问题
Hello everybody I have a problem a long time and decided to post , on some devices I can not write anything , this happens especially in mobile phone android(4.1-4.4) that does not have sdcard. Some phones usually work ( especially with android 5.0 ) with or without SDCARD .
My routine is: CHECKS(READ) localStorage ->
IF OK : AUTH AUTOMATIC -> UPDATE LOCALSTORAGE -> GO HOME PAGE.
ELSE : USERS INFORMATION LOGIN AND PASSWORD -> AUTH -> SAVE LOCALSTORAGE -> GO HOME PAGE.
ALREADY TRIED USE : SQLITE AND FILE.
but in some phones especially with android ( 4.1 - 4.4 and without SDCARD ) he finds no content in LocalStorage , so every time the User open the app it needs to inform login and password.
OBS: 1. I checked the AndroidManifest and i HAVE WRITE_EXTERNAL_STORAGE and READ.
- when installed on an emulator android 4.1 without SDCARD , I encounter the following error in CMD " rm failed for -f , Read only file system"
My permissions
- whitelist
- camera
- media-capture
- device
- statusbar
- file
- file-transfer
- imagepicker
- media
- network-information
- file-opener2
- sqlite-storage
- ms-adal
- x-toast
- socialsharing
Thank you in advance
