本文介绍了pthread_create失败:无法分配1064960字节的堆栈:内存不足的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有两个片段，在这两个片段中，它将执行利用sqlbrite的代码.虽然该应用程序在正常使用情况下不会崩溃，但是问题是，如果我在短时间内多次来回加载这两个片段，该应用程序将因该错误而崩溃.
I have two fragments where inside both of these fragments, it will execute codes that utilize sqlbrite. While the app won't crash in normal usage, but the problem is, if I load these 2 fragments back-and-forth multiple times in a short period, the app will crash with this error.

其中一个片段大约有50个可观察的片段，然后使用Observable.combineLatest将其合并.这是该片段的代码片段(另一个片段具有类似的代码).下面基本上是我的代码的简化版本.
One of the fragment has about 50 Observable which are then combined using Observable.combineLatest. Here's the code snippet for the fragment (the other fragment have a similar code). Below is basically the simplified version of my code.
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
}});
}
这是DbHelper类的外观.请注意，我只显示其中一个调用函数的代码..其他函数几乎相同(当然，除了查询)..
And here's how the DbHelper class looks like. Take note that I only display the code for one of the called function.. the other function is pretty much the same (except for the query of course)..
谁能指出我哪里出了错?
Can anyone pinpoint where did I went wrong?
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();
}
}
}
推荐答案
我重组了代码和sql查询，并将可观察对象的数量减少到只有12个，而不是原来的60个，问题消失了.因此，基本上，这个问题是由我方面的错误设计引起的.
I restructured my codes and sql query and lessen the number of observables to only 12 instead of the original 60, and the problem is gone. So basically this issue was caused by bad design on my part.
