Android ACTION_GET_CONTENT from Dropbox sources

Thanks for that. I have not had any problems with reading the file. I am therefore unsure what the problem was that the other posters met.

I have read and write permissions set.

I initially used code like this (based on suggestions found online):

ParcelFileDescriptor mInputPFD = null ;
           try {
                mInputPFD = getContentResolver().openFileDescriptor(returnUri, "r");
           } catch (FileNotFoundException e) {
                e.printStackTrace();
                System.out.println("File not found...");
                return;
           }
if(mInputPFD!=null){
    fd = mInputPFD.getFileDescriptor();           
     FileInputStream fis = new FileInputStream(fd);
    //process the input stream
}

I tried the more direct method suggested above and it also worked:

FileInputStream fis = null ;
    try {
            fis = (FileInputStream) getContentResolver().openInputStream(returnUri);
    }
    catch (FileNotFoundException e1) {
             e1.printStackTrace();
             System.out.println("File not found...");            
             return ;
    }

 //process the input stream

I am using targeted Android API 19.

Can I assume that the ContentResolver#openInputStream(fileUri) method will also work on API 18 and lower?
