Adjust the log level

You can control the amount of log messages by App Center that show up in LogCat. Use the AppCenter.setLogLevel() API to enable additional logging while debugging. The log levels correspond to the ones defined in android.util.Log. By default, it's set it to ASSERT for non-debuggable applications and WARN for debuggable applications. You can set the log level at any time you want.

To have as many log messages as possible, use Log.Verbose.

AppCenter.setLogLevel(Log.VERBOSE);

AppCenter.setLogLevel(Log.VERBOSE)

Identify installations

The App Center SDK creates a UUID for each device once the app is installed. This identifier remains the same for a device when the app is updated and a new one is generated only when the app is re-installed or the user manually deletes all app data. The following API is useful for debugging purposes.

AppCenter.getInstallId();

AppCenter.getInstallId()

This API is asynchronous, you can read more about that in our App Center Asynchronous APIs guide.

Identify users

The App Center SDK supports setting a user ID that's used to augment crash reports. To use this capability:

1. Configure the App Center SDK by calling AppCenter.start(...) as described in the App Center SDK Getting started guide.
2. Set a userID in the SDK using the following code:

AppCenter.setUserId("your-user-id");

AppCenter.setUserId("your-user-id")

After setting a user ID, you can use App Center's search feature to search for specific crash reports for the ID. Learn more in App Center's search documentation.

Disable all services at runtime

If you want to disable all App Center services at once, use the setEnabled() API. When disabled, the SDK won't forward any information to App Center.

AppCenter.setEnabled(false);

AppCenter.setEnabled(false)

To enable all services at once again, use the same API but pass true as a parameter.

AppCenter.setEnabled(true);

AppCenter.setEnabled(true)

The state is persisted in the device's storage across application launches.

This API is asynchronous, you can read more about that in our App Center Asynchronous APIs guide.

Change state of service in runtime

Enable or disable the services at the runtime with following code:

Analytics.setEnabled(false);

Analytics.setEnabled(false)

Check if App Center is enabled

You can also check if App Center is enabled or not.

AppCenter.isEnabled();

AppCenter.isEnabled()

This API is asynchronous, you can read more about that in our App Center Asynchronous APIs guide.

Check App Center SDK version at runtime

You can get the version of App Center SDK that you're currently using.

AppCenter.getSdkVersion();

AppCenter.getSdkVersion()

Use custom properties

App Center allows you to define custom properties as key value pairs in your app. You may use custom properties for various purposes. For instance, you can use custom properties to segment your users, and then send push notifications to a specific audience.

Set custom properties by calling the setCustomProperties() API. A valid key for custom property should match regular expression pattern ^[a-zA-Z][a-zA-Z0-9]*$. A custom property's value may be one of the following Java types: String, Number, boolean and Date.

CustomProperties properties = new CustomProperties();
properties.set("color", "blue").set("score", 10);
AppCenter.setCustomProperties(properties);

val properties = CustomProperties()
properties.set("color", "blue").set("score", 10)
AppCenter.setCustomProperties(properties)

You may remove any custom property by calling the clear() API. This only removes the value of the property for a device. It won't remove the property name from App Center portal.

CustomProperties properties = new CustomProperties();
properties.clear("score");
AppCenter.setCustomProperties(properties);

val properties = CustomProperties()
properties.clear("score")
AppCenter.setCustomProperties(properties)

Storage size

When using the App Center SDK, logs are stored locally on the device. Large logs can take up a lot of space, so you may choose to limit the size of the local database. It's also useful in conjunction with the pause and resume APIs. If you expect to be paused for a long time, you can use a larger database size to store more events.

You can use the setMaxStorageSize API to set the size of the local DB. The API is asynchronous, and the callback is called when you start App Center services. For this reason, setMaxStorageSize must be called before your call to AppCenter.start(...). You may only call the API once.

// Use 20 MB for storage.
AppCenter.setMaxStorageSize(20 * 1024 * 1024L).thenAccept(new AppCenterConsumer<Boolean>() {

    @Override
    public void accept(Boolean success) {
        // The success parameter is false when the size can't be honored.
    }
});
AppCenter.start("{Your App Secret}", Analytics.class);

// Use 20 MB for storage.
AppCenter.setMaxStorageSize(20 * 1024 * 1024).thenAccept {
    // The success parameter (it) is false when the size can't be honored.
}

AppCenter.start(application, "{Your App Secret}", Analytics::class.java)

If you don't set the max storage size, the SDK uses a default max size of 10 MB. The minimum size you're allowed to set is 20 KB.

Unsuccessful API calls

There are many reasons the callback may fail.

• The specified size is an invalid value (less than 20KB or greater than 140TB).
• The current database size is larger than the specified maximum size.
• The API has already been called. You may configure it only once per process.
• The API has been called after AppCenter.start(...).

You can check warnings and errors in the console using the AppCenter log tag to troubleshoot configuration issues.
