Question

我更新到最新版本的Android Studio和Android SDK后。我不能让它在OS 5以下的设备上运行。我有multidex，应用程序很大。这是问题吗？我将此添加到我的应用程序类的代码中：

 @Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    Log.i("","multidex installed BEFORE");
    MultiDex.install(this);
    Log.i("","multidex installed DONE");
}

有时它起作用，有时它不起作用。我很多次都这样做，这是一个错误：

有时它确实设法加载应用程序类，但后来我收到的错误是它无法识别googlemaps或Fabric或其他，例如：

我猜测在MultiDex.install完成之前它会到达代码，这就是它崩溃的原因吗？我对吗？如果是的话，如何解决这个问题？
