How to print an array in Android Log output (Logcat)

If you need to dump the contents of an array to the Android Log (Logcat) output, I can confirm that this approach works, at least with simple arrays of integers and strings that know how to print themselves:

Log.i("MyAndroidClass", Arrays.toString(arr));

If you’re trying to print more complicated arrays of custom objects you’ll probably need to implement good toString methods on those objects, and then this technique should work.
