Re: [mapsforge-dev] Mapsforge Crash on on some devices

[Ludwig]

This is an issue that affects 4.2 devices, there is a fix for it on github. I am away from computer, but it should be easy to find.

I'm getting crash reports on a particular device, Nexus 7 tablet.
I haven't seen this on other devices and it hasn't been an issue except on this device.

The map won't display.  Is there something I can do to prevent this?
Is there a buffer size I can adjust or view?

java.lang.RuntimeException: Buffer not large enough for pixels
at android.graphics.Bitmap.copyPixelsToBuffer(Bitmap.java:381)

Thanks is advance

To quote the good guy that supplied the patch (do not remember the name):
-----------------------
Patch is simple:

in trunk/mapsforge-map/src/main/java/org/mapsforge/android/maps/mapgenerator/InMemoryTileCache.java

add:

Bitmap pooledBitmap = this.bitmapPool.remove(this.bitmapPool.size() - 1);

+ this.byteBuffer.rewind();

bitmap.copyPixelsToBuffer(this.byteBuffer);
this.byteBuffer.rewind();
pooledBitmap.copyPixelsFromBuffer(this.byteBuffer);

-----------------------

Cheers,
Andrea

Just checked, i think the actual change fell into the transition to github, but it should be included in the current head. You should be able to use the current build on ci.mapsforge.org
