This is a simple example of Aspect Oriented Programming in Android as part of a blog post I have written. The idea was to measure how long takes a method to be executed, so based on annotations, a Metrics aspect was created for making easy to trace a method execution (you can take a look at the 'gintonic' folder). I wrote an article about Aspect Oriented Development in Android here:

After developing this I realized Jake Wharton has already created a very useful library called Hugo (I refactored my code to look like this amazing library but mine is kind of a more primitive version, although as an example works fine :)).

The idea is simple, you just add @DebugTrace to any method and in the logcat you will see something like this:

Gintonic --> onMeasure --> [10ms]

Here are some useful Gradle/adb commands for executing this example:

• ./gradlew clean build - Build the entire example.
• ./gradlew installDebug - Install the debug apk in the current connected device.
• adb shell am start -n android10.org.viewgroupperformance/org.android10.viewgroupperformance.activity.MainActivity - Start the Main Activity of the example.
