Android 每分钟广播

Android系统每分钟会发广播：如8:51:59 调到 8:52:00时就会发送广播

注册广播接收器：（注意：注册不能在Menifest.xml中注册）

IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_TIME_TICK);
registerReceiver(receiver, filter);

移除接收器：

unregisterReceiver(receiver);

BroadcastReceiver receiver = new BroadcastReceiver() {
    private String currentDate = null;
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals(Intent.ACTION_TIME_TICK))

	{

	    //.....处理逻辑

	}

    }
};
