python - I want collect all characters and events that end with a certain text? -

-

i want collect data before specified text or ends it, have tried following: 

   .{30}value_*|.{55}value2_*

but have specify how many characters want collect before specified ending text, want collect of them (note im dealing python/perl regexes here)

try like:

"(.+?)value_*|(.+?)value2_*"

without knowing data looks can't more specific. break down: .+ matches 1 or more characters, while ? makes non-greedy, doesn't consume entire line @ once, , parentheses capture match (in python @ least).

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
