So, in order to remove the OutOfMemoryError, you need to remove memory leaks from your Android application….What may be the reasons for OutOfMemoryError?
- Use of Static view/context/activity.
- Register and unregister listeners.
- Non-Static inner class.
- Wrong use of getContext() and getApplicationContext()
What’s the difference between StackOverflowError and OutOfMemoryError?
StackOverflowError happens when you execute too many methods one inside another (for example with an infinite recursion), which is limited by the size of the stack. OutOfMemoryError happens when the JVM runs out of space to allocate new objects, which are allocated on the heap.
How do you handle bitmaps in Android as it takes too much memory?
Choose the most appropriate decode method based on your image data source. These methods attempt to allocate memory for the constructed bitmap and therefore can easily result in an OutOfMemory exception. Each type of decode method has additional signatures that let you specify decoding options via the BitmapFactory.
Which of these could potentially throw an OutOfMemory error?
OutOfMemoryError is a runtime error in Java which occurs when the Java Virtual Machine (JVM) is unable to allocate an object due to insufficient space in the Java heap. This error can also be thrown when the native memory is insufficient to support the loading of a Java class.
What is out of memory in Android?
Out of Memory (OOM) Error OOM error comes when the allocation crosses the heap limit or your process demand a amount of memory that crosses the heap limit. In Android, every application runs in a Linux Process. When some process demands a higher memory than its limit it causes a error i.e Out of memory error.
What is out of memory error?
“Out of memory” (OOM) is an error message seen when a computer no longer has any spare memory to allocate to programs. An out of memory error causes programs — or even the entire computer — to power down. The error means the computer no longer has any spare virtual memory for programs or hardware.
What is java garbage?

What is the difference between bitmap and drawable in Android?

What is inSampleSize in Android?
inSampleSize. Added in API level 1. public int inSampleSize. If set to a value > 1, requests the decoder to subsample the original image, returning a smaller image to save memory. The sample size is the number of pixels in either dimension that correspond to a single pixel in the decoded bitmap.
