You can use Arrays.toString

Log.d("this is my array", "arr: " + Arrays.toString(arr)); // or System.out.println("arr: " + Arrays.toString(arr)); 

Or, if your array is multidimensional, use Arrays.deepToString()

String[][] x = new String[][] {     new String[] { "foo", "bar" },     new String[] { "bazz" } }; Log.d("this is my deep array", "deep arr: " + Arrays.deepToString(x)); // or System.out.println("deep arr: " + Arrays.deepToString(x)); // will output: [[foo, bar], [bazz]]
