Problem with sync FB contacts to android's address book.

Hi. I am new here.
I have problem with sync contacts from Facebook on my smartfon with Android 4.4.4 (Samsung Galaxy Core Prime LTE). It was working about 1 or 2 weeks ago, now doesn't work. Android doesn't download even 1 contacts from Facebook to his address book.
I logged out from Facebook application, deleted account Facebook from account in address book. Then added Facebook account again, logged in in Facebook application. Switch on sync all contacts and setup contacts to show for google account and Facebook account. Sync was completed and nothing was downloaded.
I don't know how can I fix this up.

PS: Facebook application was reinstalled, doesn't help..
PS2: application such sync.me doesn't download any FB contacts , too.

Nexus 7 2013 WiFi - WiFi won't turn on after Marshmallow upgrade - bad Mac Address

Just sideloaded the Mashmallow update from 5.1.1 to 6.0 (downloaded from Google) and the update seemed to go normally - most things work as normal. But the WiFi wouldn't turn on, and it's mac address reports as 02:00:00:00:00:00. That address I know was an issue in the M Preview as a fake address.

I didn't want to hard reset it but in the end relented and loaded a clean new version of 6.0 from Google. When it restarts the second thing it wants to do, after selecting a language, is start the WiFi so it can log on. Of course WiFI won't start, and I can't "skip" so it's stuck. I tried Bad_Boyz fromXDA, and then going back to 5.1.1, and now forward again to 6.0 - same result. I suspect the WiFi mac address has been cleared. I found a little help that if I shell into the tablet, and write the mac address into /persist/wifi/.macaddr I might move forward. I know how to do this, but I can't shell in with adb. I can talk over USB, and run fastboot. When I connect via USB the Nexus mounts (sort of - the storage folder isn't shown when the tablet is at the "Select WiFi network" stage of setup)

When I run "adb devices" - I can't see any, even though I can "fastboot reboot recovery" and the like. I'm sure bluetooth (mac address) is broken too, but I"ll fix that later.

Does anyone have any idea how I can encourage adb to talk, so that I can "adb shell"?

Sending Email from My Email address

I am a beginner to Android development. I just started making an Android app in which there multiple EditText fields where user would fill in some data and then click a button. On button click I need to send an email using my email address which is GMail (NOT THE END USER'S). So, I searched on internet for this, found a way by using "JavaMail" API. But I had to "Enable access to insecure apps", in Google settings of my GMail address for it to work. I don't want my end users to grant access to their email accounts.
I searched for OAuth2 implementations but all were there for using the end user's account to send email.

Help me to find a way to send email from my own GMail account without enabling insecure apps for my GMail.

If you need any more information let me know.

Can anyone tell me how to change Mac address in RedMi 2 Prime?

I want to change Mac address of RedMi 2 Prime mobile as my company Wi-Fi access is restricted to few Mac addresses only.

I rooted my mobile and tried BusyBox and Terminal...it didn't work!

This YouTube video suggests to edit the file .mac.cob in /efs/wifi..but this mobiles doesn't have the folder efs in Device...!!

This does have a folder wifi in Device/etc...and it has a file WCNSS_qcom_cfg.ini.It has Mac in Hex format.
The code for WCNSS_qcom_cfg.ini is available in Google Source


Lines 34 to 39
# Assigned MAC Addresses - This will be used until NV items are in place
# Each byte of MAC address is represented in Hex format as XX
Intf0MacAddress=000AF58989FF
Intf1MacAddress=000AF58989FE
Intf2MacAddress=000AF58989FD
Intf3MacAddress=000AF58989FC


I tried This tutorial also..but didn't work :(
Can anyone tell me how to change Mac..it would be appreciated

Thanks in advance
