Android studio downloads x86 images from google and emulate them so I can test my apps. I tried downloading and unzipping the thing it downloads but it doesn't look like an image that can be run with virt-manager. Which images are downloaded by Android Studio and how can I emulate them in Ubuntu?

How does one root a Samsung Galaxy S II GT-i9100 (with its original Android 2.3 Gingerbread), preferably under Linux Mint? This questions pertains specifically the GT-i9100 version (not GT-i9100G nor GT-i9100T, et cetera), which currently has no entry under the rooting index . I am particularly looking for a rooting method which does not wipe the data on the phone, as [I am hoping to recover data afterwards](https://android.stackexchange.com/questions/89133/data-recovery-on-boot-looped-samsung-galaxy-s-ii-gt-i9100) . I have an 8GB external SD card.

I want to send some specific files from my linux PC to my android device. I'd like to send it automatically using terminal commands, so there will be no drag and drop files. I don't know what is the best communication way to send file via wifi. I understand how to send using ftp by downloading 'ftp server' app on my android, but that's not suitable to my work since it needs to open an internet browser on my PC and transfer like a file manager. So I tried using ssh: scp /home/user/picture1.jpg u0_a167@192.168.1.117:/storage/emulated/0 but always ended up error: ssh: connect to host 192.168.1.117 port 22: Connection refused lost connection How to solve this problem? or does anyone have any other recommendation which communication way should I use?

In my office my mobile used to be connected to the office Wi-Fi. There I didn't face any internet problem, all apps work fine. But in my home my mobile is connected to my Laptop's shared Wi-Fi and Laptop is running on Kubuntu 15.10. In this case some apps like Play Store, youtube, telegram, WhatsApp and all browsers, etc. work well, but some apps do not work, sometimes partially work or otherwise show the message >No internet connection. What's wrong with connection from my laptop to my mobile, and why are some apps working and some are not? How can I solve this?

I have a Chromebook with an ARM processor. I have installed Ubuntu on that Chromebook. However, since there is no Skype-binary for ARM Linux, is it possible to use the version of Skype of the android APK, and run that on my ARM Linux ? Is there some kind of Dalvik enviroment or converter for ARM Ubuntu ?
What would be the minimal emulation environment, if I wanted to emulate android ?

## The issue I needed to push a folder to my phone and I just ran the following command which always worked fine:

adb push ~/some_folder sdcard/some_folder

For some reason however it just didn't respond and stayed quiet in the terminal. After a while my system started lagging, then I looked at the RAM usage and was shocked when saw that 30GB of RAM was allocated. After looking back at the terminal, it also showed >Exception occured ... std::bad_alloc. It also didn't respond to my Ctrl+C, so I crashed the terminal which freed the memory. To make the final test I ran the following two commands to exclude the possibility of folder being to large

mkdir test
adb push ~/test sdcard/

Yet the result were the same. ## Pc Info 1. OS: Arch Linux 6.16.3-arch1-1 2. ADB: comes from package android-tools-35.0.2-17 from arch linux repository. ## Phone Info 1. Make: Xiaomi 2. Model: POCO X6 Pro 5G 3. Android version: 15 AP3A.240905.015.A2 ## Some additional info 1. Never experienced something like this before, Always was fine with pushing/pulling any file, including folders. 2. My adb also sometimes just freezes without responding (but without any else negative effect i listed above) on pushing regular files, but reconnecting the USB helps (for folders it doesn't) Anyone else experienced the same issue? Would be glad for any help!

I see, Linux kernel sources for Redmi A2+(water) are unavailable. Have anybody this sources? Maybe somebody write kernel drivers for this smartphone?

Is there any way I could block Android Apps for example Instagram from accessing the Internet, using the SQUID software or something similar on my Personal Computer?

I am using Kali NetHunter on a rooted Android device, and I'm encountering an issue with Bluetooth. Whenever I try to enable Bluetooth through the GUI or using the command line, it simply doesn't turn on. I can see the Bluetooth icon, but it stays stuck on "Turning on." It was working in the beginning, I could connect to headphone, I sent a video file from PC to tablet via Bluetooth.

service bluetooth status

>bluetooth is not running ... failed! Then I started

service bluetooth restart

>Stopping bluetooth: /usr/sbin/bluetoothd.\ >Starting bluetooth: bluetoothd. but this does not restart the Bluetooth. Right after start command, service Bluetooth status still says "Bluetooth is not running ... failed!" I already ran these commands:

sudo apt-get update
sudo apt-get install bluetooth bluez
sudo systemctl start bluetooth
sudo systemctl enable bluetooth

lsusb command shows this: >Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub\ >Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub It does not show anything about the Bluetooth adapter I also added kali-tools-bluetooth, but this did not help either.

> adb shell sh-4.1$ su Permission denied I have rooted my phone successfully. I know this because I'm able to install apps on SD card and I have a program called SD Maid that is able to operate with root permissions.

