[Android-development] Debugging on device, any success?

[Harri Pasanen]

Hi,

I wonder if everybody else is happily debugging on Android and it is 
just me who is having issues?

I'm not able to debug anything on my Nexus 7 tablet, gdb times out. Qt 
5.3.2, Kubuntu 14.04 amd64 host

Almost immediately after startup I get the message box:

Connecting to remote server failed:
Remote communication error.  Target disconnected.:
Connection reset by peer.


Not sure if I should post here or at qt-creator list.

Anyway, some log snippets below, full logs on request.

It appears to initialize after some ping/pong:

I/Qt JAVA ( 3628): DEBUGGER: waiting for pong at 
/data/local/tmp/qt/debug-pong-com.mpaja.mbraille2, attempt 5

I/Qt JAVA ( 3628): DEBUGGER: go to sleep

I/Qt JAVA ( 3628): DEBUGGER: waiting for pong at 
/data/local/tmp/qt/debug-pong-com.mpaja.mbraille2, attempt 6

I/Qt JAVA ( 3628): DEBUGGER: go to sleep

Could not load shared library symbols for 96 libraries, e.g. 
/system/bin/linker.

Use the "info sharedlibrary" command to see the complete listing.

Do you need "set solib-search-path" or "set sysroot"?Unable to find 
dynamic linker breakpoint function.

GDB will retry eventurally. Meanwhile, it is likely

that GDB is unable to debug shared library initializers

or resolve pending breakpoints after dlopen().I/Qt JAVA ( 3628): 
DEBUGGER: waiting for pong at 
/data/local/tmp/qt/debug-pong-com.mpaja.mbraille2, attempt 7

I/Qt JAVA ( 3628): DEBUGGER: got pong 
/data/local/tmp/qt/debug-pong-com.mpaja.mbraille2


But then dies shortly after.


Looking at the debugger log in qt creator, it says:
