I have been running the command aapt list -a on an APK file but i keep having the error:
appt command not found.
I have check the Android-SDKs built-tools and the aapt file exist in the location.
Please, what do i need to do to fix that?

You need to set path.
Go to system properties -->Environment variables -->New/Edit "PATH"
Add C:\\AppData\Local\Android\android-sdk\platform-tools

Unable to access jarfile SignApk

I'm trying to sign an APK with SignApk, but I keep getting this error:
Error: Unable to access jarfile signapk.jar
I have appended my JDK directory as well as my SignAPK directory to my system path variable. The java command works fine through the command-line, but I can't seem to get the -jar option to work correctly for signing APKs.
My SignApk folder is located on my C:\ drive, so it looks like this:
Here is what I am trying to do through the command-line:
Please ignore the blank space in between the variables as I was trying to cover up my details. The syntax that I am using is:
java -jar signapk.jar certificate.pem key.pk8 myapk.apk myapk-signed.apk
I have tried the commands from the SignApk directory as well as the bin directory inside of that directory. Can anyone help me troubleshoot how to resolve this issue? Thanks

As you might notice, there is no signapk.jar file there, there is only signapk without extension.
Download different SignApk from here:
http://www.mediafire.com/download/h5fob1afzt1p4ss/SignApk.rar
Password: SanketN8

just download Signapk.zip and unzip wherever you wish, paste your apk inside the signapk folder.
open cmd / terminal , change directory to signapk
java -jar signapk.jar testkey.x509.pem testkey.pk8 test.apk test-signed.apk
copy and replace with you existing file name (test.apk) and output file (test-signed.apk )

In case one encounters this message when signing a LineageOS build:
Get rid of ./build/tools/releasetools/ prepended to (old) commands used for signing.

i got this codes from a site. (http://www.apriorit.com/our-company/dev-blog/233-how-to-build-apk-file-from-command-line)
i downloaded the source code sample and opened the batch file in there but it didn't generate it's apk file. usually the apk file is located at its bin\ right? but when i opened the folder, the file is not in there. please help me how to use this one. i'd appreciate you help.

You’ll have to have Apache ant for this one:
ant debug
This will build and sign the necessary .apk files.
For more info, please see this: http://codeseekah.com/2012/02/09/command-line-android-development-basics/
EDIT:
ant is not a part of standard Android SDK setup. You'll have to install it.
Download the latest ant zip file from The Apache Ant Project.
Extract the zip file to a folder, say c:\ant\
Add c:\ant to your path environment variable
Once these are done, you'll be able to run ant from the command line

The apk by default is located under bin and this is correct, but when you distribute source code it's better to not add any apk because a "fresh" compiled apk is always a better solution.
if you have a file called build.xml in the root of your project just do
ant debug
otherwise you need to update your project with the minimum informations required for the building phase with
android update project -t android-10 -p .
in this case android-10 is a target for your apk/app/api and you can customize this option for your targeted device.
After this you get your build.xml and everything is in place for generating an apk.

ant debug install
is actually viable if you create project with (note that you should specify the virtual device with "adb -s" command while installing if you're running multiple devices)
android create project -n <project_name>
-t <target_version> -p <path> -k <package> -a <activity>
and use this command to run on the avd (if you've started one)
adb -e shell "am start -a android.intent.action.MAIN -n com.your.package/.YourActivity"
(change -e option to -d if you're running on devices)
reference
better use "AVD Manager.exe" to start a virtual device if you don't know those command or parameters, as there're quite a lot.

