Hi JBQ,
Thanks for you reply, and I appologize for the delay in getting back
to you.
The detailed log of the issue is list as following:
01-01 07:06:27.936: ERROR/AndroidRuntime(479): Uncaught handler:
thread Thread-11 exiting due to uncaught exception
01-01 07:06:27.936: ERROR/AndroidRuntime(479):
java.lang.SecurityException: Cannot write secure settings table

01-01 07:06:27.936: ERROR/AndroidRuntime(479): at
android.bluetooth.IBluetoothDevice$Stub$Proxy.disable
(IBluetoothDevice.java:577)
01-01 07:06:27.936: ERROR/AndroidRuntime(479): at
android.bluetooth.BluetoothDevice.disable(BluetoothDevice.java:134)
And I searched the built environment, and found out the following code
snippet from the auto-generated file IBluetoothDevice.java:
public boolean enable(android.bluetooth.IBluetoothDeviceCallback
callback) throws android.os.RemoteException
{
android.os.Parcel _data = android.os.Parcel.obtain();
android.os.Parcel _reply = android.os.Parcel.obtain();
boolean _result;
try {
_data.writeInterfaceToken(DESCRIPTOR);
_data.writeStrongBinder((((callback!=null))?(callback.asBinder
()):(null)));
mRemote.transact(Stub.TRANSACTION_enable, _data, _reply, 0);
_reply.readException();
_result = (0!=_reply.readInt());
}
finally {
_reply.recycle();
_data.recycle();
}
return _result;
}
// async
public boolean disable() throws android.os.RemoteException
{
android.os.Parcel _data = android.os.Parcel.obtain();
android.os.Parcel _reply = android.os.Parcel.obtain();
boolean _result;
try {
_data.writeInterfaceToken(DESCRIPTOR);
mRemote.transact(Stub.TRANSACTION_disable, _data, _reply, 0);
_reply.readException();
_result = (0!=_reply.readInt());
}
finally {
_reply.recycle();
_data.recycle();
}
return _result;
}
>From the source code, in fact, I could not find the difference between
the two functions disable and enable in their implementation. I also
compared the file IBluetoothDeivceService.java, and still not find
where the permission is needed. The only permission is
BLUETOOTH_ADMIN. Maybe other permission rather than the permission
WRITE_SECURE_SETTING is needed?
