Expo 54 - Android - mulitple build errors

[philippelef]

Custom HTTP maven repository is causing issues.

* What went wrong:
Could not determine the dependencies of task ':app:processDebugResources'.
> Could not resolve all dependencies for configuration ':app:debugRuntimeClasspath'.
   > Could not find me.bridgefy:android-sdk:1.2.3.

I tried using expo plugins to allow the insecure custom maven repository without success. It seems you can't override that setting using the more recent versions of Expo/Gradle.

My build settings

[ExpoRootProject] Using the following versions:
  - buildTools:  36.0.0
  - minSdk:      26
  - compileSdk:  36
  - targetSdk:   36
  - ndk:         27.1.12297006
  - kotlin:      2.1.20
  - ksp:         2.1.20-2.0.1

temporary fix was to use a https proxy server but that's really hacky.

Current solution to build on Expo 54 is the following:

1st Plugin - Add the bridgefy Api KEY in the AndroidManifest.xml:

./plugins/add-bridgefy-api-key.ts

import {
  AndroidConfig,
  ConfigPlugin,
  withAndroidManifest,
} from "expo/config-plugins";

const withAndroidPlugin: ConfigPlugin = (config) => {
  return withAndroidManifest(config, (config) => {
    const mainApplication = AndroidConfig.Manifest.getMainApplicationOrThrow(
      config.modResults,
    );

    AndroidConfig.Manifest.addMetaDataItemToMainApplication(
      mainApplication,
      "com.bridgefy.sdk.API_KEY",
      process.env.EXPO_PUBLIC_BRIDGEFY_API_KEY!,
    );

    return config;
  });
};

export default withAndroidPlugin;

./plugins/add-maven-proxyts

import { ExpoConfig } from "expo/config";
import { withProjectBuildGradle } from "expo/config-plugins";

/**
 * Adds a local maven proxy after the jitpack repository in project build.gradle.
 */
export default function withCustomAppBuildGradle(config: ExpoConfig) {
  return withProjectBuildGradle(config, async (config) => {
    const jitpackPattern =
      /maven\s*\{\s*url\s*['"]https:\/\/www\.jitpack\.io['"]\s*\}/;

    const mavenProxyBlock = `
    maven {
      url "..." <-- replace with your custom proxy url
    }
      `;

    if (config.modResults.contents.match(jitpackPattern)) {
      config.modResults.contents = config.modResults.contents.replace(
        jitpackPattern,
        (match) => `${match}${mavenProxyBlock}`,
      );
    }

    return config;
  });
}

./plugins/add-syntax-desugar (Taken from here: expo/expo#31071 (comment))

import { ExpoConfig } from "expo/config";
import { withAppBuildGradle } from "expo/config-plugins";

export default function withCustomAppBuildGradle(config: ExpoConfig) {
  return withAppBuildGradle(config, async (config) => {
    const androidPattern = "\nandroid {\n";
    const androidIndex = config.modResults.contents.indexOf(androidPattern);
    const androidPivot = androidIndex + androidPattern.length + 1;
    config.modResults.contents =
      config.modResults.contents.slice(0, androidPivot) +
      "   compileOptions {\n        coreLibraryDesugaringEnabled true\n    }\n\n " +
      config.modResults.contents.slice(androidPivot);

    const dependenciesPattern = "\ndependencies {\n";
    const dependenciesIndex =
      config.modResults.contents.indexOf(dependenciesPattern);
    const dependenciesPivot =
      dependenciesIndex + dependenciesPattern.length + 1;
    config.modResults.contents =
      config.modResults.contents.slice(0, dependenciesPivot) +
      '   coreLibraryDesugaring("com.android.tools:desugar_jdk_libs:2.1.4")\n\n ' +
      config.modResults.contents.slice(dependenciesPivot);

    return config;
  });
}

in your expo config file:

{
   ...,
   plugins: [
    ["./plugins/add-bridgefy-api-key.ts"],
    ["./plugins/add-syntax-desugar.ts"],
    ["./plugins/add-maven-proxy.ts"],
]
}

[antoinerousseau]

add-bridgefy-api-key.ts could be integrated into this repo as an official Expo plugin

add-maven-proxy.ts should be fixed/replaced by #47

add-syntax-desugar.ts could be removed if the desugaring is done directly in this lib

[antoinerousseau]

fyi I also had to add this plugin to fix the permissions:

import { ExpoConfig } from "expo/config";
import { AndroidConfig, withAndroidManifest } from "expo/config-plugins";

export default function withFixedAndroidManifestPermissions(_config: ExpoConfig) {
  return withAndroidManifest(_config, (config) => {
    const { manifest } = config.modResults;
    manifest.$["xmlns:tools"] = "http://schemas.android.com/tools";

    for (const permission of manifest["uses-permission"]!) {
      if (
        permission.$["android:name"] ===
        "android.permission.ACCESS_BACKGROUND_LOCATION"
      ) {
        permission.$["tools:node"] = "remove";
      }
    }

    manifest["uses-permission-sdk-23"] = [
      {
        $: {
          "android:name": "android.permission.ACCESS_COARSE_LOCATION",
          "tools:node": "remove",
        },
      },
      {
        $: {
          "android:name": "android.permission.ACCESS_FINE_LOCATION",
          "tools:node": "remove",
        },
      },
    ];

    return config;
  });
}

and add them properly to the expo app config under the android key:

    permissions: [
      "android.permission.ACCESS_COARSE_LOCATION",
      "android.permission.ACCESS_FINE_LOCATION",
      "android.permission.BLUETOOTH_SCAN",
      "android.permission.BLUETOOTH_CONNECT",
      "android.permission.BLUETOOTH_ADVERTISE",
    ],
