can't register broadcast receiver in processing 3 ?

pauline909

Hi.

a simple code to check the battery state worked in processing 2.

it doesn't work anymore in processing 3

(my issue is I can't reinstall android mode in processing 2, the android mode doesn't appear in mode manager).

is this a known bug ?

here's the code:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;

int level=0;
int charging;
int voltage;
import android.os.BatteryManager;
int temp;
String tech;
void setup()
{
  battery_checking();
}
void draw()
{

}


void battery_checking()
{
  println("======================");
  println("Niveau Batterie :"+level+"% ");
  //  println("Technologie : "+tech);
  //  println("Voltage : "+voltage);
  //  println("Temperature : "+temp);
  //  println("plugged : "+charging);
  println("======================");
}


private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() {

  @ Override
    public void onReceive(Context c, Intent i) {


    level = i.getIntExtra("level", 0);
    voltage =  i.getIntExtra("voltage", 0);
    charging = i.getIntExtra("plugged", 0);
    tech = i.getStringExtra("technology");
    temp =  i.getIntExtra("temperature", 0);
  }
};

@ Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  registerReceiver(mBatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
}

thanks in advance !

it doesn't work anymore in processing 3

In what way doesn't it work? Does it print errors? Does it just not return a value?

Android version?

I try with android 7.1 and 6. processing gives me: "the function registerReceiver(BroadcastReceiver, IntentFilter)" doesn't exist...

@pauline909=== 2== you are in an Activity; 3== you are in a fragment; i think this is your problem (not tested!!!, guessed!!!) i verify Asap

I made some changes to your code. Check them out,

Kf

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;

import android.os.BatteryManager;
import android.os.Looper;
import android.app.Activity;
import android.app.Fragment;


Activity act;
Context mc;

int level=0;
int charging;
int voltage;
int temp;
String tech;


void setup()
{
  fullScreen();
  battery_checking();
  textSize(28);
  textAlign(CENTER,CENTER);
  fill(225);
}

void draw()
{
  background(25,25,220);
  text("Battery level: " +level+
  "%\nVoltage "+voltage+
  "\nCharging "+charging+
  "\nTechnology "+tech+
  "\nTemperature "+temp,
  width/2,height/2);
}

void battery_checking()
{
  println("======================");
  println("Niveau Batterie :"+level+"% ");
  //  println("Technologie : "+tech);
  //  println("Voltage : "+voltage);
  //  println("Temperature : "+temp);
  //  println("plugged : "+charging);
  println("======================");
}
private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() {

  @ Override
    public void onReceive(Context c, Intent i) {


    level = i.getIntExtra("level", 0);
    voltage =  i.getIntExtra("voltage", 0);
    charging = i.getIntExtra("plugged", 0);
    tech = i.getStringExtra("technology");
    temp =  i.getIntExtra("temperature", 0);
  }
};

@ Override
  public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  act = getActivity();
  mc = act.getApplicationContext();
  mc.registerReceiver(mBatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
}

@pauline909=== what kfrager added (lines 70_72) is the way to write code in a fragment...
