I have created a custom keyboard app My Input service looks like this Softkeyboard.java , My app is consuming high RAM around 150-200 MB,when I tried to dump memory info from
adb shell dumpsys meminfo
this is what I get even when my keyboard is not opened.

How to clear these views? I tried keep null to all view when keyboard is hidden but that is not working!!
I tried calling
android.os.Process.killProcess(android.os.Process.myPid());
it drops the memory consumption directly to 10 MB and clear all the views but in this case , my keyboard open very slowly.
Here is lifecyle,every time when I open keyboard (when I kill process on onFinishInputview) :
I/FA: App measurement is starting up, version: 9256
I/FA: To enable debug logging run: adb shell setprop log.tag.FA VERBOSE
I/FirebaseInitProvider: FirebaseApp initialization successful
I/MultiDex: install
I/MultiDex: VM has multidex support, MultiDex support library is disabled.
D/SoftKeyboard: onCreate invoked!
D/SoftKeyboard: onInitializeInterface invoked!
D/SoftKeyboard: onStartInput invoked!
Thanks
