I have an app that updates the progress bar, the same way I’m doing in another app, but in this new app, the onProgressUpdate() only executes at the end of doInBackground().
It is called the method parseInsertSolicitantes(jsonString), where in the record insertion loop, it has the publishProgress(count).
Class Sincronizar
public class Sincronizar extends AppCompatActivity {
ProgressBar pb;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sincronizar);
this.pb = findViewById(R.id.progressBarSync);
}
private void syncCadastros() {
AsyncCadastros asyncCadastros = new AsyncCadastros(this, this.pb);
String retorno = "";
try {
asyncCadastros.execute();
retorno = asyncCadastros.get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
Log.i("lgg", "retorno sync cad: " + retorno);
}
}
Class AsyncCadastros
public class AsyncCadastros extends AsyncTask<String, Integer, String> {
Context ctx;
ProgressBar pb;
ConnectivityManager conexao;
public AsyncCadastros(Context ctx, ProgressBar pb) {
this.ctx = ctx;
this.pb = pb;
}
@Override
protected void onPreExecute() {
super.onPreExecute();
Log.i("lgg", "onPreExecute");
this.pb.setProgress(0);
this.pb.setVisibility(View.VISIBLE);
}
@Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
Log.i("lgg", "onPostExecute");
this.progressBar.setVisibility(View.GONE);
}
@Override
protected void onProgressUpdate(Integer... values) {
super.onProgressUpdate(values);
Log.i("lgg", "onProgressUpdate: " + values[0]);
this.pb.setProgress(values[0]);
}
@Override
protected String doInBackground(String... params) {
if (!verificaConexao(this.ctx)) {
return "Sem conexão";
} else {
...
String retorno = json;
if (retorno.equals("X")) {
return "X";
} else {
reader.close();
streamReader.close();
String jsonString = retorno.toString();
parseInsertSolicitantes(jsonString);
return null;
}
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (ProtocolException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
}
private boolean verificaConexao(Context ctx) {

}
private String parseInsertSolicitantes(String json) {
String jsonString = json;
JSONObject jsonObject;
JSONArray jsonArray;
int handle;
String nome;
DBController dbc = new DBController(ctx);
try {

int count = 0;
int regs = jsonArray.length();
this.pb.setMax(regs);
Log.i("lgg", "registros: " + regs);

dbc.atualizarSolicitantes(handle, nome);
Log.i("lgg", "Sync: " + count);
count++;
publishProgress(count);
}
return "parseInsertSolicitantes OK";
} catch (JSONException e) {
e.printStackTrace();
return "parseInsertSolicitantes ERRO";
}
}
}

You must call
onProgressUpdatewithin thedoInBackground– Valdeir Psr
I didn’t know there was such a thing. But I wanted to do like the other, which is pretty much the same thing. I asked the question about the code of what is working.
– rbz
The other calls the method
publishProgressinsidesync(String json), which in turn is called by thedoInBackground. That is, it is necessary to callonProgressUpdatefrom the methoddoInBackground– Valdeir Psr
The content of the method
syncwas inside thedoInBackground, I just took it out to test, as I did in the new App. And it worked both ways. I’m not yet understanding why of putting one inside the other...– rbz
Even, the 2 call methods. The only difference is the
voidandStringin them.– rbz
You don’t mean the
publishProgressinstead ofonProgressUpdatenay ?– rbz
Friend, looking closely your code seems to be all running, you say call the progressiUpdate at the end to update your progressionBar, but you have already put a log on inside the onProgressUpdate? Because I think everything is running so fast that the update is almost instantaneous.
– Weslley Barbosa
@Weslleybarbosa yes, the log is inside each part, is the "Example of output"... is not speed, because in the other app is faster still, including I limit to 5, 10, results for the test, because it has thousands. I haven’t taken to see it again yet, but it’s a mystery !
