I have an app and I need it to access a code when the app is forced to close (force-Killed). Below I will leave the code for better understanding, however it is on onDestroy and does not run when the application is forced to close, just what I wanted!
However, I need the user to be able to get out and back in the app and only run the code when it actually closes it!
@Override
protected void onDestroy() {
//Ao fechar completamente a tela de validação com o campo textValidacao nulo ou incorreto, o cadastro no autenticacao e no banco de dados sao apagados, para evitar o cadastro de usuarios não validados.
String codigoDigitado = codigoValidacao.getText().toString(); //Pega o texto da caixa de texto8
if (! codigoDigitado.equals(tokenGerado)) {//Verifica se esse texto e igual, caso ele seja diferente do tokenGerado
user = UsuarioFirebase.getUsuarioAtual();//Pega usuario atual
user.delete().addOnCompleteListener(new OnCompleteListener<Void>() { //deleta o usuario no Auth
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {//Testa para ver se funcionou
Log.i("Usuario deletado(auth)","Sim");
}else{
Log.i("Usuario deletado(auth)","Não");
}
}
});
DatabaseReference firebaseRef = ConfiguracaoFirebase.getFirebase();//Excluir registro no realtime database
final String identificadorUsuarioLogado = Base64Custom.codificarBase64(UsuarioFirebase.getIdentificadorUsuario());//Id usuario
DatabaseReference usuarioExcluirRef = firebaseRef//Referencia do usuario
.child("usuarios")
.child(identificadorUsuarioLogado);
usuarioExcluirRef.removeValue();//Remove os valores
DatabaseReference testeOkRef = firebaseRef.child("usuarios");//Acessa o no usuarios
testeOkRef.addListenerForSingleValueEvent(new ValueEventListener() {//testa se o usuario foi deletado, vendo se ainda existe o identificadorUsuarioLogado no nó usuarios
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (dataSnapshot.hasChild(identificadorUsuarioLogado)){//Verifica sem tem o filho no nó
Log.i("Usuario deletado(Banco)","Não");
Toast.makeText(ValidadorActivity.this, "Usuario deletado(Banco) - Não", Toast.LENGTH_LONG).show();
}else {
Log.i("Usuario deletado(Banco)","Sim");
Toast.makeText(ValidadorActivity.this, "Usuario deletado(Banco) - Sim", Toast.LENGTH_LONG).show();
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
autenticacao.signOut();
Intent i = new Intent(ValidadorActivity.this, CadastroUsuarioActivity.class);
startActivity(i);
finish();
super.onDestroy();
}
Force-Killed is the same thing as
kill -9, is an order for the operating system to kill the running process. As far as I know it is instant and gives the process no opportunity to runonDestroy()or any code that is.– Piovezan
Yes, so you needed a q method to run when the Foce force-Killed app
– Luis Felipe
Read the documentation of
onDestroy(), I believe he gives no guarantee of being called. And no method will give this guarantee.– Piovezan
It is not called even, I look for a similar method, but q execute when force-Killed. I’ve been looking for a while
– Luis Felipe
I’m telling you, you’re not gonna find another method that guarantees that.
– Piovezan
I’ll try another way here, thank you!
