![]() ![]() Your Android app permissions to cleartext Similar arguments can be provided to most webservers.Īn alternative might be to disable some unused adapters, especially virtual ones such as VPNs. The -host 0.0.0.0 instructs the webserver to serve all interfaces. To make it work, I had to use ng serve -disable-host-check -host 0.0.0.0 instead of just ng serve, as suggested in this other question. You need to read your local server's documentation to broaden permissions.įor example, in my case, my server was angular-cli (AngularJS), which by default restricts serving only to localhost. ![]() If it works, then this confirms that your local server is restricting access to some interfaces. Then, try to access this simple server from your emulator's Chrome browser, eg. ![]() To check this, try to use another server, just a simple HTTP server will do, such as http-server with nodejs, or python -m rver 8000 with Python 3. In case your web app can be accessed from your host computer, but not inside the emulator, the root cause can be that your local server is restricting access to some interfaces for some reason, likely for security reasons. If not, then test the other steps below to pinpoint the root issue. If your web app shows up, great, you're done. Open Chrome browser, and point it to : (for genymotion, replace with :). Check if your server is accessible from the emulator If not, then you likely have an issue with your local server parameters. Simply open a web browser and type to see if your local web app is accessible. If not, then you have another issue, maybe changing proxy settings can fix your issue, see here how to do that with Android Studio since 2022, as the proxy setting is now hidden away: How to configure proxy in emulators in new versions of Android Studio? Check if your server is accessible from your host computer Inside the emulated Android, go to Settings > WiFi, check if it is connected to AndroidWiFi hotspot (which represents your host computer), and then click on Advanced at the bottom, then check the Gateway address: it should point to 10.0.2.2. If the same is happening to you, here is a step-by-step guide to try to debug and hopefully fix your issue. $HOME/Android/Sdk/emulator/emulator -avd Pixel_3a_API_30_x86 > /dev/null 2>&1ĭespite reading all the answers here and elsewhere, I have lost several hours trying to debug this issue, as the address 10.0.2.2 did not work, even in Chrome browser. Hence, a bash script to launch an Android emulator, followed by a reverse proxy, would look like this: #!/usr/bin/env bash Whereas PWA installation is not allowed from IP address 10.0.2.2.Ĭaveat: adb reverse tcp:8000 tcp:8000 needs to be reissued after each Android emulator evocation. Or 127.0.0.1:8000 will be installable and connect to its service-worker.js. 8000) of the localhost server running on your host computer and vice versa: $ adb reverse tcp:8000 tcp:8000Ī progressive web application (PWA) being served on localhost:8000 Only then, configure a reverse proxy on the bridge of the Android emulator that will forward localhost HTTP requests to the appropriate port (e.g. Start your Android emulator as usual, e.g.: $ ~/Android/Sdk/emulator/emulator -avd Pixel_3a_API_30_x86 First of all, install the Android debug bridge: $ sudo apt install adb android-sdk-platform-tools-common ![]()
