I followed this site http://solarex.github.io/wiki/Android/android_ota_update.html
Could you please help to overcome this error

I got solution for incremental OTA zip creation.
Step 1: Copy new OTA and old OTA zip files from out/target/product/xxx/obj/PACKAGING/target_files_intermediates/
Step 2: ./build/tools/releasetools/ota_from_target_files -i old.zip new.zip update.zip
Incremental OTA file will be generate.

infer -- gradle build is not working

I'm trying to use the Infer tool to analyze my app code. I followed these steps and every time I'm trying to run infer -- gradle build I'm getting the below errors :

Any idea would be appreciated !!

I found that Infer is already included in the new android studio 2.2 where you can run it directly from Analyze->Infer Nullity then specify the scope.

compilation error with the build.py script in Kivy

I have recently installed a Ubuntu 13.10 virtual machine and have set the Kivy development environment for it i.e cloning kivy, building a distribution with distribute.sh and building an apk with the build.py script. While packaging my project to APK file and while running the ./build.py script i had the following error :
[aidl] /home/administrator/sdk/build-tools/19.0.1/aidl: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
BUILD FAILED

it is really confusing! I have downloaded SDK and NDK and pointed to where these files are located while setting my environmental variables. what am I missing?

Well i have solved it in the end! And the clue was here
[aidl] /home/administrator/sdk/build-tools/19.0.1/aidl: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
Explained : the Linux distro that i am working on is on a 64 bit machine so some c++ libraries were necessary to be able to run 32 bit applications so what i did is the following:
$ sudo apt-get install lib32stdc++6
and it was solved!

Android Nexus 10 AOSP build AndroidViewClient

I finally managed to successfully build a Nexus 10 image (full_manta-userdebug) with Google Mobile Services installed but unfortunately, I'm unable to use my MonkeyRunner script that uses AndroidViewClient. It crashes out of the script with the following:

Do I need to install the ViewServer for this to work or did I forget to include the uiautomator backend when I built the image?

Try uiautomator from command line to find out if it's there or not:
$ adb shell uiautomator
if your output is similar to
Usage: uiautomator <subcommand> [options]
Available subcommands:
help: displays help message
...
then you have uiautomator installed. Otherwise if the output is
/system/bin/sh: uiautomator: not found
then you forgot to include it in the image.
You don't need ViewServer if UiAutomator is used as AndroidViewClient back-end.
