监听SD卡插拔广播

一：在AndroidManifest.xml文件中一定要在intent-filter中加上，否则无法监听到SD卡插拔广播；

二：如果在Activity里面用代码注册广播，那也一定要加iFilter.addDataScheme("file")。

在AndroidManifest.xml文件中打开权限：

具体监听方法可参考：

eg：

//---------TF卡拔出 广播接收代码------------
	protected TfBroadcastReceiver tfReceiver;
	public class TfBroadcastReceiver extends BroadcastReceiver {
		public TfBroadcastReceiver() {}
		
		@Override
		public void onReceive(Context arg0, Intent intent) {
			Log.i("sxy", "tf卡拔出！！！");
			if(hasTfFile)
			{
				BookSelectActivity.this.setResult(RESULT_CANCELED, null);
				BookSelectActivity.this.finish();
			}
		}
	}
	
	private final static String tf_EJECT = "android.intent.action.MEDIA_EJECT";//tf卡弹出
	//注册TF卡拔出广播
	private void registerTfReceiver()
	{
		Log.i("sxy", "注册TF卡拔出广播");
        hasTfFile = false;
        
		IntentFilter actionFilter = new IntentFilter(tf_EJECT);
		actionFilter.addDataScheme("file");
		tfReceiver = new TfBroadcastReceiver();
	   	registerReceiver(tfReceiver, actionFilter);
	}
	
	//取消TF卡拔出广播的注册
	private void unregisterTfReceiver()
	{
		Log.i("sxy", "取消TF卡拔出广播的注册");
		hasTfFile = false;
		
		unregisterReceiver(tfReceiver);
	}
