TypeError: Cannot read property 'checkSelfPermission' of undefined

[sido420]

I did not find sample usage details in demo app.

There is no existing issue related to this.

• Android (not tested on iOS)

• Android 8.1.0

• ASUS Zenphone

• CLI: 6.7.8

• Cross-platform modules: "6.5.0"

• Runtime(s): 6.5.0 (both)

• Plugin(s): let me know if needed

Here is code example:

import { getTypes, request, RequestOptions, Rationale, check, Permissions } from '@nativescript-community/perms';
declare var global: any;

export const getPermissionTypes = () => {
    console.log(`Getting  permission types for the platform`)
    console.log(getTypes());
}

export const requestContactsPermission = (): Promise<any> => {
    let perm: Permissions = `contacts`;
    let rationale: Rationale = {
        title: global.AppName + ' contacts permission',
        message: global.AppName + ' needs access to your contacts.',
        buttonPositive: "OK", // optional
        //buttonNegative?: string;
        //buttonNeutral?: string;
    },
        opts: RequestOptions = {
            type: 'always',
            rationale
        };
    return request(perm, opts).then(response => {
        //this.setState({ locationPermission: response[0] })
        console.log(response)
    });
}

getPermissionTypes works fine but requestContactsPermission throws the error in title in the calling function.

I have the following permissions added to AndroidManifest.xml

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />

@sido420 you are using n7 version with N 6.x (share your package.json next time, easier to see all). Either use nativescript-perms with N 6.x or @nativesciprt-community/perms with N 7.x

Same error even with nativescript-perms

import { getTypes, request, RequestOptions, Rationale, check, Permissions } from 'nativescript-perms';

npx tns platform  clean android
npx tns build android
npx tns debug android

Can you share the full error stack?

[sido420]

Sorry for the late response.

I tried many things, but couldn't get NS to print a meaningful stack trace.

All of the following just give me the error in title:

• https://docs.nativescript.org/core-concepts/error-handling
• console.log(e)
• console.trace(e);
• console.error(e)
• throw e;
• console.dir(e) prints nothing

If you know of anything else that I can try, I'd be happy to do so. Other than that, plz let me know if theres any other way I could help you debug.

[farfromrefug]

It gave you the error but with more Please copy your full console log from when you get that error
