code cleaning:

- lambda expressions, method references,
- multi catches,
- remove unnecessary keywords (public keyword on interface method signatures, static on interfaces or enums, final on private method signatures),
- == false expressions,
- diamond type (<>) expressions,
- replace StringBuffer with StringBuilder for local variables used by a single thread,
- replace Arrays.asList with Collections.singletonList whenever applicable,
- inline variable returns (whenever the variable name's meaning is not important to understand the code),
- replace some chains of if/else if/... with switch/case,
- break append(a + b) into append(a).append(b) for StringBuilder objects,
- unused import statements,
- reduce log TAGs to 23 characters,
- MaterialDialog callback deprecated,
- ActionBarActivity for AppCompatActivity,
