Hi there,
I'm trying to get some form of automatic crash reporting working for the app
I'm developing using http://code.google.com/p/acra/ acra . I've
successfully created a callable wrapper for the acra-4.2.3.jar and my
project builds, runs, and appears to call ACRA.Init() without any problems.
The main trouble I have is how to translate the annotation syntax from Java
to C#. I.e. In a java app, you specify the google form to send crash reports
to using this syntax:
@ReportsCrashes(formKey = "dGVacG0ydVHnaNHjRjVTUTEtb3FPWGc6MQ")
public class MyApplication extends Application {
...
}
I see M4A 4.2 has support for annotations but the generated ACW doesn't seem
to contain any 'ReportsCrashesAttribute'.
To work around this, I tried to create a 'GoogleFormSender' explicitly
passing the form key as a construction parameter, but discovered the
'addReportSender' method is missing in the wrapper.
So I tried the following instead:
IntPtr java_class_handle = IntPtr.Zero;
IntPtr class_ref = JNIEnv.FindClass ("org/acra/ErrorReporter", ref
java_class_handle);
IntPtr method = JNIEnv.GetMethodID(class_ref, "addReportSender",
"(Lorg/acra/sender/ReportSender;)V");
JNIEnv.CallVoidMethod(Org.Acra.ErrorReporter.Instance.Handle, method,
new
JValue(new Org.Acra.Sender.GoogleFormSender(FormKey)));
This appeared to work, but when I try to report an error using:
Org.Acra.ErrorReporter.Instance.HandleSilentException(new
Throwable("Test
Problem"));
Logcat reports that it failed:
E/Visions Live BB(30458): Failed to send crash reports
E/Visions Live BB(30458): java.lang.NullPointerException
E/Visions Live BB(30458): at
org.acra.sender.GoogleFormSender.remap(GoogleFormSender.java:73)
E/Visions Live BB(30458): at
org.acra.sender.GoogleFormSender.send(GoogleFormSender.java:52)
E/Visions Live BB(30458): at

E/Visions Live BB(30458): at
org.acra.ErrorReporter.checkAndSendReports(ErrorReporter.java:960)
E/Visions Live BB(30458): at
org.acra.ErrorReporter$ReportsSenderWorker.run(ErrorReporter.java:142)
>From looking through the ACRA source code this is because the ACRA static
class has a null pointer to a 'ReportsCrashes' object that it would normally
get from the annotation.
So anyway, I was wondering if anyone has had any luck with automatic crash
reporting in a M4A project, and whether they could give me a leg up this.
I see in this post:
http://mono-for-android.1047100.n5.nabble.com/How-can-I-use-bug-trackers-like-Acra-or-BugSense-td5157636.html
that there are issues with unhandled exceptions not being caught but I was
planning to use high level "catch all" exception handlers that would report
anything caught as a crash.
Any help much appreciated,
Paul
