when you are developing android application and find that your app is force close during the testing process, you can check the log on logcat to see what makes the app force close.
in eclipse to display logcat window go to Window > Show View > Other > Android > Logcat.
if you want to copy the logcat or save it into the file so that you can share it to other friends or pongodev support forum to help you solve the problem, you can block the logcat, block error code only. then select disk icon on the top right corner.
then, it will be saved on txt file.
