android target 16 needed when 18, 15, and 8 already downloaded? - android

I have imported a project with these settings :
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="15" />
and I had already downloaded the packages 18 , 15 and 8.
There is an error saying : "unable to resolve target 16" , would you know why? Is there somewhere else an option that would say "API 16 needed" ? And isn't it enough to have already the 3 packages ?
Thanks

There is an error saying : "unable to resolve target 16" , would you know why?
The build target of the project (e.g., Project > Properties > Android) was set to API Level 16. Eclipse should have automatically changed it to 18, given your described setup (first available higher SDK).

android:navigationBarDividerColor requires API level 28

Previously, I implemented light and dark navigation bar, however now tags as android:navigationBarDividerColor and android:windowLightNavigationBar require API level 28 when they previously required API level 27.
It seems API level 28 does not even exist as next API level is called P.
Is there any solution to this problem? Thanks in advance.
UPDATE: it seems to work now on API 27 with latest support libraries
When the "next upcoming API" is still under development, its "name" is a letter (P in your case).
Once the final version of the API is available, the "name" is changed form a letter to a number (P to 28).
Final version of Android API 28 (former Android P) is available since early June 2018. Just use the SDK manager and you'll be able to download it ;-)
Note:
Sources for "Android SDK Platform xx" (28 in your case)" is not available right away. (not available ATTOW)It can takes a few weeks before they are available for download from the SDK manager.
Today I've updated compileSdkVersion, targetSdkVersion and buildToolsVersionfrom 27 to 28. Now I'm facing the same issue as #Teďourek described.
While it was working for me on 27, since the upgrade I now get lint errors:
Error: android:navigationBarDividerColor requires API level 28 (current min is 19)
Error: windowLightNavigationBar requires API level 28 (current min is 19)
This is strange because according to the docs for both attributes it says:
"added in API Level 27"
My temporary fix is to move the two style attributes to v28/styles.xml instead of v27/styles.xml
Since I would like to use lightNavBar + color also on Android 8.1.0 as previously, I would be happy if anyone knows a fix!
With compileSdkVersion and targetSdkVersion set to 29 it seems to be correct.
The XML properties tell me it was added in API level 27.
Only the Java Window properties are added in API level 28.

API target and min confusion

I am confused about the target build and sdk usage
Lets say I have this code
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
//do xyz
}
Let say that I built against API 19 (kitkat) and my target api in manifest is 19 and my minimum supported api is 9
Now if a device with API 9 runs the above code, will it crash? I expect the answer is yes becasuse it will not understand what Build.VERSION_CODES.KITKAT means. However, what's the point of the check above then in first place?
Please help clarify this
Thank you
It won't crash. Simply the code within the if won't be executed. Build.VERSION_CODES.KITKAT is a constant field, and as you can read here, the constant fields are replaced with the numbers themselves by the compiler.
lesser versions of android will use the support library, if the check for kit-kat fails, it will revert to the closest possibkle form that version supports.... via the support library...
you cannot run you app on anything less than the minimum version, but it will find a way to run with less than the target version as long as its aboe the minimum
No, it won't crash, because its Build.VERSION.SDK_INT value is 9. It simply will not enter inside your if clause. Only devices that have API version 19 or above will run your code inside the if. Build.VERSION_CODES.KITKAT is equal to 19.
The code you posted won't crash because the class Build is created and compiled for every build of your app (as the R file) depending of the target API you set in the manifest
As you setup your target API to 19, the Build class will contain the field Build.VERSION_CODES.KITKAT because it exists starting from API level 19.

Android SDK Check Not Working

I am trying to change the transition from default to sliding in. I would like to keep my minSdkVersion to be 3 however overridePendingTransition wasn't added until API level 5 (Android 2.0).
I tried creating an integer to represent the SDK version and then only override the transition when in Android 1.6 or less via a simple if statement.
int sdkVersion = Integer.parseInt(Build.VERSION.SDK);
if(sdkVersion>=5)
overridePendingTransition(android.R.anim.slide_in_left, android.R.anim.fade_out);
Eclipse gives me a LINT warning stating "Call requires API level 5 (current min is 3): android.app.Activity#overridePendingTransition"
If I suppress this error and run it anyway it crashes on Android 1.6 or lower.
What is wrong with my code and how can I fix it? Any suggestions would be very appreciated!
In your android manifest file you have this ...
<uses-sdk
android:minSdkVersion="3"
android:targetSdkVersion="latest version" />
Change the min sdk version to 5 like show below
<uses-sdk
android:minSdkVersion="5"
android:targetSdkVersion="latest version" />

'parse error' when trying to install apk on devices below minimum sdk

When I try to install apk on devices whose sdk level is less than what is mentioned in manifest, I get Parse error message. My question is, is there a way through which we can show a custom message to the user? For example: this app requires min android version to be ICS or something like that.
<uses-sdk
android:minSdkVersion="8" />
Just put it in your androidmanifest.xml file
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="16" />
then inside onCreate you can check the sdk version as bellow:
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
and show a dialog telling the user that this app requires min android version to be ICS
then finish the application !

getting force close while running the android application

While running my application i am getting the below given warning and application went force close.
[2011-10-17 12:09:09 - LunarLander] WARNING: Application does not specify an API level requirement!
[2011-10-17 12:09:09 - LunarLander] Device API version is 9 (Android 2.3.1)
How to resolve this. I created another emulator with API level 10, then also i am getting the same error.
I am sure you forget to define the API level inside the AndroidManifest.xml file, define it as:
<uses-sdk android:minSdkVersion="5"
android:maxSdkVersion="10"
android:targetSdkVersion="8"/>
You should define the API level of your application in manifest file. I think you forgot to that. Launch the application according to that.
Just looking at that error you need to specify an API level for your application:
