[Q] System App - Android Q&A, Help & Troubleshooting

Hello to all,
I would like to know, Android Jelly beans you can install an app as system app?? If it is possible in that folder must be inserted so that it can be installed as a system app?
thank you very much :highfive:

You can't install as system app without root. If you are root, I can help you, but if not, I can't

I'm sorry,
I took for granted that my smartphone was root.
So now you can proceed to tell me how to install an app like app system.
You know me also say that there are advantages to install an app like app system rather than as a normal app?

Some apps have to be installed as system apps, usually ones pulled from other devices or unofficial updates to a system apps which refuse to install from an apk. Besides for apks that won't install normally, I don't really see the reason to install an apk as a system app, unless you want to make it harder to uninstall.
Installing an apk as a system app is done with a rooted device only, by placing the apk in /system/app and changing the permissions to match other system apps. I like to use ES File Explorer.

Depending on the rom (but generally all alow debugging through adb) you should be able to install an apk to system parttion pushing it with adb to the /system/app/ directory

You can also use Titanium Backup or Link2SD to convert any user app to system app, and vice versa. Most of us have at least one of those apps installed, anyway.

thank to all for helping me,
remove them manually, use root explorer or similar, and go to system/app and delete de apk directly from there.

Sounds like Chrome does not want to be installed as a system app then Is there some benefit to having an app installed as a system app? Or why do you want to have it installed as a system app?

OK I don't know how things work on phones outside of the HD2, but can't you just push the .apk to /system/app with a root explorer, fix permissions in CWM and reboot?
Try to use ADB to move it and remember to set permissions
You need to extract libchromeview.so from the Chrome APK (found at: com.android.chrome-1.apk/lib/armeabi-v7a/libchromeview.so) and move it to system/lib. Optionally, you can remove libchromeview.so from the Chrome APK and zipalign if you want to save a couple of MBs of space.
This worked for me on v. 0.18.4531.3636. I attempted this some time ago on an older version unsuccessfully. If you have an older version for some reason, you'll probably need to update.
Latest titanium backup update said something about fixing conversion in what's new

If I'm not mistaken system apps load first on boot and are often quicker at starting up than user apps. That's been my experience anyways. However a lot of em are more hassle to convert than the slight increase in speed is worth imho

Well im asking myself about your answer and how its conected to my question....
How its a quastion for legit or not? If someone give his employs a phone and want to disable the camera?
Like in samsung fectory allowed to enter with cameras and phones with cameras? Right? Is it not legit?
Think before you answer....
Well, if the user who wants to uninstall an application from your phone doesn't know about root,titanium backup (there is an option to uninstall system apps there) etc then your best bet is to move it to /system/apps. If the app is there then it cannot be uninstalled through normal methods.
Bdw, you should've put your question in the Q and A section
Cheers!

to install an apk in /system/app , u should copy the apk using "root explorer" for example to that directory and set permissions to rw- r--r--(read write then read read ) but remember u have only limited space on ur /system directory about 500 mbs only
however u can use a launcher like apex , it has a feature to lock the desktop of launcher to prevent moving widgets or uninstalling apps from app drawer
u can also use an app like app locker and lock the installer app and settings app on ur phone with a secret code preventing anyone who doesnt know the code from accessing settings or unisnstall apps

well thank you very much i will look into it.
if with that app i can lock only this specific install then all good , if i disabled all other install uninstall its not good for me.
also for using root explorer i need to root the phone move the app install then unroot the phone
can i put that installer inside the rom and flash it ? will it auto install the app when flashing this rom ?

If that application is a system app, then you have to root your phone ... But i don't think you'll be able to root your phone yet ..

Thank you. Yes, I think that application is a system app. I think also root is possible ( i'll try motochopper for mtk6589 devices) but I don't know how to locate the chinese app and what's the app name. Do you have an idea for me?
Ok, my phone is rooted. Ther's some apk that allows download of others chinese app. But I don't know what it is.
Any idea?

With some file explorer ( I recommend ES file explorer - you can get it off Google Play or as a apk file if you don't have Play Store installed, it's a free app) go to /system/app and there you will find all the stock apps. Delete the ones you don't need, but be careful not to delete something your phone needs such as SystemUI or something like that. Also you might have to mount /system first. Do that by clicking root explorer in ES and then when it shows up a pop up window make sure that the dot is set on rw for the /system . Otherwise you won't be able to delete anything.

Very thanks. I'll try this.
I saw that some apps have the suffix [3738] (for example GoogleService [3738].Apk). I do not think they're stock apps. I will try to remove these first.
Thanks again

Sure!

Attension ! What is root ! Wht actual mean ! Can i make a app to root mobile !

Hello All .. Thank :good: for being with me here :laugh:
I know what is ROOT actually i Don't :crying:
I Successfully Rooted 100 < Smartphones , also Recovery flash with CWM
But still i am confuse what is actually mean by ROOT ????
I quit sure that its like a administrator privileges , is it ? OR its 777
i am 100% sure Recovery in android like a bios setup ..
So finally question please tell me easily and short what is ROOT .. cause i Want to make a app that can ROOT any ANDROID without any other tool (s/w ,, h/w) escape an Target device with OS.
You don't know what root ist but want to develope an app that can root any device!?
So root is a user which has all privileges.
I don't think that the app is possible because you need root to root your device or you modify your system from external (like from recovery)
