I'm using your small app in my Xperia M2 with 5.1.1 and I like it quite a lot. It's actually the only small app I use.
Still, there are a couple of issues:
- As you probably know already it consumes a bit too much CPU. Even up to 20% monitoring with "busybox top". It's a bit surprising because another monitoring full app in the background consumes far less.
- I am afraid the single core loads monitoring is flat wrong. I compared it in real time with the app I mentioned above and with "busybox pmstat". It also makes little sense because at min frequency it often shows all cores as active
Apart from that it's good. Thanks.
