Android :: Stay Backwards And Forwards Compatible - TargetSDKVersion Hdpi MinSDKVersion?
Apr 16, 2010Here's my situation: I have an app that's been compiled using 1.5 SDK and minSdkVersion=3. Now I want to add 2 icons: one for high density screens like Droid and another one for low density screens like G1.
For this, I added the high density icon to new directory drawable-hdpi- v4/. I then compiled using 1.6 sdk and added targetSdkVersion="4" to the manifest. minSdkVersion is still 3.
This is working in limited testing, but I'm not sure if I have done everything correctly.
I have many questions:
1. By specifying v4 in drawable-hdpi-v4, the icon will not be displayed to 1.5 or below OS's. But what about users with 2.0 or higher SDK's? Will they get the non-hdpi icon, since they will have v6 or v7 ?
2. The documentation for targetSdkVersion states, "Specifying this target version allows the platform to disable compatibility settings that are not required for the target version (which may otherwise be turned on in order to maintain forward-compatibility)". Does this mean that my app will not be forward compatible as soon as I specify a targetSdkVersion? What exactly is being turned off?
3. Even if I leave out the targetSdkVersion="4", the app runs ok. So do I really need it?
4. Should I be using the latest SDK (2.1) and setting that as the targetsdkversion and compiling against that? Or some other combination of targetsdkversion and compiling sdk? I'm not using any API's that are not in 1.5..
5. Is any of this related to why some of my HTC Eris users have complained that they can no longer find my app in Market after upgrading to 2.1?
Android :: Using TargetSdkVersion? Should Support Full Resolution And Not Emulate A Lower Resolution Screen
Jun 26, 2010I have a program that should work on Android 1.5, but when it's run on newer devices with higher resolution screens, it should support the full resolution and not emulate a lower resolution screen. As far as I can tell from the documentation, this should be simple.
I just specify
code:.........
The problem is that if I tell Eclipse to compile for 1.5, it refuses to accept this. It reports an error (targetSdkVersion is an unknown tag) and refuses to compile or run. If I tell it to compile for 1.6 it works fine, of course. But if I then try to install on a 1.5 AVD, the program immediately crashes with a java.lang.VerifyError. I'm clearly missing something simple. How do I get it to compile an apk that works under 1.5, but still includes the targetSdkVersion tag?

View 1 Replies View RelatedAndroid :: TargetSdkVersion - 8
Nov 24, 2010My Android application uses minSdkVersion=3 and targetSdkVersion=8. I used 8 because that is the highest level of API the application was tested on; however, it was written for level 3 and does not use any features beyond that level (except one for level 4 using reflection). Could using targetSdkVersion=8 be causing: the Android Market to filter the application for some devices? My intention is for the application to be available for ALL devices >= level 3 with NO filtering. problems in the application since targetSdkVersion=8 will, according to google: "disable compatibility settings that are not required for the target version (which may otherwise be turned on in order to maintain forward-compatibility) or enable newer features that are not available to older applications".
View 1 Replies View RelatedAndroid :: What Does TargetSdkVersion Do
Jan 5, 2010What does targetSdkVersion do?
There isn't much detail on what targetSdkVersion actually does.
I've read:[url]
An integer designating the API Level that the application is targetting.
With this attribute set, the application says that it is able to run on older versions (down to minSdkVersion), but was explicitly tested to work with the version specified here. Specifying this target version allows the platform to disable compatibility settings that are not required for the target version (which may otherwise be turned on in order to maintain forward-compatibility) or enable newer features that are not available to older applications. This does not mean that you can program different features for different versions of the platform—it simply informs the platform that you have tested against the target version and the platform should not perform any extra work to maintain forward-compatibility with the target version.
Introduced in: API Level 4
I'm curious because it appears that switching from:
<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"/> to <uses-sdk android:minSdkVersion="3"/> is the change that started the
android.view.InflateException ... java.lang.OutOfMemoryError: bitmap size exceeds VM budget
errors I was randomly seeing in setContentView. When I remove the targetSdkVersion it runs much better.
Now I'm having trouble remembering what adding targetSdkVersion got me in the first place.
Android :: Retrive Different Icon When App Targets MinSdkVersion 3 And 4
May 30, 2010My application retrieve icons of installed apps on the phone. But for the dialer, the icon is different when I target a minSdkVersion = 3 or minSdkVersion = 4. I did not found different icon for an other application.
I am testing on a motorola milestone. and I use ActivityInfo.loadIcon() to load icons.
Can someone explain this behavior ?
Android :: ListView Focus Behaving Different When Using MinSdkVersion-3
Mar 15, 2010A few days ago I was trying to fix this issue: I have a header (three ImageButton's) and a ListView. If I use the dpad, pressing DOWN to focus the ListView, the ListView shows as selected the seventh or eighth row, not the first one.
What I need to do is that the first element of the ListView get the focus (or selection) when I use the dpad, from another screen component, but instead, the seventh or eighth is selected.
I had minSdkVersion=3 in my manifest. When I changed it to minSdkVersion=4 it worked as expected (first row selected). Don't know why, but there is a difference between both.
Android :: Not Able To Use New Resource Identifiers With TargetSdkVersion Defined In Manifest?
Jul 9, 2010I'm developing an Android application that I'd like to be compatible with 1.5 (SDK version 4).
I'm testing the application on 2.2 (SDK version 8).
To do this, I'm including in the manifest file the line <uses-sdk android:minSdkVersion="4" android:targetSdkVersion="8" />
I thought this would allow me to use the newest manifest elements and APIs, but I'm getting a compile error whenever I try to use them. For example, I try to define the element installLocation to allow the app to be installed on the SD card, but Eclipse gives me the error
No resource identifier found for attribute 'installLocation' in package 'android'
Is there something else I have to do to get this to work? If I can't get this to work, what benefit is defining targetSdkVersion?
Android :: Can't Upload .apk To The Market - MinSdkVersion Error Every Time
Apr 27, 2010I wrote a basic soundboard app, and it runs fine there's nothing wrong with it. I want to upload it to the Market, but every time I try I get an error message:
Market requires the minSdkVersion to be set to a positive 32-bit integer in AndroidManifest.xml
That is already in there, I'm using 1.5 so I have my minSdkVersion set at 3. I don't understand what the problem is, and I've asked a lot of devs that never know what to tell me. I don't want to use a different platform because my phone currently uses 1.5. Others have suggested putting the <uses-sdk> line under the <manifest> line, but that hasn't helped at all.
Here is what my manifest looks like:

