Android development path 02 (talking about BroadcastReceiver) and broadcastreceiver I. BroadcastReceiver is used to receive broadcasts from systems and applications. The application is as follows: 1.

When the network status changes, the system generates a broadcast. After

its own Dalvik virtual machine strength. Compared to the Java Virtual machine, Dalvik is specifically tailored for mobile set-up, which is optimized for mobile memory CPU performance.(The mechanism of ART is different from Dalvik.) Under Dalvik, every time the application is run, the bytecode needs to be converted to machine code via an instant compiler, which slows down the efficiency of the application, while in the art environment, when the application is first installed, bytecode is pre-com

In a recent project, you need to find the URI of the image through the absolute path of the image, delete the image, and summarize the method for obtaining the URI.
