android - Renderscript:加载 ScriptC 脚本失败

Question

当 Google 发布预发布报告时，有 1 台设备(Huawei Mate 9)总是出现此崩溃:“加载 ScriptC 脚本失败”。我从未在任何其他设备上遇到过这个问题。

首先，我遇到了原生渲染脚本崩溃。

然后我收到加载失败的正式消息(我在 AsyncTask 中加载渲染脚本):

这是我的 gradle 设置:

compileSdkVersion 28
buildToolsVersion '27.0.3'
defaultConfig {
    applicationId "com.example.renderscripttest"
    minSdkVersion 17
    targetSdkVersion 28
    versionCode 40
    versionName "1.1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
    renderscriptTargetApi 17
    renderscriptSupportModeEnabled true
}

我该如何解决这个问题？

Answer 1

我收到“加载 ScriptC 脚本失败”的崩溃报告。在运行 Oreo 8.1 的 Gigaset GS185 上

经过长时间的调查，我们发现只有当应用程序移动到 SD 卡时才会出现错误。也许谷歌也会在外部存储上安装应用程序进行测试？我认为 Android 在运行时编译 RenderScript，如果脚本在 SD 卡上，可能会失败。
