Error While installing Ruby -

-

i have used this procedure.i m using linux mint.

i getting following error while installing.

e: unable locate package libreadline6-dev e: unable locate package libyaml-dev e: unable locate package libgdbm-dev e: package 'ncurses-dev' has no installation candidate e: package 'bison' has no installation candidate e: package 'subversion' has no installation candidate e: package 'libffi-dev' has no installation candidate

i think didn't installed rvm requirements .
install requirements libreadline6-dev , libyaml-dev , libgdbm-dev ,etc..
think solve problem.

install these command

sudo apt-get install build-essential openssl libreadline6 libreadline6-dev \ curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 \ libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison  \ subversion pkg-config

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
