runtime-error

问题 My app is not running on my devices except lollipop version :( I don't know exactly where the problem is. So cannot provide code :( I use ASyncTask, Content Resolver to query songs, Animation Drawable to start frame animation in the app. The only thing I get in the log is this, 07-22 21:52:58.919 8068-8068/app.farhanfarooqui.vocaplayer D/dalvikvm: Late-enabling CheckJNI 07-22 21:52:58.999 8068-8068/app.farhanfarooqui.vocaplayer D/ActivityThread: setTargetHeapUtilization:0.25 07-22 21:52:58

问题 I am reading a tab separated text file into pandas dataframe.I am getting a runtime error while reading this.I have gone through the posts related to this error and all of them are alluding to the rule that one should not modify dicts while iterating over them.In my case all I am doing is reading a file. How is this problem connected to an error of iterating and changing dicts ? >>> import pandas as pd >>> df=pd.read_csv("dummy_data.txt",header=None,chunksize=10000,error_bad_lines=False,warn

问题 I use vba on excel 2007, OS: windows vista, to make calculation using kinematic wave equation in finite difference scheme. But, when it runs the run-time 5 (invalid procedure call or arguments) message appears. I really don't what is going wrong. Anyone can help? Sub kwave() Dim u(500, 500), yy(500, 500), alpha, dt, dx, m, n, so, r, f, X, L, K As Single Dim i, j As Integer dx = 0.1 dt = 0.01 L = 10 m = 5 / 3 r = 1 f = 0.5 n = 0.025 so = 0.1 'this is slope alpha = 1 / n * so ^ 0.5 X = 0 For i

问题 I'm getting a vector iterators incompatible error during runtime. the line where it happens is at the very end of the code section, inside the for loop (humans.push_back( Human(&deck, (*iter)) );) When I first got the error, I was using a different iterator than 'iter' by mistake, so the runtime error totally made sense. But now that I changed it and recompiled everything (I double checked that), I still get this error. void BlackjackGame::getHumansAndHouse() { // asks how many players,

问题 I can't figure out what I'm doing wrong. I'm learning JPA mapping to a relational DB, by following some tutorials on the web, but can't find one that is straightforward. When I run my project, it gives me an error. I guess it's upon persisting em.persist(); . If I comment that line, all looks good, and no errors, but no data is written to table, obviously. Here's my code: persistence.xml (generated, untouched) <?xml version="1.0" encoding="UTF-8"?> <persistence version="2.1" xmlns="http:/
