Android : Way To Control An App's Cache Size?

Aug 10, 2010

My app has a WebView which displays Google maps. I'm trying to limit the cache size to a reasonable one - like 2MB. After checking with settings->applications->manage applications I found out that regular page load gets the cache to 900kb. And dispite my efforts, I can't limit the cache size or monitor when the cache limit is being reached. If I'm playing with the map on the webview, the app can even reach 10MB and no "ache max size reached" message is received.

Android :: Android - Image Cache Stategy And Memory Cache Size

Jun 21, 2010

I'm implementing an image cache system for caching downloaded image.

My strategy is based upon two-level cache:
Memory-level and disk-level.

My class is very similar to the class used in the droidfu project

My downloaded images are put into an hashmap and the Bitmap objet is wrapped inside a SoftRererence object.

Also every image is saved permanently to the disk.
If a requested image is not found into the Hashmap<String,SoftReference<Bitmap>> it will be searched on the disk, readed, and then pushed back into the hashmap. Otherwise the image will be downloaded from the network.

Since I store the images into the phisical device momery, I have added a check for preserve the device space and stay under a 1M of occupied space:

CODE:.................

This method is called sometime afte a disk writing:

CODE:..............

What I'd like to add is the same check on the HashMap size to prevent it will grow too much. Something like this:

CODE:.....................

My question is:
What could be a right MAX_MEMORY_SIZE value? Also, Is it a good approach? A good answer also could be: "Don't do it! SoftReference is already enough"

Android :: Configure The Web Browser Cache Size?

Jul 30, 2009

Configure the web browser cache size? In HTC's new product HERO, they limit the cache size from 100KB to 6MB, and user can configure it manually. It can prevent browser sucking up memory space too much.

General :: How To Limit Cache Size

Jun 9, 2012

I do really love cloud computing... But, Google seems to have forgot something: set a limit to the cache size.

I have a Nexus S and my poor 16Gb internal memory is saturated because of caches: Google+, Android Gallery (Picasa), Google Music and Google Listen all fight for the sdcard space.

The only apps who have explicit cache settings is Google Listen... The others don't have obvious options. I have 10K songs, 10-20K photos, etc.. I need to access them, but I need to limit the cache size.

Is there a way to easily limit cache size per apps?

General :: Google+ Application Cache Size Is Huge?

Jan 15, 2012

I went to do a nandroid backup and it failed, "no space on my SD card".

Thats weird, as usually have at least 4 gig on my Nexus S 4g.

Poking around, it was the cache from Google plus,).[url].... That, coupled with my titanium backup of same ate my SDCARD. easy to fix Titanium from backup it up, but the cache is still several gigs large. 40,000 + files with [number].screen extensions.

I have like 2 friends on google+, 3 posts, and can not for the life of me figure out what in the world all that data is.

I'm going to remove the data , freeze the app, but just wanted to know if noticed a disproportionate amount of data in the Google+ app compared to the amount of activity/usage I have on google+.

Android :: Programmatically Control Size Of Child View In AbsoluteLayout

Feb 18, 2009

The documentation at http://code.google.com/android/reference/android/widget/AbsoluteLayout.html says:
onLayout(boolean changed, int l, int t, int r, int b) //Called from layout when this view should assign a size and position to each of its children. So I overrode it like this:

@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
Log.d("test", "In MainLayout.onLayout");
int childCount = getChildCount();
for (int childIndex = 0; childIndex < childCount; childIndex++) {
getChildAt(childIndex).setLayoutParams(new LayoutParams(100, 100, 100, 100));
}
super.onLayout(changed, l, t, r, b);
}

I am declaring the child elements (buttons) in the XML for the layout. This correctly sets the position of the buttons but not the size. The size is being taken from what is defined in the XML (it's a required attribute).

Android :: Create ADT Virtual Machine Of Specific Size That Still Has Hardware Control Buttons

Aug 9, 2010

I'm trying to develop a very specific app for my Dell Streak. I want the entire app to run landscape. The Streak has a tilt function that switches the whole OS to a landscape 800x480.

So I want to make an ADT to test in that uses an 800x480 display, but whenever I set the size I get no buttons. The Streak has a Home, Menu and Back button aswell as volume/mute and power, and I need to use some of them for my application.

I'm not worried about the tilting messing up my application. Not yet, anyway. Just need the test environment the right size and with buttons.

Android :: How Do I Make My Image View Fixed Size Regardless Of Size Of Bitmap

Sep 23, 2010

So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file

Android :: About Size Of Resource Assets Files & Final Apk Size

Oct 2, 2009

I am currently developing a dictionary application with voice database. I would like to know about the current Android limitation on the file size. I am using a self-provided sqlite database ( > 50mb ) . I tested that once the built .apk size exceeds ~30mb the app will not be installed onto the simulator (INSTALL_FAILED_ INSUFFICIENT _STORAGE). Could anyone confirm me that if up until now there is no way to embed such large size files in a single apk ( Aimed to sell at Google Market without requiring user to download datafile afterwards). Also, is there a limitation of 1,048,576 bytes for a single file in the assets folder ?

