[SOLVED] Delete file in data directory

Delete file in data directory

I have the same problem like in Android, delete files in my data directory?

But it is not working for me.

String sourcefile = getFilesDir().toString() + "/aaa.jpk";
File file = new File(sourcefile);
file.delete();

That should be the easiest way to delete that file but somehow I can't do it. The permissions are added to android manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

so that not the problem. That string is leads me to file :

data/data/com.example.program/files/aaa.jpk

Where is my problem actually? I can't figure that out.

Code for downloading file:

 dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
 Uri resource = Uri.parse("http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml");
 DownloadManager.Request request = new DownloadManager.Request(resource);
 request.setAllowedNetworkTypes(Request.NETWORK_MOBILE | Request.NETWORK_WIFI);
 request.setDestinationInExternalFilesDir(getApplicationContext(), null, "aaa");
 request.setAllowedOverRoaming(false);
 request.setTitle("a.xml");

 dm.enqueue(request);

Solution

Never use concatenation to create a path. Use File file=new File(getFilesDir(), "aaa.jpk"); and see if that helps. Note that your permissions are irrelevant here, as you are working with internal storage, not external storage.
