app:lint error with LongLogTag

Current configuration supposes to have server laptop that runs time sync algorithm

The list of parameters is here: https://github.com/azaat/softwaresync-imu/blob/d0114265578cc12647cdf23e7a665fae79864654/app/src/main/res/raw/pixel1_phaseconfig.json

Phase alignment might require additional tuning since it doesn't always converge even in 25 steps on some smartphones (may need to have a look at overheadNs for starters)

For now, that parameter is hardcoded, but can be easily calculated from the stream timestamps as average value

Support meaningful error handling on server (for instance, so that it continues working after wrong files have been sent and notifies user about the error), return responses with messages for user

Preferences to be created:

• Phase alignment configuration values
• Choice between hotspot smartphone being leader or manual leader IP selection
• Sensor recording period
• Preview resolution
• Formats of saved frames

WIP: More info is expected from the logs

https://github.com/azaat/softwaresync-imu/blob/68951fac0dc79a32eae3e87f706514133c496e22/app/src/main/java/com/googleresearch/capturesync/MainActivity.java#L513 -- here camera ids can be switched

Iterations:

• Add to config
• Move to GUI settings

Now only two smartphones are supported

• Create a basic C++ class, which has the method taking two IMU data files and returning some constant number

• Integrate it instead of doGyroSyncOnServer in ImuTimeSync.java

• This could be useful to test out integration of C++ methods in Android project (to make sure there will be no problems with the real algo, also to be able to reuse this setup with real algorithm)
