从Cordova使用Adobe Acrobat打开PDF

我用科尔多瓦的代码打开文件,

var customPlugin = {
    createEvent : function(success, failure, action,arg1) {
        cordova.exec(success, // success callback function
        failure, // error callback function
        'Utils', // mapped to our native Java class
        action, // with this action name
        [arg1]);
    }
}

这里的“Utils”指的是我的Java类,我在其中编写了下面提到的openFile函数,

// open the file
private boolean openFile(String fileName, String contentType)
        throws JSONException {
File file = new File(fileName);

if (file.exists()) {
    try {
        Uri path = Uri.fromFile(file);
        PackageManager packageManager = this.cordova.getActivity()
                .getPackageManager();
        String application_id = "com.processdrive.novema";
        try {
            PackageInfo packageInfo = packageManager.getPackageInfo(
                    this.cordova.getActivity().getPackageName(), 0);
            application_id  = packageInfo.packageName;
        } catch (NameNotFoundException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        if (Build.VERSION.SDK_INT >= 24) {             
            path = FileProvider.getUriForFile(this.cordova.getActivity(),
                application_id + ".provider",
                file);
        }
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
        intent.setDataAndType(path, contentType);
        cordova.getActivity().startActivity(intent);
        return true;
    } catch (android.content.ActivityNotFoundException e) {
        return false;
    }
} else {
    return false;
}

}

上面的代码在低于android 7的版本中可以正常工作,但是在高于android 7的版本中,它不能处理PDF文件中编辑的内容。
