Out of Memory

[francescodeliva]

I have experienced a permanent OutOfMemory calling this method: TiffBitmapFactory.decodePath(path);

It happens only on the following devices that I use to test Android 4.:

• Android 4.1.2 device (Galaxy Win)
• Android 4.4.2 (PadFone S - PF500KL)

This is the stack trace of the java.lang.OutOfMemoryError:

android.graphics.Bitmap.nativeCreate (Bitmap.java)

  | android.graphics.Bitmap.createBitmap (Bitmap.java:817)   | android.graphics.Bitmap.createBitmap (Bitmap.java:794)   | android.graphics.Bitmap.createBitmap (Bitmap.java:761)   | org.beyka.tiffbitmapfactory.TiffBitmapFactory.nativeDecodePath (TiffBitmapFactory.java)   | org.beyka.tiffbitmapfactory.TiffBitmapFactory.decodePath (TiffBitmapFactory.java:157)

I succeeded to avoid the OutOfMemory crash by setting this attribute of Options: options.inAvailableMemory = 20000000;

But the returned Bitmap is null.

How can I find a runtime value of options.inAvailableMemory that will work without returning a null bitmap?

Should I use this information? https://developer.android.com/reference/android/app/ActivityManager.MemoryInfo.html

Thanks Francesco

I used this algorithm to calculate max memory:

ActivityManager.MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();
ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
manager.getMemoryInfo(memoryInfo);
totalSystemByteAvailable = memoryInfo.totalMem;
treshold = memoryInfo.threshold;
options.inAvailableMemory = totalSystemByteAvailable - treshold;

We are going to test this code. Thanks
