Question

I have this exception that I get in my crash reports from Android:

java.lang.NoSuchMethodError: android.content.SharedPreferences$Editor.apply
at com.problemio.ProblemioActivity.first_time_check(ProblemioActivity.java:231)

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:636)
at dalvik.system.NativeStart.main(Native Method)

I am pretty new to the crash reporting system in Android. Why would this crash happen? I can not reproduce it on my device or the simulator.

What other info is needed from the crash report to determine the cause and how to fix this?

Thanks!

apply() was introduced in API level 9, and some devices that runs your app may be with lower version. consider changing this call to commit. As stated in the docs:

The SharedPreferences.Editor interface isn’t expected to be
implemented directly. However, if you previously did implement it and
are now getting errors about missing apply(), you can simply call
commit() from apply().
