After opening an Android project in Studio running under Ubuntu 15.04 Linux, the following error was displayed,
Unable to establish a connection to adb. This usually happens if you have an incompatible version of adb running already. Try reopening Studio after killing any existing adb daemon.
- Running the
ps -ef | grep adbcommand does not show any running adb daemon.
- Android Studio was started from a terminal. The terminal window shows the error,
E/adb: Unexpected exception 'Cannot run program "/home/user1/Android/Sdk/platform-tools/adb": error=2, No such file or directory' while attempting to get adb version from '/home/user1/Android/Sdk/platform-tools/adb'.
ls -ls /home/user1/Android/Sdk/platform-tools/adbcommand lists the file but the execution of the command,
/home/user1/Android/Sdk/platform-tools/adb, gives the error,
bash: /home/user1/Android/Sdk/platform-tools/adb: No such file or directory.
- The command,
file /home/user1/Android/Sdk/platform-tools/adbgives the output,
adb: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped. The problem is that we have a 32-bit program which we are trying run under 64-bit Linux.
The solution is to install packages which facilitate running 32-bit programs under 64-bit Linux using the commands,
$ sudo dpkg --add-architecture i386 $ sudo apt-get update $ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
After this, Android Studio connects with adb and works fine.
