I also gone through the file “CurrentUserRepo” → getCurrentUser function.
public static CurrentUser getCurrentUser() {
CurrentUser user = null;
try {
SQLiteDatabase db = SQLiteManager.getInstance().openDatabase();
Cursor cursor = db.rawQuery("SELECT * FROM CurrentUser WHERE uid LIKE '" + PreferenceHelper.getLoggedInUID() + "'", (String[])null);
if (cursor != null && cursor.moveToFirst()) {
cursor.moveToFirst();
user = new CurrentUser();
user.setUid(cursor.getString(0));
user.setName(cursor.getString(1));
user.setAvatar(cursor.getString(3));
user.setLink(cursor.getString(4));
user.setRole(cursor.getString(5));
if (cursor.getString(6) != null) {
user.setMetadata(new JSONObject(cursor.getString(6)));
}
user.setStatus(cursor.getString(8));
user.setStatusMessage(cursor.getString(9));
user.setLastActiveAt(cursor.getLong(10));
user.setIdentity(cursor.getString(11));
user.setSecret(cursor.getString(12));
user.setAuthToken(cursor.getString(13));
user.setJwt(cursor.getString(14));
String tagsArray = cursor.getString(15);
if (tagsArray != null) {
JSONArray tags = new JSONArray(tagsArray);
List<String> tagsList = new ArrayList();
for(int i = 0; i < tags.length(); ++i) {
tagsList.add(tags.getString(i));
}
user.setTags(tagsList);
}
}
SQLiteManager.getInstance().closeDatabase();
} catch (JSONException var7) {
Logger.error("Error getting users from local database : " + var7.getMessage());
}
return user;
}
Here the cursor used is not closed anywhere and is being called multiple times.
I debugged the code placing the breakpoint on getCurrentUser() which is being called 30-40 times in debug build and is continuously called in some intervals.
