B) The advertisement should be placed where the user can see
C) The advertisement must not overlay useful content
D) The advertisement should not be next to UI inputs.

Accepted Answer

B) The advertisement should be placed where the user can see is important because if the user cannot see the ad, it is less likely to be effective.
C) The advertisement must not overlay useful content because if the ad covers up important information, it can be frustrating for the user and make them less likely to engage with the app or the ad.
D) The advertisement should not be next to UI inputs because if the ad is too close to buttons or other interactive elements, it increases the likelihood of accidental clicks, which can be frustrating for users and diminish the effectiveness of the ad.

To enable AdMob ads, the application's manifest file should have the required permissions and include the activity com.google.ads.AdActivity. The permission android.permission.INTERNET is necessary to allow the application to access the internet and load the ads, but it alone is not sufficient to enable AdMob ads. Additionally, there is no need to add a service tag or a receiver tag for AdMob ads.

A) Testing and debugging an application.
B) Monetizing an application.
C) Publishing an application.
D) Choosing the method of distribution.

The last step in the application development process for a specific version of an application is publishing the application. This involves making the application available for users to download and use on their devices through various app stores such as Google Play, Apple App Store, or Microsoft Store. Monetizing an application and choosing the method of distribution can come before or after publishing, depending on the developer's goals and preferences. Testing and debugging an application is an important step, but it is not necessarily the last step as it may need to be repeated throughout the development process.

D) To let the paid application start downloading APK expansion files if your application needs them.

Question 10

Which of the following is a correct step for getting a license key from Google Play?
A) Create an application draft on Google Play then upload the APK file without publishing.
B) Create an application draft on Google Play then upload the APK file and publish it.
C) Upload the APK file without publishing and save it as a draft then.
D) Upload the APK file, publish it, and then save it as a draft.

Accepted Answer

To get a license key from Google Play, it is recommended to create an application draft on Google Play and upload the APK file without publishing. This allows for testing and evaluation of the application before it is made available to the public. Once the APK file is uploaded, the License Key can be generated and used for authentication purposes. Uploading and publishing the APK file may result in the application being publicly available before it has been fully tested and evaluated.

Question 11

How do you avoid requesting invalid impressions in an application's ad?
A) Request a test ad - which is always available.
B) Create object AdTestRequest of Google Ads SDK.
C) Load a an HTML file saved in a testing device
D) Remove the android.persmission.INTERNET permission.

Requesting a test ad is the best way to avoid requesting invalid impressions in an application's ad. Test ads are always available and do not count towards the app's actual ad impressions. Additionally, creating object AdTestRequest and loading an HTML file are not effective ways to avoid requesting invalid impressions. Removing the android.permission.INTERNET permission would prevent the app from accessing the internet altogether, which is not a solution to this specific problem.

A) Use the import statement.
B) Use the package statement.
C) Add an external JAR from the project properties.
D) Set the project's Java compiler to the latest version.

Accepted Answer

To add a library to a project's build path in Eclipse, you can add an external JAR from the project properties. This allows the project to access any classes or resources contained within the library. The import statement and package statement are used to specify which classes are being used in the code, but do not directly add a library to the build path. Setting the project's Java compiler to the latest version may improve performance and allow access to newer language features, but does not affect the build path.
