I use Eclipse and Android Studio, both use the same avd manager
I already tried adb root -> adb remount, adb shell -> su -> mount -o rw,remount [-t ext4] [/dev/block/vda] /system all these commands output remount failed: Permission denied or mount: Permission denied. After that I install FramaRoot and KingoRoot for rooting my emulator, but FramaRoot crashed and KingoRoot show errors. Now I have no idea what to try for mounting /system to rw. In the end I want to push modified file hosts to /system/etc
Android 4.2.2, Eclipse 4.6.2, Android Studio 2.3, Host OS: Linux Mint 18.1
I was gave advice: android sdk have program "emulator" in sdk/tools all what you need is run your avd like .../sdk/tools/emulator -writable-system -avd avdsName' then use adb remount. Tricky method in some way.
