hi can you tell me how to execute the test cases defined in /external/opencore/engines/player/test/src in the donut code?
I have seen the PVplayer documentation , but that does not provide any information.
I am trying to run an SDP file in the PVplayer.
Try to follow the following steps to run the PV Player engine tests (I have done all this with donut code and product Sapphire):
1.You have to include the following line in /external/opencore/Android.mk while making build:
#include $(PV_TOP)/engines/player/test/Android.mk
Either uncomment this (if its commented) or remove any check which is avoiding this line to be included.
2.Build and install the images into phone.
3.Now open shell (use adb shell command). go to directory /system/bin.
There will be an excutable pvplayer_engine_test. Now run the following command:
pvplayer_engine_test -test x y -source xyz.mp4 -logfile -logall
where x is the start test case number and y is the end test
case number.
(For more command line options, please refer pvplayer_engine_unit_test_guide.pdf which is available at /external/opencore/doc location).
Hope this helps.

I want to check SSL verification in my application. I downloaded on my santoku malloDroid.py and try use it (of course earlier I have read that script is an extansion of Androguard). I simply run mallo app: ./malloroid.py -f test.apk and i got import error that there is no androguard module. How to run malloDroid script to verify ssl?
In order to use MalloDroid, you need to have AndroGuard. Setting up Androguard is quite straight forward. Read more about installation here .
Once you have Androguard set up along with the proper environment variables, you can use Mallodroid as follows :
./mallodroid.py -f test.apk -x
This will most likely work!
Python for Android (Py4A 2.6) is wonderful!!! But QPython (2.7) is a lot more powerful and continuously developed. Now I try to integrate Qpython's Python into Android (5.1 CM12) Terminal / ADB described in this Tutorial:http://wiki.qpython.org/en/diveinto/
My Script to import the environment variables qpython needs looks like:
TERM=screen
PATH=/data/data/com.hipipal.qpyplus/files/bin:/system/bin:/system/xbin
LD_LIBRARY_PATH=.:/data/data/com.hipipal.qpyplus/files/lib/:/data/data/com.hipipal.qpyplus/files/:/data/data/com.hipipal.qpyplus/lib/

Shell session:
u0_a101#C1905:/ $ source /sdcard/qpyenvnew.sh
u0_a101#C1905:/ $ $python
u0_a101#C1905:/ $ hmm do nothing?!
I get no output.
I have found here on Stackoverflow the same Question but the posted solution ist a link how is down.
Other Tutorial on throws only errors
http://dinostest.com/node/28
Try this command in your terminal:
$sh data/data/com.hipipal.qpyplus/files/bin/qpython.sh
Terminal will prompt a Python console.
If your script for the environment variables was obtained by running the code from the tutorial link, it should be correct.
If what you have pasted is exactly what you entered, the problem would be that you tried to run pyhton by typing $python when it should have just been python
Pre-fixing with $ is used to reference the value of a variable, so entering $python referenced the value of the variable python but does nothing with it, hence no feedback.
EDIT2: Although it's not a direct answer to this question I suggest having a look at the App 'Termux'. You can install Python2/3 via apt, virtualenv/-wrapper etc... Much more powerfull!
EDIT: Since /data/data... is only accessible as root, the following must be done as root!
Take care that the python executables path is in your $PATH. That wasn't the case even after having run the script from the tutorial (your script). If it's not present simply type:export PATH=/data/data/com.hipipal.qpyplus/files/bin:$PATH
or follow theses steps. In short: create a file in /sdcard (here ".bashrc") with the above line. After that type: source .bashrcsource init.sh (init.sh is located in /data/data/com.hipipal.qpyplus/files/bin as well) Then fire up Python with python-android5 which is the PIE compatible executable for Phone with Lollipop and above. But be aware: For whatever reason I couldn't exit() or quit() the Python prompt but I was able to run Script from the Terminal! Have fun!
EDIT: I spotted this: PythonForAndroid. It is a fork of PythonForAndroid that is still alive, and this versions are able to run on Android L (Python3 on 5.1.1 in my case). Also check the SL4A linked there, it works great on Lollipop.
Thanks to the answers above I made a super easy solution. If you have root: Create a file "python" and type the following line in it:
sh data/data/com.hipipal.qpyplus/files/bin/qpython-android5.sh
Place this file in your /system/bin directory and you can access python from everywhere using the command 'python'.
I have just built Libgit2 (v0.20.0) for Android (target SDK version 18, debugging on a rooted device running Cyanogenmod 10.1.2, Android 4.2.2) and a simple function like getting the version number of Libgit2 works fine through the JNI. But when I use the git_clone function it stops right after the objects/info folder is created and returns this error:
Error -1 cloning repository - Failed to set permissions on '/storage/sdcard0/it/ptt/.git/objects/info': Operation not permitted
I have given the application the WRITE_EXTERNAL_STORAGE permission but I guess it still can't chmod unless owner of the file. When I use adb shell to check out the permission mode of the info folder I get:
d---rwxr-x system sdcard_rw 2014-05-15 09:31 info
And by using pwd.h functions I get the username that the c code (that is calling git_clone) is under to be u0_a92. How am I suppose to get pass this I suppose very Android related issue? Is there a simple way to stop Libgit2 from calling p_chmod or can I give it permissions to do so?
