Answer 1

I can install an APK to /system/app with following steps.

1. Push APK to SD card.

   $ adb push SecureSetting.apk /sdcard/  
   

2. Enter the console and get the shell

   $ adb shell
   

3. 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 
   

4. Remount the system partition with WRITE permission.

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

5. Cat your APK from /sdcard/ to /system/ , some guys get a fail with cp command due to cp is not supported. So use cat instead.

   $ cat /sdcard/SecureSetting.apk > /system/app/SecureSetting.apk 
   

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

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

Then reboot your device, the APK should have been installed on /system/app.

Answer 2

settings -> sdCard & phone storage says about /data folder.

/system is mounted separately and I guess there is no way of writing there unless you make your own Android build.

See mounts by running

adb shell

# df

Answer 3

If your apk is smaller enough to push in, then try some times again. I met the same problem and tried twice to push the apks to /system/app/

Answer 4

If you're simply looking to install it, you can always do: adb install myApk.apk.

Answer 5

You have to mount system as read/write and then push the application.

Answer 6

Apparently, there is not enough space for your application in "/system" mount. You can check that with "adb shell df" command.

To solve this issue, you need to set partition-size parameter adequately while starting your AVD like this:

emulator.exe -avd <your avd name> -partition-size 512
