Flutter run fails when an activity-alias is used in the Android manifest #80532
Description
Explanation
When using an <activity-alias> in the AndroidManifest.xml the command futter run is unable to build the app (I guess because it cannot find the activity in the manifest).
<activity-alias> in the AndroidManifest.xml is for example typically used in the case of an app-update where the name of the launcher activity (e.g. MainActivity) has changed (e.g. NewMainActivity). It seems that flutter run cannot handle this and fails to build/run the app.
More info on the activity-alias tag in the AndroidManifest can be found here
Sample project:
See https://github.com/PieterAelse/flutter_android_activity_alias_issue .
And specifically this commit where the activity-alias changes are highlighted.
Steps to Reproduce
- Create a new flutter project using
flutter create - Try
flutter runwith an Android device attached/emulated, it will succeed. - Add an
<activity-alias>for the used Activity and remove the<intent-filter>used as launcher for the Activity itself (otherwise you'll see 2 launcher icons when installing the app). - Try
flutter runwith an Android device attached/emulated, it will fail with the error:
package identifier or launch activity not found.

Is your project missing an android/app/src/main/AndroidManifest.xml?
Consider running "flutter create ." to create one.

The issue is "fixed" when some build data is already there, for example when running
flutter build apk --debugand thenflutter run.Example build and then run output
But, after running
flutter cleanyou will again run into the error when usingflutter run..TahaTesser commentedon Apr 16, 2021
