An error occurred with my app which ran in Nexus5 (Android6.0).

The error was

java.lang.RuntimeException: Fail to connect to camera service

I had added the permission to the AndroidManifest.xml.

But the app is OK with another phone(Android5.1), and genymotion AVD(Android 4.0).

The key code is below

 @Override
public void onResume() {
    super.onResume();
    try {
        mCamera = Camera.open();
    }catch (Exception e){
        Log.e(TAG,"open camera failed",e);
    }

}

  • Please add the whole Stacktrace. I guess you got a `SecurityException` as well which is an indicator that you didn't request the camera permission at runtime. – reVerse Oct 22 '15 at 14:22

Write in your gradle.build targetSdkVersion 22. It is a temporary solution but work.

  • This was also the solution for me. Very weird! What could be the cause? – Ilie Daniel Stefan Nov 19 '15 at 10:25

    It's not weird at all. API levels <=22 don't use run time permission, but 23 do. Check the link in zzzmode's answer. – c0dehunter Apr 15 '16 at 18:55

    Changing Target sdk to 22 is not a solution because it will still fail for android 6 devices, go for proper implementation with android 6 way follow this llink http://developer.android.com/training/permissions/requesting.html – Rahul Sonone Jun 09 '16 at 08:43
  • Instead of these apply runtime permission for get better result and you can also use this in above 6.0 – Savan Kachhiya Patel Nov 21 '16 at 10:33

open Settings -> Apps -> click you app -> Permissions -> open Camera permissions.
you can see: http://developer.android.com/training/permissions/requesting.html

This happens because, in Android 6.0 the permission model is different. You have to implement the new permission model which asks for the permission on run time. Even if you don't ask it, you can manually enable it in the phone's app setting, but that is not gona work when you publish your app in the play store. Here is an Article on How to get Run time permissions

Also you can check Nick's answer here for getting multiple permissions

From android 6.0 you can handle the app permission weather you will give or not specific permission for an application. In your case if you didn't enable camera permission for your app then this issues may arise.

So, you need to enable permission from settings->apps->your_app->enable camera permission.

  • You saved my day ! But, it seem that we have to ask for permissions explicitly as @Amalan Dhananjayan otherwise the final user will not be supposed to know some tricky things as settings->apps->your_app->enable camera – Houssem Oct 04 '16 at 15:03

    @Houssem Yes, you need to handle this programmatically. https://inthecheesefactory.com/blog/things-you-need-to-know-about-android-m-permission-developer-edition/en a good tutorial to do this. – 0xAliHn Oct 04 '16 at 18:33

Add Camera Permission before Opening the Camera:

follow the Link for adding Permissions: https://developer.android.com/training/permissions/requesting.html
