Issue
i use NetBeans to develop an HTML5 cordova-based android app. Netbeans and android SDK is installed on an linux Workstation - Ubuntu 14.04 (x64).
For that, I like to run the app insight an existing (and running) android emulator (AVD). The AVD works fine and is also reachable using telnet:
$ telnet localhost 5554
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Android Console: type 'help' for a list of commands
OK
But: if I try to execute/run the app in NetBeans, NB returns 2 dialog boxes:
info: Connecting to android device...
and
error: Please run Android Emulator
I had the same setup on windows running out of the box. But it is not working on ubuntu.
So my question is: how to debug this problem and what could be the reason, why NetBenas does not find the emulator?
Is there an NetBeans setting somewhere?
//Edit: with the Help of @ladar i found out, that an library is missing:
libstdc++.so.6: cannot open shared object file
This library is needed by adb
, which is startet by NetBeans.
But: After installing libx32stdc++6
and libx64stdc++6
the error still exists.
adb
is unable to locate that library:
$ ldd /opt/android-sdk-linux/platform-tools/adb
linux-gate.so.1 => (0xf778d000)
librt.so.1 => /lib/i386-linux-gnu/librt.so.1 (0xf7632000)
libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf762d000)
libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf7610000)
libstdc++.so.6 => not found
libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf75ca000)
libgcc_s.so.1 => /lib/i386-linux-gnu/libgcc_s.so.1 (0xf75ad000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf73fd000)
/lib/ld-linux.so.2 (0xf778e000)
The 32bit files was placed in. /usr/libx32/
. So I added an link to /lib/i386-linux-gnu/
.
Running strace
recognizances the library at its new possition, but still resuolts in an error:
$ strace /opt/android-sdk-linux/platform-tools/adb

...and I have no idea why....
Solution
I like to answer my own question for the case, that someone has the same issue: installing the 32bit versions of several packages did not solve the problem.
The point is to install the ...-dev
packages too. The following line solves the problem:
sudo apt-get install lib32stdc++6 lib32z1 lib32z1-dev
