# Fixing `route ip+net: netlinkrib: permission denied` in android
|
||||||
|
|
||||||
|
|
||||||
|
The details for this error can be seen in https://github.com/ipfs-shipyard/gomobile-ipfs/issues/68, and happens when targeting android API version +30. (`targetSdkVersion 30` in your `gradle.properties` / `build.gradle`) In this issue a possible solution was described which involved all the steps shown below. I have modified these to take in account that we are using +Go 1.18 as well as using a newer version of the Android NDK. These instructions should be used until https://github.com/golang/go/issues/40569 is fixed and a new gomobile version is released that includes this fix
|
||||||
|
|
||||||
|
|
||||||
|
### Installing the requirements to build go-waku for android
|
||||||
|
|
||||||
|
These instructions assume that you are running Ubuntu, have NodeJS installed, and don't have any of the go and android required software installed. `root` access is required. Paths containing `/home/YOUR_USER` are referenced in different places. Replace `YOUR_USER` with your username (obtained with `whoami`). Don't blindly copy/paste the commands (It's not a good practice anyway)
|
||||||
|
|
||||||
|
**Installing required dependencies**
|
||||||
|
```
|
||||||
|
sudo apt update
|
||||||
|
sudo apt install build-essential unzip openjdk-11-jdk
|
||||||
|
```
|
||||||
|
|
||||||
|
**Installing Go 1.18**
|
||||||
|
```
|
||||||
|
wget https://go.dev/dl/go1.18.6.linux-amd64.tar.gz
|
||||||
|
sudo rm -rf /usr/local/go
|
||||||
|
sudo tar -C /usr/local -xzf go1.18.6.linux-amd64.tar.gz
|
||||||
|
export PATH=$PATH:/usr/local/go/bin
|
||||||
|
```
|
||||||
|
|
||||||
|
**Installing the Android NDK 25**
|
||||||
|
```
|
||||||
|
mkdir -p /home/YOUR_USER/Android/Sdk/
|
||||||
|
wget https://dl.google.com/android/repository/android-ndk-r25b-linux.zip
|
||||||
|
unzip android-ndk-r25b-linux.zip
|
||||||
|
mv -r android-ndk-r25b /home/YOUR_USER/Android/Sdk/ndk
|
||||||
|
export ANDROID_NDK_HOME=/home/YOUR_USER/Android/Sdk/ndk
|
||||||
|
```
|
||||||
|
|
||||||
|
**Installing the Android SDK command line tools and android-30**
|
||||||
|
```
|
||||||
|
mkdir /home/YOUR_USER/Android/Sdk/cmdline-tools
|
||||||
|
wget https://dl.google.com/android/repository/commandlinetools-linux-8512546_latest.zip
|
||||||
|
unzip commandlinetools-linux-8512546_latest.zip
|
||||||
|
mv cmdline-tools /home/YOUR_USER/Android/Sdk/cmdline-tools/latest
|
||||||
|
export PATH=$PATH:/home/YOUR_USER/Android/Sdk/cmdline-tools/latest/bin
|
||||||
|
sdkmanager "platform-tools" "platforms;android-30"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Building go-waku for android
|
||||||
|
```
|
||||||
|
mkdir -p /home/YOUR_USER/go/src/github.com/waku-org
|
||||||
|
cd /home/YOUR_USER/go/src/github.com/status-im
|
||||||
|
git clone https://github.com/waku-org/go-waku
|
||||||
|
cd go-waku
|
||||||
|
echo "replace github.com/multiformats/go-multiaddr v0.7.0 => github.com/waku-org/go-multiaddr v0.0.0-20230105211400-b3bd508cf855" >> go.mod
|
||||||
|
export GO111MODULE=off
|
||||||
|
go get golang.org/x/mobile/cmd/gobind
|
||||||
|
go get golang.org/x/mobile/cmd/gomobile
|
||||||
|
export GO111MODULE=on
|
||||||
|
gomobile init
|
||||||
|
export GO111MODULE=off
|
||||||
|
gomobile bind -v -target=android -androidapi=23 -ldflags="-s -w" -v -o ./build/lib/gowaku.aar ./mobile
|
||||||
|
```
|
||||||
|
|
||||||
|
### Edit waku-react-native
|
||||||
|
```
|
||||||
|
mkdir -p /home/YOUR_USER/waku
|
||||||
|
cd /home/YOUR_USER/waku
|
||||||
|
git clone https://github.com/waku-org/waku-react-native
|
||||||
|
cd waku-react-native
|
||||||
|
npm install
|
||||||
|
./download-gowaku.sh
|
||||||
|
cp /home/YOUR_USER/go/src/github.com/waku-org/build/lib/gowaku.aar ./android/libs/.
|
||||||
|
```
|
||||||
|
|
||||||
|
### Edit your react-native project
|
||||||
|
**Edit packages.json**
|
||||||
|
