我现在真的很沮丧..我想从DropBox下载文件并将该文件保存到SDCARD ..我得到的代码为：
private boolean downloadDropBoxFile(String dbPath,File localFile) throws IOException{ BufferedInputStream br = null; BufferedOutputStream bw = null; try { if (!localFile.exists()) { localFile.createNewFile(); //otherwise dropBox client will fail silently } FileDownload fd = api.getFileStream("dropBox",dbPath,null); **br = new BufferedInputStream(fd.is);** bw = new BufferedOutputStream(new FileOutputStream(localFile)); byte[] buffer = new byte[4096]; int read; while (true) { read = br.read(buffer); if (read <= 0) { break; } bw.write(buffer,read); } } finally { //in finally block: if (bw != null) { bw.close(); } if (br != null) { br.close(); } } return true;
}
这里我在br = new BufferedInputStream line..Pls帮助中收到错误
解决方法
我找到了方法：
File file= new File("/sdcard/New_csv_file.csv");
OutputStream out= null;
boolean result=false;
try {
out = new BufferedOutputStream(new FileOutputStream(file));
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
DropBoxFileInfo info = mApi.getFile("/photos/New_csv_file.csv",null,out,null);
Log.i("DbExampleLog","The file's rev is: " + info.getMetadata().rev);
Intent JumpToParseCSV=new Intent(context,ParseCSV.class);
JumpToParseCSV.putExtra("FileName",file.getAbsolutePath());
Log.i("path","FileName"+ file.getAbsolutePath());
((Activity) context).finish();
context.startActivity(JumpToParseCSV);
result=true;
} catch (DropBoxException e) {
Log.e("DbExampleLog","Something went wrong while downloading.");
file.delete();
result=false;
}
return result;
谢谢大家….
