Android最低SDK问题

Question

I have a function that I need to use, but I need to set my minimum SDK up to 23 in order to use it. Problem is, our application runs on a lot of lower SDK devices out there in the wild. Is there any way I can setup my project to allow me to compile the application while still using a lower minimum SDK target?

You need to set your compileSdkVersion to 23.

Set your minSdkVersion to whatever you want. Set your compileSdkVersion to 23 or higher. Then, make sure that you only call canDrawOverlays() on API Level 23+ devices, such as by checking Build.VERSION.SDK_INT .

Answer 2

Check that the api is 23 or greater before trying to call this function:

if (android.os.Build.VERSION.SDK_INT >= 23) {
    Settings.canDrawOverlays(this);
} else {
// I don't think you need to do anything, I believe canDrawOverlays is 
//functionally true for older APIs
}

Answer 3

Have you already had a look at the Supporting Different Platform Versions page?

If you want to use the method canDrawOverlays(...) on ALL platforms, then you simply can't: it's only supported in the API starting from version 23. However, if you want to use this api ONLY when the platform version >= 23 (meaning: only on those devices with AT LEAST Marshmallow installed), then you can:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.MARSHMALLOW) {
    Settings.canDrawOverlays(...)
}
