Android Debug Playground

Playing with hugo and loglifecycle - annotations, which helps with debugging Android projects.

#hugo

The following code:

@DebugLog
public String getName(String first, String last) {
    SystemClock.sleep(15); // Don't ever really do this!
    return first + " " + last;
}

produces the following logs:

11-16 19:24:34.564    1203-1203/? D/MainActivity﹕ ⇢ getName(first="John", last="Doe")
11-16 19:24:34.580    1203-1203/? D/MainActivity﹕ ⇠ getName [15ms] = "John Doe"

#loglifecycle

The following @LogLifecycle annotation:

@LogLifeCycle
public class MainActivity extends ActionBarActivity {
    //...
}

produces the following logs:

##build.gradle file

Please, take a look at build.gradle file. Sometimes it may happen that project won't be built correctly. In such case, remove the following lines:

apply plugin: 'loglifecycle'
apply plugin: 'hugo'

After that, build project, so it can download dependencies and plugins. When build is complete, add back lines mentioned above, and build project again.
