Android runtime permissions make easy

Why?

In marshmallow, android has introduced runtime permission check, that means when application runs, it asks user provide permission to run specific functionality. for example if you using Camera or saving files on external storage or location.

The android basic code to request permission is to complex and tedious to understand (if you don't trust me, check here 😃 ). Ask is a library make asking for the particular permission easy for developer. This is very simple and light weight library with just few lines of code and you good to go.

Demo( How it looks!)

Ask for permission Show rationale

How to use.

  • Very first step is to include this library in your project by adding following entry into your project's gradle dependencies
dependencies {
  compile 'com.vistrav:ask:2.5' 
}
  • Adding the necessary permissions into your project manifest file
  • Add the following code in your class to request the runtime permissions
import android.Manifest; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.util.Log;  import com.vistrav.ask.Ask; import com.vistrav.ask.annotations.AskDenied; import com.vistrav.ask.annotations.AskGranted;  @SuppressWarnings("unused") public class MainActivity extends AppCompatActivity {

private static final String TAG = MainActivity.class.getSimpleName();

@Override
  protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Ask.on(this)

  .id(INT_ID_OF_YOUR_REQUEST) // in case you are invoking multiple time Ask from same activity or fragment

  .forPermissions(Manifest.permission.ACCESS_COARSE_LOCATION

 , Manifest.permission.WRITE_EXTERNAL_STORAGE)

  .withRationales("Location permission need for map to work properly",

 "In order to save file you will need to grant storage permission") //optional

  .go();

  
}

//optional
  @AskGranted(Manifest.permission.WRITE_EXTERNAL_STORAGE)
  public void fileAccessGranted(int id) {

Log.i(TAG, "FILE  GRANTED");

  
}

//optional
  @AskDenied(Manifest.permission.WRITE_EXTERNAL_STORAGE)
  public void fileAccessDenied(int id) {

Log.i(TAG, "FILE  DENiED");

  
}

//optional
  @AskGranted(Manifest.permission.ACCESS_COARSE_LOCATION)
  public void mapAccessGranted(int id) {

Log.i(TAG, "MAP GRANTED");

  
}

//optional
  @AskDenied(Manifest.permission.ACCESS_COARSE_LOCATION)
  public void mapAccessDenied(int id) {

Log.i(TAG, "MAP DENIED");

  
}
 
}
 
  • The setting rationale message is optional but it would be good in case user has declined the permission, there is chance for developer to explain app user why specific permission is needed
  1. forPermissions method takes one or more permissions as argument
  2. withRationales method takes one or more rationale message, usually it is good to provide same number of rationale messages as number of permissions

IMPORTANT: If your application is running in any android verion lesser than Marshamallow, the all, requested permissions will be granted by default and you can find then in list provided by granted method

You can contribute!

In case you think you have some improvement, please feel free do pull request your feature and I would be happy to include it. Let's make this Ask very easy to use and rich with features.

WhirlyGlobe-Maply is a toolkit with two parts, hence the dash. The WhirlyGlobe part is an interactive 3D globe. The Maply part is an interactive 2D map. There are separate view controllers (on iOS) for each, but otherwise they share 95% of their code.

Parallax everywhere (PEW) is a library with alternative android views using parallax effects.

How it works?

  • Any parallax views (PEW*) needs to be inside a view with scroll events, ej: scrollView, listView, gridView....
  • Parallax effect on views will be related to its position on device screen.
  • Parallax effect in ImageView is calculated with left image in Scale mode centerCrop, centerInside or center. You can't make more parallax effect.
  • Parallax effect in no image views needs a size parallax parameter (read: Attributes)

The TileView widget is a subclass of ViewGroup that provides a mechanism to asynchronously display tile-based images, with additional functionality for 2D dragging, flinging, pinch or double-tap to zoom, adding overlaying Views (markers), built-in Hot Spot support, dynamic path drawing, multiple levels of detail, and support for any relative positioning or coordinate system.

FlowLayout is an opensource Android library that allows developers to easily integrate flow layout into their app. FlowLayout is an layout that display its children in multiple rows depending on their size.
