Can you paste in more information from your logcat view? It might help trace back to the root issue.

Hi John,

Can you copy and paste the contents in logcat into a new question? Let's revisit it there.

Hey Ben,

Here's my logcat view for the error "error opening trace file: No such file or directory (2)".. The app works fine till i call 4 blogs in NUMBER_OF_POST, but the moment i enter NUMBER_OF_POST=5; I get these errors in logcat.

09-19 10:38:17.827: E/Trace(812): error opening trace file: No such file or directory (2) 09-19 10:38:18.652: D/dalvikvm(812): GC_FOR_ALLOC freed 38K, 6% free 2556K/2716K, paused 86ms, total 93ms 09-19 10:38:18.682: I/dalvikvm-heap(812): Grow heap (frag case) to 3.217MB for 635812-byte allocation 09-19 10:38:18.762: D/dalvikvm(812): GC_FOR_ALLOC freed 2K, 5% free 3175K/3340K, paused 84ms, total 84ms 09-19 10:38:18.862: D/dalvikvm(812): GC_CONCURRENT freed <1K, 5% free 3188K/3340K, paused 24ms+16ms, total 103ms 09-19 10:38:19.442: D/libEGL(812): loaded /system/lib/egl/libEGL_emulation.so

I have also tried doing FORCE STOP several times, cleaning the project and also restarting the emulator but it doesn't seem to work.

Please help!!

This might be because of a known issue. Check out the Teacher's Notes on this page for a possible solution: http://teamtreehouse.com/library/build-a-blog-reader-android-app/getting-data-from-the-web/getting-json-data-from-an-http-request-2

Let us know in a new Forum post if that doesn't help, though!
