Nammu - Runtime Permission Helper

Speed up your work with new Runtime Permissions introduced in Android M. This lib allows you to monitor permissions, check them in background and as well ask for a permission in easy way.

###What are Runtime Permissions? Google docs is here. TLDR: like old-loved permissions that were ask during intallation but this time they are more dynamic (should be ask only when they are needed) and can be revoked by user at any time.

###Why should I care? Beacause your user can revoke most essential part of your app and quite probably there will be a lot of app crashes. Current solution you can see here - Google sample basically there is a lot that happens with Activity that is used to check and grant permissions. Also permissions rights are checked many times in the code.

###Easy asking for permissions It removes a bit of boiler plate to keep request id, and thus simplify your code inside Activity class. call Nammu.askForPermission(Activity, PermissionString , PermissionCallback) which offers a nice callback with either succes or fail method. To use this only thing you need to add is in your Activity that you are using.

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    Nammu.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

###Monitor permissions To keep track of access to particular permissions, all you need is init Nammu Nammu.init(Context); (can be in Application class onCreate or Activity) and add permissions to monitor such Nammu.savePermission(PermissionString); so for example Nammu.savePermission(Manifest.permission.CAMERA);.

After that each time you want to make sure if permissions are still there - Nammu.permissionCompare(PermissionListener); and PermissionListener will be called if some Permission was removed.

###Extras You can get list of monitored Persmissions -Nammu.getPrevPermissions(), removed some Nammu.removePermission(PermissionString), or check if is monitored Nammu.containsPermission(PermissionString).

###How to import it? As for now it is not hosted at Maven/JCenter etc. as it is based on preview build of Android M which SDK is not available on those platforms. Till that time, it is available on jitpack.io by adding this to your build.gradle:

repositories {
    maven {
        url "https://jitpack.io"
    }
}

dependencies {
    compile 'com.github.tajchert:nammu:0.4.5'
}

Kudos to Jitpack.io for installing M preview SDK for us(link)!
