Help! I don't get it! Storage is almost full and some apps may not work

Your profile indicates you have a Moto E5 Cruise from Cricket. If that's still current info, Motorola (Lenovo) has the user manual for your model posted online:
https://download.lenovo.com/Motorol...MotoE5Cruise.Cricket.UG.en-US.SSC8C29410A.pdf
It's kind of dry reading but thorough and covers the basic functionality of your particular phone.
If you're more of hands-on, tactile learner, look into if any local library or community college has any 'smartphone basics' classes. Note these tend to be very generic since there are so many variations involving the user interface for every model of phone, plus two very different platforms (Android and Apple). But if you are able to get at least some one-on-one tutoring, and use that combined with the user manual that does pertain to your particular phone, that's a good way to start learning what your phone can do for you.

Just for posterity, here's a link for the hardware specs for that model:
https://www.gsmarena.com/motorola_moto_e5_cruise-9575.php

Of course if you have a different phone model, it would really help if you provided just which one you do have and which version of Android its currently running. Documentation and tutorials for most Android devices have to be specific, and short-lived, as there's a lot (stress that) of variables involved with the user interfaces in each phone model.

Spyware? Over 20 system apps same storage size

If you didn't have any operating system processes running in the background, your phone would just be a completely inert, unusable object.
But to answer your question, yes it is very normal for things in your screen capture pics to be actively running in the background. They're part of what makes your smartphone do the things it can.

Playing different sounds on different buttons click

Hi guys,

I am new to android and I want to make a simple app for learning purposes.
So the app should be like this: if I press Button1, it will sing the sound1. If I press Button 2 the sound1 stops and plays sound2.
Here is what I made so far, but it doesn't work. I tried to search on different websites, but I didn't find anything that could help me so I thought it would be helpful a forum.
Any help please? :D

Thank you!

Java:
package com.example.moan;

import androidx.appcompat.app.AppCompatActivity;

import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    MediaPlayer cricket;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        Button btnCricket = (Button) this.findViewById(R.id.button);
        btnCricket.setOnClickListener(this);

        Button btnCricket2 = (Button) this.findViewById(R.id.button2);
        btnCricket2.setOnClickListener(this);




    }

    @Override
    public void onClick(View v) {
        switch(v.getId())  {
            case R.id.button:
                closeCricket();
                cricket = MediaPlayer.create(this, R.raw.manea1);
                break;
            case R.id.button2:
                closeCricket();
                cricket = MediaPlayer.create(this, R.raw.manea2);
                break;
            default:
                return;
        }


        cricket.start();


    }

    public void closeCricket() {
        if (cricket.isPlaying()) {
            cricket.pause();
            cricket.reset();
            cricket.release();
        } else {
            cricket.reset();
            cricket.release();
        }

Converting Blob to String in Android Room

I'm having trouble finding information on how to resolve an issue with reading file BLOB data with Android Room.

The Problem:
In the database there are 11 tables and one table called Files handles file attachments. There are 3 fields, FileID, Filename, FileData. FileData is the BLOB or byte data stored to build the file. The file can be anything, a picture, text file, Word, Excel, just about anything.

What I've tried:
I can't seem to find, if it exists, how I would setup my entity class to manage this field data. I searched on stackoverflow and developer.android.com but haven't discovered anything helpful yet. I did see that there is a method called getBlob() (https://developer.android.com/reference/android/database/Cursor.html#getBlob(int)) but this is related to the Cursor method, which Android Room handles all the Cursors.

I'm not sure where to go from here, so I was hoping someone may have had the same issue or knew how you would setup your Room code (e.g. Entities, etc) to manage this file data.

[Game][Free] Accumulate Ball

Hey,

An original arcade puzzle game Accumulate Ball for Android has been developed by our studio. You are welcome to test (comment): https://play.google.com/store/apps/details?id=com.eidnGames.AccumulateBall&hl=en.

1. Promo video
Gameplay is simple and contains the next parts:

1.1) Moving the ball through platforms to find a path to a reservoir with a substance of the specific color.

1.2) Filling the ball with the reached substance.

1.3) Repeating the steps 1.11.2 until the ball won't be completely filled.

2) Restoring the ball to a state before the step 1.1 and continuing the steps 1.11.3.

2.3. Smartphone screenshot
Game process is complicated by the following features:

1) It is necessary to find a path to a reservoir until the timer is stopped.

2) The ball orientation can be changed by rotators located at random platforms.

Application runs fast on smartphone but slow on tablet

Hello,
My team and I have developped an augmented reality application that uses native c++ libraries, it works well on multiple smartphones (xiaomi, samsumng, huawei, custom industrial android phones), but when it comes to tablet, the activity that contains the frames acquisition and manipulation runs slow.

We have tried on multiple table, the specs of the first ones weren't that great (under 2Gb ram, 4 cores below 1.7ghz and armeabi-v7a), but then we bought a tablet that has the same, or even better specs than the previously tested smartphones ( Lenovo M10+, with 4Gb ram, Octo core 2.3Ghz, armeabi-v8a), but the speed issue remains.

The code uses some shared libraries compiled for the specific architectures (opencv, ceres-solver), and the optimisation is set in the manifest.
FYI, android developpement isn't our strong suit.
Do you have any idea to why an app can be fast on smartphones but not on tablet ?

Thanks in advance.
