Đã được hỏi nhưng tôi không tìm thấy giải pháp nào. Đối với ứng dụng bluetooth, tôi đang sử dụng bluetoothShare.class
.Bluetooth không gửi tập tin đến thiết bị khác
mã nguồn của tôi để gửi các tập tin vào thiết bị mục tiêu
MainActvity.class:
Set<BluetoothDevice> devices = btAdapter
.getBondedDevices();
final String btDeviceName = selected_deviceName;
BluetoothDevice device = null;
for (BluetoothDevice itDevice : devices) {
if (btDeviceName.equals(itDevice.getName())) {
device = itDevice;
}
}
if (device != null) {
ContentValues values = new ContentValues();
values.put(BluetoothShare.URI, uri.toString());
values.put(BluetoothShare.MIMETYPE, "image/jpeg");
values.put(BluetoothShare.DESTINATION,
device.getAddress());
values.put(BluetoothShare.DIRECTION,
BluetoothShare.DIRECTION_OUTBOUND);
Long ts = System.currentTimeMillis();
values.put(BluetoothShare.TIMESTAMP, ts);
final Uri contentUri = getApplicationContext()
.getContentResolver().insert(
BluetoothShare.CONTENT_URI, values);
Log.v(TAG, "Insert contentUri: " + contentUri
+ " to device: " + device.getName());
Toast.makeText(getApplicationContext(), "Success",
Toast.LENGTH_LONG).show();
} else {
textStatus
.setText("Bluetooth remote device not found");
}
} else {
textStatus.setText("Bluetooth not activated");
}
}
else {
Toast.makeText(getApplicationContext(), "No devices found",
Toast.LENGTH_LONG).show();
}
và blueToothShare.class:

Cảm ơn bạn đã trả lời .. app.setmSocket (mmSocket); ứng dụng là gì .. – Arut
Tôi nghĩ rằng mã của bạn là để kết nối các thiết bị ngay. – Arut
quên app.setmSocket (mmSocket); .. điều này chỉ dành cho tôi. –
