If we want to get battery information for a cell phone, it can be broadcast. The system sends a broadcast when the battery level of the phone is changed. The specific code is as follows// Register intentfilter.addaction (intent.action_battery_changed); Mcontext.registerreceiver (MHallReceiver, IntentFilter ); // Broadcast processing intent.getaction (). Equals (intent.action_battery_changed) { int level

Step 1: Prepare the iphone, as shown in the following figure, and then prepare a rose-sized iphone.-As shown in the figure, we use a dedicated starter.-When we cut down the following screws, we can find a suction cup to suck up the back.
