Could not find class 'android.hardware.display.DisplayManager', referenced from method org.acra.collector.DisplayManagerCollector.collectDisplays

[Ashok Subedi]

Hi,

I tried to implement ACRA on my project on eclipse. I put the acra-4.9.0 jar file on libs folder, and followed the basic steps to send report to my google docs spreedsheet that matches the template provided.

My implementation is like this

@ReportsCrashes(formUri = "https://docs.google.com/spreadsheets/d/1ZdVI8xam7QTprpEEHeGWeDIctkqEpUYb3-TmrBI4W3M/edit?usp=sharing")

public class MyApplication extends Application {

....

@Override

    protected void attachBaseContext(Context base) {

        super.attachBaseContext(base);

        // The following line triggers the initialization of ACRA

        ACRA.init(this);

    }

}

ARCA catches error but doesn't send anything to my google docs. Following is my stacktrace

Anything I'm missing?

Yes, you shouldn't be included the ACRA jar.

You should be including the ACRA aar.

Note also that you should no longer be sending to a Google Docs spreadsheet.

But eclipse doesn't support ARR, so I unzipped and used the equivalent jar. I have very few clients so I won't be spamming google docs. So Google Docs doesn't work at all? 

Thank you so much for your response :)

There is more to an AAR than a JAR.

https://github.com/ACRA/acra/wiki/Notice-on-Google-Form-Spreadsheet-usage

"using Google Drive Forms as the ACRA reporting endpoint will not be
supported anymore"

That page lists various options for where to send your crash reports.

Thank you. I will use other options to Google docs. But how do I use AAR on eclipse? Stackoverflow suggests to unzip to Jar and use it. Any suggestions?

Use an AAR-aware build system (Gradle, Maven) and an IDE to match.

[F43nd1r]

While it is the preferred solution to use the aar, it is in fact possible to use the jar (again: it it highly discouraged to do so).
At the moment ACRA only uses one of the additional features of an aar, which is the AndroidManifest. If you copy the manifest entries in addition to the jar, it should work.
We don't support this usage and it might be broken in future releases without further notice.

However these errors look different from this problem anyway.
There are classes and methods missing on the classpath which should never be missing in the given scenario.
I know of 3 causes for this:
a) the device is no Android device (however this would probably lead to an earlier crash)
b) the device reports a wrong Build.VERSION.SDK_INT
c) the device runs a custom (and inherently broken) ROM

My app runs on Samsung galaxy tab 2 (10.1). I will try these solutions and keep  you guys posted. (I generated crash myself to test the application). The install is not from google play but my local debugging app (it should't be an issue right?). I haven't modified device.

Thank you so much for your help.
