Android cache background process is increasing continuously

Question

In my android application named "PriceDekho" the cache background process takes too much space. First when i start the application the application takes arround 30MB (I think its OK) but the problem is when i surfing the application pages then this size is increasing continuously upto (200 MB). This appliction "Cache background process" also varying with the mobile RAM size. If the mobile RAM size is 2GB then this application "Cache background process" size goes upto 500 to 700 MB.

My application is having only 5 to 6 screens. I just need to stabilize the cached background size.

How can i clear the application cached size? Please help.

It sounds like you have memory leaks which the Garbage Collector can not remove. For example if you need to have a reference to the Context from a non-context class which is never released there. Most of the time Android Studio will point those out but you can try to use LeakCanary and search for them.

Add the dependency

dependencies {
   debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5.1'
 }

and use it in your Application class. Create one if you don't have it already.

public class ExampleApplication extends Application {

  @Override public void onCreate() {
    super.onCreate();
    if (LeakCanary.isInAnalyzerProcess(this)) {
      // This process is dedicated to LeakCanary for heap analysis.
      // You should not init your app in this process.
      return;
    }
    LeakCanary.install(this);
    // Normal app init code...
  }
}
