Pushing files in android /system/app folder

Pushing files in android /system/app folder(help got from this link)

Steps to follow

1. Launch the emulator from the command line so that system folder should have free space.       emulator -avd test3 -partition-size 512                                              The emulator binary should be in  tools/ directory within your SDK link 
2. Start the adb shell (command line for emulator) adb binary is in platform-tools                            adb shell (use df command to see the used and free space on partitions)
3. Remount the system directory                                                                                                   mount -o remount, rw /system
4. change the permission on the directory                                                                                      chmod 777 /system                                                                                                                 chmod 777 /system/app

Open the perspective in the eclipse, select File Explorer and then /system/app among folders. After selecting push the files in the folder using "Push files on the folder" button.
