Sorry, after I tried, I still failed.
If you can not install directly according to the 790 version, the prompt parsing package error, this should be the APK directly does not support the android4.1.1 system, the 709 version can be installed normally, but once the playback starts, the player will crash immediately, can not be used normally, 704 can Normal use.
I want to declare my device again: SONY NWZ-ZX1 Professional Player Not SONY Xperia XZ1
The Android version is 4.1.1.
In addition, I would like to ask, as a professional player SONY NWZ-ZX1, the machine itself supports HI-Res, but Poweramp can not open the relevant settings of HI-res, is there any special optimization for this device?
