Question

超图读取本地许可需要动态申请权限？

Answer 1

您好，需要获取权限来读取许可的，您可以用该方法结合androidmanifest.xml获取到动态权限

private void requestPermissions() { //Android6.0以上设备设置动态权限
    if (Build.VERSION.SDK_INT >= 23) {
        // 检查是否拥有权限
        String[] permissions = {
                Manifest.permission.WRITE_EXTERNAL_STORAGE,
                Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.READ_PHONE_STATE,
                Manifest.permission.ACCESS_WIFI_STATE,
                Manifest.permission.ACCESS_NETWORK_STATE,
                Manifest.permission.CHANGE_WIFI_STATE,
        };
        String permission = null;
        int id = 0;
        boolean isBreak = false;
        int checkCallPhonePermission = 0;
        for (int i = 0; i < permissions.length; i++) {
            permission = permissions[i];
            checkCallPhonePermission = checkSelfPermission(permission);
            if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED) {
                requestPermissions(permissions, id);
                isBreak = true;
                break;
            }
        }
    }

}

另外，看您的报错是空指针，建议build.gradle文件中compileSdkVersion与targetSdkVersion都改为28再运行
