问题描述

这里发生的是调用裁剪图片活动，然后相机活动在后台运行。当我完成这个活动，相机仍然活着的背景。那么如何以编程方式杀掉在后台运行的摄像机活动？

What happens here is I call the crop image activity and then the camera activity runs in background. When I finish this activity, the camera is still alive at the background. So how can I kill programmatically the camera activity running in background?


Intent newIntent = new Intent
newIntent.setAction（com.android.camera.action.CROP）;

newIntent.setClassName（com.android.gallery，com.android.camera.CropImage） ;

newIntent.setData（selectedImage）;
startActivityForResult（newIntent，IMAGE_CROP


推荐答案

当它需要更多的内存，它会杀死未使用的进程，如果你自己杀了，你也有风险杀死，而用户使用它，导致一个坏的用户体验。

You should let Android handle process lifecycle on its own. When it'd need more memory, it'll kill unused processes. If you kill it yourself, you also risk killing it while the user is using it leading to a bad user experience.
