自定义Application生命周期

自定义Application代码如下

public class MyApplication extends Application {

    private static Context sContext;
    private static final String TAG = MyApplication.class.getSimpleName();


    static {
        Log.e(TAG, "static");
    }

    @Override
    public void onCreate() {
        super.onCreate();

        Log.e(TAG, "onCreate");

        initialize(this);
    }

    public static void initialize(final Context context) {

        Log.e(TAG, "initialize");

        sContext = context;
    }

    public static Context getContext() {

        Log.e(TAG, "getContext");


        return sContext;
    }

    public MyApplication() {

        Log.e(TAG, "MyApplication");

        sContext = this;
        if (sContext == null) {
            Log.e("JinLib", "JinLib is not initialize");
            return;
        }
        init();
    }

    private void init() {

        Log.e(TAG, "init");

    }

}

当在正常的 Activity中调用，执行顺序如下
