Following my previous question on how to make the weather widget work again on my Samsung Galaxy Alpha, I have researched about app reverse engineering including Java and Smali as suggested by the answer there. By following this tutorial , I was able to get to the Smali code, make a slight modification to it which I hope will resolve the javax.net.ssl.SSLException: hostname in certificate didn't match error I was getting, and then get to my modified and deodexed .apk. Essentially, the command I executed were:

7za x WeatherDaemon2014_LMR.odex.xz
oat2dex.bat WeatherDaemon2014_LMR.odex temp.dex
java -jar baksmali-2.0.3.jar -a 21 -x temp.dex -o deodex

At this point, I edited the \deodex\com\sec\android\daemonapp\ap\http\HttpClientThread.smali file. Then I executed the below, which gave me the deodexed .apk:

java -jar smali-2.0.3.jar -a 21 deodex -o classes.dex
7za u -tzip WeatherDaemon2014_LMR.apk classes.dex

I am however unfortunately getting a Class not found when unmarshalling: com.android.packageinstaller.InstallFlowAnalytics error when trying to install the modified APK. I have also tried uninstalling this system widget first with Titanium Backup, but the issue remains the same. (This actually corrupted the widget which couldn't be restored, and I had to re-flash the stock ROM to get back to the starting point.) Therefore rather than trying to install the APK, my goal is now to directly replace the WeatherDaemon2014_LMR.odex.xz file located in /system/app/WeatherDaemon2014_LMR/arm/, hence my question of how I could re-odex my APK. I have tried to follow this tutorial but am getting a only position independent executables (PIE) are supported error in step 6. Then I tried the solution here , but am getting the same error in step 5. Researching this error leads to suggestions to compile with the -fPIE option enabled, but I am unsure how and where to do this. Can anyone familiar with app reverse engineering suggest a way forward? Is there a simple way I can get to a .odex.xz file from my modified APK? Apologies if I'm missing something obvious, or if anything I said above isn't making sense, as I am still new to reverse engineering.

Whenever I'm connecting my Samsung Galaxy A40 running Android 9.0 to a laptop or PC, I'm getting an annoying prompt to allow data transfer, and the following setting which I had set to "Charging phone only" gets reset to "Transferring files": However, I only want to charge the phone and absolutely never allow data transfer for security reasons as I frequently have to connect my phone to public or workplace PCs for charging. The service which throws the notification/prompt is called *Android System* and the icon looks a bit like this (only with filled font): I activated developer options and explicitly configured the USB connection settings to **not** allow data transfer. Why does *Android System* keep changing my settings and prompting for data transfer? Is this normal behaviour? Is there a way to regain control without having to root the device?

The integrated weather widget (AccuweatherPhone2014_S_LMR_HD.apk) stopped showing up-to-date weather data on my Samsung Galaxy Alpha (SM-G850F) when I had to update it from Android 4.4.4 to 5.0.2 a while ago. I have tried deleting cache and data, but all it did is erase the cities I have saved there, and which I am not able to get back. Now it reads "Tap here to add a city" and when I do this it keeps saying "location error" or "network connexion error": I get the following error message in the LogCat: ADVHTTP IOException javaxnetsslSSLException: hostname in certificate didn't match: != OR OR OR OR OR javax.net.ssl.SSLException: hostname in certificate didn't match: != OR OR OR OR OR Note that this is the same error as when I still had the city data and tried to refresh the weather. My first step would be to at least get the cities and clock back in the widget, and then if possible resume the weather feed. My questions would be: 1. Does anyone know what is causing this error above? (Why would it expect "a248eakamainet" or a variant of it as the host name?) 2. How can I can potentially resolve it myself (e.g. by using a proxy or installing a certificate)? 3. Failing this, is there a way I can set the city myself by amending the files in there manually, such that at least the clock works (summer time icon etc.) and the city name shows? Not sure if it helps but the file structure in the widget folder is as below:

/data/data/com.sec.android.widgetapp.ap.hero.accuweather/cache/com.android.opengl.shaders_cache
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/databases/WeatherClock
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/databases/WeatherClock-journal
/data/data/com.sec.android.widgetapp.ap.hero.accuweather/databases/worldcity.db

/data/data/com.sec.android.widgetapp.ap.hero.accuweather/shared_prefs/pref_widget_count.xml

(I was able to explore the worldcity.db database using DB Browser and can see all cities data are there.) I am not a developer but have some knowledge in programming, my phone is rooted and I am somewhat familiar with running commands via ADB (I recently managed to solve a keyboard language issue myself by extracting files from a stock ROM ). My phone can access the Internet without any issues, both via WiFi and mobile data. Things I have tried so far to no avail: - Delete cache and data of the weather app. - Update the weather app (version stayed at 150901.800410 despite the "App installed" message). - Manually update the certificates in my phone by following steps described here . - Contact AccuWeather support, their reply was that "The preinstalled application on your phone was developed by a 3rd party manufacturer, with AccuWeather supplying the underlying weather data. The manufacturer is responsible for databasing, displaying, and formatting this data, as well as ensuring it is up-to-date and cached properly.". I did not contact Samsung this time as they were unable to help with the keyboard language issue I had previously. (At this point this is probably obvious, but I thought I would also mention that I am not interested in alternative weather widgets. I am also well aware that this is an old unsupported phone, but there are personal reasons why I want to make it work. I see this as a personal challenge.) Any help would be greatly appreciated!

