Androidでjava.lang.NullPointerExceptionを取得する

8

ndkのクラッシュにFirebase crashlyticsベータ版を使用しています。ここに記載されているすべての手順に従います。しかし、問題が発生し、シンボルファイルをアップロードできません。私がタスクを実行しようとするときはいつでも./gradlew uploadCrashlyticsSymbolFileDebug --stacktraceそれは言うjava.lang.NullPointerException。しかし、なぜ、どこでnullになるのでしょうか。

これがこのタスクの完全なスタックトレースです 

> Task :app:generateCrashlyticsSymbolFileDebug FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:generateCrashlyticsSymbolFileDebug'.
> java.lang.NullPointerException (no error message)

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:generateCrashlyticsSymbolFileDebug'.

nativeSymbolUploadEnabled内でデバッグとリリースの両方を削除buildTypesした場合でも、NPEを取得できますか？
— ハリーティモシー
@harrytmthyなしでタスクnativeSymbolUploadEnabledを実行uploadCrashlyticsSymbolFileDebugする方法は？これはndk crashlyticsの必須パラメーターです

私のプロジェクトで同じ問題が発生しています。GitHub経由で報告しました：github.com/firebase/firebase-android-sdk/issues/1357。私も彼らの開発サポートに連絡しました、そして彼らはチームが現在これを調査していると言います。私の推測では、それは静的ライブラリの1つを解析することによって引き起こされると考えられます。
— フレデリク
理由はわかりませんが、現在このエラーは発生していません。いくつか変更を加えましたが、思い出せません。

一緒にアセンブル、インストール、実行しないでください。特に、並列ビルドを有効にしている場合は、問題になります。installとinstallDeviceは異なります。インストールはAndroidプラグインから行われ、すべてのデバイスにインストールされます。installDeviceはプラグインからのもので、特定のデバイスにインストールされます。デフォルトでは1つ目は、-PdeviceId =でオーバーライドできます。

あなたは以下のものを試すことができます：

GradleとAndroidプラグインのバージョンを私たちと共有できますか？./gradlew runDebugだけで試してください。これはあなたのために組み立ててインストールします。通常のAndroid installDebugタスクの後でstartDebugを実行することもできます。これは、インストールして開始するのではなく、単に開始します。これは、インストールタスクを自分で実行する必要がある場合に便利です。並列を有効にしている場合、-no-parallelコマンドライン引数を使用して試すことができますか？
