Stopped Service is Doing Constant Garbage Collection

Question

I am developing an application which has many services. When I stop the intent service, all threads and service should be stopped but the UI is hung and the following errors

Answer 1

Same problem also occured for me. But I am using SqLite. When I want to select List of my entity I forgot to add some important methods. When problem occured my code is following

 public List getBlockeds() {
    List blockeds = new ArrayList<>();
    String[] allColumns = {"id", "phoneNumber"};
    Cursor cursor = database.query("Blockeds", allColumns, null, null, null, null, "id desc");
    cursor.moveToFirst();
    while (!cursor.isAfterLast()) {
        Blocked blocked = new CursorToPojo().cursorToBlocked(cursor);
        blockeds.add(blocked);
    }
    return blockeds;
}

When change code to following the problem solved.

public List getBlockeds() {
    List blockeds = new ArrayList<>();
    String[] allColumns = {"id", "phoneNumber"};
    Cursor cursor = database.query("Blockeds", allColumns, null, null, null, null, "id desc");
    cursor.moveToFirst();
    while (!cursor.isAfterLast()) {
        Blocked blocked = new CursorToPojo().cursorToBlocked(cursor);
        blockeds.add(blocked);
        cursor.moveToNext();
    }
    cursor.close();
    return blockeds;
}

I realised that when I did not use cursor.moveToNext cursor never end and the preceding problem start.
