Every time I restart my Xolo Era 4g, Android 5 Lollipop phone, it auto enables "allow installation of apps from unknown sources" option. I switch it off manually, then in a few seconds, a pop-up for an unknown app to install shows, and on the background, the "unknown sources" button automatically toggles. This keeps on going forever. I haven't rooted my phone and have factory reset it many times. I first installed an antimalware app, and when I run it, it found around 16 malware, of which I deleted 14 but there was no option to delete the last two. Then I installed the notification app. I restarted my phone. After that, the internet automatically started. I immediately switched it off. Then I went to settings and switched off to allow unknown apps installation. Then I opened the menu and slide it a few times and the malware attacked again. Opening the settings disclosed that an unknown app installation is switched on. Many apps are promoted for installation. After pressing cancel around 50 times, I went to the menu again and many new apps were installed. I have repeated this scenario two times once I switched the internet on. But with the internet off, I saw an app installation prompt too. I don't remember with the internet off whether the apps got actually installed or not. Now I opened the notification app and it showed one process having some text similar to _Andriod UI Lollipop 5.0_, it had a Lollipop icon to its left. On clicking on that, it further showed one process. The process was related to the notification app itself and had text "toaster" or maybe "toasted". Now I have factory reset my phone again and have uninstalled all default apps like Flipkart, Snapdeal, Paytm, UC browser, etc. Now if I'll again restart my phone, the virus will start again. Please tell a method to not allow any app to toggle the "unknown sources" options on without rooting the phone.

After enrolling my Android device in the Intune company portal, I removed it from the company portal. Now, if I install any APK from other sources downloaded via Chrome, it keeps saying > Unkown apps can't be installed by this user. I tried to go to Settings -> Install unknown apps -> Files by Google -> Allowed, still the same error. Device admin apps are all off. Still getting the same error. --- This may answer it: https://support.google.com/pixelphone/thread/249737257/unknown-apps-can-t-be-installed-by-this-user

On an Android TV, I made some backups with CX File Explorer. When I tried to install it on a different SmartTV, the format was not recognized and I realized about a "+" symbol after the "apk" string. I renamed the apk+ to apk, but Android didn't recognize the installation package. So, I installed CX File Explorer, and using it, the apk showed the proper app icon, and installation was successful. What is the apk+ extension? Is it a new "apk" package version? Just a "proprietary" format with a misleading extension name? Are there more apps recognizing these packages?

My phone is an unrooted Samsung Galaxy S7 Edge running Oreo 8.0. Yesterday when removing bloatware from my phone, I accidentally uninstalled a system app using the adb command: pm uninstall -k --user 0 I suspect the culprit to be com.sec.factory.camera, as since that unfortunate event, the camera app crashes every time I try to launch it. I tried reinstalling it using either of these two commands pm install com.sec.factory.camera pm install --user 0 com.sec.factory.camera but they returned a "can't open non-file" error message. I tried as well downloading the APK on my phone and installing it from Android, but at the end of the installation process, I got a "not installed application" message. How to reinstall an uninstalled system app through ADB?

I know there are tons of questions about this, but I have tried many possible solutions to no avail. I believe the "Out of space" error is misleading... I have a problem: **I cannot install any .apk file** no matter what I try... I can install apps using **Play Store** though. When I tap on an APK file in any file explorer, Android Package Installer launches. I tap the INSTALL button but I always got the following error: > Out of space {AnyAPKApp} couldn't be installed. Free up some space and > try again. I have *plenty* of space, but even a tiny 248 KB APK won't install with the same argument... This is the only problem I have with the ROM and it is very frustrating... First, the details of my case: - *Device:* Samsung Galaxy Grand Prime+ SM-G532M, alias Galaxy J2 Prime (Xtreme detects my device as *Model Number:* SM-G950F) - *Android:* 6.0.1 - *ROM:* Xtreme Ultimate V6.0 (15.07.2018) - *TWRP:* 3.0.2-0 - *Magisk:* v17.1 - *Magisk Manager:* 6.0.1 (151) - *Storage:* Adoptable - *Internal storage:* 7.02 GB used of 8.00 GB - *SD card:* 9.09 GB used of 14.70 GB - *Root Essentials "View storage used":* 9759/15787 MB (62%) - *DiskUsage analysis:* /system = 2.94 GiB; Free space 1.61 GiB I've already done my homework and tried all of the following to no avail: 1. Move all movable apps to SD 2. Enable Adoptable storage 3. Wipe *Dalvik / ART Cache* and *Cache* partitions with TWRP 4. Full clean with *SD Maid PRO* 5. Force move apps to SD using *SD Maid PRO* 6. Uninstall *Google Play Services* and *Google Play Store* updates 7. Overcome *unauthorized device* issue while using ADB 8. Trying to install APK using ADB (e.g. adb install someApp.apk). I got: Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] 9. Delete /data/log contents as suggested here 10. Attempt to install in Safe Mode 11. Using Termux and the df command, I got the following output and there is free space in each partition: df output" class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> 12. Using pm install test.apk in a terminal emulator (*Termux*) I got [INSTALL_FAILED_INVALID_URI]. Using full path pm install /storage/emulated/0/Download/test.apk I got the same error: Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] The problem still remains. I think this is not really related to the full storage device error, I have plenty and the error seems misleading. It has to be something else... I gave as much info as I thought it was useful. If more is needed, just tell me to share it. I hope you can give me some advice to try to overcome this annoying issue. *P.S. I'll add more attempts to my list as I try them.*

