These are the steps if you are installing a system apk for Android 5.0 or later devices. For older versions use posaidong's answer

Rename your apk file to base.apk

$ adb push base.apk /sdcard/  

Enter the console and get the shell

$ adb shell

Switch to superuser. If your device is not rooted, get it rooted first. (If you don't know how to do that, just Google.)

$ su 

Remount the system partition with WRITE permission.

$ mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system 

Create a Test directory inside /system/app folder. (or can use /system/priv-app as well). Ideally this folder name should be application name. For now, lets use Test

$ mkdir /system/app/Test 

Requires 755 permission for this dir

$ chmod 755 /system/app/Test 

Copy your base.apk inside

$ cat /sdcard/base.apk > /system/app/Test/Base.apk 

Remout /system partition back to READ-ONLY, and exit

$chmod 644 /system/app/Test/Base.apk 

Requires 644 permission for this dir

$ mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system

$ exit

Reboot your device. When boot completes you should see a system message like Android updating ...
