Ich habe zwei Fragmente, in denen beide dieser Fragmente, Codes ausgeführt werden, die sqlbrite verwenden. Während die App bei normalem Gebrauch nicht abstürzt, ist das Problem, wenn ich diese zwei Fragmente mehrmals hintereinander hin- und herlade, stürzt die App mit diesem Fehler ab.pthread_create fehlgeschlagen: 1064960-Byte-Stack konnte nicht zugeordnet werden: Nicht genügend Speicher

Eines der Fragmente hat etwa 50 Observable, die dann mit Observable.combineLatest kombiniert werden. Hier ist das Code-Snippet für das Fragment (das andere Fragment hat einen ähnlichen Code). Unten ist im Grunde die vereinfachte Version meines Codes.
public class MenuSummary extends Fragment{
private DbHelper dbHelper;
private Observable<?> incomeFromParentJar, getIncomeNecessities, getIncomeSavings, getIncomeEntertainment, getIncomeInvestment, getIncomeEducation, getIncomeCharity;
private Observable<?> getExpensesNecessities, getExpensesSavings, getExpensesEntertainment, getExpensesInvestment, getExpensesEducation, getExpensesCharity;
private Observable<?> getTotalUnpaidMonthlyRecurringExpensesNecessities, getTotalUnpaidMonthlyRecurringExpensesSavings;
private Observable imin;
private Subscription s;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
dbHelper = new DbHelper(getContext());
}
@Override
public void onPause(){
super.onPause();
dbHelper.close();
s.unsubscribe();
}
@Override
public void onResume(){
super.onResume();
displaySummary(selectedYear,selectedMonth);
}
@Override
public void onStop() {
super.onStop();
}
@Override
public void onActivityCreated(Bundle savedInstanceState){
super.onActivityCreated(savedInstanceState);
}
private void displaySummary(final int selectedYear, final int selectedMonth){
incomeFromParentJar = dbHelper.getParentJarIncomeUpTo(selectedYear,selectedMonth);
getIncomeNecessities = dbHelper.getIndividualJarIncomeUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_NECESSITIES);
getIncomeSavings = dbHelper.getIndividualJarIncomeUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_SAVINGS);
getIncomeEntertainment = dbHelper.getIndividualJarIncomeUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_ENTERTAINMENT);
getIncomeInvestment = dbHelper.getIndividualJarIncomeUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_INVESTMENT);
getIncomeEducation = dbHelper.getIndividualJarIncomeUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_EDUCATION);
getIncomeCharity = dbHelper.getIndividualJarIncomeUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_CHARITY);
getExpensesNecessities = dbHelper.getJarExpensesUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_NECESSITIES);
getExpensesSavings = dbHelper.getJarExpensesUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_SAVINGS);
getExpensesEntertainment = dbHelper.getJarExpensesUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_ENTERTAINMENT);
getExpensesInvestment = dbHelper.getJarExpensesUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_INVESTMENT);
getExpensesEducation = dbHelper.getJarExpensesUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_EDUCATION);
getExpensesCharity = dbHelper.getJarExpensesUpTo(selectedYear,selectedMonth,MySQLiteHelper.JAR_CHARITY);
List<Observable<?>> myObservables = Arrays.asList(incomeFromParentJar,getIncomeNecessities,getIncomeSavings,getIncomeEntertainment, getIncomeInvestment,getIncomeEducation,getIncomeCharity,getExpensesNecessities,getExpensesSavings,getExpensesEntertainment,getExpensesInvestment, getExpensesEducation,getExpensesCharity);
imin = Observable.combineLatest(myObservables, new FuncN<List<BigDecimal>>() {
@Override
public List<BigDecimal> call(Object... args) {
BigDecimal incomeTotal, incomeNecessities, incomeSavings, incomeEntertainment;
BigDecimal incomeInvestment, incomeEducation, incomeCharity;
List<BigDecimal> incomeFromParentJar = (List<BigDecimal>) args[0];
List<BigDecimal> expensesAndBalance = new ArrayList<BigDecimal>();
incomeTotal = incomeFromParentJar.get(0);
incomeNecessities = incomeFromParentJar.get(1);
incomeSavings = incomeFromParentJar.get(2);
incomeEntertainment = incomeFromParentJar.get(3);
incomeInvestment = incomeFromParentJar.get(4);
incomeEducation = incomeFromParentJar.get(5);
incomeCharity = incomeFromParentJar.get(6);
incomeNecessities = incomeNecessities.add((BigDecimal) args[1]);
.....
