How to solve android studio first run issue?

I installed android studio on my reinstalled 20.10 groovy gorilla. When I run it, I find this error:
And then I get this error if i click cancel:
Please help me solve this error.

Try to open the program from the terminal by entering the directory where the program is stored and typing open -a programNameHere. If that doesn't work, delete and reinstall the sdk.

It is more of a Linux permission related. You might have extracted android studio into /opt as they have mentioned in documentation. I can suggest few solutions.
Extract android studio in home directory of user. Make sure not to use sudo or root to extract tar. Since you are extracting in user home directory, you don't have to use root.
OR
Install (extract) Android Studio in /opt with proper permissions.
Create a new directory in /opt/android, using sudo mkdir /opt/android.
Change ownership of /opt/android directory to the current user, using sudo chown -R <USERNAME> /opt/android. Replace <USERNAME> with the current username.
Extract android studio tar file in /opt/android directory. Don't use sudo or root extract files.
PS: Above mentioned solution no. 2 is dirty solution. /opt directory is used for multi user application. To allow multiple user, we have to create system account and add current user to newly created account's group. If you are not looking for multiuser solution then go with solution 1

Android SDK on Alpine - adb No such file or directory

I'm trying to build an Alpine image containing the Android SDK - specifically, the platform-tools package.
My Dockerfile does the following:
Installs Java and sets JAVA_HOME (needed for Android).
Downloads the Android SDK tools from Google.
Unzips the package.
Sets ANDROID_HOME. Also sets PATH so the sdkmanager executable can be used.
Installs platform-tools using sdkmanager.
Adds platform-tools to PATH.
platform-tools contains an executable named adb, but for some reason it cannot be seen. Running adb returns:
bash: /android-sdk/platform-tools/adb: No such file or directory
Here is my Dockerfile:
FROM alpine:latest
# Install bash and java
RUN apk update
RUN apk add bash openjdk8
ENV JAVA_HOME=/usr/lib/jvm/java-1.8-openjdk
ENV PATH="$PATH:$JAVA_HOME/bin"
# Download Android SDK and set PATH
RUN mkdir /android-sdk
RUN wget https://dl.google.com/android/repository/sdk-tools-linux-4333796.zip && unzip *.zip -d /android-sdk && rm *.zip
ENV ANDROID_HOME="/android-sdk"
ENV PATH="$PATH:$ANDROID_HOME/tools/bin"
# Install platform-tools
RUN yes | sdkmanager "platform-tools"
ENV PATH="$PATH:$ANDROID_HOME/platform-tools"
RUN adb version # throws error: adb not found
I've looked at this question but the problem should be fixed with platform-tools v24.0 and higher.

Alpine uses musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements.
adb is compiled with glibc, so it won't be able to run in Alpine, which usually results in the error: No such file or directory.
You can verify that a file is compiled with glibc by running file <path to file> | grep "interpreter /lib64/ld-linux-x86-64.so.2".

This may help, although the Gradle daemon randomly crashes for me on Alpine Linux when using the compatibility layer.
gcompat is the go-to compatibility layer for Alpine users.
apk add gcompat
After that you run your binaries as normal.
Source: https://wiki.alpinelinux.org/wiki/Running_glibc_programs

You can install android-tools like so:
RUN apk add \
android-tools \
--repository=http://dl-cdn.alpinelinux.org/alpine/edge/testing
The key is to set the --repository as shown, as it's only in the edge testing repo.
I don't think it includes the whole SDK, so may need to download and unzip as well for other tools. I don't know if this will handle everything you want, but adb prints a help document at least.

Aidl not found,but it already exists

if i type in buildozer -v android release.and not in root.
Check that aidl can be executed
build-tools folder not found /home/m/.buildozer/android/platform/android-sdk-20/build-tools
Search for Aidl
Aidl not found, please install it.
but if i type in aidl
enter image description here

I have been having this error for a long time and multiple instances, even after trying to reinstall Aidl, reinstall buildozer, and deleting .buildozer project file.
Problem
This was caused by installation of wrong/outdated/mixed android-sdk build tools at;
~/.buildozer/android/platform/android-sdk/build-tools
Note:
Buildozer can only build without Aidl error if only the latest/correct android-sdk build-tools are installed.
Solution
Navigate to android-sdk build-tools path as shown below;
cd ~/.buildozer/android/platform/android-sdk/build-tools
Check the latest build tool you have, type;
ls
You should see a list of folders with names 29.0.0, 29.0.2, or any other folders.... this can be different. Note the latest version, eg (from example above is 29.0.2)
If this folder is empty proceed.
Type;
sudo rm -Rf *
Then run the following command;
cd ~
On the command below, replace "build-tools;29.0.0" version flag with your latest version (Noted above from ls command). eg ("build-tools;29.0.0" to "build-tools;29.0.2"). Use the command as it is if the build-tools folder was empty.
Hit enter to download.
~/.buildozer/android/platform/android-sdk/tools/bin/sdkmanager "build-tools;29.0.0"
Navigate to your Buildozer build project folder, run;
buildozer android debug
I hope this will help you solve the problem.

