Android RxPermissions使用チュートリアル

github: https://github.com/tbruyelle/RxPermissions demo: https://github.com/anymyna/android_laboratory
手順:
1、初期化

dependencies {
    implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'
    implementation 'io.reactivex.rxjava2:rxjava:2.1.0'
    implementation 'com.github.tbruyelle:rxpermissions:0.10.2'

}

2、使い方
権限があるかどうかを検出

        RxPermissions permissions = new RxPermissions(this);
        permissions.setLogging(true);
        Log.d(TAG, "checkPermissionsIsGranted WRITE_EXTERNAL_STORAGE " + permissions.isGranted(Manifest.permission.WRITE_EXTERNAL_STORAGE));

個々の権限の申請

                RxPermissions permissions = new RxPermissions(RxPermissionsActivity.this);
                permissions.setLogging(true);
                permissions.request(Manifest.permission.CAMERA)
                        .subscribe(new Consumer<Boolean>() {
                            @Override
                            public void accept(Boolean aBoolean) throws Exception {
                                Log.d(TAG, "text_camera aBoolean " + aBoolean);
                            }
                        });

複数の権限の申請

                RxPermissions rxPermissions = new RxPermissions(RxPermissionsActivity.this);
                rxPermissions.requestEach(Manifest.permission.READ_SMS)
                        .subscribe(new Consumer<Permission>() {
                            @Override
                            public void accept(Permission permission) throws Exception {
                                if (permission.granted) {
                                    //          
                                    Log.d(TAG, "text_sms granted" );
                                    //result.agree(permission);
                                } else if (permission.shouldShowRequestPermissionRationale) {
                                    //         ，    『    』（Never ask again）,         ，            
                                    //result.refuse(permission);
                                    Log.d(TAG, "text_sms shouldShowRequestPermissionRationale" );
                                } else {
                                    //         ，    『    』，          
                                    //result.noMoreQuestions(permission);
                                    Log.d(TAG, "text_sms " );
                                }
                            }
                        });
