Because demand is said to meet maximum pixel image rendering, but a larger load need more memory, so I must need to make a judgment and prevent oom, surfing the web, found by the following code can get the maximum available memory app

 public static float getMaxMemory () {
Return the Runtime. GetRuntime (). MaxMemory ()/1024 f/1024 f. 
} 

 public static ActivityManager. MemoryInfo getMemoryInfo (Context Context) {
If (the context==null) {
return null; 
} 
ActivityManager. MemoryInfo mi=new ActivityManager. MemoryInfo (); 
((ActivityManager) context. GetSystemService (context. ACTIVITY_SERVICE)). GetMemoryInfo (mi); 
Return the mi; 
} 

 val manager=(enclosing getSystemService (Context. ACTIVITY_SERVICE) as ActivityManager) 
Val heapGrowthLimit=manager. MemoryClass 

After tests found that the return of maximum available memory is 512 m, but, I in the Android Studio by looking at the inside of the profiler memory module, you can see my app has more than 1 gb of memory
Clear and 512 m not ah, that what can get the largest number of memory?
