Android StrictMode java.lang.Throwable: Explicit termination method 'close' not called

Question

i enable strict mode in my app and it crashed with an error

 boolean DEVELOPER_MODE=true;
        if (DEVELOPER_MODE) {
            StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
                    .detectDiskReads()
                    .detectDiskWrites()
                    .detectAll()   // or .detectAll() for all detectable problems //.detectNetwork()
                    .penaltyLog()
                    .build());
            StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                    .detectLeakedSqlLiteObjects()
                    .detectLeakedClosableObjects()

                    .penaltyDeath()
                    .build());
        }

                thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail(getActivity().getContentResolver(),id,MediaStore.Images.Thumbnails.MICRO_KIND,null);  
            }
            imageCursor.close();

        }

i am closing cursor after loop ending and i am not sure why i am getting this error even i closed cursor after i no longer needed.please guide me to get this fix. I don't have option to disable strict mode in any case so i need to fix this without disabling strict mode.

Full stacks trace of error.

why are you using stric mode if you are "getting path to the uri" ... getting path from uri is **so bad** that you shouldn't worry about strict mode — Selvin, Dec 26 '19 at 04:42
@Selvin i need to fix this with strict mode enable. Any fix for this? — Ritu, Dec 26 '19 at 04:45
it's prolly about internal code of `MediaStore.Images.Thumbnails.getThumbnail` so you cannot fix it but without full stacktrace is hard to guess ... just disable strict mode — Selvin, Dec 26 '19 at 04:49
@Ritu, Did you `recycle` the bitmap after use as It causes of the leak? — ॐ Rakesh Kumar, Dec 26 '19 at 05:13
@RakeshKumar first i need to generate images to recycle them.It's crashed before that — Ritu, Dec 26 '19 at 05:16
@Ritu, update the post with `StrictMode` piece of code you might use — ॐ Rakesh Kumar, Dec 26 '19 at 05:20
@Ritu, Did you call this method before `super.onCreate(savedInstanceState);`? also enable `.penaltyDeath()` to `StrictMode.setVmPolicy` — ॐ Rakesh Kumar, Dec 26 '19 at 05:31
@RakeshKumar I am calling this method after `super.onCreate` and .penaltyDeath will cause app to shutdown even on warning messages — Ritu, Dec 26 '19 at 05:34
@Ritu, put that code before `super.onCreate(savedInstanceState)` will work for you — ॐ Rakesh Kumar, Dec 26 '19 at 05:47
@RakeshKumar Not working same issue even after moving my code before super — Ritu, Dec 26 '19 at 11:46
@Ritu, which version or device you are using, as I haven't found any type of crash on Pie and works fine without `StrictPolicy` — ॐ Rakesh Kumar, Dec 26 '19 at 11:58
@RakeshKumar OP clearly said she can't remove `StrictPolicy` so there will be no crash without `strictpolicy` — androidXP, Dec 26 '19 at 13:52

Without removing your StrictMode you can achieve with the help of Glide library (Image Handling Library). It will not give you any error. I remove bit of your code to make it work without errors.

 private  void getRecentImages (){            
        String[] colums={MediaStore.Images.Media.DATA,MediaStore.Images.Media._ID};
        final String orderBy = MediaStore.Images.Media.DATE_ADDED + " DESC";
        Cursor imageCursor = getActivity().getContentResolver().query(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                colums,
                null,
                null,
                orderBy);
        count=imageCursor.getCount();
        arrayPath=new String[count];
        for (int i = 0; i <count; i++) {
            imageCursor.moveToPosition(i);
            int dataColumnIndex = imageCursor.getColumnIndex(MediaStore.Images.Media.DATA);
            arrayPath[i] = imageCursor.getString(dataColumnIndex);
            //thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail(getActivity().getContentResolver(),id,MediaStore.Images.Thumbnails.MICRO_KIND,null);
        }
        imageCursor.close();

    }

You are getting path of your images in arrayPath so no need to use thumbnail method. so where ever you need to load image just use Glide like this.

        `Glide.with(getActivity()).load(arrayPath[position]).into(youImageView);`
