[Android SDK] Call requires API level 23 (current min is 14)問題的解決

Either check for target >=23 or simply add below line above your method

@TargetApi(Build.VERSION_CODES.M)

For example, If you are checking for storage permissions, then you can refer to this function,

@TargetApi(Build.VERSION_CODES.M)
    public boolean CheckStoragePermission() {
        int permissionCheckRead = ContextCompat.checkSelfPermission(context,
                Manifest.permission.READ_EXTERNAL_STORAGE);
        if (permissionCheckRead != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context,
                    Manifest.permission.READ_EXTERNAL_STORAGE)) {
                // Show an expanation to the user *asynchronously* -- don't block
                // this thread waiting for the user's response! After the user
                // sees the explanation, try again to request the permission.
                ActivityCompat.requestPermissions((Activity) context,
                        new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                        Define.PERMISSION_STORAGE);
            } else {
                // No explanation needed, we can request the permission.

                ActivityCompat.requestPermissions((Activity) context,
                        new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                        Define.PERMISSION_STORAGE);

                // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
                // app-defined int constant. The callback method gets the
                // result of the request.
            }
            return false;
        } else
            return true;
    }
