Gets the last account that the user signed in with.

Returns a GoogleSignInAccount present in the result data for the associated Activity started via GoogleSignInClient.getSignInIntent().

A sample usage:

try {
   // As documented, we return a completed Task in this case and it's safe to directly call
   // getResult(Class<ExceptionType>) here (without need to worry about IllegalStateException).
   GoogleSignIn.getSignedInAccountFromIntent(intent).getResult(ApiException.class);
 } catch (ApiException apiException) {
   Log.wtf(TAG, "Unexpected error parsing sign-in result");
 }

A sample usage:

 // Check for your incrementally authed features:
 if (!GoogleSignIn.hasPermissions(
   GoogleSignIn.getLastSignedInAccount(this), Drive.SCOPE_APPFOLDER)) {
   requestPermission(Drive.SCOPE_APPFOLDER, RC_REQUEST_DRIVE_AND_CONTINUE_FILE_CREATION);
 } else {
   createDriveFile();
 }

 void createDriveFile() {
    Drive.getDriveResourceClient(this, GoogleSignIn.getLastSignedInAccount(this))
        .createFile(appFolderRoot, changeSet, newContents);
    ...
 }

 private void requestPermission(Scope scope, String requestCode) {
   GoogleSignIn.requestPermissions(
       this,
       requestCode,
       GoogleSignIn.getLastSignedInAccount(),
       scope);
 }
 // ...
 @Override
 void onActivityResult(int requestCode, int resultCode, Intent intent) {
   if (resultCode == Activity.RESULT_OK) {
     if (RC_REQUEST_DRIVE_AND_CONTINUE_FILE_CREATION == requestCode) {
