GetIdeas example - ApiException not instance of Throwable?

[p9g...@gmail.com]

Hi all,

I have a compilation problem while trying to execute this example https://github.com/googleads/googleads-java-lib/blob/master/examples/adwords_axis/src/main/java/adwords/axis/v201502/optimization/GetKeywordIdeas.java

The line 118

TargetingIdeaPage page = targetingIdeaService.get(selector);

gives me this error

Unhandled exception type ApiException

If I try to add this in the method declaration (even if there is already throws Exception ) it tells me

No exception of type ApiException can be thrown; an exception type must be a subclass of Throwable

Also, in the example there is no import of the ApiException class, so I added

import com.google.api.ads.adwords.axis.v201502.cm.ApiException;

Any help is really appreciated! Thank you in advance.

Hi,

That error suggests that your classpath is not configured correctly. Please check out the section of our README on configuring dependencies and let me know if you still have questions.

Thanks,

Josh,

I'm having the issue as OP.  I have tried troubleshooting my classpath, but have been unsuccessful.  I am using Android Studio and the line I am using which generates an unhandled exception is straight from the GetCampaigns.java sample code:

"page = campaignService.get(selector);"

I am stuck and any further help or suggestions is greatly appreciated.  I am also curious to how the OP solved their problem.  

Thank you in advance.

Hello,

I'll try to answer, hoping to remember correctly from one year ago.

As for me, it was a problem of importing packages. I was trying to import only a subset of the packages in adwords.axis.(etc.) to create a smaller project.

When I included the whole jar. (with all sub-jar), it worked.

I hope you can solve your issue,

Kind regards

Pietro

Hello Josh

I know you answered this a while ago but I have the same problem. I've read https://docs.oracle.com/javase/8/docs/technotes/tools/windows/classpath.html and even if this page explains
what a classpath is, it was not written for Google AdWords API. So what do I need to do regarding this classpath issue? What file(s)? I also sit with Android Studio.

Kind regards
Richard

Hi Richard,

Could you share the error you're getting from the compiler? I want to make sure this is the same issue as mentioned below, so it would be helpful to have more details for your particular case.

Thanks,

Hi Josh

Thank you for your time! :)

Code and errors are as follows:

try {
    adWordsHandler = new AdWordsHandler(context);
    adWordsHandler.callAdWordsAPI();
    sales = adWordsHandler.getEntries();
    resourceHandler.addResources(Sale.class.getName(), sales);
} catch (RemoteException e) {
    e.printStackTrace();
} catch (ApiException e) {
    e.printStackTrace();
} catch (Exception e) {
    e.printStackTrace();
}

public void callAdWordsAPI() throws Exception, ApiException {
...
AdGroupAdPage entries = adService.get(selector);
...
}

Error:(104, 9) error: cannot access RemoteException
class file for java.rmi.RemoteException not found

Error:(61, 52) error: incompatible types: ApiException cannot be converted to Throwable

Error:(89, 46) error: cannot access Remote
class file for java.rmi.Remote not found

Take care! :)

Kind regards
Richard

Hi Richard,

Thanks - that definitely helps! Could you let me know how you're managing your dependencies? For example, are you using Maven, Gradle, or just setting your classpath manually (e.g., by copying dependencies to a lib folder)?

I ask because the error that java.rmi.RemoteException is not in your classpath indicates that you are missing some key dependencies. If it helps, you can see the list of dependencies to add for Maven here in the README. If you aren't using Maven, you can download the adwords-axis-jars-and-examples archive on the releases page, which contains a lib folder with all required dependencies.

Thanks,

Hi Josh

As I currently sit with Android Studio/Gradle, I would prefer continuing using these, I can skip Gradle for the next project but for now I would like to learn how to solve this Gradle issue.

Oh, by placing the files under the libs folder you set the classpath(s) manually?

The part about the archive I have done already (my other forum post with Dhanya Sundararaju (AdWords API Team) as he suggested the same). But that does not solve the issue I got
as a result of this inclusion of jar files.

Thank you for your time! :)

Kind regards
Richard

[Josh Radcliff (AdWords API Team)]

Hi Richard,

Would you mind sharing your Gradle config so I can see how you're bringing in the library dependencies? Also, just to rule certain things out, could you let me know which version of Java you're using?

Thanks,

Hi Josh

According to the controlpanel I have Java 8 Update 162.

build.gradle under app folder:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    defaultConfig {
        applicationId "yada.yada"
        minSdkVersion 23
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    jcenter()
    google()
}


dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:design:26.0.2'
    implementation 'com.android.support:appcompat-v7:26.0.2'
    implementation 'com.google.android.gms:play-services-maps:11.8.0'
    //implementation 'com.google.api-ads:ads-lib:3.10.0'
    //implementation 'com.google.api-ads:adwords-axis:1.38.0'

    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
}

Thank you for your time! :)

Kind regards

Hi Richard,

Thanks for sending over that info. I noticed two things about your dependencies section:

1. The dependencies for the Google Ads APIs Client Library for Java are commented out:

    //implementation 'com.google.api-ads:ads-lib:3.10.0'

    //implementation 'com.google.api-ads:adwords-axis:1.38.0'

Was that intentional, and was that the state of the config when you tried to run the example? With those two lines commented out, none of the library's classes will be on the classpath.

