It appears, based on https://code.janeasystems.com/nodejs-mobile/faq#are-nodejs-native-modules-supported and #121 native modules are only supported using nodejs-mobile-cordova and nodejs-mobile-native-react projects. I will try using cordova. |

Install cordova 7 using This following steps fail: Later versions of gradle do not try to build mips version based on google/filament#15 (comment) To fix I updated the build tools gradle version to New error is that there is an old version of gradle, but the gradle distribution urls were edited. What can overwrite these and how do I update them? Updating the wrapper.properties again seems to work.

Task :BuildNpmModulesarmeabi-v7a fails with npm command. ~/git/janeasystems/nodejs-mobile-samples-one/cordova/UseNativeModules/platforms/android$ ./gradlew assembleDebug --stacktrace |

Here's the debug of same. It's too many characters for a comment, so I've added a gist. ./gradlew assembleDebug --debug https://gist.github.com/algorist-mechanism/3e2195ad810f6efb5dfa1f7a03b8da6f#file-gistfile1-txt |

Here's build environment for same |

So perhaps it's node and npm are not available to gradle. So it tried the following from But I get the same error. |

Hi @algorist-mechanism , I have the same opinion: that gradle is unable to call npm on your machine. Perhaps it's because of the Building the native libraries for use in native applications is not currently supported. They currently have to be cross-compiled for Android. The gradle file in the plugins can be looked at to understand how this is achieved: https://github.com/janeasystems/nodejs-mobile-cordova/blob/be459ac4702a825a9254be03fc9448a5487436db/src/android/build.gradle#L206-L242 |

Hi @algorist-mechanism , @jaimecbernardo , I try pouchdb version 7.0.0 and I have the same issue: UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: dlopen failed: cannot locate symbol "napi_create_external" referenced by "/data/data/com.yourorg.sample/files/nodejs-project/node_modules/pouchdb/node_modules/leveldown/prebuilds/android-arm/node-napi.node"... Have you solved this problem?

Hi @bavuvanet , For native modules, you'd need to rebuild them linking against the nodejs-mobile shared libraries, otherwise they won't be correctly link at runtime on Android. (more information in JaneaSystems/nodejs-mobile-gyp#4 ) A possible method of achieving this is implemented in the cordova and react-native plugins. |

i fix similar issue by copy older ndk files to current ndk folder older ndk from https://developer.android.com/ndk/downloads/older_releases This time i tried ndk 21, 20, 19, 18, 17, and 16. And only error message
