React-native-code-push: Staging release of app crashes immediately after opening

[greena13]

Solution: See comments below.

Update: After resetting the emulator completely and building again I no longer get the error about being unable to locate the bundle hash. The logs just say _Loading JS bundle from "assets://index.android.bundle"_ and then the app crashes.

Update 2: This seems to function correctly when building a production build, but not a staging one. They should be effectively the same, so I am not sure what is different at this stage.

I have followed the installation instructions on the Readme and my MainActivity.java looks like this:

package com.mypackage;

import android.app.Application;

import com.facebook.react.ReactApplication;
import com.microsoft.codepush.react.CodePush;
import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.react.shell.MainReactPackage;


import java.util.Arrays;
import java.util.List;

public class MainApplication extends Application implements ReactApplication {
  private CodePush _codePush;

  private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {

    @Override
    protected boolean getUseDeveloperSupport() {
      return BuildConfig.DEBUG;
    }

    @Override
    protected String getJSBundleFile() {
      return _codePush.getJSBundleFile("index.android.bundle");
    }

    @Override
    protected List<ReactPackage> getPackages() {
      _codePush = new CodePush(BuildConfig.CODEPUSH_KEY, MainApplication.this, BuildConfig.DEBUG);

      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          _codePush
      );
    }
  };

  @Override
  public ReactNativeHost getReactNativeHost() {
      return mReactNativeHost;
  }
}

I have added the codepush.gradle to app/build.gradle

apply from: "../../node_modules/react-native/react.gradle"
apply from: "../../node_modules/react-native-code-push/android/codepush.gradle"

After creating a staging bundle

 code-push release-react <appName> Staging

I built a staging APK

cd android && ./gradlew assembleStaging

Which successfully builds a staging build variant (deployment key omitted)

 staging {
        ...
        applicationIdSuffix ".staging"         
        buildConfigField "String", "CODEPUSH_KEY", '"<KEY>"'
    }

I then installed it on an Android emulator

./gradlew installStaging

But when I open up the app on the emulator, it immediately crashes. So I viewed the debug log using

 code-push debug android

And opened (not resumed) the app again and I see the following output

Loading JS bundle from "assets://index.android.bundle"
Unable to get the hash of the binary's bundled resources - "codepush.gradle" may have not been added to the build definition.

I checked the release history using

 code-push deployment ls

And it shows No installs recorded for the Staging deployment.

I am using:

code push CLI 1.12.3-beta
code push 1.8.0-beta
react-native-code-push 1.14.1-beta
react-native 0.29.2

This ended up being an issue with React Native. It seems react.gradle expects all release variants to have the phrase release in them, otherwise it builds it as a development build. This caused my app to crash. By renaming my _staging_ variant to _stagingRelease_ and running

./gradlew assembleStagingRelease

It builds the release APK, but pointed at the _Staging_ CodePush deployment, like I want. It's then just a matter of installing the APK on the device or emulator

./gradlew installStagingRelease

And confirming from the logs and release history that it is indeed retrieving bundles from the Staging deployment.

Thanks for the issue and update @greena13, this is helpful!

@greena13 Hi I have the same error but I didn't understand how to fix it? can you describe your solution please?

[greena13]

@SimchaShats edit your app/build.gradle's buildTypes and ensure any release or staging builds end in release or Release, eg stagingRelease. Otherwise, Gradle will not create the release bundle of your application. There is something incompatible with CodePush when it is built for release and when React still has all its debugging and development configuration turned on.

[SimchaShats]

Can you show your whole build.grdale file, please?

@greena13 It worked like a charm. Thanks @greena13.
Saved my day girl! Thanks a million.

@greena13 can you show us the snippet of build.gradle file.
