Camera Activity not found?

问题:

I've released an app and in the logs, I'm getting this message several times

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.MAIN pkg=com.android.camera } 

I'm calling the camera like this

final Intent mainCameraIntent = new Intent();
mainCameraIntent.setPackage("com.android.camera");
mainCameraIntent.setAction("android.intent.action.MAIN");
startActivity(mainCameraIntent);

Why am getting this message? On my device (2.3.3), it works fine. I had issues with 2.1 devices before and also with proguard removing blocks of code, but I'm not sure if this is related to any of those

Because you should not be using this Intent. Not all devices will have com.android.camera.
