you have problem loop logic:

if (result < 0)     continue;

if result < 0 don't increment i, , loop doesn't progress.

also, comparison wrong way around. result < 0 mean currently-tested date later current maximum. reason you're getting 01/01/0001 output because you're current code finds earliest date, , of array unintialised (and therefore lot earlier test values!).

switch if instead (and remove else entirely):

if (result < 0)     latestdate = dtlist[i];

android - getbluetoothservice() called with no bluetoothmanagercallback -

-
i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
