【中文标题】如何摆脱 App 在启动时崩溃?【英文标题】:How get rid from App getting crashed on launch? 【发布时间】:2022-01-17 19:53:29 【问题描述】:启动时应用崩溃,
将 Gradle 插件 4.x.x 更新到 7.0.4 并将 Dagger2 迁移到 Hilt。
并将 Kotlin 更新到 1.6.0。
在 Application 类上添加了 @@HiltandroidApp
。
应用 Multidex 但不起作用。
尝试其他一些解决方案,但没有帮助。
请查看日志。

更新 gradle 后,kotlin 并将 hilt 添加到根级 Gradle 中:
buildscript
ext
kotlin_version = "1.6.0"
apollo_version = '2.5.10'
repositories
google()
jcenter()
mavenCentral()
dependencies
classpath 'com.android.tools.build:gradle:7.0.4'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.3.10'
classpath 'com.google.firebase:firebase-crashlytics-gradle:2.8.1'
classpath 'com.google.dagger:hilt-android-gradle-plugin:2.40.5'
classpath "com.apollographql.apollo:apollo-gradle-plugin:$apollo_version"
allprojects
repositories
google()
jcenter()
maven url 'https://jitpack.io'
task clean(type: Delete)
delete rootProject.buildDir
这是应用程序类:
@HiltAndroidApp
class BaseApplication : Application(), LifecycleObserver
private val TAG = "BaseApplication"
companion object
lateinit var instance: BaseApplication
private set
override fun attachBaseContext(base: Context?)
// MultiDex.install(base)
super.attachBaseContext(base)
override fun onCreate()
ActivityLifecycleCallback.register(this)
super.onCreate()
instance = this
userAgent = Util.getUserAgent(this, "AdaptiveExoplayer")
FirebaseCrashlytics.getInstance().setCrashlyticsCollectionEnabled(!BuildConfig.DEBUG)
ProcessLifecycleOwner.get()
.lifecycle
.addObserver(this)
这是AndroidManifest.xml
的<application>
标签
<application
android:name=".base.BaseApplication"
android:allowBackup="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:requestLegacyExternalStorage="true"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:networkSecurityConfig="@xml/network_config"
android:largeHeap="true"
android:theme="@style/AppTheme"
android:usesCleartextTraffic="true">
大多数解决方案都说添加 Multidex 或清理并重建项目或使缓存无效并重新启动。尝试了大多数解决方案,但没有帮助。
【问题讨论】:
添加你的 BaseApplication 类,这里没有足够的信息。 @Booger 请看我已经更新了帖子。 TIA。 仍然没有足够的信息,因为我们看不到 Application 类的包...我会将完整的包添加到清单中。 【参考方案1】:问题出在我的模块级 gradle 文件中。我使用的是annotationProcessor
而不是kapt
。
annotationProcessor 'com.google.dagger:hilt-compiler:2.40.5'
然后改成
kapt 'com.google.dagger:hilt-compiler:2.40.5'
【讨论】:
【参考方案2】:尝试将清单更改为:
android:name=".base.BaseApplication"
到:
android:name="tech.xyz.android.base.BaseApplication"
【讨论】:
试过但没用。 此问题已解决。将annotationProcessor
替换为kapt
