We will check if the permissions are denied by creating the following method. You will open these method and we will create a for loop as follows. We open the For loop and we write the following logic. We will check if the permissions are granted or not. We access the string array of the permissions, and we are pointing to the element I. Which means they are granted.
As you can see we have a warning right here on the check self permissions line which says call requires API level 23, but we will be calling this only in API level 23, so we can ignore this by clicking in this warning sign, and then suppress link new API annotation. We click on that and this line is added and now, the warning is gone. We will continue right now and after the user checks or clicks on allow or deny permission what we have to do is get the result of that permission.
If the user allowed it or denied. To do that, we will do the following. We will override public void onRequestPermissionsResult. Inside this, we have some parameters that are passed. The first one will be an int which will pass the requestCode. So you can say int requestCode. The second one will be a string array and we have the permissions we were asking for. So, permissions and we also have an int array that will return the results of those permissions. So we can call it grantResults.
So the first one will be requestCode then will be permissions, and then will be grantResults. Now, we can make our lives easier by using the previous method, we wrote which is arePermissionsDenied, so we will check it right here. If that permission is a must the app cannot work without it. So if the user denies the permission we want to clear the application data, and close the app which will enable us to keep asking for the permission every time the user opens the app again.
To accomplish that, we will do the following. We will open two parentheses and the first one we will write ActivityManager. Outside the first one, we will create another parenthesis. Inside these second parenthesis, we will type this. We go after the three parentheses and we type. We then type clearApplicationUserData.
The first record is when the user denies activity, and when the user allows the permission, we want to call the onResume method because in that method we will do all the initialization. M which means marshmallow. If this statement is true, we also will check if the permissions are denied. So we call the method. If those two conditions are true we will request for permissions. Right now, we have our basic kind of app that ask permission so to check that everything works as we want, we will run the application to check if it actually works as expected.
If the user clicks on deny then the app is closed and the application data is cleared. If the user goes again on the music player application it asks again. So the user can keep denying, and keep opening the app. The user can keep opening the app. Basically what we did in this tutorial is we setup the Android studio project, we simplified the layout file, we simplified the Gradle build file, and we are requesting the permissions in the Android manifest, and also on code.
