Android API 23+ 動態權限申請

 final List<String> permissionsList = new ArrayList<>(); //需要申請的權限列表
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){ //判斷版本號是否大於23
            if ((checkSelfPermission(Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED)) //判斷該權限是否獲得授權
                permissionsList.add(Manifest.permission.READ_PHONE_STATE);

            if ((checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED))
                permissionsList.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);

            if (permissionsList.size() == 0){
                init(); //初始化
            }else{
                requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                        REQUEST_PHONE_PERMISSIONS); //進行權限申請
            }
        }else{
            init();
        }

複寫回調方法。

@Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case REQUEST_PHONE_PERMISSIONS:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    init();
                } else {
                    Toast.makeText(this, getString(R.string.need_permission),Toast.LENGTH_SHORT).show();
                    finish();
                }
                break;
            default:
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }
