我试图在广播接收器中捕获NFC标签,所以我写了一个简单的BR,在onReceive()中打印“asd”.在清单xml中,它被描述为：

我只收到这个,根本没有印刷品….

01-31 16:37:18.980: ERROR/MediaPlayer(990): setAudioStream called in state 8

01-31 16:37:18.980: ERROR/MediaPlayer(990): error (-38, 0)

01-31 16:37:18.980: ERROR/MediaPlayer(990): start called in state 0

01-31 16:37:18.980: ERROR/MediaPlayer(990): error (-38, 0)

01-31 16:37:18.988: ERROR/MediaPlayer(990): Error (-38,0)

当我使用activity来处理这样的意图时：

android:theme="@android:style/Theme.NoTitleBar">

活动已启动且运行正常,那么我如何才能使其与BroadcastReceiver一起使用？
