Open Scan with program code

Broadcast implementation, broadcast name: Android.intent.action.SIMSCAN

Example:

Context.sendbroadcast (New Intent ("Android.intent.action.SIMSCAN"));

Description

The scanning light lasts for up to 6 seconds when the scan is turned on via program broadcast, i.e. the laser light of the scanning head is automatically switched off after 6 seconds.

To turn off scanning through program code

Broadcast implementation, broadcast name: Android.intent.action.SIMSCAN

Example:

Context.sendbroadcast (New Intent ("Android.intent.action.SIMSCAN"));

Description

When scanning via program broadcast, the scanning lamp lasts for a maximum of 6 seconds, that is, the laser light of the scanning head will be automatically closed after 6 seconds, then the scanning head can be closed by the above broadcast in 6 seconds.

Get scan results from program code

Broadcast implementation, broadcast name is: Com.sim.action.SIMSCAN, broadcast parameters are: value, parameter type: String

Example:

@Override

protected void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Mreceiver = new Broadcastreceiver () {

@Override

public void OnReceive (context context, Intent Intent) {

To allow other broadcast registrants to be unable to obtain broadcast information, * * * here must be * * *

This.abortbroadcast ();

Get scan results Information here

Final String Scanresult = Intent.getstringextra ("value");

Mtvscanresult.settext (Scanresult);

Mtvscanresult.invalidate ();

}

};

Mfilter = new Intentfilter ("Com.sim.action.SIMSCAN");

When the user gets the data themselves, the broadcast priority is tuned to the highest 1000,*** here must * * *

Mfilter.setpriority (intentfilter.system_high_priority);

}

@Override

protected void Onresume () {

Super.onresume ();

Register a broadcast to get scan results

This.registerreceiver (Mreceiver, Mfilter);

}

@Override

protected void OnPause () {

Log off the broadcast to get scan results

This.unregisterreceiver (Mreceiver);

Super.onpause ();

}

Note: When getting the scan results, it is important to focus on

1) When the program captures the broadcast, it needs to execute:

This.abortbroadcast ();

2) The broadcast receive priority needs to be adjusted to the highest level:

Mfilter.setpriority (intentfilter.system_high_priority);
