• Android6.0动态权限申请步骤以及需要注意的一些坑


    因为工作需要,简单研究了一下Android6.0权限申请,在Google提供的sample的基础上,写了一个简单的demo。算是自己的笔记吧,可能会比较混乱,主要是方便以后查看。后期有别的问题,随时更新~

    • 本demo github下载地址!!!
    • Google提供的demo的下载地址
    • 6.0权限的基本知识,以下是需要单独申请的权限,共分为9组,每组只要有一个权限申请成功了,就默认整组权限都可以使用了。

    申请步骤

      1. 将targetSdkVersion设置为23,注意,如果你将targetSdkVersion设置为>=23,则必须按照Android谷歌的要求,动态的申请权限,如果你暂时不打算支持动态权限申请,则targetSdkVersion最大只能设置为22.
    • 2 在AndroidManifest.xml中申请你需要的权限,包括普通权限和需要申请的特殊权限。

    • 3.开始申请权限,此处分为3部。

      • (1)检查是否由此权限checkSelfPermission(),如果已经开启,则直接做你想做的。

      • (2)如果未开启,则判断是否需要向用户解释为何申请权限shouldShowRequestPermissionRationale。

      • (3)如果需要(即返回true),则可以弹出对话框提示用户申请权限原因,用户确认后申请权限requestPermissions(),如果不需要(即返回false),则直接申请权限requestPermissions()。
        (这里是一部门代码,底部有比较完善的代码,整个demo可以在github中下载)。

    6.0以下系统的应用程序安装界面.png

    备注!!!

    (1)checkSelfPermission:检查是否拥有这个权限
    (2)requestPermissions:请求权限,一般会弹出一个系统对话框,询问用户是否开启这个权限。
    (3)shouldShowRequestPermissionRationale:Android原生系统中,如果第二次弹出权限申请的对话框,会出现“以后不再弹出”的提示框,如果用户勾选了,你再申请权限,则shouldShowRequestPermissionRationale返回true,意思是说要给用户一个 解释,告诉用户为什么要这个权限。然而,在实际开发中,需要注意的是,很多手机对原生系统做了修改,比如小米,小米4的6.0的shouldShowRequestPermissionRationale 就一直返回false,而且在申请权限时,如果用户选择了拒绝,则不会再弹出对话框了。。。。 所以说这个地方有坑,我的解决方法是,在回调里面处理,如果用户拒绝了这个权限,则打开本应用信息界面,由用户自己手动开启这个权限。
    (4)每个应用都有自己的权限管理界面,里面有本应用申请的权限以及各种状态,即使用户已经同意了你申请的权限,他也随时可以关闭

    一次申请多个权限

    其实和申请一个权限是一样的,只是requestPermissions(final @NonNull Activity activity,
    final @NonNull String[] permissions, final int requestCode),里面的permissions给的参数多些而已。


    申请多个权限.png
     /**
         * 一次申请多个权限
         */
        public static void requestMultiPermissions(final Activity activity, PermissionGrant grant) {
    
            final List<String> permissionsList = getNoGrantedPermission(activity, false);
            final List<String> shouldRationalePermissionsList = getNoGrantedPermission(activity, true);
    
            //TODO checkSelfPermission
            if (permissionsList == null || shouldRationalePermissionsList == null) {
                return;
            }
            Log.d(TAG, "requestMultiPermissions permissionsList:" + permissionsList.size() + ",shouldRationalePermissionsList:" + shouldRationalePermissionsList.size());
    
            if (permissionsList.size() > 0) {
                ActivityCompat.requestPermissions(activity, permissionsList.toArray(new String[permissionsList.size()]),
                        CODE_MULTI_PERMISSION);
                Log.d(TAG, "showMessageOKCancel requestPermissions");
    
            } else if (shouldRationalePermissionsList.size() > 0) {
                showMessageOKCancel(activity, "should open those permission",
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                ActivityCompat.requestPermissions(activity, shouldRationalePermissionsList.toArray(new String[shouldRationalePermissionsList.size()]),
                                        CODE_MULTI_PERMISSION);
                                Log.d(TAG, "showMessageOKCancel requestPermissions");
                            }
                        });
            } else {
                grant.onPermissionGranted(CODE_MULTI_PERMISSION);
            }
    
        }
    • 关于权限请求结果的回调。Activity实现ActivityCompat.OnRequestPermissionsResultCallback接口,重写onRequestPermissionsResult方法。

       @Override
        public void onRequestPermissionsResult(final int requestCode, @NonNull String[] permissions,
                                               @NonNull int[] grantResults) {
            PermissionUtils.requestPermissionsResult(this, requestCode, permissions, grantResults, mPermissionGrant);
      
        }
