I'va captured that frame using a nexus 5 and opened it without any warning or error, but the time for the draw calls are all missing. There's a message saying No metric available where I should be able to select GPU time. Here's a example frame on geometry dash:
Unfortunately, the Nexus 5 has a Snapdragon processor, which GPA does not currently support (which is why metrics are not showing up). GPA only supports Android devices with Intel chips inside. If you have another Android device that has an Intel chip, we can help you get that up and running.
