java - Detecting Memory and CPU consumption of a particluar app -

-

i want detect memory , cpu consumption of particular app in android (programmatically), can 1 me it. have tried top method, want alternative it.

any appreciated, :)

if wan trace memory usage in app there activitymanager.getmemoryinfo() api.

cpu usage can traced using cpustatscollector api.

for more informative memory usage overview, outside app, can use adb shell dumpsys meminfo <package_name|pid> [-d] more specific memory usage statistics. example, there the command com.google.android.apps.maps process:

adb shell dumpsys meminfo com.google.android.apps.maps -d

which gives following output:

** meminfo in pid 18227 [com.google.android.apps.maps] **                pss  private  private  swapped     heap     heap     heap              total    dirty    clean    dirty     size    alloc     free             ------   ------   ------   ------   ------   ------   ------ native heap    10468    10408        0        0    20480    14462     6017 dalvik heap    34340    33816        0        0    62436    53883     8553 dalvik other      972      972        0        0     stack     1144     1144        0        0   gfx dev    35300    35300        0        0 other dev        5        0        4        0  .so mmap     1943      504      188        0  .apk mmap      598        0      136        0  .ttf mmap      134        0       68        0  .dex mmap     3908        0     3904        0  .oat mmap     1344        0       56        0  .art mmap     2037     1784       28        0 other mmap       30        4        0        0 egl mtrack    73072    73072        0        0 gl mtrack    51044    51044        0        0   unknown      185      184        0        0     total   216524   208232     4384        0    82916    68345    14570

java - Two interface have same method name with different return type -

this question understanding interfaces in java. here simple example of implementing interfaces in java. interface parenta { void display(); } interface parentb { int display(); } class child implements parenta, parentb { @override public void display() { system.err.println("child parenta"); } //error : return type incompatible parentb.display() //so added method int return type @override public int display() { system.err.println("child parentb"); } } this case can happen in large java application 2 interface can have method same name. thought since return type different jvm know interface's method overriding. what best explanation this? situation make sense? thanks in advance because method same signature not allowed, confuses compiler detect exact override-equivalent method declared once. jls (§8.4.2) 2 methods or constructors, m , n, have same signature if have, ...
