在Android 6.0（SDK 23）中检查自定义权限

Question

I have a few questions regarding how 'custom' permissions work in Android 6.0 with the new runtime permissions. For instance, a declared custom permission like this.

<permission android:description="com.mycompany.myapp.DEADLY_ACTIVITY"
        android:label="string resource"
        android:name="string"
        android:protectionLevel="dangerous" />

I could not find any information online that specify how to handle this type of custom permissions at runtime in Android M.

Should I handle and check "com.mycompany.myapp.DEADLY_ACTIVITY" permission in methods at runtime the same way I check dangerous android perimissions(camera, calendar etc.) with checkSelfPermission()? and provide rationale per Google's new standards?

Many Thanks!

Yes. You can check the permission with the ContextCompat.checkSelfPermission method using the permission name you declared in the manifest. So if you declared this in the manifest:

<permission android:description="com.mycompany.myapp.DEADLY_ACTIVITY"
    android:label="string resource"
    android:name="com.mycompany.myapp.permissionName"
    android:protectionLevel="dangerous" />

then you can check the permission anywhere in the app with this:

if(ContextCompat.checkSelfPermission(context, "com.mycompany.myapp.permissionName") == PackageManager.PERMISSION_GRANTED
