How to install an APK as system app - General Questions and Answers

Hi,
I recently used "System App Remover" and deleted a system app "amigo_dynamicweather.apk". That app did not create a backup before deleting it. Anyways, I got that apk somehow but when I try to install it manually, I get "App not installed". So I tried to install it by moving it to system/app folder and set permissions to RW-R-R using root explorer, rebooted and nothing. App was in the system/app directly but I cannot see it installed. The permissions still are RW-R-R. How can I install it? Please help.

[Q] pushing app to system

so it seems its a system limitation when using dialer apps where the missed call notification doesn't get cleared when opening the dialer app.. the stock phone app needs to be opened in order to clear it...
i'm running cm7.1 on nexus s 4g.. just installed touchpal dialer.. i read on this site
http://stackoverflow.com/questions/2007024/push-my-apk-to-system-app
that you could push the app into the system folder and that would address the problem.. i downloaded the app from the market so no idea how to get the apk..
i assume if i could get a hold of the apk.. i could use root explorer to change the persmissions, then move the file into system/app and then install the app??
any help would be appreciated.
p.s. all i really want is the search feature of these apps which stock dialer doesn't have.. which is a big oversight by google not to have this.. so if any other solutions are available.. great.. love to hear them
The apk should be somewhere in /data/app, there are also apps that let you backup apk files to sdcard.
Afterwards remount /system to read+write and push the apk file to /system/app.
do i need to uninstall the app from /data/app after? or should i leave that file in there
Using Root Explorer, find the apk in /data/app, long-press and select move. Navigate to /system/app, mount r/w (by pressing the button at the top), and paste. Long-press the apk again, select permissions and set to rw-r--r--, then mount r/o and reboot.
Voila! Your user app is now a system app. You can also use Titanium Backup to convert a user app to system app and vice versa. As I have the paid version I'm not sure if this feature is available in the free version.

thanks.. seems to work now.. i'm surprised apps can't automatically install in that way to notifications can be dealt with.. guess they don't have permissions to install into system?..appreciate the help.. all works now!!
so seems doesn't like to work like that.. every time i reboot i get a force close popup... then i have to delete the app and restart.. had permissions set correctly and everything

Spice Stellar MI 500

Hi, I have a spice stellar mi 500. i tried rooting the phone which worked fine and then I tried removing some of the system apps like Rail yatra,, facebook, dhingana. i was able to remove them and then i finally booted my device. Since then I am getting the error "unfortunately system UI has stopped working" I am not able to open apps or receive calls. the system hangs. not even able to unroot the phone now as any apps will hang. even the control bar does not slide from the top. I am screwed. I have tried factory reset several times. in all different ways like from with system recovery or android settings. but i guess i am out of luck. can someone help me. :crying::crying::crying::crying::crying::crying::crying::crying:

You have most probably messed the systemUI.apk which is located in /system/app or files associated with it. Did you remove any other apk's in which you weren't sure what it does?
In this case, Factory reset won't work because it just wipes user data and /system partition remains in tact. The nearest possible thing to do is to flash a stock ROM if exists or copy the deleted apk's borrowing from some one else's phone and place those apk's in /system/app partition setting the correct permission.
I remember exactly what I deleted. I I uninstalled Dhingana.com, Facebook and Rail yatra. I cannot start third party apps though I can install them. So I am not sure how to place the systemUI.apk in the directory /system/app. Can it be done through inbuilt file manager?

Nope, I guess not possible through default file manager. You have to use ES File Explorer File Manager or Root Explorer to place it in /system/app and change its permissions to rw-r-r.

I tried replacing systemUI.apk to \system\app folder using esexplorer but i got error. error: copy failed.
is there a possibility I can get hold of a stock rom and flash it using update from SD card. the default android update manager?

Make sure you've mounted the /system partition as R/W before attempting to Copy or setting permissions.

Using root explorer I moved an app into the system/app folder, changed permissions, and it still isn't showing in the app tray. Any ideas would be helpful.

[Q] Uninstalled TaskManager by mistake

Could someone help me? I uninstalled the Task Manager by mistake. I already extracted it from the zip file of the rom, but i am not sure about how to reinstall it. I am using NExtGen Rom
If you already have the apk, simply use a root explorer and copy the apk to system/app folder. Change permissions to rw-r--r--. Reboot, and done!

[Q] Put app in system

Can anybody tell me how to install apk from phone as system app

Then reboot. If the app doesn't appear in your app drawer, go back to /system/app and install the apk like usual from that folder. Reboot again and see if it works.