Set `@waku/react-native` to the absolute path of your local copy of `waku-react-native` downloaded in the previous step
|
||||||
|
```json
|
||||||
|
...
|
||||||
|
"dependencies": {
|
||||||
|
"@waku/react-native": "file:/home/YOUR_USER/waku/waku-react-native/",
|
||||||
|
}
|
||||||
|
...
|
||||||
|
```
|
||||||
|
And execute `npm install` (or `yarn`) to link your local dependency
|
||||||
|
|
||||||
|
**Edit metro.config.js**
|
||||||
|
```js
|
||||||
|
const { getDefaultConfig } = require('expo/metro-config');
|
||||||
|
const exclusionList = require('metro-config/src/defaults/exclusionList');
|
||||||
|
const path = require('path');
|
||||||
|
|
||||||
|
const root = '/home/YOUR_USER/waku/waku-react-native/';
|
||||||
|
const pak = require(root + 'package.json');
|
||||||
|
|
||||||
|
module.exports = {
|
||||||
|
// ...
|
||||||
|
watchFolders: [root],
|
||||||
|
resolver: {
|
||||||
|
blacklistRE: exclusionList(
|
||||||
|
Object
|
||||||
|
.keys({...pak.peerDependencies})
|
||||||
|
.map(m => new RegExp(`^${escape(path.join(root, 'node_modules', m))}\\/.*$`))
|
||||||
|
),
|
||||||
|
extraNodeModules: new Proxy(
|
||||||
|
{},
|
||||||
|
{
|
||||||
|
get: (target, name) => {
|
||||||
|
if (target.hasOwnProperty(name)) {
|
||||||
|
return target[name]
|
||||||
|
}
|
||||||
|
return path.join(process.cwd(), `node_modules/${name}`)
|
||||||
|
},
|
||||||
|
},
|
||||||
|
),
|
||||||
|
},
|
||||||
|
}
|
||||||
|
```
|
||||||
|
If you're using `expo`, in `waku-react-native`'s example app, you can see an example configuration achieving the same result
|
||||||
|
|
||||||
|
**Edit your application `android/build.gradle`**
|
||||||
|
Add `gowaku.aar` to the list of dependencies
|
||||||
|
```js
|
||||||
|
...
|
||||||
|
dependencies {
|
||||||
|
|
||||||
|
implementation files("$rootDir/../node_modules/@waku/react-native/android/libs/gowaku.aar")
|
||||||
|
|
||||||
|
}
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
**Edit `MainApplication.java`**
|
||||||
|
|
||||||
|
```java
|
||||||
|
// Add the following imports
|
||||||
|
import go.Seq;
|
||||||
|

|
||||||

import java.util.List;
|
||||||
|
import java.util.Locale;
|
||||||
|
|
||||||
|
...
|
||||||
|
|
||||||
|
@Override
|
||||||
|
public void onCreate() {
|
||||||
|
// ...
|
||||||
|
|
||||||
|
// Add this line so that if RunOnJVM() with golang.org/x/mobile/app to call JAVA from GO,
|
||||||
|
// will not cause error "no current JVM"
|
||||||
|
Seq.setContext(getApplicationContext());
|
||||||
|
}
|
||||||
|
|
||||||
|
...
|
||||||
|
// Add this function
|
||||||
|
// To fix [x/mobile: Calling net.InterfaceAddrs() fails on Android SDK 30](https://github.com/golang/go/issues/40569)

try {

} catch (Exception e) {

return "";
|

|
||||||
|

||||||

StringBuilder sb = new StringBuilder("");
|
||||||

for (NetworkInterface nif : interfaces) {
|
||||||
|
try {
|
||||||
|
// Android doesn't have a supportsBroadcast() but the Go net.Interface wants
|
||||||
|
// one, so we say the interface has broadcast if it has multicast.
|
||||||
|
sb.append(String.format(java.util.Locale.ROOT, "%s %d %d %b %b %b %b %b |", nif.getName(),
|
||||||
|
nif.getIndex(), nif.getMTU(), nif.isUp(), nif.supportsMulticast(),
|

nif.isLoopback(), nif.isPointToPoint(), nif.supportsMulticast()));
|
||||||
|
|
||||||
|
for (InterfaceAddress ia : nif.getInterfaceAddresses()) {
|

|
// InterfaceAddress == hostname + "/" + IP
|
||||||

String[] parts = ia.toString().split("/", 0);
|
||||||

if (parts.length > 1) {
|

sb.append(String.format(java.util.Locale.ROOT, "%s/%d ", parts[1], ia.getNetworkPrefixLength()));
|

|

```
|

|
|

|
After this step, build your app. The error should have dissapeared.
|
||||||
|
In `adb logcat` you will see this message instead `avc: denied { bind } for scontext=u:r:untrusted_app` which seems to be due to Android restrictions which prevents Waku from obtaining the IP address of the device, but it will still be able to connect to other devices succesfully.
