Examples of use
Reference library
Add common.aar and lib4710.aar to your project.
Add the following repository in the build.gradle android file:
repositories {
flatDir {
Verzeichnisse 'libs'
}
}
Add the dependencies
implementation( name : 'common' , ext : 'aar' )
implementation( name : 'lib4710' , ext : 'aar ' )
!! add permissions
Add
android :sharedUserId ="android.uid.system"
ito the AndroidManifest.xml file.
Note: After adding the system uid, you need to use the system signature (you can contact the developer to
get it) before it can be used normally.
Initialization
After calling init to initialize, set the callback to complete the scan code
// Initialize the sweep port
Scanner . init ( 2 , mContext );
// Set the scan code completion callback (requires after initialization)
Scanner . setDecodeCallback ( new DecodeCallback () {
@Override
public void onComplete ( byte [] data) {
// data is the original data obtained by scanning the code
// Process scan results here
}
});
Monitoring the scan code keys
By default, all physical scan keys always trigger one of the following three groups of transmissions after
being pressed/opened:
static final String ACTION_KEYEVENT_SCAN_F_DOWN = "com.android.action.keyevent.KEYCODE_KEYCODE_SCAN_F_DOWN" ; // Scan code F key DOWN broadcast
static final String ACTION_KEYEVENT_SCAN_F_UP = "com.android.action.keyevent.KEYCODE_KEYCODE_SCAN_F_UP" ; // Scan code F key UP broadcast
static final String ACTION_KEYEVENT_SCAN_L_DOWN = "com.android.action.keyevent.KEYCODE_KEYCODE_SCAN_L_DOWN" ; // Scan code L key DOWN broadcast
static final String ACTION_KEYEVENT_SCAN_L_UP = "com.android.action.keyevent.KEYCODE_KEYCODE_SCAN_L_UP" ; // Scan code L key UP broadcast
static final String ACTION_KEYEVENT_SCAN_R_DOWN = "com.android.action.keyevent.KEYCODE_KEYCODE_SCAN_R_DOWN" ; // Scan code R key DOWN broadcast
static final String ACTION_KEYEVENT_SCAN_R_UP = "com.android.action.keyevent.KEYCODE_KEYCODE_SCAN_R_UP" ; // Scan code R key UP broadcast
You can monitor these three broadcast groups of transmissions, start scanning the code when the down
transmission is triggered, and stop scanning the code when the up transmission is triggered.
You can monitor these three broadcast groups to determine when one of the buttons has been pressed to