I ended up defining p_chmod as a method always returning true to get passed the error. In the bash script I use to build libgit2 I inserted the following lines that leaves the source files in an unmodified condition after building for android:
LIBGIT2_POSIX_PATH="$LIBGIT2_SOURCE_PATH/src/posix.h"
LIBGIT2_POSIX_BACKUP_PATH="$LIBGIT2_SOURCE_PATH/src/posix_original.h"
printf "#include \"always_success.h\"\nint always_success() { return 0; }" > "$LIBGIT2_SOURCE_PATH/src/always_success.c"
printf "int always_success();" > "$LIBGIT2_SOURCE_PATH/src/always_success.h"
cp $LIBGIT2_POSIX_PATH "$LIBGIT2_POSIX_BACKUP_PATH"
sed -i "s/^#define\sp_chmod(p, m).*$/#include \"always_success.h\"\n#define p_chmod(p, m) always_success()\nextern int always_success();\n/" $LIBGIT2_POSIX_PATH
# run the build process with cmake ...
# restore chmod manipulated source header
mv $LIBGIT2_POSIX_BACKUP_PATH $LIBGIT2_POSIX_PATH
There is probably a cleaner way to solve this but at least now I dont get that error anymore. Thanks to Carlos for his help!
UPDATE
Running adb shell mount | grep sdcard I could see that the sdcard which I am trying to clone the repository into uses the vfat file system which according to this forum thread doesn't support unix-style permissions.
I would like to use the apitrace project on android. I followed the instructions from the readme file.
But get no trace where created.
I run this command
adb shell TRACE_FILE=/data/test.trace LD_PRELOAD=/data/egltrace.so am start -n APP_NAME
How can I make it work?
I tried following the instructions in Dalvik.markdown of the original distribution of apitrace, but without success.
The instructions say to set two properties: wrap._process_name_ and debug.apitrace.procname. The former has to be set, according to those instructions, to LD_PRELOAD=/data/egltrace.so. When launching the application I still wouldn't get any trace generated nor any apitrace-related message in the logcat.
I had more success by putting the LD_PRELOAD instruction in a script and using that as the wrapper. This is the script that I use, called /data/apitrace.sh:
LD_PRELOAD=/data/egltrace.so exec $#
You can also set the TRACE_FILE environment variable to specify the path to which the trace file should be written to. Otherwise it will be _/data/app_process.trace_. For example:
TRACE_FILE=/data/apitraces/mytrace.trace LD_PRELOAD=/data/egltrace.so exec $#
I believe apitrace takes care of adding numbers to the filename to prevent overwriting existing ones. So you'll have mytrace.trace, mytrace.1.trace, and so on.
So with this script in place I set the properties like so:
adb shell setprop wrap._process_name_ /data/apitrace.sh
adb shell setprop debug.apitrace.procname _process_name_
And then I launch the application. I see in the logcat something like the following:
I/dalvikvm( 5980): Exec: /system/bin/sh -c /data/apitrace.sh /system/bin/app_process /system/bin --application '--nice-name=_process_name_' com.android.internal.os.WrapperInit 25 17 'android.app.ActivityThread'
D/apitrace( 5991): apitrace: loaded
D/apitrace( 5991): apitrace[5991]: enabled for _process_name_
D/apitrace( 5991): apitrace: tracing to /data/app_process.trace
I'm using CyanogenMod 10.1.3, which is based on Android 4.2.2.
I'm facing a bug in a makefile build system (Android built under Linux) - some files are removed by an 'rm' command, and I can see that command in the build log.
How can I find the exact line in the makefiles which calls the 'rm' ? Is there any automated method?
For GNU Make you can do the following trick:
__shell := $(SHELL)
SHELL = \
$(warning making '$#'$(if $^, from '$^')$(if $?, because of '$?'))$(__shell)
SHELL variable is expanded each time when Make invokes a sub-shell to execute a recipe. In these lines it is replaced so that on each expansion it will print a target, its prerequisites and prerequisites that are newer than the target. Also each debug message is prepended with the file and line number of the rule being executed.
The same technique is used in GMD to set breakpoints to certain targets.
Assuming your make is a Gnu make, you can also pass some debugging options, like --debug=b (basic debugging messages, very often enough) or --debug=all which is the same as -d
Some files may be removed because they are intermediate. Read also about secondary files and precious files in make
You may try make -d -w and then grep your file from huge amount of output lines.
