We hope that flipper works well out of the box, but the software is a work in progress and problems will occur. Below are some known issues and steps you can take to try to resolve them.
|
|
|
|
## Mac Desktop app
|
|
|
|
### Flipper won't launch
|
|
|
|
* If the window is appearing, try opening the Chrome DevTools within Flipper. To do so, from the View menu select Toggle Developer Tools or press CMD+Option+I and check if there are any errors on the console.
|
|
* Launch Flipper from the command line using `/Applications/Flipper.app/Contents/MacOS/Flipper`. This should give you some logs, that might be helpful when debugging.
|
|
* Delete `~/.flipper` and try relaunching Flipper.
|
|
* Delete Flipper from your applications folder and redownload [Flipper](https://www.facebook.com/fbflipper/public/mac).
|
|
* If you're using `yarn start` to run from source, make sure all dependencies are installed correctly by running yarn install.
|
|
|
|
### iOS Simulator missing from devices dropdown
|
|
|
|
* Check that `xcode-select -p` shows the same XCode version that you're using. If not, see xcode-select for how to select the correct version.
|
|
|
|
### No plugins showing up for your device
|
|
|
|
* Check your device isn't on the list of [known incompatibilities](#known-incompatibilities).
|
|
* Make sure your version of Flipper is up to date.
|
|
* Make sure the mobile SDK you are using is relatively recent (<1 month old).
|
|
* Open Chrome dev tools within Flipper. To do so, from the View menu select Toggle Developer Tools or press CMD+Option+I and check if there are any errors on the console.
|
|
* Delete `~/.flipper`.
|
|
* **Uninstall** and reinstall the mobile app.
|
|
* Make sure the time and date are set correctly on your mobile device and desktop computer.
|
|
* If no app plugins are showing up, there may be a connectivity issue between Flipper and your app. Check [connection issues](#connection-issues) to see if anything is failing.
|
|
|
|
### Connection Issues
|
|
The Flipper SDK includes an in-app connection diagnostics screen to help you diagnose problems.
|
|
|
|
#### Android
|
|
Replace `<APP_PACKAGE>` below with the package name of your app, e.g. `com.facebook.flipper.sample`.
|
|
On a terminal, run the following:
|
|
```bash
|
|
adb shell am start -n <APP_PACKAGE>/com.facebook.flipper.android.diagnostics.FlipperDiagnosticActivity
|
|
```
|
|
This will only work if you added `FlipperDiagnosticActivity` to your `AndroidManifest.xml`. See [getting started](getting-started.html) for help.
|
|
|
|
#### iOS
|
|
You'll need to manually add this [ViewController](https://github.com/facebook/flipper/blob/master/iOS/FlipperKit/FlipperDiagnosticsViewController.m) to your app to see the in-app diagnostics.
|
|
|
|
### Known Incompatibilities
|
|
The following devices are known to be incompatible or face issues with flipper:
|
|
* Physical iOS devices. Currently on iOS, only simulators are supported ([Tracking Issue](https://github.com/facebook/flipper/issues/262)).
|
|
* Some Samsung devices ([Tracking Issue](https://github.com/facebook/flipper/issues/92)).
|
|
* Genymotion emulators on Android 8+ are reported to have issues.
|
|
|
|
### File an Issue
|
|
