Android :: How To Launch Market Intent In 'Give Feedback' Mode?

May 23, 2010

I have just written a game for the Android market and would like to remind my customers to leave feeback on the market for the application (especially the demo version.) Is there any way to launch the market intent in a mode that will take the user to the feedback / comments section of the page?I already use this approach for linking my demo to the paid app.

Is there a best practice that any Android devs out there might know of?Additionally, is there any way to track referalls from my demo app so that I can try to calculate some kind of a conversion rate? (i.e. how effective the demo app is at generating sales.)

Android : Forward Activity Result To Parent With SingleTop Launch Mode?

Jun 1, 2010

I have two activities: a MainListActivity, and a DetailViewActivity. DetailViewActivity is set with android:launchMode="singleTop".

When clicking an item in the "main list" activity, it launches the "detail view" activity via:

startActivityForResult(detailIntent, REQUEST_CODE_DETAIL);

If I then call setResult(RESULT_OK, resultData); and finish(); from within the Detail activity, that resultData is received by the "main list" activity's onActivityResult(..) method correctly.

However, if I implement a "see previous"/"see next" type of navigation within the Detail activity, and implement it using singleTop, that result no longer gets sent back to the initial activity:

Intent nextItemIntent = this.createIntent(nextId);
// at this point, my DetailActivity's onNewIntent() method is called, and the new data is loaded properly

But from here, when I call setResult(..) and finish(), my MainList activity never receives the new/updated result. Anyone know what I'm doing wrong?

Android :: Disadvantage To Using High Resolution Image Resources For Application?

Mar 9, 2010

The Android documentation says that best practices are to make two drawable directories - one for HDPI and one for MDPI. It also says that if the MDPI directory doesn't exist and a MDPI device is running the app, it will scale down the HDPI ones so everything looks good. Is there any reason not to just make one high resolution set of graphics? One con that I can think of is performance issues and one pro I can think of is only having one set of images for your app.

Android :: Android - Single Top - Launch Mode And OnNewIntent Method

Nov 10, 2009

I read in the Android documentation that by setting my Activity's launchMode property to singleTop OR by adding the FLAG_ACTIVITY_SINGLE_TOP flag to my Intent, that calling startActivity(intent) would reuse a single Activity instance and give me the Intent in the onNewIntent callback. I did both of these things, and onNewIntent never fires and onCreate fires every time. The docs also say that this.getIntent() returns the intent that was first passed to the Activity when it was first created. In onCreate I'm calling getIntent and I'm getting a new one every time (I'm creating the intent object in another activity and adding an extra to it...this extra should be the same every time if it was returning me the same intent object). All this leads me to believe that my activity is not acting like a "single top", and I don't understand why.

To add some background in case I'm simply missing a required step, here's my Activity declaration in the manifest and the code I'm using to launch the activity. The Activity itself doesn't do anything worth mentioning in regards to this:

in AndroidManifest.xml:


in my calling Activity:

Motorola Droid X :: Way To Launch Home Dock Mode While In Car?

Sep 23, 2010

To start, I'll say I've done much searching on my question, both on this forum and others. Plus, I've searched AppBrain using many parameters to no avail.So, that little disclaimer out of the way....I have a DX. My last device was the original Droid. After the upgrade to Froyo on my original Droid, I noticed two really cool and, for me, useful dock functions that do not work with the Froyo upgrade on my DX. Original Droid (w/Froyo): When I would put the Droid in the car dock, there was a nice little icon that said EXIT. Meaning it would go out of car dock completely when you touched it. Even the icon in the top bar would go away. Also, when I hit the home button, say out of Navigation, it would take me to my regular home, vice back to the car dock home. I LOVED this, as I dislike and do not use the car dock mode ever. This icon is non-existent on the Froyo car dock mode on my DX. Next. Again, original Droid (w/Froyo. and I state this because with Eclair, these functions were not there): When plugged in for the night, I would touch my Retro Clock app widget, and (I don't know why, it just did) it would launch the Home Dock screen. (with weather, music icon, etc...) Now this I LOVED also, as I could set my alarm, check the weather where I was at, and even get some news headlines before going to sleep. Plus, it would then go into screen saver mode, dimming the screen nicely. I would like very much to get this kind of functionality back in both instances. Does anyone have any ideas for apps that would kill the car dock mode completely, either permanently, or at least every time I put it in the car dock?And is there some way to launch the home dock mode while in the car dock?I am a truck driver, and the car dock is where I put my X to charge at night.

