Question

我想在我的应用程序中使用 Analytics ，我会在下面编写代码，但是当用户点击我的应用程序中的注销和注销时，请显示我强行关闭错误！

AnalyticsTrackers代码：

public final class AnalyticsTrackers {

    private static AnalyticsTrackers sInstance;
    private final Context mContext;

    /**
     * Don't instantiate directly - use {@link #getInstance()} instead.
     */
    private AnalyticsTrackers(Context context) {
        mContext = context.getApplicationContext();
    }

    public static synchronized void initialize(Context context) {
        if (sInstance != null) {
            throw new IllegalStateException("Extra call to initialize analytics trackers");
        }

        sInstance = new AnalyticsTrackers(context);
    }

    public static synchronized AnalyticsTrackers getInstance() {
        if (sInstance == null) {
            throw new IllegalStateException("Call initialize() before newInstance()");
        }

        return sInstance;
    }


    public enum Target {
        APP,
        // Add more trackers here if you need, and update the code in #get(Target) below
    }
}

我的应用代码：

public class MyApplication extends Application {
    private static final String TAG = "MyApplication";
    // The following line should be changed to include the correct property id.
    private static Context mContext;

    public static Context getContext() {
        return mContext;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        MultiDex.install(this);
        mContext = getApplicationContext();
        if (Utils.checkPlayServices(mContext) && Utils.skipLogin(mContext)) {
            // Start IntentService to register this application with GCM.
            Intent intent = new Intent(this, RegistrationIntentService.class);
            startService(intent);
        }
        Fabric.with(this, new Crashlytics());
        AnalyticsTrackers.initialize(mContext);
        FileDownloader.init(mContext);
        }

    }

    @Override
    protected void attachBaseContext(Context base) {
        try {
            super.attachBaseContext(base);
        } catch (RuntimeException e) {
            e.printStackTrace();
        }
//      MultiDex.install(this);
    }
}

logcat错误：

我该如何解决这个问题？谢谢所有＆lt; 3

我还面临由AnalyticsTracker.java中的IllegalStateException引起的同一问题。我能够通过在AnalyticsTracker.java中进行一些修改来解决问题。这是修改。

替换initiliaze（）方法的代码

if (sInstance != null) {
            throw new IllegalStateException("Extra call to initialize analytics trackers");
        }

        sInstance = new AnalyticsTrackers(context);

带

if (sInstance == null) {
            sInstance = new AnalyticsTrackers(context);
        }

通过此修改，您将停止抛出异常并防止重复实例初始化。
