监听外置sdcard(TF卡)的插拔事件
在编码的过程中需要监听外置sdcard的插拔事件，在AndroidManifest.xml中注册一个静态广播
一定要添加上 <data android:scheme="file" />
<receiver android:name=".SdcardReceiver" android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.MEDIA_MOUNTED" />
<action android:name="android.intent.action.MEDIA_UNMOUNTED" />
<data android:scheme="file" />
</intent-filter>
</receiver>
在java代码中继承 BroadcastReceiver,监听到sdcard的插拔事件，然后做相应的逻辑操作
public class SdcardReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(action.equals(Intent.ACTION_MEDIA_MOUNTED)){
Log.d("tag","sdcard mounted");
}else if(action.equals(Intent.ACTION_MEDIA_UNMOUNTED)){
Log.d("tag","sdcard unmounted");
}
}
}
