SharedPreferences会在使用前不断删除

这是斗士。我将int值存储在共享的pref中,本质上将它们缓存,以便下次启动时可以将它们放入数据库中。我有一种在启动时将它们保存到数据库的方法。
这后面是从共享的首选项中删除值以重置它们的方法。
但是在我将它们存储到数据库之前,它们似乎一直在删除。无论我做什么,它都像deleteMetrics();
在setMetrics();
之前运行。
- 我尝试将删除共享的pref值放在自己的位置启动活动中的方法。
- 我已尝试将启动时setMetrics方法中的共享首选项值活动。
- 我已尝试删除共享的pref值在启动活动的onCreate中的不同位置。
- 我尝试将删除的共享pref值放入
Metrics
内部和外部的startupUpdateMetrics()
类方法。 - 我曾尝试将共享的pref值删除如果线程泄漏(请参见下文),请输入
runOnUiThread
。 - 我已经在onCreate中尝试在
settMetrics();
和deleteMetrics();
之间进行启动活动的Thread.sleep(5000)>
没有任何作用。在setMetrics();
方法将值存储到DB之前,这些值将被删除。
如果我注释掉deleteMetrics();
,DB值会很好地存储,但是它们会成倍增加,因为没有为每种应用使用而重置sharedPrefs。
在onCreate上启动活动:
Activity_Splash.this.runOnUiThread(new Runnable() @Override public void run() setMetrics(); deleteMetrics(); );
setMetrics();和deleteMetrics();
private void setMetrics() SharedPreferences sharedPreferences = Activity_Splash.this.getSharedPreferences("com.dmurphy.remotescrumpoker", Context.MODE_PRIVATE); //Check if device has a network connection boolean connectionExists = new NetworkConnection().haveNetworkConnection(passedActivity, TAG); //If device has a network connection continue if (connectionExists) Log.i(" => ", "Test1"); try String userId = mAuth.getCurrentUser().getUid(); int teamCreated2 = sharedPreferences.getInt("teamCreatedForMetrics", 0); Log.i(" => ", "Test2 " + teamCreated2); callMetrics.startupUpdateMetrics(userId, context); catch (Exception e) Log.e(TAG + "onCreate", "Error setting metrics"); private void deleteMetrics() SharedPreferences sharedPreferences = Activity_Splash.this.getSharedPreferences("com.dmurphy.remotescrumpoker", Context.MODE_PRIVATE); try sharedPreferences.edit().remove("acceptedForMetrics").commit(); sharedPreferences.edit().remove("rejectedForMetrics").commit(); sharedPreferences.edit().remove("requestedForMetrics").commit(); sharedPreferences.edit().remove("sm2AppointedForMetrics").commit(); sharedPreferences.edit().remove("teamCreatedForMetrics").commit(); sharedPreferences.edit().remove("teamDeletedForMetrics").commit(); sharedPreferences.edit().remove("noOfPlayersForMetrics").commit(); sharedPreferences.edit().remove("teamsMemberLeaveForMetrics").commit(); catch (Exception e) Log.e(TAG + "onCreate", "Error setting metrics");
setMetrics方法调用的callMetrics:
public void startupUpdateMetrics(String userId, Context context) SharedPreferences sharedPreferences = context.getSharedPreferences("com.dmurphy.remotescrumpoker", Context.MODE_PRIVATE); db.collection("userteammetrics").document(userId).collection("teammetrics").document("generalteammetrics").get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() @Override public void onComplete(@NonNull Task<DocumentSnapshot> task) if (task.isSuccessful()) int teamCreated4 = sharedPreferences.getInt("teamCreatedForMetrics",0); Log.i(" => ", "Test4 " + teamCreated4); DocumentSnapshot document = task.getResult(); if (document.exists()) int teamCreated5 = sharedPreferences.getInt("teamCreatedForMetrics",0); Log.i(" => ", "Test5 " + teamCreated5); int oldAccepted = Integer.parseInt(document.get("accepted").toString()); int oldRejected = Integer.parseInt(document.get("rejected").toString()); int oldRequested = Integer.parseInt(document.get("requested").toString()); int oldsm2Appointed = Integer.parseInt(document.get("scrummaster2sappointed").toString()); int oldTeamsCreated = Integer.parseInt(document.get("teamscreated").toString()); int oldTeamsDeleted = Integer.parseInt(document.get("teamsdeleted").toString()); int oldTeamsMemberLeave = Integer.parseInt(document.get("memberLeave").toString()); int addAccepted = sharedPreferences.getInt("acceptedForMetrics",0); int addRejected = sharedPreferences.getInt("rejectedForMetrics",0); int addRequested = sharedPreferences.getInt("requestedForMetrics",0); int addsm2Appointed = sharedPreferences.getInt("sm2AppointedForMetrics",0); int addTeamsCreated = sharedPreferences.getInt("teamCreatedForMetrics",0); int addTeamsDeleted = sharedPreferences.getInt("teamDeletedForMetrics",0); int playersPerGame = sharedPreferences.getInt("noOfPlayersForMetrics",0); int addTeamsMemberLeave = sharedPreferences.getInt("teamsMemberLeaveForMetrics",0); Log.i("Test6 ", "startupUpdateMetrics: " + addAccepted + " " + addRejected + " " + addRequested + " " + addsm2Appointed + " " + addTeamsCreated + " " + addTeamsDeleted + " " + playersPerGame + " " + addTeamsMemberLeave); int newAccepted = oldAccepted + addAccepted; int newRejected = oldRejected + addRejected; int newRequested = oldRequested + addRequested; int newsm2Appointed = oldsm2Appointed + addsm2Appointed; int newTeamsCreated = oldTeamsCreated + addTeamsCreated; int newTeamsDeleted = oldTeamsDeleted + addTeamsDeleted; int newTeamsMemberLeave = oldTeamsMemberLeave + addTeamsMemberLeave; Log.i("Test7 ", "startupUpdateMetrics: " + newAccepted + " " + newRejected + " " + newRequested + " " + newsm2Appointed + " " + newTeamsCreated + " " + newTeamsDeleted + " " + newTeamsMemberLeave); db.collection("userteammetrics").document(userId).collection("teammetrics").document("generalteammetrics").update("accepted", newAccepted, "rejected", newRejected, "requested", newRequested, "scrummaster2sappointed", newsm2Appointed, "teamscreated", newTeamsCreated, "teamsdeleted", newTeamsDeleted, "memberLeave", newTeamsMemberLeave, "numberofplayerspergame" ,FieldValue.arrayUnion(playersPerGame)); );
LogCat(我不知道为什么它们都出现两次...因此,我认为可能是泄漏的线程):
