What is TedPermission?

After the update to Android 6.0 Marshmallow, we have to not only declare permissions in AndroidManifest.xml, but also request them at runtime. Furthermore, user can on/off permissions in application setting anytime.
When you use dangerous permissons(ex. CAMERA, READ_CONTACTS, READ_PHONE_STATE, ...), you must check and request them runtime.
( http://developer.android.com/intl/ko/guide/topics/security/permissions.html#normal-dangerous)

You can make your own permission check logic like this, but it's so complex and hard to use functions Google offers: checkSelfPermission(), requestPermissions(), onRequestPermissionsResult(), onActivityResult().

TedPermission makes it easy to check and request android permissions.

Demo



  1. Request Permissions.
  2. If user denied permissions, we will show message dialog with Setting button.

Setup

Gradle

Edit root/app/build.gradle like below.

Normal

dependencies {

  compile 'gun0912.ted:tedpermission:2.1.0' 
}

RxJava1

dependencies {

  compile 'gun0912.ted:tedpermission-rx1:2.1.0' 
}

RxJava2

dependencies {

  compile 'gun0912.ted:tedpermission-rx2:2.1.0' 
}

How to use

Normal

-Make PermissionListener

We will use PermissionListener for Permission Result. You will get result to onPermissionGranted(), onPermissionDenied()

 PermissionListener permissionlistener = new PermissionListener() {

@Override

public void onPermissionGranted() {

 Toast.makeText(MainActivity.this, "Permission Granted", Toast.LENGTH_SHORT).show();

}

 @Override

public void onPermissionDenied(ArrayList<String> deniedPermissions) {

 Toast.makeText(MainActivity.this, "Permission Denied\n" + deniedPermissions.toString(), Toast.LENGTH_SHORT).show();

}

 
}
;

-Start TedPermission

TedPermission class requires setPermissionListener(), setPermissions(), and check() check() will start to check permissions.

setRationaleMessage() and setDeniedMessage() are optional methods.

 TedPermission.with(this)
  .setPermissionListener(permissionlistener)
  .setDeniedMessage("If you reject permission,you can not use this service\n\nPlease turn on permissions at [Setting] > [Permission]")
  .setPermissions(Manifest.permission.READ_CONTACTS, Manifest.permission.ACCESS_FINE_LOCATION)
  .check();



RxJava1

If you use RxJava1, You can use request() method instead check() When Permission check finish, you can receive tedPermissionResult instance. tedPermissionResult instance has isGranted(), getDeniedPermissions()

 TedRxPermission.with(this)

.setDeniedMessage(

 "If you reject permission,you can not use this service\n\nPlease turn on permissions at [Setting] > [Permission]")

.setPermissions(Manifest.permission.READ_CONTACTS, Manifest.permission.ACCESS_FINE_LOCATION)

.request()

.subscribe(tedPermissionResult -> {

  if (tedPermissionResult.isGranted()) {

 Toast.makeText(RxJava1Activity.this, "Permission Granted", Toast.LENGTH_SHORT).show();

  
}
 else {

 Toast.makeText(RxJava1Activity.this,

  "Permission Denied\n" + tedPermissionResult.getDeniedPermissions().toString(), Toast.LENGTH_SHORT)

  .show();

  
}

}
, throwable -> {

}
, () -> {

}
);
 



RxJava2

Also RxJava2 can use request() like RxJava1

 TedRx2Permission.with(this)

.setRationaleTitle(R.string.rationale_title)

.setRationaleMessage(R.string.rationale_message) // "we need permission for read contact and find your location"

.setPermissions(Manifest.permission.READ_CONTACTS, Manifest.permission.ACCESS_FINE_LOCATION)

.request()

.subscribe(tedPermissionResult -> {

  if (tedPermissionResult.isGranted()) {

 Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show();

  
}
 else {

 Toast.makeText(this,

  "Permission Denied\n" + tedPermissionResult.getDeniedPermissions().toString(), Toast.LENGTH_SHORT)

  .show();

  
}

}
, throwable -> {

}
, () -> {

}
);

Customize

TedPermission support this method

  • setGotoSettingButton(boolean) (default: true)
  • setRationaleTitle(R.string.xxx or String)
  • setRationaleMessage(R.string.xxx or String)
  • setRationaleConfirmText(R.string.xxx or String) (default: confirm / ??)
  • setDeniedTitle(R.string.xxx or String)
  • setDeniedMessage(R.string.xxx or String)
  • setDeniedCloseButtonText(R.string.xxx or String) (default: close / ??)
  • setGotoSettingButtonText(R.string.xxx or String) (default: setting / ??)

Also you can use util function.

  • isGranted(Context context, String... permissions): Check permissions all granted
  • isDenied(Context context, String... permissions): Check permissions all denied
  • getDeniedPermissions(Context context, String... permissions)
  • canRequestPermission(Activity activity, String... permissions): If true you can request system popup, false mean user checked Never ask again
  • startSettingActivityForResult(Activity activity)
  • startSettingActivityForResult(Activity activity, int requestCode)



Number of Cases

  1. Check permissions -> have permissions
    : onPermissionGranted() called

  2. Check permissions -> don't have permissions
    : show request dialog

  3. show request dialog -> granted permissions
    : onPermissionGranted() called

  4. show request dialog -> denied permissions
    : show denied dialog

  5. show denied dialog -> close
    : onPermissionDenied() called

  6. show denied dialog -> setting
    : startActivityForResult() to setting activity

  7. setting activity -> onActivityResult()
    : check permission

  8. check permission -> granted permissions
    : onPermissionGranted() called

  9. check permission -> denied permissions
    : onPermissionDenied() called
