File transfer doesn't work!?

[Erik-Lehnsherr]

Dear Sir,

Thanks for the sharing! I have tried your code on my 2 Android 9 devices. Although the two devices can connect each other, the file transferring is unsuccessful?

I have also tried this code on Android 10 device. However, when I clicked "Choose Document" icon on the top right corner, the app quitted unexpectedly?

May I know if any tips for fixing this issue? Any suggestions will be highly appreciated!

Thanks!

Yes, I am also facing this same issue. The error occurs in doInBackground method in while loop. byte[] buf = new byte[512]; int len; while ((len = inputStream.read(buf)) != -1) { outputStream.write(buf, 0, len); total += len; int progress = (int) ((total * 100) / fileSize); publishProgress(progress); Log.e(TAG, "File sending progress：" + progress); }

遇到相同的问题，选择文件的时候应用崩溃。
