I am trying to zipalign an “input.apk” file on an Ubuntu 14.04 LTS system using the command line as I do not have access to the source code just yet. If I’m not mistaken I should be able to do this with the following command
zipalign [-f] [-v] 4 intput.apk output.apk
but I am getting the following output
zipalign: command not found
I have made sure that the zipalign file is in my …sdk/tools directory which I had to copy over from my …build-tools/android-4.4W folder because it was originally missing. When I input this line as suggested in another question
./zipalign [-f] [-v] 4 intput.apk output.apk
I get the following output
Zip alignment utility Copyright (C) 2009 The Android Open Source Project Usage: zipalign [-f] [-v] <align> infile.zip outfile.zip zipalign -c [-v] <align> infile.zip <align>: alignment in bytes, e.g. '4' provides 32-bit alignment -c: check alignment only (does not modify file) -f: overwrite existing outfile.zip -v: verbose output
Does this mean that I need a .zip file instead of my .apk to zipalign?
When a usage message contains an argument in brackets, the brackets mean that that argument is optional and can be left out of the final command; the brackets are not themselves part of the command syntax.
In your case, correct usage might look like:
./zipalign -v 4 intput.apk output.apk
cd /opt/android-sdk/build-tools/21.1.2 sudo ln -sf zipalign /usr/bin/ zipalign -v 4 platforms/android/ant-build/MainActivity-release-unsigned.apk platforms/android/ant-build/YOUR_APP.apk
- Open terminal (CTRL + t)
- cd YOUR_PATH/android-sdk-linux/build-tools/XX.X.X
- sudo cp zipalign /usr/bin/
- Open the folder where is located your apk in the terminal.
- Execute zipalign -v 4 YOUR_APK.apk YOUR_APK.apk
I had the same issue. This is how i solved it, all you need is here.
1. Get zipalign path by getting sdk path on android studio. which is
/Users/s****/Library/Android/sdk for me.
2. Paste the path on your terminal and cd to “build-tools/28.0.3/zipalign” now command will be
3. zip the apk on the same command line by adding
-v 4 app-release-unsigned.apk my.apkto the command, now command will be
/Users/s****/Library/Android/sdk/build-tools/28.0.3/zipalign -v 4 app-release-unsigned.apk my.apk
