I can't find the Android denpendencies

[relaxbao]

sorry， i can't find the following dependencies , how should I get them ? looking forward for your reply~ thank you very much!

implementation project(':react-native-community-netinfo')
implementation project(':@react-native-community_async-storage')
implementation project(':react-native-share')
implementation(project(':react-native-firebase')) {
    transitive = false
}
implementation project(':react-native-navigation')
implementation project(':react-native-device-info')
implementation project(':rn-fetch-blob')
implementation project(':react-native-vector-icons')
implementation project(':react-native-passcode-android')
implementation project(':react-native-randombytes')
implementation project(':react-native-image-picker')
implementation(project(':react-native-camera')) {
    exclude group: "com.google.android.gms"
    exclude group: "com.facebook.infer.annotation"
}
implementation project(':react-native-intent-launcher')

implementation project(':react-native-uport-signer')

The Android setup depends on the javascript environment setup so please follow that.

Essentially, make sure to run yarn install after you clone

@mirceanis thank you very much , but there still are some problems , after I did the following steps

>npm install yarn -g
>yarn global add react-native-cli
>yarn

i still can't find the dependencies

implementation project(':react-native-community-netinfo')
implementation project(':@react-native-community_async-storage')
implementation project(':react-native-share')
....

when I ran yarn start,it's blocking.

➜  uport-mobile git:(develop) yarn start
yarn run v1.17.3
$ node node_modules/react-native/local-cli/cli.js start

Looking for JS files in
   /Users/baolinfang/workspace/uport/uport-mobile

Loading dependency graph, done.

should I run yarn start? wiil I ultimately get the dependencies in the files ?

[mirceanis]

That is expected behavior. What you started is a local server that can serve the debug react native bundle to the app on an emulator or connected device.

If you intend to run the app, it's easier with react-native run-android

If you only care about the dependencies, they are in node_modules. Look in android/settings.gradle for the path to each one.

@relaxbao thank you very much ^^ it works~ but i have another question --!

did we use ethr-did-registry or ethr-did or ethr-did-resolver in the uport-mobile? if we did , why i can't find it ？i searched it globally， such as the function lookupOwner .

[mirceanis]

ethr-did is not used directly. ethr-did-registry@0.0.3 and ethr-did-resolver@0.2.0 are used either directly or as dependencies of other libs.

I can't tell why you haven't found any result in your search. Make sure you run the search after running yarn install

[relaxbao]

@mirceanis thank you so so much ~! yes, i have ran yarn install, I can only find it in the yarn.lock , but ethr-did-registry was not imported .

actually ,i can use the app now , but i want to debug it , can I debug it on the browser ? it's an easy way to debug ~

because I want to know how we create the did and register it on the contract , especially where do we create the did document and combine it to a did so that we can get the publicKey.

[mirceanis]

ERC1056 describes ethr-did-registry. The key point is that fresh identities do not have to be registered onto the registry. The registry is modified only when a DID operation needs to be executed (change owner, add or revoke a delegate, or some other property)

The DID document is not combined into a DID, it is the other way around. A DID is resolved into a DID document (in this case using the ethr-did-resolver)

In the ethr DID context, the DID document does not exist as a file, it is constructed by the ethr-did-resolver while resolving a given DID based on events regarding the ethereumAddress of that ethr-did in the registry. If there are no events for a given ethereumAddress, then a default DID document is returned where the public key entry is the ethereum address itself.

To create an ethr-did from an ethereumAddress, you prepend the string did:ethr: to the ethereum address.

[relaxbao]

@mirceanis wow~ it helps me a lot , I think I understand it better , you're so amazing ~ as we can derive the public key from ethereumAddress and it's signature, so we don't need to combine a DID to a document . we just need to resolve it from the DID。

other attributes were in the events of the contract (deployed by the ethr-did-registry). am I right ?

I will read the ERC1056 again , thank you so much ~!

[relaxbao]

@mirceanis hello ,

I have deeply read the ERC1056, but there is something I can't understand , can you help me ?

for example : I have an ethereum account ,as mentioned in the ERC1056 , I have naturally have an identity right ? I don't need to register on the registry contract .

but if I don't register on the registry contract ,how can I get the public Key ? because an important feature of DID is to get the public Keyfrom the DID, so we can use the public Key to encrypted something .
