The following devices were found:

macOS (desktop) • macos • darwin-x64 • macOS 13.1 22C65 darwin-x64

and it shows the device ID of my Android phone is `61106679`, so I use

```bash

┌─ Flutter Fix ───────────────────────────────────────────────────────────────────────────────────────────────────┐
|
||||
│ The plugin record_android requires a higher Android SDK version. │
|
||||
│ Fix this issue by adding the following to the file │
|
||||
│ /Users/fangjun/open-source/sherpa-onnx/flutter-examples/streaming_asr/android/app/build.gradle: │
|
||||
│ android { │
|
||||
│ defaultConfig { │
|
||||
│ minSdkVersion 23 │
|
||||
│ } │
|
||||
│ } │
|
||||
│ │
|
||||
│ │
|
||||
│ Following this change, your app will not be available to users running Android SDKs below 23. │
|
||||
│ Consider searching for a version of this plugin that supports these lower versions of the Android SDK instead. │
|