2. The versions specified for the two Google Ads APIs Client Library for Java do not match. For example, if you're using 3.10.0 for ads-lib, you should also use 3.10.0 for adwords-axis. Although Maven requires separate versions for each dependency, in practice we always keep all of our Maven artifacts on the same version. The latest version for the library is 3.12.0.

Thanks,

Josh, AdWords API Team

Hi Josh

1) Yes, it is intentional as I first believed that by placing the jar files under the libs folder that they would get their respective classpath automatically.

2) I've updated the build file as follows:

implementation 'com.google.api-ads:ads-lib:3.12.0'
implementation 'com.google.api-ads:adwords-axis:3.12.0'

I still have the RemoteException problem..

Kind regards
Richard

[Josh Radcliff (AdWords API Team)]

Hi Richard,

My knowledge of Gradle is pretty limited, I'm afraid, but did you try adding mavenCentral() to your list of repositories as shown here?

Thanks,

Josh, AdWords API Team

[goldenmaza]

Hi Josh

Wasn't jcenter replacing mavenCentral?

But why do I still get RemoteException and why is the ApiException still a problem (underlined red and something about Throwable)?

Kind regards
Richard

[Josh Radcliff (AdWords API Team)]

Hi Richard,

This StackOverflow post suggests that RMI may not be packaged with Android. Are you developing an Android application, or are you just using Android Developer Studio as your IDE?

Regarding jCenter, you're absolutely correct. :)

Thanks,

Josh, AdWords API Team

Hi Josh

Wonderful, that would set me back alittle...

Yes, I'm using Android Studio for my first Android app. It uses not only Google AdWords API but also Google Maps API. I felt like Android Studio would
be a good starting point. Do I need to get Eclipse with Maven just for AdWords and develop everything else in Android Studio? Currently, my problem to make
my code run is this ApiException class that seem to need RemoteException. If there is no default way of getting RMI for Android Studio, then I don't have
much options left.

Why is it needed for ApiException with AdWords?

Kind regards
Richard

[Josh Radcliff (AdWords API Team)]

Hi Richard,

The RMI package is needed because the objects generated for the Axis SOAP toolkit are all based on that package. For example, ApiException in the library ultimately extends java.rmi.RemoteException via the inheritance hierarchy of ApiException -> ApplicationException -> AxisFault -> RemoteException.

One thing you could try would be to use the JAX-WS (AppEngine) modules instead of the Axis modules. Those would be:

    <dependency>

      <groupId>com.google.api-ads</groupId>

      <artifactId>ads-lib</artifactId>

      <version>RELEASE</version>

    </dependency>

    <dependency>

      <groupId>com.google.api-ads</groupId>

      <artifactId>adwords-appengine</artifactId>

      <version>RELEASE</version>

    </dependency>

I suspect you'll run into similar RMI dependencies there, but it's worth a shot. :)

Cheers,

Hi Josh

By having the following in the build.gradle file:

implementation 'com.google.api-ads:ads-lib:3.12.0'
implementation 'com.google.api-ads:adwords-axis:3.12.0'

implementation 'com.google.api-ads:adwords-appengine:3.12.0'

I get the classpath errors:

Error:Unable to resolve dependency for ':app@release/compileClasspath': Could not resolve com.google.api-ads:adwords-appengine:3.12.0.

I even have the adwords-appengine-3.12.0.jar file under the app/libs folder...

I have even invalided cache and done a restart, no luck...

I miss the day of front-end development where I didn't have these problems...

Kind regards

Richard

[Josh Radcliff (AdWords API Team)]

Hi Richard,

Could you try removing the line for adwords-axis? The idea is that you'll either use adwords-axis or adwords-appengine, but not both.

Thanks,

Josh, AdWords API Team

[goldenmaza]

Hi Josh

I tried both, no change. I'm trying to configure Eclipse to use my old project files but the problems with dependencies are even worse in this

environment. There is no convert project from Gradle/Android to Maven/Eclipse functionality in Eclipse?

Kind regards

Richard

[Josh Radcliff (AdWords API Team)]

Hi,

The Gradle Maven Plugin will generate a pom.xml for your project based on your Gradle configuration. Could you give that a try?

Another option is to use a Gradle plugin for Eclipse, such as Eclipse Buildship.

Thanks,
