cordova - checking of internet connection of device using phonegap -

-

trying use cordova 2.0.0 , using code checking of internet connection 

document.addeventlistener("deviceready", ondeviceready(), false);  function ondeviceready() {     alert("ready");     db = window.opendatabase("loginintro", "1.0", "loginintro", 1000000);     db.transaction(populatedb, errorcb, successcb);     checkconnection(); } function checkconnection() {   alert("connection");     network = navigator.network.connection.type;     alert("fdfd");     var states = {};     states[connection.unknown]  = 'unknown connection';     states[connection.ethernet] = 'ethernet connection';     states[connection.wifi]     = 'wifi connection';     states[connection.cell_2g]  = 'cell 2g connection';     states[connection.cell_3g]  = 'cell 3g connection';     states[connection.cell_4g]  = 'cell 4g connection';     states[connection.none]     = 'no network connection';     alert('connection type: ' + states[networkstate]); }

but getting error on line 

network = navigator.network.connection.type;

and error is:

04-09 15:20:23.989: e/web console(13329): uncaught typeerror: cannot read property 'connection' of undefined @ file:///android_asset/www/js/lib/helloworldjs/alldatabse.js:14 04-09 15:20:39.419: e/cordovawebview(13329): cordovawebview: timeout error! 04-09 15:20:39.419: d/cordova(13329): cordovawebviewclient.onreceivederror: error code=-6 description=the connection server unsuccessful. url=file:///android_asset/www/index.html

you have small mistake in code. should alert('connection type: ' + states[network]);

in addition, make sure have these permissions:

android

app/res/xml/plugins.xml

<plugin name="networkstatus" value="org.apache.cordova.networkmanager" />

app/androidmanifest.xml

<uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.access_network_state" /> <uses-permission android:name="android.permission.read_phone_state" />

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
