How to delete an image from device in Android programmatically?

Question

I am creating an app that lets user select an image from gallery and store it in my DB. I am successful in doing that.

Now I want that selected image to be deleted from phone storage also. how do I do it then?

I might even want to restore it later in users gallery.

This is what I do to get image from gallery.

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) 
{
    switch (requestCode)
    {
        case 42:
            if (resultCode == RESULT_OK)
            {
                Uri uri = data.getData();
                InputStream inputStream = null;
                try
                {
                    inputStream = getBaseContext().getContentResolver().openInputStream(uri);
                    Bitmap bm = BitmapFactory.decodeStream(inputStream);
                    int maxHeight = 1920;
                    int maxWidth = 1920;
                    float scale = Math.min(((float) maxHeight / bm.getWidth()), ((float) maxWidth / bm.getHeight()));
                    Matrix matrix = new Matrix();
                    matrix.postScale(scale, scale);
                    Bitmap bitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true);
                    saveImageToInternalStorage(bitmap, getFileName(uri));
                    bm.recycle();
                    bitmap.recycle();
                    finishActivity(42);
                }
                catch (FileNotFoundException e)
                {
                    e.printStackTrace();
                }
            }
    }
}

This is the Uri path I'm getting

content://com.android.providers.media.documents/document/image%3A5857

my onActivityResult looks like this:

 @Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data)
{
    switch (requestCode)
    {
        case 42:
            if (resultCode == RESULT_OK)
            {
                Uri uri = data.getData();
                InputStream inputStream = null;
                try
                {
                    inputStream = getBaseContext().getContentResolver().openInputStream(uri);
                    Bitmap bm = BitmapFactory.decodeStream(inputStream);
                    int maxHeight = 1920;
                    int maxWidth = 1920;
                    float scale = Math.min(((float) maxHeight / bm.getWidth()), ((float) maxWidth / bm.getHeight()));
                    Matrix matrix = new Matrix();
                    matrix.postScale(scale, scale);
                    Bitmap bitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true);
                    saveImageToInternalStorage(bitmap, getFileName(uri));

                    bm.recycle();
                    bitmap.recycle();
                    finishActivity(42);
                }
                catch (FileNotFoundException e)
                {
                    e.printStackTrace();
                }
            }
    }
}

getContentResolver().delete(uri, null, null); is sufficient for Android Q. — blackapps, Mar 04 '20 at 10:26
requires android.permission.MANAGE_DOCUMENTS, or grantUriPermission() -> Gives me this error and image is not deleted @blackapps — Aaah Aah, Mar 04 '20 at 11:44
Please post an onActivityResult function where you only try to delete the selected image. And tell there which Android version. — blackapps, Mar 04 '20 at 11:46

try this

public static boolean delete(final Context context, final File file) {
      final String where = MediaStore.MediaColumns.DATA + "=?";
       final String[] selectionArgs = new String[] {
            file.getAbsolutePath()
     };
   final ContentResolver contentResolver = context.getContentResolver();
   final Uri filesUri = MediaStore.Files.getContentUri("external");
   contentResolver.delete(filesUri, where, selectionArgs);

if (file.exists()) {

    contentResolver.delete(filesUri, where, selectionArgs);
}
return !file.exists();

}

where do i write this? – Aaah Aah Mar 04 '20 at 11:46
add this into any class and call it where you want like create classs ImageDelete and paste this code and call where you want to delete the image. if you have Uri than convert Uri into file than call it – Amit pandey Mar 04 '20 at 12:24
What is this here ("external") – Aaah Aah Mar 06 '20 at 06:29
its storage location external and internal – Amit pandey Mar 07 '20 at 04:28
