Question

问题是我有一个代码，其中我现在已经扩展应用程序类来解决我使用继承的问题，但即便如此我的应用程序崩溃。

我的android清单代码是

public class AnalyticsApplication extends Application {
private Tracker mTracker;


/**
 * Gets the default {@link Tracker} for this {@link Application}.
 * @return tracker
 */
synchronized public Tracker getDefaultTracker() {
    if (mTracker == null) {
        GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
        //To remove on publish
        if (BuildConfig.DEBUG) {
            // do something for a debug build
            analytics.setDryRun(true);
        }

        // To enable debug logging use: adb shell setprop log.tag.GAv4 DEBUG
        mTracker = analytics.newTracker(R.xml.global_tracker);
    }
    return mTracker;
}

Answer 1

尝试将android:name更改为"com.youth4work.ibps.PrepApplication"

无法将Google分析与其他类扩展应用程序类一起使用？
