Code Review

This pull request updates the Android device launch detection to fail when the am start command output contains "Error type " in addition to "Error: ", and adds a corresponding unit test. The reviewer feedback suggests extending this logic to also catch security exceptions (such as "Security exception") using a regular expression, and adding a test case to verify this behavior.

Comment thread packages/flutter_tools/lib/src/android/android_device.dart Outdated
- Enhance am start output verification in AndroidDevice.startApp using a case-insensitive RegExp to catch 'Security exception' errors alongside 'Error:'.
- Because am start returns 0 on security exceptions, this prevents infinite hangs waiting for the VM service port when starting restricted activities.
- Add new unit test verifying graceful abort when am start returns a security exception.