Android Studio 2.3.3 stucks when first run

I downloaded Android Studio 2.3.3 for Linux and unzipped the content to /usr/local
then
$ cd android-studio/bin
Edited the file idea.properties and appended a following line to it:
disable.android.first.run=true
Then launched Android Studio:
$ sudo sh studio.sh
Looking in classpath from com.intellij.util.lang.UrlClassLoader#1a7cec2 for /com/sun/jna/linux-x86/libjnidispatch.so
Found library resource at jar:file:/usr/local/android-studio/lib/jna.jar!/com/sun/jna/linux-x86/libjnidispatch.so

^C[18124266] WARN - pl.local.NativeFileWatcherImpl - Watcher terminated with exit code 130
And it will stuck. After long waiting I termited it with Ctrl+C

Try attaching to the process with strace to see what it's doing (for example, waiting on a network or file). Or run it with strace like this:
strace -o foo.log -s1024 -f ./studio.sh
After a while, break it with Ctrl-C and examine the log file for syscalls like open, read, recvmsg.
Alternatively, while it's running, you can attach with a Java profiler to the jvm. For a start, you can launch jconsole or jvisualvm and attach to the Android Studio (it will show as an empty name, with only PID) and view stack traces of individual threads. In jvisualvm you can view the CPU usage sample and click on the hot event and see the stack trace.
Basically you need to find out what the app is trying to access for so long. Most likely some network resource.

I think all your problems happen because you ran as root (sudo) on your first run.
So try to unroot before doing a clean install like I suggest below:
Unroot the installation
cd to the folder where you unzipped Android Studio before
cd ..
Recursively change user and group:
sudo find <thedirname> -print0 | xargs -0 chown <yourusername>:<yourgroupname>
cd ~ or cd to go back to home
Recursively change user and group
sudo find .Android* -print0 | xargs -0 chown <yourusername>:<yourgroupname>
(I sudo because you've used root user previously).
Recursively change user and group
sudo find Android* -print0 | xargs -0 chown <yourusername>:<yourgroupname>
cd into the unzipped directory. Do chmod +x studio.sh.
Start Android Studio ./studio.sh
If it didn't help, do a:
Clean install
Download and unzip a fresh copy of Android Studio. I suggest version 3, it's pre released, but stable. It doesn't matter where you put it.
I believe you have Java installed, but make sure you have Java 8 as the default one: in command line: java -version, make sure it's 1.8.
Move any old installations out of the way, in case they are corrupt:
sudo mv ~/.Android* ~/tmp/
sudo mv ~/Android ~/tmp/
should do the trick. (I sudo because you've used root user previously).
cd into the unzipped directory. Do chmod +x studio.sh.
Start Android Studio ./studio.sh
Make sure all the files are owned by your username, and group as well.

I took some information from:
Stuck at “.android/repositories.cfg could not be loaded.”
Installing Android Studio in Ubuntu 14.04 64-Bit .android/repositories.cfg could not be loaded
The answers collectively say that:
Android Studio will run fine without repositories.cfg.
You can remove this warning by putting the following into repositories.cfg:
### User Sources for Android SDK Manager
count=0
After waiting some time it eventually goes beyond that step.
Patience is the key.
So, try waiting a little bit more. It always helps.

This is common. On your first run the gradle files are needed to be downloaded and installed in background. It's about 90 MB in size and even if your internet speed is high, the gradle servers may be slow taking it to maximum of 1 or 2 hours in the worst case. So open Android Studio and wait until it opens. Hope it helps.

I've found a potientaly useful link from AskUbuntu, the guy suggested creating an empty file called repositories.cfg. And that solved it.
Ref: https://askubuntu.com/questions/885658/android-sdk-repositories-cfg-could-not-be-loaded

Just remove /root/.AndroidStudio2.3 and /root/.android (after making a backup)

Maybe it has something to do with the script looking at the root location. Have you tried using chown on the unzipped content directory?

Try this to install
Download the studio
Extract to home
go to android-studio/bin/
Mouse right click than open terminal
type ./studio than press enter
now it will start to install studio. If you installing first time than It will download some files of SDK. and if you have already downloaded SDK than you can cancel download and set you SDK path from the setting from right bottom corner.

try creating repositories.cfg -- Because I see it as warning. Let's see what happens after that!
touch ~/.android/repositories.cfg /* Linux */

Extract your downloaded Android Studio setup zip file to your /home/<user_name> directory and in terminal follow the below commands
$ sudo chmod +x studio.sh
And hit enter
Now run the following command
$ ./studio.sh
And wait for some time to download the required libraries.

