So i'm gonna be as elaborative as much as I could..
I have a Xperia L with latest firmware and I was trying to set some third party apps to system apps, and I succeeded after some time I thought that if I could set App updates to system app (meaning removing the older version) and I succeeded again but when I was doing the same to Chrome I stumbled upon to a problem..
So before I tell you what was the problem i'll tell you how I did it..
1.I updated Chrome.
2.I moved the original. apk from "system/app" dir to My SD so that it can be changed to new one. (My set is ROOTED)
3.Then I moved the. apk from "Data/app" folder to "system/app" folder.
4.And renamed it to the Original. apk 's name.
5. And changed the Read/Write Permissions as it should be.
6.That's that.
So after that I tried launching chrome but it said
"Chrome failed to start due to an Unexpected Error"
but with above methods I replaced a lot of apps like Walkman, Calendar, PlayStore, Play Services and some i don't remember...
and they all worked fine even after restarting it..
so then I uninstalled Chrome with Titanium Backup since it was a system app..
and then I tried the same with Album app.
I replaced it's. apk and tried it but it started crashing.. so I deleted it. too and placed the original one back..
and restarted my set..
But now it is stuck on Black Screen after Sony logo...
I know I can Flash the ROM to get going but if there's any other way to do so please let me know..
now i know it's kinda two questions in one but I really need to know both..
Thanks in advance...
You can use Link2SD or other root apps to add them automatically to the system image

I tried running my Flutter app on an emulator and it works just fine. Then after trying out the application a few times, I decided to create an .apk file out of the app, but when I tried to install it on my phone, it just outputs white screen and nothing else (usually when I ran it, it outputs the login screen). I also had my friend install the .apk file to his phone, but to no avail he also reported a white screen and nothing else.
Then I tried another method of loading the app by running the application on my phone, instead of building the .apk file and installing it manually on my phone. To my surprise it works perfectly if I were to run the application from the Android Studio IDE directly onto my phone.
Can somebody point out to me what am I missing here? Am I supposed to change something in my build.gradle file before compiling it into an .apk file? Let me know if you have any ideas!
Thanks!
Are you using Firebase or other packages?
If yes, you can probably having error when use a release mode app. And to fix it, we need to know what packages you are using.
If not, please follow this issue https://github.com/flutter/flutter/issues/70558
Whenever I build a new version of my Android app and install it, it doesn't really make a completely new installation (uninstall and reinstall) it kind of patches the previous version I made. When I launch the app it just crashes.
Then I manually completely uninstall my app and then reinstall it from zero. In this case it works like a charm. The problem is that I'm worried about how will this affect the distribution of my app and automatic updates. Is there a solution?
What I'm doing is this: I have my app, let's say v 3.1, I build the v 3.2 then copy the apk into my phone and execute it. It updates... Then, the app crashes on start. Then if I completely uninstall the app and then run the apk file of that very same version v 3.2 it works fine. I don't know why that happens
As far as crash is concerned you need to print the log , to know why it is exactly crashing, it could be due to some variable on your launcher screen which gets NPE may be because it is getting cleared. Since the package name of application is same it will obviously work in similar manner as you mentioned. Crash must not be due to reinstall of application.Till you find out the reason for crash it will not be possible to tell that exactly how it is going to affect your application.But it is never ok to distribute app which is crashing in any manner.
I have just updated my app on Google Play (just in beta mode yet), and I was quite surprised that when I tested the update the app did NOT restart. How is this possible? For correct behaviour it should restart. (It uses Activities only.)
What if I had significantly changed the app functionality? The old version would run until the user manually restarted the app?
I didn't find a guide on updating Android apps. (just user guides, but they are useless for me).
I figured out what the problem was. I am using a Nexus 7 device, with multiple users, and I had the app installed on both. While the internal storage is different for these apps, the path for the App Expansion Files (shared-storage/Android/obb/package-name) is the same. This caused issues in the non- updated version, because it saw the updated Expansion File, and re-downloaded its own version again.
