index.android.bundle missing in APK after upgrading to RN 0.68

After upgrading our RN app to RN 0.68, we are getting errors with the release build:
FATAL EXCEPTION: create_react_context
Process: com.app, PID: 15057
java.lang.RuntimeException: Unable to load script. Make sure you're either running Metro (run 'npx react-native start') or that your bundle 'index.android.bundle' is packaged correctly for release.
The app works fine in development, and was fine before upgrading. It is using Hermes, but not using the new Fabric architecture.
When building the APK and then looking into its content, we can see that the bundle is not copied. But it is correctly built in the intermediate artifacts:
$ ./gradlew assembleRelease

I am suspecting that there is a missing build step and it is not copied to the final directory, but I am not familiar enough with Gradle or RN's build process to check this.
Do you have any idea of what can cause this, or where to look at to troubleshoot this?

Found it after comparing the build files with a brand new RN app!
I had
classpath("com.android.tools.build:gradle:7.1.2")
in android/build.gradle
But with RN 0.68, you need to depend exactly on version 7.0.4, otherwise the JS bundle is not copied into the final APK.
The release APK is now working after switching to
classpath("com.android.tools.build:gradle:7.0.4")

Android CI using Bitbucket Pipelines and Docker

I am trying to set up Continuous Integration (CI) in Bitbucket Pipelines for Android.
I have created a sample blank activity using Android Studio 2.1.1.
With Pipelines I'm using the uber/android-build-environment Docker container which creates the environment nicely. Here is my bitbucket-pipelines.yml
image: uber/android-build-environment:latest
pipelines:
default:
- step:
script:
- echo y | android update sdk --filter "extra-android-m2repository" --no-ui -a # Grab the Android Support Repo which isn't included in the container
- ./gradlew assembleDebug
Some changes are needed since uber/android-build-environment is expecting to be run like so:
docker run -i -v $PWD:/project -t uber/android-build-environment /bin/bash /project/ci/build.sh
For example, the source is not copied to the volume /project but instead Pipelines copies the contents of the Bitbucket repo to the working directory of the container at:
/opt/atlassian/bitbucketci/agent/build
And when ./gradlew assembleDebug is run I get the following error:
...
FAILURE: Build failed with an exception.
* What went wrong:

It's a bug in their system , I report it(issue url, it's quite long) to them and they have fixed it (fix url).I have tested on my project and it successfully build.Try to build your project now and good luck.

It looks like uber/android-build-environment is not supported anymore.
I ended up using javiersantos/android-ci instead which works perfectly from scratch.
Just add the following content to bitbucket-pipeline.yml:
image: javiersantos/android-ci:27.0.3
pipelines:
default:
- step:
script:
- export GRADLE_USER_HOME=`pwd`/.gradle
- chmod +x ./gradlew
- ./gradlew assembleDebug

Could you symlink your project from /opt/atlassian/bitbucketci/agent/build to /project from within the container? ln -s /opt/atlassian/bitbucketci/agent/build /project is the command you'll need.
or alternatively copy the files to the new path?
I have no experience with android development, so YMMV :)

zipalign: error while loading shared libraries: libc++.so: cannot open shared object file: No such file or directory

I am trying to build android app. When I run the zip align tool to optimize the APK, I get this error message:
zipalign: error while loading shared libraries: libc++.so: cannot open shared object file: No such file or directory
I tried to install libc++
sudo aptitude install libc++
it says: Couldn't find package "libc+".
Snapshot of my terminal

If your system is 64-bits, there should be a folder lib64 on the path of
[android-path]/build-tools/[version]/
The files in lib64 are
[ec2-user 25.0.2]$ ll lib64/
total 51628
-rwxrwxrwx 1 ec2-user ec2-user 30712616 Dec 23 07:22 libLLVM.so

Just copy the folder lib64 and zipalign program together to the destination path, and you can run the zipalign correctly. It worked for me. I guess the zipalign has a dependency on the files in lib64 folder.

I met the same problems and google it. You can try the following suggestions:
If you are in 64-bit environment, try: sudo apt-get install lib32stdc++6 lib32z1 lib32z1-dev.
Update the latest android sdk tools and do not move the zipalign binary to any other folder. It solve my problem.

I had the exact same problem and it was probably because I moved the zipalign binary from <android-path>/build-tools/23.0.3 to <android-path>/tools.
The solution is to add the build-tools/23.0.3 dir to your path:
export PATH=${PATH}:<android-path>/build-tools/23.0.3

Build Android project on command line on OSX: Task 'assembleDebug' not found in root project

I'm trying to build Android projects on the OSX (Mavericks 10.9.5) command line using this how-to: http://developer.android.com/tools/building/building-cmdline.html.
This How-To explains the use of assembleDebug/assembleRelease to build an Android project.
Unfortunately gradle doesn't create the assembleDebug or assembleRelease targets.
Executing ./gradlew assembleDebug returns this:
FAILURE: Build failed with an exception.
* What went wrong:
Task 'assembleDebug' not found in root project 'test'.
* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

What am I missing to be able to build an Android project on the command line?

android create project does not create a gradle friendly structure. It creates an ant friendly structure. You have two options depending on your intentions.
use ant to build your project ( not currently supported by Android team )
use Android Studio to generate a gradle friendly project structure.
num 2 is the recommended approach by the Android team. It's as simple as dl'ing Android Studio and creating a new project. From there you should be able to create a new project that can be built with ./gradlew build

try This:
./android create project -p AppPAKTGV -a Main -k com.example.apppaktgv -t android-23 -g -v 0.11.+
it's works but when i try target 24 or 25 not work i don't now

Try to do this and note
a) you need to type tools/android under Step 3 (like step 2: Execute)
-- but as said the ant structure is not helpful
-- not sure I can go from there
b) I follow the advice and also ensure get the platform-tools
-- I can build
-- I can get that .apk
-- I can adb install (I rename any existing .apk)
Seems working!

Gradle Error 2 in Android project even file exists

I've generated android project with gradle support in IntelliJ. I have arch linux, on my friend's computer who has Windows everything is ok. On my computer I cannot build project, I get following error:
Error:Gradle: Execution failed for task ':app:mergeDebugResources'.

What am I doing wrong?

I needed to install 32bit version of libc++ and other applications.
