Android SD card Mount judgment

Android differentiate SD does the card have a method that is now mounted? This article describes an android -differentiated SD card that is not currently mounted by the method that touches the Android listening method Broadcastreceiver The use of Tips , with a certain reference to learning value , the needs of friends can see the next

This article is an example of how Android differentiates an SD card from being mounted. Now with the same wheat Academy's Android development teacher to see:

Supply a listening method broadcastreceiver set Intentfilter to:

intent.action_media_mounted
Intent.action_media_eject
Intent.action_media_removed

Then the public void OnReceive (Contextcontext, Intent Intent) ends your starting logic startactivity

Privatefinalbroadcastreceiver Broadcastrec =newbroadcastreceiver () { @Override publicvoidonreceive (context context, Intent Intent) { if (intent.getaction (). Equals ("Android.intent.action.MEDIA_MOUNTED")) //SD The card is now mounted successfully { ImagePath = android.os.Environment.getExternalStorageDirectory ();// of your SD Card Path }else if (Intent.getaction (). Equals ("Android.intent.action.MEDIA_REMOVED") // various non-mounted conditions || Intent.getaction (). Equals ("Android.intent.action.ACTION_MEDIA_UNMOUNTED") || Intent.getaction (). Equals ("Android.intent.action.ACTION_MEDIA_BAD_REMOVAL")) { ImagePath = Android.os.Environment.getDataDirectory ();// your local path } } }; // Select the action you want to monitor in the intentfilter intentfilter intentfilter =newintentfilter (intent.action_media_mounted); intentfilter.addaction (intent.action_media_unmounted); intentfilter.addaction (intent.action_media_removed); //intentfilter.addaction (intent.action_media_shared); intentfilter.addaction (intent.action_media_bad_removal); //intentfilter.addaction (intent.action_media_scanner_started); //intentfilter.addaction (intent.action_media_scanner_finished); intentfilter.adddatascheme ("file"); registerreceiver (Broadcastrec, intentfilter);// Register listener function unregisterreceiver (BROADCASTREC);// Use the Logout broadcast listener function

Hopefully this article will help with our Android programming.
