android - java.lang.ClassNotFoundException：在路径上找不到类“com.huawei.hiai.common.AIRuntimeException”

问题描述

我尝试使用HiAI创建一个应用程序来尝试图像超分辨率。

活动的代码如下所示：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_isr);

    Thread thread = new Thread(
            new Runnable() {
                @Override
                public void run() {
                    Intent intent = new Intent();
                    intent.setType("image/*");
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    startActivityForResult(Intent.createChooser(intent, "Select Picture"),
                            1001);
                }
            }
    );
    thread.start();
    try {
        thread.join();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1001 && resultCode == RESULT_OK) {

        // Let's read picked image data - its URI
        Uri pickedImage = data.getData();
        // Let's read picked image path using content resolver
        String[] filePath = {MediaStore.Images.Media.DATA};
        Cursor cursor = getContentResolver().query(pickedImage, filePath, null, null, null);
        cursor.moveToFirst();
        String imagePath = cursor.getString(cursor.getColumnIndex(filePath[0]));


        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Bitmap.Config.ARGB_8888;

        bitmap = BitmapFactory.decodeFile(imagePath, options);

        // Do something with the bitmap

        bitmap = ShrinkBitmap(imagePath, 700, 500);

        ImageView img = findViewById(R.id.imageView);
        img.setImageBitmap(bitmap);

        // At the end remember to close the cursor or you will end with the RuntimeException!
        cursor.close();
    }
}

public void press(View v) {
    Log.i("AI", "Feladat előtt");

    VisionBase.init(this, new ConnectionCallback() {
        @Override
        public void onServiceConnect() {
        }

        @Override
        public void onServiceDisconnect() {
        }
    });

    /** Define class detector，the context of this project is the input parameter */
    ImageSuperResolution superResolution = new ImageSuperResolution(this);
    /** Define the frame, put the bitmap that needs to detect the image into the frame*/
    Frame frame = new Frame();
    /** BitmapFactory.decodeFile input resource file path*/
    //Bitmap bitmap = BitmapFactory.decodeFile(null); //TODO
    frame.setBitmap(bitmap);
    /** Define and set super-resolution parameters*/
    SuperResolutionConfiguration paras = new SuperResolutionConfiguration(
            SuperResolutionConfiguration.SISR_SCALE_3X,
            SuperResolutionConfiguration.SISR_QUALITY_HIGH);
    superResolution.setSuperResolutionConfiguration(paras);
    /** Run super-resolution and get result of processing */
    ImageResult result = superResolution.doSuperResolution(frame, null);
    /** After the results are processed to get bitmap*/
    Bitmap bmp = result.getBitmap();
    /** Note: The result and the Bitmap in the result must be NULL, but also to determine whether the returned error code is 0 (0 means no error)*/


    /** Source release */
    VisionBase.destroy();
    Log.i("AI", "Destroy után");

    v.setVisibility(View.GONE);

    ImageView img = findViewById(R.id.imageView);
    img.setImageBitmap(bmp);

    Log.i("AI", "Kirajzolva");
}

Bitmap ShrinkBitmap(String file, int width, int height) {

    BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
    bmpFactoryOptions.inJustDecodeBounds = true;
    Bitmap bitmap;
    BitmapFactory.decodeFile(file, bmpFactoryOptions);

    int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight / (float) height);
    int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth / (float) width);

    if (heightRatio > 1 || widthRatio > 1) {
        if (heightRatio > widthRatio) {
            bmpFactoryOptions.inSampleSize = heightRatio;
        } else {
            bmpFactoryOptions.inSampleSize = widthRatio;
        }
    }

    bmpFactoryOptions.inJustDecodeBounds = false;
    bmpFactoryOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;
    bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);
    return bitmap;
}

它启动图库应用程序，选择一张图片，将图片裁剪为一个好的分辨率和一个按钮来启动 AI 功能的工作。它应该在图像视图中显示图片。但是，当我在手机上运行应用程序时，按下按钮让 AI 执行此操作后，出现以下 4 个错误：

java.lang.IllegalStateException: Could not execute method for android:onClick

...

app/libs 文件夹中有 3 个文件：

build.gradle 看起来像这样：

apply plugin: 'com.android.application'
android {
    compileSdkVersion 27
    defaultConfig {
        multiDexEnabled true
        applicationId "hu.hiai.aitestapp"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation(name: 'vision-oversea-release', ext: 'aar')

    implementation project(':huawei-hiai-vision')
    implementation files('libs/Huawei_IDE.jar')
}

repositories {
     flatDir {
          dirs 'libs'
     }
}

如果有人能提供帮助，我将不胜感激！

解决方案

我的同事也有类似的问题，发生在他的代码调用 FaceCompare 方法时。碰巧在 HiAI 库中没有这样的类。那么我们该怎么办？

如果在 UI 线程中调用 FaceCompare 方法，它看起来会被抛​​出，所以我们将它移动到另一个线程，我们不再遇到该异常。
