自从Android在6.0引入动态权限，各种坑接踵而来，今天有时间专门整理一下动态权限的那些事。

一、动态权限基本知识

 group:android.permission-group.CONTACTS    permission:android.permission.WRITE_CONTACTS    permission:android.permission.GET_ACCOUNTS        permission:android.permission.READ_CONTACTS  group:android.permission-group.PHONE    permission:android.permission.READ_CALL_LOG    permission:android.permission.READ_PHONE_STATE     permission:android.permission.CALL_PHONE    permission:android.permission.WRITE_CALL_LOG    permission:android.permission.USE_SIP    permission:android.permission.PROCESS_OUTGOING_CALLS    permission:com.android.voicemail.permission.ADD_VOICEMAIL  group:android.permission-group.CALENDAR    permission:android.permission.READ_CALENDAR    permission:android.permission.WRITE_CALENDAR  group:android.permission-group.CAMERA    permission:android.permission.CAMERA  group:android.permission-group.SENSORS    permission:android.permission.BODY_SENSORS  group:android.permission-group.LOCATION    permission:android.permission.ACCESS_FINE_LOCATION    permission:android.permission.ACCESS_COARSE_LOCATION  group:android.permission-group.STORAGE    permission:android.permission.READ_EXTERNAL_STORAGE    permission:android.permission.WRITE_EXTERNAL_STORAGE  group:android.permission-group.MICROPHONE    permission:android.permission.RECORD_AUDIO  group:android.permission-group.SMS    permission:android.permission.READ_SMS    permission:android.permission.RECEIVE_WAP_PUSH    permission:android.permission.RECEIVE_MMS    permission:android.permission.RECEIVE_SMS    permission:android.permission.SEND_SMS    permission:android.permission.READ_CELL_BROADCASTS

以上是需要动态申请的权限，一共9组，每组只要一个申请成功，这个组的权限默认就可以使用了。

申请的前提条件：

1.targetSdkVersion >= 23(废话)
2.在AndroidManifest.xml中申请

申请权限：

1.checkSelfPermission() 检查是否有此权限，没有则申请，有了直接可以向下执行
2.shouldShowRequestPermissionRationale() 这个是被拒绝后再次申请权限时对用户的解释，我基本不用此方法
3.requestPermissions() 申请权限，弹出一个对话框，用户是否允许开启此权限

举个例子：

private static final int STORAGE_CODE = 1;private void requestStoragePermission() {        if ((ActivityCompat.checkSelfPermission(mContext, Manifest.permission.READ_EXTERNAL_STORAGE)                != PackageManager.PERMISSION_GRANTED)){//无此权限，申请            ActivityCompat.requestPermissions(MainActivity.this,                    new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE},                    STORAGE_CODE);        }else {           //已经拥有此权限 } }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        super.onRequestPermissionsResult(requestCode, permissions, grantResults);         if (requestCode == STORAGE_CODE) {            int grantResult = grantResults[0];            boolean granted = grantResult == PackageManager.PERMISSION_GRANTED;            if (granted) {                //申请权限同意            } else {               //申请权限拒绝了            }        }     }

二、动态权限的坑
1.申请扫描附近的wifi，需要申请位置权限
2.有两个特殊的权限，SYSTEM_ALERT_WINDOW和WRITE_SETTINGS和以上介绍的权限申请有所区别，这俩权限需要开启一个页面，让用户打开权限，不是弹出窗！！
开启热点就需要WRITE_SETTINGS这个权限，上例子

private final static int REQUEST_CODE = 1;private void requestWriteSettingPermission() {        if (!Settings.System.canWrite(this)) {            Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS,                    Uri.parse("package:" + getPackageName()));            startActivityForResult(intent, REQUEST_CODE);        }    }    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        if (requestCode == REQUEST_CODE) {            if (Settings.System.canWrite(this)) {                //WRITE_SETTINGS permission granted            } else {                //WRITE_SETTINGS permission not granted            }        }    }

步骤：

1.使用Action Settings.ACTION_MANAGE_WRITE_SETTINGS 启动隐式Intent
2.使用"package:" + getPackageName()携带App的包名信息
3.使用Settings.System.canWrite方法检测授权结果

另外：申请SYSTEM_ALERT_WINDOW权限的话第三步使用Settings.canDrawOverlays()判断就好了

如果觉得帮助，欢迎打赏！
