parseacl | A cisco ACL parser | Authorization library

Apologies, I know there are similar questions on the forum already, but none of them seem to be quite the same issue as I'm running into here. I've just completed an Android tutorial course, and built and released my very first app - I'm a newbie so forgive me if I've done something stupid!

My app works fine on the laptop - on a variety of emulators, with a variety of SDK versions, and also works on a real device when plugged into the laptop with a USB cable. However, when I upload it onto the GooglePlay store (and wait 3 days for it to get reviewed!) it then doesn't work when I download it - onto the same device as was connected via USB.

The app crashes before the first page even opens, and the only error info I can get it the error info provided by GooglePlay - included below. The problem appears to be with my Parse Initialisation, but I don't know what or why? Any help would be much appreciated!

GOOGLEPLAY ERROR LOG:

I [followed the following guide to include][1] Parse Server in Android Studio

1. I downloaded the file PARSE-SDK-Android

2. Then I inserted maven { url "https://jitpack.io" }

in build.gradle(With my project name in brackets)

1. I inserted implementation "com.github.parse-community.Parse-SDK-Android:parse:1.25.0" in gradle.build module

2. The last code I entered, was this:

[Method OnCreate][2]

When I run this app, I always get an exception, cant upload this one object to my server. I couldnt insert the last step of the guide (Inserting android:name=".App" in AndroidManifest, because I get an error. Can someone help me? Thank you. And I dont know what to do with the SDK that I downloaded in the first step, because other than in the first step, it isnt mentioned anywhere else

EDIT: I upload the important areas of my code:

The app class:

I have trouble using my Parse Server that I created using Amazon Web Service.

I try to add a user through ParseUser in my MainActivity with a Button onClick method but it doesn't work for some reason... The error is : Error : com.parse.ParseRequest$ParseRequestException: i/o failure

It all worked well yesterday btw, but it was in Android Studio version 2.2.1. But today I want to try it on the updated version 3.4.1. I had to modify some lines in the Gradle files but nothing elsewhere so I don't know if it's relevant.

I don't know either what info you need to help me so I'm gonna put everything that might be implied... Sorry for the very long message

My MainActivity class:

I am trying to run the app that uses Anonymous login in the Parse server, but I get the Following in the log cat.

The app runs on only one of my device with android oreo 8.1, but when tried it on other device with Android pie the log cat gives the.

And this happens only with this app, other apps where I take the username and password from the user there also I get the same error.

I have tried all possible solution given to this problem on stackoverflow but the error doesn't goes.

Does anyone know is the Parse server which allows only one device to connect?

Manifest file

I'm getting a NullPointerException at an Attempt to invoke virtual method double android.location.Location.getLatitude() on a null object reference.

I'm using parse server (back4app.com). Spent hours trying to figure out the problem can anyone help.

Thank you in advance

I have reach a point in my app development where I wanted to test it on an actual device (rather than an emulator). Although the app isn't finished, it works perfectly as it should while running on the emulator.

So I built an APK to transfer to my device and install it. This has all gone well however, when I press a button that runs a ParseQuery to build an array, attach it to a ListView and display in an AlertDialog, all I receive (after a 30-45 seconds) is a toast programmed in as an error handler stating 'i/o failure' - this is the message retrieved from the ParseException.

Unsure about the internet permission requirements regarding ParseServers (it worked fine in the emulator without the internet permission), I tried adding the internet permission to the manifest and tried again... this produced the same result.

I have tried debug and release builds, as well as signed and unsigned APKs all with the same results. With the exception of an unsigned release build that my phone would not install.

I am at a loss with this as it's the first time I have tested an app using ParseServer so I ask all you fine folks if there is any assistance you can provide.

Let me know if there are any specific code segments you need to see and i'll post them but as I say, it works fine in the emulator so I can only assume it's potentially an issue with either the way I build the apk or in the deployment of the ParseServer instance on AWS.

oh.. and i have opted not to use any kind of user authentication with this app as yet so i don't access the user class in any way and automaticuser is enabled.

Code requested @Davi Macêdo - I'm not sure which part of the initialisation you are requesting so I'll add all areas I believe involve setting up Parse for this app -

.StarterApplication -

I have my Android app using the Parse server for backend service. A number of users are currently using my Android app. However, some particular users faced the problem at app installation that an object is not created in the Installation table even after log-in.

When I took a look at the problem from my Android app with some Analytics code, I found that ParseInstallation.getCurrentInstallation().getObjectId() returns null for the user even though Parse initialization process is completed properly. With the Analytics code, I checked the method every 10 seconds for 10 minutes after Parse initialization, but that method always returned null for the particular user.

TL;DR

Setting an ACL with a role permission fails sometimes because the role's name is interpreted as the permission type.

In a Cloud Code function, I create an ACL object and use setRoleReadAccess to grant read access to a role:

I have a function with a line that is supposedly meant to prevent a concurrent modification exception List parseObjectKeys = new ArrayList<>(parseObject.keySet()); However it still happens every now and again
