I have an Android application that constantly sends several data to my server, I need this data to be sent constantly throughout the day, however, sending the data takes about an hour and then the application closes and it shows me this error:
java.lang.OutOfMemoryError: Failed to allocate a 24 byte allocation with 0 free bytes and 3GB until OOM
I tried what they say in this post to add in the% android:hardwareAccelerated="false" and android:largeHeap="true" but the app is still closing me.
This is the part of the code where I process the strings that I receive by bluetooth and sent to my server to insert the data in my BD.
private Handler mMainHandler = new Handler()
{
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case CONST.MSG_LEER:
String readMessage = msg.obj.toString();
int charInicioCadena = readMessage.indexOf("#");
int charInicioTiempo = readMessage.indexOf("{");
int charInicioValor = readMessage.indexOf("(");
int charInicioValor2 = readMessage.indexOf(")");
int charFinCadena = readMessage.indexOf("~");//#lab{10000(~
if (charFinCadena > 0) {
try {
nombreDispositivo = readMessage.substring(charInicioCadena + 1, charInicioTiempo);
switch (nombreDispositivo) {
case "ecg":
cuenta++;
segundo = readMessage.substring(charInicioTiempo + 1, charInicioValor);
valorECG = readMessage.substring(charInicioValor + 1, charFinCadena);//Valor ECG de tipo cadena
ecgValuefloat = Float.parseFloat(valorECG);
//checar minimo y maximo cada entrada
if(ecgValuefloat<Globals.valorMinimo){Globals.valorMinimo=ecgValuefloat;}
if(ecgValuefloat>Globals.valorMaximo) {Globals.valorMaximo=ecgValuefloat;}
if(Globals.envio_permitido==1) {
Globals.lstPromedios.add(ecgValuefloat);
Globals.lstTiempoPromedio.add(Integer.parseInt(segundo));
Globals.lstSendContadorECG.add(cuenta);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
ServiceManager2.onSendData();
}
},257);//Tiempo de retardo para empezar a enviar datos.
}
MainActivity.mECGWaveDraw.add(Integer.parseInt(valorECG));
break;
