8. Project Svelte

Android N removes the following broadcasts in order to help optimize both memory use and power consumption.

• ConnectivityManager.CONNECTIVITY_ACTION
• Camera.ACTION_NEW_VIDEO
• Camera.ACTION_NEW_PICTURE

Normally any application can monitor this broadcast about connectivity change, new picture, new video. However, when a single change occurs in network connectivity, then all the apps tries to do their work at the same time. By removing these broadcasts it will help device performance and user experience.

Suggested way of handling these events is:

Job Scheduler

JobScheduler.Builder.addTriggerContentUri();
