android 调试中的结构初始化非常慢
very slow fabric initialization in android debug
我正在尝试在 android 上集成 fabric（包括 crashlytics 和 NDK 支持和答案），我让它们工作了。
但是，当我尝试调试我的应用程序时，fabric 需要很长时间（大约 500 万）才能完成它的工作。
这是日志：

如您所见，
Verification of boolean io.fabric.sdk.android.services.settings.Settings.loadSettingsSkippingCache() took 181.194s
花了将近300万，
Attempting to load unwinder...
也赚了300万
当我尝试在没有附加调试器的情况下启动应用程序时（只是 运行 而不是在 android studio 中进行调试），应用程序启动得很好。
任何关于在哪里寻找这个问题的指导将不胜感激。

稍加挖掘后，实际上是 JniNativeApi 调用
System.loadLibrary("crashlytics");
首先，这需要很多时间。第二次冻结还不知道。
这很奇怪，因为图书馆看起来很轻（libcrashlytics.so 大约 600ko）

这是我的 gradle 构建的结构：
在顶层 proj.android 文件夹中有一个 build.gradle，其中包含所有子项目通用的所有配置选项（abiFilters、minSdkVersion ...）：
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
ext {
minSdkVersion = 24
targetSdkVersion = 26
compileSdkVersion = 26
buildToolsVersion = '26.0.1'
abiFilters = [
'XXX'
]
cppDebugFlags = [
'YYYYYY'
]
cppReleaseFlags = [
'ZZZZZ'
]
arguments = [
'-DANDROID_TOOLCHAIN=clang',
'-DANDROID_PLATFORM=android-24',
'-DANDROID_STL=c++_static',
'-DANDROID_CPP_FEATURES=rtti exceptions'
]
}
task wrapper(type: Wrapper) {
gradleVersion = '4.1'
}
task clean(type: Delete) {
delete 'stuff'
}
然后我的所有子项目都有一个 build.gradle 文件（1 com.android.application 和 4 com.android.library）
我认为库 build.gradle 文件不相关，因为我没有在其中放置任何与结构相关的初始化，所以这是我的 build.gradle 主要应用程序：
buildscript {
repositories {
maven { url 'https://maven.fabric.io/public' }
}
dependencies {
// These docs use an open ended version so that our plugin
// can be updated quickly in response to Android tooling updates

我还在清单中添加了
中的 api 键
...
<application android:label="@string/app_name"
android:icon="@drawable/icon">

<meta-data android:name="android.app.lib_name"
android:value="name" />
<meta-data android:name="io.fabric.ApiKey"
android:value="API Key"
/>
...
最后我在 activity 的 onCreate 方法中设置 Fabric，如下所示：
// TODO uncomment this when testing's over
//Crashlytics crashlyticsKit = new Crashlytics.Builder().core(new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build()).build();
//Fabric.with(this, crashlyticsKit);
Fabric fabric = new Fabric.Builder(this).kits(new Crashlytics(), new CrashlyticsNdk())
.debuggable(true)
.build();
Fabric.with(fabric);
非常感谢您的快速回答，希望补充信息对您有所帮助！

我在几个设备上测试过（galaxy tab s3 @7.0 & google pixel C @7.1.1），没有任何区别，问题仍然存在。
我现在不太清楚，但是我重新启动笔记本电脑后问题就消失了。我猜这与 adb 调试器不知何故卡住了有关？
