我在蓝牙文件或消息传输过程中遇到应用程序加载问题。
我的代码如下
final ArrayList<String> todoItems = new ArrayList<String>();
mArrayAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,todoItems);
Button btnClick;
BluetoothAdapter bluetooth = BluetoothAdapter.getDefaultAdapter();
if(bluetooth != null)
{
// Continue with bluetooth setup.
}
if (bluetooth.isEnabled()) {
// Enabled. Work with Bluetooth.
}
else
{
// Disabled. Do something else.
}
String mydeviceaddress = "";
String mydeviceaddress1 = "";
String mydevicename = "";
Set<BluetoothDevice> pairedDevices;
BluetoothDevice[] pairedDevicesArray;
String status = "";
String FnlDeviceAdd = "";
if (bluetooth.isEnabled())
{
try
{
pairedDevices = bluetooth.getBondedDevices();
if (pairedDevices.size() > 0) {
// Loop through paired devices
for (BluetoothDevice device : pairedDevices) {
// Add the name and address to an array adapter to show in a ListView
mArrayAdapter.add(device.getName() + "\n" + device.getAddress());
FnlDeviceAdd =device.getAddress();
status = mydevicename + " : " + mydeviceaddress + " : " + bluetooth.getState();
//String filePath = Environment.getExternalStorageDirectory().toString() + "/Munnar/1.jpg";
String filePath = Environment.getRootDirectory()+ "/devicefriendlyname.txt";
ContentValues values = new ContentValues();
values.put(BluetoothShare.URI, "hello");
//values.put(BluetoothShare.DESTINATION, FnlDeviceAdd);
values.put(BluetoothShare.URI,Uri.fromFile(new File(filePath)).toString());
Toast.makeText(this, "mydeviceaddress "+mydeviceaddress, Toast.LENGTH_LONG).show();
values.put(BluetoothShare.DIRECTION, BluetoothShare.DIRECTION_OUTBOUND);
Long ts = System.currentTimeMillis();
values.put(BluetoothShare.TIMESTAMP, ts);
Uri contentUri = getContentResolver().insert(BluetoothShare.CONTENT_URI, values);
}
}
}
catch(Exception ex)
{
}
}
else
{
status = "Bluetooth is not Enabled.";
}

另一个蓝牙设备无法接收文件
有人可以帮我解决这个问题吗？任何人都可以告诉我文件或消息传输哪里错了吗？
像这样更改我的代码以发送文件但无法成功
`ContentValues values = new ContentValues();
values.put(BluetoothShare.URI,Uri.fromFile(new File(filePath1)).toString());
values.put(BluetoothShare.DESTINATION, FnlDeviceAdd);
values.put(BluetoothShare.DIRECTION, BluetoothShare.DIRECTION_OUTBOUND);
Long ts = System.currentTimeMillis();
values.put(BluetoothShare.TIMESTAMP, ts);
Integer records = null;
if (Strput.length() != 0) {
records = Integer.parseInt(Strput.toString().trim();
}
if (records == null) {
records = 1;
}
for (int i = 0; i < records; i++) {
Uri contentUri = getContentResolver().insert(BluetoothShare.CONTENT_URI, values);
currentInsert = contentUri.getPathSegments().get(1);
`