**Problem** I want to install Android in a VM to restore a backup using Titanium Backup. For this to work, I need Android to be rooted. **What I tried** I've tried to install Android-x86 4.3 in a Virtualbox VM. The installation seems to work. I made an 8GB partition disk (sda1), made it bootable, and installed Android in it from an ISO file. This all seems to work. Android starts, I can browse the internet, install apps, etc. Then I want to restart the VM, and guess what?! I go back to the installation screen, like starting up from the ISO live image. For normal stuff, I can make a snapshot, start that up, and do anything. My problem is that I need root permission to restore a Titanium Backup in that VM. And I cannot root this VM because the disk is not writeable. With Alt-F1, I become root and I can use a script to root Android. But my guess is that I'm still on the ISO and that is not writeable. **Update - another try with Android 4.2** As mentioned in the comments, 4.3 would have problems with root access. I tried 4.4, which didn't start at all. Then I tried 4.2, which has the same problem as 4.3 for me. I made a screenshot of what I see when I try to run the rootscript , which is described here . You can see the errors: **rm failed - Read only filesystem** How can I fix this? **My question** How can I install Android permanently on this VM, so it can reboot and then be rooted?

There is a .xapk file in APKPure and here is the corresponding app on Play Store . I can install it using Play Store. But other approaches of installing this app fail (SAI_v4.5 and other installers), and about 20MB (the size of the .xapk file) is lost after installation failure. I got the error > INSTALL_FAILED_ABORTED: User rejected permissions when installing split APKs (.xapk) on my Oppo Reno4 SE 5G running Android 12. # example commands to install split apks pm install-create pm install-write 18911812 base.apk /data/local/tmp/base.apk pm install-write 18911812 split_1.apk /data/local/tmp/split_1.apk pm install-write 18911812 split_1.apk /data/local/tmp/split_1.apk pm install-commit I tried to install it using ADB, and although pm install-commit returns with a Success message, the app is not fully installed. When using ADB, "Verify app over USB" is turned off. I noticed this error when installing split APKs using a custom app installer from storage. But now I found this error also occurs when installing a normal .apk file (I didn't notice this because I am using Android's default package installer). However, .apk could be installed successfully (at least it seems like it). How to solve this?

M problem is when I go to Audible the error I get is: >The app is available for your other devices. I found that my wife has 10 different Kindles and Kindle Fires. I deleted the oldest two thinking I have too many devices. - I found a site to transfer older Audible APK to pc and then transfer it to the new phone. - Or is there a better way. - I cannot seem to find site again. I have a S24 phone. I think made in Korea made Samsung knock off, not sure. Nothing saying Samsung comes up when phone boots up. Picked it up off Temu. It is running Android 13,with Snapdragon 3rd gen. I checked this with an app to read phone information.

I'm thinking of buying an ARM laptop as a second laptop for programming and hacking experiments. Ideally I would set it up to multiboot Windows, Linux, and Android. I've seen several articles and videos on the internet for setting up x86 Android on an x86 laptop, but can't find anything on ARM laptops. I'm guessing it would come down to things like device drivers and maybe UEFI? Is it possible for a normal person to install Android natively on an ARM laptop intended for Windows/Linux? (And preferably dualboot/multiboot?) (I'm aware some highly skilled hacker types can probably do it using AOSP. I'm also aware I could just use a VM or emulator. For this question I'm only exploring the options of installing natively on the hardware.)

I recently bought a (currently discontinued) Polaroid Cube+ off eBay and I want to be able to use all its features. The instruction manual and other places mention there is an app (package name com.polaroid.cube), but it seems to have been removed some years ago. (Latest version I can find is from 2017, v2.3.8.) I want to install the Polaroid Cube app onto my OnePlus 12 with Android 14, but when trying to install (by running the APK or via adb install --bypass-low-target-sdk-block) it says that it is not compatible with my device. It seems that the architectures don't match (armeabi-v7a, armeabi vs arm64; the specific error from adb is INSTALL_FAILED_NO_MATCHING_ABIS). **Is there a way of installing this app onto my OnePlus 12?** Ideally it should *not* involve rooting, as I have some work-related 2FA associated to my phone that need it to be unrooted. In addition, I don't have any older phones to install the app onto; the goal is to install this ancient app onto my modern Android phone.

