More on this Exception. I triggered it accidently by quitting and
relaunching my app quickly and got the following logcat
Application.onCreate() is called
...
08-25 15:41:33.003: WARN/ActivityThread(16118): ClassLoader.loadClass: The
class loader returned by Thread.getContextClassLoader() may fail for
processes that host multiple applications. You should explicitly specify a
context class loader. For example:
Thread.setContextClassLoader(getClass().getClassLoader());
...
...soon after at init when the first AsyncTask is loaded:
08-25 15:41:39.179: WARN/dalvikvm(16118): Exception
Ljava/lang/RuntimeException; thrown while initializing
Landroid/os/AsyncTask;
...
...and boom a bit later:
08-25 15:41:46.152: ERROR/ACRA(16118): java.lang.NoClassDefFoundError:
android.os.AsyncTask
<rest of backtrace>
So the classloader failed to load android.os.AsyncTask from which we are
warned it may happen from the initial warning.
I could not find this message anywhere in Android source but I'm using
CyaonogenMod7.
My app has a Service from another package that is run in the same process
than the app package. To make the warning disappear about the classloader I
had
to add
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
as the first line of entry point functions of both packages running in the
same process (it would still appear if done in one package but not the
other).
Has anyone a more detailed explanation of this behaviour and if the above
actually fix it ?
