Android Question Issues in converting code from B4A 5.0 to 8.5.

[Juzer Hussain]

Hi,

I am having hard time converting my code from 5.0 to 8.5.

A simple statement like File.MakeDir(File.DirRootExternal,"MyWardmonitor") is failing

Shall i use GetSafeDirDefaultExternal, I need some visible folder. Looks like permission issue.


Manifest editor has
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE" maxSdkVersion="18" />
and
targetsdkversion is 26

I am using FTP, Webview, Camera, SpeechToText elsewhere will changes will be required there too.

Can someone please point me as to what changes are required.

Thanks
Juzer

Looks like permission issue.

it is.

android.jar / targetSdkVersion / minSdkVersion

Especially RuntimePermissions

You can verify the 'dangerous' permission requests, see the first post here https://www.b4x.com/android/forum/threads/runtime-permissions-android-6-0-permissions.67689/ It is a button 'List Permissions' on the right hand pane in B4A.

Hi eps,

Thanks, I had seen it already, I found implementing Runtime Permission for DirRootExternal little difficult. I would have had to modify too many activities.
As such I changed folder to File.DirInternal which does not require any permission and its working fine.Its safer also as one cannot see data.

I was just wondering why WhatsApp saves data in visible folders, There must be some reason. May be so user can manage storage space.

Hi eps,

Well, those folders hang around when the user removes the app. So perhaps they chose to do it that way so that all account info, history etc would be around if the user re-installed the app at a later time?
