How to add the dependency in android studio?

Hi ..

Great work..

I would like to know how to add the dependency and fix the following issues-...

Thanks a lot

Two Different Application issues

The App which is there in Google App store i.e. ESP32 OTA BLE is different and the source code you have given in the repo is different and this one is getting crash. The one which is available in google play store is working correctly so can you provide me the repository of that..

Installation error with Android 12: INSTALL_PARSE_FAILED_MANIFEST_MALFORMED

There seems to be an Manifest issue since Android 12.

I could run the App on Android 9 and Android 11 without any issues.

The PlayStore Version seems to run on Android 12 as well.
Launching 'app' on samsung SM-G970F. Installation did not succeed. The application could not be installed: INSTALL_PARSE_FAILED_MANIFEST_MALFORMED
(I tried other Android 12 Devices as well)

Flutter Ble

I am making flutter app. I am facing problem in sending file to esp32 can you tell me steps needed before sending file

app not connecting

I can't get the android app to connect.
I've tested on phones is running Android 8 and Android 11 with same (failed) results

I've built and installed the android app using android studio and it uploads/run on both devices without any reported errors.
I tried initially without linking any additional libraries since another closed issue implied this is no longer required. Because this failed I tried linking to fbiego/Android_BLE_Library, but this states the module already exists (not a suprise and your readme.md needs to be updated to reflect that this isn't required any more). I also tried to linked to a clone of https://github.com/NordicSemiconductor/Android-BLE-Library but this doesn't do anything either (although I didn't change any code for this attempt).

In another issue you've stated you've essentially cloned https://github.com/NordicSemiconductor/Android-BLE-Library
However the readme for this specifically states
"The library does not provide support for scanning for Bluetooth LE devices. For scanning, we recommend using Android Scanner Compat Library which brings almost all recent features, introduced in Lollipop and later, to the older platforms."
and recommends using https://github.com/NordicSemiconductor/Android-Scanner-Compat-Library
I did trying linking this repo but it doesn't help either (although again without any changes to code).

Incidentally the arduino sketch doesn't appear to be the issue:
I've installed the nimBLE arduino sketch - that's working fine. The same is true if I use the ESP32 OTA ardunio sketch.
Both correctly connect to the "nRF Connect" android app and report the GATT Service Generic Access and Generic Attributes as well as the custom device SERVICE_UUID = fb1e...
If I put Serial.prints in the sketches the ESP32 is appropriately reporting a connection with nRF.

Android BLE Library Version?

Hello! First of all, I think this ESP32 BLE OTA updater is very awesome and I want to incorporate something similar into one of my ESP32 projects.

I am attempting to debug this project in Android Studio in an attempt to understand the code a bit better, but am running into the issue of not having the Android BLE library in the source folder of the application. I added the latest version of this library as a dependency with the line below

implementation 'no.nordicsemi.android:ble:2.3.1'

in my build.gradle file, but am still facing compiling errors (potentially due to a library version change, I'm thinking).

Would it be possible to include the library source code in the repository or inform me of the version you were using when this application was written?

Any help or suggestions will be much appreciated... Thanks in advance!
