Error -1 typically means that your phone doesn't support running TensorFlow.js in an embedded webview. Have you tried a site like https://emojiscavengerhunt.withgoogle.com/ in Chrome on your device and does it run well?
Hello thanks for you're answer

it show just loading and loading nothinbg more.
maybe it don't support tensorflow.js

There is something you can do Karl; see this AI and classify picture . If you want to play with the Image Classifier, Tim has shown it runs in the free genemotion emulator. Load the emulator on your PC and genemotion should allow you to use the AI.
That suggests to me that your tablet GPU doesn't support OpenGL ES 3.0, which is needed for WebGL 2.0. You'll have to explore another route, such as the emulator option.
