Question

我的应用程序无法启动，我的logcat在下面，我无法理解此错误，我是初学者，我犯了什么错误，所以我遇到了这个错误，在这里我发现了类似的问题，但是答案太混乱了，我无法得到E/LoadedApk: Unable to instantiate appComponentFactory only on Android Q (API 29)

也得到了

在此版本中使用了不推荐使用的Gradle功能，使其与Gradle 7.0不兼容。使用“ --warning-mode all”来显示各个弃用警告。

我的gradle.build是

    apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
compileSdkVersion 30
buildToolsVersion "30.0.0"

defaultConfig {
    applicationId "com.example.somusmall"
    minSdkVersion 16
    targetSdkVersion 30
    versionCode 1
    versionName "1.0"
    multiDexEnabled true


    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

}

dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.1'
implementation 'androidx.multidex:multidex:2.0.1'

testImplementation 'junit:junit:4.12'

androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

}

我的清单文件是

<?xml version="1.0" encoding="utf-8"?>

尝试将上述类添加到proguard-rules中。

 -keep class androidx.core.app.CoreComponentFactory { *; }
