java.lang.RuntimeException：無法獲取提供商 com.google.firebase.provider.FirebaseInitProvider：java.lang.NullPointerException

Question

您好，我正在嘗試為其發布變體構建我們的應用程序，但在首次運行該應用程序時會觸發以下錯誤。

復制步驟：

1. 構建簽名的 apk
2. 在模擬器上安裝apk
3. 應用崩潰

巧合的是，這只在發布時運行，但在調試時它工作正常。 我已將 -dontshrink、-dontoptimize、-dontobfuscate 添加到我的 proguard 規則中，這就是我可以生成堆棧跟蹤的原因。

構建 Gradle 值

android {
    compileSdkVersion 33
    buildToolsVersion "33.0.0"
    defaultConfig {
        minSdkVersion 23
        targetSdkVersion 33
        versionCode 1
        versionName '0.1.0'
        consumerProguardFiles "consumer-rules.pro"
}

minifyEnabled、textCoverageEnabled、shrinkResources 都變成 false

Firebase 圖書館

"analytics"  : "com.google.firebase:firebase-analytics-ktx",
"crashlytics": "com.google.firebase:firebase-crashlytics-ktx",
"config"     : "com.google.firebase:firebase-config-ktx",

Answer 1

對於可能遇到此問題的每個人，這是因為 Dexguard 混淆與我正在使用的某些庫沖突。 在這種情況下，值得注意的是 firebase 庫、crashlytics 和脫糖 SDK。

降低 firebase 和脫糖 SDK 到舊版本解決了我的問題。

如果您下次遇到這種情況，請仔細檢查您的提交並查找 SDK 依賴項更新。 從那里開始，因為日志不會有任何幫助。

祝你好運！
