    Android Dev - Help .. Lost password for signing app

    Help .. Lost password for signing app

    Posted: 24 Jan 2021 03:44 AM PST

    Hello, I just took over an app which was built by a contractor and was released by him. Now I am trying to release an update. I got the Keystore file from him. But he doesnt remember the password. So not able to sign the new release of the app and upload to Play store. Anyway to solve this? I came across this form for requesting Google to reset the key https://support.google.com/googleplay/android-developer/contact/key

    But there is an option which says that "Upload key misplaced". I just wanted to understand that the signing key and upload keys are different?

    Please help

    Is it still lucrative to build android apps in 2021 on your own?

    Posted: 23 Jan 2021 12:22 PM PST

    As a single developer, how hard is it nowadays to build a successful app on your own, without having a team? Cause there are so many crazy apps for like everything. What is your opinion?

    Python -.py to APK?

    Posted: 24 Jan 2021 07:37 AM PST

    So I'm new to python and i got into a really interesting project all python based

    I'm using old phones as sensors and wifi extenders and more other stuff

    all working with a python script i wrote the first phone acts as a sensor and it sends a true or false value to the other phone through a telegram bot

    if the value is true it will make a wifi bridge connection to extend my wifi it will be useful if your router doesn't cover the whole home

    anyway my project is done and it's all working good but i want to export it as apk and have all the processes automated

    Right now I'm running scripts on termux with python3.8 installed and adb

    let's say i want share this project with a friend of mine he have to install termux and install python on it then install dependings from pip then setup adb to connect from local host then run the script.

    MY question is : Is it possible to maybe compile the .py file to apk and run it directly? Like on windows you can compile .py files to exe and run it without python installed is that possible on Android?

    Hello! I recently learned that you could make your own version of the Android OS. I wanted to know what coding language it uses and how to get the source code.

    How to fix the error: null is not an object (evaluation of 'bleManager.start')?

    Posted: 24 Jan 2021 07:12 AM PST

    I use the react-native-ble-manager library to connect an Android smartphone to a BLE device. But when calling the BleManager.start() , an error immediately occurred, I already looked at Issues on GitHub, the solutions that are there did not help me in solving this problem. My steps in installing lib:

    1. npm i --save react-native-ble-manager
    2. ​

    ​

    // file: android/app/src/main/AndroidManifest.xml ... <uses-permission android:name="android.permission.BLUETOOTH"/> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> ...

    I've tried using ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION, both together and separately.

    1. npm i

    2. In README.md it is written that there is support autolink, but it will not be superfluous: react-native link && react-native link react-native-ble-manager

    ​

    I don't use Expo. When running the example from the library, the same error occurs. I use only this in my project (not example):

    ... import BleManager from 'react-native-ble-manager'; ... const scanAndConnect = () => { BleManager.start() .catch((err) => { console.error(err); }); }; ...

    build.gradle info:

    buildToolsVersion = "29.0.2" minSdkVersion = 16 compileSdkVersion = 29 targetSdkVersion = 29

    OS: Android 9.0

    For a social heavy app, React Native or Ionic with Cordova or Capacitor (or not…)?

    Posted: 24 Jan 2021 03:06 AM PST

    Hello guys. I'm starting a project that will be very reliant on social interactions. Having already published a few Ionic apps, and always struggled with all that's social login, sharing etc… I was wondering what do you think about it nowadays?

    My app will need as much as possible social logins, sharing, and friends import.

    So, do you think an hybrid Ionic app is still a good fit for something like this? Is React Native better on that aspect? Or do I have no choice but to go native...

    Thanks ahead!

    Using LiveData with TextView

    Posted: 24 Jan 2021 01:00 AM PST

    Hi peeps, not sure if this is something allowed, if not then remove it...

    I'm using Android Room (to which I'm very new to) and I'm trying to use the following:

    @Query("SELECT COUNT(*) FROM table_projects") LiveData<Integer> getDatabaseCount();

    I'm also using a TextView to initially display 0 and I then want it to show the database size.

    However, I'm unsure how I actually use LiveData. When I try to use getDatabaseCount().getValue() it returns null which is expected.

    I've seen online that I need to use a ViewModel to observe the LiveData and then update the TextView once it's been updated, however, I cannot for the life of me find out how this is done.

    Once I understand how to use it with a TextView, I can apply it to other things in my app but I'm really struggling

    Cheers guys

    Creating First Android App

    Posted: 23 Jan 2021 12:53 PM PST

    Hi, I'm taking a senior level course where I have to build an Android mobile application. I've never actually done this before so I'm currently learning online on how to build mobile applications.

    That being said, does anybody have any recommendations for what I should build for my course (I have the choice). It's probably going to be around 3 months worth of developing and I want to be able to put this mobile application onto my resume.

    Thanks in advanced for your input!

    How do you do ASO?

    Posted: 23 Jan 2021 12:18 PM PST

    So, in web dev you have SEO and can use tools like Google Keyword Planner to find out how good keywords can be ranked and how big search volume is and etc....

    I had a hard time finding an easy, cheap tool to do the same for Android Google Play Store. There are several tools like AppAnnie, AppRadar and AppFollow. They cost around 70$ a month and a tried their free options. They all sucked and I didnt even know how to use their tool.

    So - how do you guys know if an app idea is worth it? How do you know if that app you are building is going to be searched for?

    Any help would be appreciated :)

    Is there a way to move files in Android storage access framework without rewriting entirely?

    Posted: 23 Jan 2021 09:34 AM PST

    Usually, moving files within the same volume works like renaming, which is instantaneous.

    But with Amaze file manager using Android storage access framework (used since Android 5.0 for third-party MicroSD access), the files are rewritten entirely, which is a waste of resources.

    Is that the fault of the file manager or storage access framework?

    Is Anyone an Android Dev in the Bay Area?

    Posted: 23 Jan 2021 07:34 PM PST

    Long story short, I'm an international student starting my third year doing CS in the Bay Area, I chose Android a few months back to dive deeper because I felt I was too general on many topics, but I really need to be really strong in one specific thing in order to get a high paying job (and be competitive when I start applying for jobs).

    I'm learning the core concepts with Native Android at the moment, and I'll try to stick with it until I graduate to get a Junior Dev job.

    I probably won't be coding my whole life(although I love anything related to tech and I like coding), and I only came to U.S. to make money in order to invest in other stuff back at my country, don't want to live here for too long.

    The question is, is there still a lot of Android Dev jobs around the Bay Area (is it competitive?) because I know for sure it pays very well on top companies(one of my main goal is to get a job at one of these, I had an interview with Google for an internship a few weeks ago, although I bombed because I only had 2 weeks to leetcode(I had to refresh a lot of stuff on data structures first)).

    But my main plan is to get this "dream" job, get passive income and invest back at my own business after a couple of years working here.

    Did I make a reasonable choice?

    Android Studio 4.1.2 CPU Profiler made my AS not responding, what to do?

    Posted: 23 Jan 2021 10:25 AM PST

    I just tested CPU Profiler with Trace Java Method configuration for two minutes on MacBook Pro 2019. Now is my Android Studio 4.1.2 not responding to any mouse click or key input. It did tell me the record was large and AS may not respond.

    What is the safe way to end this? Wait or kill the AS process? Any hint is welcome.
