Android - IllegalStateException - Could not find a method startRhythmandAnimation in the activity class

由 爷，独闯天下 提交于 2019-11-26 22:12:49
问题 I can't understand why I'm getting this error message. My method IS in the activity class and the spelling is correct. 02-09 18:23:57.211: E/AndroidRuntime(19939): FATAL EXCEPTION: main 02-09 18:23:57.211: E/AndroidRuntime(19939): Process: stacy.example.assignment3_stacy_v1, PID: 19939 02-09 18:23:57.211: E/AndroidRuntime(19939): java.lang.IllegalStateException: Could not find a method startRhythmandAnimation(View) in the activity class stacy.example.assignment3_stacy_v1

问题 My app is map-centric. I call requestLocationUpdates() often. Once in a while, I get this exception when its called. Or in any other place which calls such method. I saw the solutions suggested on SOF, sadly nothing seems to work for me. Even if i call mLocationClient.connect() , there is no guarantee that it connects immediately, correct me if i'm wrong. How do i solve this problem? case R.id.btnContinue: gpsLocationDailog.cancel(); int isGooglePlayServiceAvilable = GooglePlayServicesUtil

Android - SQLite Cursor getColumnIndex() is case sensitive?

由 痴心易碎 提交于 2019-11-26 21:17:38
问题 While working with SQLiteCursor in Android i came to know that the getColumnIndex() is behaving case sensitive for example: Example: Column Name in DB was: Rules cursor.getColumnIndex("Rules") //workes fine cursor.getColumnIndex("rules") //throws error, see the error detail The documentation says nothing about that, for detail please see this. LogCat says: java.lang.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow. Make sure the Cursor is initialized correctly before

由 余生长醉 提交于 2019-11-26 21:06:46
This question already has an answer here: Simple Java regex matcher not working 2 answers Im trying to do a quick sanity check... and its failing. Here is my code - import java.util.regex.*; public class Tester { public static void main(String[] args) { String s = "a"; Pattern p = Pattern.compile("^(a)$"); Matcher m = p.matcher(s); System.out.println("group 1: " +m.group(1)); } } And what I would expect is to see group 1: a . But instead I get an IllegalStateException: no match found and I have no idea why. Edit: I also tries printing out groupCount() and it says there is 1. You need to invoke

When getting cell content using Apache-POI Library, I get both “Cannot get a numeric value from a text cell” and the reverse of that. How do I fix it?

问题 I realize the question is a little confusing, but I didn't know how else to word it. Anyway, here is the original code: private void readFile(String excelFileName) throws FileNotFoundException, IOException { XSSFWorkbook workbook = new XSSFWorkbook(new FileInputStream(excelFileName)); if (workbook.getNumberOfSheets() > 1){ System.out.println("Please make sure there is only one sheet in the excel workbook."); } XSSFSheet sheet = workbook.getSheetAt(0); int numOfPhysRows = sheet

问题 I encountered this error when I tried to run my application in Tomcat. I already checked the version of tomcat and java home. Both use java 6. Is there a missing jar? Or is it my web xml? I'm not using any maven tool.

I'm using the support library for my app. In my FragmentActivity I'm using an AsyncTask for downloading data from internet. In the onPreExecute() method I add a Fragment and in the onPostExecute() method I remove it again. When the orientation is changed in between, I get the above mentioned exception. Please take a look at the details: private class onFriendAddedAsyncTask extends AsyncTask<String, Void, String> { DummyFragment dummyFragment; FragmentManager fm; FragmentTransaction ft; @Override protected void onPreExecute() { Log.v("MyFragmentActivity", "onFriendAddedAsyncTask/onPreExecute");