.....
.....
}
}
).subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread());
s = imin.subscribe(new Action1<List<BigDecimal>>() {
@Override
public void call(List<BigDecimal> expensesAndBalance) {
//do plenty of view.settext here
}});
}
Und so sieht die DbHelper-Klasse aus. Beachten Sie, dass ich nur den Code für eine der aufgerufenen Funktion anzeigen .. die andere Funktion ist ziemlich genau das gleiche (mit Ausnahme der Abfrage natürlich) ..
Kann jemand genau feststellen, wo ich falsch gelaufen bin?
public class DbHelper {
private MySQLiteHelper mySQLiteHelper;
SqlBrite sqlBrite = new SqlBrite.Builder().build();
BriteDatabase briteDb;
Subscription subscription;
private static DbHelper instance;
public DbHelper(Context context) {
mySQLiteHelper = new MySQLiteHelper(context);
sqlBrite = new SqlBrite.Builder().build();
}
public Observable<BigDecimal> getIndividualJarIncomeUpTo(final int endYear, final int endMonth, final int moneyJar){
briteDb = sqlBrite.wrapDatabaseHelper(mySQLiteHelper,Schedulers.io());
final String[] args = new String[]{moneyJar + "", endYear + "", endMonth + "", endYear + "", };
Observable<BigDecimal> myObservable;
myObservable = briteDb.createQuery(MySQLiteHelper.TABLE_INCOME, "SELECT total FROM " + MySQLiteHelper.TABLE_INCOME +
" WHERE moneyJar = ? AND ((year = ? AND month <= ?) OR (year < ?)) and isDeleted = 0", args)
.map(new Func1<SqlBrite.Query, BigDecimal>() {
@Override
public BigDecimal call(SqlBrite.Query query) {
Cursor cursor = query.run();
BigDecimal income, incomeTotal = new BigDecimal(0);
if (cursor != null) {
try {
if (cursor.getCount() > 0 && cursor.moveToFirst()) {
do {
income = new BigDecimal(cursor.getString(cursor.getColumnIndex("total")));
incomeTotal = incomeTotal.add(income);
} while (cursor.moveToNext());
}
} catch (Exception e) {
e.printStackTrace();
} finally {
cursor.close();
}
if (moneyJar == 1) {
Log.v(FILE_NAME, "imini " + endYear + " " + endMonth + " incomeTotal: " + incomeTotal);
}
}
return incomeTotal;
}
});
return myObservable;
}
public void close(){
if (briteDb != null) {
briteDb.close();
}
}
}
scheint wie ein allgemeines android Cursor/Speicherproblem, würde ich vorschlagen, um sicherzustellen, dass alle Cursor korrekt geschlossen sind, obwohl der Code scheint gut (vielleicht Abmeldung nicht mit Cursor rechts behandeln?), Sollten Sie versuchen, offene Cursor mit StrictMode zu verfolgen. Abgesehen davon, dass es sich um ein generelles Problem mit zu wenig Arbeitsspeicher handelt, versuchen Sie, die Prozessgröße zu ändern, um zu sehen, ob sie verwandt ist. – yosriz
@yosriz. Wenn ich den strikten Modus aktiviere, stürzt die App ab, wenn sich die Ausrichtung mit der Meldung ändert, dass einige offene Cursor nicht geschlossen sind. Und wie Sie sehen können, habe ich endlich cursor.close() hinzugefügt. Ich bin mir nicht sicher, ob ich eine andere Methode kenne, um die Cursor zu schließen. – imin
Nur um sicher zu sein, dass der cursor.close() erreicht ist, starte ich die App im Debug und bringe in allen cursor.close() brickpoints, und alle bremspoints sind erreicht. – imin
