Fatal Exception: android.database.CursorWindowAllocationException

[dasebasto]

There's a bug in the SDK, causing crashes on multiple devices and Android versions (at least from Lollipop to Nougat).

It's an uncaught exception:

Fatal Exception: android.database.CursorWindowAllocationException
Cursor window allocation of 2048 kb failed.

android.database.CursorWindow. (CursorWindow.java:108)
  | android.database.AbstractWindowedCursor.clearOrCreateWindow (AbstractWindowedCursor.java:198)
  | android.database.sqlite.SQLiteCursor.fillWindow (SQLiteCursor.java:138)
  | android.database.sqlite.SQLiteCursor.getCount (SQLiteCursor.java:132)
  | com.mobfox.sdk.logging.ReportsQueueDB.addCrashItemToMessage (SourceFile:269)
  | com.mobfox.sdk.logging.ReportsQueueManager$AddCrashAsyncTask.onPostExecute (SourceFile:1504)
  | android.os.AsyncTask.finish (AsyncTask.java:692)

I understand this happens during some kind of internal crash reporting.
SQLite exceptions should be caught then and not crash the whole app.

More details about the occurrences in production can be found here: http://crashes.to/s/81b4f1a7ab2

Thanks.

Hi,

This is a bug in our crash logger but it's actually stemming another crash that it tries to report. That crash may not be in our code.

We'll fix this problem in our upcoming release.

Any update / timeline ?

Thanks

Hello @dasebasto,
This bug was fixed. Can you please pull the last commit and let us know if your are still facing the same behaviour?

Thank you,

I updated my build.gradle with

implementation 'com.github.mobfox.MobFox-Android-SDK-Core:MobFox-Android-SDK-Core:3.6.3'
implementation 'com.github.mobfox.MobFox-Android-SDK-Core:MobFox-Android-SDK-AdMob-Adapter:3.6.3'

(coming from v3.6.1).

I get a new error about the library minSdk being set to 19.
I need to override this as my app has minSdk 15.

Can you please advise if things are done properly in MobFox SDK to avoid runtime crashes when SDK < 19 ?

[dasebasto]

OK, it seems to be the case in the AdMob adapter:

in class com.mobfox.adapter.MobFoxAdapter I found:

    public void requestBannerAd(Context context, final MediationBannerListener mediationListener, Bundle pubid, AdSize adSize, MediationAdRequest mediationAdRequest, Bundle mediationExtra) {
        if (VERSION.SDK_INT < 19) {
            mediationListener.onAdFailedToLoad(this, 3);
        }

Hello @dasebasto,
You can check out our documentation here:
https://mobfox.atlassian.net/wiki/spaces/PUMD/pages/354451655/Integrate+via+Android+SDK#IntegrateviaAndroidSDK-installation

"Note: The SDK supports Android API 19 and above.
In case your app has users with lower versions - in your manifest file include:
xmlns:tools="http://schemas.android.com/tools"

And add the following:
<uses-sdk tools:overrideLibrary="sdk.mobfox.com.mobfoxandroidadaptermopub,sdk.mobfox.com.mobfoxandroidadapteradmob,com.mobfox.sdk"/>

Once added, users with API 18 and below will receive "No-fill" message and the ad request will continue to the next network in the waterfall."

Thanks for confirming.

Apparently since last SDK update I also need to add "com.mobfox.sdk.all" to the list of overriden libs.