One of the best example I found on Internet for creating Android APK is https://geosoft.no/development/android.html.Also you can use assembleDebug command in root directory (make sure setting gradle as environment variable), if you are using Gradle.

cocos2d-2.0-rc2-x-2.0.1 Hello World sample doesn't work using cygwin on windows8

I am unable to build helloWorld sample to get .so to run it in eclipse. I have imported project successfully and changed variable to my root path as required. this is my build_native.sh. I am pasting the only change I made in that file
NDK_ROOT_LOCAL=/cygdrive/e/android-ndk-r8
COCOS2DX_ROOT_LOCAL=/cygdrive/e/cocos2d
And my NDK is working fine because I have executed HelloWorld sample of NDK successfully. My SDK version is 20 and NDK version is 8 and I am using cygwin above than 1.7.. I have executed the chown on my NDK directory.. But when I run the command ./build_native.sh in HelloWorld sample program for cocos2d I get this error
E:/android-ndk-r8/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/../lib/gcc/arm- linux-androideabi/4.4.3/../../../../arm-linux-androideabi/bin/ld.exe: ./obj/local/armeabi/png.a: No such file: Permission denied
collect2: ld returned 1 exit status
and when I search for png.a in my NDK directory window can't locate that file. I am confused whether it's a permission error or File isn't there. But I have the latest NDK if file isn't there how come anyone will able to run cocos2d-x??? Need Help!!!

It seems like the permissions on built files were missing when I tried as well.
$ ls -l obj/local/armeabi/png.a
---------- 1 someuser Domain Users 912618 Jul 12 18:23 obj/local/armeabi/png.a
There is a link suggested on the forum which doesn't seem to be accessible right now.
Anyway, to fix, you can set the permission on the files.
$ cd obj/local/armeabi/
$ chmod 664 *.a
$ cd ../../..
Edit: A better fix may be to set the default permissions in /etc/fstab to
none /cygdrive cygdrive binary,noacl,posix=0,user 0 0
Following this, you should be able to run ./build_native.sh.
A command you could use to locate all files below the current directory which have no (read/write) permission available on them is find . -type f -perm 0
See this answer to set write permissions on all files below your working directory.
Consider going through a tutorial on chmod to understand the concept of permissions in linux/unix in case you're unfamiliar with them.

android monkey runner scripts

i am tryig to execute a sample python program through monkey runner command prompt and it is throwing an error
Can't open specified script file
Usage: monkeyrunner [options] SCRIPT_FILE
-s MonkeyServer IP Address.
-p MonkeyServer TCP Port.
-v MonkeyServer Logging level (ALL, FINEST, FINER, FINE, CONFIG, INFO,
WARNING, SEVERE, OFF)
Exception in thread "main" java.lang.NullPointerException
so any one can guide me how to resolve this one

scriptfile should be a full path file name
try below
monkeyrunner c:\test_script\first.py

try using something like
...\tools>monkeyrunner -v ALL first.py
where first.py was my sample python script which I copied into tools folder of android SDK (the place where monkeyrunner.bat is located)

Under all unix/linux families OS the sha bang syntax can be used.
Edit the first line of your script with the results of the following command:
which monkeyrunner
for example, if monkeyrunner (usually provided with android sdk) has been installed under /usr/local/bin/sdk write:
#!/usr/local/bin/sdk/tools/monkeyrunner
or even use "env"
#!/usr/bin/env monkeyrunner
then set you script file as executable
chmod +x <script>
You can now launch your script from the shell.

It looks not make sense to switch working directory to Android SDK folder but just for obtain some relative references path for itself. It means you have to specify the full path for your script file and the PNG image files you want to save or compare to.
A better way is modify few lines in the "monkeyrunner.bat" under your SDK folder as below. This will use your current path as working directory, so, no necessary to use full path file name.
rem don't modify the caller's environment
setlocal
rem Set up prog to be the path of this script, including following symlinks,
rem and set up progdir to be the fully-qualified pathname of its directory.
set prog=%~f0
rem Change current directory and drive to where the script is, to avoid
rem issues with directories containing whitespaces.
rem cd /d %~dp0
rem Check we have a valid Java.exe in the path.

I met the same things as you did, I resolved by using "monkeyrunner" command under tools, and your script file should be a full path name. It looks like the directory “tools” is the main directory of MonnkeyRunner. I am depressed that I can't run my script files by pydev IDE directly.
