How To Deal With Out oF Memory Exception In Android
In this blogs we have explained about memory exception and how to deal with “out of memory
exception in android”. In android we encounter with ​out of memory exception​ many times. The
reasons are we don't have expanding memory and completely dependent on the available phone
memory. So we don't have control over external factors and will need to optimize memory at our
end.
Reasons of Out of Memory Error ::
1.Biggest reason is memory leak i.e, Context leaking or can say Activity Leaking,a Service has the
same problems as Activity in this regard.
2.You are doing process that demands continuous memory and at a point it goes beyond max
memory limit of a process.
3.When you are dealing with large Bitmap and load all of them at run time.
There are some technique to optimizing the memory ::

2. ​ 1.Flag Technique : ​A solution is to set android:hardwareAccelerated=”true” and
android:largeHeap=”true” It is available after android 3.0 and so many android devices still run on
gingerbread(2.3+) so it is not a reliable solution.
​2.DVM garbage collection (Memory Leakage) : ​DVM Garbage collection works same as JVM
garbage collection, Make sure that whenever you are done with object and dont need it anymore, so
reference as null.
3​.Out of memory exception when we load image on imageview in our listview.Images come in all
shapes and sizes.In many cases It might be larger than required for a typical appication UI. When
Decode Image normally::
1. StringsdImage="/sdcard/imageTesting/"+imageTestName;
2. Bitmapbitmap=BitmapFactory.decodeFile(sdImage);
Most of the Time It give Out of memory Exception when image size is large. So we can use bitmap
Option.
1. StringsdImage="/sdcard/imageTesting/"+imageTestName;
2.
3. BitmapFactory.OptionsourOptions=null;
4.
5. options=newBitmapFactory.Options();
6.
7. ourOptions.inSampleSize=2;
8.

3. 9. Bitmapbitmap=BitmapFactory.decodeFile(sdImage,null,ourOptions);
But It is not the Best Solution….