Many different root-only actions involve mounting and editing files in the Android /system directory. Because there have been so many types of Android OSes, rooting techniques, and actual root solutions from the last decade, it has made it difficult to confidently determine if this is possible with my current root solution: Magisk with locked bootloader. From my understanding, Magisk is a completely "systemless" root solution, so by simply disabling Magisk and rebooting, *all actions performed as root are reverted.* This is important for me because I have verified boot with a locked bootloader via [avbroot](https://github.com/chenxiaolong/avbroot/) , so if there is any change to the system partition then it will fail to boot and the device will be bricked. So, with Magisk, is there a specific module that is required in order to "write" to the system partition systemlessly, so that it's not actually changing anything in the real system directory? Or does Magisk do this by default, and all I have to do is make my file edits from a shell like ADB root or Termux su, and they will be applied systemlessly?

I uninstalled the DocumentsUI only to know it wasn't "just" a file manager. My /system/priv-app/DocumentsUI is empty. Putting any 3rd-party DocumentsUI.apk in it results in a bootloop. I have a custom ROM (AOSP Extended). Flashing the /system again would fix the problem, I think. Just want to make sure if this will make the condition worse, or am I going alright?

I'm looking for some clarification regarding the AppCloud application that comes pre-installed on Samsung smartphones. From what I understand, it suggests and installs recommended apps, including ones I manually select through its interface. My concern is this: **When an app is installed through AppCloud, is it possible that the app receives the permissions it requests automatically, without any user interaction?** Normally, when I install an app via the Play Store and open it for the first time, Android prompts me to grant specific permissions (like access to the camera, location, etc.). However, since AppCloud appears to be a system-level app, I’m wondering if it has elevated privileges that allow it to bypass this standard permission behavior and grant permissions to apps silently. I’d appreciate any insights into whether this is technically possible—especially considering I’m using Android 14.

I have a Blackview BV8800 running stock Doke OS 3.0 (their version of Android 11). The "MTK Non-Framework LBS" app is non-removable so I assume it's part of the ROM from the manufacturer. I can't find any information about it. Is it dangerous? Should I disable it?

I've got an unrooted Coolpad Porto S running on Android 5.1. I tried to ungoogle it but accidentally removed a vital package. The apps I have been trying to reinstall were com.android.vending and com.google.android.webview (I don't have concrete evidence, but after uninstalling it, I am unable to access any browser application like DuckDuckGo or even Steam) by using pm uninstall -k --user 0 APP. I've been trying to install those back using APKs I got from APK Mirror, but if I do through my phone or through adb, they appear in the app list as "Downloaded", however they're also "Not installed for this user". I tried installing them through using adb install -r app.apk command, then going into adb shell mode and using pm install -r --user 0 app.apk, but still the same result. If I don't use the -r option, it just gives me INSTALL_FAILED_ALREADY_EXISTS error. If it helps, upon doing pm enable --user 0 com.android.vending, it gives me Error: java.lang.SecurityException: Permission Denial: attempt to change component state from pid=4418, uid=2000, package uid=10015error. After tinkering about for a bit, I am still having a ton of issues with doing that. If it helps, I found the base apk location for the WebView app. It didn't work trying to pm install -r --user 0 directory, because INSTALL_FAILED_DEXOPT, but I managed to get the crash in logcat.

Not sure if it helps, but here it is. Anyone got any ideas?

In Android, you can go to the App info page and do things like see how much data storage it's using, force stop the app, and uninstall it. If the app isn't installed via the Play Store or APK (i.e., it's installed in the /system partition), the Uninstall button is replaced by the Disable button. Why does the Disable button require the app to be rolled back to the factory version before it will disable it?

Just as the title says, is there any **non-systemless** Xposed framework available for flashing through recovery instead of a Magisk module? I'm on Android 9 and have complete R/W access to the /system partition. I want it because: 1. I need it to persist after factory reset 2. I have posted my debloated/degoogled stock ROM on XDA, and it needs to be installed by flashing the system.img. I want to have Xposed preinstalled in the ROM. Thanks for answering.

I want to research the bloatware that I disabled using pm uninstall -k –user 0 and I just realized that I don't know how to make a list of those specific apps. I can list the file names stored in /system/app but it would be very tedious to find which ones are disabled and also to figure out their package names. pm list has a -d option to display disabled apps, but it only works for apps disabled from within the android menu. If it helps, the phone in mind is not rooted and it is running Android 6.0.1.