Android :: Android - Manifest TargetSdkVersion Change - Icon Not Visible - Widget No Longer Works - Cannot Access Data
Mar 20, 2010I recently upgraded my Android app to support multiple resolutions. Previously, my Android.manifest file had a line:
To support multiple density and resolution devices, I changed this to:
CODE:............
I then added a couple of new directories, like drawable-hdpi-v4 and drawable-long-hdpi-v4 that includes the high-res versions of the graphics. That's about it.
Ever since releasing this update, there have been a decent number of users complaining about various problems:
the app icon doesn't appear (I did not create a high res version of the icon)
the home screen widget no longer works, even if they delete and re-add it (this code did not change with the update). I've had a user send me their error log, which shows:
CODE:................
There is one questionable section in my existing widget code that may be relevant:
CODE:..........
And perhaps most troublesome: the sqlite database is no longer accessible/writeable for some users so their data is no longer available. I did add the WRITE_EXTERNAL_STORAGE permission to the manifest. This is only happening to certain users and it tends to be HTC Eris users. In that error log I see things such as:
CODE:.........
It's as if the update has caused a new process and it can't access the old process's data, or something.
Android :: Can't Upload App In The Market - Market Requires The MinSdkVersion To Be Set In AndroidManifest.xml

View 2 Replies View RelatedAndroid :: Way To Check API Compatibility Of App For Lower Levels?
Oct 8, 2010I'm developing an Android app which will target 2.1/2.2 devices, so I have my project set up to use the 2.2 SDK (API level 8), but allow for installation on devices with at least API level 7. The problem is that during my daily development, I'm not always paying close attention to which API level of the methods/classes/constants that I'm using, which makes it very easy to break code on older devices. I have got dynamic classloading working, and as much as I dislike having a ton of extra factory classes and interfaces in my project, I'm willing to deal with that solution. Currently, the only way I have to check an older API level is to set my project's settings to the given level, rebuild, see what breaks, and then refactor. It's quite a pain. What I would really like is the ability to scan my code and check compatibility for a given API level without changing my global project build settings. Is there some easy way to do this?

Jun 30, 2010I am thinking about getting a tablet instead of a netbook (Eken M001 has 1.6) which i need for mostly working out my routes in the morning since I work for a delivery company. Right now I have to come home to use autoroute on my PC but this takes me an hour to get home and back again taking an hour out of my journey so a tablet would be a perfect alternative. I live in the UK so need an autorouter for me that works offline. Does any such app exist or should I get a netbook?
Basically I just need to enter a bunch of postcodes and it tell me the quickest order in which to goto them to save time in my day but going home to get them is kinda against the whole point of saving time.

Is this a problem with something I'm doing or does viewing twitter use battery faster then it can charge?

General :: Run Apps At Lower Resolution?
Jan 28, 2013In general,can we change some properties to make a given app run on a lower than native resolution?I think it should be totally possible,since phone come in various aspect ratios and resolutions.So the app detects the screen and resolution,and adopts accordingly.Gensoid does that in-app.Double,original size,strech,etc....
For instance,if we have a game on a 1920x1080 screen,but the GPU struggles to keep the framerate,we lower it to 960x540,the game still looks fine,because we get 1:2 resolution,and far fewer pixels to push.I think there should be an app for that.
