Android(安卓)permission第三方rxpermission的正确使用姿势

之前的permission申请都是用的原生封装，现在接触下第三方的权限请求框架.
使用姿势:
1.Gradle引入

allprojects {    repositories {        ...        maven { url 'https://jitpack.io' }    }}dependencies {    implementation 'com.github.tbruyelle:rxpermissions:0.10.2'}

2.在AndroidManifest中声明权限:

3.在activity(fragment)的oncreate方法中使用,申请权限，注意的是申请的权限需要在androidmanifest中有对应的声明：

 RxPermissions rxPermissions = new RxPermissions(this);        Disposable subscribe = rxPermissions                .requestEachCombined(Manifest.permission.CAMERA,                        Manifest.permission.WRITE_EXTERNAL_STORAGE,                        Manifest.permission.ACCESS_FINE_LOCATION)                .subscribe(permission -> {                    if (permission.granted) {                        // All requested permissions are granted                        showToast("权限获取成功");                        Log.d("lwp","success permission:"+permission.name);                        // AppSp appSp = new AppSp(this, "", 1);                        String string = SPUtils.getInstance().getString(Constant.TOKEN);                        //testApkUpdate();                        try {                            if (isStringEmpty(string)) {                                Observable.timer(1000, TimeUnit.MILLISECONDS).subscribe(new Consumer() {                                    @Override                                    public void accept(Long aLong) throws Exception {                                        toLogin();                                    }                                });                            } else {                                Observable.timer(1000, TimeUnit.MILLISECONDS).subscribe(new Consumer() {                                    @Override                                    public void accept(Long aLong) throws Exception {                                        toMain();                                    }                                });                            }                        } catch (Exception e) {                            e.printStackTrace();                        }                    } else if (permission.shouldShowRequestPermissionRationale){                    // At least one denied permission without ask never again                                     } else {            // At least one denied permission with ask never again            // Need to go to the settings                              }                });
