如何在按下电源按钮时执行我的应用程序的某些功能？
问题描述：
我想在按两次电源按钮时发送一封电子邮件？我已经尝试了很多代码，但目前还没有任何代码正在工作。任何人都可以帮忙吗？如何在按下电源按钮时执行我的应用程序的某些功能？
这是我服务类
public class UpdateService extends Service {
BroadcastReceiver mReceiver;
int counter=0;
@Override
public void onCreate() {
super.onCreate();
// register receiver that handles screen on and screen off logic
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
mReceiver = new Receiver();
registerReceiver(mReceiver, filter);
}
@Override
public void onDestroy() {
unregisterReceiver(mReceiver);
Log.i("onDestroy Reciever", "Called");
super.onDestroy();
}
@Override
public void onStart(Intent intent, int startId) {
boolean screenOn = intent.getBooleanExtra("screen_state", false);
if (!screenOn) {
counter += 1;
Log.i("screenON *****************", "Called");
Toast.makeText(getApplicationContext(), "Awake" + counter, Toast.LENGTH_LONG)
.show();
} else {
counter += 1;
Log.i("screenOFF ******************", "Called");
Toast.makeText(this, "slept" + counter, Toast.LENGTH_SHORT).show();
}
if (counter >= 4) {
Log.e("counter is -->", "" + counter);
counter = 0;
Log.e("counter is after clearance -->", "" + counter);
Log.e("************-***********", "Boooyah");
Toast.makeText(this, "Booyaaaha !!!!!!!!!!!!!!!!", Toast.LENGTH_SHORT).show();
Intent email = new Intent(Intent.ACTION_SEND);
email.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"});
email.putExtra(Intent.EXTRA_SUBJECT, "TFS");
email.putExtra(Intent.EXTRA_TEXT, "This is the sample Message of my email");
email.setType("email/rfc822");
startActivity(Intent.createChooser(email, "Send Mail Via"));
email.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
email.addFlags(Intent.FLAG_FROM_BACKGROUND);
startActivity(email);
}
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
}而这个小家伙是接收
public class Receiver extends BroadcastReceiver {
private boolean screenOff;
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
screenOff = true;
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
screenOff = false;
}
Intent i = new Intent(context, UpdateService.class);
i.putExtra("screen_state", screenOff);
context.startService(i);
}
}清单
