (!targetLocation.exists() && !targetLocation.mkdirs()) {
throw new IOException("Cannot create dir " + targetLocation.getAbsolutePath());
}
String[] children = sourceLocation.list();
for (int i=0; i<children.length; i++) {
copyDirectory(new File(sourceLocation, children[i]),
new File(targetLocation, children[i]));
}
} else {
// make sure the directory we plan to store the recording in exists
File directory = targetLocation.getParentFile();
if (directory != null && !directory.exists() && !directory.mkdirs()) {
throw new IOException("Cannot create dir " + directory.getAbsolutePath());
}
InputStream in = new FileInputStream(sourceLocation);
OutputStream out = new FileOutputStream(targetLocation);
// Copy the bits from instream to outstream
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
}
}
Got some better error handling and better handles if the passed target file lies in a directory that does not exist.
