Java Examples for android.net.SntpClient
The following java examples will help you to understand the usage of android.net.SntpClient. These source code samples are taken from different open source projects.
Example 1
| Project: cnAndroidDocs-master File: NtpTrustedTime.java View source code |
@Override
public boolean forceRefresh() {
if (mServer == null) {
// missing server, so no trusted time available
return false;
}

final SntpClient client = new SntpClient();
if (client.requestTime(mServer, (int) mTimeout)) {
mHasCache = true;
mCachedNtpTime = client.getNtpTime();
mCachedNtpElapsedRealtime = client.getNtpTimeReference();
mCachedNtpCertainty = client.getRoundTripTime() / 2;
return true;
} else {
return false;
}
}Example 2
| Project: MobileSensing-master File: TimeProvider.java View source code |
/**

//
// for ( String provider : getProviders() )

// // is connected
// // thus we do force a route to host request here
// if ( !ConnectivityWrapperImpl.getInstance().testHostReachability(
