Hello,
Our configuration:
* *Cordova version 6.3.1 *
* *Cordova Android platform version 5.2.2.*
We are running the Cordova app on Android 4.4.2.
We are using following memory profiling tools:
* *Chrome developer tools*
* *System Monitor Android App*
* *System Info for Android*
Same scenario we have observed with a Cordova Test Application (Default
app when we create a Cordova project for Android)
In our Test Application, we have a button which initiates web page
(chromium browser) . On Button click whenever the Cordova web page is
loading it is taking close to ~42MB of memory. Now if we exit from the
cordova page and back to android native screen that MB is not fully
recovered. If we continue this type of testing i.e, entering and exiting
from the cordova page continuously is causes a huge memory leak in our
app. On each click we have found ~1MB memory is increased when Cordova
page is reloaded.
_*Queries:*_
1. Default browser of Cordova is *Chromium*. Is there any other way to
change the default browser for Android Applications?
2. Android 4.4.2 version is using the *chromium version 30.0.0.0*. Does
this version of Chromium version have any leaks?
3. We are using "_*sendPluginResult*_" API in a repeated interval (say
after every 200ms) to send the data from "Native JAVA" side to the
"JAVA Script" side. Do you think it may cause any huge memory
consumption?
4. Please suggests if there are any other *Memory Profiling tools*
which can be used in our environment.

> Huge memory usage in Cordova android platform

> Key: CB-12634

> Project: Apache Cordova
> Issue Type: Bug
> Components: Android, Browser, CordovaLib

> Our application consist of following components:
> 1. Android Native code + Java Jar
> 2. CordovaLib + Own created Cordova plugin
> 3. JavaScript, HTML, CSS
> In our android screen we have a button which initiates web page (chromium
> browser) where we need to draw some graphs and digits on a certain interval.
> Those data are receiving in Android native end from a remote device & we are
> passing those data to the web page through cordova plug-in.
> On Button click we are initiating Cordova plug in along with web page.
> whenever the plugin is initiating and the Cordova web page is loading it is
> taking close to 50MB of memory.
> Now if we exit from the cordova page and back to android native screen that
> 50MB is not fully recovered. If we continue this type of testing i.e,
> entering and exiting from the cordova page continuously is causes a huge
> memory leak in our app.
> Questions:
> 1. Is it the usual behavior in cordova?
> 2. As multiple Threads are running in CordovaLib framework, so when we are
> exiting from cordova screen what is the status of those internal Threads? Are
> those threads still running in the background even if we are exiting from
> cordova webview to android native page?
