升级 Cordova 的相机插件时 Android 构建错误

Question

将 cordova 相机插件从 2.1.1 更新到 2.3.1 后，我遇到了构建错误。

版本详情：

cordova version: 6.3.1,
cordova-plugin-camera 2.1.1 "Camera"

我在做什么：

cordova plugin remove cordova-plugin-camera --save
cordova plugin add cordova-plugin-camera --save

我看到 config.xml 文件已更新为：

<plugin name="cordova-plugin-camera" spec="~2.3.1" />

当我构建 cordova android build 时出现以下错误：

Error: cmd: Command failed with exit code 1 Error output:

Answer 1

您应该将 cordova-plugin-camera 升级到 1.1 版

Answer 2

我今天遇到了同样的问题。我通过重新安装插件cordova-plugin-compat 修复了它。 由于依赖关系，我使用了 --force。

cordova plugin remove cordova-plugin-compat --force
cordova plugin add cordova-plugin-compat

Answer 3

我得到了完全相同的错误。这其实是cordova-plugin-compat插件（1.0）的老版本造成的，升级到1.1（最新）就可以了。

这就是我所做的，

1. 删除所有平台

   cordova 平台移除 android

   cordova 平台移除 ios

2. 删除旧插件并添加新插件

   cordova 插件删除 cordova-plugin-compat

   cordova 插件添加cordova-plugin-compat

3. 重新添加所有平台

   cordova平台添加android

   cordova平台添加ios

4. 重新编译，一切正常！

Answer 4

我们通过强制安装 1.1.0 版解决了这个问题。

这是我们从 CLI 运行的命令：

cordova plugin remove cordova-plugin-compat --force
cordova plugin add cordova-plugin-compat@1.1.0

Answer 5

我已对以下方法进行了更改。

// intiatiate you action accordingly
if (action.equals("takePicture")) {
            this.srcType = CAMERA;
            this.destType = FILE_URI;
            this.saveToPhotoAlbum = false;
            this.targetHeight = 0;
            this.targetWidth = 0;
            this.encodingType = JPEG;
            this.mediaType = PICTURE;
            this.mQuality = 50;

            //
            this.destType = args.getInt(1);
            this.srcType = args.getInt(2);
            this.mQuality = args.getInt(0);
            this.targetWidth = args.getInt(3);
            this.targetHeight = args.getInt(4);
            this.encodingType = args.getInt(5);
            this.mediaType = args.getInt(6);
            this.allowEdit = args.getBoolean(7);
            this.correctOrientation = args.getBoolean(8);
            this.saveToPhotoAlbum = args.getBoolean(9);

            // If the user specifies a 0 or smaller width/height
            // make it -1 so later comparisons succeed
            if (this.targetWidth < 1) {
                this.targetWidth = -1;
            }
            if (this.targetHeight < 1) {
                this.targetHeight = -1;
            }

              if (this.targetHeight == -1 && this.targetWidth == -1 && this.mQuality == 100 &&
                    !this.correctOrientation && this.encodingType == PNG && this.srcType == CAMERA) {
                this.encodingType = JPEG;
            }

            try {
                if (this.srcType == CAMERA) {
                    this.callTakePicture(destType, encodingType);
                }
                else if ((this.srcType == PHOTOLIBRARY) || (this.srcType == SAVEDPHOTOALBUM)) {
                    // FIXME: Stop always requesting the permission
                    if(!PermissionHelper.hasPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE)) {
                        PermissionHelper.requestPermission(this, SAVE_TO_ALBUM_SEC, Manifest.permission.READ_EXTERNAL_STORAGE);
                    } else {
                        this.getImage(this.srcType, destType, encodingType);
                    }
                }
            }
            catch (IllegalArgumentException e)
            {
                callbackContext.error("Illegal Argument Exception");
                PluginResult r = new PluginResult(PluginResult.Status.ERROR);
                callbackContext.sendPluginResult(r);
                return true;
            }

            PluginResult r = new PluginResult(PluginResult.Status.NO_RESULT);
            r.setKeepCallback(true);
            callbackContext.sendPluginResult(r);

            return true;
        }
        return false;
    }

Answer 6

我也收到了来自相机插件 2.3.1 的错误。这是因为依赖于 cordova-plugin-compat 来获取应用程序 ID。删除 cordova-plugin-compat 并安装 1.1.0，对我不起作用。

要解决此问题，请从“src/android/CameraLauncher.java”中删除此代码：

140      -     this.applicationId = (String) BuildHelper.getBuildConfigValue(cordova.getActivity(), "APPLICATION_ID");
141      -     this.applicationId = preferences.getString("applicationId", this.applicationId);

并添加：

140      +     this.applicationId = cordova.getActivity().getPackageName();
