PC :
Mali Graphics Debugger from Arm Ltd.
Version: 5.1.0.8a0102de
i follow the step of documents about using mgd on unroot-devices
my phone is huawei P20 Mate 20 V10 and Oppo r15 , they are all android8.0+
when i startup the my app(with System.load libmgd.so )，MGD on PC do not trace anything
I check the log on phone , they show:
···
E/mgd_interceptor: (8352): SocketMessagePort: Unable to connect socket: Unable to connect socket: errno = 13W/mgd_interceptor: (8352): GatorConnection: Not connected to gatord, the application will run normally but Streamline will not collect annotations. To collect annotations, please verify you are running gatord 5.22 or later and that SELinux is disabled.E/mgd_interceptor: (8352): Interceptor: MGD failed to read the process whitelist file: No reason provided. (Does the file exist & have correct permissions?)W/mgd_interceptor: (8352): Interceptor: MGD_HEADLESS_CONFIG_FILE not specified, falling back to '/sdcard/mgd-headless.conf'E/mgd_interceptor: (8352): Interceptor: Headless config file specified was not foundE/mgd_interceptor: (8352): Interceptor: Unable to create message port - using null
anyone has idea to fix the socket permission error ?
Hi Ho2018, Sorry for the slow reply on this one - this question got missed in our regular review of unanswered questions.Applications compiled with android:targetSdkLevel >= 26 for Android 8.0 upwards will use a more restrictive security sandbox which blocks our interceptor's socket creation. We don't yet have a shipping fix, but as an interim workaround compile you Application with a manifest setting targetSdkLevel to 25 or lower.
Kind regards, Pete
Just one update that we have an improved workaround which does allow tracing of applications with targetSdkLevel 26 and higher. Details can be found here:
