OutOfMemoryError OutOfMemoryError 인출

Question

내 시나리오은 데이터베이스에 데이터가 있습니다 SQLite입니다. 내가 얻을 수있는 데이터의 올바르게, 나는 가지고 여기

Cursor c0 = OCTDBHelper.myDataBase.rawQuery("SELECT DISTINCT ALIAS FROM ICT32 where ALIAS NOT NULL", null); 
Log.i("IC-Count", "IC-Count : " + c0.getCount()); 
String arr[] =new String[c0.getCount()]; 

    c0.moveToFirst(); 
     for(int i = 0; i < c0.getCount(); i++) 
     { 
      arr[i] = c0.getString(0); 
      c0.moveToNext(); 

     } 

모든 데이터의 정확히 같은 arr에서,

편곡 [0] : ABCB, hjhj, jkshdf, hdjf, ghsg, aghgh,

arr [1] : klkl, sdjk, jkji, iui, jiji, jij,

. . .

도착 [N] : QW, RWER 재, TR, yty, UYU, RTR, TER, ETR, YRT는 YTR

ie, 각 위치와 comma(,) 10-30 데이터를 갖는다. 배열 n'th 위치에 도달 할 때까지 내가 comma(,)에 따라 split(",") 필요하고 단일 List에 추가

• 로 다음과 같은 total arr.length is 1322

  해당 데이터를 얻기 후에 나는 그 데이터로 어떤 작업을 할 필요가있다.

• 결국 내 출력

  목록되어야 [0] hjhj

  리스트 [2] [1]

  리스트 ABCB jkshdf

  ...

  목록 [n-1] : yrt

  목록 [N] : YTR

는 이미 제대로했다고 생각. 하지만

Cursor c0 = OCTDBHelper.myDataBase.rawQuery("SELECT DISTINCT ALIAS FROM ICT32 where ALIAS NOT NULL", null); 

Log.i("IC-Count", "IC-Count : " + c0.getCount()); 
ArrayList<String> tmp = new ArrayList<>(); 
c0.moveToFirst(); 
     for(int i = 0; i < c0.getCount(); i++) 
      { 
       String arr[] = c0.getString(0).split(","); 
        for(int j= 0; j< arr.length;i++) 
          { 
           if(!arr[j].equals(",")) 
            { 
             tmp.add(arr[j]); 
            } 
          } 
        c0.moveToNext(); 

      } 

Log.i("Alias" , "count : " +tmp.size()); 

이 코드를 제공, Throwing OutOfMemoryError

내 코드는 같은 오류를 제공 Throwing OutOfMemoryError

Answer 1

이 :

for(int j= 0; j< arr.length;i++) 

변경 j++에 i++이 버그를 수정합니다.
