1. Code to obtain the current app memory usage

ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
     //Maximum allocated memory
     int memory = ();
     ("memory: "+memory);
     //Maximum allocated memory acquisition method 2
     float maxMemory = (float) (().maxMemory() * 1.0/ (1024 * 1024));
     //The total memory currently allocated
     float totalMemory = (float) (().totalMemory() * 1.0/ (1024 * 1024));
     //Remaining memory
     float freeMemory = (float) (().freeMemory() * 1.0/ (1024 * 1024));
     ("maxMemory: "+maxMemory);
     ("totalMemory: "+totalMemory);
     ("freeMemory: "+freeMemory);

result

: memory: 256
: maxMemory: 256.0
: totalMemory: 11.974937
: freeMemory: 3.6257935

This shows that the maximum allocated memory of my app on the mobile phone is 256m, and now it has allocated 11m. 6m of these 11m are free.

Of course, Monitors can view memory usage more intuitively

2. Use the dos command

(1) Open the dos window and execute the adb shell

(2) dumpsys meminfo package name

result:

3. Use Monitors or DDMS

monitors
