RxPermissions库搞定Android6.0权限

1、工具的github地址https://github.com/tbruyelle/RxPermissions

2、android studio中引用：

repositories {
    jcenter() // If not already there
}
dependencies { 
    compile 'com.tbruyelle.rxpermissions:rxpermissions:0.9.1@aar'
}

3在代码中的使用

一、用之前首先在BaseActivity中的onCreate中实例化 代码：RxPermissions rxPermissions = new RxPermissions(this);

二、在用到权限的地方进行申请
######申请单个权限
rxPermissions .request(Manifest.permission.CAMERA) 
.subscribe(granted -> {
 if (granted) { 
       // Always true pre-M // I can control the camera now
 } else { 
    // Oups permission denied
 }
 });

######申请多个权限
rxPermissions .request(Manifest.permission.CAMERA, Manifest.permission.READ_PHONE_STATE) 
.subscribe(granted -> {
 if (granted) { 
       //全部通过
      // All requested permissions are granted
 } else { 
     //有一个没通过
    // At least one permission is denied
 }
 });


######申请多个权限，分个
rxPermissions
    .requestEach(Manifest.permission.CAMERA,
             Manifest.permission.READ_PHONE_STATE)
    .subscribe(permission -> { // will emit 2 Permission objects
        if (permission.granted) {
           // `permission.name` is granted !
        } else if (permission.shouldShowRequestPermissionRationale)
           // Denied permission without ask never again
        } else {
           // Denied permission with ask never again
           // Need to go to the settings
        }
    });

注：现在很多手机厂商对android6.0的rom进行了定制修改，权限申请有的可能已经免了。