I think this is quite an issue of the OS, because the two user's versions should not interfere with each other at all.
I am a new programmer for Android, but I have been using eclipse for a year and a half now. I am developing an Android Application for my school's health department to allow students to track certain health behaviors overtime.
I have completed the coding of the app and have successfully tested it on a virtual device. The applications runs fine on the AVD.
However, the problem arises when I export the project as an Android application through eclipse. I create the apk file using the debug.keystore and the androiddebugkey. I create the apk file (which is about 115 kilobytes). Next, I connect by phone (an LG Thrill) and open it via My Computer. I drag and drop the apk file into the "downloads" folder in the phone.
I use a Market App called ASTRO to access the apk file in the downloads folder. However, when I try to install it, I get the dreaded "There is a problem parsing the package" error. I have had this problem for weeks now.
I have tried all sorts of solutions. I have developed the app for the same Android level as the phone. I have tried making my own keystore and exporting. I have also tried making smaller apps (ie: HelloWorld) and installing them. I keep getting the same error.
One thing that I noticed was that whenever I go to the apk file in the ASTRO Market app and click on the apk file and then "Open App Manager", I see that none of the apk file's settings (ie: Name, Size, details) are shown. All the Marketplace apps I have in the folder have visible settings by my apps don't.
What might I be doing wrong? Is it something with building the apk file? Or am I uploading it onto my phone incorrectly? Whatever it is, please let me know.
Go to: Settings->Security->Device Administration and make sure you have Unknown Sources enabled.
Have you checked your manifest file? What is the required minimum version of Android that you need, and what is the version on the device you are installing it on? Everytime I have run into this problem, it is because the device has less than the minimum required version of the operating system on it.
Home-->Settings-->Application Settings-->Unknown Sources Click Checkbox on
I know it's kinda old topic but it has just happened to me (Android 4.1.1).
Solution: If you have wifi turned on, make sure you have internet access. I dealt with this problem and multiply requests to install application appeared.
I have some Android market feedback for my app Hire*A*Droid where users complain that they are unable to uninstall the application. Here's two I have so far (about 10 days apart):
janelle: I uninstalled this app, but its still showing that its
installed under my downloads. What can i do ?
valerie: It's frozen I can't open or delete it.
anyone can help n tell me how..thanks
The app has nothing really special or tricky about it and I never experienced anything of the sort so I'm really lost at what this may be, how real it is and how to reproduce and deal with it? Any ideas, suggestions? If you have any questions that you think may help with this problem I'll be happy to provide more details
P.S. Worth nothing to mention - both complaints cost me a single star rating and no additional info was provided
P.P.S. After comment from PHP Jedi I noticed similar comments for other apps while browsing Android Market. I think this is quite common and it looks like Market bug. I will try to open a bug on Android Market support site

I purchased a DROID a week back and was having the same problem. To uninstall an application from the DROID do the following.
Uninstalling an application from Android OS v2.1
Go to settings.
Go to Applications
Go to Manage applications.
Touch the application you wish to uninstall.
Touch uninstall.
Enjoy the fact that the application is gone.
The confusion I'm guessing your commenter's are having is when you hold your finger on an application you can drag it to a trash bin. This makes you think you are deleting the application when really you are removing it from your favorite applications list. Its very misleading.
from what i understand (i don't work on Market myself), the "Downloads" list inside Market can be out of date for up to a day, until it next gets an update from the server. the app isn't actually installed anymore, and Settings > Applications > Manage Applications will show that it is indeed gone.
i reported this as a Market bug internally last year. i've just added a link to this page from that bug, and i'll try to get someone to look at it.
(it may even already be fixed in newer versions. it would be interesting to know the most recent version you've seen it in.)
I could not say why the users complain, but I could say that your application work without problem on my HTC Magic, I don't get error when I tried to uninstall it.
Best Regards