I am running out of Ideas how to get MTP working _again_... I am simply not getting the dialog again on my android, asking me wether I want just charging, or MTP or Picture mode... **Until most recently, it was easy: Use a USB cable, concect it to my Ubuntu 16.04 Laptop, get the mentioned choice/approval box...** and voilà the Tablet appeared as an MTP device in the Ubuntu ‚file explorer‘ (caja) nicely auto-mounted. * got an Samsung Galaxy S2 tablet * running Android 6.01 * it worked until recently in this configuration I already followed some advice: * I made the developer options visible (by tapping the about device info thrice) * enabled USB debugging (which some sources say, is something to watch out for) * dialed on the phone menu *#0808# → which shows I'am on (o)AP and on MTP + ADB mode just like I should (this radio box btw only holds its state, if USB debugging is enabled) also... * tried different USB ports * tried different cables * tried with another device (MacBook. Thus I have no reason to believe, I messed something up on the host machine OS side... Ubuntu is very stable anyway) * External Store (4kb) under Settings→Applications→“Show System Apps” is on well, one last clue: * Settings → Tethering has the USB switch grayed out „USB cable not connected“. Althoug it clearly is. And I can recharge my tablet through it (otherwise I would have certainly noted...) Device is not rooted. No other glitches. Are there maybe some log files (now that Dev mode is enabled) to check out what might got wrong? Not looked/understood ADB yet. So I couldn't tell you, if that works. Anyway, no dialog to choose upon connecting. I am out of ammo :-( **Thank you for any piece of advice...**

Can I ssh into a Linux Server from my Android device?

I have a problem with audio streaming that I can not listen audio from Pulseaudio when using VNC with a Linux Desktop Environment. However it works if I export the audio to XSDL. But the problem is that after I exit the application the sound does not work in the background. I know that Pulseaudio only supports Xorg servers, so how to stream audio to VNC or any other application on Android and to run it in the background. I know that there is an application Simple Protocol Player that listens to pulseaudio sound from Xorg Server, but it does not work for me and I do not know the reason.

There is a vendor image in my device I want to change (unpack/mount, doing changes, pack/umount). My purpose is to update boot.img with my new kernel (in a rooted device). Unfortunately, it does not work due to incompatible versions between a newly compiled kernel (my compilation) to the previous kernel modules stored in vendor.img. As I figure it, I need to update the old ko executables stored in vendor.img in my product. The first step is to do dd from my device and adb pull it out to my build environment. While I tried to do a mount on vendor.img, I discovered it not working due share_blocks attribute blocking it to mount as RW (dmesg wrote: "...unsupported optional features (4000)"), To solve it, running the following command e2fsck -y -E unshare_blocks vendor.img will disable the share_blocks feature that prevented me to do mount as RW. Of course, doing mount RW works correctly. In the last phase, I tried to replace files in the vendor filesystem and then I discovered another challenge into my way, Unfortunately, there was a problem with limited space in the file system, For example: In case I want to replace the kernel module called abc.ko, deleting the file doesn't show any new free space in the file system. At this point, I can't update the old kernel modules with the new ones (compatible with the newly compiled kernel). Of course, running df -h . returned no free space and 100% used. Does anyone have any idea what I need to do?

I'm discovering the possibilities offered by persistent live USB using Ubuntu 19.10 and I was wondering if it would be possible to boot with Ubuntu on Android (i.e. using your computer capabilities through your smartphone) using those multi-plug USB sticks which have both USB3 and micro-USB2. In other way: can I get some kind of a boot menu on an Android device in order to boot with a persistent live USB in order to access my Linux computer tools and setup from a wider range of devices?

I am not sure where to start all help is welcome. I have a Samsung Phone and computer for flashing.

Since a nice Wacom tablet is a bit pricey, especially for someone like me who doesn't do much graphic editing, I was wondering if it is possible to use a tablet (i.e. my Nexus 7) as a Wacom-esque drawing tablet when connected to a Linux computer? I did a bit of searching, however most of the info I found is for using a Wacom tablet on an Android device. I've never used a Wacom device, however I have been doing some graphic editing in Gimp, and think it would be much easier than just using a mouse. And since I have a Nexus 7, it seemed like the logical place to start. I would have to use the Nexus as a USB peripheral for the computer, and I don't know if it is possible to transmit the touch screen coordinates to the PC. If anyone can point me in the right direction, I'd appreciate it!

Having just installed waydroid , how is the Google Play Store installed?

$ sudo waydroid shell
/system/bin/sh: No controlling tty: open /dev/tty: No such file or directory
/system/bin/sh: warning: won't have full job control
:/ # whoami
root
:/ # exit

$ waydroid status
Session:	RUNNING
Container:	RUNNING
Vendor type:	MAINLINE
Session user:	nicholas(1000)
Wayland display:	wayland-0

$ waydroid --version
1.3.1

The directions are: waydroid app install xyz.apk Which is easy enough. However, there's no mention per se of installing the Google Play Store and secondary sources would indicate that alternates must be used. Looking to install some sort of repository to pull in mainstream apps like gmail. What repo's can be installed?

I'm trying to run a sh script (easyrsa) while being in sudo -u root environment. sudo -u root sh /data/data/com.termux/files/home/openvpn/easy-rsa/easyrsa3/easyrsa This gives me an error telling me that OpenSSL is not present (I assume because I'm running it in a different environment) And when I try sudo -u root /data/data/com.termux/files/home/openvpn/easy-rsa/easyrsa3/easyrsa It gives me "No such file or directory". I tried every possible combination of commands but just can't seem to get it right. The main issue is I'm trying to run easyrsa from a web dashboard for generating certificates, and this dashboard is running as sudo -u root and for some strange reason, it just can't find the files in termux home. /data/data/com.termux/files/home/openvpn/easy-rsa/easyrsa3/easyrsa is my location of the easyrsa shell file
