Manifest:

</manifest>

Permission code in Mainactivity.java

checkAndRequestPermissions(); //called in oncreate() of activity


   private boolean checkAndRequestPermissions() {
        try {
            int permissionWriteEXTERNALSTORAGE = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
            int PermissionCamera = ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA);


            List<String> listPermissionsNeeded = new ArrayList<>();

            if (permissionWriteEXTERNALSTORAGE != PackageManager.PERMISSION_GRANTED) {
                listPermissionsNeeded.add(android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
            }
            if (PermissionCamera != PackageManager.PERMISSION_GRANTED) {
                listPermissionsNeeded.add(android.Manifest.permission.CAMERA);
            }
            if (!listPermissionsNeeded.isEmpty()) {
                ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), 1);
                return false;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return true;
    }

Thanks in advance, for perfect solution.

Answer 1

finally i got solution for above problem of Screen Overlay Detected by removing below code which i was using for testing memory usage in app:

final Runtime runtime = Runtime.getRuntime();
        final long usedMemInMB=(runtime.totalMemory() - runtime.freeMemory()) / 1048576L;
        final long maxHeapSizeInMB=runtime.maxMemory() / 1048576L;
        final long availHeapSizeInMB = maxHeapSizeInMB - usedMemInMB;
        Toast.makeText(getApplicationContext(),String.valueOf(usedMemInMB+"  "+ maxHeapSizeInMB+" "+ availHeapSizeInMB), Toast.LENGTH_LONG).show();

Thanks for everyone support!
