我更新了我的 Android 应用的代码以包括:
- 活跃的安卓
- TargetsdkVersion 22(布局中包含一些 Material Design 元素)
- MinSdkVersion 9(这也是我的早期版本)
- Google Analytics v4，Google Play 服务的一部分
我的早期版本是在 Eclipse 中创建的，这次更新我使用的是 Android Studio。导入没有用，所以我在 Android studio 中重新创建了项目。对于主要部分，它似乎工作正常。
但是当应用程序第一次启动时，它很慢。在主屏幕显示之前，盯着白色屏幕大约需要 1.5 秒。之后，该应用程序运行良好且快速。
重新启动它，当将应用程序保存在内存中时，它会立即启动。如果您将应用程序从内存中取出，它还需要 1.5 秒(/2 秒)才能开始。
我在 Nexus 7 (2013) 和 FairPhone (Android 4.2.2) 上对其进行了测试。我不明白问题出在哪里，也许你可以帮助我。一个解决方案会很好，但即使指出原因也会有很大帮助。
App.java(扩展Application)相关代码:
@Override
public void onCreate() {
super.onCreate();
mContext = this;
Log.v("App","onCreate App - before GoogleAnalytics.getInstance(this)");
analytics = GoogleAnalytics.getInstance(this);
analytics.setLocalDispatchPeriod(1800); // every 30 minutes
tracker = analytics.newTracker("REMOVED CODE FOR STACKOVERLOW");
tracker.enableExceptionReporting(true);
// Since I do this 'by hand', enabling automatic will amount to double counting.
tracker.enableAutoActivityTracking(false);
Log.v("App", "onCreate App - after GA");
// Because it is initialized here, we don't need to put it as the application in Manifest
// This means we can use Google Analytics code referring to 'getApplication'.
ActiveAndroid.initialize(this);
Log.v("App", "onCreate App - after AA");

Google Analytics 出了点问题，但这并不是导致应用启动速度变慢的主要原因。主要问题似乎是像这样的行:
Unable to resolve superclass of Landroid/support/v4/app/ActivityCompat21$SharedElementCallbackImpl; (54)
我不知道如何解决这些问题，因为其他带有此类日志消息的 StackOverflow 帖子假定它与 .jar 库有关并且在 Eclipse 上。
喜欢这里: Android - Unable to resolve superclass 两者都不适用于我的问题(据我了解)。
在 Nexus 7 (2013) 上，应用程序的启动也很慢，但日志文件给出了不同的读数:

虽然大部分内容我都没有完全理解，但我认为这是最奇怪的一行:
Before Android 4.1, method int android.support.v7.internal.widget.ListViewCompat.lookForSelectablePosition(int, boolean) would have incorrectly overridden the package-private method in android.widget.ListView
如果有帮助， list 文件的开头:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.juliushuijnk.tools.ideagrowr"
android:installLocation="auto" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application

android:allowBackup="true"

android:label="@string/app_name"

进一步的背景:我不是专业的软件开发人员，这是一个宠物项目。学习如何解决这样的问题也很棒。
最佳答案
我自己想通了。所以最后，这是由于我如何实现 ActiveAndroid 库。
除非您使用有助于 AA 快速找到模型的配置，否则它只会让您的应用启动非常慢。
我用这段代码修复了它: How to disable scanning for model in Activeandroid
这样的代码(但我有不同的型号名称):
Configuration.Builder configurationBuilder = new Configuration.Builder(this);
configurationBuilder.addModelClasses(Test.class);
configurationBuilder.addModelClasses(ShoppingList.class);
configurationBuilder.addModelClasses(ShoppingListItem.class);
configurationBuilder.addModelClasses(ArticleInfoModel.class);
ActiveAndroid.initialize(configurationBuilder.create());
现在几乎是即时启动。我仍然不确定为什么我会收到所有这些奇怪的 logcat 条目。所有“无法解析父类(super class)”可能是 AA 在没有配置的情况下如何运行的某种间接产物。自从我添加配置后，这些行现在消失了。
这些 logcat 行让我在寻找与 gradle 和支持库有关的答案时感到困惑，但这不是问题的根源。
所以我应该从一开始就实现该配置。但它在 AA 的写作方式让人感觉“拥有它很高兴”。

所以我了解到，下次当我看到一些我认为“很高兴拥有”的东西时，我应该在评论中写下我的假设，这样我就可以在遇到问题时快速了解我可能需要更改的地方。 .
