[java] How do I delete files programmatically on Android?

I'm on 4.4.2, trying to delete a file (image) via uri. Here's my code:

File file = new File(uri.getPath());
boolean deleted = file.delete();
      boolean deleted2 = file.getCanonicalFile().delete();
           boolean deleted3 = getApplicationContext().deleteFile(file.getName());

Right now, none of these delete functions is actually deleting the file. I also have this in my AndroidManifest.xml:

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

This question is related to java android file uri delete-file

The answer is

Try this one. It is working for me.

handler.postDelayed(new Runnable() {
    public void run() {
        // Set up the projection (we only need the ID)
        String[] projection = { MediaStore.Images.Media._ID };

        // Match on the file path
        String selection = MediaStore.Images.Media.DATA + " = ?";
        String[] selectionArgs = new String[] { imageFile.getAbsolutePath() };

        // Query for the ID of the media matching the file path
        Uri queryUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
        ContentResolver contentResolver = getActivity().getContentResolver();
        Cursor c = contentResolver.query(queryUri, projection, selection, selectionArgs, null);

        if (c != null) {
            if (c.moveToFirst()) {
                // We found the ID. Deleting the item via the content provider will also remove the file
                long id = c.getLong(c.getColumnIndexOrThrow(MediaStore.Images.Media._ID));
                Uri deleteUri = ContentUris.withAppendedId(queryUri, id);
                contentResolver.delete(deleteUri, null, null);
            } else {
                // File not found in media store DB
}, 5000);

File file=new File(getFilePath(imageUri.getValue()));
boolean b= file.delete();

not working in my case. The issue has been resolved by using below code-

ContentResolver contentResolver = getContentResolver ();
contentResolver.delete (uriDelete,null ,null );

first call the intent

Intent intenta = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
startActivityForResult(intenta, 42);

then call the result

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case 42:
            if (resultCode == Activity.RESULT_OK) {
                Uri sdCardUri = data.getData();
                DocumentFile pickedDir = DocumentFile.fromTreeUri(this, sdCardUri);
                for (DocumentFile file : pickedDir.listFiles()) {
                    String pp = file.getName();
                    String ppdf="";
                File pathFile = new File(String.valueOf(sdCardUri));

I see you've found your answer, however it didn't work for me. Delete kept returning false, so I tried the following and it worked (For anybody else for whom the chosen answer didn't work):

System.out.println(new File(path).getAbsoluteFile().delete());

The System out can be ignored obviously, I put it for convenience of confirming the deletion.

I tested this code on Nougat emulator and it worked:

In manifest add:



Create empty xml folder in res folder and past in the provider_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
 <paths xmlns:android="http://schemas.android.com/apk/res/android">
   <external-path name="external_files" path="."/>

Then put the next snippet into your code (for instance fragment):

File photoLcl = new File(homeDirectory + "/" + fileNameLcl);
Uri imageUriLcl = FileProvider.getUriForFile(getActivity(), 
  getActivity().getApplicationContext().getPackageName() +
    ".provider", photoLcl);
ContentResolver contentResolver = getActivity().getContentResolver();
contentResolver.delete(imageUriLcl, null, null);
