Android应用启动缓慢，但在缓慢启动后工作正常
我更新了我的Android应用程序的代码，包括：
- ActiveAndroid
- TargetsdkVersion 22（现在布局中有一些Material Design元素）
- MinSdkVersion 9（这也是我早期的版本）
- Google Analytics v4，Google Play服务的一部分
我的早期版本是在Eclipse中创建的，此更新我正在使用Android Studio。 导入无效，因此我在Android studio中重新创建了该项目。 而对于主要部分，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，需要大约1.5秒的时间盯着白色屏幕。 之后，该应用程序运行良好，快速。
重新启动它，将应用程序保留在内存中时立即启动。 如果您将应用程序从内存中取出，则需要另外1.5秒（/ 2秒）才能开始使用。
我在Nexus 7（2013）和FairPhone（Android 4.2.2）上测试过它。 我不明白问题在哪里，也许你可以帮助我。 解决方案会很棒，但即使指出原因也会有很大帮助。
App.java的相关代码（扩展应用程序）：
@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"); Gradle文件：

因此Google Analytics出现了问题，但这并不是减缓应用启动速度的主要因素。 主要问题似乎是这样的界限：
Unable to resolve superclass of Landroid/support/v4/app/ActivityCompat21$SharedElementCallbackImpl; (54)
我不知道如何解决这些问题，因为其他具有这类日志消息的StackOverflowpost假设它是关于.jar库并且它在Eclipse上。
像这里： Android – 无法解析超类两者都不适用于我的问题（据我所知）。
在Nexus 7（2013）上，应用程序的启动速度也很慢，但日志文件提供了不同的读数：

虽然我不完全了解其中大部分，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，清单文件的开头：
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。 如何处理这样的问题也很棒。
一些需要解决的问题：
首先，确保已在项目中导入v4和v7支持库…有关更具体的结果,,,请参阅以下内容：
从错误开始： Could not find class 'android.app.AppOpsManager', referenced from method com.google.android.gms.common.GooglePlayServicesUtil.zza < - 检查https://stackoverflow.com/a/29276586/928952
警告：无法识别字符串xml配置名称： com.juliushuijnk.tools.ideagrowr.* < - 检查https://stackoverflow.com/a/23418561/928952
似乎很慢： DexOpt: access denied from Lcom/google/android/gms/common/GooglePlayServicesUtil < - 检查https://stackoverflow.com/a/30052809/928952
Landroid/support/v4/*类的链接< - 检查是否已导入支持v4 jar
VFY: unable to resolve virtual method 630: Landroid/content/res/TypedArray < - 添加支持v7 jar
修复上述内容应有助于加快启动时间
我自己弄清楚了。 所以最后，这是由于我如何实现ActiveAndroid库。
除非您使用有助于AA快速查找模型的配置，否则它会让您的应用程序启动速度非常慢。
我使用以下代码修复它： 如何在Activeandroid中禁用模型扫描
像这样的代码（但我有不同的模型名称）：
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());
现在它开始几乎是即时的。 我仍然不确定为什么我得到所有这些奇怪的logcat条目。 所有’无法解析超类’，可能是某种间接的AA如何在没有配置的情况下运行的神器。 自从我添加配置以来，这些行已经消失了。
这些logcat行混淆了我寻找与gradle和支持库有关的答案，但这不是问题的起源。
所以我应该从一开始就实现了这种配置。 但是它在AA上写的方式让人觉得“很高兴”。

所以我了解到，下次当我看到一些我认为“很高兴”的东西时，我应该在评论中写下我的假设，所以如果遇到问题，我可以很快看到我可能需要改变的地方。
感谢Danielson尝试帮助:)。
Android应用程序开始运行缓慢，但在缓慢启动后工作正常 ，这是因为当您的应用程序被破坏并且时间应用程序缓存变得清晰（如果您的清算），或者来自settings-> apps-> yourapp这两个中的任何一个。再次启动应用程序，那时你会发现这个问题。
