对不起,
我没有使用 Android 文件系统的经验,我很难通过文档和教程来理解它。
我正在尝试将文件从某个位置复制到我的应用程序的外部存储。
final File filetobecopied =item.getFile();
File path=getPrivateExternalStorageDir(mContext);
final File destination = new File(path,item.getName());
try
{copy(filetobecopied,destination);
}
catch (IOException e) {Log.e("",e.toString());}
public void copy(File src, File dst) throws IOException {
InputStream in = new FileInputStream(src);
OutputStream out = new FileOutputStream(dst);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
Toast.makeText(mContext,"COPIED",Toast.LENGTH_SHORT).show();
}
public File getPrivateExternalStorageDir(Context context) {
File file = context.getExternalFilesDir(null);
if (!file.mkdirs()) {
Log.e("", "Directory not created");
}
return file;
}
我收到以下错误:
