Per the Creating Immersions documentation one can Specify android:immersive="true" for your <activity> element to give immersions focus after a screen sleeps and wakes up.
From my experience, this returns you to the last activity that the user was on before Glass went to sleep, for example: If the user went to ActivityA, then ActivityB, then ActivityC, and Glass goes to sleep, when the user wakes Glass up they're returned to ActivityC.
Is there a way to have the user returned to a specific activity? Say, the same scenario happens as described above, but when Glass wakes up the user is returned to ActivityA?
Thanks in advance, Cole
Create a member boolean variable like mInitialLaunch in Activity B and C. In onCreate of Activity B and C set mInitialLaunch to true.
At the end of onResume in B and C, set mInitialLaunch to false.
At the start of onResume in B and C, check mInitialLaunch and if it is false (meaning only onResume was called) launch Activity A.
This is a way to game the Activity LifeCycle to do what you want.
If you want more information about the Activity LifeCycle and Glass ...
This is an open source project I created to help students learning Glass and Android basics get up to speed on the Activity LifeCycle:
