My app needs below permissions. Which has been incorporated in AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>

<uses-permission android:name="android.permission.CAMERA"/>

<uses-feature android:name="android.hardware.camera"/>

<uses-feature android:name="android.hardware.autofocus"/>

After upgrading to API 26

(targetSdkVersion 26)

Some functionality is not working. As I need to incorporate runtime permission. I am using RxPermission .
The problem is my most of the implementations are placed in helper class(not inside main activity).
when I am trying to use helper library getting error - .
I have tried with the following options too -

RxPermissions rxPermissions = new RxPermissions((FragmentActivity) mContext);

As RxPermission require Fragment as target.Can we ask user all the permission in the main activity? A sample code will help me. Project code for reference

[Fixed]
Now I am calling from the activity. ReferenceCode changed -

RxPermissions rxPermissions=new RxPermissions(this);

rxPermissions.request(Manifest.permission.CAMERA)

        .subscribe(granted -> {

            if (granted) {



                //LogUtil.e(LOG_TAG, "Granted external permission");

                setContentView(R.layout.activity_local_album);

                ViewGroup backGround = (ViewGroup) findViewById(R.id.background);

                MyUtil.setBackgroundBlur(backGround, this);



                initAdapter();

                assignViews();



            } else {

                // Oups permission denied

            }

        });

[New error]
I am getting android.os.FileUriExposedException: error. Code:

public void onClick(View v) {

    switch (v.getId()) {

        // 返回

        case R.id.action_back:

            myFinish();

            break;

        // 拍照

        case R.id.action_capture:

            PackageManager pm = getPackageManager();

            // FEATURE_CAMERA - 后置相机

            // FEATURE_CAMERA_FRONT - 前置相机

            if (pm.hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY)) {

                // 访问相机类型

                int requestType;

                // 截取主题壁纸

                if (mRequestType != 2) {

                    requestType = REQUEST_IMAGE_CAPTURE_THEME;

                } else { // 截取二维码logo

                    requestType = REQUEST_IMAGE_CAPTURE_QRCODE_LOGO;

                }



                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                mImageUri = Uri.fromFile(MyUtil.getFileDirectory(this, "/Android/data/" +

                        getPackageName() + "/capture/temporary.jpg"));

                intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);

                startActivityForResult(intent, requestType);

                overridePendingTransition(0, R.anim.zoomin);

            }

My app needs below permissions

Note that your app cannot hold MOUNT_UNMOUNT_FILESYTEMS unless it is signed by the firmware signing key or is installed on the privileged app partition (mostly for rooted devices).

Can we ask user all the permission in the main activity?

You do not have a choice, according to the documentation. According to those instructions, RxPermissions only works if you request the permissions from onCreate() of your Activity (or possibly onCreate() of your Fragment, though that part is unclear).

A sample code will help me

In addition to documentation, the RxPermissions GitHub repository has a sample app. Here is the v0.9.3 edition of that sample app.

Finally I am able to fix it calling from main class.

 RxPermissions rxPermissions=new RxPermissions(this);

    rxPermissions.request(Manifest.permission.READ_EXTERNAL_STORAGE)

            .subscribe(granted -> {

                if (granted) {

                    customDefineBtn.setOnClickListener(this);

                    LogUtil.e(LOG_TAG, "Granted external permission");



                } else {

                    // Oups permission denied

                }

            });
