For system elements, such as desktop icons, notification bar, and so on, because ROM, launcher difference is too large, it is recommended to stay away from these parts, do not engage, otherwise the cost may be greater than the benefit. adaptation is hard work, separating changes, isolating changes, and using design solutions more clearly than adding if statements

In Android development, how can we effectively detect memory usage and Memory leakage?
Three methods are introduced here:
1. Program Log information
During garbage collection, the program prints a Log information logcat window. For example:

writes, because the data source component may be silently reclaimed by the system, resulting in the loss of non-persisted write data. Therefore, in the implementation of the data source component, the Write optimization strategy should be referred to the upper call to implement, or the underlying data store to deal with.Once the data source component is constructed, it remains in a long-running state until the process in which it resides is reclaimed by the system. So don't cache too much data
