Byte[] And Java.lang.outofmemoryerror Read/write File By Bits

I working on wiping some free space in android. Here is my code: private void creatingFileDelete(int size, int passMode) { File lastFile = new File(Environment.getExte

Solution 1:

OutOfMemoryError 

Thrown when a request for memory is made that can not be satisfied using the available platform resources. Such a request may be made by both the running application or by an internal function of the VM(Virtual Machine)

when you get error like OutOfMemory it means you are running out of memory for the application as your app consumes more space then allocated to it by the system.

put this attribute android:largeHeap="true" in the the <application/> atgin the manifest.xml file

for example

 <application
    android:name="support.classes.StartUp"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:largeHeap="true"// you are increasing the heap space for the app 
    android:theme="@style/AppThemeTest">

if you simple want to free some space it would be better to let Android system handle it which knows the best

System.gc()

call garbage collector before you do any memory consuming task as that will free some space for you. if you try to call this after your task then it serves no purpose