I have PDF files in my Android, especially in Dropbox. When I open a file, it's opened by the the Dropbox PDF Viewer. Once opened, there is an option, the button"Open with". If I open the the button, a little window opens with a choice of PDF apps, as Adobe Acrobat, CamScanner, Xiaomi PDF Viewer, etc. When I choose and app, I can click on 'just once' or 'remember this choice'. I'm not sure that I reproduced the accurate words. I'm accustomed to click 'just once'. But accidentally I clicked on Adobe Acrobat, remember this choice. So the PDFs went opened everytime with it. I want to reverse the process and get back the multiple choice. I tried to find a way through the app settings, but nowhere I'd find Adobe Acrobat as default settled. Can someone guide me how to get my old setting? Note. My phone is a Xiaomi Poco F3. Note: I tried this: 1. Apps 1. Manage Apps 1. (A vertical line of three points in the right upper corner of the screen) 1. Other settings 2. Default Apps 3. Opening links 4. To deactivate Adobe Acrobat reader. But it's inefficient. Can someone give me a solution?

I want to change my default file picker, but when I go to settings, the option to change the default file picker doesn’t appear. I’d like to know if there are any apps or modules (I have root access) that could help me make this change. I also have Termux, so if anyone has code that could help, I'd appreciate it. Currently, my default file picker is com.android.documentsui, and I want to change it to com.marc.files.

I have a device running on Android 14. There is the "Codec status" app, which is a system app. I want to disable its notifications, but the "Show notifications" toggle is greyed out. I've searched around a bit, but the only answers I could find were for older versions of Android that don't really work anymore or require root access, which I would like to avoid, given that I like having a warranty. How do you disable notifications for system apps on Android 14?

I'm using Android 14 with KernelSU root access and TWRP recovery on a OnePlus 12 running OxygenOS 14. **What I've Tried:** - I can see /product/app/YouTube/YouTube.apk using Termux or Root Explorer when the system is booted, but I can’t delete it because it's read-only and mounting doesn't seem to work. - TWRP doesn’t show the /product/app/YouTube folder, so I can't access it through recovery. - Tried uninstalling YouTube using Lucky Patcher, but it reappears after reboot. **Question:** How can I permanently delete the YouTube app and prevent it from returning after each reboot? I'm not looking to just disable it; I want to completely remove it from the system.

On a Cheap Chinese Android phone ( a honda civic sold to me with the price & specs of a Maserati ) , running plain vanilla android - my apps crash arbitrarily and I seem to think the culprit is a chinese app that shares the same uid:gid aka system with other apps that have this uid:gid. So If I pm disable it will disable my launcher toggle button as well as I cant launch settings . drwx------ 8 system system 3488 2024-08-29 00:32 /data/data/com.auroradroid.softmanager I am rooted. What If I chown it to another non system UID:GID and then disable it. Any idea what happens then in terms of sequelae ?

I am using the default clock application on a Realme 8 5G phone to set alarms. Today I remembered an important alarm I wanted to set. However, my companion was in bed and I did not want to wake my companion up. Hence, I did not want to have the ringtones play when I selected them. But I couldn't just leave the default ringtone because my companion doesn't like it. Thus I must select a different one so that it doesn't bother my companion when it goes off. My idea was to turn off the volume and select the ringtone by ringtone name (in silence). I might have them memorized by name or just want to wait till it goes off to hear it. My strategy was to turn the volume off. However, clicking on the ringtone still makes me hear it. Why doesn't Android silence the ringtones when I do this and select them, one at a time, in turn, from the ringtone radio controls? Is there a way to select the ringtones without making a noise? Thanks.

I moved a large volume of photo files from my Samsung Galaxy S10 (running Android 11) to my computer for backup, but then copied them back, realizing that I still wanted them on the phone. Now some of them are listed in the Pictures app as taken on the day I re-added them. How can I get them sorted under the proper dates?

I have my phone rooted with magisk and am running a ROM based on Android Pie, which doesn't come with GApps, and therefore has builtin apps to do stuff, my interest is in the gallery app. I configured OpenGApps to not install Google Photos, and preserve the existing gallery app instead. I would like to take a backup of it so I can use it anywhere in the future, however the obvious way fails: ES File Explorer doesn't even see it, Lucky Patcher doesn't allow .apk backups of system apps, and I went into the directories manually only to find the lib folder outside the .apk. Am I safe to just copy the .apk and ignore the lib folder, or is there any other way I can try? Thank you for your time. Note: I would like the app saved as a single "normal" .apk file, instead of having the lib folder outside and having to carry that around, plus I wouldn't be able to place it if I didn't have root (for example, a new phone).

Was just messing around with the list of apps in my phone and found an app named "AgingFunction". No, it is not one of those apps that have that aging filter that make you look old or something. It's a system app that does not have a wrapping GUI. Felt off so looked it up online but didn't find much. Recently heard about Samsung putting an app that throttles performance on devices for so-called device life-prolonging, but turns the throttling off during synthetic benchmarks and stress tests to make it look like device performance stays constant while it does not. Is this a similar case and should I remove it (can't really remove but disable it using platform tools)?
