For support of the dark and light themes.
Also:
Redefine mFolded and call it mIsFolded. Previously,
the view started with mFolded = false (which implies to me
the initial state is unfolded) and yet the view
started in a folded state, which seemed contradictory.
Create updateFoldedState() with code from onClick() (In
preparation for subsequent commit.)
It only applied to pre-ICS devices.
ConnectivityManager.ACTION_BACKGROUND_DATA_SETTING_CHANGED is no longer
broadcast.
ConnectivityManager.getBackgroundDataSetting() always returns true.
This was dead code. The exception message will always start with either
"SMTP response is 0 length" from checkLine() or else "Negative SMTP reply"
from NegativeSmtpReplyException().
The problem originated from way back before 4.904.
The constructor now saves the certificate chain, so the code to retrieve
it again or to perform any additional error checking in
getCertificateChain() is no longer needed.
The constructor now retrieves and saves the private key so that any
resulting errors are detected sooner.
Methods that retrieve the alias perform checks to assure that the client
cert. satisfies the requested issuers and key type. It's known that
Sendmail may provide a list of issuers in its certificate request, but
then may authenticate against a much larger set of CAs, but then later
reject the mail because the client certificate was not acceptable.
Vetting against the issuer list helps detect such certificate problems
sooner (upon connection) rather than later (upon transmission of mail).
Earlier error detection is necessary so that errors may be presented to
the user during account setup.
Portions of these modifications are based on code from KeyManagerImpl:
https://android.googlesource.com/platform/external/conscrypt/+/master/src/main/java/org/conscrypt/KeyManagerImpl.java
Move KeyChainKeyManager to com.fsck.k9.net.ssl because it is used by
SslHelper and because the class extends X509ExtendedKeyManager, which is
in javax.net.ssl.
The problem can be observed if, when modifying the outgoing server
settings, you change the state of the mRequireLoginView check box,
then change the screen orientation.
This is necessary because the OnCheckChanged listener (which
normally updates the view visibility) is not yet set. (The listeners
are set up after view initialization so that they only fire on
user input.)
It should not be triggered when the instance state is restored
with an AuthType spinner selection of EXTERNAL.
The logic here for the AuthType spinner is similar to that of
the parent commit for the SecurityType spinner.
