All samples run fine (or have no need to be tested as MWE's) on my Lollipop phone.\r\n\r\nThe trouble comes with my backup phone which is running on build number A820_S150_Lambda_v2.4. That's a modded ROM from stock S150 API16. Which obviously I should try reverting back to before tearing up source code. It's ironic that Native Activity is working fine, is exactly what I want/need and yet was removed from the samples in the 3.0 release. It just works, and discourages me from flashing a stock ROM.\r\n\r\nAlso, though you might assume this already, the Color Blob Detector sample is responding to touch and showing the orange-yellow in the top left (after touch) and also a square to the left of that representing the color touched.\r\n\r\nThe logcat's are fine, the SDK manager is fine, either 3.0 or 2.4.10 have the same result in 2.4.x apk's. This appies to 2.4 and 3.0 samples."},"comment":{"url":"https://api.github.com/repos/Itseez/opencv/issues/comments/141944171","html_url":"https://github.com/Itseez/opencv/issues/5374#issuecomment-141944171","issue_url":"https://api.github.com/repos/Itseez/opencv/issues/5374","id":141944171,"user":{"login":"alalek","id":4981219,"avatar_url":"https://avatars.githubusercontent.com/u/4981219?v=3","gravatar_id":"","url":"https://api.github.com/users/alalek","html_url":"https://github.com/alalek","followers_url":"https://api.github.com/users/alalek/followers","following_url":"https://api.github.com/users/alalek/following{/other_user}","gists_url":"https://api.github.com/users/alalek/gists{/gist_id}","starred_url":"https://api.github.com/users/alalek/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/alalek/subscriptions","organizations_url":"https://api.github.com/users/alalek/orgs","repos_url":"https://api.github.com/users/alalek/repos","events_url":"https://api.github.com/users/alalek/events{/privacy}","received_events_url":"https://api.github.com/users/alalek/received_events","type":"User","site_admin":false},"created_at":"2015-09-21T11:12:17Z","updated_at":"2015-09-21T11:12:17Z","body":"Native camera support was dropped in 3.0, because there are no important benefits on modern Android devices.\r\n\r\n> Also, though you might assume this already, the Color Blob Detector sample is responding to touch and showing the orange-yellow in the top left (after touch) and also a square to the left of that representing the color touched.\r\n\r\nDoes this mean that Camera API works and problem with drawing image?"}}
