Members description:

FreeMem As Double
returns free memory available from heap
double memoryAvailable = Runtime.getRuntime().maxMemory() - (heapSize - heapRemaining) - nativeUsage;
FreeMem2 As Long
returns freeMemory
long freeMemory = (Runtime.getRuntime().maxMemory()) - (Debug.getNativeHeapAllocatedSize());
Garbage
Runs the Garbage Collector to free memory
Make sure your code is good first you are not initializing bitmaps aggressively
No amount of System.gc() calls will help a memory leak
You should split up the work and cache your data to file(s) and remove objects accordingly.
If you really need more memory you should run your java app with larger heap memory set
GlobalAllocSize As Long [read only]
returns getGlobalAllocSize;
GlobalFreedSize As Long [read only]
returns getGlobalFreedSize;
heapRemaining As Double
returns heapRemaining
Runtime.getRuntime().freeMemory();
heapSize As Double
returns totalMemory
Runtime.getRuntime().totalMemory();
HowBig (Directory As String, Filename As String) As String
HowBig(String Directory, String Filename)
returns height/width as one combined string variable
loadbitmap (Directory As String, Filename As String, reqWidth As Integer, reqHeight As Integer) As android.graphics.Bitmap
returns a simple bitmap
dont use file.dirassets ever, copy image over to another place from project
example: Activity.loadbitmap(mm.GetSafeBitmap(File.DirInternal,"/moon.jpg",Activity.height,Activity.width))
If this runs into memory problems, it's going to load a really low res image which will look bad
but it might not crash the app
loadbitmap2 (Directory As String, Filename As String, SampleSize As Integer, RGB565 As Boolean) As android.graphics.Bitmap
loadbitmap2(String Directory, String Filename, Integer SampleSize, Boolean RGB565)
returns a safe sized bitmap
dont use file.dirassets ever, copy image over to another place from project
example: Activity.SetBackgroundImage(mm.loadbitmap2(File.DirInternal,"/moon.jpg",8))
SampleSize, can be 2, 4, ,6, 8,....16, 32...etc
RGB565=True will set options.inPreferredConfig = Config.RGB_565;
MaxMem As Double
returns MaxMemory
Runtime.getRuntime().maxMemory()
nativeUsage As Double
returns free memory available from heap
Debug.getNativeHeapAllocatedSize();
