I've installed a app called PyDroid 3 from Play Store, but I don't have much space available on my internal memory so i wanted to move the app to SD Card. But Move To SD Card option is available on this app.
Using Android 5.1 on Samsung J2
If it is declared as
internalOnly then the app cannot be moved to external SD (unless root methods / apps are used)
If this attribute is not declared, your application will be installed on the internal storage only and it cannot be moved to the external storage.
Only if it is set to
preferExternal it can be moved to external SD
