Record tablet's screen AND audio

Question

I\'ve been wondering, after trying this command on my Nexus 7:

adb shell screenrecord /sdcard/demo.mp4

Is there a way to record the screen

Answer 1

Jeff's answer seems to be the only way you can use through adb. But that force you to do some work (merge video + audio).

Another way is to directly use an android app:

• SCR Screen Recorder - official website - XDA - short review
• Mobizen for SAMSUNG - google play
• RecMe - google play

SCR Screen Recorder:

• pros :
  • the only app that truly works for recording video + internal audio with all devices
• cons:
  • banned from google play because of SELinux policy (see XDA - Google Play ban and "Dangerous app" warning)
  • require root for recording internal audio

Mobizen for SAMSUNG:

• pros
  • on google play store
• cons
  • only the samsung version works for recording internal audio, the general or LG, XIAOMI version can't record internal audio
  • still a beta feature
  • require root for recording internal audio

RecMe:

• pros
  • on google play store
• cons
  • internal audio recording doesn't works on most devices
  • require root for recording internal audio

Personally I tried a lot of apps and the only working for me is SCR Screen Recorder.

PS : all these apps works without root if not using internal audio.
