Requirement: Android Classic Bluetooth send file, send side support pause operation (Pervert!!!!!) ), also want to continue the breakpoint (more abnormal!!!) ）Approximate implementation:Client sends a fixed length package, the first packet header (fixed length) contains this file identifier (name, total file flow length, etc.), and to handle the socket bufferOverflow problem to prevent drops from appearing.

How can we work around to speed up the Android BLE Transfer progress?

In Android, the listening of Bluetooth device buttons is the same as the listening of general system buttons, but it only processes different keyevents. Here we will talk about the value of the previous and next keyevents sent by bluetooth, Listen to and perform corresponding processing. Public Boolean onkeydown (INT keycode, keyevent event) {Switch (keycode)

If Bluetooth is paired and connected manually, get the connected device:1. Check the connection status:Java code int A2DP = Bluetoothadapter.getprofileconnectionstate (BLUETOOTHPROFILE.A2DP); int headset = bluetoothadapter.getprofileconnectionstate (Bluetoothprofile.headset); int health = bluetoothadapter.getprofileconnectionstate (bluetoothprofile.health); 2, depending on whether there is a connection to obtain the connected d

For the control of GPs on Android, the official provides the relevant APISettings.Secure.setLocationProviderEnabled (Getcontentresolver (), Locationmanager.gps_provider, true);But when we call the Setlocationproviderenabled method, the system throws an exception prompt that requires Android.permission.WRITE_SECURE_SETTINGS permission, even if The same is true for requests that add this permission in Mainfest.
