java - 通过广播调用服务

Question

您好，我在 kontak sdk 中有一个信标扫描仪服务，但是当用户打开和关闭蓝牙时，我需要从广播接收开始扫描 我的广播

public class Bluetooth_Reciver extends BroadcastReceiver {
private static final String TAG = "Bluetooth_Reciver";
@Override
public void onReceive(Context context, Intent intent) {
    try {
        final String action = intent.getAction();
        if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED)) {
            final int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE,
                    BluetoothAdapter.ERROR);
            switch (state) {
                case BluetoothAdapter.STATE_TURNING_OFF:
                    Intent intent1 = new Intent();
                    intent1.setAction("com.mypackage.name.Beacons.BeaconService");
                    intent1.setPackage("com.mypackage.name.Beacons");
                    context.stopService(intent1);
                    break;
                case BluetoothAdapter.STATE_ON:
                    Intent i = new Intent();
                    i.setAction("com.mypackage.name.Beacons.BeaconService");
                    i.setPackage("com.mypackage.name.Beacons");
                    context.startService(i);

                    break;
            }
        }

    }catch (Exception e){
        e.printStackTrace();
    }
}

}

list 服务

        <service android:name=".Beacons.BeaconService" ></service>

当用户打开蓝牙时进入广播并工作但服务未初始化..

Answer 1

这就是我从接收器启动服务的方式:

@Override
public void onReceive(Context context, Intent intent) {
    // TODO: This method is called when the BroadcastReceiver is receiving
    // an Intent broadcast.
    context.startService(new Intent(context, MyService.class));
}

而且效果非常完美。
