Thanks Taifun and Peep Prants,
Yes , My phone is not rooted . So I didnt get the logs
And when I tried it in pc, It was saying Waiting for device. The reason is i hadnt set on USB Debugging . Developer option is hidden on my phone MI3 running on 4.4.4. Have to tap MIUI version several times to unhide it in my phone not the build number as in most of the phones. So now the problem is solved.
I got the code for google cardboard app
I/ActivityManager( 1150): Start proc com.google.samples.apps.cardboarddemo for a
ctivity com.google.samples.apps.cardboarddemo/com.google.vr.cardboard.paperscope
.carton.Home2D: pid=21578 uid=10133 gids={50133, 1028, 1015, 3003}
Now I can do it for all the apps I want to. Feeling very happy about that. Thanks for the support.
