Question

将我们的应用程序上载到Google Play商店时，Google的发布前报告表明该应用程序崩溃了，并出现了空指针异常。问题仅与在华为设备中实施KeyStore有关。

Stacktrace：

Fatal Exception: java.lang.NullPointerException: Attempt to invoke interface method 'int android.security.IKeystoreService.del(java.lang.String, int)' on a null object reference
       at android.security.KeyStore.delete(KeyStore.java:186)

我正在使用Google的Tink库来实现Keystore。库与错误无关。没有库仍然会发生错误。

下面是代码：

@Throws(Exception::class)
private fun getOrGenerateNewKeysetHandle(): KeysetHandle {
    return AndroidKeysetManager.Builder()
        .withSharedPref(this, "KEYSET", "PREF")
        .withKeyTemplate(AeadKeyTemplates.AES256_GCM)
        .withMasterKeyUri(REIWA_MASTER_KEY_URI)
        .build()
        .keysetHandle
}

我认为它必须与设备的密钥库实现有关。

任何帮助将不胜感激。

禁用与AndroidKeysetManager.doNotUseKeystore()的Keystore集成。

Android-华为设备的android.security.IKeystoreService.del中的NullPointerException
