Hello World / New Install

JayKappy — Thu, 29 Dec 2011 19:26:34 GMT

I am trying to install and get a hello world app going...
I wen tthrough the Install instructions which were very confusing, install this before this but after this, but not untill you install this....I have no idea if I installed things right...anyways...

I open Eclipse and go:
File>New>Project
Choose ArcGIS project for Andoid
Give it a project name
Give it a package name (dont really understand this one) I called it "com.esri.andoid.sample"

I keep getting this error in the Console

[2011-12-29 15:11:02 - HelloWorldMap] Unable to resolve target 'android-8'

In the Package Explorer HelloWorldMap, src, com.esri.android.sample, HelloWorldMapActivity.java all have a little red square box next to them with a white X

There are 4 errors in the Problems tab

1. The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project
2. The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files
3. Unable to resolve target 'android-8' HelloWorldMap
4. Unable to resolve target 'android-8' until the SDK is loaded.

Any thoughts? Please help...very confused here....

THanks

I have the same problem, in my case I guess is because the Android SDK 2.2 is not installed and I can't update via SDK manager. Any ideas for this problem?

I have no idea what I did..
I added a new folder in the java build path
I then deleted the folder because it now had errors all over it as well
then I realized that 2 of the 3 errors were gone...
Also noticing that there was now an excluded in the HelloWorldMap/src??????

Why did it do this and how did it resolve most fo the errors....why?????

Whats going on here...this is supposed to be the most simple exampel and that dosent work...I followed verbatum from teh instructions...

ALTHOUGH I STILL HAVE ONE ERROR:
Unable to resolve target 'android-8'

ANYONE know what this error is and how to resolve it??????

JayKappy — Fri, 30 Dec 2011 13:13:09 GMT

Is this telling me that it cannot find the folder containing the Android-sdks?
What is the error pertaining to? I have no idea...

my workspace that was set up is at the same level as the android-sdks...is this why?

C:\Users\jsmith\android-sdks
C:\Users\jsmith\workspace

I got so frustrated that i removed everything I could from my computer and reinstalled Eclipse
Went into Help and "Install New Software"
reintalled the ADT plugin, and set the source
Reinstalled the ArcGIS Android SDK

I then did the following below...

Think I fixed my problems...

1. I think I missed configuring the ADT Plugin

Configuring the ADT Plugin
After you've successfully downloaded the ADT as described above, the next step is to modify your ADT preferences in Eclipse to point to the Android SDK directory:
1.Select Window > Preferences... to open the Preferences panel (Mac OS X: Eclipse > Preferences).
2.Select Android from the left panel.
You may see a dialog asking whether you want to send usage statistics to Google. If so, make your choice and click Proceed. You cannot continue with this procedure until you click Proceed.
3.For the SDK Location in the main panel, click Browse... and locate your downloaded SDK directory.
4.Click Apply, then OK.

2. Right Click project and hit properties. In the android option on the left I had to select the Android 4.0.3 as the project Build Target

3. In the Package Explorer I opened the project.properties and changed the target to target=android-15 instead of target=android-8
a. If you click Help>Preferences adn then the Android tab you will see the API Level...this is where I got the 15 to change in the project.properties file in teh Package Explorer TOC

These have seems to rid the errors....now just need my datacable to test the hello world

It was difficult to tell if you successfully installed the appropriate Android SDK platforms, e.g. 2.2, from your screenshot but I suspect it was not installed when you were experiencing the issues. The fact that you had to select Android 4.0.3 as your project build target and change the target to API level 15 to resolve the issue also implies that you don't have the appropriate Android SDK platforms installed.

You reference that the install instructions were very confusing, which install instructions are you referring to? Are you referring to the ArcGIS instructions or our prerequisite for installing the Android SDK docs which we link to? We really want to ensure the install steps as simple as possible. Currently we do not step you through the Android SDK or ADT install instructions and presume you have this set up before installing the ArcGIS SDK. We have created a blog post which steps readers through the entire process. Please let us know if this helps or if you are continuing to have issues.

You also referenced not understanding the package name. The ArcGIS Runtime for SDK for Android includes a Java API so all source is written in Java. A Java package is a way to organize Java classes into namespaces. This feature make types easier to find and use types and avoids class naming conflicts. Please refer to the Java Package tutorial for reference.

Did you add the HelloWorldMapActivity in the project's AndroidManifest.xml file?

Re: Hello World / New Install

JayKappy — Tue, 03 Jan 2012 15:25:30 GMT

I am confused here....
I right clicked the HelloWorldMap in the Navigator (in eclipse) adn hit properties adn then the Android option in the TOC....I saw API Level was 15
So I manually changed the project.properties target to Target=android-15

Now from yoru example I went into the HelloWorldMap Manifest and saw that it too was referencing android-8...I changed this to Android-15 "<uses-sdk android:minSdkVersion="15" />"

Is my phone out of date? To old of an API? am I readign all fo this correctly and correct to change the settings to 15 instead of 8...I i leave the prpoject.properties at 8 I get an error : unable to resolve android-8

NOW Getting this error:
[2012-01-03 11:15:44 - HellWorldMap] ERROR: Application requires API version 15. Device API version is 8 (Android 2.2).
[2012-01-03 11:15:44 - HellWorldMap] Launch canceled!

HOW DO I KNOW WHAT I SHOUDL BE SETTING THIS AS 8 or 15

I am also gettign errors below on this line: <uses-permission android:name="android.permission.INTERNET" />
Error: <uses-permission> tag appears after a <application> tag

you talking here

<?xml version="1.0" encoding="utf-8"?>

This means that your device has an API level 8.

For this, you need to have API set to 8 in Manifest file, i.e. android:minSdkVersion="8" (which you already have). Also, set the same in the Project Properties => Android tab => Project Build Target - Select Android 2.2 (API Level 😎 instead of API Level 15.

This will do the needful in the project.properties file, which is generated automatically upon building the project. You should not alter this file.

Hope this resolves your issue.

I had the "Unable to resolve target" error along with other random errors.
I fixed it by making the target match the installed platform.
In windows explorer I went to the SDK/platforms directory. In it was a folder named android-19. This indicated I had the android-19 platform installed. I then edited AndroidManifest.xml and project.properties to set the target to android-19.
All errors went away.
