Reason for Not Enough ROM error!:

There are several reasons for this. Also, there are solutions to them. Sometimes, little precaution will help reduce your time consumption for a project. Otherwise, it may take hours, days, weeks even months to find the problem and solve it. Let’s find the reason and ways to solve that.

1. Using too much ASCII values

Convert the ASCII into a constant value. And print each digit one by one. Let’s see!

void Lcd_COut(char row, char col, const char *cptr)

package me.chayan.mediaplayerdemo;

import android.content.Context;
import android.content.res.AssetFileDescriptor;
import android.content.res.Resources;
import android.media.AudioFormat;
import android.media.AudioManager;
import android.media.AudioTrack;
import android.media.MediaPlayer;

It is a library that receives and returns the version of the application uploaded to the market. If it is different from the current version, you can write the code so that it can be updated after moving to the market.

We refine some methods on the Internet and distribute them in the form of a library. The original java source is also attached.

Be careful

How to parse and fetch the Google Market website It takes a lot of data

Download the BIOS update from Acer site ZQ0_125.exe
Run the downloaded file, you will get an error like No battery or Low battery, Don't close the error dialogue (!)
Navigate to your current users temp directory (e.g. Users//AppData/Local/Temp), there should be somewhere a temporary directory containing the extracted files from the EXE file (for me it was 7zS8C43.tmp)
Copy the temp directory somewhere (then you can then close the error dialogue, the temp files will be removed)
Open the file platform.ini with a text editor and search for the key AC_Adapter
Change parameter BatteryCheck from 1 to 0 or just leave it empty (this disables battery check during BIOS update preparation!), save the file
Run InsydeFlash.exe in the same directory

It solved my issue and work beautifully..

You can download this file from the browser or from the console. The latter is shown below (note: the specific Node.js version might be different for you):

wget http://nodejs.org/dist/v14.15.0/node-v14.15.0-linux-x64.tar.gz

sudo tar -C /usr/local --strip-components 1 -xzf node-v14.15.0-linux-x64.tar.gz

You may find list of node version on http://nodejs.org/dist/
