Trying to insert bulk of data
-----------------------------
Key: CB-461
URL: https://issues.apache.org/jira/browse/CB-461
Project: Apache Callback
Issue Type: Bug
Components: Android
Affects Versions: 1.5.0
Environment: Android, Cordova, JQuery Mobile
Reporter: Jawwad Farooq
Assignee: Joe Bowser
I tweaked Storage.java class to use it for database related work instead of
WebSQL for Android. Everything is working fine unless I have requirement to
insert more than 600 rows in a go. When I tried to insert so many rows, around
500 rows were inserted successfully but after that following error occurs:
W/dalvikvm(16890): ReferenceTable overflow (max=512)
W/dalvikvm(16890): Last 10 entries in JNI local reference table:
W/dalvikvm(16890): 502: 0x44a9e110 cls=Ljava/lang/String; (28 bytes)

W/dalvikvm(16890): 3 of Ljava/lang/String; 36B (2 unique)
W/dalvikvm(16890): 1 of Lcom/nubinews/reader/Reader$RuntimeJSInterface; 12B
W/dalvikvm(16890): Memory held directly by tracked refs is 12344 bytes
E/dalvikvm(16890): Failed adding to JNI local ref table (has 512 entries)
..... and so on. Then I tried to figure out is this the problem of
SQLiteDatabase class or some Cordova related. So I commented out the actual
database insertions in Storage.java. But the problem persisted.
So, I came to a point that if you call a plugin for more than 512 times from a
single Javascript method, this exception will occur. Kindly look it in to this
issue and let me know as I am badly stuck at this point.
Thanks for your time.
