android 有些手机没有权限 手机没有权限怎么办

在6.0以后的手机上出现了手动权限的问题，那么就需要使用到动态的权限问题。

首先要先知道是否有这个权限，也就是说要先进行权限判断：

方法一：

int permission1 = ContextCompat.checkSelfPermission(this,
                Manifest.permission.CALL_PHPNE);

首先获取权限开启值（以电话权限为例，其他权限相同），进行判断：

if (permission1 != PackageManager.PERMISSION_GRANTED) {}

如果permission1 != 0 就说命没有权限进行动态申请权限。

方法二：

if (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED
                    && permission1 != PackageManager.PERMISSION_GRANTED) {
            }

直接进行if判断是否该权限；

如果有则进行其他操作，如果没有则进行动态申请权限：

ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission.READ_PHONE_STATE, Manifest.permission.CALL_PHONE},
                        REQUEST_CODE_ASK_READ_PHONE_STATE);

@Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case REQUEST_CODE_ASK_READ_PHONE_STATE:
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Log.i("WelcomeActivity", "权限允许");

                    //判断游客token是否为空
                    if (MyApplication.TOKEN.equals("")) {
                        //进行游客登录
                        requestPost(UrlData.TOURIST_LOGIN, UrlData.getTouristLogin());
                    }
                    //开启handler
                    handler.sendEmptyMessageDelayed(1, 1000);
                } else {
                    Log.i("WelcomeActivity", "权限拒绝");
                    showFaiingDialog();
                    return;
                }
                return;
        }
    }
 private void showFaiingDialog() {
        new AlertDialog.Builder(this)
                .setTitle("权限申请")
                .setMessage("开启存储空间、电话、相机权限")
