java.lang.IllegalStateException: attempt to re-open an already-closed object(Tried closing )

android, android-sqlite, sqlite

Solution

You should call `getCount()` before you close your cursor.

Move:

if(cursor != null && !cursor.isClosed()){
    cursor.close();
} 

below:

 cursor.getCount();

like this:

public int getRecordsCount() {
    int count = 0;
    String countQuery = "SELECT  * FROM " + TABLE_LOGIN;

    SQLiteDatabase db = this.getReadableDatabase();
    Cursor cursor = db.rawQuery(countQuery, null);



    if(cursor != null && !cursor.isClosed()){
        count = cursor.getCount();
        cursor.close();
    }   
    return count;
}

Problem

``` public int getRecordsCount() { String countQuery = "SELECT * FROM " + TABLE_LOGIN; SQLiteDatabase db = this.getReadableDatabase(); Cursor cursor = db.rawQuery(countQuery, null); if(cursor != null && !cursor.isClosed()){ cursor.close(); } // return count return cursor.getCount(); } ``` I am trying to get the totalnumber of records in the database, but the database is getting crashed everytime with `java.lang.IllegalStateException: attempt to re-open an already-closed object: android.database.sqlite.SQLiteQuery (mSql = SELECT * FROM login)` . Please help me with the error ``` 03-05 22:23:14.208: E/AndroidRuntime(4988): FATAL EXCEPTION: main 03-05 22:23:14.208: E/AndroidRuntime(4988): java.lang.IllegalStateException: attempt to re-open an already-closed object: android.database.sqlite.SQLiteQuery (mSql = SELECT * FROM login) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.database.sqlite.SQLiteClosable.acquireReference(SQLiteClosable.java:34) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.database.sqlite.SQLiteQuery.fillWindow(SQLiteQuery.java:64) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.database.sqlite.SQLiteCursor.fillWindow(SQLiteCursor.java:283) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.database.sqlite.SQLiteCursor.getCount(SQLiteCursor.java:264) 03-05 22:23:14.208: E/AndroidRuntime(4988): at com.ecomm.android.sqlite.DatabaseHandler.getRecordsCount(DatabaseHandler.java:123) 03-05 22:23:14.208: E/AndroidRuntime(4988): at com.ecomm.android.LaunchActivity.DataBaseImplementation(LaunchActivity.java:120) 03-05 22:23:14.208: E/AndroidRuntime(4988): at com.ecomm.android.LaunchActivity.onClick(LaunchActivity.java:98) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.view.View.performClick(View.java:2408) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.view.View$PerformClick.run(View.java:8816) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.os.Handler.handleCallback(Handler.java:587) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.os.Handler.dispatchMessage(Handler.java:92) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.os.Looper.loop(Looper.java:123) 03-05 22:23:14.208: E/AndroidRuntime(4988): at android.app.ActivityThread.main(ActivityThread.java:4627) 03-05 22:23:14.208: E/AndroidRuntime(4988): at java.lang.reflect.Method.invokeNative(Native Method) 03-05 22:23:14.208: E/AndroidRuntime(4988): at java.lang.reflect.Method.invoke(Method.java:521) 03-05 22:23:14.208: E/AndroidRuntime(4988): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:876) 03-05 22:23:14.208: E/AndroidRuntime(4988): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:634) 03-05 22:23:14.208: E/AndroidRuntime(4988): at dalvik.system.NativeStart.main(Native Method) 03-05 22:23:15.608: I/binder_sample(4988): [android.app.IActivityManager,2,1395,com.ecomm.android,100] 03-05 22:23:15.608: I/binder_sample(4988): Unknown binary event type 110 03-05 22:23:15.608: I/binder_sample(4988): Binary log entry conversion failed ```