I am using Android 4.2.2 Jelly Bean on TI OMAP 5 platform. I want to install applications on an external SD card, but even if a lot of space is free (more than 25MB), I am getting an error "Insufficient storage". 1. Is it possible to install applications on an external SD card in Jelly Bean? 2. How can I move an application installed on internal memory to an external SD card?

I'm facing trouble installing a modded APK if the same app is already provided in stock ROM. I'm using Micromax Canvas E481, not rooted yet. It has the JioSaavn app already installed. I uninstalled it to install a mod version of JioSaavn. But I'm getting the error "App not installed". However, the same APK is working on my other devices. The same is happening for playstore.apk. *JioSaavn* is not a system app, it's just provided in ROM by Micromax. From application, it gives the option to uninstall it. I can install APK for any version of *Saavn,* it's just not letting me install the mod version. If I modify it using Lucky Patcher, it won't install it, but it will let me install the original APK for any version bypassing the pop-up from ES Explorer. When I tried installing it from ADB:

C:\Users\Syed\Desktop\adb-tools_treiber\adb-tools>adb install C:\Users\Syed\Desktop\Saavn.apk

I have a Huawei P60 Pro, and I want to install Android Auto. Tried different ways without success. Found Android Auto as an APK but couldn't get it to work. Is it possible to install Android Auto on Huawei P60 Pro?

I have an APK of [Unlimited Call Log 3.1.1](https://apkhome.io/unlimited-call-log-3-1-1/) , but I am unable to install it on Samsung Galaxy S24+ running Android 14. When I tried to install it, an error comes: > App not installed as app isn't compatible with your phone. Can anyone help to solve this issue or upgrade to new Android level?

I have a phone named Tecno Spark 7T running Android 11. When I tried to install the APKs, I noticed I couldn't install because of this error > Package Installer not working Afterwards, I have tried SAI (Split APK Installer). It gives the proper error > Couldn't download in FRP

The Dcoder  app supports the Python programming language. However, for a code that requires 3rd-party modules (e.g. mlxtend ), it will show the following error when running:

Traceback (most recent call last):
  File "fun.py", line 7, in 
    from mlxtend.data import iris_data
ImportError: No module named mlxtend.data

Process finished with exit code 1.

How to install new Python modules in the Dcoder app?

On my Pixel phone, apps will download on Play Store, but once the download completes, it doesn't install. After some time, there's a notification from the Play Store that says > Google Play isn't responding. Try again in a few minutes, and if the problem continues, get help troubleshooting. (Error code: 927) Usually, if I restart the phone, the apps can be installed, but if I wait a few hours, I have to repeat the process. Does anyone know of a way to fix the issue permanently?

I'm trying to install an apk file on my device, and I'm able to press the Install button, but after a few seconds, I keep receiving this error: > App not installed. What is the root cause of this issue and how can I fix it? I know [this StackOverflow question](https://stackoverflow.com/questions/4226132/app-not-installed-error-on-android) is related, but that question deals more with the development aspect than the consumer installation aspect of the error.

I am currently testing an application which has root detection, emulator detection, and sideloading detection. I am using an Android Studio emulator rooted with Magisk (Android 12). I was able to bypass the root and emulator detection, but not the sideloading one. I am using Magisk + Zygisk. Magisk Modules used: - MagiskHide Prop Config - Play Integrity Fix - Shamiko - Universal Safety Net I have tried installing FakeStore, but it ends up with a signature mismatch error even after uninstalling and removing all com.android.vending related files. Is there any other way to bypass this?

TL;DR - How to uninstall the Google Play store? --- A friend of mine deleted my Google Account as a prank (don't know how it is a prank). When I came home, I just logged in and tried to install some apps, but it wasn't downloading and stuck on Download Pending. Here is a list of troubleshooting I did: 1) Force stopped and disabled. Cleared data and cache. Uninstalled updates. Restarted the APK but still didn't work. Yes, I also gave it time to update. 2) I deleted all my other accounts and just kept my Google Account. Did the same as 1), didn't work. 3) OK. I remembered that there are modded Play Stores available online. So I downloaded the Lucky Patcher Google Play Store (modded) ver. 14. something and it didn't work. Also, did 1) again after I installed it. 4) When I uninstall the update for the modded app, it requires authorization, meaning I would have to sign in again. No problem, but there is no option to log out, meaning the arrow drop-down doesn't appear. Also, I signed out from Settings and relogged in from Play Store, but still, when I open it, it asks for authorization again. 5) I tried to install the Gapps again. In the XDA forum, it was stated that you just need to install the package again and it will replace the existing Gapps. I did it. I downloaded the nano package. But it asks for Authorization. Still no drop-down. I am back again with the Lucky Patcher app. It will let me browse APK and use Play Services, but it won't let me install APKs. How to uninstall Play Store and reinstall it?
