更改Api.js下的这段文件，改成下文，因为路径不对，我也不清楚为什么，有人知道的话，给我私聊，万分感谢。

this.locations = {
    root: self.root,
    www: path.join(self.root, 'assets/www'),
    res: path.join(self.root, 'res'),
    platformWww: path.join(self.root, 'platform_www'),
    configXml: path.join(self.root, 'app/src/main/res/xml/config.xml'),
    defaultConfigXml: path.join(self.root, 'cordova/defaults.xml'),
    strings: path.join(self.root, 'app/src/main/res/values/strings.xml'),
    manifest: path.join(self.root, 'app/src/main/AndroidManifest.xml'),
    build: path.join(self.root, 'build'),
    javaSrc: path.join(self.root, 'app/src/main/java/'),
    // NOTE: Due to platformApi spec we need to return relative paths here
    cordovaJs: 'bin/templates/project/assets/www/cordova.js',
    cordovaJsSrc: 'cordova-js-src'
};

我发生这个错误是因为我在插件中加入了第三方jar包，加入以后就可以打包成功了。

我在网上还看到过一个方法，我没成功，但有可能是解决的你的错误。

1. Remove the platform: ionic cordova platform rm android
2. Delete the following folders from your app folder: platforms, plugins & www
3. Make sure your dependencies are available by running: npm install
4. Add back the platform, this step will recreate the folders deleted in step 2 above: ionic cordova platform add android
5. Finally, build your app: ionic cordova build android
