We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I have a PrintWriter object named fileOut
which I initialize with createWriter("testfile.txt")
. I then print to it, flush and close it.
It will not compile, repeatedly giving me two of these errors:
check = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Manifest.permission.READ_EXTERNAL_STORAGE cannot be resolved
I have both READ_EXTERNAL_STORAGE
and WRITE_EXTERNAL_STORAGE
enabled properly.
Anyone experience this before?

if platform >22 && android mode < 4 try:
check = ContextCompat.checkSelfPermission(this.getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)
(if check== false then ContextCompat.requestPermissions(getActivity().....)

How do you keep track of API > 22? Is it possible to access what API a phone can handle on real time? One strategy I would consider is to adjust the min API in the manifest. This will limit the access of the app from other devices with older APIs. Is that a good idea? If I can access the API version on the phone, could I implement a way so the code works for API<22 and API>22?

@kfrajer=== BUILD is your friend::
Build.VERSION.SDK_INT returns API level used by the phone BUILD.VERSION.RELEASE returns the OS system: 4.4.4 for kitKat etc
--As for the Manifest, yes, you can and must adjust the MinSDK in it; if you don't default value used is 1....So it is a good idea -
-- As for coding for API-- && API++ yes, you can do that: globally appCompatV4 or V7 or... is made for that; yet in many cases you have only to have a look to the API and what changes are happened: so using (Build.) (once!!!!) you can write as i have done: if...use this method){else..... use this one...
@akenaton Thxs.
