I basically have the same question as here :
How to find CPU load of any Android device programmatically
This question was discussed here with many comments but none is anywhere near the solution.
I have tried them all, implemented and tried them on mu Android device. None give the information like on this screenshot, the CPU name (qualcomm , mediatek...) , cpu clock speed, gpu information too...
Did anyone found a solution to this ? How does the cpu-z team do it ?