Motorola Droid :: How To Launch Multimedia Mode Without Dock?

Nov 8, 2009

I bought the car dock and it has served me well thus-far, but I don't really see a reason to plunk down the cash on the home dock. It's nice, but I don't want to buy it right now. However, I do very much like the display that appears when it is docked. I can't find a way to launch this without the dock itself, and I'm certain there has to be a way. What am I missing?

Android :: Applying Style To Textview

Jan 10, 2010

I am trying to apply common style to different textview that can be either defined in a layout xml file or programmatically and that does not seem to work for some attributes: My style in styles.xml is:

<style name="ListName"> <item name="android:colorForeground">#f0f</item> <item name="android:padding">4sp</item> <item name="android:textSize">30sp</item> <item name="android:textColor">#CCC</item> <item name="android:gravity">left</item> <item name="android:typeface">serif</item> <item name="android:textStyle">bold</item> <item name="android:colorBackground">#999</item> </style>

In my layout xml i have <TextView style="@style/ListName" ...></ TextView> and in my activity java class i have: TextView nametv = new TextView(this,null,; However some parameters does not seem to work very well: - textStyle to bolditalic does not seems to be recognized - textColor/colorForeground/colorBackground does not work at all. I have been through the documentation, but could not find precise reference documentation for that attributes, nor sample for the color setting.

Android :: Applying Theme To App Widget

Oct 23, 2010

Android :: Preference Activity And Theme Not Applying

Apr 11, 2010

I have a problem in the Preferences Activity, in the main preferences the theme shows ok, but if I get to a sub preference, the theme gets messy, it is not white as it should, it is all dark, and the font is black so you can't see much, and when I start clicking on any items they will get sometimes white as they should but revert to black soon after. This is only happens on 2.1, in both the real device and emulator. Tested on the emulator running 1.6 and it was working correctly.

Android :: Applying Effects To Camera Viewfinder

Dec 11, 2009

One approach I've looked at is to use the preview callback, asking for a JPEG buffer. Unfortunately, the HTC phones I've tried this on all call back at several second intervals and give me an NV12 buffer regardless of the pixel format you specify. (Anyone know the behaviour on a droid?) I can code my way around the NV12 hassle but I can't exactly do much when the callbacks are so seldom; I want around 10 fps.

The approach I was considering was making an opencore codec for mjpeg. Which leads me to two questions before I start:

1) can third-parties make and install opencore codecs, or is this strictly locked down? Is it to just drop an .so in the right folder, or?

2) do the HTC phones use the default encoders? (i.e. will using the same way the default opencore reference codecs get their pixel buffers work on the phone?)

General :: Android 2.2 - Applying Animation To SurfaceView

Feb 17, 2012

I'm working on a puzzle game for Android 2.2, what I want to do is a simple fade-in fade-out of the whole game screen, during level changing. I tried with an AlphaAnimation from 1.0f to 0.0f and vice-versa, and it works perfectly if I start it from a View, but if I try to start it from the SurfaceView which I used to write my game engine nothing happens.

I put a completely black ImageView on top of my surfaceview, and applied the animation to this imageView. This is my layout

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="<not allowed to post external links...>"

Android :: Best Site For Rooting And Applying Custom ROMs?

Jan 4, 2010

So I am pretty computer savvy but just getting into the phone scene. Wondering what site is best for the hacker side talk of phones?
Androidcommunity vs Androidforums vs XDA dev forums?

Which is better for instructions on rootings and applying custom ROMs?
Which is better for finding ROMs?
Which has more users?
Which has more experts?

Anyone familiar with the other site or one I may not know about can fill me in a bit? I seem to like this site the most but if there is more information elsewhere, I may need to pool my resources. I would prefer for android forums to be my 1 stop shop n go.

HTC EVO 4G :: Increased Resolution To Take Advantage Of Big 4.3 Display?

May 20, 2010

The EVO looks like a sweet phone, and if they ever bring it to Verizon with some LTE love, I'll probably buy one, but does anyone wish that they increased the resolution of the screen just a little to take advantage of that big 4.3" display? Maybe the next gen will. All in all, it looks like a great device, but I don't think it's going to save Sprint from still loosing customers.