Android :: Installed Application Size Vs APK File Size

Jul 8, 2010

Can somebody explain to me what makes up the installed application size? I have an apk that is about 8 MB, and often when I install I get the INSUFFICIENT_STORAGE error. I have around 25-30 MB free space on the phone. I'm doing debugging so I have to upload lots of new versions. If I uninstall the previous version then I can install the new version. The application manager claims that the app is taking up 22 MB. So back to the original question, how come the app is taking up 22 MB when it really only is 8 MB?

Android :: Png Downloaded Size Different To Server Size?

Oct 7, 2010

My app downloads .png files to the sd card for later use. I kept getting OutOfMemoryErrors (if anyone could explain this too, that'd be great!) and so I took a look at the sizes of the images saved to the sd card, and they seem to be roughly double what they are on the server. Why is this, and how can I make them smaller?
public void onCreate(Bundle saved)
setContentView(R.layout.namedrxnscreen);
TextView t1 = (TextView)findViewById(R.id.rxn_text1);
TextView t2 = (TextView)findViewById(R.id.rxn_text2);
TextView t3 = (TextView)findViewById(R.id.rxn_text3);
TextView t4 = (TextView)findViewById(R.id.rxn_text4);
iv = (ImageView) findViewById(R.id.rxn_image);
pb = (ProgressBar) findViewById(R.id.rxn_loading);
vs = (ViewSwitcher) findViewById(R.id.rxn_switch);

Motorola Droid : Font Size And A Spell Checker - Imposiible To Read Small Font Size In Emails Or Text Messages

Dec 26, 2009

This is my first post. I've had a Moto Droid since day one, and I just love it. It is without a doubt better than any phone that I've had over the years, and that includes the iPhone, BB, etc.

However, there are 2 things that I don't understand - Font size and a spell checker. It is imposiible to read the small font size in emails or text messages.

1. Why has there not been an app to either change the font size or be able to zoom in? Picasy has incorporated multi-touch for zooming, so I've to assume that its doable! Why not have the same in an email client.

2. Why is there not an email client out there that allows for spell checking? There are many such apps for the BB! I am a terrible speller.

I am not complaining, I just want to understand the limitations from a developers prospective, as I am sure these isuues will eventually be addressed.

Android :: How To Size Android Components According To Image Size Using XML

Feb 10, 2009

I have created a custom icon bar in Android using the XML layout creator, using a RadioGroup within a LinearLayout (XML included below). Each RadioButton within the RadioGroup has a custom drawable (with checked and unchecked states) as its android:button attribute. The Linear layout is itself within a RelativeLayout so that it can appear at an arbitrary position on the screen (as a side bar, in this instance).The drawables are 55 pixels wide, and the android:layout_width attribute of all these views is "wrap_content".When I make this component visible, aligned to the bottom-left of the screen, only about three-quarters of the RadioButton image widths are visible. Setting the layout_width of the RelativeLayout to "fill_parent" rectifies this and causes the full button to appear.However this means that the button group consumes click events across the entire width of the screen. How can I make the entire button appear, and have only the area of the button respond to clicks? Hard-coding the width of the drawable is not a particularly desirable solution.<RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width ="wrap_content" android:layout_height="wrap_content"> <LinearLayout android:id="@+id/LinearLayout02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_below ="@+id/LinearLayout01" android:visibility="invisible"><RadioGroup android :id ="@+id/ RadioGroup01" android:layout_height="wrap_content" android:checkedButton="@+id/RB01" android:layout_width="fill_parent">
<RadioButton android:id="@+id/RB01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:button="@drawable/DR01"/><RadioButton android:id="@+id/RB02" android:layout_width="fill_parent" android:layout_height="wrap_content" android:button="@drawable/DR02"/>
<RadioButton android:id="@+id/RB03" android:layout_width="fill_parent" android:layout_height="wrap_content" android:button="@drawable/DR03"/> <RadioButton android:id="@+id/RB04" android:layout_width="fill_parent" android:layout_height="wrap_content" android:button="@drawable/DR04"/> </RadioGroup></LinearLayout>

Do you have a work around ?

Android :: Cant Clear Cache On Some Apps

For example Zumodrive and repligo reader both will show 20+mb in my settings, but clear cache is greyed out and shows 0mb. However when I delete these apps and reinstall them, I get all that internal memory back. I am running a rooted Nexus One.

Android :: Counting Files In A Cache

Nov 3, 2010

I'm trying to manage the files that I store in a local cache. I download files, then delete them after the total file size in the cache exceeds a certain number of bytes. What I'm shooting for right now is something simple: setting the max cache size to be 1 MB, or 1*1024*1024 bytes = 1048576 bytes. I have a method that gets the cache directory, then does a listFiles() on that File to get all children of the directory. I have a flat cache structure, no subdirectories, so simply calling f.length() on every child should give me my total cache size right?

Well what I'm finding is that the amount I count is about 0.9 of size reported in Manage Applications > Application Info for my app, in the Cache section.

Am I making a bad assumption that File.length() will actually return to me the size, in bytes, of a file on disk? I also wonder also if disk space in the Cache directory is being used by Android at all for some reason I'm unaware of.
