Google Mobile Vision库未下载 [英] Google Mobile Vision library not downloading
问题描述
我正在尝试在我的应用程序中实现Google Mobile Vision TextRecogniser API，以读取给定图像的文本.当我尝试使用该功能时，出现此错误:
W/DynamiteModule: Local module descriptor class for com.google.android.gms.vision.dynamite not found.
I/DynamiteModule: Considering local module com.google.android.gms.vision.dynamite:0 and remote module com.google.android.gms.vision.dynamite:801
I/DynamiteModule: Selected remote version of com.google.android.gms.vision.dynamite, version >= 801
W/System: ClassLoader referenced unknown path: /data/user_de/0/com.google.android.gms/app_chimera/m/00000005/n/arm64-v8a
D/ApplicationLoaders: ignored Vulkan layer search path /data/app/com.google.android.gms-1/lib/arm64:/system/fake-libs64:/data/app/com.google.android.gms-1/base.apk!/lib/arm64-v8a for namespace 0x7a2e8c60f0
I/Vision: Loading libocr library
I/Vision: libocr load status: false
I/TextRecognizerCreatorImpl: Requesting download for native text recognizer
W/TextNativeHandle: Native handle not yet available. Reverting to no-op handle.
我认为这意味着图书馆没有下载到手机中.
我已针对常见错误源进行了故障排除，包括缺少互联网连接，缺少内存，缺少依赖项，重新启动电话，更新Google Play服务，稍等片刻.Google存储库和Play服务也在Android Studio中进行了更新. /p>
但是，即使在其他设备上尝试运行我的应用程序，我仍然会遇到相同的错误.
我相信下载是由Google Play服务应用执行的.库是作为zip文件下载到文件夹中的
/data/data/com.google.android.gms/cache/downloadservice
并提取到
/data/data/com.google.android.gms/files/com.google.android.gms.vision
并且我们的应用程序始终会检查路径中的库
06-02 22:43:53.379 30258-30419/pzy64.searchbot I/Vision: Loading library libocr.so
如果文件不存在则显示错误
06-02 22:43:53.475 30258-30419/pzy64.searchbot I/Vision: libocr.so library load status: false
否则
06-03 09:42:33.372 23451-24679/pzy64.searchbot I/Vision: libocr.so library load status: true
下载后， 就我而言(ARM)的文件夹大小
/data/data/com.google.android.gms/files/com.google.android.gms.vision
大约5MB.(因此下载的文件小于此大小，大小可能因不同的体系结构而异.在我的Asus Phone(x86)中下载花费了更多时间).
查看我的Logcat-(使用视觉"进行过滤).

I am trying to implement the Google Mobile Vision TextRecogniser API into my app, to read text off a given Image. When I try to use the feature, I get this error:
W/DynamiteModule: Local module descriptor class for com.google.android.gms.vision.dynamite not found.
I/DynamiteModule: Considering local module com.google.android.gms.vision.dynamite:0 and remote module com.google.android.gms.vision.dynamite:801

I/Vision: Loading libocr library
I/Vision: libocr load status: false
I/TextRecognizerCreatorImpl: Requesting download for native text recognizer
W/TextNativeHandle: Native handle not yet available. Reverting to no-op handle.
Meaning, I believe, that the library wasnt downloaded to the phone.
I have troubleshooted for common error sources, including missing internet connection, lack of memory, missing dependencies, rebooting the phone, updating Google play services, waiting a while etc. Google repository and Play services are also updated in Android studio.
Yet, I still get the same error, even when trying my App on different devices.
I believe that the download is performed by the Google Play Service App. The Libraries are downloaded as a zip file in the folder
/data/data/com.google.android.gms/cache/downloadservice
and are extracted to
/data/data/com.google.android.gms/files/com.google.android.gms.vision
and our app always check for the library in path
06-02 22:43:53.379 30258-30419/pzy64.searchbot I/Vision: Loading library libocr.so
which shows the error if the files are absent
06-02 22:43:53.475 30258-30419/pzy64.searchbot I/Vision: libocr.so library load status: false
otherwise
06-03 09:42:33.372 23451-24679/pzy64.searchbot I/Vision: libocr.so library load status: true
After download, In my case (ARM) the folder size of
/data/data/com.google.android.gms/files/com.google.android.gms.vision
is around 5MB.(So the file downloaded is less than this size, The size may vary for different architecture .It took more time to download in my Asus Phone (x86)).
See my Logcat - (filter using 'Vision').