Building liblinphone for Android

I am building Linphone application for android. I am using windows xp 32 bit.
1) Download android ndk
2) Installed the autotools: autoconf, automake, aclocal, libtoolize pkgconfig
3) run the ./prepare_sources.sh/
I got the output in terminal as
$ ./prepare_sources.sh /cygdrive/d/android/androidNdk/android-ndk-r8d
using /cygdrive/d/android/androidNdk/android-ndk-r8d as android NDK
./prepare_sources.sh: line 23: git: command not found

Any info, questions or anything really is highly appreciated

Part 1
The following steps can help you create and install the build on your device or emulator(Tested on Mac):
Step1: you need to have the Android SDK and NDK configured and istalled
Also install Autotools Mac users can use this link (Follow point 2.3 only in the link)
Other platform users please make sure you install it correctly.
Step2: Mac users open up your terminal and clone the git repo on any directory you want
to by running the following command: (Other users sorry i don't know how but i think you can figure it out that how you can get the git repo on your directory using command promt or whatever you are using)
$ git clone git://git.linphone.org/linphone-android.git --recursive
After you get the Repo copied into your directory now go to the directory and open the README file and read out the whole file.
Step3: Now we will follow as the instructions written in README file
First Go to root directory of the downloaded project using the following command on Terminal:
Mac users on terminal write cd and
then drag and drop the "linphone-android" folder on terminal
(when you drag and drop the folder terminal will get the path of the folder and then you can hit enter to get into the directory of that folder)
$ cd /Users/myname/Desktop/Android/linphone-android
or just use simple command cd to get into the folder
$ cd Desktop
$ cd Android
$ cd linphone-android
Now when you get into the directory on terminal then check your PATH of SDK & NDK installed on your Mac run
$ echo $PATH
if you see the path with SDK and NDK location then it's ok to proceed with Step4 and skip the below part and if not then you need to setup the PATH before you execute the make and make install script in Step 4:
To set up path use :
$ export PATH=/Users/myname/Documents/adt-bundle-mac-x86_64-20130729/sdk/platform-tools:/Users/myname/Documents/adt-bundle-mac-x86_64-20130729/sdk/tools:/Users/myname/Documents/android-ndk-r9:$PATH
it's like export PATH=(Path of your SDK platform tools folder):(Path of your SDK tools folder):(Path of your NDK folder):$PATH
This will set up the path and to confirm again run
$ echo $PATH
Now you will see that the path of SDK and NDK is there.
Step 4: Now if the Path is already setup you can simply run
$ make
Now connect your Device to you Mac/Pc and see if eclipse has detected it.
After the device is connected run:
$ make install
$ make generate-sdk (optional)
This will install the application into your phone. (you need to have an working SIP username and password to configure in the app)
This above steps worked for me and i was able to get the app running on my device.
Part 2
Importing into Eclipse :
After you have made your build then now you need to import it into eclipse.
Step1: Go to eclipse click on File Menu then Import then select
Existing Android Code into Workspace
Hit Next and Browse to the linphone-android project folder
And Only tick linphone-android folder and Leave Copy project into workspace untick.
Do this Like the below image:
And hit finish.
Now you right click on "linphone-android" (project name) and go to Properties and Java Build Path and then Order and Export and then reorder them as my image below and untick gcm.jar
Hit OK
And Boom No errors
Now just run it on device or emulator. (Make sure your minimum target SDK matches with your device or emulator.)
The above steps worked fine for me and it will work for you as well.
All the Best !!

According to README in root dir of linphone-android you don't need to run prepare_sources.sh, remaining steps for you is to run "make" and "make install":
LINPHONE for ANDROID
**************
To build liblinphone for Android, you must:
0) download the Android sdk with platform-tools and tools updated to latest revision (at least API 16 is needed), then add both 'tools' and 'platform-tools' folders in your path.
1) download the Android ndk (>=r8b) from google and add it to your path.
2) install the autotools: autoconf, automake, aclocal, libtoolize, pkgconfig
2bis) on some 64 bits systems you'll need the ia32-libs package
3) run the Makefile script in the top level directory. This will download iLBC source files and convert some assembly files in VP8 project.
$ make
4) To install the generated apk into a plugged device, run
$ make install

Existing answers shows how to build old linphone but to Build Latest Linphone for Android You can follow these Steps:
1) First Download Android SDK (at least API 16 is needed)
2) Then Download Android NDK(>=r9d) from Google.
3) Then Install cmake, python, yasm nasm Dependencies which is further required while installing Linphone. you can install these tool through Terminal.
4) Then You have to download source code of Linphone using following command:
git clone git://git.linphone.org/linphone-android.git --recursive
5) After Downloading Source code You have to set Path of Android SDK,NDK and also JDK
in Android SDK You have to give path upto Tools.
For Example : in console type following command
export SDK_PATH=/home/rajesh/android/adt_bundle/sdk
export NDK_PATH=/home/rajesh/android/android-ndk-r10c
export JDK_PATH=/usr/lib/jvm/java-7-openjdk-i386/
export PATH=$PATH:$NDK_PATH:$SDK_PATH/platform-tools:$SDK_PATH/tools:$JDK_PATH
6) After setting path you have to navigate through Linphone directory and type command “./prepare.py” then This will configure the build and generate a Makefile in the top level directory.
If you get following error: CMake Error Could not find the intltoolize program then
Refer
http://lists.nongnu.org/archive/html/linphone-users/2015-07/msg00092.html
7) After setting path you have to navigate through Linphone directory and type command “make” then it will generate apk for Linphone.
8) To generate a liblinphone SDK zip containing a full jar and native libraries, run
$ make liblinphone-android-sdk
I hope this helps.
