In both Streamline and Graphics Analyzer, when connecting to an Android device, the target device would briefly appear in the devices list, but then disappear, showing "No targets have been detected" (Streamline) / "Unable to validate ADB" (GA), and reappear after a few seconds - the cycle repeats, as if I have a loose connection.
In very rare occasions, the app was able to get through the "flashing" phase and show me the app to capture, and if I start capture then, the app works just fine afterwards, with constant output and no disconnections. However, it's nowhere near reliable.
I've tried different USB ports, cables and even target devices, but all of them exhibit the same behaviour. Also note that my ADB setup is fine all this time, as I can "adb shell" to my device and it stays connected.
Product: DS 2021.0 Gold Evaluation, with Streamline 7.6 / Graphics Analyzer 5.8
OS: Windows 10 64-bit
Hi Peter,
Supposedly nothing is using ADB concurrently - since you've mentioned it, I did "adb kill-server" prior to launching to be sure, yet with the latest platform-tools, the above symptoms still show. Furthermore, I didn't have to kill-server with platform-tools r28.0.1, it "just works".
Yes I already manually appointed adb paths during earlier tests, either to the latest or to r28.0.1.
Thanks,
Andy
Thanks Andy.
We're investigating and will let you know when we have something.
Cheers, Pete
Hi Andy
We typically test Streamline against r30 so it is surprising you are having this issue. Additionally, I have tested with r31 platform tools and cannot reproduce this issue. Are you sure there are no other users of adb running at the same time (for example Android Studio).Assuming there are not, can you please provide us with the log output from the following steps. These commands will allow us to report the output from each 'adb' command that Streamline issues, hopefully to identify the specific command that is failing:From windows command prompt:
CD C:\Program Files\Arm\Development Studio 2021.0\bin\ (or whatever the install path is + bin) SET DEVTEST_LOG_TO_SCREEN=true streamline.exe -consolelog > %USERPROFILE%\streamline.log (or some other writable location)
Hi Ben,
Log here (too large for forum attachment).
While this log was captured...
Is there a similar logging method for Graphics Analyzer? The symptoms are more pronounced there (e.g. app often stops responding).
Side note: I just discovered ARM Mobile Studio which is free and comes with SL/GA as well (sharing the same problem). However, as MS Starter Edition doesn't come with support, I'll stick to using DS for debugging until the trial runs out.
Thanks,Andy
Hi Ben, any discoveries from that log?
Hi Andy, Thanks for the log. There's nothing particularly wrong in the log you sent, but it does look like it is doing eveything twice, which is unexpected. There were some changes in the package scanning and device enumeration in the very latest version of Streamline (version 7.7) which is available in Mobile Studio 2021.1 and will be released in the next version of Arm DS as well. Can you please give MS Starter Edition a quick try and see if you see the same results in the latest edition or not.
Hi Ben, same thing with MS. My DS trial license is expiring soon so I'll have to use MS to try out future advice from here on out.
