Hey I am designing an app in android studio. In which i require permission of camera. I have included <uses-permission android:name="android.permission.CAMERA" /> in the the AndroidManifest.xml file. It is working properly in all versions of android except Marshmallow. How do I get camera permission by default? If not possible how do I ask it from user?

推荐答案

先检查用户是否授予权限:

First check if the user has granted the permission:

if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA)
    == PackageManager.PERMISSION_DENIED)

然后，您可以使用它向用户请求:

Then, you could use this to request to the user:

ActivityCompat.requestPermissions(activity, new String[] {Manifest.permission.CAMERA}, requestCode);

而在 Marshmallow 中，它会出现在一个对话框中

And in Marshmallow, it will appear in a dialog
