主要的activity

從上面的AndroidManifest.xml中可以看到，主要包括的activity：

CameraActivity
PermissionsActivity
CaptureActivity
VideoCamera
SecureCameraActivity
CameraSettingsActivity
ImageEditControlActivity
以及部分ucamera中的activity，這裡不做分析

不同activity的主要功能

1. CameraActivity

相機的主介面，我們通過launcher進入camera後，展現給我們的相機預覽，錄影預覽介面。後面會詳細分析。此處暫時pass

2.PermissionsActivity

顧名思義，主要是為了設定許可權的介面。
關於PermissionsActivity的呼叫：
在CameraActivity.java中，在進入相機時，系統會首先check 許可權是否ok。
