In the Android.mk file you also need to specify all the source file you want to use within the LOCAL_SRC_FILE directive.
First of all you need to mofify the Ccollege Admission Essay Related 17 Txt 17 AndroidManifest.xml file adding the attribute “debuggable” to true ( remember also to enable the “Debug USB” option under the Application device menu ).
At this point you can debug all the java code within your eclipse debugger, for for the native C debug you need more steps.

This file is used by the the “ http://www.fanoff.com/shows/?phd-thesis-microfinance Phd Thesis Microfinance run-as” command to know the process privileges and its folder content.
If on your device this service is unavailable you need to create one.

The file format is very simple. every line has 4 columns: package name, user id, debug flasg (“0” or “1”), applicatio folder.
You can do this: from Eclipse install the application just using the “Run as” command ( or via shell writing: adb install package.apk ). Now in a new terminal window write:
Just copy the output ( which is the user_id, for instance 10042 ) and exit from shell ( using “exit” command).
Now we have to get the app folder. Unfortunately the /data/data folder is protected, so you need to log into the device and obtain root access.
host:~ $ adb shell su
# cd /data/data
# ls -l -h
Look for the folder associated to our user ( in our example is: com.darkwavegames.esempio ).
Now we have all the informations for creating an entry for the packages.list:
host:~ $ adb shell su
# cd /data/system
# echo com.darkwavegames.esempio 10042 1 /data/data/com.darkwavegames.esempio > packages.list
Now the run-as command will find all the required informations. Custon Writing Com
Note that in case you uninstall and reinstall the application you need to to repeat this steps because the system could have assigned a new user_id to that application.
Now you should be able to run the ndk-gdb script ( executing it inside the project folder ) and set breakpoints on the native code.
At this point starting ndk-gdb from the project folder should be enough. If you’ve verified all the above prerequisites and your code is simgle thread this should be enough.
Instead, if your native code is multi thread, the gdbserver which comes with the r4b can’t debug your code ( probably it has been compiled without the multi thread support ).
In this case you need to obtain from the android repository Buy Karelia Software Sandvox 2 oem git://android.git.kernel.org/platform/prebuilt.git the “prebuilt” folder of the SDK. Now that you have download it into your Uwc Essay Help $PREBUILT folder you need to download the gdbserver with multi thread support from this link.
Copy the gdbserver just downoaded into folder $ANDROID NDK PATH/build/prebuilt/$HOST ARCH/arm-eabi-4.4.0/bin where $HOST_ARCH is your developement architecture ( darwin-x86 if you’re with mac osx ).
Copy $PREBUILT/$HOST ARCH/toolchain/arm-eabi-4.4.0/bin/arm-eabi-gdb into $ANDROID NDK PATH/build/prebuilt/$HOST ARCH/arm-eabi-4.4.0/bin and use it as debugger.
We’re close to the goal!
Now modify the “install-binary.mk” script inside $ANDROID_NDK_PATH and change the line
$(call cmd-strip, $(PRIVATE_DST))
$(call cmd-strip, $(PRIVATE_DST))
In this way, if in out Android.mk file there’s a directive APP_OPTIM with the value “debug”, the symbol strip will not be executed.
Now in order to have the debug running we need to add a breakpoint in the Where To Buy Dissertation Uk Java code just before the http://idproscapes.com/case-study-papers/ Case Study Papers System.loadLibrary() method and start a new debug session from Eclipse.
As the code reach the breakpoint, open the terminal, enter the project folder and write these commands:
host:~ $ adb shell ps | grep com.darkwavegames.esempio app_42 4512 2377 648 332 c0318ffc afd0eafc S com.d...
host:~ $ adb shell
# cd /data/data/com.darkwavegames.esempio/lib
# ./gdbserver :5039 --attach 4512
Without close terminal, open a new termina window and execute:
host:~ $ cd workspace/esempio
host:esempio $ adb forward tcp:5039 tcp:5039
host:esempio $ adb pull /system/bin/app_process \
host:esempio $ adb pull /system/lib/libc.so \
host:esempio $ export NDK_BIN=$ANDROID_NDK_ROOT/build/prebuilt
host:esempio $ $NDK_BIN/darwin-x86/arm-eabi-4.4.0/bin/arm-eabi-gdb \ -x obj/local/armeabi/gdb.setup -e obj/local/armeabi/app_process
gdb.setup is generated by the ndk-gdb, but is created into the libs/armeabi folder. It’s important to copy it into the “obj” folder and add the line “target remote :5039”.
Now from the gdb prompt it’s possible to add breakpoints and execute all the debug instructions such as step into, over, continue…
All these steps are included in the “remotegdb.sh” file, so you don’t need to write all these commands every time! Just execute this script in the project folder ( the same folder where the AndroidManifest.xml is located ).
