At a Glance

Convenience is a set of tools for making permissions management in Android significantly easier.

How to Get Started

Add jitpack.io repository to your project:

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

Then add Convenience to dependencies list:

dependencies {
    implementation 'com.github.igormatyushkin014:Convenience:2.0.1'
}

Requirements

• Android SDK 23 and later
• Android Studio 3.0 and later
• Java 7 and later

Usage

Permission Manager

All operations with permissions are done with PermissionManager instance which is available via:

PermissionManager permissionManager = Convenience.getPermissions();

Preparing Activity

Before using Convenience for permission request, you have to override activity's onRequestPermissionsResult method:

@Override
public void onRequestPermissionsResult(
    int requestCode,
    @NonNull String[] permissions,
    @NonNull int[] grantResults
) {
    boolean handledByConvenience = Convenience.getPermissions().onRequestPermissionsResult(
        requestCode,
        permissions,
        grantResults
    );

    if (!handledByConvenience) {
        super.onRequestPermissionsResult(
            requestCode,
            permissions,
            grantResults
        );
    }
}

Check Permissions

String[] permissions = new String[] {
    Manifest.permission.CAMERA,
    Manifest.permission.WRITE_EXTERNAL_STORAGE
};

Convenience.getPermissions().check(
    permissions,
    activity,
    new PermissionManager.OnRequestListener() {
        @Override
        public void onResult(CheckResult checkResult) {
            if (requestResult.hasBlockedPermissions()) {
                // Handle blocked permissions
            } else {
                // All permissions available
            }
        }
    }
);

CheckResult instance includes both allowed and blocked permissions:

String[] allowedPermissions = checkResult.getAllowedPermissions();
String[] blockedPermissions = checkResult.getBlockedPermissions();

Request Permissions

Ask user to accept permissions:

Convenience.getPermissions().request(
    permissions,
    activity,
    new PermissionManager.OnRequestListener() {
        @Override
        public void onResult(RequestResult requestResult) {
            if (requestResult.hasBlockedPermissions()) {
                // Handle blocked permissions
            } else {
                // All permissions available
            }
        }
    }
);

Also, you can request only those permissions from the list that are currently blocked. It means that, if the permissions list includes accepted permissions, they will not be requested again. User will be asked to accept other permissions that were not accepted before:

Convenience.getPermissions().requestIfNeeded(
    permissions,
    activity,
    new PermissionManager.OnRequestListener() {
        @Override
        public void onResult(RequestResult requestResult) {
            if (requestResult.hasBlockedPermissions()) {
                // Handle blocked permissions
            } else {
                // All permissions available
            }
        }
    }
);

RequestResult instance includes both allowed and blocked permissions:

String[] allowedPermissions = requestResult.getAllowedPermissions();
String[] blockedPermissions = requestResult.getBlockedPermissions();
